传统的运料小车大都是继电器控制，而继电器控制有着接线繁多，故障率高的缺

Most of the traditional material transport vehicles are controlled by relays, and the relay control has the disadvantages of numerous wiring, high failure rate, and difficult maintenance and repair. As the mainstream controller in the current domestic control market, PLC plays an important role in market, technology, industry influence, etc. It is a general trend to use PLC control instead of relay control. <br> The working environment of the feeding and loading control system is usually relatively harsh, so the safety, reliability, and ease of maintenance of the feeding and loading control system are required to be high. The S1200 PLC software with high reliability is used to control the system to realize the automatic control process of the feeding and loading system, which can meet the requirements of system reliability, stability and real-time. <br> This design is to realize the manual and automated conversion of the feeding trolley, change the simple manual feeding of the previous trolley, reduce labor, improve production efficiency, and realize automated production! Moreover, the design of the feeding trolley is conceived because the working environment is bad and people are not allowed to enter the working environment.

Most of the traditional transportation trolleys are relay control, and relay control has a wide range of wiring, high failure rate shortcomings, and maintenance and maintenance is not easy to do so. As the mainstream controller in the current domestic control market, PLC plays an important role in the market, technology, industry influence and so on, and the use of PLC control instead of relay control has become the trend.<br> The working environment of the feeding loading control system is usually harsh, so the safety, reliability and maintenance simplicity of the feeding vehicle control system are high. The system is controlled by the high-reliability S1200 PLC software, and the automatic control process of the feeding loading system can be realized to meet the requirements of system reliability, stability and real-time.<br> This design is to achieve the manual and automated conversion of the delivery trolley, change the simple manual feeding of the previous trolley, reduce the labor force, improve production efficiency, realize the automatic production! And the design of this delivery trolley is due to the poor working environment, do not allow people to enter the working environment of the case bred.

Most of the traditional trolleys are controlled by relays, which have many disadvantages, such as various wiring, high failure rate, and difficult maintenance. As the mainstream controller in the domestic control market, PLC plays an important role in the market, technology, industry influence and so on. It is the general trend to use PLC control to replace relay control.<br>The working environment of the feeding and loading control system is generally poor, so the requirements for the safety, reliability and maintenance simplicity of the feeding and loading control system are high. S1200 PLC software with high reliability is used to control the system and realize the automatic control process of feeding and loading system, which can meet the requirements of system reliability, stability and real-time.<br>The purpose of this design is to realize the transformation of manual and automatic feeding car, change the simple manual feeding car in the past, reduce labor force, improve production efficiency, and realize automatic production! Moreover, the design of the feeding car is formed under the condition that the working environment is bad and people are not allowed to enter the working environment.
