Description
Technical Field
[0001] The utility model relates to the technical field of task execution of shared electric vehicles, and in particular to an asynchronous task execution module based on a message queue. Background Art
[0002] The task execution module is a software module used to track, organize and execute tasks. It can help users manage task lists, set task priorities, assign tasks to specific people, and monitor the progress of tasks. Existing shared electric vehicles are generally equipped with task execution modules. Users enter the program by scanning the code, and then place an order and start the vehicle from within the program. The usage process is relatively convenient, providing great convenience to users.
[0003] However, when the existing shared electric vehicles are in use, the execution module cannot perform asynchronous task execution and cannot review and identify orders placed by multiple groups of customers. If two people scan the code at a similar time, the person who scans the code first will enter the program more slowly due to poor signal, which will give the user an unfair feeling. At the same time, the existing task execution components are not easy to install and disassemble, so an asynchronous task execution module based on a message queue is needed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to solve the problem that when the existing shared electric vehicles are in use, the execution module cannot perform asynchronous tasks and cannot review and identify orders placed by multiple groups of customers. If two people scan the code at a similar time, the person who scans the code first will enter the program more slowly due to poor signal, which will give the user an unfair feeling. At the same time, the existing task execution components are not easy to install and disassemble. Therefore, an asynchronous task execution module based on a message queue is proposed.

[0006] Preferably, a telescopic arc piece is slidably connected inside the hoop, a limiting sliding opening is provided on one side of the hoop, and a handle is connected to the limiting sliding opening.

[0012] Beneficial Effects
[0013] In the utility model, the execution module in the device is wearable and can be put on the shared electric vehicle. When the user needs to scan the car, he directly scans the QR code in the top scanner, and then he can proceed to the next step. During installation, first put the hoop on the appropriate position of the car body, and then pull the handle to slide the telescopic arc piece down to adjust the size of the restraint. It should be noted that the handle is foldable. After the execution module is put on, the telescopic arc piece is pulled down by the handle so that the plug at the bottom of the telescopic arc piece is directly inserted into the socket at the bottom of the hoop, and then a special bolt is selected to penetrate the opening and the matching hole at the same time to fix it. The special bolt here can only be tightened and loosened by a special screwdriver, which can play an anti-theft role to a certain extent.
[0014] In the utility model, the control terminal is a small computer. The control terminal can obtain the information of multiple users at the same time, and determine which user to grant the right of use according to the user's location information, scanning time and payment time, so as to prevent unnecessary competition among users. After obtaining the user information, the control terminal will store the information of each scanned user separately through the grouping storage module, and then transmit it to the nearest Bluetooth transmission base station through the transmission module Bluetooth, and then transmit it to the order processor.
[0015] In the utility model, after multiple groups of user information are transmitted to the order processor, they will be directly fed back to the message queue execution module. The message queue execution module will asynchronously process the orders of multiple groups of users. The comparison and identification end is the execution end of the message queue execution module with a built-in merchant-specific system, which will compare the multiple groups of user information. The comparison will be done through the merchant's special system. The main comparison is the distance from the vehicle, the order of scanning time and the order of payment time. When the location of a user is close, the scanning time and the payment time are advanced, it will be determined that the customer can use the vehicle, and then the comparison result will be transmitted to the feedback transmitter. The feedback transmitter here transmits a start signal instruction, which will directly remotely control the power system of the vehicle used by the customer, and control it to unlock, and then the user can use it.
