Ac inction motor is widely used in all kinds of instry, agriculture, military and household appliances instries, but so far, besides, the high level of the universal programmable controller, has not appeared yet a special applies ac asynchronous motor, low price programmable controller procts. Therefore, based on the current situation, the research development with a singlechip can adapt to any ac inction motor drives sequential control device.
In order to meet different requirements driven by Atmel company system as main control chip, expand 89C51, through other functions by SSR circuit of single-phase capacitor startup method to control the drive motors. Due to demand and often cycle changes, so the system application EEPROM memory technology, using the time constant memory I2C bus priority 4KB way of electromechanical road extended EEPROM, which promoted the speed of communication, and save the microcontroller I/O resources. With a keyboard and display human-machine conversation interface. Using solid-state relay as the main circuit switching devices, according to the work, the power supply system design for two ways of output: all the power system as MCU + 5V, Another way to the 12V supply as the relay output. In order to prevent the positive &negative switching short-circuited when added by two diodes, composed of interlock protection circuit. System with short circuit, overload protection, etc.
Widely used in control of controller by ac inction motor drive and control sequence precision of proction equipment. To complete control function, high reliability and flexibility, and setting device is easy to operate, small volume, low power consumption, low price of superiority.
Topic: 89C51 design principle, a dedicated PLC to control the timing of single-phase motor work. In the design of the control method, the main research design, hardware circuit and software programming and debugging. This proct cost, high control accuracy, and can meet the majority of small and medium-sized enterprises and large enterprises in the sequence of single-phase motor control requirements.
Keywords: single motor controller hardware and software solid-state relay control sequence

The single phase AC asynchronous motor by the widespread application in each kind of instry, agricultural, the military and in domestic electric appliances' profession, may so far, besides the medium and high price general programmable controller, not yet appear one kind to be suitable specially for the single phase AC asynchronous motor's ultra low end programmable controller proct. Therefore, in view of this present situation, this topic research develops one to be possible to adapt the sequential control installment which take the monolithic integrated circuit as the core any single phase AC asynchronous motor actuates.
to satisfy the different actuation technological requirement, the system uses Atmel Corporation's 89C51 to take the master control chip, expands other function electric circuit, to uses the capacitor start law dragging through SSR the single-phase motor to carry on the control. Changes frequently as a result of the cycle along with the demand, therefore in the system takes the craft time-constant memory using EEPROM, selects the I2C main line method to expand 4KB for the main engine electric circuit EEPROM, both has promoted the communication speed, and has saved the monolithic integrated circuit I/O mouth resources. Has man-machine conversation connections and so on keyboard and demonstration. Uses the solid state relay to take main circuit's switch component, according to system's job requirement, the power source design to have two groups outputs: Group +5V takes the monolithic integrated circuit electrical power system; Another group outputs 12V to take the relay power source. In order to prevent when is reversing the cut creates the short circuit, additionally built the interlock protection circuit which is composed of two diodes. The system has protective measures and so on short circuit, overload, undervoltage.
the controller widely is suitable in controls each kind to drive and to request the sequential control precision high proction equipment by the single phase AC asynchronous motor. Achieves the complete control function, high reliable and the nimble time setting way, and enables the equipment to have the simplicity of operator to be convenient, the volume is small, the power loss is low, price low status prominent superiority.
topic objective: Designs special-purpose PLC with the 89C51 monolithic integrated circuit, controls single-phase motor's work succession. In the design, mainly studies its control method, designs the hardware circuit as well as the software programming, the debugging. This proct cost is inexpensive, the control precision is high, may satisfy in the overwhelming majority small and medium-sized enterprise even Major instry to single-phase motor's sequential control request.
