Agrosystem
It was manufactured from 1984 by JZD AK Slušovice. Hardware is based on U880D @ 2,5MHz.Operating system running on the computer: COBRA/W.
A computer very similar to TNS SC, used with OS Cobra. Usually in TNS SL64 or TNS A02 (manufacturer Blansko, RO2-220V-200VA-50Hz).
Briefly can be defined by an agrosystem as "a heterogeneous computing system designed for decentralized management of agricultural enterprises." As the name implies, the main objective was to provide agricultural companies by a powerful yet economically acceptable means of computer technology for highly decentralized, effective forms of use of computer technology at the company level, ev. the race.
The agrosystem has already been conceived as a comprehensive computer network, so not as an autonomous microcomputer.
The basic principles of the computer network are: connection, massiveness, scattered intelligence, data aggregation, data collection, data protection; building kit.
The principle of connection is one of the basic and decisive principles. It is realized by technical and logical interconnection of network elements.
- Own line connection inside the company (building complex, etc.),
- Public telephone network,
- signal converter (eg MDS 1200), telephone device,
- Module Automatic Phone Options (AVT),
- Assad interface module (for connection between different systems), ASK (for connection between TNS computers),
- computer TNS-64 K (concentrator),
- MULTIPLEXOR ADEC (for connecting computers of TNS and EC series computers),
- UNIPP Universal data transfer unit "Off-line" (replaces the sensor and perforated punch tape).
The program means of connection are realized by a communication protocol in TNS control programs. The ISO 1745 communication protocol used is implemented under the name BCS-TNS.
Hardware
The core of the system consists of a basic upgraded assembly of the microcomputer TNS-64, consisting of modules:
CPU, INT, DRAM 64K, PROM, KBD-TVD, FLP, UVI and ASK.
Currently, system software can be divided into two groups:
- COBRA operating system
- DELAS Operational System
- Sbasic
is an interpretation of the Basic language. The Cobra system has the advantage that it does not need a system medium. The brief characteristics of Sbasic is:
- Store programs on the KPP800 cassette unit, black tape, in the future.
- Data storage on the KPP800 cassette unit, black tape, in the future.
- Definition of numbers: integer in a fixed line (2 byte), simple accuracy in the floating line (4 byte), double accuracy in the floating line (8 byte).
- Access to I/O Gateway at Basic level.
- Display I/O Gate Definition directly in Print and Select Security Type (interruption, control sum).
- Possibility to insert multiple commands into one line.
- Powerful line editor.
New versions of SBASIC are focused on driving technological processes. They are characterized by new commands and functions that are used to work with A/D converter and with real -time clock. New commands and functions are:
- ADC K - a function whose value is a/d convert. K is the channel number.
- Tim n - a function whose value is instant time - hours, minutes, seconds or dozens of milliseconds.
- Stim - Real Time setting command.
Delas
Delas is a system for developing programs in JSA. It includes a text editor, a relative assembler, a relative introduction and program equipment for tuning programs. System media for Delas are cassettes in KPP800 drives. The Delas system allows you to purchase source programs, translate and combine several relative programs into one absolute module. Source, relative and absolute programs can be kept on cassettes.
Program debug program equipment has commands for:
- Inserting programs from cassettes and storage on cassettes.
- Working with black tape.
- Modification and memory display.
- View and modify I/O Gate.
- Display of transmitted and comparison of memory blocks.
- View and modify memory blocks.
- Transfer and comparison of memory blocks.
- View and modify the registers.
- Set the point of stopping the tuned program.
- Starting the program.
- Stepping the program after individual instructions with displaying all registers, status, addresses only.
- Starting the machine program with tracing.
From the elements it was possible to create problem -oriented assemblies for:
- Social-economic calculations
- Operational management
- Scientific and Technical calculations
- Control of technological processes
The manufacturer's plan was assumed that these spheres were increasingly blending up to the stage, when a comprehensive hierarchically integrated system of management of the agricultural enterprise and the above -aged spheres.
In JZD Slušovice, all areas of the above applications were solved at that time, in terms of system analysis, technical equipment and software development. As an example, the wage and warehouse agenda, operational traffic management, nutrition and herd reproduction, agricultural statistics and direct technological processes (fermentation, large -capacity stables).
