Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The special vehicle escort method and the special vehicle escort device are suitable for the situation that the special vehicle escort is carried out to improve the passing efficiency of the special vehicle. The special vehicle convoy method provided by the present disclosure may be executed by a special vehicle convoy device, which may be implemented by software and/or hardware, and is specifically configured in an electronic device, where the electronic device may be a mobile terminal (such as a mobile phone, a tablet, etc.), a server, a computer, a vehicle-mounted device, a single chip, or other computing devices, and is not limited herein.
The special vehicle convoy method provided by the present disclosure is first explained in detail below.
Special vehicles such as fire-fighting vehicles, emergency vehicles, special service vehicles, emergency vehicles, etc. generally need higher traffic safety and traffic efficiency when performing tasks.
At present, when a special vehicle executes a task, the passing efficiency is generally improved by means of prompting a social vehicle to avoid emergently on a congested road section through operations such as lighting, whistling and the like. However, in this way, under the condition of excessive traffic congestion, since social vehicles are difficult to avoid, the special vehicles are still blocked, and the higher passing efficiency of the special vehicles cannot be well ensured.
To this end, the present disclosure provides a special vehicle convoy method, including: responding to a received convoy application instruction for the special vehicle, and generating a convoy path according to the convoy application instruction; acquiring the position information of the special vehicle; and controlling the annunciators at all intersections on the convoying path to indicate the traffic signals in the traffic direction of the convoying path through the signal control system according to the position information and the convoying path of the special vehicle.
The method can generate the convoy path according to the convoy initial position of the special vehicle and acquire the position information of the special vehicle when the convoy application is initiated by the special vehicle, so that the annunciators of all intersections on the special vehicle driving path are controlled according to the position of the special vehicle and the convoy path, and the annunciators in the driving direction of the special vehicle can indicate the traffic signals (such as the green light of the annunciators in the driving direction) when the special vehicle is about to drive to the corresponding intersections, so that the social vehicles at the corresponding intersections in the driving direction can rapidly pass, the social vehicle queue congestion is avoided, and the traffic efficiency of the special vehicle is improved.
Fig. 1 is a schematic flow chart of a special vehicle convoy method provided by the embodiment of the disclosure. As shown in fig. 1, the method may include the following S101-S103.
And S101, responding to the received convoy application instruction for the special vehicle, and generating a convoy path according to the convoy application instruction.
For example, the convoy application instruction for the special vehicle may be an convoy application instruction input by the user after directly inputting corresponding parameters (such as a convoy start position, a convoy end position, and the like).
For example, when the electronic device executing the method is a mobile terminal (such as a mobile phone, a tablet, etc.), a vehicle-mounted device, etc., a user may directly input corresponding parameters on the electronic device to initiate an escort instruction on the electronic device.
For another example, when the electronic device executing the method is a fixed device such as a computer or a server, a user may provide parameters (such as a convoy start position, a convoy end position, a vehicle number plate, etc.) corresponding to a convoy request to an operator of the electronic device through a device such as a telephone or a handheld radio, and then the operator inputs the corresponding parameters to the electronic device to initiate a convoy instruction on the electronic device.
Or the convoy application instruction for the special vehicle can also be a convoy application instruction sent by other equipment. For example, when the method is executed by an electronic device (e.g., a server, a mobile terminal, a computer, and other computing devices), a user may use a user terminal (e.g., a handheld terminal, a vehicle-mounted device, and the like) to perform operations, for example, after the user inputs parameters related to the convoy application on the user terminal, the user terminal generates a convoy application instruction and sends the convoy application instruction to the electronic device.
It should be noted that, a dedicated network connection may be used between the user terminal and the electronic device, thereby improving security. Of course, in practical application, a public network connection may also be adopted, which is not limited here.
The convoy application instruction can carry a number plate or type (such as fire fighting, special service, emergency) of a special vehicle. Then, the mapping relation between the special vehicle with the corresponding number plate or type and the preset convoying path is preset. Therefore, the manner of generating the convoy path according to the convoy application instruction can be that a preset convoy path corresponding to the special vehicle is determined based on the convoy application instruction, and the determined preset convoy path is used as the convoy path.
Of course, the convoy application instruction may also carry other parameters, so as to generate a corresponding convoy path according to the carried parameters, which is not limited herein.
And S102, acquiring the position information of the special vehicle.
When the electronic equipment for executing the method is vehicle-mounted equipment, handheld equipment and other equipment which moves along with the special vehicle, the position information of the electronic equipment can be directly used as the position information of the special vehicle.
