Vehicle Fuel Consume Monitoring System Design

Nowadays, logistics and freights have already developed, and bring plenty of energy to market economy. But a lot of instances about issuing more invoices and getting oil privately happen now and again, becoming a trouble thing for company vehicles management. And for the companies in this field, it's a no small spending. For this fact problem, there is the vehicle fuel consume monitoring system, designed for recording oil capacity and querying the oil variety in the PC software, to confirm whether every vehicles uses oil normally.The ZigBee technology based on the sensor network is portable moving devices with a kind of low cost, low complex, low data rate and short distance. At present, it has been applied in a wide field such as the electrical appliances controlling, the defense of forest fire, the wireless meters and so on. Based on the understanding of protocol, regarding plenty of vehicles as wireless sensor nodes, and regarding stations as wireless sensor network, using ZigBee technology resolves the communications between moving nodes and plat stations, and solves the data collection and transmission.This system is applied to monitoring fuel consume of vehicles. Contents abort this lecture is the hardware and software design of Router and Coordinator, and programme of monitoring management software. The system uses JN5121-M02 high power module for wireless transfers, realizing establishment of network topology. Data transfers works at public frequency of 2.4GHz.The chip integrates all RF components and wireless microprocessor, so as to shorten exploitation cycle.There are a lot of practical tests to validate the stability and data transmission status, and the result is basically satisfied comparing with anticipation. This system is a prior experimental edition of a series, including many shortages in it, so wishing the people who has a common objective to raise your criticism and advices, for a better management of this field.
