Background technology
Electric bicycle is to be that the energy is the vehicles of power with the direct current generator with the battery.The DC motor controller theory diagram that existing electric bicycle is made up of microprocessor as shown in Figure 1, the brake signal of electric bicycle, rate signal, locking signal, restricting signal enter the switching value I/O port of 8-bit microprocessor for the switching value input signal, and moment sensing signal, battery voltage signal, current sampling signal that speed-regulating signal, people are pedaled power are the A/D conversion port that analog input signal enters microprocessor.Wherein less because of the current sampling signal of motor; can produce very mistake when directly carrying out the A/D conversion by 8-bit microprocessor; cause the current protection value inaccurate, so just can enter microprocessor after the current protection precision needs the peripheral hardware amplifying circuit to handle and carry out the A/D conversion in order to improve.Microprocessor requires to carry out speed governing to output pulse width modulation signal after these signal Processing and through the driving circuit pushing motor according to program, finishes simultaneously to show functions such as output, 1: 1 power-assisted, speed locking, under-voltage and current protection as electric weight and state.The electric bicycle DC motor controller feature richness that adopts microprocessor to form is so be widely used.
But the 8-bit microprocessor that above electric bicycle DC motor controller is adopted all can not carry out processing and amplifying to the current sampling signal of motor, the current sampling signal of motor enters before the A/D conversion port of 8-bit microprocessor chip, all to form amplification treatment circuit by components and parts independently, so sort controller circuit complexity is easy to generate fault, and the cost height.
The utility model content
In order to solve the above-mentioned shortcoming that the existing electric bicycle DC motor controller of being made up of 8-bit microprocessor exists, the utility model provides a kind of programmable amplifier that utilizes 8-bit microprocessor inside the current sampling signal of motor to be carried out the electric bicycle DC motor controller of processing and amplifying, the current sampling signal of motor just need not be established treatment circuit again and directly use the amplification treatment circuit of 8-bit microprocessor inside like this, to reach the simplification circuit, reduce cost, improve stability, reduce the purpose of volume.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of electric bicycle DC motor controller of forming by microprocessor, form by power circuit, battery voltage detection circuit, driving circuit, motor promotion field effect transistor T1, display output circuit, signal input circuit, microprocessor IC1, the microprocessor circuit chip that programmable analog circuit is arranged in IC1 has adopted is configured to amplifier by programming with mimic channel.The processing and amplifying of the current of electric sampled signal of electric bicycle has been used the amplifier of microprocessor circuit chip IC1 inside.As seen from Figure 2, form a programmable system on chip in the dotted line, the integrated required signal processing function of existing electric bicycle DC motor controller current of electric sampled signal.
The effect that the utility model is useful is that circuit is simple, cost is low, volume is little, stable performance, and the electric parameter of amplifier can be set by program, has improved the speed of work efficiency and product renewal, and the intelligent degree of properties of product improves.
