In addition, existing Machine Tool Circuit on-off controller is mainly used in the fault generation of Machine Tool Circuit and the control of maintenance, this technology is when input certain fault number, the corresponding trouble spot of Machine Tool Circuit just disconnects, after the operator finds fault, as long as input corresponding fault number, system can connect this circuit, to recover fault.This controller has the following disadvantages: can only be according to the break-make of fault control circuit, in actual job, as long as measure the break-make of each branch road, again according to bug list, determine fault number, then input corresponding fault number, can connect circuit, this controller obviously can't be completed the matching judgment function of load and electric current.
Equally, control in the real training examination in the Machine Tool Circuit break-make, Machine Tool Circuit intelligent check device for answering question also has a fatal defective, in case i.e. fault number leakage, even the operator does not understand circuit theory at all, as long as key in corresponding fault number in input equipment, fault will be removed easily, can not realize the distribution control technology of students is checked and rated really.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of distribution branch road intelligence load governor is provided, make this distribution branch road intelligence load governor can be used as the support equipment of low-voltage power supply and distribution system, also can be used as simultaneously the upgraded product of Machine Tool Circuit intelligent check device for answering question.
The technical scheme that solves the problems of the technologies described above is: a kind of distribution branch road intelligence load governor, comprise control center, power supply unit, driver element, performance element, data input controller, warning and display unit, wherein,
Described control center is PLC control center, is used for parts are commanded, coordinate, organized and control, and the distribution of data input controller input is propped up circuit-switched data receives, judges, determines whether to connect the power supply of this distribution branch road;
Described power supply unit is used to PLC control center that power supply is provided, and the output terminal of this power supply unit is connected with the input end of PLC control center;
Described driver element is used for the control signal of PLC control center output is amplified, and carries out the instruction of PLC control center output to drive performance element, and the input end of this driver element is connected with the output terminal of PLC control center;
Described performance element is used for according to the instruction of PLC control center, the distribution branch road being carried out break-make to be controlled, and the input end of this performance element is connected with the output terminal of driver element;
Described data input controller is used to the operator that operation interface input data are provided, and with this data transmission to PLC control center, the output terminal of this data input controller is connected with the input end of PLC control center;
Described warning and display unit are used for the data of input error are reported to the police and shown, simultaneously alarm times are stored, and the input end of this warning and display unit is connected with the output terminal of PLC control center.
Further technical scheme of the present invention is: described driver element is transistor amplifier or driver circuits for integrated circuit.
Further technical scheme of the present invention is: described performance element is DC relay or solid-state relay.
Owing to adopting technique scheme, the present invention's distribution branch road intelligence load governor compared with prior art has following beneficial effect:
1. can be used as the support equipment of " intelligent type low-voltage is for distribution training system ":
The present invention by input distribution branch road power load power and calculate current value, the match control with electric current of loading, thus simulation realizes the selection training to wire and the switchgear of power supply-distribution system.The operator only has the specification of selecting wire and device for switching according to the power load size, and system is just connected to the load power supply, otherwise processes off state.Therefore, the present invention can be used as the support equipment of " intelligent type low-voltage is for distribution training system ", be conducive to the student according to the size of load, calculate and select suitable switch, the specification of wire, solved same wire from switchgear the simulation distribution problem in different using electricity systems, have real training economic benefit preferably.
2. can be used as the upgraded product of Machine Tool Circuit intelligent check device for answering question:
Adopt in the lathe maintenance practical teaching process of this distribution branch road intelligence load governor, remove a certain fault, need to be in input equipment the two or more measurement parameter of input fault element, through system's correct judgment, just removed fault.Therefore, the present invention can make the real training examination have more operability, solved preferably with guessing questions by sheer good luck or eavesdrop other people and overhauled the problem of achievement, can provide more fair, just technical support for all kinds of examinations and Skill Competition, can be used as the upgraded product of Machine Tool Circuit intelligent check device for answering question.
3. the misdata of input had automatic alarm and memory function:
In the training of project assignment, error appears if logarithm it is calculated that, be considered as misdata, system's meeting automatic alarm, and with the number of times automatic storage of reporting to the police, can be used as real one of the evaluating basis of achievement of doing with this.
4. can provide a physical platform for the real training of the professional skill of all kinds of vocational schools:
