Specific embodiment

To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention Formula is described in further detail.

The embodiment of the invention provides a kind of method for controlling traffic lights, the executing subject of this method is server.Wherein, The server can be the server with control traffic lights function, which can be a server, be also possible to one A server group being made of letter control server, board knowledge server, security server.Processing can be set in the server Device, memory and transceiver, processor can be used for controlling the relevant treatment of traffic lights, and memory can be used for storing following places The data for needing and generating during reason, transceiver can be used for sending and receiving data.

Below in conjunction with specific embodiment, process flow shown in FIG. 1 is described in detail, content can be as Under:

Step 101, the license plate number in the image that each image capturing device for detecting crossing takes is obtained, wherein inspection Survey the previous crossing that crossing is the starting point at the crossing or security travel route on the security travel route of security fleet.

Wherein, security travel route can be security fleet traveling, and need to be implemented the route of security task, the first detection Crossing can be the crossing for being provided with image capturing device.

In an implementation, security travel route, security fleet the license plate number of leading vehicle can be server in security Know in the driving process of fleet, is also possible to pre-stored.Subsequent statement carries out scheme for pre-stored It is described in detail.Specifically, staff can be in advance by the row of security fleet after determining the security travel route of security fleet Information is sailed to be configured.Specifically, staff can be stored in advance each crossing on security travel route crossing mark and The crossing at the previous crossing of the starting point for the security travel route that security fleet can pass through identifies (wherein, the embodiment of the present invention The detection crossing can be the section position for being provided with traffic lights, wherein be also provided with image in each detection crossing Image capturing device is provided in filming apparatus, or part detection crossing, part is not provided with image taking in detection crossing Device, detection crossing can be T shape crossing, Y shape crossing, cross crossing, X-shaped crossing etc.), driving direction, traveling lane, friendship Lead to the corresponding relationship and the license plate number of leading vehicle, the license plate number of tail of the queue vehicle, travel speed of beacon light knowledge and phase etc. Deng, wherein the previous crossing of the starting point for the security travel route that security fleet can pass through, which can be, is provided with bayonet or electricity The crossing of sub- police.

The bayonet or electronic police at each crossing can constantly be shot to by the vehicle at the crossing, in turn, can be with The image of shooting is sent to server, after server receives image, image recognition processing can be carried out, determined in image The license plate number of vehicle.Alternatively, after the bayonet or electronic police at each crossing take image image recognition can be carried out to it Processing, the license plate number for the vehicle that will identify that are sent to server.During security task execution, whenever server determines (wherein, image capturing device can be crossing opposite side in security fleet driving direction to the image capturing device at each detection crossing out Image capturing device) after license plate number in the image that takes, server can get the image taking dress at each crossing The license plate number that (bayonet or electronic police) takes is set, in turn, can detecte the image capturing device shooting at each detection crossing To license plate number whether be pre-stored security fleet leading vehicle license plate number.That is, in security task In implementation procedure, it can continue to obtain the license plate number that the image capturing device at each detection crossing takes, it is each whenever getting When the license plate number that the image capturing device at detection crossing takes, server can be detected the image taking dress at each detection crossing Set the license plate number that takes whether be pre-stored security fleet leading vehicle license plate number.

In addition, the feelings of server, the server group that security server forms are known by letter control server, board for server Condition, security server can be pre-configured with above-mentioned driving information, and in turn, the crossing mark that can will test crossing is sent to board knowledge Server.In this way, after board knows the license plate number that server identifies that the image capturing device at each detection crossing takes, it can To send it to security server, security server receives the license plate number that the image capturing device at each detection crossing takes After code, it can detecte whether the license plate number that each image capturing device for detecting crossing takes is pre-stored security fleet Leading vehicle license plate number.Alternatively, security server can also send the license plate number of the leading vehicle of security fleet Server is known to board.In this way, whenever board knowledge server identifies the license plate number that the image capturing device at each detection crossing takes After code, it can directly detect whether the license plate number that each image capturing device for detecting crossing takes is pre-stored security The license plate number of the leading vehicle of fleet.

