Problems solved by technology

[0005] However, there are at least the following problems in the way of passively adjusting the transmission power in the prior art: the environment where the vehicle detector is located is not static, and it will also change (such as increasing or decreasing the surrounding interference sources). When the environment of the vehicle detector changes, communication with

Abstract

The invention provides an adaptive power adjusting method and apparatus, and relates to the technical field of vehicle detection. The method comprises the following steps: an upper end device broadcasts network access configuration information, wherein the network access configuration information is used for establishing a communication connection with a vehicle detector; the upper end device receives a communication signal sent by the vehicle detector after establishing the communication connection with the vehicle detector according to the network access configuration information, wherein the communication signal carries transmitting power and reporting state information of the vehicle detector; the upper end device determines communication quality with the vehicle detector according to the transmitting power and reporting state information carried in the communication signal; and the upper end device adjusts the transmitting power of the vehicle detector according to the determined communication quality. By adoption of the adaptive power adjusting method and apparatus, the overall power consumption of the vehicle detector is reduced while the wireless communication quality of the upper end device and the vehicle detector is guaranteed, the service life of the battery in the vehicle detector is prolonged, and the purpose of prolonging the service life of the vehicle detector is realized.

Description

technical field [0001] The present invention relates to the technical field of vehicle detection, in particular to a power self-adaptive adjustment method and device. Background technique [0002] The vehicle detector, with the motor vehicle as the detection target, detects the passage or existence of the vehicle, and its function is to provide sufficient information for the intelligent traffic control system to perform optimal control. [0003] The vehicle detector itself includes a battery, and the service life of the battery is a key factor affecting the life of the vehicle detector. Under the premise of a certain battery capacity, the vehicle detector usually solves the problem of service life by reducing its own operating power consumption. In order to ensure the communication quality between the vehicle detector and the upper-level equipment (that is, the remote receiver), the radio frequency part of the vehicle detector needs to drive the antenna with sufficient powe...
