SYSTEM DEVICE

one

The invention relates to automation and computer technology and is intended for use in local and hierarchical shop automation production control systems.

Communication devices with an object are known for a workshop production control system (CCI), comprising a local control unit connected to the input / output buses in the computer; an analog control unit, the outputs of which are connected to the analog control object; code control block whose outputs are connected to the code control object; block of input of discrete information, the inputs of which are connected to the console of the operator of the shop system.

The known devices are characterized by complexity and bulkiness, which reduces the reliability of control of the object.

The proposed device does not have these drawbacks and differs from the known ones in that it introduces an analog reference block, an address block, a code command block and a memory block, and the control and local outputs of the control block are connected to the analog control block, the analog reference block, the memory unit, the code command block and the code control block, the information outputs of the local control block are connected to the analog reference block and the code command block, the information outputs of the analog reference block are connected to the en block tax control, the address outputs of the analog reference block are connected to the first address block, the outputs of which are connected to the address buses of the analog control object, and the operator’s console of the shop system are connected to the inputs of the first address block, the code control block outputs are connected to the code control block, the block outputs code commands are connected to the second block of the address, the outputs of which are connected to the address cords of the code control object, and an operator console is connected to the inputs of the second block of the address guild system, outputs the input block of discrete data podklyuchenEz to the block memory, and outputs the block memory - a local unit upravlepi.

The drawing shows a block diagram of the proposed device.

The device consists of the following functional blocks: discrete information input unit 1, first address block 2, memory block 3, second address block 4, analog control unit 5, analog reference block b, local control unit 7, communication unit with a MEETING OBJECT PRODUCTION MANAGEMENT. .i / i uriisi tfll) :)

code commands 8, code control block 9.

Through the local control unit 7, control and service information is exchanged between the computer (VM) and the DCO blocks according to the communication algorithm laid down in the automated system. In addition, the unit 7 controls the operation of the analog control units 5, the analog tasks 6, the code commands 8, the code control 9 and the memory 3.

In block 6, the analog reference codes and their addresses received from the local control unit 7 are stored. In addition, in block 6, the addresses of the analog reference values are decrypted into two-step signals to turn on or off the corresponding analog control objects or to allow input of analog references to the corresponding contours regulation.

The accuracy of the digital-to-analog conversion in the device is no more than one percent, which fully satisfies the requirements for control channels from the VM in the workshop production control systems.

The first address block 2 stores the address signals of analog tasks received from the analog tasks block 6 and is outputted to the corresponding control circuits only after the input of the resolution signal from the operator console. In this case, depending on the operation of a particular control loop selected by the operator, in the first block of addresses 2, either the enable signal is memorized, or its reception and deletion is performed.

In the automatic control mode, the control loop will receive the address signal accompanying the new analog reference signal from the analog control block 5 automatically regardless of the operator, and in the semi-automatic control mode it will receive only the operator permission each time.

The discrete information input unit 1 receives two-position signals from the operator's console, which are signals of commands input from the operator's console to the VM. This block matches the input signals with the DCO signals and outputs the matched signals to memory block 3. All inputs to block 1 are initiative.

The storage unit 3 is used to encode two-step signals received from the discrete information input unit, memorizing the codes and features of the discrete information and outputting them via the local control unit 7 in the VM. In the code control unit 9, the code control signals in parallel binary code received from the VM through the local control unit are stored, amplified and output to the control object.

In the code command block 8, the addresses of the code control commands are stored, two-position signals are decoded and output to the second address block 4.

The second block of addresses stores the addresses of the code control commands and issues them to the control object after the permission signal from the operator console arrives at the block.

With the automatic control of the object from the VM in block 4, the permission signals are stored, and in the future the address signals to the control object will be received independently of the operator, accompanying the corresponding code control signals. With semi-automatic control, address signals are sent to the control object only with the permission of the operator
