Embodiment Construction

[0016] Such as Figure 1-2 As shown, a remote vehicle monitoring terminal data information transmission method described in the embodiment of the present invention is characterized in that it includes the following steps:

[0017] 1), the remote vehicle monitoring terminal is installed on the vehicle, and communicates with the vehicle through the CAN bus, and the remote vehicle monitoring terminal includes a power supply module, a GPRS communication module, a CFD card storage module, a microcontroller module, and a data processing module And the CAN communication module; the remote vehicle monitoring terminal collects the information to be monitored from the whole vehicle, and groups, packs and encrypts the data;

[0018] 2) During the driving process of the vehicle, the remote vehicle monitoring terminal monitors in real time whether the area entered has a GPRS signal: the area entered has a GPRS signal, and the remote vehicle monitoring terminal sends the grouped, packaged, ...

Abstract

The invention relates to a method for transmitting data information of a remote vehicle monitoring terminal. The method includes the following steps: (1) the information required to be monitored is collected by the remote vehicle monitoring terminal, and data are grouped, packaged and encrypted; (2) in the vehicle driven process, the remote vehicle monitoring terminal monitors whether a GPRS signal exists in an entering area or not in real time, corresponding processing modes are selected according to the existence condition of the GPRS signal, and finally the data are transmitted to a monitoring platform through the remote vehicle monitoring terminal; (3) the data are received by the monitoring platform in real time, and the data are saved in a database and displayed on a display screen of the monitoring platform. The method has the advantages that when a new energy electric vehicle is driven to a place with the weak GPRS signal or free of the GPRS signal, collected information on the whole vehicle cannot be transmitted to the monitoring platform in real time, and the collected data are stored in a CFD card storage module through the remote vehicle monitoring terminal; when the new energy electric vehicle is driven to a place with the normal GPRS signal, the data in a CFD card are transmitted to the monitoring platform, the data obtained by the monitoring platform are completed, and the driving route is not disconnected.

Description

technical field [0001] The invention relates to a data information transmission method of a remote vehicle monitoring terminal. Background technique [0002] At present, the data transmission of the remote vehicle monitoring terminal applied on the electric vehicle adopts the GPRS wireless public network mode for transmission. Although the GPRS signal has a high coverage rate, there are still certain areas without signal, such as underground garages and underground tunnels. New energy vehicles need real-time and continuous monitoring of the core components, especially the various states of the power battery and the various states of the motor. If there is data interruption, it will have a great impact on the operation analysis of the vehicle and parts. For this reason, a method of finally sending the data back to the monitoring platform in a certain way is proposed in the GPRS no-signal area. Contents of the invention [0003] The purpose of the present invention is to p...
