s11, receiving a driver login request from a driver vehicle-mounted terminal; for the driver, the driver vehicle-mounted terminal is used normally, so the driver vehicle-mounted terminal is selected to be used for logging in general.
S12, judging whether the driver has a task according to the driver ID, and if so, issuing the task to the driver vehicle-mounted terminal of the driver; in the embodiment, it is preferable that the driver ID and the vehicle ID are used together to determine whether the driver has a task; and the driver ID is bound with the vehicle ID, so that the purpose that a special person specializes in the vehicle is achieved.

Therefore, the driver ID is registered in the corresponding driver vehicle-mounted terminal, and the driver can be associated with the vehicle.
S13 judging whether the working state of the driver vehicle-mounted terminal is normal by receiving the heartbeat packet from the driver vehicle-mounted terminal, if not, logging again, specifically, if the heartbeat packet from the driver vehicle-mounted terminal is not received after the set time I is exceeded, the working state of the driver vehicle-mounted terminal is considered to be abnormal (namely, abnormal transmission) and timing is started from the last heartbeat packet received from the driver vehicle-mounted terminal, and if the driver login request initiated from the driver mobile terminal by the driver is received within the set time II, the task of the driver is recovered to the driver mobile terminal; if a driver login request initiated by the driver from the driver vehicle-mounted terminal is received within the set time II, the task of the driver is recovered to the driver vehicle-mounted terminal; and if the driver login request from the driver is not received within the set time II, the vehicle where the driver vehicle-mounted terminal is located is offline.
In addition, when the recovery task is sent to the driver mobile terminal or the driver vehicle-mounted terminal, the current position of the vehicle is obtained, and the latest state task is sent to the driver mobile terminal or the driver vehicle-mounted terminal.
The interval sending interval time of the heartbeat packets is preset, for example, 3 seconds and 1 time, when the task issuing supervision and management end exceeds the set time I, if the heartbeat packet from the driver vehicle-mounted terminal is not received in 6 seconds, the abnormality of the driver vehicle-mounted terminal is judged, and timing is started after the last heartbeat packet from the driver vehicle-mounted terminal is received. Of course, in practice, what problem task is specifically generated by the vehicle-mounted terminal of the driver, and the task issuing and monitoring management terminal cannot know the problem task and can only make preparation by several hands:
if the driver vehicle-mounted terminal is only temporarily abnormal and logs in again within the set time II, for example, 5 minutes, the task of the driver is recovered to the driver vehicle-mounted terminal.
If the driver vehicle-mounted terminal has a short-term unrepairable fault, the driver vehicle-mounted mobile terminal initiates login within the set time II, and the task of the driver is recovered to the driver mobile terminal.

If the driver mobile terminal resumes logging on within a set time III, e.g. 5 minutes, the driver's task is resumed to the driver mobile terminal. Of course, it is also possible to restore the driver's task to the driver's in-vehicle terminal if the driver's in-vehicle terminal is restored to the login within the set time III. And if the login from the driver is not received within the set time III, forcibly taking the vehicle bound by the mobile terminal of the driver off the line.

And S25, if the working state of the driver mobile terminal is abnormal (namely abnormal), restarting the driver mobile terminal, then initiating the login request to the task issuing supervision terminal again, and requesting the task issuing supervision terminal to recover the task after the login is successful. Similarly, for the driver, it is preferred that the driver mobile terminal is restarted and then the login is immediately resumed when the driver mobile terminal is abnormal.
Preferably, a specific process of the method for issuing, supervising and managing the driving task and acquiring the driving task is shown in fig. 6, wherein a large data platform of the train (namely, a cloud platform, namely, a task issuing, supervising and managing end) interacts with information of a passenger reservation system (namely, a passenger reservation module), a scheduling system (namely, a scheduling module), a vehicle-mounted terminal system and an operation system to realize processing and application of data.

