Abnormal analysis includes analysis of suspicious objects, climbing over and staying, throwing objects, smoke, fire, etc. When a situation occurs in the perimeter, the duty command room or the duty room will issue an alarm warning and it will be immediately displayed on the monitor. The duty personnel can lock the emergency information at the first time and can control the further occurrence of the emergency within the effective time.

[0041] The vehicle management module is used for dispatch management, maintenance management and private car management of vehicles. In the embodiment of the present invention, by establishing a vehicle information database of the detachment's vehicles, drivers and driving licenses, the dispatch management, maintenance management and private car management of vehicles are realized to ensure that the vehicle management is orderly and controllable.

[0042] The armory management module is used to follow and film the personnel entering the warehouse in real time through the face recognition system, and transmit the sensed gun dynamics to the control management background through the network through the active tag on the gun and record it. In the embodiment of the present invention, permissions are assigned to relevant personnel, and the armory is equipped with a face recognition system. When the door of the armory is opened, the personnel entering the warehouse are followed and filmed in real time. At the same time, the background monitoring system of the command room and the safety network automatically jumps to the follow-up screen, and uses an alarm prompt sound to prompt the supervisor to supervise. After the gun is taken out, the active tag attached to it transmits the sensed gun dynamics to the management background through the network and records it. If there is any abnormality, the alarm is triggered in time to improve the efficiency and accuracy of management and control.

[0043] The equipment warehouse management module is used to automatically open the exclusive single police equipment cabinet corresponding to the officers and soldiers when the equipment warehouse door is opened by deploying face recognition access control and linkage equipment cabinets, or to open all equipment cabinets through authorization of the control terminal. In the embodiment of the present invention, face recognition access control and linkage equipment cabinets are deployed in the equipment warehouse. After the officers and soldiers open the equipment warehouse door through face recognition access control, the exclusive single police equipment cabinet corresponding to the officers and soldiers is automatically opened separately. In case of emergency, all equipment cabinets can be authorized to be opened through the control terminal to deal with emergencies.

[0044] The fixed asset management module is used to realize dynamic management of fixed assets by registering, transferring and scrapping assets through the Internet of Things technology. In the embodiment of the present invention, fixed assets are managed by relying on the Internet of Things technology, and a variety of asset label templates are provided. Different templates can be selected to print asset labels according to needs. The fixed asset management module provides asset life cycle management such as registration, transfer, and scrapping of assets, realizes process management of the entire life cycle, and all processes need to be reported and approved to realize dynamic management of assets. It is also used to query assets according to different attributes and generate corresponding asset reports in a tabular or graphical manner.

[0045] The police equipment management module is used to manage the classification and standardization of police equipment assets through the Internet of Things technology, and to monitor police equipment in real time and dynamically. In the embodiment of the present invention, the Internet of Things technology is used to manage the classification and standardization of police equipment assets, and to monitor police equipment in real time and dynamically. In conjunction with digital maps, equipment registration, transfer, and scrapping process management can be achieved according to demand. The police equipment management module 6 can intelligently complete the procurement management of hardware equipment cabinets, record the total number of equipment in the warehouse, and the time when personnel enter and exit to collect them. The police equipment management module is also used to query police equipment according to different attributes, and generate corresponding asset reports in a tabular or graphical manner.

[0046] The intelligent camp management module is used to control the homes in the camp through intelligent software according to the daily work and rest schedule mode, integrating the home residential function and office function. In the embodiment of the present invention, the daily work and rest schedule mode includes: work mode, leisure mode, entertainment mode and rest mode. According to the daily work and rest schedule mode, different modes correspond to work tasks and daily life needs at different work and rest times. The homes in the camp are controlled by intelligent software, and controlled through media such as sound, light, and body movements to realize the combination of home residential function and office function, thereby improving the energy saving, intelligence and humanization of camp barracks management.