Or, when the user is a convoy application instruction sent by a user terminal (such as a handheld terminal, a vehicle-mounted device, or the like), the location information of the user terminal may be used as the location information of the special vehicle, and the like, and this time is not limited, for example, a corresponding positioning device may be further provided on the special vehicle, so that the convoy application carries an IP or Mac address or the like of the corresponding positioning device, and then the location information of the corresponding positioning device is obtained to determine the location information of the special vehicle.
S103, controlling signalers at each intersection on the escort path to indicate a traffic signal in the traffic direction of the escort path through a signal control system according to the position information of the special vehicle and the escort path.
It should be noted that the signal control system is a system for controlling an intersection signal machine in the current traffic guidance system. The signal control system can control the signal indication of each signal connected thereto. For example, the traffic signal may be controlled to indicate a pass signal (i.e., a green light is illuminated), the traffic signal may be controlled to indicate a no-pass signal (i.e., a red light is illuminated), and so on.
The traffic signal indicates a traffic signal in the traffic direction of the escort path, the traffic signal indicates a traffic signal in the traffic direction, and the traffic signal indicates a no-go signal in other directions influencing the traffic direction of the escort path.
The electronic device executing the method may be connected to the signal control system through a dedicated network to improve security, or may also be connected to a public network, and may be wirelessly connected or wired (which may be set according to actual conditions, for example, when the electronic device is a handheld terminal, a vehicle-mounted device, or another device that moves along with a special vehicle, the electronic device may be wirelessly connected, or when the electronic device is another device, the electronic device may be in any of two ways), which is not limited herein.
It should be noted that, since different signal control systems may use different communication protocols, the corresponding communication protocols may be used to connect with corresponding signal control systems, and this is not limited herein. For example, the GA/T1049.2 protocol can be adopted to be connected with a signal control system and the like.
For example, when the signal control system controls the signal machine at each intersection on the convoying path to indicate the passing signal in the passing direction of the convoying path, the signal machine at the special vehicle convoying path in the passing direction can be controlled to indicate the passing signal, and the signal machine at the corresponding intersection which does not influence the passing direction of the special vehicle can be controlled to indicate the passing signal, so that the influence on the normal passing of the social vehicles is reduced. For example, when the traffic direction of the special vehicle is executed, the traffic signals of the straight-going direction of the special vehicle at the intersection, the opposite straight-going direction of the special vehicle and the right-turning direction of the traffic direction of the special vehicle are all used for indicating traffic signals, so that the normal traffic of the social vehicles which are opposite to the straight-going direction and the right-turning direction is not influenced.
Optionally, the convoy application instruction may carry a convoy start position and a convoy end position, so as to generate a convoy path according to the convoy application instruction, and the method may include:
and generating a convoy path according to the convoy starting point position and the convoy ending point position.
Therefore, the optimal convoy route can be generated by adopting the current navigation related technology based on road congestion conditions, construction conditions and the like according to the convoy starting point position and the convoy ending end point position. Therefore, the passing efficiency of the special vehicle can be further improved.
Optionally, before generating the convoy path according to the convoy application instruction in response to the received convoy application instruction for the special vehicle, the method further includes:
and receiving a convoy application instruction for the special vehicle sent by the user terminal.
Therefore, the user terminal sends the convoy application instruction to the electronic equipment executing the method, so that the user can conveniently operate when driving a special vehicle.
Optionally, based on the foregoing embodiment, after the convoy path is generated, the convoy path may be displayed to the user, so that the user drives the special vehicle to go to the convoy destination location according to the convoy path.
For example, the user is an escort application instruction directly input on the electronic device executing the method, and accordingly, the electronic device can display the escort path through a display module such as a display screen.
Or, no matter the convoy application instruction is sent by the user through the user terminal or directly input, as long as the electronic device executing the method is also connected with the user terminal, the convoy path can also be sent to the user terminal, so that the convoy path can be displayed to the user through the user terminal.
Illustratively, after generating the convoy path according to the convoy application instruction, the method further comprises:
and sending the escort path to the user terminal.
For example, if the user sends an escort application instruction to the electronic device through the user terminal, the electronic device may send the generated escort path to the user terminal for presentation to the user.
For another example, the user provides corresponding parameters (such as a convoy starting point position, a convoy ending point position, an address of a vehicle-mounted device of the special vehicle and the like) to the operator through the handheld radio station, and when a convoy application instruction input by the operator is received, the electronic device executing the method can send a convoy path to the vehicle-mounted device of the special vehicle based on the address of the vehicle-mounted device after the convoy path is generated. Of course, the above is merely an example, and how to send the convoy path to the user terminal is not limited herein.
