Description

I

The invention relates to telemechanics and is intended to collect information from dispersed objects,

Telemechanical devices with time division of communication channels are known, consisting of a dispatching set and controlled points on distributors, encoders, indicators, receivers and transmitters, interrogating cyclically controlled points. The cycle of operation of such devices is divided into temporary positions reserved for interviewing one controlled item. The time position for polling one monitored item, in the BCC, the queue is divided into two parts: one for transmitting the number of the polled controlled item, the second for receiving information transmitted from the controlled item. After switching on the device, the dispatching kit generates the number of the first controlled point and sends it to the communication channel. If the received number matches the number set for this monitor.

point, the controlled point provides response information received by the dispatching set of the device. At the moment when the response information is received, the number of the next control point is generated and it is polled. After the end of the last monitored point survey, the number of the first point under control is generated and the poll number is repeated DLJ.

Of the known devices, the dispatching set of the telemechanical device is closest to the invention, containing a pulse generator connected to the first pulse distributor, the last output of which is connected to the first input of the OR element, the output of which is connected to the input of the second pulse distributor, the outputs of which are connected to the first inputs of the block of formation of numbers of controlled items and the block of decoding and reproduction of information, to the second inputs of which are connected Exit first distributor pulses output generating controlled points room unit via a transmitter connected to the communication channel connected through a receiver to a corresponding row WMOs decryption unit and reproducing information {2. In the known dispatching set of the telemechanical device, the polling time of the monitored points is not aa depends on the time intervals between the information on the individual check points. If the time between changes in the value of a parameter or characteristic transmitted by the controlled point exceeds the time of the cycle of polling of the controlled points, then after transmitting the information from the counter item in subsequent cycles, a survey of this controlled item does not provide new information. The aim of the invention is to improve the speed of the telemechanical device. This is achieved by introducing into the Chersky dispatch a set of an AND element, an AND-OR element, delaying elements, RS flip-flops and pulse shapers, whose inputs are connected to the outputs of the second pulse distributor, the outputs are connected to the first inputs of the AND-OR element the input of the OR element, the outputs of the second pulse distributor and the output of the decryption and information playback unit are connected respectively with the first and second inputs of the AND element, whose outputs are connected to the S inputs JR-S e whose outputs are connected to the second inputs of the element k through the corresponding delay element with its R inputs. The drawing shows a structural diagram of the dispatching set of a telemechanical device. The dispatching set of the telemechanic device contains a pulse generator 1, the first pulse distributor 2, the element OR 3, the element 4, the block 5 of forming the number of controlled points, the second pulse distributor 6, the R-S triggers p the transmitter 8, the receiver 9, the pulse formers 10 | lOf, block 11 decryption in reproducing information, delay elements 12 | - 12, element AND-OR 13, communication channel 14 63 4J The device works as follows. The pulses from the output of the generator 1 are fed to the input of the distributor 2 and form temporary positions for transmitting the numbers of controlled points and receiving information from the controlled points. After testing one cycle by valve 2, the signal from its last output through the element OR 3 valve 6 is transferred to the next position, forming a temporary position for polling the next controlled point. The signals from the outputs of the distributors 2 and 6 are fed to the number forming block of the controlled points 5, which forms the corresponding code and using the transmitter 8 transmits the code to the communication channel 14o The transmitted code is received at all the controlled points and one of them, whose number corresponds to the received code , provides response information received through the communication channel 14 to the input of the receiver 9 and from the output of the latter to the input of the block 11 for decrypting and reproducing information. In block 11, the received code is analyzed and, if from the polled controlled point of posting the information, then a signal appears at the output of the block which, through the answer of the most recent element AND 4, converts to one state one of the triggers number of the polled controlled item. Assume that the monitored item Me 2 was polled, then the trigger 72 is transferred to the single state. The signal from the single output of the trigger 7 opens the second element AND AND OR 13 and starts the delay element 122. The delay time of the element 12 is equal to the minimum possible interval between information on monitored item 2. If this time is longer than the polling cycle time of all monitored items, then in the next polling cycle, trigger 7g is in one state and the appearance of siphl the second outlet of the distributor 6, the momentum generated by generator 10, passes through the second element and I-OR gate 13 to the input of OR 3 and carries the distributor 6 to the next position, thus will vyzyvat1k: after the first paragraph immediately third controlled. This position will remain until the end of the delay time of the element 122. The moment the end of the delay occurs, the signal from the output of the element 12 brings the trigger 72i to the zero state of the second element AND AND-NLI 13 closed and the controlled item No. 2 enters the polling cycle. If during the polling of the monitored item no information is received, then at the output of the block 11 for decoding and reproducing information the signal does not appear and the trigger (one of the triggers), the number of which coincides with the number of the called controlled point, will remain in the zero state. An exception to the polling cycle of a controlled item will not occur. The introduction of pulse shapers, an AND-OR element, an AND element, an R-.S trigger, and a delay element distinguishes the proposed device from the known ones, since it allows reducing the polling cycle of controlled points due to the temporary exclusion of individual controlled points and thereby speeding up telemechanical device.
