201: and receiving the state information periodically reported by the front-end electronic police equipment.
In an embodiment, each front-end electronic police device may report status information periodically according to the same or different periods, where the status information includes a device identifier of the front-end electronic police device and a corresponding reporting time.
In one embodiment, after receiving the state information, the receiving server stores the state information for later-period call verification, for example, the receiving server writes the state information into the storage server for persistent storage for the operation and maintenance staff to inspect and eliminate, and simultaneously sends a piece of data to the state server to be stored in a cache for being used as verification evidence when the illegal warehousing server performs blocking processing, the cache data sets a certain validity period, and the data exceeding the validity period is automatically cleaned.
In one embodiment, prior to this step, the method of fig. 2 further comprises: the method comprises the steps that a data management platform and front-end electronic police equipment are initialized, the front-end electronic police equipment is registered in a receiving server and an illegal warehousing server in the data management platform, and the receiving server sends a reporting trigger instruction to the front-end electronic police equipment; and the reporting triggering instruction is used for triggering the front-end electronic police equipment to randomly determine the initial reporting time of the state information.
In an embodiment, the trigger instruction carries a random function y ═ rand (x), the front-end electronic police device receives the trigger instruction at a time t0, and then the front-end electronic police device inputs a unique device identifier of the front-end electronic police device, such as a MAC address, as x into the random function y ═ rand (x) to obtain a random number y as an initial reporting time, for example, the random number determined by the front-end electronic police device is 60, and then the time t1 is used as the initial reporting time, where t1 ═ t0+60 seconds, and when the time t1 arrives based on the local time of the front-end electronic police device, the first transmission of the state information is performed, and the state information carries the device identifier of the front-end electronic police device and the local time t 1. In other embodiments, the trigger instruction carries a random number y corresponding to each front-end electronic police device, and the front-end electronic police device determines the initial reporting time of the state information according to the random number y. Each front-end electronic police device adopts a random algorithm to determine the initial reporting time, so that the problems of communication congestion and the like caused by the fact that a plurality of devices upload state information concurrently can be avoided.
202: and comparing the reporting time corresponding to each equipment identifier with the receiving time of the data management platform for receiving the state information to obtain the time difference value corresponding to each equipment identifier.
In one embodiment, the receiving time is the local time of the data management platform when the data management platform receives the status information, and the local time of the data management platform is determined by the data management platform based on a voting mechanism from the acquired current times returned by at least three different GPS timers.
In an embodiment, the time difference value is a difference between the reporting time and the receiving time, and the difference is a positive value, and may be in units of seconds or minutes, such as 45 seconds.

In one embodiment, this step includes: acquiring deployment position information of equipment corresponding to the equipment identification; determining a third threshold corresponding to the equipment identifier according to the deployment position information; and determining the device identifier with the time difference value larger than a third threshold value as the target device identifier. The distance between the front-end electronic police equipment at different deployment positions and the receiving server is different or the number of routers/switches that need to pass through is different, which results in different transmission delays between the front-end electronic police equipment at different deployment positions and the receiving server, and this embodiment determines the third threshold corresponding to the equipment identifier based on the deployment position information, and can reduce misjudgment caused by different transmission delays to the maximum extent, for example, the receiving server is deployed in a place, the deployment position information of the equipment corresponding to the equipment identifier 1 is a place B, the deployment position information of the equipment corresponding to the equipment identifier 2 is a place C, the distance between the place a and the place B is greater than the distance between the place a and the place C, the third threshold corresponding to the equipment identifier 1 can be configured to be 31 seconds, and the third threshold corresponding to the equipment identifier 2 is 30 seconds, and so on.

In one embodiment, the embodiment shown in fig. 2 further comprises, after step 204: monitoring whether the abnormal front-end electronic police equipment corresponding to the target equipment identification is recovered; and if the target equipment identification is recovered, stopping blocking illegal data corresponding to the target equipment identification. Whether the abnormal front-end electronic police equipment is recovered or not can be determined according to the next state information, for example, if the time difference value between the reporting time and the receiving time of the next state information of a certain abnormal front-end electronic police equipment is smaller than a third threshold value, it indicates that the abnormal front-end electronic police equipment is recovered to be normal, and normal storage of illegal data uploaded by the front-end electronic police equipment needs to be stopped to be blocked, so that the illegal data can be normally stored.
In one embodiment, the embodiment shown in fig. 2 further includes, after step 203: and sending a blocking instruction to the abnormal front-end electronic police equipment according to the target equipment identifier, wherein the blocking instruction is used for indicating the front-end electronic police equipment to stop uploading the collected illegal data.
