Rechargeable miniature vehicle sensor based on ZigBee

Abstract

The invention provides a rechargeable miniature vehicle sensor based on ZigBee. The rechargeable miniature vehicle sensor comprises a detection module, a power module, a control module and a transmitting module which are in mutual coupling connection. The power module comprises a charging control module and a power protection circuit. The detection module comprises a detection coil and an oscillator formed by an inverter, and the detection coil is connected with the inverter. According to the rechargeable miniature vehicle sensor based on ZigBee, the wireless communication technology ZigBee is used in the design, thus a feeder line is omitted, the installation of a sensor is fast and convenient, the novel single chip microcomputer control technology is utilized, the sensitivity and reliability of the sensor are raised, the false detection rate is reduced, at the same time the sensor is intelligent, power consumption can be significantly reduced, and self examination and power consumption are realized. Secondly, novel power control and charging control chips are employed to form the power module, and the service life of the sensor is greatly prolonged, and the management of the sensor is simplified.

Description

technical field [0001] The invention relates to a ZigBee-based rechargeable miniature vehicle sensor. Background technique [0002] In today's economic development, urban traffic flow also increases, highways and urban traffic problems are universal problems in all countries in the world, which directly affect economic development and people's lives. The Intelligent Transportation System (ITS) is an effective way to solve the increasingly serious highway and urban traffic problems, and the vehicle detector is one of the most important traffic data collection devices in the ITS. The existing inductive coil type vehicle sensor still has some shortcomings, such as the volume of the inductive coil is too large (1 m × 2 m), the feeder needs to be installed, the amount of installation work is large, the traffic needs to be blocked during installation, and the inductive coil is easily damaged. Difficult to repair after damage, short service life and so on. SUMMARY OF THE INVENTI...
