PROGRAMMED MICROPROCESSOR SYSTEM THAT CONTROLS THE PARAMETERS OF THE OBJECT AND CONTROLS OPERATION
Abstract: In this work, the issue of "Designing a generator device using a modern microprocessor" is considered. Modern microprocessors AD9850, which are widely used today, were used during the design, and information about microcontrollers and controllers and their programming languages is presented. The principle and structural schemes of the designed generator have been developed.
Key words: Microprocessor systems, technique, product quality, automatic device, scheme, automatic mode, regulator, valve.
1. Introduction. The greatest achievement of microelectronics and computer technology is the creation of microprocessors, microcontrollers (large integrated circuits (CIS) with microprocessors).
Microprocessors (MP), microcontrollers (MK) are extremely small in size and have high computing and logic capabilities. EHM based on them, their low cost and high stability have expanded the use of digital computing devices in the unlimited sphere, and microprocessors control, manage and process digital devices based on microEHM. made it possible to create devices and systems.
Figure 1. Optimum design of MP measuring device
The following algorithm should be used to determine what logic to prepare the MP measuring and control equipment (Fig. 2).
construction of the measuring and control device.
From this algorithm, it is possible to know the necessary conditions for setting up measuring devices in "hard" or flexible logic. For example, in order to create devices in solid logic, the following conditions must be met: tasks to be performed should be very few; that the input/output device has one channel; if high speed is required; if the system performs one task (function) in each specific case, and so on. The achievement of using a microprocessor is realized only if the following conditions are true:
S if it is envisaged to further modernize the system by using program methods;
S if it is required to enter some data;
S if it happens that actions need to be performed many times and al-In order to correctly allocate a microprocessor, it is necessary to create a program that evaluates it. Therefore, it is advisable to use MP with low speed. In addition to the above descriptions, the following should be taken into account when choosing an MP:
The number of commands (determines the flexibility of MP application); S the number of registers (determines the calculation ability of MP); S addressing to memory capacity (MP data high S described in terms of processing at the border); S apply MP with the least number of voltages relative (MP S reduces the cost, simplifies the system structure); S the possibility of temporary stopping (characterized by the possibility of working MP in multiprogram mode);
The structure and main characteristics of MP are characterized by the following, convenient arrangement of K580VM80 MP buses, possibility of
connection with various external devices, provision of advanced program system, possibility of performing arithmetic operations in binary-decimal codes.
It is desirable to use K589 series MP in high-speed measuring and control devices. It is better to use K587, K588 series MP, which consumes less power in autonomous measurement, control devices. In measuring devices and systems, in addition to individual MPs, a universal microphone - roEHM is widely used ("Elektronik-S5", "Elektronik-60", "Elektronik-031", "VEF-Ormika", "SM-1800", "Elektronik-K1 -20, K1 - 10", "Electronics MS-2N0", etc.).
Control of the operation of the managed object is carried out as follows: Launching an automated control microcontroller device. The automated control and management device built on the basis of the controller is activated via the keyboard, and the controller begins to control the operation of the controlled object based on the program written in the PPZU (REPZU) memory chips.
Figure 3. Control and management of the operation of the object.
The states of the working bodies of the controlled object or other analog, digital messages are sent from the outputs 1,2,...,n of the object to the inputs of the B1, B2,...,Bm blocks. If the monitored parameters are continuous, they are supplied to the indicated inputs of the analog multiplexer (AM) through blocks B1, B2,...,Bi. It transfers the continuous messages given to the input of the analog multiplexer to the output through the control code given to the input of the controller (based on the controlled program) and transmits this analog signal to the input of the ATsP. ATsP converts this message into parallel binary code and forwards it to one of the controller's I/O ports. If the signals at the outputs of the controlled object are digital, then these signals are supplied from the outputs of the Bn,...,Bm blocks directly to the bit inputs of the I/O ports of the controller. The controller receives the messages sent to the input in turn based on the program and writes the processed results to the RAM device, if necessary, outputs it to the display.
Conclusion: In order to control the operation of the controlled object, i.e. to push the manipulator's hands to the left and right, pick up and put down the object, based on the messages received from the sensors, the controller generates control signals for controlling the mechanism (engine) that controls the manipulator's hands through the second input/output port. These control signals are sent to the BB1, BB2,...,BBn control unit through electronic switches EK1,
EK2,...,EK8, and from their outputs BM1, BM2,..., BMm8 start control mechanisms. The operator can start and stop the controller through the keyboard block, select (set) operating modes, control the program execution through the display, and perform similar tasks.