So, can be convenient for the user to look over the convoy route through user terminal, convenience of customers drives special type vehicle and goes according to the convoy route.
Optionally, before sending the convoy path to the user terminal, as shown in fig. 2, the method may further include:
s201, sending the verification code to the mobile terminal bound to the user terminal so that the user can input the verification code to the user terminal.
S202, receiving the verification code returned by the user terminal.
The mobile terminal bound by the user terminal may be a communication terminal (e.g., a mobile phone) corresponding to a telephone number of a user using the user terminal. Thus, the authentication code can be transmitted to the communication terminal of the corresponding user so that the user can input the authentication code to the user terminal.
Or, the mobile terminal bound by the user terminal may also be a mobile terminal directly bound by the user terminal, that is, the communication address of the mobile terminal bound by the user terminal is stored in the user terminal, so that the user terminal can carry the communication address of the corresponding mobile terminal when sending the escort application instruction to the electronic device executing the method, thereby facilitating the electronic device to send the verification code to the corresponding mobile terminal.
Therefore, the identity of the user can be verified through the verification code input by the user at the user terminal, and the safety of the special vehicle navigation protection function is improved.
Optionally, according to the position information of the special vehicle and the convoy path, controlling, by the signal control system, the annunciator at each intersection on the convoy path to indicate a traffic signal in the traffic direction of the convoy path, and the method may include:
and determining the position of the special vehicle on the convoying path according to the position information, and controlling the annunciators of all intersections on the convoying path to indicate the passing signals in the passing direction of the convoying path through the signal control system according to a preset rule.
Wherein, the preset rule may include:
when the distance between the special vehicle and a first intersection to be passed in front of the passing direction on the escort path is less than or equal to a first preset distance, the signal control system controls a signal machine of the first intersection to indicate a passing signal in the passing direction of the escort path.
When the distance between the first intersection and the second intersection is smaller than the second preset distance, when the signaler of the first intersection is controlled by the signal control system to indicate the traffic signal in the traffic direction of the escort path, the signaler of the second intersection is controlled by the signal control system to indicate the traffic signal in the traffic direction of the escort path.
The second intersection is adjacent to the first intersection and located at the downstream of the first intersection on the convoying path, and the second preset distance is smaller than the first preset distance. For example, the first predetermined distance may be 300 meters, the second predetermined distance may be 200 meters, and so on.
It should be noted that, after the special vehicle drives away from the first intersection, if the distance between the first intersection and the second intersection is greater than the first preset distance, the traffic signal can be indicated in the traffic direction of the convoying path by controlling the annunciator of the second intersection through the signal control system when the distance between the special vehicle and the second intersection is smaller than the first preset distance (that is, the annunciator indicates the green light in the traffic direction of the special vehicle).
And after the special vehicle drives away from the first intersection, if the distance between the first intersection and the second intersection is smaller than the first preset distance but larger than the second preset distance, the signal control system can control the annunciator of the second intersection to indicate a traffic signal in the traffic direction of the escort path after the special vehicle is determined to drive away from the first intersection.
The manner of determining that the special vehicle has driven away from a certain intersection may be that when the distance from the position of the special vehicle to a stop line of the intersection located downstream in the passing direction of the special vehicle is greater than or equal to a threshold (e.g., 30-50 meters), it is determined that the special vehicle has driven away from the corresponding intersection.
By the mode, the position of the special vehicle can be monitored, and when the special vehicle is detected to be about to run to a certain intersection (such as a first intersection) on the convoying path, the signalers of the corresponding intersections are controlled to indicate the traffic signals in the traffic direction of the special vehicle, so that the influence on normal running of the social vehicle is reduced. And when two adjacent intersections (such as a first intersection and a second intersection) are close to each other, the traffic signals of the two intersections can be simultaneously controlled to indicate the traffic signals in the traffic direction of the special vehicle, so that the vehicles queued between the two intersections can pass through more quickly, congestion is reduced, and the traffic efficiency of the special vehicle is improved.
Optionally, in practical application, the preset rule may also be that the annunciators at all intersections on the navigation line are simultaneously controlled to indicate the traffic signal in the traffic direction of the special vehicle, and this time is not limited.
Optionally, after controlling, by the signal control system, the signalers at the intersections on the convoy path to indicate the traffic signals in the traffic direction of the convoy path according to the position information of the special vehicle and the convoy path, as shown in fig. 3, the method may further include:
s301, according to the position information of the special vehicle, determining that the special vehicle drives away from the corresponding intersection on the convoying path.
S302, controlling a signal machine of the corresponding intersection to perform signal indication according to a default signal scheme through a signal control system.
