I. INTRODUCTION

Gun Propulsion Research Group of Propulsion Division, WSRL has evaluatedseveral approaches to the task of acquisition and processing of data from gunballistic ranges. Overseas laboratories visited by the author in recent yearsuse systems based on data transferral (in either analog or digital form) tomagnetic media, with subsequent processing by a large central laboratorycomputer or by a dedicated minicomputer. However, recent advances in dataacquisition and processing equipment mean that such a system is notnecessarily the most efficient or economic. It was decided that the task ofdata handling at the two ranges operated by the Group at DRCS, and theportability required for operation at other sites, could best be met by asystem containing flexible self-contained data acquisition units under thecontrol of a programmable desktop computer. Such a system has successfullybeen put into operation at WSRL. Additional output capability has beenachieved by the addition of a plotter and a small line-printer. Data storageand software access will be improved in the near future by incorporation of adiskette drive and a cartridge tape unit.

2. SYSTEM CONFIGURATION

2.1 System Control and Data Processing

These functions are fulfilled by a Hewlett-Packard HP9825A DesktopComputer, equipped with 23K bytes of user memory. This computer hascertain features which suit it to the particular problems associated withthe management of ballistic range data. In general, the task does notdemand sophisticated software. The control and processing sequence isbasically linear in operation, but large quantities of digital data have tobe acquired from several sources and processed efficiently and flexibly.The HP9825A is a fast compact computer, and the availability of severaltypes of compatible interface means that it may be readily incorporatedinto systems with different digital I/0 requirements. Software for theHP9825A is written in Hewlett-Packard's programming language called HPL,(ref.1). This language has strong similarities with ANSI BASIC and anyprogrammer familiar with BASIC will rapidly learn HPL. The execution of theprograms described in this report requires the installation of certainread-only memories (ROMs). These are for Advanced Programming, General 1/OProgramming, Extended I/O Programming, String Variable Programming, andHP9872 Plotter Programming. Programs used by the HP9825A are normallystored on tape cartridges, for which the HP9825A has its own internal tapedrive. This drive is also used to access and store data. In addition, thecomputer includes a small internal thermal printer for written output. Auseful feature of the HP9825A is that it has a number of programmer-definable keys (Special Function or "soft" keys) which are of value whenthe system is to be operated by personnel with limited knowledge ofprogramuing in HPL.

2.2 Graphic Display

Hard-copy graphics are obtained using a Hewlett-Packard 9872A Plotter.This plotter will accept paper up to A3 size and writes using any one offour user-selectable pens. This is a flexible device, which iscontrollable by many host computers as it has its own internal high-levellanguage. It also responds to HPL commands from the HP9825A. It isconnected to the host computer using its own IEEE-488 interface (ref.2).

- 3 - WSRL-0209-TR

2.3 Data Storage for Future Reference

This is accomplished using the internal cartridge tape unit of the 11P9825Aand designated data tapes. This method has certain programming limitationsbut has proved adequate. A Hewlett-Packard 9885M Diskette drive andHP9875A Cartridge Tape Unit will be incorporated into the system at a laterdate. These items will greatly enhance system flexibility.

2.4 Printed Output

The small thermal printer of the HP9825A computer is adequate for outputduring normal operation at the ballistic ranges, but is too small torgeneral use or for listing of programs. An Epson MX-80 printer isconnected to the computer when such usage is required, using its ownIEEE-488 interface.

2.5 Data Acquisition Devices

Two types of digital transient recorder are available at DRCS for use withthe system:

2.5.1 Biomation 1015

This device (ref.3) is a four-channel unit with 1024 10-bit wordsavailable per channel. The minimum acquisition interval is 0.01millisecond which is marginal, but acceptable, for the extremely rapidevents monitored during gun firings. It uses a non-standard digitalinterface which is described in section 2.6. The Biomation 1015 has asmall range of remotely controllable functions. This means that the

operator has to use panel switches to initiate actions which can hesoftware-controlled in some recorders of more recent design.

2.5.2 Datalab DL2800

This multichannel unit (ref.4) consists of a functional controller,which sets parameters such as acquisition rates, trigger levels andoperating mode, and up to eight memory modules which are effectivelyseparate channels. Each memory has 4096 10-bit words and the miimumIacquisition interval is 0.5 microsecond. This device is connected t,the system controller by means of a digital interface which implementsalmost all of the transfer and control capabilities of the IEEE-488interface standard (ref.2).

