Abstract

The invention discloses a remote real-time monitoring method of a big-bus operating status, fuel consumption and exhaust gas emission. The remote real-time monitoring method comprises the following steps: an online communication model is established between a server and a wireless communication module; user request information forms control instructions by the server, and the control instructions are transmitted to the wireless communication module through a router, an internet and a wireless network after being encrypted, and the encrypted control instructions are transmitted to a bus information acquisition unit through the wireless communication module; the encrypted control instructions are decrypted by the bus information acquisition unit, the big-bus operating status, and the fuel consumption and exhaust gas emission data are acquired from the CAN (Controller Area Network) bus of the big bus and processed, and the real-time data is encrypted and transmitted to the wireless communication module; the encrypted real-time data is transmitted to the server through the wireless communication module and decrypted through the server, the decrypted data is processed and accessed by the client of the user. The monitoring system comprises the server, the router, the wireless communication module installed on the big bus, the big-bus information acquisition unit and the power supply module.

Description

technical field [0001] The invention belongs to the technical field of remote real-time monitoring of automobiles, and in particular relates to a remote real-time monitoring method and monitoring system for the running state, fuel consumption and exhaust emission of buses. Background technique [0002] Buses are a widely used means of public transport for people. Their operating conditions (vehicle speed, stroke, engine speed, temperature and pressure of gearbox lubricating oil, etc.), fuel consumption and exhaust emissions directly affect the safe operation and economy of buses. Therefore, real-time monitoring of bus operation status, fuel consumption and exhaust emissions is an important part of bus management and is very necessary. [0003] CN201220475334.0 discloses a remote monitoring system for passenger car energy consumption, which includes a passenger car energy consumption data acquisition device, a GPRS module, and a data processing and display device. Among them...
