Description

Technical Field

[0001] This invention relates to the field of information processing, and more specifically to a fire monitoring data management system. Background Technology

[0002] In existing technologies, the application of intelligent fire protection systems typically relies on the Internet of Things (IoT) to ensure functionality. In intelligent fire management, sensor devices collect data and perform monitoring to ensure timely and accurate understanding of fire situations, enabling the intelligent fire protection system to provide reasonable and accurate fire warnings.

[0003] Sensors are widely used in the collection of fire information. Fire protection systems are usually set up using self-organizing network structures. Considering the practical issues of cost control and energy consumption control, how to reliably transmit fire monitoring data under a self-organizing network structure without increasing the system's processing burden has become a hot topic. Summary of the Invention

[0004] To address at least one of the aforementioned technical problems, this application proposes a fire monitoring data management system. The system includes a monitoring platform, which is equipped with several wireless sensor terminals and routers within each monitoring area. Each wireless sensor terminal and router within each monitoring area is equipped with a sensor network wireless module, enabling data transmission between the wireless sensor terminals and routers within each monitoring area, and between the central terminal and routers. Information exchange between monitoring areas is facilitated through router forwarding. The several wireless sensor terminals within the monitoring area form a self-organizing network. Among the wireless sensors are direct communication terminals, which are installed within each monitoring area and possess dual-network communication capabilities.

[0005] The router is connected to the monitoring platform, and each monitoring area transmits data to the monitoring platform through its own router. If communication between the router in any monitoring area and any wireless monitoring terminal is interrupted, the wireless sensor terminal in the interrupted monitoring area will switch its operating frequency and send a negotiation signal to the router on the pre-broadcast channel frequency. If no feedback is received when sending the negotiation signal, the wireless sensor terminal will receive the broadcast signal on the negotiation fallback frequency. The broadcast signal contains the ID information of the direct communication terminal in the monitoring area. The wireless sensor terminal obtains the ID information and sends the monitoring information to the direct communication terminal on the switched operating frequency. The direct communication terminal will send the information of the wireless sensor to the monitoring platform using direct communication.

[0006] Preferably, the monitoring platform is also used to pre-configure each wireless sensor terminal through a preset broadcast cycle. During normal communication, each wireless sensor terminal does not listen to the broadcast signal cycle. When the wireless sensor terminal has no network connection with the router in the monitoring area, it switches to listening to the broadcast channel.

[0007] Preferably, the wireless sensor terminal also includes a video monitoring terminal. The monitoring platform is further used to set up the video monitoring terminal within the wireless monitoring area. The triggering of the video monitoring terminal is coordinated with the alarm monitoring terminal of the monitoring platform. When an abnormal monitoring signal is detected, a trigger signal is sent to the video monitoring terminal through a direct communication terminal within the monitoring area, based on the regional distribution signal within the abnormal wireless area. The trigger signal carries the communication channel signal. When the video monitoring terminal obtains the communication channel signal, it performs a channel switching confirmation. When the monitoring platform obtains the switching confirmation information, it performs signal transmission on the switched channel.

[0008] Preferably, the video surveillance terminal and the direct communication terminal are pre-configured in the information of each monitoring area. The central terminal in each area periodically feeds back the information of the wireless sensors in the area. The monitoring platform identifies router failures, wireless sensor terminal link failures, and wireless sensor terminal failures by identifying the wireless monitoring data in each assigned monitoring area.

[0009] Preferably, the dual network communication capability of the direct communication terminal is specifically: short-range communication capability and data network communication capability.

[0010] Preferably, the short-range communication capability is Wi-Fi or Bluetooth communication, and the data network communication capability is 3G, 4G or 5G network.

[0011] Preferredly, the distinction between router failure, wireless node link failure, and wireless node failure is made using data identification information within the area. If no data is received from the router within a set period, the router is considered to be faulty. If no data is received from the corresponding wireless node within a set period, the wireless sensor terminal is considered to be faulty. If data is received from the wireless sensor terminal within a set period but the communication channel has a direct connection channel communication trigger, it is known that the communication link between the router and the wireless sensor terminal is faulty.