2.6 Interfaces

The HP9825A computer is connected to the Datalab DL2800, the plotter, theprinter, and the diskette drive using the Hewlett-Packard 98034A HP-1Binterface (ref.5), which is that company's implementation of the IEEE-488standard. Up to fourteen peripheral devices can be controlled using thisinterface. The Biomation 1015 transient recorder is linked to the computerusing a Hewlett-Packard 98032A 16-bit interface (ref.6). The connectorterminating the cable from the HP98032A interface has been specificallyconfigured to suit the format of the digital output terminal of theBiomation 1015 and a prototype projectile velocity counter. The specificdetails of this non-standard termination are included in reference 7.

2.7 Program Security and Protection

HPL has a facility to secure programs and prevent a user displaying them oilthe internal printer of the computer or its front-panel display area. Thiscapability is not used tor these programs. They are secured only againstera sure by thle phys icalI lock inrg of a t ape-p rot ect ioii device oil the tapeca r tr idge. lIn the event ot' accidental erastirt or damage to the tapes inroutine use , master tapes are- available fo r (duplicat ion as reqired.

3. SYSTEM OPERATION

This section is included to given an overview of the way the system functionsas a whole. It is not intended to furnish detailed operating instructions.

3.1 System Connections

The current format of the system requires that phenomena monitored at thegun, such as the pressure and strain histories, projectile exit, and firingimpulse, are recorded on one of the transient recorders. Transducers anddetectors for events at the gun are connected to the recorder usingspecified signal conditioners and amplifiers. The transient recorder isconnected to the computer using the appropriate interface. Externalevents, such as bullet velocity downrange, are read from displays by theoperator, and entered when requested using the computer keyboard.

3.2 Data Acquisition

The transient recorder controls, and those of ancillary equipment, are setto suitable values. The firing is executed, and the digital information isnow available from the recorder's data store. The operator notes anyvelocity information required for keyboard entry to the computer.

3.3 Data Processing

The operator loads the appropriate tape cartridge into the HP9825A computerand turns the power on. All operations to load programs, set constants anddefine the functions of the "soft" keys are performed automatically. Anoperator instruction list is produced on the internal printer whichoutlines program operation and lists the actions performed by the "soft"keys. Such an instruction list is illustrated in figure 1. The operatorenters information when prompted by the computer. The computer then inputsthe digital data from the transient recorder under program control andperforms certain calculations to adjust baselines and to convert the datainto the required units. A Firing Susmmary is printed. The operator isthen requested to use the "soft" keys to designate his output requirements.Typical output options include a printed pressure summnary, or perhaps aplotted representation of the data. Examples of a firing summnary andprinted pressure summnary, and a plotted pressure history, are included infigures 2 and 3 respectively. Figure 2 illustrates the "default" pressuresummuary, which is intentionally brief. This initial summary allows theuser to determine the chronological location of the specific data herequires. lie may then make simple software modifications to print or plotthis information with higher resolution.

3.4 Software Limitations

It is highly unlikely that normal usage of this system will include boththe Biomation and Datalab Transient recorders. It is expected that theusual operating procedure will see the HP9825A associated with either onerecorder or the other for considerable periods of time. Although it wouldbe feasible to develop general software which would optionally controleither transient recorder, significant advantage is gained by using twoseparate programs. The first program, designated "9825131", is used whenthe HP9825A is connected to the Biomation 1015 transient recorder, whilethe second program "9825DL", is used with the Datalab instrument. Theprograms are essentially identical except for areas where consideration hasto be given to the different absolute size of the menories of the tworecorders, and their very different means of transmitting digital data.The existence of two programs poses no practical problem because of thenormal association of the computer with only one of the recorders. Theseparation of the software into two programs leads to improved utilisationiof data storage on magnetic tape. However, this means that Biomat ion andDatalab-sourced data should not be recorded on the same data tape. A thirdprogram, "9825P0", has also been developed which'is used to access andanalyse data obtained by either of the two previous programs and recordedon a tape cartridge. This program can only draw data from this source andthus has no formal data acquisition capability - it is for data processingonly. This program is normally used in the laboratory or officeenvironment to enable detailed examination of data previously obtained.

Listings of these three programs and associated explanatory notes areincluded in Appendices I1, 111, and IV respectively.

4. PROGRAM STRUCTURE

The structure of the three programs described in this paper is essentially thesame and is quite straightforward. The programs are divided into threeprincipal sections - a "driver" section, a group of "direct-execution"routines, and a group of "service" routines. A representative Flow Chart isillustrated in figure 4.

