Because the function of DTU is relatively simple, that is, data transparent transmission, the functions of users are ever-changing, and the application scenarios of different industries are also different.
[0003] The function of DTU is relatively simple, that is, data transparent transmission. The functions of users are ever-changing, and the application scenarios of different industries are also different. For example, in the breeding industry, the application environment is relatively harsh, and it will affect factors such as water ingress, dust ingress, and signal instability. , the existing DTU gateway has poor stability and reliability and cannot adapt to today's breeding environment

The invention relates to the technical field of farm wireless data transmission, in particular to a livestock farm DTU gateway system which comprises a control system and a gateway sealing shell, the gateway sealing shell comprises an upper shell body, a lower shell body, connecting screws, a circuit board, a 485 converter and an interface, the circuit board is arranged in the lower shell body, the circuit board checks signals through a main control chip and a communication module. The built-in 485 converter can adapt to 485 signals, so that the application range is wider; the upper shell body and the lower shell body are respectively provided with a first connecting edge and a second connecting edge, a sealing plug is arranged on the lower surface of the first connecting edge, a matched sealing groove is formed in the second connecting edge, when the sealing plug is plugged into the sealing groove, the sealing performance of the upper shell body and the lower shell body can be improved, and then the waterproof performance and the dustproof performance of the sealing shell are improved. The gateway can be applied to various severe environments, and the service life of the gateway is prolonged; a plurality of interfaces with built-in sealing rings are mounted for connecting equipment, so that water and dust can be prevented from entering, the safety is higher, and the system is more worthy of popularization and use.
Description
technical field [0001] The invention relates to the technical field of wireless data transmission for farms, in particular to a DTU gateway system for farms. Background technique [0002] In the current field of wireless data transmission technology for farms, the DTU gateway is one of the essential devices. DTU is the abbreviation of Data Transfer unit. It is transparently transmitted to the server, and is specially used for wireless terminal equipment that converts serial port data into IP data or converts IP data into serial port data and transmits it through the 4G communication network. Because the function of DTU is relatively simple, that is, transparent transmission of data, the functions of users are ever-changing, and the application scenarios of different industries are also different. [0003] The function of DTU is relatively simple, that is, data transparent transmission. The functions of users are ever-changing, and the application scenarios of different indu...
