Description

Technical Field

[0001] The present invention belongs to the field of positioning monitoring systems, and specifically relates to a Beidou electronic fence safety risk monitoring system in an electric power scenario. Background Art

[0002] The Beidou system's round-the-clock, high-precision positioning services, attitude measurement, and timing capabilities support the construction and development of smart grids, ensuring the security of grid spatiotemporal location services. However, in densely populated areas and with various signal-interfering devices, Beidou positioning signals may create blind spots, making it impossible to effectively monitor relevant monitoring targets in these blind spots, leading to increased safety risks. This is especially true for installed Beidou positioning base stations, which are required to effectively monitor and manage all personnel and vehicles within their monitoring areas in power grid scenarios. Blind spots in certain areas can lead to heightened safety risks. Summary of the Invention

[0003] In response to the problem that existing risk monitoring systems lack effective monitoring of regional blind spots, the present invention provides a Beidou electronic fence safety risk monitoring system in power scenarios.

[0004] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0005] A Beidou electronic fence safety risk monitoring system in power scenarios includes a Beidou positioning unit, a Beidou electronic fence setting unit, a regional blind spot data acquisition unit, a blind spot safety basic data acquisition unit, a data storage unit, and a safety early warning unit;

[0006] Beidou positioning unit, used to collect and locate target location data of the user receiving end in real time;

[0007] The Beidou electronic fence setting unit sets the Beidou positioning data collection range based on the installation location of the Beidou positioning base station. When the target position data collected by the Beidou positioning unit exceeds or a new target enters the Beidou electronic fence range, it is considered to have entered or exited the Beidou electronic fence;

[0008] Regional blind spot data acquisition unit, identifies the blind spot boundary and obtains the Beidou positioning data range of the regional blind spot;

[0009] The blind spot safety basic data acquisition unit collects all basic data that may cause safety risks in the blind spot through multiple sensors;

[0010] A data storage unit for storing target position data, Beidou positioning data collection range, and regional blind area Beidou positioning data range;

[0011] The security warning unit obtains and stores target location data, Beidou positioning data collection range and regional blind area Beidou positioning data range in real time; verifies the identity of the target entering and exiting the Beidou electronic fence and issues security warnings for targets within the regional blind area Beidou positioning data range.

[0012] Furthermore, the BeiDou positioning unit includes a plurality of BeiDou satellites, a BeiDou positioning base station and a user receiving terminal;

[0013] The Beidou positioning base station obtains valid monitoring data within the Beidou positioning data collection range through registration authorization;

[0014] The user receiving end is set at the user end and is a data terminal used to receive and send positioning signals.

[0015] Furthermore, the steps to set the Beidou positioning data collection range are as follows:

[0016] Obtain effective monitoring data within the Beidou positioning data collection range through the global positioning website;

[0017] The boundary value of the Beidou positioning data collection range is used as the electronic fence monitoring boundary value.

[0018] Furthermore, detailed steps to verify the target's identity when entering and exiting the Beidou electronic fence are as follows:

[0019] When the target enters or exits the electronic fence monitoring boundary value, it is first determined whether it carries a trusted receiver or a mobile terminal trusted user;

[0020] If the user is a receiver carrying a credit card or a mobile terminal credit card user, he / she will be determined as a user with access permission;

[0021] If there is no credit-authorized receiver or mobile terminal credit user, it is determined to be a new user or an abnormal risk target.

[0022] Furthermore, the security warning unit acquires the location data of new users or abnormal risk targets in real time, and obtains the entry identity information of the new users, and sends it to the Beidou positioning base station monitoring end manager to authorize entry and exit of the Beidou electronic fence;

[0023] If authorized by the administrator, the new user will be a user with entry and exit permissions;

[0024] If the new user does not provide entry identity information and the administrator's authorization is not passed, the target will be judged as an abnormal risk target and will not be allowed to enter or exit the Beidou electronic fence area.

[0025] Furthermore, the detailed steps to identify the blind area boundary and obtain the Beidou positioning data range of the regional blind area are as follows:

[0026] Analyze the existence of objects that block Beidou positioning signals and large devices that interfere with Beidou positioning signals based on the scope of the Beidou electronic fence area;

[0027] Extract the Beidou positioning data range from the blind area boundaries covered by objects that block Beidou positioning signals and large devices that interfere with Beidou positioning signals;

[0028] The extracted blind spot boundary is subjected to coordinate transformation within the Beidou positioning data range, converted into spatial three-dimensional coordinate data, and the blind spot boundary is obtained.

[0029] Furthermore, based on the spatial three-dimensional coordinate data, the steps of obtaining the blind spot boundary are as follows:

[0030] First read the GPS coordinate point data;

[0031] Then the boundary contour is calculated using the convex hull algorithm;

[0032] Finally, the boundary contour is drawn using the matplotlib library.

[0033] Furthermore, the detailed steps of the safety warning unit safety warning are as follows:

[0034] Provide primary warning for abnormal risk targets that are not allowed to enter or exit the Beidou electronic fence area;

[0035] For authorized users and abnormal risk targets that enter the Beidou positioning data range (drawn boundary outline) of the regional blind area, basic data that is likely to cause security risks is collected at the same time;

[0036] Determine whether the basic data that is prone to security risks exceeds the preset security risk data range; for example, if the security risk data such as temperature, humidity, voltage and current in the blind area undergo abnormal changes and exceed the preset security risk data range.

[0037] If it exceeds the preset safety risk data range, it is determined that there is an accident that creates a safety risk in the blind spot and an advanced warning is issued;

[0038] If it does not exceed the preset security risk data range, continue to observe the basic data of the blind areas that are prone to security risks entered by authorized users.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] By deploying Beidou electronic fences, acquiring real-time location data of targets entering the Beidou electronic fences, acquiring the Beidou positioning data range of blind spots, and collecting basic safety data of blind spots, we conduct safety early warning analysis on the identities of targets entering and leaving the Beidou electronic fences and the target behaviors within the Beidou positioning data range of the regional blind spots; ensuring effective monitoring of all personnel and vehicles within the monitoring area in power scenarios, and at the same time conducting safety analysis on the behaviors of target personnel in regional blind spots to achieve effective monitoring of regional blind spots.