Step 102, when detecting that the license plate number in the image that the image capturing device at the first detection crossing takes is The license plate number of the leading vehicle of pre-stored security fleet, and the first detection crossing be except on security travel route last When any detection crossing except a crossing, first driving direction of the security travel route at the second detection crossing is obtained, In, the second detection crossing is the latter crossing at the first detection crossing on security travel route.

Wherein, the second detection crossing can be the crossing for being provided with traffic lights, and figure can be set in the second detection crossing As filming apparatus, image capturing device can also be not provided with.

In an implementation, when server detects the license plate number that the image capturing device at the first detection crossing takes for peace When protecting the license plate number of the leading vehicle of fleet (when detecting the leading vehicle driving of security fleet to the first detection crossing, Wherein, the license plate number of leading vehicle can be pre-stored, is also possible to leading vehicle and is sent to clothes in the process of moving Business device), can further detect whether the first detection crossing is appointing in addition to the last one crossing on security travel route One detection crossing, if the first detection crossing is any detection crossing in addition to the last one crossing on security travel route, Then driving direction (can be described as first driving direction) of the available security travel route of server at the second detection crossing, i.e., Driving direction when the available security fleet of server is by the second detection crossing, wherein the second detection crossing can be peace Protect next crossing at the first detection crossing on travel route.For example, according to traveling sequence, crossing on security travel route according to Secondary crossing 1 (being the starting point of security travel route), crossing 2, crossing 3, crossing 4, crossing 5, the previous crossing at crossing 1 is Crossing 0, when the first detection crossing is crossing 0, the second detection crossing is crossing 1.

Server, which is known, for board detects whether the license plate number that each image capturing device for detecting crossing takes is preparatory The case where license plate number of the leading vehicle of the security fleet of storage, when board knows the image that server detects the first detection crossing When the license plate number that filming apparatus takes is the license plate number of security fleet, the security vehicle can be sent to security server The leading vehicle of team reaches the notice at the first detection crossing, and the leading vehicle that security server receives security fleet reaches first After the notice for detecting crossing, can detect whether the first detection crossing is except on security travel route in the way of above-mentioned tell about Any detection crossing except the last one crossing, if the first detection crossing is except the last one crossing on security travel route Except any detection crossing, then the available security travel route of security server second detection crossing at traveling side To.

Step 103, the traffic lights at the second detection of control crossing is in prevailing state in the first driving direction.

In an implementation, after server gets the first driving direction, it can control the traffic lights at the second detection crossing It (such as can be by the corresponding traffic lights in lane where security fleet in the first driving direction in prevailing state in one driving direction On be locked in green light phase), and control second detection crossing traffic lights on the direction except the first driving direction in prohibit Only state (for example traffic lights can be locked in red light phase on the direction except the first driving direction), as shown in Fig. 2, its In, the direction except the first driving direction can be different from the first driving direction, and with the conflicting side of the first driving direction To for example, the first driving direction is direction (or North and South direction) from south to north, then server can control traffic lights in the South and the North To be in prevailing state, traffic lights east-west direction (from east to west, from west to east), from west northwards direction, from east orientation south to In forbidden state.In this way, security fleet travel to second detection crossing when, it is ensured that second detection crossing first traveling Prevailing state is on direction, the direction except the first driving direction is in forbidden state, and fleet smoothly passes through so as to security Second detection crossing.

Specifically, server can send current notice to the traffic light controller at the second detection crossing, wherein current logical The first driving direction can be carried in knowing can control traffic lights first after traffic light controller receives current notice It is in prevailing state in driving direction, forbidden state is on the direction except the first driving direction.

The case where server, the server group that security server forms are known by letter control server, board for server, peace It protects after server gets the first driving direction, the traffic lights at the second detection of control crossing can be sent to letter control server the The notice of prevailing state is in one driving direction can forward it to the second detection after letter control server receives notice The traffic light controller at crossing can be by control traffic lights in the first traveling side after traffic light controller receives current notice It is in prevailing state upwards, forbidden state is on the direction except the first driving direction.

