Description

A kind of power-equipment control system

Technical field

The utility model belongs to control system, is applicable to the control of different industries medium power equipment.

Background technology

General power-equipment control realizes by common electrical elements such as buttons, signal may be introduced PLC in comparatively complicated place and realize computer control, field bus device generally only signal collection and transmission in power-equipment control is not used as Long-distance Control.

The utility model content

The purpose of this utility model provides a kind of power-equipment control system, to solve the problem of existing field bus device no Long-distance Control in power-equipment control.

A kind of power-equipment control system of the utility model comprises the on-site manual control loop, ac contactor coil, the A.C. contactor main contact, bus apparatus, the A.C. contactor auxiliary contact, upper display operation computing machine, first industrial network, second industrial network, the next Programmable Logic Controller, bus apparatus comprises fault jumping car output channel and programmed control output channel, described A.C. contactor main contact is connected with bus apparatus and power-equipment, connect with ac contactor coil and with fault jumping car output channel after described on-site manual control loop and the parallel connection of programmed control output channel, described upper display operation links to each other with the next Programmable Logic Controller by first industrial network with computing machine, and described the next Programmable Logic Controller links to each other with bus apparatus by second industrial network.

The utility model can combine field bus device and PLC and carries out the Long-distance Control power-equipment.The utility model has the advantages that: 1, operation circuit is simple, can use traditional scene-computer control principle, but bus apparatus is installed in the power distribution cabinet, only needing a netting twine to be about to all bus apparatus links to each other with host computer, need not lay a large amount of Long-distance Control cables, not take the input-output channel of PLC; 2, can finish the monitoring function of power-equipment operational process; 3, the later stage expand convenient: adopt this control system, in some does not need the equipment of Long-distance Control, can control not added host computer procedure, only show; But do not needing Long-distance Control originally, the later stage does not need cable laying again because the variation of operating mode need add Long-distance Control the time, only needs to revise a upper program and gets final product.

The Reference numeral implication is as follows: on-site manual control loop (1), ac contactor coil (2), A.C. contactor main contact (3), bus apparatus (4), fault is jumped car output channel (5), programmed control output channel (6), A.C. contactor auxiliary contact (7), upper display operation computing machine (8), first industrial network (9), second industrial network (11), the next Programmable Logic Controller (10), safety switch (12), stop button (13), start button (14), A.C. contactor second auxiliary contact (15), first contact (21), second contact (22), when the 3rd contact (23), the 4th contact (24).

Embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

A kind of power-equipment control system ,Comprise on-site manual control loop 1, ac contactor coil 2, A.C. contactor main contact 3, bus apparatus 4, A.C. contactor auxiliary contact 7, upper display operation computing machine 8, first industrial network 9, second industrial network 11, the next Programmable Logic Controller 10, bus apparatus 4 comprises fault jumping car output channel 5 and programmed control output channel 6, described A.C. contactor main contact 3 is connected with bus apparatus 4 and power-equipment 16, connect with ac contactor coil 2 and with fault jumping car output channel 5 in described on-site manual control loop 1 and programmed control output channel 6 backs in parallel, described upper display operation links to each other with the next Programmable Logic Controller 10 by first industrial network 9 with computing machine 8, and described the next Programmable Logic Controller 10 links to each other with bus apparatus 4 by second industrial network 11.Described bus apparatus 4 is parallel with A.C. contactor auxiliary contact 7.Be provided with safety switch 12 in the described on-site manual control loop 1, described safety switch 12 is connected with stop button 13 and start button 14.

The function of bus apparatus 4 is: 1. electric current, the running status of gathering power-equipment make it finally be presented at upper display operation with on the computing machine 8; 2. finish upper display operation and open, stop the power-equipment function with what computing machine 8 sent, 3. finish the failure protection function of power-equipment.

Programmed control output channel 6 is used for receiving and finishing the order of opening, stopping power-equipment that upper display operation sends with computing machine 8.The effect that fault is jumped car output channel 5 is: through gathering, calculate, analyze the current conditions to power-equipment, judge the running status of power-equipment, ground connection, overload, lacuna occur, send stop sign during fault such as imbalance mutually when calculating power-equipment, make ac contactor coil 2 dead electricity, thereby A.C. contactor main contact 3 is disconnected, cut off the power-equipment power supply.
