The uniqueness recognition of the vehicle identity is realized by pre-establishing the vehicle identity of the vehicle, and the inspection is ensured to be the inspection of the corresponding vehicle by the uniqueness recognition of the vehicle identity, so that the influence on the non-inspection vehicle is avoided.
In order to enable the remote inspection process to be the operation which can be performed by an authorized operator, the invention also performs the identity authorization of the operator in advance: the bus company management layer inputs the identity information of one or more drivers corresponding to each bus into the cloud platform in advance, and the Internet of vehicles cloud platform corresponds the identities of the drivers and the identities of the vehicles, so that the authorization of the identities of the drivers is realized. Through storing personnel's identity in advance to with personnel's identity and vehicle identity phase-match, realized operating personnel's identity authorization process, operating personnel can carry out the remote operation of patrolling and examining to appointed vehicle promptly, and operating personnel does not have the vehicle of authority operation to self, can not carry out the remote operation of patrolling and examining, so to operating personnel's vehicle authorization process, guaranteed the security that the vehicle was patrolled and examined remotely.
The implementation process of the vehicle remote inspection specifically comprises the following steps:
as shown in fig. 2, the remote inspection of the vehicle specifically comprises the following steps:
1) firstly, judging whether the vehicle meets the starting remote inspection condition, namely judging that the power supply of the ON gear of the whole vehicle is effective, the vehicle speed is zero and the vehicle is in the P gear; and if the remote inspection starting condition is met, performing the step 2), otherwise, ending the remote inspection process of the vehicle. In the process, when the authorized objects such as a driver or a security inspector do not need to remotely patrol, safety accidents caused by system misoperation caused by communication faults or hacking and the like are considered, so that the working and non-working conditions of the remote patrol function are set, namely, the remote patrol condition is started: the power supply of the whole vehicle ON gear is effective, the vehicle speed is zero, and the vehicle is positioned in P gear; the forbidden remote polling condition is as follows: vehicle speed > zero or vehicle in R, N, D any gear. This process is whether to judge the vehicle in advance and to satisfy the condition of patrolling and examining to just open the operation of patrolling and examining when satisfying, can effectively avoid when the vehicle does not satisfy the condition of patrolling and examining, the system maloperation that communication fault or hacker invasion etc. caused leads to the vehicle safety to receive the condition of threatening, so judge before patrolling and examining whether the vehicle satisfies the process of opening the long-range condition of patrolling and examining, promoted the safety of vehicle. As another embodiment, the next step may be started without performing this process.
2) The operating personnel patrols and examines the button through clicking a certain, if light patrols and examines (can be according to different public transit company management demands, it can be one or more to patrol and examine the button), opens this function of patrolling and examining.
3) After the patrol inspection function is started, the mobile phone APP transmits the recognized patrol inspection starting signal to the cloud server through the Internet of vehicles.
4) After receiving the starting signal, the cloud server converts the starting signal into a corresponding instruction according to a communication protocol agreed by the cloud and the vehicle end, such as an instruction for starting the light inspection, and transmits the instruction to the vehicle-mounted terminal through the internet of vehicles.
5) After receiving the instruction transmitted by the cloud server, the vehicle-mounted terminal equipment judges whether the remote inspection condition is forbidden or not, if the remote inspection condition is not forbidden (namely the remote inspection condition is met), the vehicle-mounted terminal equipment converts the instruction into a CAN message format and sends the CAN message format to a vehicle-side gateway; if the remote patrol condition is forbidden (namely the remote patrol condition is not met), the vehicle-mounted terminal does not convert the patrol instruction. As another embodiment, whether the remote inspection condition is forbidden or not is judged, and after the gateway receives the CAN message, if the remote inspection condition is forbidden, the gateway does not forward the CAN message to the network where the controller is located; or judging whether the remote inspection condition is forbidden, or after the network where the corresponding controller is located receives the CAN message forwarded by the gateway, if the remote inspection condition is forbidden, the corresponding controller does not execute the corresponding function.
6) And the vehicle-end gateway analyzes the CAN messages, identifies the target address, and sends the target address to one or more CAN networks where the controller is located according to the target address.
7) And after the controller of the corresponding component receives the enabling signal, the corresponding component is driven to work according to the polling mode. The inspection mode defaults to a working duration (e.g., 2 minutes, which may be set, and the default working durations for inspecting different components may vary, which may be based on an average working time for an operator to inspect the corresponding component as the default working duration). At this time, the operator starts to check the state of the corresponding component (for example, light) of the vehicle around the vehicle.
