　　Container spreader is operating in very bad conditions, and its probability of failure accounts for more than 30% of the total system failure. In order to make the fault judgment more quickly and accurately, the following editor introduces a new type of signal analysis and fault judgment method for container spreader .

　　Spreading signals are usually transmitted through the spreader cable. In the new control technology, unlimited industrial Ethernet network communication is adopted to realize signal transmission, and point-to-point contact method is adopted. There is no need for a server in the middle. You can get judgments and displays such as unlocking failures, locking failures, implantation signals at each corner. The display can be seen on the driver's room catalyst screen, and specific instructions are also arranged on the spreader, so that maintenance personnel can be convenient.

　　The use of wireless communication to control the spreader and realize the judgment of specific faults of the spreader shows that it is a new attempt. The actual test results are good. The original wireless communication problem did not appear. Under the harsh working conditions of the spreader, the PLC and communication module on the spreader work normally. Because the communication speed reaches 10MHz and the data volume is limited, the control is real-time, which increases the system stability and reliability, making it more convenient for outdoor gantry cranes and other lifting equipment to be used on site.
