Detailed Description

The embodiments of the present invention will be described below with reference to the drawings.

Referring to fig. 2, fig. 2 is a schematic diagram of an architecture of a traffic signal control system 20 according to an embodiment of the present invention, the traffic signal control system 20 includes a traffic signal controller 201, at least one cooperative apparatus 202, and at least one traffic light group 203, where:

when there are multiple turning-assistant devices 202, the multiple turning-assistant devices 202 can be deployed at different passing orientations of the same intersection, as fig. 3 illustrates four passing orientations of an intersection, namely a passing orientation 311, an orientation 312, a passing orientation 313 and a passing orientation 314, wherein the four orientations can deploy different turning-assistant devices 202 and traffic light sets 203 respectively. The turning-coordination device 202 deployed at any one passing direction of the intersection is used for controlling the traffic light group 203 deployed at the same passing direction. As shown in fig. 4, the corotation device 202-1 disposed in the passing direction 311 is used for controlling the traffic light group 203-1 disposed in the passing direction 311, and the corotation device 202-1 and the traffic light group 203-1 may be considered to be associated with each other; the corotation device 202-2 deployed in the traffic direction 312 is used for controlling the traffic light group 203-2 deployed in the traffic direction 312, and the corotation device 202-2 and the traffic light group 203-2 can be considered to be associated with each other; the case of the traffic orientation 313 and the traffic orientation 314 may be similar.

In practical application, the intersection can be a T-shaped intersection or other intersection besides an intersection.

In addition, the traffic light group comprises an indicator light for pedestrians (comprising a red light and a green light), or the traffic light group comprises an indicator light for vehicles (comprising a red light, a green light and a yellow light), or the traffic light group comprises an indicator light for pedestrians (comprising a red light and a green light) and an indicator light for vehicles (comprising a red light, a green light and a yellow light).

Optionally, the coordination and rotation device in any passing direction is specifically configured to control the traffic light group disposed in the same passing direction through a level change of an electric wire, and one electric wire is used to control one light in the traffic light group. For example, if the traffic light group includes a red light, a green light, and a yellow light, the wire connected to the red light of the corotation device may be labeled as wire 1, the wire connected to the green light may be labeled as wire 2, and the wire connected to the yellow light may be labeled as wire 3, then the corotation device may enable the red light by providing a high level (e.g., 220v hot wire) through wire 1, or enable the green light by providing a high level (e.g., 220v hot wire) through wire 2, or enable the yellow light by providing a high level (e.g., 220v hot wire) through wire 3.

In the embodiment of the application, the corotation equipment and the traffic light group in the same passing direction can form integrated equipment, namely the corotation equipment and the traffic light group are two different parts in one hardware equipment (namely one hardware product); of course, two different hardware devices (i.e., two different hardware products) may be provided.

In the embodiment of the present application, the traffic signal controller 201 communicates with each of the cooperative apparatuses 202 through a network.

Alternatively, the network may be an optical communication network, for example, an optical fiber is disposed between the traffic signal controller 201 and each of the corotation devices 202, and the optical communication network is constructed based on an optical network unit ONU network or an ethernet network. As shown in fig. 5, fig. 5 is a schematic view illustrating a scenario in which the traffic signal controller 201 and the cooperative equipment 202 communicate with each other through an optical communication network, and a communication device (or a communication module) 503 may be disposed on or near the traffic signal controller 201, and a communication device (or a communication module) 504 may be disposed on or near the cooperative equipment 202, and an optical fiber may be connected between the two communication devices, so as to support the traffic signal controller 201 and the cooperative equipment 202 to communicate with each other. In addition, when the communication is performed through the optical communication network, an ETH protocol or a 485 protocol may be specifically used for the communication.

Alternatively, the network may be a wireless network, and the wireless network may be specifically a wireless fidelity (wifi) network, a fourth Generation mobile communication network (4G), a fifth Generation mobile communication network (5G), and so on.

In addition, optionally, a power line can be provided from the traffic signal controller to each direction, and the power line is used for providing power required by the running of the traffic signal controller and the traffic light group for the corotation equipment and the traffic light group in the corresponding traffic direction. Generally, if there is an intersection, then four traffic directions can be provided with one power line each, i.e. four power lines in total. Therefore, if the traffic signal controller and the corotation equipment are communicated through the optical communication network, the traffic signal controller only needs to be provided with one optical fiber and one power line to one passing direction; if the traffic signal controller and the corotation equipment communicate through the wireless network, then the traffic signal controller to a current position only need dispose a power cord can, for traditional wiring mode, the wiring mode of this application is simpler, therefore the construction, and the maintenance cost has all been showing and has been reduced.

