[0030] Embodiment 1

[0031] Figure 1 A flowchart of a fire information forwarding method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of forwarding fire information in a data center computer room. The method can be executed by a fire information forwarding device, which can be implemented in the form of hardware and / or software. Figure 1 As shown, the method includes:

[0032] Step S101: determining the forwarding priority of each target sensor node through the source sensor node to which the fire information is to be sent.

[0033] Optionally, before determining the forwarding priority of each target sensor node through the source sensor node to send the fire information, the method further includes: determining the transmission control range of the source sensor node itself; and taking the sensor nodes within the control transmission range as the target sensor nodes.

[0034] Optionally, determining the forwarding priority of each target sensor node through the source sensor node to which the fire information is to be sent includes: determining the remaining power of each target sensor node and the distance to itself through the source sensor node to which the fire information is to be sent; and determining the forwarding priority of each target sensor node according to the remaining power and the distance.

[0035] Specifically, in this embodiment, different types of sensors, such as smoke sensors, gas sensors, and temperature sensors, are arranged at different locations in the data room. Different types of sensors are used to collect smoke concentration, gas concentration, and temperature values ​​in the fire scene in the data room, and the collected data are used as fire information. Different types of sensors are networked using Bluetooth mesh technology, and each sensor is used as a node in the network, and the fire information is forwarded through the sensor node. In addition, the intelligent fire detection system also includes monitoring equipment. This embodiment does not limit the specific structure included in the intelligent fire detection system, and the fire information is transmitted to the monitoring equipment through the forwarding of each node in the network, and is visualized on the monitoring equipment, so that the monitoring personnel can quickly and timely obtain the fire situation in the data center room, and adopt different disaster relief plans according to the severity of the fire.

[0036] It should be noted that in this embodiment, if the network adopts a flooding transmission mode when broadcasting data, that is, all nodes in the network forward data once, a large number of unnecessary data copies will be generated in the network, and unnecessary data forwarding will consume the energy of the nodes, thereby increasing the energy consumption of the entire network. Therefore, in this embodiment, in order to solve the problems of high energy consumption and data packet collision involved in the process of fire information forwarding, a Bluetooth adaptive energy optimization routing algorithm is proposed. Through this algorithm, the non-essential node forwarding behavior can be significantly reduced, thereby controlling the generation of redundant data packets in the network. The Bluetooth adaptive energy optimization algorithm mainly involves introducing a priority system for sensor node forwarding, thereby providing a judgment standard for limiting the unnecessary forwarding behavior of sensor nodes; by delaying the forwarding of nodes, the possibility of synchronous data transmission of multiple sensor nodes is reduced, and the problem of data packet collision is effectively alleviated; unnecessary data forwarding between sensor nodes is suppressed, and the strategy of forwarding priority and introducing forwarding delay is combined to minimize the number of forwarded sensor nodes and redundant data packets in the network, thereby solving the problem of energy waste. Therefore, the essence of the adaptive energy optimization routing algorithm is to determine the forwarding priority of each adjacent node, so as to set their respective forwarding delay times. At the same time, according to the set forwarding delay time, each node performs a delay operation. Finally, according to the node forwarding suppression strategy, after the delay, it evaluates whether each node has the authority to transmit data, thereby restricting the forwarding behavior of certain nodes.

[0037] Among them, the source sensor node to send fire information will take the sensor nodes in the network within its transmission control range as target sensor nodes, and obtain the remaining power of each target sensor node and the distance from the source sensor node, and determine the forwarding priority of each target sensor based on the above two parameters.

[0038] In a specific implementation, Figure 2 As shown, it is a structural diagram of an intelligent fire detection system. The network of the system consists of 16 sensor nodes. When sensor node 1 needs to forward the generated fire information, that is, data packet p, in the network to upload it to the monitoring device in the system, sensor node 1 serves as the source sensor node for this forwarding. Among them, the sensor nodes located within the transmission control range of sensor node 1 include: 2, 3, 4, 5, 6, 7 and 8. The seven sensor nodes located within the transmission control range are taken as target sensor nodes, and sensor node 1 needs to forward data packet p to all target sensor nodes. In order to avoid data packet collision during the forwarding process, the forwarding priority of the seven target transmission nodes will be determined. Specifically, the forwarding priority of each target sensor can be determined based on two parameters: the remaining power and the distance from the source sensor node. For example, the priority can be determined based on the product result of the remaining power and the distance. Of course, the specific method for determining the forwarding priority is not limited in this embodiment. For example, the target sensor node 4 is determined to be level one, 2 is level two, 3 is level three, 6 is level four, 7 is level five, 5 is level six, and 8 is level seven by calculation, and the priority is reduced in sequence. Of course, this embodiment is only an example and does not limit the level of the forwarding priority of each target sensor.

[0039] Step S102: The source sensor node determines the forwarding delay time of each target sensor node according to the forwarding priority.

