Description
Technical field
The utility model relates to a kind of brush direct current generator failure detector circuit that has, and specifically, is a kind of brush direct current generator MCU fault detection system that has.
Background technology
Existing have the brush direct current generator that special failure detector circuit is not set, thus when motor move if break down, can only stop driver, then motor is disassembled, check the circuit connection of motor internal then one by one, so that find out failure cause.
MCU (Micro Controller Unit), Chinese is a micro-control unit, claim one chip microcomputer (SingleChipMicrocomputer) or single-chip microcomputer again, be with CPU, the RAM of computing machine, ROM, regularly number device and multiple I/O interface are integrated on a slice chip, form the computing machine of chip-scale, for doing various combination control in different application scenarios.
MCU has that volume is little, IO interface is simple, low in energy consumption, plurality of advantages such as benefit is big.Along with the advantage that the quick growth and the MCU itself of domestic electronics and information industry had, the application of MCU more and more widely.
The utility model content
The utility model purpose is to overcome existing technical deficiency, a kind of brush direct current generator MCU fault detection system that has is proposed, by the MCU failure detector circuit is set at motor internal, can demonstrate the reason that motor internal breaks down fast in time, solve prior motor detects the internal fault difficulty when breaking down problem up hill and dale.
The utility model is achieved through the following technical solutions, the utility model comprises: motor body, be provided with operation circuit in the motor body, also comprise current sensor, voltage sensor, electric resistance sensor, MCU, current sensor, voltage sensor and electric resistance sensor are connected in the interior operation circuit of motor body, current sensor, voltage sensor and electric resistance sensor link to each other with MCU respectively, and MCU connects pilot lamp.
Described MCU connects alarm.
Described pilot lamp comprises five.
Principle of work of the present utility model: the shared general supply of MCU failure detector circuit and motor, when opening the motor switch electric motor starting, the MCU failure detector circuit is also started working simultaneously.Current sensor, voltage sensor, electric resistance sensor are connected in each operation circuit of motor internal, can constantly the electric current in the circuit, voltage, load signal be passed to MCU, the MCU standard value signal of voltage, load (in advance can the storaging current), the various signals that receive are carried out analyzing and processing, and compare with the respective signal of motor internal storage, the signal that receives as MCU and the signal of its storage inside are not simultaneously, MCU can control pilot lamp by the rule light on and off that set in advance, controls alarm simultaneously and sends alerting signal.What just can judge very soon that motor takes place by the demonstration situation of alerting signal and pilot lamp is any fault, takes corresponding treatment measures then.
Beneficial effect: the utility model has brush direct current generator MCU fault detection system, utilize the sensor that connects in the line that signal is passed to MCU, MCU carries out analyzing and processing to the various signals that receive, the signal that receives as MCU and the signal of its storage inside are not simultaneously, MCU can control pilot lamp light on and off according to certain rules, to control alarm simultaneously and send alerting signal. the utility model is simple to operate, high efficiency, making, easy to maintenance, operation gets up more economical, solved prior motor detects the internal fault difficulty when breaking down problem.
