Embodiment 1

[0050] Such as figure 1 As shown, the present invention provides a certain traffic light control system, including: a geomagnetic detector module, a host computer, a traffic light module and a control host.

[0051] The control host is respectively connected to the geomagnetic detector module and the traffic light module. The geomagnetic detector module is arranged on the left-turn lane and the right-turn through lane at the entrance of the intersection.

[0052] The geomagnetic detector module is used to detect vehicle information at crossings, and the vehicle information includes whether there is car information and vehicle speed; the geomagnetic detector module includes a first geomagnetic detector and a second geomagnetic detector; the first The geomagnetic detector is set at the first detection point ● at the intersection entrance, the second geomagnetic detector is set at the second detection point ◆ at the intersection entrance, and the distance between the first detec...

Embodiment 2

[0056] Such as figure 2As shown, a traffic light control method provided by the present invention includes:

[0057] Step 201: Obtain vehicle information at the first detection point and vehicle information at the second detection point.

[0058] Step 202: Determine the traffic congestion at the detection point according to the vehicle information at the first detection point and the vehicle information at the second detection point. Step 202 specifically includes:

[0059] Judging whether the vehicle speed of the vehicle information at the first detection point is less than a first set threshold, to obtain a first judgment result. If the first determination result is yes, it is determined that the traffic congestion at the first detection point. If the first determination result is negative, it is determined that the traffic at the first detection point is normal.

[0060] Judging whether the vehicle speed of the vehicle information at the second detection point is less ...

Embodiment 3

[0072] The invention also provides a specific application mode of the traffic light control system.

[0073] The geomagnetic detector module, the control host and the traffic light module are networked through Zigbee communication technology to realize wireless communication. The geomagnetic detector module collects the traffic congestion at the intersection, and transmits the information to the control host through the built-in Zigbee module of the geomagnetic detector. The control host uses STC8A8K64S4A12 as the main control chip, and forms a wireless communication network with the geomagnetic detector and traffic light module through the Zigbee module , the Zigbee module model is ZM5161P2-2. Such as Figure 4 As shown, the STC8A8K64S4A12 communicates with the Zigbee module through the serial port. The control host judges the duration of the traffic lights at the intersection according to the received intersection congestion information, and then sends the control signal to...

Abstract

The invention discloses a traffic light control system, and relates to the field of traffic light control. The system comprises a geomagnetic detector module, a traffic light module and a control host. The control host is connected with the geomagnetic detector module and the traffic light module; the geomagnetic detector module is used for detecting vehicle information at an intersection; the geomagnetic detector module comprises a first geomagnetic detector and a second geomagnetic detector; the first geomagnetic detector is arranged at a first detection point of an entrance of the intersection, the second geomagnetic detector is arranged at a second detection point of the entrance of the intersection, and the distance between the first detection point and the intersection is smaller than the distance between the second detection point and the intersection; and the control host is used for judging the traffic jam condition of the intersection according to the vehicle information detected by the geomagnetic detector module and controlling the work of the traffic light module. According to the system and a method provided by the invention, the low-cost detection of the vehicle information is realized through the geomagnetic detector, and then the traffic lights are controlled through the vehicle information so as to relieve the traffic jam condition.

Description

technical field [0001] The invention relates to the field of traffic light control, in particular to a traffic light control system and method. Background technique [0002] In recent years, due to the increase in the number of motor vehicles, the phenomenon of traffic congestion continues to occur, and the importance of traffic light control is also increasing day by day. In the prior art, traffic lights are controlled through video images or infrared sensors to count traffic flow data, and the traffic control host adjusts the duration of traffic according to the size of traffic flow. The algorithm of traffic flow statistics through video images is relatively complex and requires high hardware requirements. The traffic flow data is counted by the infrared sensor, which is greatly affected by the weather. The traffic flow acquisition equipment used in these methods not only has high cost, but also requires a large amount of construction, and the installation cost is also v...
