At present, be used for the control circuit of driving motor running because designed lines is complicated, select element more, in case break down, often needing the technician to expend the long period looking up the fault is also keeped in repair, this not only makes the maintenance personal feel inconvenience deeply, also greatly affected for the production of in the work efficiency of motor, reduced productivity effect.And to improve the maintenance speed of motor, and just must reduce the troubleshooting time, this just needs directly to find fast fault; In addition, the fault that many circuit for controlling motor occur can be damaged motor directly or indirectly, and serious meeting damages motor, causes motor to use.
Summary of the invention
For the demand; the invention provides a kind of accident warning device that detects motor control unit; this accident warning device is reasonable in design, circuit is simple; adopt multichannel modularization detection alarm technology; can detect in real time each road fault that motor control unit occurs, and the alarm indication abort situation, simultaneously stall motor; not only make things convenient for people's maintenance but also well protected motor, had higher using value.
The present invention is a kind of accident warning device that detects motor control unit, this accident warning device comprises circuit for controlling motor and failure alarm circuit, described circuit for controlling motor can be divided into several control Subcircuits modules, described failure alarm circuit comprises several signal detection modules, logic control circuit module, signal lamp, hummer and power supply, and described signal detection module links to each other with the Electric Machine Control Subcircuits module respectively.
In a preferred embodiment of the present invention, described signal detection module is comprised of sensor and A/D converter, when some Electric Machine Control Subcircuits modules break down, the signal detection module that is attached thereto at first detects fault-signal by sensor, by sensor fault-signal is sent into A/D converter conversion again, at last by A/D converter output digit signals " 0 ".
In a preferred embodiment of the present invention, described Logic control module is comprised of not gate or door, resistor, diode, triode and relay.
In a preferred embodiment of the present invention, described signal lamp is the LED electroluminescent lamp of several different colours, and it is connected with corresponding signal detection module respectively, and when signal detection module output digit signals " 0 ", corresponding signal lamp is lighted.
In a preferred embodiment of the present invention, the initial output state of described signal detection module is " 1 ", and the signal lamp in the failure alarm circuit is for extinguishing state at this moment, and hummer is noiseless, and motor runs well; When a certain road or measurement of multipoint signals module output state were " 0 ", hummer sent alarm sound, and motor is shut down by Control simultaneously.
The present invention has disclosed a kind of accident warning device that detects motor control unit; this accident warning device is reasonable in design, circuit is simple; adopt multichannel modularization detection alarm technology; can detect in real time each road fault that motor control unit occurs; and alarm indication abort situation; simultaneously stall motor has not only made things convenient for people's maintenance but also has well protected motor, has higher using value.
Description of drawings
Fig. 1 is the circuit theory diagrams that the embodiment of the invention detects the motor control unit accident warning device.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
Fig. 1 is the circuit theory diagrams that the embodiment of the invention detects the motor control unit accident warning device; This accident warning device comprises circuit for controlling motor and failure alarm circuit, described circuit for controlling motor can be divided into several control Subcircuits modules, described failure alarm circuit comprises several signal detection modules, logic control circuit module, signal lamp, hummer and power supply, and described signal detection module links to each other with the Electric Machine Control Subcircuits module respectively.
The signal detection module of the accident warning device that the present invention mentions is comprised of sensor and A/D converter, when some Electric Machine Control Subcircuits modules break down, the signal detection module that is attached thereto at first detects fault-signal by sensor, by sensor fault-signal is sent into A/D converter conversion again, at last by A/D converter output digit signals " 0 "; The signal lamp of this accident warning device has been selected the LED electroluminescent lamp of the different colours such as red, yellow, blue, green, white, it is connected with corresponding signal detection module respectively, when signal detection module output digit signals " 0 ", corresponding signal lamp is lighted, which the Electric Machine Control submodule that breaks down as can be known by the signal lamp of lighting is, the technician can keep in repair accordingly fast, has so just greatly saved servicing time, has improved efficient; In addition, the Logic control module in the failure alarm circuit is comprised of not gate or door, resistor, diode, triode and relay, and whole failure alarm circuit provides DC voltage by+12V battery pack.
The initial output state of signal detection module in this failure alarm circuit is " 1 ", and this moment, motor ran well, and the signal lamp in the accident warning device all is to extinguish state, and hummer is noiseless; When A1 road or A1 road and A2 road signal detection module output state were " 0 ", signal lamp L1 and L2 obtained status input signal and are " 1 ", i.e. high level signal begins to light and sends ruddiness and gold-tinted; At this moment, the digital signal " 0 " that triode T1 receives or door and not gate are exported, namely low level signal is in cut-off state, and relay K A disconnects immediately, stops motor operation; In addition, the digital signal " 1 " that triode T2 receives or door is exported, namely high level signal is in conducting state, and hummer B switches on immediately and sends alarm sound; The maintenance personal can overhaul fast according to chimes of doom and signal lamp state, and simultaneously, motor has obtained to greatest extent protection because damaging can not appear in time stall.
The present invention has disclosed a kind of accident warning device that detects motor control unit; this accident warning device is reasonable in design, circuit is simple; adopt multichannel modularization detection alarm technology; can detect in real time each road fault that motor control unit occurs; and alarm indication abort situation; simultaneously stall motor has not only made things convenient for people's maintenance but also has well protected motor, has higher using value.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