In an alternative scheme, as shown in fig. 2, the traffic signal control system 20 may further include a Network Video Recorder (NVR) 205, where the NVR205 is configured to receive, store, manage, and the like a digital Video stream transmitted by the Network camera 206 through a Network, and the content recorded by the digital Video stream is usually a road condition near an intersection, and can be used to analyze whether speeding occurs, whether a traffic accident occurs, whether a red light running behavior occurs, and the like. Optionally, NVR205 uses the same network as network camera 206 and as the network between the traffic signal controller and the corotation device.

Referring to fig. 6, fig. 6 is a traffic signal control method according to an embodiment of the present invention, which may be implemented based on the architecture shown in fig. 2, and the method includes, but is not limited to, the following steps:

step S601: the traffic signal controller generates control information.

Specifically, the traffic signal controller may generate the control information under artificial control, for example, when a traffic manager coordinates the passing of vehicles and pedestrians in different passing directions according to the intersection of the intersection, the traffic signal controller may be operated on the traffic signal controller, or operated on a computer by a remote control method, or operated by other methods, and as a result, the traffic signal controller generates the control information. As another example, the traffic signal controller has a corresponding algorithm configured therein, from which the traffic signal controller decides when to generate control information indicative of what operation. The control information is used for controlling the traffic light groups at the intersection, so that vehicles and pedestrians at different passing directions at the intersection can pass in order according to the on-off time of the traffic light groups.

Step S602: and the traffic signal controller sends control information to the first corotation equipment.

Specifically, the traffic signal controller packages the control information in a certain format, and sends the control information to the network through a corresponding communication protocol (such as an ETH port/485 port), and the like, and then the control information is transmitted to the corresponding corotation device through the network.

In the embodiment of the application, the traffic signal controller may send the control information to the network in a unicast or broadcast manner. For example, the broadcast is performed by using an ETH port protocol or a 485 port protocol.

The first cooperative apparatus is one of the at least one cooperative apparatus, and it can be understood that when the control information is sent in a unicast manner, the control information needs to carry a destination address (an IP address, or an MAC address, or identification information), and the network may determine, based on the destination address, to which cooperative apparatus the control information is specifically sent, that is, may identify the destination cooperative apparatus, where the destination cooperative apparatus is the first cooperative apparatus. When the control information is sent in a broadcast form, there are usually a plurality of cooperative apparatuses that actually receive the control information, and then the first cooperative apparatus here may be considered as one of the plurality of cooperative apparatuses, that is, the first cooperative apparatus is taken as an example for illustration, and the operation after the other cooperative apparatuses receive the control information is the same as the operation principle executed by the first cooperative apparatus, and therefore, the description is omitted.

Step S603: the first cooperative transmission equipment receives the control information.

Specifically, the first cooperative apparatus may decode the received control information to restore the original control information. It is understood that the control information originally generated by the traffic signal controller is usually encapsulated based on the relevant communication protocol in order to be successfully transmitted in the network, and then the decoding process of the first protocol conversion device is regarded as a decapsulation process.

Step S604: and the first cooperative rotating equipment controls the traffic light group associated with the first cooperative rotating equipment according to the control information.

For the unicast condition of control information, the control information is used for indicating the operation needing to be executed; therefore, the controlling, by the first cooperative transmission device, the traffic light group associated with the first cooperative transmission device according to the control information may specifically be: and the first cooperative rotation equipment controls the on-off of each lamp in the traffic light group associated with the first cooperative rotation equipment according to the control information.

In the case of control information broadcast, the control information includes identification information and operation information, where the identification information is used to indicate the object of control, and for example, the identification information may be an IP address or a MAC address of a certain cooperative apparatus, or other information that can be distinguished from another cooperative apparatus, and so on. The operation information is used for indicating the operation needing to be executed. The first cooperative transmission device controls the traffic light group associated with the first cooperative transmission device according to the control information, and the control information may specifically be: the first cooperative conversion equipment determines whether the control object is the traffic light group associated with the first cooperative conversion equipment or not according to the identification information (for example, if the identification information carried in the control information is the same as the self identity, the control object is the traffic light group associated with the control object, otherwise, the control object is not the traffic light group associated with the control object); if so, the first cooperative rotation equipment controls the on-off of each lamp in the traffic light group associated with the first cooperative rotation equipment according to the operation information. Optionally, if not, the first cooperative apparatus discards the control information, that is, does not perform any control based on the control information any more.