[0047] This embodiment proposes a camp security system, such as Figure 1 As shown, the specific steps include: access control module, encryption module, wireless sensor network module, security prevention analysis center and several local user devices;

[0048] Access control module, used to collect basic information of people who need to pass through the access control;

[0049] An encryption module is used to encrypt and compress basic information;

[0050] The wireless sensor network module is used to collect sensor data of various monitoring objects within the preset security protection range, and send the sensor data and compressed basic information to the security protection analysis center;

[0051] Security and prevention analysis center, used to analyze sensor data and compressed basic information;

[0052] The local user device is used to receive the analysis result.

[0053] Furthermore, the access control module, the encryption module, the wireless sensor network module, the security protection analysis center and the local user equipment are connected in sequence.

[0054] Specifically, the access control module uses the infrared imaging module and the face recognition module to preliminarily collect the identity information and body temperature report of the entering personnel, and transmits the collected information to the encryption module; the encryption module uses the cryptographic algorithm of the password module to establish a secure channel between the local user device and the remote server to realize encrypted transmission of data; the wireless sensor network collects the sensor data of various monitored objects within the preset security prevention range, and sends it to the security prevention analysis center; the security prevention analysis center determines whether the received sensor data and encrypted basic information are within the normal monitoring range, and generates warning information when the judgment result is no, and sends the generated warning information to the predetermined local user device.

[0055] Furthermore, the access control module includes: an infrared imager unit and a face recognition unit.

[0056] Specifically, the access control module includes access control management components, personnel card issuance components, and visitor management components. It uses cards, faces, fingerprints and other media to realize intelligent applications such as identity recognition and access control. It adopts a combination of B / S architecture configuration and C / S architecture control to integrate resources, cards, personnel, permissions, etc., and realize device access, business configuration and functional application.

[0057] More specifically, the infrared imager unit: the camera target size is 1 / 2.8 inches2, the video output supports 2560×1440@25fps, the resolution is not less than 1400TVL, the infrared distance can reach 150 meters, and it supports 40x optical zoom. For example, Hikvision's DS-2DE74XYZIW-A.

[0058] Face recognition unit: Intelligent network camera with a maximum resolution and frame rate of 2560×1440 and 25 frames per second, for example, Hikvision's DS-2CD7A4X-AB.

[0059] Face access control: 7-inch LCD touch screen; the screen supports multi-touch operation; for example, Hikvision's DS-K1T671M-3XF.

[0060] Furthermore, the encryption module uses cryptographic algorithms to establish a secure channel between the local user device and the remote server to achieve encrypted data transmission.

[0061] Furthermore, the wireless sensor network includes: a sink node, multiple cluster heads and multiple sensor nodes, wherein the sink node is wirelessly connected to a security prevention and analysis center; each sensor node includes at least one wireless sensor for sensing sensor data; each sensor node selects the nearest cluster head to join the cluster, the cluster head collects the sensor data collected by the sensor nodes in its cluster, and sends the collected sensor data to the sink node, so that the sink node integrates the sensor data and sends it to the security prevention and analysis center; the sensor node selects a direct or indirect communication mode to send the collected sensor data to the corresponding cluster head according to the distance from itself to the corresponding cluster head.

[0062] Furthermore, the sensor node selects a direct or indirect communication mode to send the collected sensor data to the corresponding cluster head according to the distance from the sensor node to the corresponding cluster head, including: when the distance between the sensor node and the corresponding cluster head does not exceed the current distance threshold, the collected sensor data is directly sent to the corresponding cluster head; when the distance between the sensor node and the corresponding cluster head exceeds the current distance threshold, among the sensor nodes in the cluster that are closer to the cluster head, the sensor node with the closest distance is selected as the next hop node, and the collected sensor data is sent to the next hop node, so that the next hop node forwards the collected sensor data until the collected sensor data is sent to the corresponding cluster head.

[0063] Specifically, in this embodiment, the sensor node can select the direct or indirect communication mode to send the collected sensor data to the corresponding cluster head according to the distance from the sensor node to the corresponding cluster head, thereby improving the flexibility of routing between the sensor node in the cluster and the corresponding cluster head. In this embodiment, the distance threshold is used as the standard for the sensor node to select the direct or indirect communication mode to send the collected sensor data to the corresponding cluster head, and the initial value of the distance threshold is further given to ensure that there are an appropriate number of sensor nodes communicating directly with their corresponding cluster heads at the beginning, thereby ensuring the reliable collection of sensor data.