Optionally, the trigger condition that the traffic lights at crossing is detected based on control second is different, and the processing mode of step 103 can With varied, following present several feasible processing modes:

Mode one, before detecting that the license plate number in the image that the image capturing device at the first detection crossing takes is While the license plate number of guide-car, that is, the traffic lights for controlling the second detection crossing is in current shape in the first driving direction State.

In an implementation, when server detects the license plate in image that the image capturing device at the first detection crossing takes Number be the license plate number of leading vehicle when, i.e. the traffic lights at controllable second detection crossing is in the first driving direction Prevailing state.

Mode two can also be in leading one timing of vehicle driving after detecting leading vehicle driving to the first detection crossing After length, then the traffic lights at the second detection crossing is controlled, correspondingly, the treatment process of step 103 can be such that according to before acquisition The travel speed of guide-car, the first detection crossing to second detection the distance between crossing value calculate leading vehicle described the One detection crossing to the third between the second detection crossing travels duration, travels duration setting fourth line according to third and sails duration simultaneously Start timing, fourth line sails duration and travels duration equal or shorter than third；When timing duration, which is equal to the fourth line, sails duration, The traffic lights at the second detection of control crossing is in prevailing state in first driving direction.

In an implementation, server determines that the license plate number that the image capturing device at the first detection crossing takes is leading After the license plate number of vehicle, the travel speed of available leading vehicle, the first detection crossing are between the second detection crossing (wherein, travel speed, distance value can be that server is pre-stored, and travel speed is also possible to according to practical row to distance value Obtained in real time during sailing by speed measuring device), in turn, can according to the first of acquisition detection crossing to second detection crossing it Between distance value and travel speed (general security fleet remain a constant speed on security travel route traveling), guide-car before calculating It, in turn, can will at the first detection crossing to the traveling duration (can be described as third traveling duration) between the second detection crossing Third traveling duration is subtracted each other with pre-stored second preset duration threshold value, is obtained fourth line and is sailed duration and start timing, wherein Second preset duration threshold value may be greater than or the lesser numerical value equal to 0, when timing duration, which is equal to fourth line, sails duration, clothes Business device can control the traffic lights at the second detection crossing in the first driving direction in prevailing state, the first driving direction it Forbidden state is on outer direction.For example, third traveling duration is 50 seconds, the second preset duration threshold value is 20 seconds, then services Device can calculate third traveling duration and the difference of the second preset duration threshold value obtains fourth line and sails duration (as 30 seconds) and open Beginning timing, when timing duration reaches 30 seconds, server can control the traffic lights at the second detection crossing in the first driving direction It is upper to be in prevailing state, forbidden state is on the direction except the first driving direction.

Optionally, server can also cancel the control of the traffic lights to the second detection crossing, accordingly at the appropriate time , treatment process can be such that during the traffic light control to the second detection crossing, when detecting the second detection crossing The image that takes of image capturing device in license plate number when being the license plate number of tail of the queue vehicle of security fleet, cancel pair The control of the traffic lights at the second detection crossing.

In an implementation, after server is to the traffic light control at the second detection crossing, it can detecte the tail of the queue vehicle of security fleet The second detection crossing whether is passed through, wherein be provided with image capturing device in the second detection crossing, and be provided with traffic Lamp, when tail of the queue vehicle has passed through the second detection crossing, server can cancel the control of the traffic lights to the second detection crossing. Specifically, server it is lasting obtain it is each detection crossing image capturing device take license plate number during, whenever When getting the license plate number that each image capturing device for detecting crossing takes, the image taking at each detection crossing can detecte The license plate number that device takes whether be pre-stored security fleet tail of the queue vehicle license plate number, when detecting second The license plate number that the image capturing device at detection crossing takes is the license plate number of the tail of the queue vehicle of pre-stored security fleet When code, the control of the traffic lights to the second detection crossing can be cancelled, at this point, the working mechanism that traffic lights is back to normal, such as Fig. 3 It is shown.In addition, server can also be pre- in the license plate number for detecting that the image capturing device at the second detection crossing takes The license plate number of the tail of the queue vehicle of the security fleet first stored, and after preset duration, cancel the friendship to the second detection crossing The control of logical lamp.