8) After the state of the operator is checked, if the inspection mode reaches the default working time, the inspection mode is automatically exited; if the time does not reach, at the moment, the operator can also manually close the inspection mode on the mobile phone APP. Quit the mode of patrolling and examining through the set time for operating personnel need not to click the shutdown button, just can realize surpassing the function that the mode of patrolling and examining was withdrawed from in the set time automatically, and then reduced operating personnel and closed the step of patrolling and examining the mode, and this automatic setting of quitting has avoided leading to patrolling and examining the mode and not closing in time because of operating personnel's carelessness, cause the extravagant condition of vehicle energy, and operating personnel is after patrolling and examining, but not reach acquiescent operating duration, send down through communications facilities and patrol and examine the shutdown signal, just can realize quitting the mode of patrolling and examining, make when operating personnel is efficient, realize withdrawing from the mode of patrolling and examining through sending down the shutdown signal of patrolling and examining, equipment still is in service after avoiding the work, cause the extravagant condition of vehicle energy. As other embodiments, the timeout time setting may not be performed, or other methods for turning off the patrol mode may be set.
The invention realizes the daily inspection function of the functional components of the whole vehicle in a remote control mode by utilizing the vehicle networking technology and the CAN bus technology, and replaces the original scheme of manually operating and inspecting one by one. The number of participating in for accomplishing to patrol and examine has been reduced, makes originally need two people complex work become can simply accomplish alone, helps the execution of falling to the ground of public transit company safety control regulation, promotes vehicle operation security.
Based on the above process, the present invention also considers that there are two modes of operation in step 1): 1. and (3) a polling mode: on the premise of meeting the remote polling starting condition, the mobile phone APP polling function is in a related working mode in a starting state; 2. a non-inspection mode: under the condition that the function is not opened in cell-phone APP patrols and examines, according to driver's wish, through the relevant mode that carries on when approaches such as driver's operation or vehicle sensor reach operating condition. And when the two working modes are simultaneously met (namely the power supply of the whole vehicle ON gear is effective, the vehicle speed is zero, the vehicle is positioned in the P gear and the vehicle is in manual operation), the priority of the non-inspection mode is higher than that of the inspection mode, namely the priority is given according to the real intention of the driver. The method comprises the following steps that when the remote inspection condition is met and the operation condition of an operator is met, the operation is preferentially carried out according to the operation of the operator, namely when the remote inspection condition is met, the operator can carry out related working modes when the working condition is met through the operation of the operator or the operation of a vehicle sensor and the like according to will, at the moment, the remote inspection mode is not entered, and the related working modes are preferentially carried out. By setting the priority, the problem of vehicle safety caused by operation conflict is avoided when two conditions are met simultaneously and the vehicle executes the operation under the two conditions simultaneously, and the condition that the operation process of the vehicle is interrupted by the operator due to the fact that the operation of the operator is set to be higher than that of remote inspection by setting the priority of the operation of the operator is avoided. This process ensures vehicle safety and continuity of vehicle operation.
On the basis of the scheme, the practical field inspection has the following operation steps:
1) an operator turns on a mechanical manual power main switch near a vehicle storage battery;
2) an operator opens a vehicle door, and turns an ignition key to an ON gear in a driving area after getting ON the vehicle;
3) an operator turns on a mobile phone remote control APP, clicks a corresponding inspection switch in the APP, and then, corresponding parts start to work according to a preset inspection mode;
4) whether the response component works normally or not is inspected by an operator outside the vehicle;
5) if all the devices to be checked are normal after the inspection, the inspection mode can be ended in two modes: 1. the operator clicks the polling switch again and directly ends the polling mode; 2. and automatically releasing the mode after the working time of the inspection mode exceeds the default time. If the component is found to be damaged during inspection, the component should be repaired or prepared according to the specific regulations of the company.
Through the long-range process of patrolling and examining of vehicle, reduced the use of manpower, improved the efficiency of patrolling and examining to through the concrete process of the aforesaid, guaranteed that the long-range process of patrolling and examining of vehicle is patrolled and examined the safety of patrolling and examining the vehicle, help the execution of falling to the ground of public transit company safety control regulation, promote vehicle operation security.
