The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
With reference to shown in Figure 1, electric four-wheeled truck control device of the present utility model, comprise the first motor, also comprise control circuit, the first driving circuit, control circuit comprises controller, the first filtering and amplification treatment circuit, a PWM amplifying circuit, the mouth of controller connects a PWM amplifying circuit, and the input end of controller connects the first filtering and amplification treatment circuit; The one PWM amplifying circuit connects the first driving circuit, and the first driving circuit connects the first motor, and the first filtering and amplification treatment circuit connect respectively the first motor and the first driving circuit.The present invention does not limit the range of use of electric four-wheeled truck control device, and it can be applied in substation inspection, also can be applied in the occasion that any other the present invention relates to.
During real-world operation, the first motor is by its position signal, the first driving circuit by its current signal transfer to controller, for the controller analysis, controller is according to the first motor position signal and the first driving circuit current signal that obtain, controlled amount, and export to a PWM amplifying circuit, the one PWM amplifying circuit is exported to the first driving circuit after signal is amplified to modulation, and the first driving circuit drives the first motor rotation.
In reality, the position signal of the first motor, the current signal of the first driving circuit are all with very large interference, and they will pass through the links such as amplification, shaping, filtering, and controller just can obtain accurately pure signal like this.Therefore in the utility model, the first filtering and amplification treatment circuit connect respectively the first motor and the first driving circuit, the first filtering and amplification treatment circuit are responsible for the position signal to the first motor, the processing such as the current signal of the first driving circuit amplifies, shaping, filtering, and treated signal is transferred to controller.The utility model does not limit the position signal of the first motor, the current signal of the first driving circuit obtains and is transferred to the first filtering and amplification treatment circuit by which kind of mode, in reality, the first motor can be provided with position transduser, the first driving circuit can be equipped with current sensor, this position transduser is connected respectively the first filtering and amplification treatment circuit again with current sensor, by the position signal of the first motor, the current signal transfer of the first driving circuit is given the first filtering and amplification treatment circuit.
In the utility model, adopted a PWM amplifying circuit, the signal strength of exporting to a PWM amplifying circuit due to controller is less, generally only has the 3.3V left and right, and out of reach drives the requirement of the first driving circuit, therefore must, through amplifying, could effectively drive the first driving circuit.
For the safe and reliable work of support system better, control circuit of the present utility model also comprises the first protective circuit, and the input end of the first protective circuit connects respectively the first driving circuit and the first motor, and the mouth of the first protective circuit connects controller.The utility model does not limit concrete safety method and the inner structure of the first protective circuit, such as the first protective circuit can be divided overcurrent protection, overvoltage protection, under-voltage protection and temperature protection etc.The first protective circuit can detect voltage, the temperature of the first driving circuit, detects the electric current of the first motor, then according to these detection limits, protects accordingly.
