[0002] Modern port logistics is becoming increasingly complex. A large number of goods need to be transported efficiently and stably and processed quickly. The application of port gantry cranes, quay container cranes, stackers, and container front loaders has become an indispensable equipment for modern port logistics.

[0003] At present, various equipment adopted by each port is also becoming more and more intelligent and efficient, and can remotely and real-time understand each equipment and the equipment safety data during operation, improving the operation efficiency and safety of the port and promoting the development of modern port logistics.

[0004] During the use of equipment, the tires of the equipment are one of the important safety monitoring items. Tire safety data includes the current tire pressure and tire temperature, etc. Real-time monitoring of its data can effectively prevent the equipment from having a flat tire during operation, resulting in safety accident problems.

[0005] The current real-time monitoring method, such as a gantry crane, is to connect a tire pressure sensor to the tire of the gantry crane. The tire pressure sensor sends the tire safety data to the tire pressure monitoring information receiver in real time through wireless communication. The tire pressure monitoring information receiver sends the tire safety data to the cloud and the display screen in the cockpit respectively, facilitating the driver and remote safety personnel to obtain the current tire safety data information in real time and perform corresponding tire maintenance work.

[0006] As one of the important hardware in the whole monitoring system, the tire pressure sensor needs to ensure a certain service life. The tire pressure sensor is internally provided with a small battery and adopts a detachable structure design. Although the detachable mechanism design can realize the replacement of the battery, due to the low power consumption of the tire pressure sensor, the battery does not need to be replaced frequently. And with the detachable structure design, port equipment all works outdoors. In the port environment with high temperature, high humidity and high salt, due to the lack of a sealing structure for the tire pressure sensor, moisture is easy to enter the product, corrode the internal circuit board, affect the service life of the product, and cannot meet the usage requirements of the staff, which is not conducive to improving the competitiveness of the product.