[0064] In one embodiment, the cluster head exchanges information with the sensor nodes in its cluster every preset period ΔT0 to obtain the energy information and location information of all the sensor nodes in its cluster. The cluster head calculates the current remaining energy average value Eavg1 of all the sensor nodes whose distances do not exceed the current distance threshold and the current remaining energy average value Eavg2 of all the sensor nodes whose distances exceed the current distance threshold based on the energy information and location information. If the following conditions are met, the cluster head updates the current distance threshold and broadcasts the updated current distance threshold to all the sensor nodes in its cluster:

[0065]

[0066] Among them, ε is the preset energy ratio coefficient, and the value range of ε is [0.40, 0.45].

[0067] In this embodiment, the cluster head determines whether the distance threshold is updated every preset period ΔT0, and performs the distance threshold update operation according to the determination result, thereby avoiding energy consumption caused by unnecessary threshold distance update. In this embodiment, the energy information and location information of the sensor nodes in the cluster are used as the measurement standard, and a judgment mechanism is proposed accordingly. This mechanism drives the cluster head to increase the current distance threshold in time when the average energy of all sensor nodes whose distance from the cluster head does not exceed the current distance threshold is relatively low, thereby driving more sensor nodes in the cluster to communicate directly with the cluster head, which is beneficial to reducing the load of the sensor nodes that originally communicated directly with the cluster head, balancing the energy of each sensor node in the cluster, and improving the stability of the operation of the wireless sensor network 1.

[0068] In one embodiment, the updating formula of the distance threshold is:

[0069]

[0070] Where, ST(A)′ is the distance threshold after cluster head A updates, ST(A) is the distance threshold before cluster head A updates, and m(A) is the number of sensor nodes whose distance does not exceed the current distance threshold.

[0071] When ST(A)′ reaches a preset upper distance limit or the number of updates reaches a preset threshold, the updating of the distance threshold is stopped.

[0072] This embodiment further proposes an updating formula for the distance threshold. When updating the distance threshold, this embodiment takes into account the actual deployment of the sensor nodes, and uses the difference between the relative average energy ratio and the preset energy ratio coefficient as the distance threshold increase coefficient, which is beneficial for making the increased distance threshold more suitable for the current network situation and ensuring that an appropriate number of sensor nodes are added to the set of sensor nodes that communicate directly with the cluster head.

[0073] In one embodiment, when the distance between the cluster head and the sink node does not exceed the preset upper limit of the distance, the collected sensor data is directly sent to the sink node. If the distance to the sink node exceeds the preset upper limit of the distance, the cluster head selects the closest cluster head as the next hop node among other cluster heads that are closer to the sink node.

[0074] Furthermore, the security prevention analysis center is provided with a storage module for storing sensor data that is not within the normal monitoring range.

[0075] Furthermore, the Security Prevention Analysis Center also has a comprehensive analysis alarm experience classification library to store overall solution use cases for various hazard alarm events.

[0076] Specifically, the security analysis center has video intelligent analysis, including face and body analysis algorithm authorization, analysis module, image database module, big data module and software and hardware. For example, Hikvision's DS-IX2001-A7U / LX (standard configuration).

[0077] More specifically, the intrusion alarm is composed of an alarm system consisting of an alarm host and a detector in cooperation with a platform to deploy defense zones. After the detector detects an intrusion, it reports it to the platform through the alarm host, making it easy for users to quickly perceive and efficiently handle intrusions and unexpected events in the defense zone, protect the safety of the user's defense zone, and realize an instant prevention system with functions such as detection, reporting, and alarm handling.

[0078] Dynamic environment monitoring uses sensors to collect and record environmental data such as temperature, humidity, voltage, and dust, and supports threshold setting for alarms. It conducts real-time detection of materials and the environment, and notifies personnel to handle them, achieving unmanned operation and improving the level of automated management, allowing users to centrally control materials.

[0079] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
