SU964680A2 - Device for registering equipment idle time - Google Patents

Description

The invention relates to automation and computing, namely, time control devices intended for use in an operational control system for manufacturing in various districts of the national economy.

According to the main auth. No. 593226, a device for time tracking is simply known, containing sensors connected to the corresponding driver inputs, time counters are simple, total time counters are simple, and time counters are just for reasons, pulse generator, switch block and series-connected counter, the switch, the coincidence unit and the start-up unit, the output of which is connected to the input of the pulse generator, the output of which through the switch unit is connected to the time counters simply by For reasons, and the outputs of the formers are connected to the corresponding til counters.

However, the known device takes into account the total time simply without taking into account the number of idle equipment, i.e. when idle

one unit of equipment, or when idle at the same time. several units — in both cases, the total time counting counter simply records the time just for only one unit of equipment. B. At the same time as in production for an objective assessment of the state of the fleet of equipment and an objective determination

10 of its utilization factor, it is necessary to have total time data on equipment downtime, depending on the number of simultaneously idle equipment, i.e.

15 in machine hours.

An inaccurate accounting of total time simply happens because a shaper at idle time simultaneously several units of equipment issues only one impulse to a counter at a certain moment, and not several ,

The aim of the invention is to improve the accuracy of the device.

The goal is achieved by the fact that in the device for recording time 30, the equipment is simply a shaper, a frequency divider, the AND element, a shift register and a pulse generator, whose output is connected to the first input of the shift register and through the frequency divider with the first inputs of the AND elements, whose outputs connected to the second inputs of the shift register, the output of which is connected to the output of the imager, whose inputs are connected to the second inputs of the elements. The drawing shows a block diagram of the device. The device contains sensors 1, the number of which corresponds to the number of units of equipment, the elements of AND 2, the divider 3 frequencies, the shift register 4, the total time counting counter 5, the pulse generator 6, the former 7, the time counting counters 8 simply, start unit 9, generator 10 pulses, switch unit 11, time counters 12, or simply for reasons, counting unit 13, switch 14, coincidence element 15, driver 16, combining generator of 6 pulses, frequency divider 3, elements 2 and shift register 4. The pulse generator b, the divider 3 frequencies, the elements of AND 2, the shift register 4, the total time counting counter I5 is simple, and the time counting meters 12 are simply grouped into board 17, which is installed in the workplace of the workshop manager. The shaper 7, the time counters 8 are simple, the generator 10 pulses, the start block 9, the counting block 13, the switch 14, the coincidence element 15 and the switch block 11 structurally constitute the console 18 — input of information that is located on the workplace of the site master. Shaper7 is a counting generator and a coincidence circuit, at one of the inputs of which the potential of sensors 1 is fed, and to the second - a pulse from the generator of counting pulses. The device works as follows. When one or several units of equipment are idle, the potentials from the corresponding sensors 1 are fed to the corresponding inputs of the L 7 and to the inputs of the I 2 elements. The counting pulses from the shaper 7 arrive at the corresponding counters 8 of the time record simple. Stable frequency pulses are continuously fed from the generator 6 output to the splitter 3 frequency input and to the shift register 4 input. The division factor of the divider 3 frequency is constant and is equal to the number of pulses emitted by the pulse generator for a certain period of time (for example, per / 1 s). The frequency of the pulse generator 6 is chosen to be larger than the number of monitored equipment. Every second, a pulse is removed from the divider 3 frequency, which passes through the corresponding elements AND 2 to the bit inputs of the shift register 4, which will record the fact of just the corresponding equipment units. Subsequent pulses from the output of the generator 6 pulses carry out the transfer of information recorded by the shift register 4 into the total time counting counter 5 simply. Thus, the pulse from frequency divider 3 will be recorded in the number of cells of shift register 4, equal to the number of enabled sensors 1, i.e. the number of idle equipment. From the shift register 4, the number of pulses equal to the number of idle equipment, i.e. the total time will simply be recorded in machine tool hours (machine-minutes). After a second, shift register 4 is cleared and the operation of the circuit for recording the total time is simply repeated. At the same time, the signals simply arrive at the information input console 18. The master, having determined the cause simply, from the work post, by pressing the button, calls the specialist of the relevant auxiliary service to eliminate the cause. After elimination of the cause, the potential from sensor 1 is simply removed and the time count is simply stopped. The master sets his buttons on his workplace on the switch 14 by fixing the time counting on the counter 8, just the time just 7 on the switch block 11 closes the button corresponding to the number of the given cause and pressing the button of the start block 9 (not shown) starts the pulse generator 10. In this case, the pulses from the generator 10 pulses arrive through the block 11 of the switches to the meter 12, taking into account the time of the station, for reasons and to the input of the counting block 13, the pulses from the output go through the switch. 14 to match element 15. When the signals arriving from the switch 14 and from the outputs of the counting unit 13 coincide, the signal enters the start unit 9 from the outputs of the coincidence unit 15. In this case, the pulse generator 10 is turned off and the counting is stopped. The absence of complex nodes in the device greatly simplifies and reduces the cost of construction, and the possibility

using it autonomously allows using the device in small production workshops. In this case, the possibility of an error in the accounting of time is included simply for reasons.

The complete functional scheme of the proposed roi device allows one to vary the number of units of monitored equipment by increasing the sets of the device.
