Generally, in order to ensure that the CPC card can communicate with the corresponding portal unit when passing through each portal unit, the CPC card is required to always open the communication assembly, and the communication assembly also consumes electric quantity when a vehicle runs and does not reach the portal unit, so that the service time of a battery in the CPC card is shortened. According to the scheme, when a vehicle passes through a portal unit, a CPC card can predict the time of the vehicle reaching the next portal unit, and when the vehicle leaves the current portal unit, a communication component of the CPC card enters the dormancy state and is awakened at the predicted time so as to be convenient for communication with the next portal unit; when the vehicle runs and does not communicate with the portal unit, the communication component of the CPC card is in a dormant state, so that the electric quantity consumption caused by continuous work of the communication component of the CPC card in estimated time is reduced, the electric energy of a battery in the CPC is saved, the endurance time of the CPC card is prolonged, and the detailed embodiment is as follows:
the embodiment of the application provides a control method of a composite express card on a highway, which is executed by a CPC card, as shown in fig. 1, the method includes:
and S101, communicating with the portal unit in the current communication range to acquire the traffic information of the current road section.
The traffic information of the current road section comprises the highest speed limit information of the current road section and the distance information between the portal unit in the current communication range and the next portal unit in the vehicle driving direction.
For the embodiment of the application, the passing information can be stored in the portal unit in advance, and when the CPC card is communicated with the portal unit, the passing information stored in the portal unit is obtained; or when the CPC card communicates with the portal unit, the portal unit downloads the traffic information in real time through the network, so that the CPC card acquires the traffic information downloaded by the portal unit in real time.
And S102, determining estimated time based on the acquired traffic information of the current road section.
The estimated time is the estimated time from the driving of the current vehicle from the portal unit in the current communicable range to the next portal unit in the driving direction of the vehicle.
For the embodiment of the application, when the vehicle runs on the expressway, the condition that the vehicle stops midway is not considered, if the vehicle runs at the constant speed of the highest speed limit on the highway section, the actual time of the vehicle from the portal unit in the current communicable range to the next portal unit in the running direction is equal to the estimated time; when the speed of the vehicle is changed in the driving process and does not exceed the highest speed limit of the high road section all the time, the actual time of the vehicle from the door frame unit in the current communication range to the next door frame unit is necessarily greater than or equal to the estimated time, namely the estimated time is the shortest time which can be used under the condition that the vehicle does not overspeed in the driving process.
And S103, when the communication with the portal unit in the current communication range is finished, controlling the communication assembly to sleep, and awakening the communication assembly based on the estimated time.
For the embodiment of the application, when the communication assembly is awakened at the dormancy prediction time, the vehicle should not reach the next portal unit or just reach the next portal unit, so that the CPC card can communicate with the next portal unit through the communication assembly.
For the embodiment of the application, the estimated time when the vehicle reaches the next portal unit from the current portal unit is obtained through the highest speed limit information of the current road section and the distance information between the portal unit in the current communicable range and the next portal unit in the vehicle driving direction. In the estimated time, the communication module of the CPC card does not communicate with the door frame unit, so that the estimated time of the communication module of the CPC card is controlled to be dormant, and the electric quantity of the battery in the CPC card can be saved.
Further, step S102 may specifically include: step S1021 (not shown in the figure) and step S1022 (not shown in the figure),
step S1021, acquiring the current speed information of the vehicle;
specifically, the acquiring of the current speed information of the vehicle may specifically include: the vehicle is tested the speed through the tachymeter that predetermines on the portal unit, then the speed information of vehicle is acquireed by the CPC card when portal unit and CPC card can carry out the communication. The manner of acquiring the current vehicle speed information may further include: the CPC card is internally pre-installed with speed measuring software, so that the current measuring speed can be measured in real time.
Step S1022, judging whether the current vehicle is overspeed or not based on the current speed information of the vehicle and the highest speed limit information of the current road section; if the speed exceeds the speed limit, the estimated time is determined to be the first preset time.
Specifically, the first preset time may be 2S, 8S, and 10S, and the specific time of the first preset time is not limited in any way in the embodiment of the present application as long as the first preset time is less than or equal to the actual shortest time for the vehicle to reach the next portal unit from the portal unit in the current communicable range.
Specifically, the actual minimum time taken for the vehicle to reach the next mast unit from the mast unit within the currently communicable range may be obtained based on the theoretical maximum travel speed of the motor vehicle and the minimum distance between the mast unit within the currently communicable range and the next mast unit.
Specifically, when the vehicle runs on the expressway at an overspeed, the time that the vehicle runs at the highest speed limit exceeding the current road section cannot be judged, so that the minimum estimated time for the vehicle to arrive at the next portal unit cannot be estimated more accurately. Therefore, when the vehicle passes through the portal unit, if the current vehicle is overspeed, the estimated time is set to be first preset time, so that the vehicle can communicate with the portal unit when passing through the next portal unit, and certain electric quantity of the CPC card can be saved.
