Internet of Vehicles data collection and transmission and emergency rescue terminal based on Tiantong No.1 satellites

Abstract

The invention discloses an Internet of Vehicles data collection and transmission and emergency rescue terminal based on Tiantong No.1 satellites, and aims to provide a data collection card integratinga satellite channel mode and a ground base station mode. A packet data exchange service of a satellite communication system is utilized to provide a data transmission service with the bandwidth of 9.6 Kbps, a series of problems that a ground base station is poor in signal and cannot transmit data are solved, the Beidou satellite positioning function and the Tiantong satellite one-key rescue function are both achieved, and the vehicle-mounted functionality and the user safety are greatly improved. The design of the system is shown in figure 1. The system comprises the following parts: (1) an RS485 and CAN data collection module, (2) a CPU processor, (3) a Tiantong satellite communication module, (4) a GPRS module, (5) an Ethernet0 network connection module, (6) an Ethernet1 data collectionmodule, (7) a satellite one-key rescue function, and (8) a satellite positioning function. The core of the design is that data collection and transmission are realized by using double channels of a satellite and a ground base station, Meanwhile, the functions of positioning and one-key rescue are realized.

Description

technical field [0001] The patent of the present invention can provide a terminal that automatically selects the satellite channel or ground base station channel for data collection and transmission according to the signal strength. It has both satellite positioning and satellite one-key rescue functions, and can monitor and configure the terminal at the same time. Background technique [0002] Generally, data is transmitted through ground base station channels. With the development of science and technology, a single base station channel can no longer meet the needs of the market. From the perspective of function and safety, based on the satellite channel, we have added the Beidou satellite positioning system and Tiantong satellite one-key rescue function, forming a dual-channel vehicle-mounted mobile terminal compatible with satellite channels and ground base station channels.