4.1 Driver Section

The driver section of each program is responsible for the setting up ofinitial conditions and for controlling the overall flow of the acquisitionand processing sequence. Initial actions include the assignment of keyvariables and counters and the setting of program flags. The operator isprompted to enter any external data requirements, such as instrumentsettings and titling information. The program then initiates dataacquisition, either from a transient recorder or from a tape cartridge.The operator is then prompted to use one of the output options actuated bythe Special Function Keys (N-f0). The functions of these keys have beensummarised in the print-out illustrated in figure 1.

4.2 Direct-execution Routines

Trhese routines perform the major part of the acquisition, processing andtoutput functions of the program in use. Specifically, routines areincluded which:

(a) Acquire projectile muzzle velocity. (GETVEL)(b) Acquire data from recorder or tape. (GETDAT)(c) Print data summary. (SUMMARY)(d) Execute plot framework. (COMPLOT)(e) Record firing data on tape cartridge. (STORE)(f) Skip unwanted channels or data. (ABORT)

4.3 Service Routines

The service routines are responsible for the establishment of boundaryconditions for the direct-execution routines and for the execution ofcertain administrative functions within the program. The tasks of theseroutines include:

(a) Initialising the plotting areas specified. (PLOTn routines)(b) Establishment of upper limits for the plot axes. (SET LIMITS)(c) Issuing warnings for error conditions. (WARNING)(d) Control of print formats.

Routines (c) and (d) are administrative routines which are not included inthe Flow Diagram (figure 4).

4.4 Program Counters

Certain counters and temporary stores are used within the programs whosefunctions are not immediately obvious. These variables include:

(a) D$ - This variable acts as a general storage for alphanumeric input.Its value is normally transferred to another location aftercertain checks on its magnitude have been satisfied.

Cb) N - The number of the recorder channel currently being processed.This number also designates the plotter pen station associatedwith that channel.

Cc) Q - The total number of firings recorded on a data tape.(d) S - The total number of data files recorded on a data tape. One

firing can generate as many as six files, depending on thenumber of channels in use.

Ce) T - The number of the data tape track in current use.(f) Y - Indicates which of two plot areas on a double plot page is to be

used.(g) Z - Indicates which plot area on a four-plot page is to be used.

4.5 Program Flags

Program flags I throu,? h 6 are used to alert the program logic to certainoperating conditions. The flags have the following meanings when set:

(a) Flag I - Multichannel mode in effect.(b) Flag 2 - Data has been plotted.(c) Flag 3 - Data has been recorded.(d) Flag 4 - Current channel has been plotted.(e) Flag 5 - Current channel has been recorded.(f) Flag 6 - Indicates Biomation-sourced data (Program 9825P0 only).

- 11 - WSRI.-0201 -TR

The setting of flags 2 to 4 is conditional on flag 1. 'The operating modedetermines the function of Flag 5. In single channel use, flag 5 i- oflyencountered in the "set" condition if the user attempts to store firingdata a second time. The computer issues a suitable warning to limit tapewastage. In the multichannel mode, flag 3 "set" and flag 5 "cleared" is icondition which indicates that an earlier channel was recorded, but thatthe current channel has yet to be stored. An appropriate warning Isgenerated to prevent data loss.

APPENDIX I

THE HPL COMPUTING LANGUAGE

The Hewlett-Packard Language (HPL) is a non-standard programming languagewhich has wide currency in the field of desktop computers because of threpopularity of calculators manufactured by that company. HPL has mdnysimilarities to ANSI BASIC (ref.8). Many of the instructions are shortenedversions of the BASIC equivalent and the execution of programs in HPl. andBASIC is very similar. However, it is appropriate at this stage to emphasist,the unique or unusual features of HPL.

1. The Assignment Operator (-v)

HPL uses the horizontal arrow (-*) to indicate the assignment operation.For example, the statement (A-B) means "store the value of the variablecalled A in a location assigned to the variable B". While this operat ionis performed in similar fashion by most computers, it is normalily writtenin the reverse order. For example, BASIC or FORTRAN would use t i-statement (B=A) for this purpose. Multiple assignment statements of theform A-B>C are permitted in HPL.

2. Multiple Statement Lines

HPL allows the use of several statements per line of program coding. Suchstatements are separated by a semi-colon and, with one or two exceptions,are executed strictly left-to-right.

3. Conditional Statements

The "IF" statement takes a similar form to that used by other languages:

If (expression A) (conditional relationship) (expression B) .....