[0012] Priority is given that when the monitoring platform acquires abnormal monitoring data, the router terminals in the corresponding monitoring area will trigger a multi-channel communication mechanism. Each wireless sensor terminal will relay and forward the broadcast signal, and send information from the direct communication terminal in the broadcast signal. The wireless sensor terminal establishes a link connection with the direct communication terminal through a multi-channel or multi-link communication mechanism, and performs the propagation of monitoring information within the area.

[0013] Preferably, the direct communication terminal has its own power supply.

[0014] Priority is given to the monitoring platform sending the identification information of the direct communication terminal and triggering a channel configuration search in the broadcast channel allocated in the area where the monitoring data is located when abnormal monitoring data is detected.

[0015] This invention discloses an intelligent fire protection data monitoring and management system. The system includes a monitoring platform, which is equipped with several wireless sensor terminals and routers in each monitoring area. Each wireless sensor terminal and router in each monitoring area is equipped with a sensor network wireless module. By including direct communication terminals among the several wireless sensors, and setting up direct communication terminals in each monitoring area, the direct communication terminals have dual network communication capabilities. By performing terminal transmission, channel switching negotiation and confirmation, and comprehensive scheduling in direct communication via broadcast channels, the stability and timeliness of fire protection monitoring data transmission are ensured.

[0024] Example 1

[0025] like Figure 1 The intelligent fire management system shown is a fire monitoring data management system. The system includes a monitoring platform, and the monitoring platform is equipped with several wireless sensor terminals and routers in each monitoring area; wherein the wireless sensors include direct communication terminals.

[0026] The monitoring platform can be equipped with several wireless sensor terminals, a central terminal, and a router in each monitoring area. Optionally, the wireless sensor terminals may include a central terminal, which is used to centrally control the transmission of monitoring data within the group area. The central terminal is configured to not be in a sleep state. The central terminal periodically sends the status information of the sensor terminals, i.e., sensor nodes, within the group area to the router in its area.

[0027] Each wireless sensor terminal, central terminal, and router within each monitoring area is equipped with a sensor network wireless module, enabling data transmission between the wireless sensor terminals and the central terminal, between the wireless sensor terminals and the router, and between the central terminal and the router within each monitoring area. Information exchange is also possible between monitoring areas. A direct communication terminal with two communication capabilities is provided within each monitoring area. Several wireless sensor terminals within the area form a self-organizing network, which is a mesh network.

[0028] The router is connected to the monitoring platform, and each monitoring area transmits data to the monitoring platform through its own router. If communication between the router and any wireless monitoring terminal in any monitoring area is interrupted, the first wireless sensor terminal in the interrupted monitoring area will switch its operating frequency and send a negotiation signal to the router on the broadcast channel frequency. If no feedback is received after sending the negotiation signal, the wireless sensor will receive the broadcast signal on the negotiation fallback frequency. The broadcast signal contains information about the dual-communication-capable wireless sensors in the monitoring area, including at least ID information and location area information. The wireless sensor acquires the ID information and sends its own monitoring information to the dual-communication-capable terminal on the corresponding frequency or time slot. The dual-communication-capable sensor will send the information of the wireless sensor to the monitoring platform using a direct communication method.

[0029] Optionally, the information of the dual-communication-capable wireless nodes is pre-configured and transmitted on a set broadcast channel. When each wireless sensor is communicating normally, it does not perform periodic listening to the broadcast signal. When the wireless sensing terminal has no link with other wireless sensing terminals in the monitoring area, it switches to listening to the broadcast channel.

[0030] Optionally, the monitoring platform sets up video monitoring terminals within the wireless monitoring area. The triggering of the video monitoring terminals is coordinated with the alarm monitoring terminals of the monitoring platform. When abnormal monitoring information is detected, a trigger signal is sent through a wireless sensor with dual communication capabilities within the monitoring area based on the regional distribution signal within the abnormal wireless area. This triggers the video signal. The trigger signal of the video monitoring signal carries the communication channel signal. When the video monitoring terminal obtains the communication channel signal, it performs a channel switching confirmation. When the monitoring platform obtains the switching confirmation information, it performs signal transmission on the switched channel to ensure that the communication channel is received. This ensures that information from the abnormal signal occurrence area can be quickly transmitted on the negotiated channel, facilitating the receiving end to receive data on the corresponding channel. Simultaneously, the monitoring platform can evenly configure channels in different router areas.

