Abstract
The utility model discloses a motor controller which comprises a current sensor, a voltage sensor, a current comparison detection module, a voltage comparison detection module, a processing module, a communication module, and a display and an alarm device which are connected to the communication module, wherein the current comparison detection module is connected with the current sensor and the processing module; the voltage comparison detection module is connected with the voltage sensor and the processing module; the processing module is connected with the communication module and is also connected to a motor relay; and the motor relay is connected with and controls a motor main loop. According to the motor controller provided by the utility model, the structure is simple; motor faults can be effectively and immediately found; a worker can conveniently find out a fault reason and can timely control a motor to be started or stopped.
Description
Technical field
The utility model relates to the electric machines control technology field, relates in particular to a kind of electric machine controller.
Background technology
At present, because developing rapidly of electronic technology, sensor technology, the communication technology and computer technology, electric machines control technology is thereupon development also, existing part electric machine controller diverse in function, but complex structure, the manufacturing cost that thereupon produces is also high, and too complicated circuit also can cause the malfunction elimination difficulty.Therefore, provide a kind of electric machine controller simple in structure, can be effectively and find timely electrical fault, and the convenient for maintaining personnel find out failure cause, and this is problem to be solved in the utility model.
The utility model content
The purpose of this utility model is, provides a kind of electric machine controller by the detection to electric current, voltage, can be effectively and find timely electrical fault, can in time control starting or stoping of motor.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of electric machine controller, it is characterized in that, comprise current sensor, voltage sensor, electric current contrast detection module, voltage-contrast detection module, processing module, communication module and the display and the alarm that are connected in communication module, described electric current contrast detection module connects current sensor, processing module, described voltage-contrast detection module connects voltage sensor, processing module, described processing module connects communication module, also be connected in motor relay, described motor relay connects and the control motor main circuit.
Further, described processing module is processor of single chip computer.
Further, described processing module can directly connect alarm.
Description of drawings
Fig. 1 is a kind of theory structure block diagram of electric machine controller.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of electric machine controller comprises current sensor, voltage sensor, electric current contrast detection module, voltage-contrast detection module, processing module, communication module and the display and the alarm that are connected in communication module.Electric current contrast detection module connects current sensor, processing module, and the voltage-contrast detection module connects voltage sensor, processing module, and described processing module is processor of single chip computer, and it connects communication module, also is connected in motor relay.Motor relay connects and the control motor main circuit.Processing module also can directly be connected with alarm.This electric machine controller is in operation, electric current is by the current sensor detection signal and be sent to electric current contrast detection module, pass through again the analysis of processing module, judge to have or not curent change to occur, can effectively prevent the infringement that the current breaks such as overcurrent, overload, short circuit produce; Voltage is by the voltage sensor senses signal and be sent to the voltage-contrast detection module, passes through the analysis of processing module again, judges to have or not change in voltage to occur, can prevent effectively that external voltage from changing the infringement that produces.After processing module is analyzed the signal that detects, the consequential signal that produces is sent to display by communication module, demonstrate correlation values on the display this moment, and display can have many to be located at the place of conveniently checking.When detecting signal when undesired, processing module sends command signal makes alarm send alarm bell, or makes the alarm of being located at the distant place send alarm bell by communication module, meanwhile, processing module sends a command signal to motor relay disconnects motor main circuit, and motor is out of service.
In sum, a kind of motor controller structure that the utility model provides is simple, can be effectively and find timely electrical fault, and the convenient for maintaining personnel find out failure cause, and can in time control starting or stoping of motor.
Above-described only is execution mode of the present utility model, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, and these all belong to protection range of the present utility model.
