Problems solved by technology

The existing sensor networking technology is based on the wireless signal strength. Usually, each sensor is connected to the adjacent sensor. However, there may be no direct road connection between the two adjacent signal lights. That is, the two are unreachable, so even if the two signal lights are networked, there is no doubt
Therefore, the existing sensor networking technology is not suitable for traffic control systems. How to control the sensors in the traffic control system for networking has become one of the technical problems to be solved urgently in the prior art.

Embodiment 2

[0064] During specific implementation, since the road connection information stored on the network side may be updated, for example, according to the needs of traffic control, a certain intersection is not allowed to pass through in a certain period of time, so this information is updated to the above road connection information, the The road connection information between the intersection and other intersections changes, and in this case, the signal lights on the intersection are not allowed to network with other signal lights.

[0065] Based on this, in the embodiment of the present invention, after the first signal light and the second signal light complete networking, the following steps may also be included:

[0066] Step 1. The first signal light acquires road connection information according to a preset cycle;

[0067] Step 2. Determine whether the road connection information is updated, if yes, perform step 3, otherwise, perform step 5;

[0068] Step 3. The first sign...

Abstract

The invention discloses a sensor networking control method and device, and is used for networking of sensors in a traffic control system. The method and device can be applied to an intelligent traffic control system, the intelligent traffic control system comprises at least two signal lamps, and each signal lamp is equipped with a sensor. The method includes: a first sensor on the first signal lamp receives a networking request sent by a second sensor on a second signal lamp, wherein the networking request carries road information and lane information of an intersection where the second signal lamp is located which are collected by the second signal; the first signal lamp acquires road connection information; the first signal lamp judges whether preset networking conditions are satisfied according to the acquired road connection information and the received road information and lane information; if yes, the networking request is accepted; and if no, the networking request is refused.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a sensor networking control method and device Background technique [0002] With the development of urbanization, the traffic congestion schedule is known as one of the hot issues in the urbanization process. How to solve traffic congestion has become a major problem in the process of urbanization. [0003] Currently, there are mainly the following solutions for traffic congestion: [0004] 1. Using traffic lights for control [0005] By referring to the road traffic congestion situation, the traffic lights are set according to the experience value, and the idle time and busy time are operated according to the fixed time and program. In recent years, intelligent traffic light control technology has emerged, which is based on preset strategies or empirical data to control the switch parameters of traffic lights to achieve the purpose of traffic control. ...