Optionally, for guarantee second detection crossing image capturing device fail the feelings for correctly taking tail of the queue vehicle Under condition, the control of the traffic lights to the second detection crossing can be cancelled in time, server can also be handled as follows: to the During the traffic light control at two detection crossings, when the image for detecting that the image capturing device at the first detection crossing takes In license plate number when being the license plate number of tail of the queue vehicle of security fleet, according to the traveling of the tail of the queue vehicle of acquisition speed Degree, the first detection crossing to second detection the distance between crossing value calculate tail of the queue vehicle at the first detection crossing to the The first traveling duration between two detection crossings according to first the second traveling duration of traveling duration setting and starts timing, and second Duration is travelled equal or longer than the first traveling duration；When timing duration is equal to the second traveling duration, cancel to the second detection road The control of the traffic lights of mouth.

In an implementation, during the traffic light control to the second detection crossing, when server determines tail of the queue vehicle (for example, when detecting the vehicle in the image that the image capturing device at the first detection crossing takes when reaching the first detection crossing When trade mark code is the license plate number of tail of the queue vehicle), it can also be according to the travel speed of the tail of the queue vehicle of acquisition, the first detection crossing To the distance between the second detection crossing value, tail of the queue vehicle is calculated at the first detection crossing to first between the second detection crossing Duration is travelled, in turn, the first traveling duration can be added (wherein, the first preset duration threshold value with the first preset duration threshold value Can be it is pre-stored be greater than or equal to 0 lesser numerical value), obtain the second traveling duration, and it is (main to start timing If being counted since the first detection crossing to the practical duration that the second detection crossing travels to tail of the queue vehicle).To During the traffic light control at two detection crossings, when detecting that timing duration is equal to the second traveling duration, it can cancel pair The control of the traffic lights at the second detection crossing.That is, server has been cancelled when timing duration is equal to the second traveling duration If the control for the traffic lights for detecting crossing to second, this processing can be carried out no longer, when timing duration is equal to second when driving When long, when the traffic lights at the second detection crossing is also in state of a control, the control of the traffic lights to the second detection crossing can be cancelled System.

In addition, in the present solution, server can use above two mode, traffic of the cancellation to the second detection crossing simultaneously The control of lamp.

Optionally, in the case where upper detection crossing is not provided with image capturing device, server can also be according to row Duration is sailed, at the time of determining the traffic lights at control current detection crossing, correspondingly, concrete processing procedure can be such that if the Two detection crossings are not provided with image capturing device, and the second detection crossing is not the last one crossing on security travel route, Then according to the travel speed of the leading vehicle of acquisition, the first detection crossing to the distance between the second detection crossing value, before calculating Guide-car sails duration at the first detection crossing to the fifth line between the second detection crossing, or according to the leading vehicle of acquisition Travel speed, the first detection crossing to the distance between third detection crossing value, calculate leading vehicle first and detect crossing extremely Third detects the 6th traveling duration between crossing, and third detection crossing is the latter of the second detection crossing on security travel route A crossing sails the 7th traveling duration of duration setting according to fifth line and starts timing, and the 7th traveling duration is equal or shorter than the 5th Duration is travelled, or according to the 8th traveling duration of the 6th traveling duration setting and starts timing, the 8th traveling duration is equal to or short Duration is travelled in the 6th；When timing duration is equal to the 7th traveling duration or the 8th traveling duration, security travel route is obtained the The second driving direction at three detection crossings；The traffic lights for controlling third detection crossing is in current shape in the second driving direction State.