However, in HPL, if the relationship is satisfied, the rest of the currentline, including any multiple statements, is executed. For example:

if A=B ; C d) ; 7r,.-D P

In the absence of instructions to continue elsewhere, the lolloi rig lin,will then be executed. If the relationship is not satisfied, execution ofthe next line occurs.

4. String Variables

HPL handles string variables (alphanumeric data) in a very similar fashionto BASIC. A string variable is denoted by the inclusion of the "$" signin its assignment (for example, AS), and must be appropriately allok.aLedby a prior dimension statement. Similar operations are permitted -ithstring variables under HPL as with BASIC.

WSRL-0209-TR -14-

Appendix 1

5. Program Execution

HPL is similar to BASIC and other simple computing languages, in that thecomputer's processing unit handles execution one line at a time. Programlines are interpreted (translated into internal machine-languageinstructions) and executed sequentially. There is little similarity tothe overall program compilation required, for example, by FORTRAN. Thismeans that execution can be stopped either from the keyboard, or routinelyduring the program, and changes to the coding or to the values of"variables made. This can be a very useful feature during the analysis ofresults, or to adjust incorrectly entered or acquired data.

USER NOTES FOR PROGRAM "9825B1"

Line Number Comment s

4 Allocates memory for number of channels, title, serialnumber, velocity, two comment I ihes, pressure andmiscellaneous constants.

6,7 Normal start point after initialisation, sets imitialvalues. Designates interface number 2 (11P98032A) -sdata source.

1- Increments Se rial Number with iuull dati ent iv.

2b Ratio (applied volts/fuill scale volts) Is expressed as a10-bit word with full scale volts = 1023. 10-toldmagnification is applied to make best use of integer-precision storage later.

51 "GETVEL" is written as a routi ne because it is plannedto acquire this data electronically at a later date.

53-60 R is average baseline di sp I acement of first 2'points. Because a 16-bit word is transferred from theinterface, and only the first 10-bits are valid, theleft-most 6 bits are "anded out". Data value 22t(decimal) starts the Biomation 1015 output sequence,,while 228 interrupts that sequence and returns therecorder to its normal state.

74 "COMPLOT" is the common plotting routine used by all theavailable plot formats. The internal l)aramefter (pl) isused to adjust the positions of labels to different pagtesizes and shapes.

111 "STORE" records data on magnetic tape cartridge.

119 1000 is added to M as a signal that the data isBiomat ion-sourced.

124 "ABORT" skips unwanted channels.

132 "PLOTI" sets up plot area for a single plot on A4 sizepaper.

138 "PLOT2" sets tip plot area for a double plot on A4 sizepaper.

148 "PLOT3" sets up plot area for a single plot on A3 sizepaper.

154 "PLOT4" sets up plot area for four plots on A3 sizepaper.

171 "SET LIMITS" determines upper bounds for pressure andtime scales for plotting purposes. Also determinesmajor and minor tick intervals for plot axes, andlabelling frequency.

Appendix II

186 0.01 msec is the minimum acquisition interval of theBiomation 1015. The user is given the option, in thiscase, of examining the first 400 or 500 points in moredet a I .

193 "BOX" is a routine that frames the plot area and setsaside labelling areas.

197 "WARNING" issues cautions during certain errorconditions.

203 "CENTRE" places titles centrally on print tape andunderlines where necessary.

USER NOTES FOR PROGRAM "9825DL"

This program is essentially similar to "9825B1". Areas in which imiportantiiftterences occur are' note(.

Line Numbei Comments

4 Pressure array has to accommodate 4096 points, ratherthan 1024.

27,28 The DL2800's timebase unit is microseconds, rather thanmilliseconds. These lines are designed to accommodatethis difference and to allow a common timebase -

milliseconds.

54 This subroutine reflects the use of a differentinterface (HP98034A). The data treatment is similar tothe previous program.

59 The reading of the end-of-data (EOD) sequence at the endof the acquisition cycle is essential to return theDL2800 to its quiescent state.

I SUMMARY OR ABSTRACT:(if this is security classified, the announcement of this report will be similarly classified l

A data acquisition and processing system for use in the gun ballisticranges of Propulsion Division, WSRL, is described. Adaptability andeconomy are achieved by the use of digital transient recorders interfacedto a Hewlett-Packard 9825A Desktop Computer. In one case, minor hardwarechanges were required. Flexible software has been developed, encoded inHewlett-Packard's "HPL" programming language. Full software details aregiven for reference by system users wishing to make modifications.