In this embodiment, the operation to be performed indicated by the operation information or the operation to be performed indicated by the control information actually indicates how to control on/off of each light in the traffic light group, for example, if the traffic light group associated with the first turning device includes a red light, a green light, and a yellow light, the operation information or the control information indicates which light(s) of the red light, the green light, and the yellow light are (are) to be currently controlled to be on and which light(s) are (are) to be controlled to be off.

In an alternative, the first turning device is specifically configured to control the associated traffic light group through a level change of the wire, and one wire is configured to control one light in the traffic light group, for example, if the traffic light group associated with the first turning device includes one red light, one green light and one yellow light, the wire connected with the red light of the first turning device can be marked as wire 1, the wire connected with the green light can be marked as wire 2, and the wire connected with the yellow light can be marked as wire 3, then the first turning device can provide a high level (such as 220v live wire, or 36 v, or other specifications) through wire 1 to enable the red light, or provide a high level (such as 220v live wire, or 36 v, or other specifications) through wire 2 to enable the green light, or provide a high level (such as 220v live wire, or 36 volts, or other specification) to enable the yellow light.

In the method described in fig. 6, each passing position from the traffic signal controller to the intersection can transmit the control requirement to each passing position only by configuring a communication network (for example, an optical fiber network), and the cooperative rotation device of each passing position can control the traffic light group of the same passing position after receiving the control information according to the communication network. According to the traffic signal control method, the live wire corresponding to each lamp in the traffic light group does not need to be led out from the traffic signal controller to each passing position, the number of lines led out from the traffic signal controller is obviously reduced, and the line delivery deployment efficiency and the maintenance efficiency are improved.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a traffic signal control system 70 according to an embodiment of the present invention, where the traffic signal control system 70 includes a traffic signal controller 701, a detection device 704, at least one cooperative rotation device 702, and at least one traffic light group 703, where:

when there are multiple turning-assistant devices 702, the multiple turning-assistant devices 702 can be deployed at different passing directions of the same intersection, as fig. 3 illustrates four passing directions of an intersection, namely a passing direction 311, a direction 312, a passing direction 313 and a passing direction 314, wherein the four directions can deploy different turning-assistant devices 702 and traffic light groups 703 respectively. The turning-assistant device 702 deployed at any passing direction of the intersection is used for controlling the traffic light group 703 deployed at the same passing direction. As shown in fig. 8, the cooperative rotating apparatus 702-1 disposed in the passing direction 311 is used to control the traffic light group 703-1 disposed in the passing direction 311, and the cooperative rotating apparatus 702-1 and the traffic light group 703-1 may be considered to be associated with each other; the corotation device 702-2 deployed in the passing position 312 is used for controlling the traffic light group 703-2 deployed in the passing position 312, and the corotation device 702-2 and the traffic light group 703-2 can be considered to be associated with each other; the case of the traffic orientation 313 and the traffic orientation 314 may be similar.

In this embodiment, the traffic signal controller 701 includes a plurality of wires, each wire being respectively used for controlling one light of the at least one traffic light group; for example, if there are 4 traffic directions at the intersection, each traffic direction includes a traffic light group (including a red light, a green light and a yellow light) indicating the traffic direction, the traffic signal controller 701 needs to draw 12 live wires, and when the live wire corresponding to a certain light in a certain traffic light group is powered on, the light is turned on. However, in the embodiment of the present application, although a plurality of wires are led out from the traffic signal controller 701, the plurality of wires are not directly connected to each passing direction of the intersection, but are connected to the detection device 704, and the detection device 704 can know which lamp in the traffic light group in which passing direction needs to be enabled according to the power-on condition of each live wire, so as to generate the control information for controlling the on and off of the traffic light, and the control information is subsequently sent to the steering assistant device 702 by the detection device 704.

The detection device 704 is deployed near the traffic signal controller, for example, within 10 meters, or within 2 meters, or within 1 meter, or some other close distance. In addition, the detection device 704 may also be deployed in a hardware device with the traffic signal controller (i.e., constitute a hardware product).

The detection device 704 communicates with each of the coordinating devices 702 over a network.

Alternatively, the network may be an optical communication network, for example, an optical fiber is disposed between the detection device 704 and each of the cooperative devices 702, and the optical communication network is constructed based on an optical network unit ONU network or an ethernet network. As shown in fig. 9, fig. 9 is a schematic view illustrating a scenario in which the detection device 704 communicates with the cooperative apparatus 702 through an optical communication network, where a communication device (or a communication module) 903 may be disposed on or near the detection device 704, and a communication device (or a communication module) 904 may be disposed on or near the cooperative apparatus 702, and an optical fiber is connected between the two communication devices, so as to support the detection device 704 to communicate with the cooperative apparatus 702. In addition, when the communication is performed through the optical communication network, an ETH protocol or a 485 protocol may be specifically used for the communication.