Wherein, third detection crossing can be the crossing for being provided with traffic lights, and figure has can be set in crossing in third detection As filming apparatus, image capturing device can also be not provided with.

In an implementation, when detecting that license plate number that the image capturing device at the first detection crossing takes is to be stored in advance Security fleet leading vehicle license plate number, and the first detection crossing be except on security travel route the last one crossing it When outer any detection crossing, it can also judge whether the second detection crossing is provided with image capturing device and the second detection road It mouthful is the last one crossing on security travel route, if the second detection crossing is not provided with image capturing device, and the Two detection crossings are not the last one crossings on security travel route, then server can be according to the traveling of the leading vehicle of acquisition Speed, the first detection crossing to the distance between the second detection crossing value, calculate leading vehicle at the first detection crossing to second Fifth line between detection crossing sails duration, in turn, fifth line can be sailed to duration and third preset duration threshold value subtracts each other (its In, third preset duration threshold value can be it is pre-stored be greater than or equal to 0 lesser numerical value), obtain the 7th traveling duration And start timing.In timing course, server can detecte the size relation of the 7th traveling duration and timing duration, work as detection When being equal to the 7th traveling duration to timing duration, the available security travel route of server detects second at crossing in third Driving direction, wherein third detection crossing is next crossing at the second detection crossing on security travel route.That is, working as According to timing duration, when detecting that leading vehicle will be travelled to the second detection crossing, the available security of server travels road Second driving direction of the line at third detection crossing.After getting the second driving direction, server can control third detection The traffic lights at crossing is in prevailing state in the second driving direction, and forbidden shape is on the direction except the second driving direction State, wherein the direction except the second driving direction can be different from the second driving direction, and mutually conflict with the second driving direction Direction.

Alternatively, if the second detection crossing is not provided with image capturing device, and the second detection crossing is not security traveling The last one crossing on route, then server can also reach the traveling duration that third detects crossing by calculating leading vehicle, Control the traffic lights at third detection crossing.Specifically, the travel speed of the available leading vehicle of server, the first detection crossing It, in turn, can travel speed according to the leading vehicle of acquisition, the first detection crossing to third detection the distance between crossing value To the distance between third detection crossing value, leading vehicle is calculated at the first detection crossing to the 6th between third detection crossing Duration is travelled, in turn, the 6th traveling duration and the 4th preset duration threshold value can be subtracted each other into (wherein, the 4th preset duration threshold value Can be it is pre-stored be greater than or equal to 0 lesser numerical value), obtain the 8th traveling and duration and start timing.In timing Cheng Zhong, server can detecte the 8th traveling duration and timing duration size relation, when detect timing duration be equal to the 8th When travelling duration, second driving direction of the available security travel route of server at third detection crossing.Get After two driving directions, the traffic lights that server can control third detection crossing is in prevailing state in the second driving direction, Forbidden state is on the direction except the second driving direction.

That is, server can determine the preceding guide-car of security fleet according to the image capturing device at each detection crossing The detection crossing being currently located, can also be each to detect the distance between crossing value with travel speed according to the pre-stored data, determines Traveling duration of the leading vehicle between each detection crossing according to calculated traveling duration, and is determined leading in turn Position where vehicle, at the time of estimating leading each detection crossing of vehicle arrival, thus, trigger the server is to each detection crossing Traffic lights is controlled.In this way, at the time of server uses two methods to determine that leading vehicle reaches certain detection crossing simultaneously, from And the phenomenon that security task can not be executed in the case where image capturing device being not provided with to avoid certain detection crossing appearance.

