PLC control system hardware is mainly composed of PLC module, intermediate relay, contactor, digital table and a number of buttons. Figure 3 is an example of PLC control of finished material elevator of asphalt mixing equipment. The action of the system is as follows: The starting position of the lifting bucket is at the bottom loading position A, when the PLC detects that the agitator is in the open state, the lifting bucket will start lifting after 10s delay, and then be lifted to the high-end discharge level B. After 10s delay discharge, the hoisting bucket will be replaced with electricity, and the hoisting bucket will be lowered, and when it is lowered to the bottom close to the switch C, the hoisting bucket will be powered off after 1s delay, and the hoisting bucket will slide to the bottom loading position A for standby. When the blender is detected to be on, the next cycle begins again.

3, the computer control system hardware is mainly composed of industrial control computer system, management computer, printer, power UPS, intermediate relay, contactor, digital table and a number of buttons. Industrial control computer system is mainly composed of CPU, data acquisition and amplification part, A/D analog-to-digital conversion, analog amplification, communication, I/O input and output switching and bus parts. Figure 4 shows the computer control system of asphalt mixing equipment. The main target of control is the control accuracy of asphalt, stone, powder and temperature measurement. The input and output signals of control mainly come from the mixing building, finished material elevator, main burner and drum, etc. The frontier control core is the industrial computer.
The working process of the control system: first open the drying drum, hot lift, vibrating screen, induced draft fan, blower, and then ignition and oil pump at the same time, and preheat the drum with a low fire for 3 ~ 5min, and then the cold material grader starts feeding, slowly increase the throttle to heat up, when the material temperature rises to the set temperature, start automatic temperature control, so that the temperature is controlled within the set value of ±5℃; Observe the material level of the hot bin, when the hot material reaches a certain level, start the automatic key to start mixing, all kinds of material feeding, weighing, unloading and mixing are automatically carried out, management computer can set and display the weight and ratio of various materials, particle temperature, control the production process and fault alarm, and cooperate with the printer to print the production process parameters at any time