[0031] The wireless sensing terminals in each area are wireless nodes. The video surveillance terminals and node information with dual communication capabilities are pre-configured in the information of each area. The wireless monitoring nodes in each area periodically feed back node information. The monitoring platform identifies wireless monitoring data in each area and distinguishes between router failures, wireless node link failures, and wireless node failures.

[0032] Optionally, the distinction between router failure, wireless node link failure, and wireless node failure is made using data identification information within the area. If no data is received from the router within a set period, the router is considered to be faulty. If no data is received from the corresponding wireless node within a set period, the wireless node is considered to be faulty. If wireless node data is received within a set period but communication is triggered by a direct connection channel, then the communication link between the router and the wireless node is considered to be faulty.

[0033] Optionally, the monitoring platform pushes information to the maintenance platform based on the status type. Optionally, the monitoring platform may push different warning messages based on the different fault types.

[0034] The terminal with dual communication capabilities includes short-range communication capability and data network communication capability. Optionally, the short-range communication capability is Wi-Fi or Bluetooth communication, and the data network communication capability is 3G, 4G, or 5G network.

[0035] When the monitoring platform acquires abnormal monitoring data, the router terminal in the corresponding area will trigger a multi-channel communication mechanism. The wireless sensor node will relay and forward the broadcast signal. The broadcast signal sends the node information of each relay with dual communication capability. The wireless sensor will perform the propagation of monitoring information in the area through a multi-channel or multi-link communication mechanism.

[0036] For example, if communication between a router and any wireless monitoring terminal within any monitoring area is interrupted, the first wireless sensor terminal within the interrupted communication monitoring area will switch its operating frequency. Specifically, this may further include channel detection between wireless routers and between a wireless router and a terminal: after the monitoring platform configures the wireless router to start under on-site network conditions, it probes the on-site network situation. In the case of pre-configured multi-link channels, the wireless router searches for the usage of each channel. Based on the obtained channel usage results, it selects an unoccupied channel.

[0037] Optionally, a controller is configured in the local area network of the wireless router. This controller controls the connection to the central terminal. The controller's automatic frequency adjustment and switching to an idle frequency channel includes: after powering on, the controller searches each channel in the field network one by one, sending a router search command in the default frequency channel and waiting for a response. The wireless router receiving the message will respond accordingly, with the response message containing the number of remaining connectable frequency channels. The search ends when the controller receives a response from a wireless router with a remaining capacity greater than 0. If the controller does not receive a response from a wireless router within a specified time, or if the router capacity in the response message is 0, the controller will similarly increase the current channel frequency by 1 MHz, switch to the new channel, and repeat the above process.

[0038] Prioritizing reliable connection, after the controller receives a message from the wireless router indicating remaining capacity greater than 0, the router will repeatedly send an acknowledgment message to the controller. If the controller responds correctly, thus establishing the communication link between the wireless router and the controller, the controller terminal sends a switchable operating frequency channel to the wireless monitoring terminal. If no response is received from the router after a specified number of automatic frequency hopping attempts, indicating that no working router has been found within the signal coverage area, the search process automatically exits, triggering the sending of the monitoring information to the dual-communication-capable terminal. The dual-communication-capable sensor will then use direct communication to send the wireless sensor information to the monitoring platform. Optionally, the controller can be configured with a dual-communication direct-connection terminal.

[0039] The monitoring platform acquires the aforementioned channel negotiation information, balances the channel frequency distribution in each router area, and executes comprehensive scheduling based on the channel negotiation information when it acquires channel anomaly monitoring data. Optionally, the aforementioned comprehensive negotiation and scheduling information is sent to the monitoring platform by the directly connected communication terminal.

[0040] like Figure 2 As shown, this system can be applied to and is compatible with third-party data platforms to provide data services.