Lcolumn(s) of＝(N-1)Th*V2+L (1)

It can be understood that the value of x may be preset by a worker, or may be customized by a task issuing supervision and management terminal (or a driver mobile terminal, a driver vehicle-mounted terminal) based on actual road conditions, for example, when there are many vehicles on the road, the value of x is set to be smaller, for example, 0.7, 0.75, etc., so as to increase the green wave guiding vehicle speed, that is, the driving speed of the train vehicle.
Of course, in other embodiments, when there are fewer vehicles on the road, for example, only a single vehicle is passing, the green wave guided vehicle speed calculation module may also calculate the green wave guided vehicle speed by counting the distance of the stop line of the intersection and the red light count down according to the current position of the vehicle, as follows:

the second green wave vehicle speed guiding module is configured to acquire a green wave timing scheme on a driving route from the task issuing monitoring management end by using the long connection established by the long connection establishing module and the task issuing monitoring management end, calculate and acquire green wave bandwidth information based on the green wave timing scheme, and calculate and acquire a green wave guiding vehicle speed according to the green wave bandwidth information, the length of the train where the vehicle is located (i.e., the length of the intelligent train), and the current position of the vehicle, or acquire the green wave bandwidth information according to the task issuing monitoring management end, and calculate and acquire the green wave guiding vehicle speed according to the green wave bandwidth information, the length of the train where the vehicle is located, and the current position of the vehicle (specifically, the method for calculating the green wave bandwidth information, the length of the train, and the green wave guiding vehicle speed refers to the method for calculating the task issuing management end).
Wherein the green wave timing scheme information includes: cycle duration, phase sequence, split, phase difference, etc. The green band width information includes: the maximum green bandwidth.
In some embodiments, the green wave bandwidth information further includes a traffic light signal duration for each signal control intersection within the corresponding green light zone region (based on which a red light countdown or a green light countdown for a next intersection in the vehicle travel direction may be obtained).
In some embodiments, the maximum width of the green light traffic lane width (i.e., green lane width) for vehicles to continuously pass through each intersection is the maximum green lane width according to a specified vehicle speed (e.g., green-wave guided vehicle speed) in the green lane region, where the green lane width is the transit time of all vehicles in the train passing through the intersection. In a specific embodiment, the widths of the green light passing bands of three consecutive intersections are calculated as follows: since the vehicle speed is designed by setting b1 to 35s, b2 to 30s, b3 to 33s and setting b2 to 30s as the width of the green bandwidth, the train can smoothly pass through the green lights at three intersections, and therefore, b to 30s is the maximum width of the green light passing band continuously passing through each intersection, that is, the maximum width of the green bandwidth.
Further, the driver mobile terminal further includes:
and the fourth green wave vehicle speed guiding module is used for comparing the magnitude relation between the current vehicle speed of the vehicle and the green wave guiding vehicle speed in real time, sending a first signal (for example, carrying out voice and text reminding through a driver mobile terminal) for representing deceleration when the current vehicle speed is compared to be greater than the maximum green wave guiding vehicle speed, and sending a second signal for representing acceleration when the current vehicle speed is compared to be less than the minimum green wave guiding vehicle speed.
Further, the driver mobile terminal further includes:
and the green wave timing scheme acquisition module is used for acquiring the green wave timing scheme through the task issuing supervision and management end.
Specifically, in some embodiments, the second green wave guided vehicle speed module accurately locates an optimal time position of each vehicle in the green wave bandwidth of the train based on the green wave bandwidth information and in combination with information such as the length of the intelligent train and the current position of the vehicle, and performs real-time calculation of the green wave guided vehicle speed of the train according to the time, and finally performs display and guidance on the driver terminal.