The method for determining that the special vehicle drives away from a certain intersection may be that when the distance from the position of the special vehicle to a stop line of the intersection located at the downstream in the passing direction of the special vehicle is greater than or equal to a threshold (for example, 30 to 50 meters), it is determined that the special vehicle drives away from the corresponding intersection.
The signal indication by the signal machine according to the default signal scheme means that the signal machine restores the existing signal indication scheme and carries out signal indication according to the normal signal indication rule.
Therefore, the condition that the special vehicle passes through the corresponding intersection and is influenced because the signal machine restores to the normal signal indication when the special vehicle does not drive away from the corresponding intersection can be avoided. And moreover, normal signal indication can be recovered in time after the special vehicle drives away from the intersection, and the influence of the special vehicle passing on social vehicles is reduced.
Optionally, based on the above embodiment, a corresponding threshold duration may also be set for each traffic signal, so that when the traffic signal does not receive a corresponding control instruction for performing signal indication according to a default signal scheme, after the threshold duration after receiving the instruction for indicating the traffic signal, the normal signal indication may be automatically restored, thereby avoiding that normal traffic of social vehicles is affected because the normal signal indication is not restored all the time because the traffic signal does not receive the corresponding instruction.
The threshold duration can be determined according to the duration used in the process of starting the control signaler to indicate the passing signal to the special vehicle driving off the intersection. If the set threshold time length is larger than or equal to the time length used for starting the process of controlling the signaler to indicate the traffic signal to the special vehicle to drive out of the intersection.
Illustratively, the distance of the preset special vehicle from the upstream stop line of the intersection in the passing direction of the special vehicle is L Upper part of At the meter, the corresponding annunciator is controlled to indicate a traffic signal, and the distance between the upstream parking space and the downstream parking space at the intersection is L Crossing The distance of the preset special vehicle from the downstream stop line of the intersection in the passing direction of the special vehicle is L Lower part When the vehicle is at the meter, the special vehicle is determined to drive away from the intersection, and the driving speed of the vehicle is V for example. The time length for starting the process of controlling the annunciator to indicate the passing signal to the special vehicle to drive away from the intersection can be calculated according to the following formula:
wherein, T Sheet When the special vehicle applying for convoying is a single vehicle, the time length T used in the process that the traffic signal is indicated to the special vehicle driving off the intersection by the signal controller is controlled Motorcade When the special vehicle applying for convoying is a motorcade, the duration of the process of starting to control the annunciator to indicate the passing signal to the special vehicle to drive away from the intersection is controlled, M is the number of the vehicles in the motorcade, and t is the number of the vehicles in the motorcade Full of food The saturated head interval time of the following vehicles in the motorcade is obtained.
Optionally, when the special vehicle corresponding to the convoy application instruction is a fleet head vehicle and a fleet of special vehicles needs convoy, the special vehicle can delay a certain time threshold value based on the number of the vehicles of the fleet after the head vehicle drives away from the corresponding intersection, and then control the corresponding annunciator to perform signal indication according to a default signal scheme.
Illustratively, the special vehicle is a vehicle fleet head vehicle, and before the signal control system controls the signal machine at the corresponding intersection to perform signal indication according to the default signal scheme, the method may further include:
and determining that the time length of the special vehicle after the special vehicle drives away from the corresponding intersection is not less than a time threshold, wherein the time threshold is determined according to the number of the vehicles in the fleet.
The method for determining the time threshold according to the number of the vehicles in the fleet may be to determine the time of the fleet passing through the intersection according to the number of the vehicles, and then set the time greater than or equal to the time of the fleet passing through the intersection as the time threshold.
The time of the motorcade passing through the intersection can be calculated according to the following formula.
Wherein, T Vehicle fleet The time of the motorcade passing through the intersection is taken as the time; l is a radical of an alcohol Lower part When the special vehicle is determined to drive away from the intersection, the distance between the special vehicle and a downstream stop line of the intersection in the special vehicle passing direction is preset; l is Road junction The distance between the upstream and downstream parking lines at the intersection; m is the number of vehicles in the fleet; t is t Full of The saturated head spacing time of the following vehicles in the motorcade is obtained.
Therefore, the phenomenon that other vehicles of the motorcade recover the default signal indication scheme through the control signal after the head vehicle of the motorcade drives away from the intersection can be avoided, and accordingly the passing of other vehicles of the motorcade is influenced.
Optionally, in this embodiment of the application, when the driving route of the special vehicle deviates from the convoy route, the convoy route may be regenerated according to the current position of the special vehicle, and generally, the foregoing embodiments re-control the signal machines at the intersections on the convoy route to indicate the traffic signals in the traffic direction of the convoy route.
