Multifunctional 4G antenna capable of rapidly switching based on diagnosis connection state

Abstract

The invention discloses a multifunctional 4G antenna capable of rapidly switching based on a diagnosis connection state. The multifunctional 4G antenna comprises an antenna chassis. A main antenna isarranged on one side of the antenna chassis; an auxiliary antenna is arranged on the other side of the antenna chassis; each of the main antenna and the auxiliary antenna comprises an upper signal processing section and a lower T-BOX connection section; a first diagnosis resistor is connected between the upper signal processing section and the lower T-BOX connecting section of the main antenna, and a second diagnosis resistor is connected between the upper signal processing section and the lower T-BOX connecting section of the auxiliary antenna; and a cable connecting point is arranged on theT-BOX connecting section and connection with the T-BOX signal processor is realized through a cable. According to the scheme, through setting of the auxiliary antenna, the main and auxiliary antennascarry out switching operation, so that network interruption and communication connection interruption caused by poor signals can be prevented, and the problems that in the prior art, most vehicle-mounted 4G antennas are single antennas, main and auxiliary antennas do not exist, and communication interruption is likely to be caused in the driving process are solved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a fast switching multifunctional 4G antenna based on a diagnosis connection state. Background technique [0002] The vehicle-mounted T-BOX is mainly used to communicate with the background system / mobile APP to realize the vehicle information display and control of the mobile APP. When the user sends a control command through the mobile APP, the TSP background will send a monitoring request command to the vehicle T-box. After the control command is obtained, the control message is sent through the CAN bus to realize the control of the vehicle, and finally the operation result is fed back to the user's mobile APP. Only this function can help the user remotely start the vehicle, turn on the air conditioner, and adjust the seat to a suitable position. location etc. In vehicle communication products, T-BOX can be used to automatically detect whether the 4G antenna i...
