Example 1

In the network where the method described in Figure 1 is applied, an intelligent fire protection communication network is constructed. The network includes a central server, a group control node and a group node, and for communication in the group control node, a key relay node is set in the group control node; in the fusion application of BIM technology in the method, the method includes The information transmitted for the fire signal is divided into uplink and downlink communication channels, and the downlink channel transmits the control broadcast signal sent by the control node to the IoT device (node in the group), and the IoT device receives the The control broadcast signal matches its own broadcast identification information according to the identification signal in the control broadcast signal. When identifying the identification information of its own group, it reads the data in the control broadcast signal, otherwise it maintains a dormant state. The Internet of Things device detects its own cached data, and when there is cached data, it triggers the information to be sent to the nodes in the group, and the control node in the group sends the above information through the uplink channels allocated by the group time slot to send data.

Optionally, after the overall initialization of the system, the group control node enters the waiting state. When the central server activates the working state of the nodes in the group, the group control node enters the monitoring state, and the current state of all the nodes in the group All feed back to the central server. After the central server receives the information, it will feed back a time signal to the group nodes, that is, the next uplink channel information will be used as the reference time for the next feedback to the central server.

When the uplink channel comes, the node devices in the group are turned off and enter a dormant state, only receiving the control signal of the group node. When an abnormal situation is detected in the group node, the group node will automatically wake up and report to the group in time The group control node sends the current state.

In different implementation manners, the group control node periodically detects the cached data of the nodes in the group, the cached data is set with a priority identifier, and is sent to the group control nodes in the group according to the order of the priority identifiers, The group control node sends the above information to the central server through the time slot of the uplink channel allocated by the group; when there is emergency priority data, the nodes in the group trigger the emergency multi-chain communication mechanism, and the emergency control sent by the central server The broadcast signal is sent to the corresponding group control node, and the corresponding group control node updates and controls the information of the group according to the emergency control broadcast signal, and executes the relay and forwarding of the emergency control broadcast information within the group.

Optionally, the communication transmission data format communication data takes reliability and efficiency into consideration. The data frame includes the frame header, frame tail, identification, address, data and verification parts. The frame header is opened with a setting character, and the frame tail is used The end of the character; the address is a single-byte address, and 64 bytes can be used as an option. The addresses of the cache space of each group node in the address allocation are not connected, and a certain degree of fault tolerance is maintained; the data part is one byte.

Preferably, the group control node updates the information of its own group according to receiving the control broadcast signal, and when receiving the control signal sent by the service control center, that is, the central server, the Compare the identity of its own group, and execute the relay and forwarding of control broadcast information within the group.

In the emergency multi-chain communication mechanism, the information of the group can only be accessed periodically in real time by the group control node to the cached data in the group, and when the cached data meets the threshold, trigger the nodes send data. This saves node energy and is beneficial to nodes for information detection and deployment of relay transmission resources in emergency situations. The nodes in the data group periodically detect the data information in the fire protection space to which they belong. When the detected data exceeds the threshold, such as when the smoke alarm finds that the smoke exceeds the critical value, high information is set in the sent data frame Transmission priority, the high priority is the first to trigger communication with the group control node. The group control node controls neighboring nodes of the emergency signal sending node to transmit channel information. The adjacent nodes will vacate their own uplink bandwidth as a relay node to receive the signal sent by the emergency smoke alarm first, and at the same time trigger the adjacent nodes to perform smoke detection, and the control node will package the smoke information and time information forwarded by the group node Sending, the central control server sends control information and early warning information according to the distribution map of different smoke detectors in the group nodes.

According to the location information, solubility information, smoke clock information and other information of the smoke controller in the group information, the central server matches the above information with the smoke diffusion characteristic map in the control service center, and compares the information of the diffusion floor in the expected clock Do time-sharing and distance alarm transmission.

The smoke diffusion model can specifically be the detection data to be obtained by using numerical simulation to simulate the fire situation, that is, the indoor and outdoor air flow scenarios of a specific building, and the spreading direction of fire points generated inside several buildings under the air flow conditions The speed, diffusion direction and concentration distribution of fire smoke inside and outside the building are used as the key parameters of the fire, and the fire situation inside the building is simulated with a panoramic high degree of restoration, and the parameter characteristic map of the simulation model is obtained.

In an optional way, other variables such as wind speed and direction in indoor and outdoor spaces, smoke concentration, and turbulent diffusion intensity can be introduced; through the above parameters, input them into the characteristic table of the smoke diffusion model to obtain and obtain the diagram of the smoke diffusion trajectory, in the corresponding situation Next, according to the risk assessment results, obtain the corresponding escape and rescue routes, emergency plans, floor-by-floor, and time-sharing to send corresponding group control nodes to send fire information alarms, triggering the multi-link relay communication mode.