In addition, optionally, a power line can be provided from the detection device (or the traffic signal controller) to each direction for providing power required by the running of the corotation device and the traffic light group in the corresponding traffic direction. Generally, if there is an intersection, then four traffic directions can be provided with one power line each, i.e. four power lines in total. Therefore, if the detection device (or the traffic signal controller) and the corotation device communicate through the optical communication network, the detection device (or the traffic signal controller) only needs to be provided with one optical fiber and one power line to one passing direction; if the detection equipment (or the traffic signal controller) and the corotation equipment are communicated through a wireless network, the detection equipment (or the traffic signal controller) only needs to be provided with one power line to a passing direction, and compared with a traditional wiring mode, the wiring mode is simpler, so that the construction cost and the maintenance cost are obviously reduced.

In an alternative scheme, as shown in fig. 7, the traffic signal control system 70 may further include a Network Video Recorder (NVR) 705, where the NVR705 is configured to receive, store, manage, and the like a digital Video stream transmitted by the Network camera 206 through a Network, and the content recorded by the digital Video stream is usually a road condition near an intersection, and can be used to analyze whether speeding occurs, whether a traffic accident occurs, whether a red light running behavior occurs, and the like. Optionally, the NVR705 uses the same network as the network between the network camera 706 and the network between the traffic signal controller and the cooperative equipment.

Referring to fig. 10, fig. 10 is a traffic signal control method according to an embodiment of the present invention, which may be implemented based on the architecture shown in fig. 7, and the method includes, but is not limited to, the following steps:

step S1001: the detection device converts the level signals on the plurality of wires of the traffic signal controller into control information.

Specifically, the traffic signal controller can set one or more of a plurality of wires (such as a live wire, and in addition, the wires can also exist in the form of pins) to be at a high level under the condition of artificial control, for example, when a traffic manager coordinates the passing of vehicles and pedestrians in different passing directions according to the intersection of the intersection, the traffic signal controller can be operated on a computer or operated in a remote control mode on the computer or operated in other modes, and the level of one or more of the plurality of wires of the traffic signal controller is changed as a result of the operation. For another example, the traffic signal controller is configured with a corresponding algorithm, according to which the traffic signal controller decides which wire or wires are to be brought high at what time.

Accordingly, the detection device can detect the level change of each wire of the traffic signal controller in real time or according to a certain rule, and the detection device can know which lamp in the traffic light group in which traffic direction needs to be enabled according to the power-on condition of each wire, so that control information for controlling the on and off of the traffic light is generated, and the process is the process of converting the level signal into the control information.

Step S1002: and the detection equipment sends control information to the first coordination equipment.

Specifically, the detection device packages the control information in a certain format, and sends the control information to the network through a corresponding communication protocol (such as an ETH port/485 port), and the like, and then the control information is transmitted to the corresponding corotation device through the network.

In this embodiment, the detection device may send the control information to the network in a unicast or broadcast manner. For example, the broadcast is performed by using an ETH port protocol or a 485 port protocol.

Step S1003: the first cooperative transmission equipment receives the control information.

Specifically, the first cooperative apparatus may decode the received control information to restore the original control information. It is understood that the control information originally generated by the detection device is usually encapsulated based on the relevant communication protocol in order to be successfully transmitted in the network, and then the decoding process of the first coordination device is regarded as a decapsulation process.

Step S1004: and the first cooperative rotating equipment controls the traffic light group associated with the first cooperative rotating equipment according to the control information.

In the method described in fig. 10, each passing position from the traffic signal controller to the intersection only needs to configure a communication network (e.g., an optical fiber network) to transmit the control requirement to each passing position, and the cooperative switching device of each passing position can control the traffic light set of the same passing position after receiving the control information according to the communication network. According to the traffic signal control method, the live wire corresponding to each lamp in the traffic light group does not need to be led out from the traffic signal controller to each passing position, the number of lines led out from the traffic signal controller is obviously reduced, and the line delivery deployment efficiency and the maintenance efficiency are improved.

In the embodiment of the present application, the traffic signal controller in the architecture shown in fig. 2 is completely different from the traffic signal controller in the prior art, so the architecture shown in fig. 2 is a great improvement over the prior art; the traffic signal controller in the architecture shown in fig. 7 may be the same as the traffic signal controller in the prior art, but compatibility with the existing traffic signal controller is achieved by configuring a detection device to convert the level signal of the traffic signal controller.
