Further improvement of the present invention is: also comprise the shutdown time delay module that is connected with the CPU puocessing module, it determines the moment that motor stops operating.
Further improvement of the present invention is: comprise also and shut down the shutdown Executive Module that time delay module is connected that it receives shuts down the stopping signal that time delay module is sent here, and motor is stopped operating.
Further improvement of the present invention is: described temperature detecting module comprises temperature transducer, input circlult and the A/D converter that is connected successively, described input circlult is converted into voltage signal to the output signal of temperature transducer, by A/D converter this voltage signal is converted to digital signal, and gives described CPU puocessing module.
A kind of controlling method of motor may further comprise the steps:
501, the water temperature in the temperature detecting module detection of engine water tank, and temperature signal exported to the CPU puocessing module;
502, the CPU puocessing module is handled this temperature signal, if the CPU puocessing module judges when this temperature signal is high water temperature that then output tripping operation control signal is given the tripping operation Executive Module; Otherwise, execution in step 501;
503, the tripping operation Executive Module is according to the tripping operation control signal that receives, the load of corresponding change motor.
Step 501 further comprises: the temperature signal of being given CPU puocessing module input water temperature by the water temperature alarm switch.
Step 501 further comprises: by temperature transducer the water temperature in the engine water tank is detected, by input circlult the output signal of temperature transducer is converted into voltage signal, by A/D converter this voltage signal is converted to digital signal, and exports to the CPU puocessing module.
Step 502 further comprises: if this temperature signal value is during greater than default temperature value, then the CPU puocessing module is judged as high water temperature, gives simultaneously to shut down time delay module output and shut down time delayed signal, determines the moment that motor stops operating.
Step 502 further comprises: when the moment that motor stops operating arrives, then shut down time delay module and give shutdown Executive Module output stopping signal, by the rotation of shutting down the Executive Module shutting engine down.
Step 503 further comprises: the tripping operation Executive Module all gets rid of engine load.
Owing to adopted above technological scheme, when the situation of high water temperature appears in motor, get rid of the load of motor is some or all of earlier, promptly, allow motor underloading or no-load running, after after a while, when internal engine temperature is relatively low or reach normal operating temperature substantially, motor is stopped operating, in the middle of this process, engine interior can access cooling, thereby has reduced the difference of motor inside and outside contraction ratio, avoid embracing the cylinder accident and occur, prolonged the working life of motor.

[embodiment]
Below in conjunction with drawings and Examples the present invention is further set forth:
As shown in Figure 1, a kind of engine controller comprises temperature detecting module, CPU puocessing module, and tripping operation Executive Module, shutdown time delay module and shutdown Executive Module are temperature detecting module in the frame of broken lines among the figure; Wherein, temperature detecting module, tripping operation Executive Module and shutdown time delay module all are connected with the CPU puocessing module respectively, shut down time delay module and are connected with the shutdown Executive Module.The water temperature of described temperature detecting module detection of engine water tank, described CPU puocessing module is handled the temperature signal that described temperature detecting module is sent here, if the phenomenon of high water temperature, then the CPU puocessing module sends the control signal of tripping operation for the tripping operation Executive Module, changes the current load of motor by the tripping operation Executive Module; Simultaneously; the CPU puocessing module is returned and is shut down time delay module transmission shutdown time delayed signal; the shutdown time delay module picks up counting; and then moment of stopping operating of definite motor; when this arrives constantly; shut down time delay module and send stopping signal to shutting down Executive Module immediately, carry out the operation of shutting down, motor is stopped operating by shutting down Executive Module.
Wherein, described temperature detecting module comprises temperature transducer, input circlult and the A/D converter that is connected successively, among the present invention, temperature transducer adopts thermistor to realize, described input circlult is converted into voltage signal to the resistance signal of thermistor, by A/D converter this voltage signal is converted to digital signal, and gives described CPU puocessing module.
In addition, described temperature detecting module can be a water temperature alarm switch (as the method temperature detect switch (TDS)), and when being high water temperature, the water temperature alarm switch is connected, and when for low water temperature, the water temperature alarm switch disconnects.In this case, the CPU puocessing module can determine whether to be high water temperature according to the input state of water temperature alarm switch amount.
As shown in Figure 2, be the controlling method flow chart of the present invention to motor, the detailed process of this controlling method is as follows:
At first, the water temperature in the temperature detecting module detection of engine water tank, and temperature signal exported to the CPU puocessing module;
Secondly, the CPU puocessing module is handled this temperature signal, this temperature signal value and the temperature value of presetting is compared, if this temperature signal value is less than default temperature value, then the CPU puocessing module is judged as low water temperature, and the CPU puocessing module is not exported any control signal;
If this temperature signal value is greater than default temperature value, then the CPU puocessing module is judged as high water temperature, output alarm signal, and the control signal of output tripping operation is simultaneously given the tripping operation Executive Module; The tripping operation Executive Module is according to the tripping operation control signal that receives, the load of corresponding change motor;
Simultaneously, the CPU puocessing module is returned and is shut down time delay module output shutdown time delayed signal, shuts down time delay module and picks up counting, and determines the moment that motor stops operating, and the time of general time-delay was best between 1 to 2 minute; When the moment that motor stops operating arrives; then shut down time delay module and give shutdown Executive Module output stopping signal; by the rotation of shutting down the Executive Module shutting engine down; this has just finished when high water temperature appears in motor; get rid of engine load earlier; the process that back cooling time-delay is shut down helps reducing motor inside and outside cooling contraction ratio like this, avoids embracing the appearance of cylinder accident.
In the present invention, default temperature value scope is 95～105 degree, and promptly Yu She temperature value is 95～105 any one value, comprises the numerical value at two ends.When the water temperature of motor exceeds this default temperature value scope, think that then high water temperature phenomenon has appearred in motor; When tripping Executive Module when changing the load of motor, can some or all ofly get rid of engine load, even motor is in underloading or unloaded state operation down, this will depend on the application of motor, can suitably regulate.
Engine controller of the present invention can be applied on the engine power generation unit, because the time that generator set need move is long, occurs high water temperature phenomenon easily.