Further, if there is a bifurcation intersection between the portal unit in the current communicable range and the next portal unit in the vehicle driving direction in the road segment, step S102 may specifically include: step S1023 (not shown), step S1024 (not shown), and step S1025 (not shown), wherein,
and S1O23, if the road section has a bifurcation intersection between the portal unit in the current communicable range and the next portal unit in the vehicle driving direction, determining at least two pieces of distance information based on the acquired traffic information of the current road section.
And the distance information is respectively the distance information between the mast unit in the current communication range and the next mast unit on each branch road in the vehicle driving direction.
Step S1024, determining minimum distance information from at least two pieces of distance information.
Specifically, when a bifurcation exists in the driving direction of the vehicle, the CPC card cannot obtain the destination information of the vehicle owner, so that the next portal unit to be reached by the vehicle cannot be known; it is therefore necessary to obtain the distance from the mast unit currently within the communicable range to the next mast unit at each branch point in the traveling direction and then select the minimum distance among the plurality of distances.
For example, if there are two branched intersections, namely, branched intersection 1 and branched intersection 2, in the road section between the portal unit in the current communicable range and the next portal unit in the vehicle driving direction, where the distance between the portal unit in the current communicable range and the portal unit corresponding to branched intersection 1 is 2400 m, and the distance between the portal unit in the current communicable range and the portal unit corresponding to branched intersection 2 is 2600 m, the distance between the portal unit in the current communicable range and the portal unit corresponding to branched intersection 1 is determined as the minimum distance information.
And step S1025, determining the minimum estimated time based on the highest speed limit information and the minimum distance information of the current road section.
For the embodiment of the application, after the minimum distance information is determined through the above steps, based on the minimum distance information and the highest speed limit information of the current road section, the minimum estimated time may be obtained, for example, if the highest speed limit of the current road section is 120 KM/h, the minimum distance information is 2400 meters, and the minimum estimated time is 72 s.
After obtaining the minimum estimated time, waking up the communication component based on the estimated time, which may specifically include: based on the minimum estimated time, the communication component is awakened.
Specifically, the minimum estimated time of the next closest portal unit in the driving direction of the vehicle is determined according to the minimum distance and the highest speed limit information of the road section, and the minimum time is used as the estimated time of dormancy of the CPC card communication component; that is, when the communication component is awakened, the vehicle does not arrive at or just arrives at one portal unit on the branch road, and the probability that the CPC card cannot communicate with the portal unit because the communication component of the CPC card is not awakened when the vehicle arrives at the next portal unit is reduced.
Further, it should be determined whether there is a bifurcation intersection between the mast unit within the front communicable range and the next mast unit in the vehicle traveling direction before performing step S1023.
Specifically, the manner of determining whether there is a bifurcation intersection between the mast unit currently within the communicable range and the next mast unit in the traveling direction of the vehicle includes at least one of scheme 1 and scheme 2, wherein,
scheme 1: and determining the current position information of the vehicle, and determining whether a branched intersection exists between the portal unit in the current communicable range and the next portal unit in the vehicle driving direction based on the current position information of the vehicle and the map information.
Specifically, the position information of the vehicle may be determined by a Global Positioning System (GPS) or a beidou Positioning module preset in the CPC card, or the position information stored in the portal unit may be acquired when the CPC card communicates with the portal unit in the current communicable range. Meanwhile, when the CPC card is communicated with the portal unit in the current communication range, the expressway map information stored in the portal unit or the expressway map information downloaded is acquired; and judging whether a bifurcation intersection exists in the current driving direction or not according to the current position information of the vehicle.
Scheme 2: and acquiring indication information from the portal unit in the current communication range, and determining whether a bifurcation intersection exists between the portal unit in the current communication range and the next portal unit in the vehicle driving direction based on the indication information.
Specifically, if a bifurcation intersection exists behind the portal unit, indicating information is stored in advance, the indicating information is used for determining that the bifurcation intersection exists on a road behind the portal unit, and meanwhile, the portal unit stores distance information between the portal unit and portal units on next bifurcation intersections; and if no bifurcation intersection exists, only storing the distance information between the gantry unit and the next gantry unit.
Further, based on the estimated time, waking up the communication component may specifically further include: and when the awakening signal of the gantry unit is received and the estimated time is not reached, awakening the communication assembly. In this application embodiment, the portal unit can also send wake-up signal to awaken the communication subassembly in the CPC card, in order to make the CPC card can in time communicate with the portal unit, when the module of awakening of portal unit is received, when not reaching the estimation time this moment, also awaken up the communication subassembly in the CPC card.