Optionally, in the case where the second detection crossing and third detection crossing are not provided with image capturing device, clothes It is engaged in the control of traffic lights that device can be cancelled according to timing duration to third detection crossing, correspondingly, concrete processing procedure can be with It is as follows: if third detection crossing is not provided with image capturing device, to detect the image capturing device at the first detection crossing When the license plate number in image taken is the license plate number of the tail of the queue vehicle of security fleet, according to the tail of the queue vehicle of acquisition Travel speed, the first detection crossing to the distance between third detection crossing value, calculate tail of the queue vehicle first and detect crossing extremely Third detects the 9th traveling duration between crossing, according to the tenth traveling duration of the 9th traveling duration setting and starts timing, the Ten traveling durations are equal or longer than the 9th traveling duration；During the traffic light control to third detection crossing, work as timing When duration is equal to the tenth traveling duration, cancel the control of the traffic lights to third detection crossing.

In an implementation, it if the second detection crossing and third detection crossing are not provided with image capturing device, detects The license plate number in image taken to the image capturing device at the first detection crossing is the vehicle of the tail of the queue vehicle of security fleet When trade mark code, at the time of can determining that tail of the queue vehicle reaches third detection crossing.Specifically, when detect that tail of the queue vehicle reaches the When one detection crossing, server can detect road according to the travel speed of the tail of the queue vehicle of acquisition, the first detection crossing to third The distance between mouth value calculates tail of the queue vehicle at the first detection crossing to the 9th between third detection crossing and travels duration, into And the 9th timing duration can be added with the 5th preset duration threshold value (wherein, the 5th preset duration threshold value may be greater than or Lesser numerical value equal to 0), the tenth traveling duration is obtained, and start timing.In timing course, server can detecte meter The size of the traveling duration of Shi Shichang and the tenth, during the traffic light control to third detection crossing, when timing duration etc. When the tenth traveling duration, server can cancel the control of the traffic lights to third detection crossing.

The security server judges whether first detection crossing is except the last one crossing on the security travel route Except any detection crossing obtain the security travel route at the second detection crossing and when the judgment result is yes First driving direction, wherein second detection crossing is the latter of first detection crossing on the security travel route A crossing；

The security server sends the traffic lights at control second detection crossing described first to the letter control server The notice of prevailing state is in driving direction；

The traffic lights that the letter control server controls second detection crossing is in current shape in first driving direction State.

14. system according to claim 13, which is characterized in that the board knows server and judges second detection crossing The image that takes of image capturing device in license plate number whether be the security fleet tail of the queue vehicle license plate number, And when the judgment result is yes, the second detection crossing is reached to the tail of the queue vehicle that the security server sends the security fleet Notice；

The security server is during the traffic light control to second detection crossing, when receiving the security vehicle When the tail of the queue vehicle of team reaches the notice at the second detection crossing, sends and cancel to second detection road to letter control server The notice of the control of the traffic lights of mouth；

The letter control server cancels the control of the traffic lights to second detection crossing.

15. system according to claim 13, which is characterized in that if second detection crossing is not provided with image bat Device is taken the photograph, and second detection crossing is not the last one crossing on the security travel route, then the security server According to the travel speed of the leading vehicle of acquisition, the first detection crossing to the distance between the second detection crossing value, calculate The leading vehicle sails duration at the first detection crossing to the fifth line between the second detection crossing, or according to acquisition The travel speed of the leading vehicle, the first detection crossing to the distance between third detection crossing value, calculate the preceding guide-car At the first detection crossing to the 6th traveling duration between third detection crossing, third detection crossing is the peace The 7th traveling duration of duration setting is sailed according to the fifth line in the latter crossing for protecting second detection crossing on travel route And starting timing, the 7th traveling duration sails duration equal or shorter than the fifth line, or when driving according to the described 6th Long the 8th traveling duration of setting simultaneously starts timing, and the 8th traveling duration is equal or shorter than the 6th traveling duration；Work as meter When Shi Shichang is equal to the 7th traveling duration or the 8th traveling duration, obtains the security travel route and detected in the third The second driving direction at crossing；

The security server sends the traffic lights for controlling third detection crossing described second to the letter control server The notice of prevailing state is in driving direction；

The traffic lights that the letter control server controls third detection crossing is in current shape in second driving direction State.