The transmission of the time-division and distance alarm is directly sent to the control node corresponding to the group node, and only sent to the group control node, so as to save transmission bandwidth. After the different group control nodes obtain the control signals with high priority, they send response signals to the alarm nodes in different groups according to the trigger sequence, so as to evacuate the crowd.

Exemplarily, before the central server and the group control node communicate, the central server and the group control node device can first negotiate or communicate the link identifier, and establish a link identifier and a link or a station on a link (that is, a node ) correspondence. In data transmission, there is no need to transmit a large amount of signaling information to indicate the link or the site on the link, and only the link identifier is carried in the transmitted information, which reduces signaling overhead and improves transmission efficiency.

In addition, when the group control node establishes the cluster communication, the management frame sent carries an element including the link identification information field and the identification ID information for communication with the group, and each link identification information field identifies its transmission to the central server Correspondence between group control stations or relay nodes on optional links. Each link identification information field includes a link identification. Optionally, the link identifier may be a MAC address, a channel number, and the like.

Optionally, the trigger control information and early warning information also include the group control node, according to the smoke dispersion solubility, to automatically trigger the descent of the fire shutter floors in the corresponding group floors.

Optionally, the central server triggers the corresponding group control node according to the characteristic graph, and acquires and collects the WIFI signal terminals of nearby users. The information pushes the planned escape route to users in the fire area; the escape route is matched with the location information of the user terminal, and when the user terminal location information deviates from the escape route, it will flash through the detection sensor node information in the group , providing guidance to the user.

In an optional embodiment, a group control node is selected or set in the setting of each floor as a border router of the floor, and the optional group control node is used as a routing node in each floor, wherein each Each of the routing nodes on the network creates and maintains a neighbor table, and the neighbor table records each routing node's neighbors on the network routing nodes or/and border routers.

For the transmission of fire information in groups in the network. In the preferred embodiment, it is transmitted through the multi-node path in the border router. In order to ensure the interruption of different fire sensor signal routes in the fire, the relay transmission mode is configured in the group. For data transmission between groups , in order to save system resources, each routing node does not need to maintain a complete dynamic routing table. In the group fire control node, each router node as a network creates and maintains (i.e. periodically updates the neighbor table) a neighbor table, and the neighbor table records that the neighbors of the network router node are in the network router node (single-hop routing) Or/and border routers, that is, each neighbor table records the relationship between each on-net routing node and other on-net routing nodes or/and border routers that constitute a direct wireless link, and only needs to maintain the neighbor table of the adjacent group control node. , taking point C as an example, when it is surrounded by three nodes, E, F, and G, it is only necessary to maintain three relationship tables of C-E, C-F, and C-G to form a neighbor table.

Exemplarily, in combination with the previous multi-link establishment between the central server and the control group node, during the multi-link establishment association process, the central server and the group control node device negotiate multiple link identification information fields; In the communication of , the central server and the group control node can characterize a node in the multi-link device by using the link identifier. Optionally, the dynamic transformation can be updated in real time according to the path information in the link. The construction of the multi-link device information is based on the change of the adjacent nodes. information, replace or update relay data information, and ensure that data transmission can be relayed. For the identification information in the multi-link establishment process, for the group communication nodes, the similar different detection nodes also include an adjacent node information table. When an emergency occurs, the multi-link communication mechanism is triggered.

When the control node in the group receives an abnormal situation, it detects the signal strength, routing depth and the number of connected nodes of each routing node in the network, and selects it by the processing node according to the signal strength, routing depth and the number of connected nodes path. Optionally, the key relay node, which is a group control node with its own power supply, is used as a processing node to process the path parameters. The routing depth is the minimum number of hops when each on-network routing node is connected to the border router. Every time an on-network routing node passes through, it hops once. The number of connected nodes is the number of nodes already connected to each routing node. The number of relay forwarding nodes or terminal nodes.

Optionally, the central server in the server end also includes, according to the user terminal location information obtained by the group control node, obtaining a three-dimensional model diagram established by BIM technology, and realizing group Information acquisition of group signals.

Optionally, according to the smoke diffusion model, for the pre-triggered self-provided power supply information of the key nodes in the group control node, at the same time, according to the pre-configured range, the group control node with the power supply sends a message For forwarding, the self-contained power supply information control group node information may be identified in the multi-link establishment identifier or broadcast information. The group control node in the disaster-stricken campus receives and triggers the information of the self-contained power control node, and performs relay transmission of information through it and the location information of the troubled user. As shown in Figure 2, this method can also be applied to an intelligent fire management platform to process monitoring information.
