fig. 1 is a schematic flowchart of a remote instruction issuing method for batch vehicle-mounted devices according to an embodiment of the present invention.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.
The invention provides an embodiment of a remote instruction issuing method for batch vehicle-mounted equipment, and specifically, as shown in fig. 1, the method includes:
step S1, before issuing an instruction, an instruction server determines the online state of each vehicle-mounted device through an equipment gateway;
firstly, before an instruction server issues an instruction to a vehicle-mounted T-box, the online state of a target device (namely, a vehicle-mounted device needing to issue the instruction) can be inquired through an equipment gateway, in actual operation, tcp heartbeat data can be sent to the equipment gateway by the vehicle-mounted device according to a set period, the online state of the vehicle-mounted device is recorded by the equipment gateway based on the tcp heartbeat data, and based on the tcp heartbeat data, if the tcp heartbeat data of the vehicle-mounted device is not received after a preset time length is exceeded, the online state of the vehicle-mounted device is removed by the equipment gateway.
S2, dividing the on-line vehicle-mounted equipment into a plurality of groups based on the bearing capacity of the instruction issued by the equipment gateway;
specifically, the number of the vehicle-mounted devices in each group is predetermined by the bearer amount of the command issued by the device gateway, for example, one thousand may be taken as the number of the vehicle-mounted devices in each group.
S3, taking the group as a unit, and issuing an instruction to the vehicle-mounted equipment in the single group by the instruction server through the equipment gateway;
s4, after the instruction is sent to the current group, waiting and recording the instruction response of the vehicle-mounted equipment in the current group;
and S5, triggering to issue the instructions to each vehicle-mounted device in the next group based on the instruction response of the current group, and repeating the steps until the instructions in all the groups are sent.
With respect to the above concept, the following specific description can be made:
that is, the device gateway issues instructions to all the vehicle-mounted devices in the first group (for example, the group number is group 1, which may not be limited) at the same time in a multithreading manner. And after the command is sent, waiting for a command response of the vehicle-mounted equipment in the current group, and further, correspondingly inputting the received command response into a preset equipment command mapping table by the command server, wherein the equipment command mapping table is used for recording reply information of the vehicle-mounted equipment after receiving the remote command, and accordingly, judging whether the vehicle-mounted equipment receives the issued remote command. In actual operation, the device instruction mapping table is stored in a memory of the instruction server in a list form of key value pairs, and the key value pairs are formed by the vehicle-mounted device and the instruction response.
In the foregoing, the instruction response based on the current group triggers instruction issue for each vehicle-mounted device in the next group, and may be considered from two aspects of instruction issue success rate and/or device gateway load: for example, when the number of received command responses is greater than or equal to a predetermined proportion (e.g., two thirds) of the number of the vehicle-mounted devices in the current group, it indicates that most of the remote commands in the group have been successfully received by the vehicle-mounted devices; or, when the current time is greater than or equal to a predetermined multiple (e.g., 1.5 times) of the preset instruction response average time length, it indicates that the load of the device gateway at the current time is low, and in order to ensure that the instruction of the next packet is sent, when at least one of the two aspects is satisfied, the remote instruction issuing may be triggered to be performed on the vehicle-mounted device in the next packet (e.g., the aforementioned packet number, packet 2).
Finally, it may be added to the foregoing step S1 that, if the command server determines that the vehicle-mounted device is not online through the device gateway, the off-line vehicle-mounted device may be placed in a preset offline device pool. Based on the concept, the instruction server may also preferably query whether the online state of the vehicle-mounted device in the offline device pool changes at regular time, if the online state of the vehicle-mounted device in the offline device pool changes to online, take the vehicle-mounted device currently in the online state out of the offline device pool, and perform grouping and instruction issuing processing according to a grouping strategy; and if the vehicle-mounted equipment is still in the offline state, continuously keeping the vehicle-mounted equipment in the offline equipment pool.
In summary, in order to solve the problem that the batch instruction issuing fails due to the existing round training mechanism, the online states of the vehicle-mounted devices may be determined by the device gateway before the instruction server issues the instruction, the online vehicle-mounted devices may be grouped based on the carrying capacity of the device gateway, then the vehicle-mounted devices in a single group may be issued with the instruction in a group unit, the instruction response of the vehicle-mounted devices in the current group is waited for and recorded, the instruction issuing of the vehicle-mounted devices in the next group is triggered based on the instruction response of the current group, and so on until the instructions in all the groups are sent completely. The invention can greatly reduce the burden of the equipment gateway and effectively utilize the resources of the server, thereby providing sufficient guarantee for the reliability of issuing the batch instructions.