[0040] Optionally, determining the forwarding delay time of each target sensor node according to the forwarding priority by the source sensor node includes: determining the forwarding weight of each target sensor node according to the forwarding priority by the source sensor node; and determining the forwarding delay time of each target sensor node according to the forwarding weight.

[0041] Optionally, after the source sensor node determines the forwarding delay time of each target sensor node according to the forwarding priority, the method further includes: sorting the target sensor nodes in ascending order of the forwarding delay time to obtain a fire information forwarding sequence.

[0042] Specifically, in this embodiment, after determining the forwarding priority of each target sensor node, the forwarding weight of each target sensor node is determined according to the forwarding priority, and the pre-configured forwarding time is also obtained, so as to determine the forwarding delay time of each target sensor node according to the product result of the forwarding weight and the forwarding time, and the higher the forwarding priority, the smaller the relative forwarding delay time, that is, the information sent by the source sensor node is received first, so the forwarding delay time of the target sensor nodes 4, 2, 3, 6, 7, 5, and 8 in the above example increases in sequence, for example, the forwarding delay time of the target sensor node 4 is 1 second, the forwarding delay time of the target sensor node 2 is 2 seconds, the forwarding delay time of the target sensor node 3 is 3 seconds, the forwarding delay time of the target sensor node 6 is 4 seconds, the forwarding delay time of the target sensor node 7 is 5 seconds, the forwarding delay time of the target sensor node 5 is 6 seconds, and the forwarding delay time of the target sensor node 8 is 7 seconds. Of course, this embodiment is only an example, and the specific values ​​of each target sensor node are not limited.

[0043] It should be noted that, in this implementation, the above-mentioned target sensor nodes will be excluded in the order of forwarding delay time from small to large to obtain the fire information forwarding sequence, so that the subsequent source sensor nodes will forward the fire information based on the fire information forwarding sequence. For example, the source sensor node will forward the data packet p based on the order of target sensor nodes 4, 2, 3, 6, 7, 5, and 8. Of course, this implementation is only an example for illustration, and does not limit the specific content of the fire information forwarding sequence.

[0044] Step S103 : for each target sensor node, when the forwarding delay time ends, the receiving state of the target sensor node is obtained.

[0045] Specifically, the target sensor node 4 will first receive the data packet p and forward it. Once the target sensor node 4 starts the forwarding process, such as Figure 2 As shown, sensor nodes 7 and 8 located within the transmission control range of target sensor node 4 can immediately receive data packet p forwarded by target sensor node 4, and target sensor node 4 serves as a new source sensor node for target sensor nodes 7 and 8, and the time for receiving data packet p will be advanced. For example, assuming that sensor node 4 sends data packet p to sensor node 7 immediately after receiving it, the time for target sensor node 7 to receive data packet p will be advanced from 7 seconds to 1 second. Of course, this embodiment is only an example and does not limit the specific time for each target sensor node to receive data packet p.

[0046] Among them, after the forwarding delay time of the target sensor node 2 of 2 seconds is over, the receiving state of the target sensor node 2 will be obtained. Since the target sensor node 2 is not within the transmission control range of the target sensor node 4, the target sensor node does not receive the data packet forwarded by the target sensor node 4, so the receiving state of the target sensor node 2 will be obtained as received. Similarly, when the forwarding delay time of the target sensor node 7 is over, since the target sensor node 7 has received the data packet p forwarded by the target transmission node 4 in advance, the receiving state of the target sensor node 7 can be obtained as not received. Of course, this embodiment is only an example, and does not limit the receiving state obtained by each target sensor node.

[0047] Step S104: when the receiving state of the target sensor node is received, suppressing forwarding of the target sensor node.

[0048] Optionally, when the receiving state of the target sensor node is received, forwarding of the target sensor node is suppressed, including: when the receiving state of the target sensor node is received, deleting the target sensor node from the fire information forwarding sequence; and stopping the source sensor node from forwarding the fire message to the deleted target sensor node.

[0049] Optionally, the method further includes: when the receiving state of the target sensor node is not received, forwarding the fire information to the target sensor, so that the target sensor forwards the fire information within its own transmission control range; and receiving the forwarding result of the target sensor node through the source sensor node.

[0050] Specifically, when the source sensor node obtains the receiving state of the target sensor node as not received, it directly forwards the data packet p. However, when the receiving state is received, the target sensor node is deleted from the fire information forwarding sequence, and the source sensor node stops forwarding the fire message to the deleted target sensor node. For the above example, when the receiving state of the target sensor node 7 is received at the 7th second, in order to avoid repeated forwarding of the data packet, the source sensor node 1 will not send the data packet p to the target sensor node 7 again, thereby effectively reducing the number of times the source sensor node 1 forwards the data packet p, reducing the energy consumption of the source sensor node p, and thus improving the endurance of the source sensor node 1. Of course, in this embodiment, only sensor node 1 is used as an example to illustrate the source sensor node that sends fire information. Since each sensor node in the network has the situation of sending and receiving information, any sensor node in the network that sends fire information can be used as a source sensor node. The specific forwarding principle is the same as that of sensor node 1, and it will not be repeated in this embodiment. Therefore, in this embodiment, the frequency and number of communication of sensor message forwarding are intelligently adjusted according to the current energy consumption status and network environment status of the sensor through the adaptive energy optimization algorithm. In the event of a fire with insufficient energy supply, unnecessary data communication and forwarding between nodes is reduced, and the network's endurance is enhanced, thereby maximizing endurance time.

