Simulation of generator output voltage control based on 51 single chip microcomputer

this paper introduces the design scheme of the latch control of the generator output electric wearer based on 51 single chip microcomputer. The throttle opening of the diesel engine is adjusted by controlling the steering of the stepping motor through the single chip microcomputer, so as to realize the latch control of the generator output electric wearer, and greatly improve the stability of the generator output electric wearer. The feasibility of this design scheme is verified by the simulation of Proteus Software

as shown in Figure 1, at the beginning, the switch sb is powered on, SA, SC and SD are disconnected, and the magnetic poles of phase B are aligned with the No. 0 and No. 3 rotating teeth. At the same time, the No. 1 and No. 4 rotating teeth and the magnetic poles of phase C and D windings are staggered, and the No. 2 and No. 5 rotating teeth are staggered with the magnetic poles of phase D and a windings. When the switch SC is powered on and Sb, SA and SD are disconnected, due to the action of the magnetic line of force of the c-phase winding and the magnetic line of force between the L and 4 teeth, it rotates, and the L and 4 teeth are aligned with the magnetic poles of the c-phase winding. However, No.0 and No.3 teeth are staggered with phase A and phase B windings, and No.2 and No.5 teeth are staggered with phase A and phase D winding poles. By analogy, if the four phase windings of, B, C and d supply power in turn, they will rotate in the directions of a, B, C and D. The composition of each mechanism of the system is shown in Figure 2. The system can be divided into detection link, control link and actuator. The detection link mainly includes the detection of output voltage, oil temperature, oil pressure and oil quantity. The control mechanism is composed of a single chip microcomputer, and the actuator is a Changzhou zhailai electric appliance company. The maximum static torque is about 36.6 million tons in China; 57BYGH stepping motor with a white paperboard output of 14.05 million tons and a rotational inertia of 80ncm of 2809 CMZ

2 working principle of the system

in this scheme, when the generator works normally and the output voltage is within the allowable range, the stepping motor will not act. When the oil temperature, oil volume and other abnormal conditions occur during the working process, the system will send an audible and visual alarm, and some manufacturers can only output the maximum force value. In this scheme, the error range of the output voltage and the expected output voltage are set according to the actual requirements, so that the upper and lower limits of the voltage in the adjustment process can be obtained. After the system is powered on, first judge whether the output voltage is greater than the upper limit value. If it is greater than the upper limit value, the program jumps to the inversion program to make the single chip microcomputer send out the inversion pulse, and the stepping motor after receiving the inversion pulse will reverse, so as to turn down the oil RJ of the diesel engine. At this time, the speed of the generator slows down, and the output voltage also decreases. Until the output voltage of the generator drops to the allowable range, the stepping motor stops positive action. Similarly, when the output voltage of the generator is less than the lower limit voltage value, the single chip microcomputer will send a positive rotation pulse signal to the stepping motor to make the stepping motor rotate forward, so as to increase the throttle of the diesel generator, increase the speed of the diesel engine, increase the output voltage, and finally adjust the output voltage of the generator to the set range. The whole system then judges whether the sensor signal of the tensile testing machine is normal, and the process is shown in Figure 2
