Description

LINES (up to 0) and low frequency generator time intervals 3 (as is correct, equal to 1 / 6OHz), this task for a person is very difficult. When the control computer works in the process control mode, this one. the function is performed by the machine, which, however, requires a lot of machine time for polling the counters.

In addition, this device takes into account only the total time of the strip of glass, without taking into account the number of such line interruptions, which makes it difficult to calculate such an important technical and economic indicator, as the average time to restore the normal mode of operation of the production line, and, finally, the device in question does not provides operational control of its health, which reduces both hardware and functional reliability of the device, complicates troubleshooting.

The aim of the invention is to simplify the device and increase its reliability.

The goal is achieved by the fact that a control unit is entered into a device containing sensors, a time interval generator, a pulse converter, to one of whose outputs are connected time counters, the inputs and outputs of which are connected respectively to the outputs of the first input unit, the display unit and the control machine, OR-NOT elements, matches, counts of the number of violations of the mode and the second information input block, the outputs of which are connected to the first input of each counter, the number of violations of the mode, the other input of which Connected to the output of the corresponding even element of the match, which is connected to the first input of the corresponding element ORINE, the second input of which is connected to the output of the odd element of the match, the outputs of all the elements OR NOT, the outputs of the even elements of the match and the outputs of the information input blocks are connected to the corresponding indix block , one of the outputs of the control unit is connected to the corresponding inputs of the information input units, the input and output of which are connected to the corresponding computers via a control computer indication blocks and to one IZ.invhod of the control unit, the sensor outputs through the pulse converter and the time interval generator are connected to the input pulse converter, I

 The drawing is a diagram of the device for monitoring and recording the operation time and simple technological equipment.

The device contains sensors 1, l, 2, 2, 3, 3, time interval generator 4, converter imtyjibcoB 5, counters of the counted time 6-C (even - fighting time, odd - normal operation time), first block 12 of information input, control calculating machine 13, time taken indication block 14, decision violation indication block 15, matching circuits 16-21, elements OR NOT 22-24, display block. 25 simple, mode violation indication block 26, mode violation number indication counters 27 -29, the second unit for entering information into the machine 30, the contact unit roll 31.

The device works as follows. Pulse converter 5, the number of channels equal to the number of glass production lines in one unit (glass furnace), generates temporary pulses at the outputs determined by the information received from sensors 1, G 2, 2 3, 3. These pulses are taken into account by those of counters 6 -11, to which they are received, and then this information goes through the first input unit 12 to the controlled computing machine 13. The difference from the prototype is that the information on the operating time of the equipment, counted by counters 6-11, displays On the display unit 14 of the recorded time, connected to the input of the first block of input 12, this happens periodically upon a command issued by the machine 13, or at the request of the operator from the control unit .31, At the same time, the number of the machine from which information is received is displayed. At the same time, information on the time of normal operation, which is not of special value for the operator, is advisable to be displayed as little as possible on the display unit (only for the purpose of monitoring the operability of the corresponding channels),

In addition to information about the total time of the battle, information on the number of such violations is necessary for calculating the technical and environmental performance of the equipment. In order to take into account the number of disturbances in the normal operation of the equipment, counters 27-29 are entered into the device circuit, the outputs of which are connected via the second input block 30 to the control computer 13 and to the display unit 15 of the number of recorded violations. The inputs of counters 27-29 are connected to the outputs of even-numbered coincidence circuits 16-20, one input of each of which is connected to the generator of time intervals 1, and the other to the corresponding output of the pulse converter §. When at its output there appear pulses synchronous with the pulses of the time interval generator, the level of the output voltage of the corresponding CXSNW coincidence changes and information about the malfunction is recorded in one of the counters 27-29. In addition to counters, to the outputs

4th matching schemes connected

an indication unit 26 of a disturbance mode to which operational information about violations of the equipment’s operating mode is displayed. Odd-numbered match schemes 17-21 work similarly even, and the signals at their outputs indicate the normal operation of the equipment. The outputs of each pair (even and odd) of the coincidence circuits through the OR-NOT elements are connected to the display unit 25 simply, to which operational information about the simple equipment is output. Both blocks 25 and 26 are connected to the control computer, which allows for more efficient entry of relevant information into it, and the number of polling cycles by the meter machine is reduced to a minimum (up to one time per shift to record the meter readings in the long-term memory |) Control 31 is designed to periodically monitor the health of unused channels of the device. It contains the keys in the circuit between the sensors and the transmitter.

impulses that, when checked, are opened by a command from the machine (or manually) and ensure the appearance of output signals of checked channels if they are operational, in the absence of a response at the output of the checked signal in the report (or the latter’s fault is visually detected.

The use of a single indication unit of the time taken into account for the entire device can significantly reduce the volume of the equipment used in the device and the area it occupies on the front panel of the panel. This improves the operating conditions of the operator, as he is freed from the perception

large flow of redundant information Information (5 violations of the equipment operation mode and about it is simply displayed on special boards and simultaneously entered into the control computer. All this together simplifies the device and its operation and leads to significant

saving of computer time, since it allows minimizing the number of poll polls of counters. Accounting for the number of equipment malfunction will allow measures to be taken to improve its reliability and efficiency. The introduction of the control unit into the circuit of the device increases the reliability of the latter and, accordingly, the equipment it serves.
