(54) DEVICE FOR CONTROL OF WORK AND SIMPLE EQUIPMENT

one

This invention relates to automation.

A device for controlling operation and simply equipping} and containing output sensors, sensors of simple equipment connected to an information transfer unit connected to a software unit, and directly and through a control panel to the recording corner and the display are known. However, the operation of the known device is not reliable enough.

The proposed device is characterized in that serially connected nodes of the current state of the equipment, a matching element and a node of the preceding equipment state are inputted into it, with one of the inputs of the matching element being connected to the program block and the information transfer block.

In addition, the current equipment status node contains a memory block, which is connected to another input of the matching element, and an analyzer, the inputs of which are connected to output sensors and a program block. Ma FIG. 1 is given a structural diagram of the device; in fig. 2 — current state node (Equipment.

i The device consists of a sensor 1 of the product output and sensors 2 reasons just I equipment. The inputs of the output sensors {outputs are connected to the unit 3 for determining changes in the equipment condition, which (CONSISTENT of the node 4 of the current equipment condition, the node 5 of the previous condition of the equipment and the coincidence element 6, the output of which is connected to the information transfer unit 7 consisting of block 8 I switching, polling block 9, clock generator 1O, synchronizer 11, prop unit 12 of registering node 113, consisting of control blocks 14, electrically controlled typewriter 15 and tape punch 16, scoreboard 17 you ( va services call auxiliary board 18 (-negative services, remote control 19, consisting of a board-Mnemonic-circuit 20, a digital display unit 21, the control panel 22

Node 4 (see Fig. 2) of the current state of equipment consists of analyzers 123, the number of which is equal to the number of monitored equipment units and the memory block 24 Element: coincidence 6 consists of two groups of coincidence circuits, one of which serves to determine the moment of violation technological cycle of equipment operation, and the second - the moment of restarting equipment to normal | operating mode after troubleshooting. The device works in real time. Minute signals from the clock network are received at its input, which are summed up in the software block 12, which ensures the output of the current time through the switching unit 8 to the digital display unit 21. Information about the release comes from the sensors of output 1 to the input of the node of the current state of the equipment 4 (see Figs. 1 and 2). At the same time, clocking signals, determined by the technological tact of manufacturing products, arrive at the same node from software block 12; on controlled equipment. The clock signals act on the node analyzing the state of the equipment so that the first signal that comes after the output pulse from sensor 1 sets it to the position corresponding to the moment of the end of production and the second signal is needed to generate the signal simply and stored in the memory register ti. Thus, the Simple state for each monitored unit will be in the event that between the two clock signals of the program block does not receive an output signal from the sensors 1, otherwise the status will be Work. The signals from the output of the program block of entry with a period of 0.1 hour to the match element 6 request it for changes during the control period, while the match element 6 compares the status codes coming from the nodes of the current 4 and the previous 5 equipment. At the output of the coincidence element 6, a signal appears if at the time of polling by the prog ram 12 the code of the status of any unit defined by node 4 does not correspond to the code of the previous step) recorded at node 5. With the same signal 5, which is a block the memory of the equipment status codes during the polling cycle is set to the position corresponding to the new state of the equipment. When a signal from the output of the coincidence element 6 appears, pulses of this generator 10 are passed to the input of the polling unit 9, which reads the current time of day fixed in the synchronizer 11, and Ji follows an interrogation of the causes of downtime from the causes of the downtime 2 Utsii 8 and the control unit 14 on the printing maschinka 15 and the tape punch 16. In the case of just any controlled piece of equipment through the switching unit 8 on the control panel 2O of the control panel 19, a signal about Growth of the monitored unit: on the workshop service call panel 17, designed to speed up the call of auxiliary service workers (for example, mechanic, electrician, service technician, etc.) to the place simply, if they are directly in the workshop, the equipment group number is displayed, where idle equipment is installed, in the corresponding service of the auxiliary services call panel 18, lights and sound alarms are turned on. The cause signal is also simply fed to the digital display unit 21. which, when selecting the appropriate piece of equipment on the control panel 22, provides an indication of the causes of just the selected unit 1 of the equipment. The formula is: 1. A device for controlling the operation and simple equipment, containing output sensors, sensors of simple reasons, connected to the information transfer unit connected to the programmable unit, and directly and through the control panel to the recording unit. to the node and to the scoreboard, which is based on the fact that, in order to increase the reliability of the device, it contains serially connected nodes of the current equipment condition, a matching element and a node of the previous equipment condition From the inputs of the match element, it is connected to the program block and the information transmission block. 2. The device according to claim 1, characterized in that the current equipment state node comprises a memory block connected to another input of the coincidence element, and an analyzer whose inputs are connected to the output sensors and to the program block.