Preferably, the display and guidance of the green wave guided vehicle speed is as shown in fig. 4, and the green wave bandwidth is presented on the electronic map in the form of a scroll bar, including a scroll bar 1 representing the full length, a slider representing the green wave bandwidth, and an icon 2 representing the vehicle. Both the slider and the icon 2 can be moved along the scroll bar 1. The two ends of the slider are low probability regions 4 and the middle is a high probability region 3. The icon 2 is located in the high probability area 3 to indicate that the road junction arrived later can meet the green light, or the passing probability is high, and if the icon 2 is located in the low probability areas 4 at the two ends to indicate that the probability of meeting the green light is low, the next road junction can meet the green light by accelerating or decelerating. For example, when the icon 2 is located in the lower low probability region 4 (corresponding to the second signal indicating acceleration from the driver's in-vehicle terminal or mobile terminal), acceleration is required to ensure that the intersection is just a green light when arriving, and when the icon is located in the upper low probability region 4 (corresponding to the first signal indicating deceleration from the driver's in-vehicle terminal or mobile terminal), deceleration is required.
Further, for more clearly guiding the vehicle speed, when the icon 2 is located at the center of the high probability region 3, it indicates that the vehicle has the highest probability of encountering a green light at the next intersection, and when the icon 2 gradually moves towards the two ends of the high probability region, the probability of encountering a green light at the next intersection is gradually reduced, so that when the driver observes that the icon 2 moves towards the two ends of the high probability region 3, the vehicle speed can be adaptively controlled so that the icon 2 is as close as possible to the center of the high probability region 3, and the icon 2 is prevented from falling into the low probability region 4, and of course, it can be understood that when the icon 2 is located at the middle position or the two ends of the high probability region, the probability of encountering a green light at the next intersection is in a higher range.
The information of the green wave timing scheme can be acquired from a traffic management bureau, the green wave timing information is uploaded to a task issuing supervision management terminal, and the task issuing supervision management terminal issues the green wave timing information in the form of a task packet (a driver vehicle-mounted terminal) or long-connection communication (a driver mobile terminal) after calculation processing.
In fact, the driver mobile terminal can be a mobile phone and an APP installed in the mobile phone, so that the functions are realized. And the functions such as task query, platform calling, login mode setting and the like can be realized.
Specifically, in some embodiments, the green wave timing scheme information is obtained through a traffic signal controller and a traffic signal system of a traffic control department, so as to calculate and extract green wave bandwidth information, and information such as train length of an intelligent train and current position of a vehicle is combined to accurately locate the optimal time position of each vehicle in the train in the green wave bandwidth, and the train green wave guiding vehicle speed (i.e., target vehicle speed) is calculated in real time based on the time, and then display guidance is performed through a driver terminal (as shown in fig. 4).
Specifically, referring to fig. 5, the acquisition of the green wave timing scheme information includes two paths, where the first path is as shown in fig. 5 (a), the green wave timing scheme information is acquired by butt joint of a Road Side Unit (RSU) and a signal machine of a traffic control department, and then the road side unit uploads the information to a cloud platform (i.e., a running task issuing supervision and management end), and the cloud platform broadcasts the information to corresponding vehicles after calculation processing; in the second path, as shown in fig. 5 (b), the cloud platform and the traffic signal control system of the traffic control department are docked to obtain the related information of the green wave timing scheme, and the green wave timing scheme information is obtained based on the related information, and then is broadcasted to each corresponding vehicle.
Preferably, in some embodiments, the cloud platform is selected to calculate the green wave bandwidth based on the green wave timing scheme information, and of course, the green wave bandwidth may also be calculated by the intelligent vehicle-mounted terminal or the RSU.
Preferably, in some embodiments, information with high requirements for accuracy and real-time performance (e.g., real-time information such as GPS and green wave) is transmitted by using a long connection, so that information loss is avoided; of course, information with relatively low requirements for accuracy and real-time performance (for example, operations such as switching of the mobile terminal) can also be transmitted by using a short connection, so that the data transmission amount can be reduced, and the operation efficiency of the mobile terminal (i.e., APP) can be improved.
As shown in fig. 3, the present invention further provides a driving task service system, which includes the driving task issuing and monitoring management terminal and the driving task obtaining terminal.
The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and these modifications and adaptations should be considered within the scope of the invention.
