Description

The invention relates to information and measuring technology and telemechanics.

The aim of the invention is to improve the speed and expansion of the field, the use of the device

The drawing shows the proposed telemechanical device.

The device contains a linear unit 1, a synchronization unit 2, a generator 3, a distributor 4, a transmitter 5, a block 6 for selecting a controlled item j, a receiver 7, an arithmetic unit 8, a random access memory unit 9, a reprogrammable storage unit 10, a unit for comparison, switch 12, execution units 13, line 14.

The device works in two modes.

Mode 1. This mode is local and is executed without interference from the control point. After the initial start-up, block 12 permits block 8 to read the program from block 10. In accordance with the program, block B issues the address and command to blocks 13 and receives information about the execution of the command from them. The block 8 processes the received information in accordance with the program recorded in block 10, makes a decision and writes the results into block 9. If necessary, block 8 issues an adjustment command to the corresponding block 13 if the monitored parameter has exceeded the norm.

Mode 2. Receive command from control point. The serial information from the communication line 14 through the linear block 1 enters the block 2, which feeds the signal to start the distributor 4 and, through its cycles, the information enters the block 6, which feeds the enabling signal to the receiver 7 to receive information from block 1. Depending on Priority unit 8 receives the received information and permits the transmitter 5 to issue a receipt of information through unit 1 to the communication line 14.

With the right information, there may be two cases.

1) An array of information accumulated in block 9, characterizing the parameters of a co-controlling object, is required. At the same time, unit 8 allocates to the transmitter 5 the first words of the information array. The transmitter 5 starts the distributor 4 and sends information to the line 14 via block I. After transmitting the first word, he reports this to block 8, receives the next word from the array of information from him, and repeats the transmission cycle. At the end of the array, a receipt for the end of the array of information is transmitted to the line.

2) Measurement of the monitored parameter or command execution is required. Now, block 8 selects the corresponding block 13 according to the program recorded in block 10, performs the measurement and transmits the results to transmitter 5, which starts distributor 4 and sequentially outputs information via block 1 to communication line 14.