[0051] In the implementation mode of the present application, by determining the forwarding delay time of each target sensor node according to the priority, and forwarding each target sensor node according to a different forwarding delay time, the risk of data packet collision is reduced, thereby improving the stability of information forwarding, and when it is determined that each target sensor node has received the fire message sent by the target sensor node with a higher priority, the source sensor node does not need to repeatedly forward it to it, thereby effectively reducing the unnecessary energy consumption of the source sensor node and improving the endurance performance of the node.

[0052] Embodiment 2

[0053] Figure 3 This is a flowchart of a fire information forwarding method provided by Embodiment 2 of the present invention. This embodiment is based on the above embodiment. When the receiving state of the target sensor node is received, after suppressing forwarding of the target sensor node, it also includes: obtaining the signal strength of each sensor node, and updating the connection state of each sensor node according to the signal strength. Figure 3 As shown, the method includes:

[0054] Step S201: determining the forwarding priority of each target sensor node through the source sensor node to which the fire information is to be sent.

[0055] Optionally, before determining the forwarding priority of each target sensor node through the source sensor node to send the fire information, the method further includes: determining the transmission control range of the source sensor node itself; and taking the sensor nodes within the control transmission range as the target sensor nodes.

[0056] Optionally, determining the forwarding priority of each target sensor node through the source sensor node to which the fire information is to be sent includes: determining the remaining power of each target sensor node and the distance to itself through the source sensor node to which the fire information is to be sent; and determining the forwarding priority of each target sensor node according to the remaining power and the distance.

[0057] Step S202: The source sensor node determines the forwarding delay time of each target sensor node according to the forwarding priority.

[0058] Optionally, determining the forwarding delay time of each target sensor node according to the forwarding priority by the source sensor node includes: determining the forwarding weight of each target sensor node according to the forwarding priority by the source sensor node; and determining the forwarding delay time of each target sensor node according to the forwarding weight.

[0059] Optionally, after the source sensor node determines the forwarding delay time of each target sensor node according to the forwarding priority, the method further includes: sorting the target sensor nodes in ascending order of the forwarding delay time to obtain a fire information forwarding sequence.

[0060] Step S203 : when the forwarding delay time of each target sensor node ends, the receiving state of the target sensor node is obtained.

[0061] Step S204: when the receiving state of the target sensor node is received, suppressing forwarding of the target sensor node.

[0062] Optionally, when the receiving state of the target sensor node is received, forwarding of the target sensor node is suppressed, including: when the receiving state of the target sensor node is received, deleting the target sensor node from the fire information forwarding sequence; and stopping the source sensor node from forwarding the fire message to the deleted target sensor node.

[0063] Optionally, the method further includes: when the receiving state of the target sensor node is not received, forwarding the fire information to the target sensor, so that the target sensor forwards the fire information within its own transmission control range; and receiving the forwarding result of the target sensor node through the source sensor node.

[0064] Step S205: acquiring the signal strength of each sensor node, and updating the connection status of each sensor node according to the signal strength.

[0065] Specifically, in this embodiment, the intelligent fire detection system will also detect the smoke concentration of the fire scene in real time and build a fire scene received signal strength (Received Signal Strength Indication, RSSI) model, and judge the real-time signal strength of each node based on the model, and update the network structure in real time according to the signal strength, that is, the connection status of each sensor node, and select the appropriate sensor node for connection, thereby improving the stability and response time of the Bluetooth network in fire scenarios.

[0066] For example, sensor node 1 is initially connected to sensor nodes 2, 3 and 4. When it is determined that the signal strength value of sensor node 3 is reduced due to insufficient power, the connection between sensor node 1 and sensor node 3 can be disconnected, and only the connection between sensor node 3 and sensor node 4 is retained, thereby avoiding the mistransmission of fire information due to insufficient energy of sensor node 2, thereby improving the stability of the entire network. Of course, this implementation is only an example for illustration, and does not limit the update content of the connection status of each sensor node.

[0067] In the implementation mode of the present application, by determining the forwarding delay time of each target sensor node according to the priority, and forwarding each target sensor node according to a different forwarding delay time, the risk of data packet collision is reduced, thereby improving the stability of information forwarding, and when it is determined that each target sensor node has received the fire message sent by the target sensor node with a higher priority, the source sensor node does not need to repeatedly forward it to it, thereby effectively reducing the unnecessary energy consumption of the source sensor node and improving the endurance performance of the node.
