With universal wireless sensor works, expansion of the scope of monitoring and monitoring functions for incar system, car data acquisition and condition monitoring of equipment status and the necessary equipment control, topology control, topology query functions. Keywords: wireless sensor works。 monitoring system Introduction In order to satisfy the people to car safety, handling and fort requirements, vehicle integrated with more and more electronic system .At present, car electronic equipment is widely used 16 or 32bit microprocessor control. Creating invehicle monitoring system based on IEEE and ZigBee standard for wireless sensor works, designed to achieve a more optimized wireless sensor works, the progressive realization of the work of automotive systems, intelligent and controllable to provide highCar System security. System design In this paper, the existing vehicle system, the data transmission mode is extended to the wireless transmission mode, the realization of a star work data acquisition system. And can place each data acquisition node of the acquired data is transmitted to the gateway, the gateway through the serial port to upload data to the host puter, in the host data realtime waveform display, and method of database to preserve, for the followup data processing. The application of system object is posed of a temperature sensor, pressure sensor, speed sensor, speed sensor, a current sensor, pressure sensor, sensor subsystem. The purpose of this design is to use a monitoring host machine end to the detection of multiple target environment, taking into account the access data throughput and software system plexity, using timedivision multiplexing way, one by one on the terminal collecting point of control and data acquisition. As shown in Figure 1, the system is divided into 3 parts: Vehicle Monitoring Center, gateway and mobile sensor node. Gateway is the whole vehicle system core, and all vehicular sensor node munication. Vehicle monitoring center to the gateway sends a control mand by the gateway, the control mand is converted to an RF signal and sent to the vehicle sensor node. When the vehicle sensor nodes to transmit data, gateway into the data reception state, and upload data to the monitoring center for further processing. In addition, car between sensor nodes cannot municate with each other. The monitoring center of the monitoring software and gateway in RS232standard interface for munication. Vehicle sensor node life cycle is active and dormant periods. Nodes in the active phase of the pletion of data acquisition, data sent to the gateway, receiving and executing gateway mand。 in the dormant period off the wireless RF module in order to save energy, until the next active period. System through this mechanism of dormancy to reduce energy consumption, extend the time span of the system as a whole. The system used PC as the control center, PC machine monitoring software in VB development environment, is a dialog based application software. In order to improve the munication module of the intelligent level, in the design, its function is not limited to the realtime data display, all of the data collection by the monitoring software by sending a request signal to the trigger. Considering the original data for subsequent processing and indepth analysis of the vehicle system, can accurately judge, software has also added data preservation of the document and data file display function. Generally speaking, the whole work are controlled by the host monitoring software, the working process of every node of the work is the need of human participation. 2 hardware system design chip introduction
