Example 1
The intelligent fire control management system shown in fig. 1 comprises a management server, control nodes of a group and group nodes, wherein the control nodes of the group manage self-organizing network communication in the group, key relay nodes are arranged in the group nodes, and the management server stores position information of the key relay nodes. The system management server divides signal transmission information of the group control node into uplink and downlink communication channels; and transmitting a control broadcast signal by the nodes in the group control node group in the downlink channel, wherein the group nodes receive the control broadcast signal, match the preset broadcast identification information in the group nodes according to the identification signal in the control broadcast signal, read the data in the control broadcast signal when the identification information of the group is identified, otherwise maintain a dormant state, and set the control nodes at key positions or the real-time transmission of the group node monitoring information when the dormant state is reached.
Optionally, after the system is initialized, the group control node enters a waiting state, and after the management server activates the working state of the nodes in the group, the group control node enters a monitoring state, and all the current states of the nodes in the group are fed back to the management server. After receiving the information, the management server feeds back a time signal to the group node, that is, the next uplink channel information is used as the reference time fed back to the management server next time.
And when the abnormal situation is detected in the group nodes, the group nodes can be automatically awakened according to the distance rule and timely send the current state and monitoring information to the group control nodes.
Optionally, when a new node in the group is to join the group ad hoc network, a control node meeting the requirement of the communication signal strength threshold is detected, and a login message is sent to the determined control node, where the sent login message includes information such as the type of the node and the MAC address. After receiving the node login message, the control node records the type and address of the node, and sends a confirmation message to the node, wherein the confirmation message contains the network address allocated to the node.
The control nodes detect network connection and data transmission through state information among the nodes. After the optional Internet of things node is accessed to the network, a state message is sent to the control node every 10s, and the state of the control node is reported. The control node stores the current state information of each node in a buffer area for linkage awakening during inquiry and emergency communication.
And when the control node does not receive the status message sent by the node within a period of time, actively sending a status message request to the node, and if the control node does not receive the status message of the node after a period of time, recording the status of the node as having communication faults, and triggering the detection of the reasons of the communication faults. The status message includes: the detection and retransmission of the power of the communication node and the network communication state, and the like.
In an actual application scene, the actual power wiring cannot meet the requirements of the actual scene, the key nodes and the self-standby power supply are configured in the subareas, system resources can be effectively saved, detection and measurement in the group nodes can be realized by adopting the self-power supply such as battery power supply, the diversification of the application scene can be realized, wiring resources are saved, and node electric quantity information is set in fault cause detection.
The control node monitors the node information in the group, monitors the state information of the nodes, and acquires the state information in the group nodes. Optionally, the data reporting time of the equipment is monitored to judge the state information of the Internet of things equipment, namely the control node, and based on the time difference between the historical reporting time and the current time and the size relation between the historical reporting time and the preset time length threshold, whether the Internet of things equipment is in an offline state or not is judged.
If the time difference between the historical reporting time and the current time is larger than a preset time threshold, the management server updates the running state of the Internet of things equipment into an offline state, determines an offline reason based on information in the state information, and adjusts a communication rule or a maintenance strategy according to the offline reason.
Optionally, the state information includes electric quantity information data recently reported by the internet of things device, and the control node may determine an offline reason according to the electric quantity data information, and the corresponding processing may be as follows: under the condition that the last reported residual electric quantity of the first equipment is smaller than a preset electric quantity threshold value, determining that the offline cause of the first equipment is offline due to no electric quantity; and determining that the offline cause of the first device is offline due to link congestion under the condition that the last reported residual electric quantity of the first device is greater than or equal to a preset electric quantity threshold and the residual communication bandwidth flow of the first device is smaller than a preset flow threshold.
Optionally, after updating the running state of the first device to the offline state, the management server may obtain the remaining power of the first device when the data is recently reported based on the power information of the last reported state information of the first device, and then may determine the offline reason of the first device based on the remaining power of the first device and the preset power threshold. The preset power threshold may be a power consumption value of the first device that is normal in the period of the preset duration threshold, and it is understood that if the remaining power of the first device is less than the preset power threshold, after the period of the preset duration threshold, the first device is most likely to be automatically offline due to power consumption. In this way, the management server may determine that the offline cause of the first device is offline due to no power, if the last reported remaining power of the first device is less than the preset power threshold.
Optionally, if the last reported remaining power of the first device is greater than or equal to the preset power threshold, the management server may continue to determine the offline reason of the first device based on the remaining traffic situation of the first device. The management server may query the traffic situation of the first device, obtain traffic information of a normal link of the first device, and then compare whether the detected test traffic of the first device is smaller than a preset traffic threshold, where the preset traffic threshold may be a link traffic value of the first device that normally uses the data service. If the test traffic of the first device is smaller than the preset traffic threshold, the first device is indicated to be offline when the link congestion breaks the data transmission service, and the offline reason of the first device can be determined as that the link congestion or the device failure communication fault leads to offline.
Preferably, for the case that the offline cause does not belong to the no-power condition, the control node or the management server may determine the offline cause of the first device in combination with the operation state of the second device that is a preset distance threshold from the first device.
The control node obtains the running state of the second equipment which is a preset distance threshold from the first equipment; when the last reported residual electric quantity of the first equipment is larger than or equal to a preset electric quantity threshold value and a second equipment with an on-line running state exists, and the second equipment cannot relay communication with the second equipment, determining that the off-line of the first equipment is caused by equipment damage or dismantling; and determining that the offline reason of the first device is offline due to poor network signals under the condition that the last reported residual electric quantity of the first device is greater than or equal to a preset electric quantity threshold value, and meanwhile, no second device with an online running state exists and the second device with an offline running state exists.

The management server judges whether the position information (x, y) of the Internet of things node is damaged by people or not and judges whether the position is moved or not through the change of the position information (x, y) of the Internet of things node, and accordingly information setting is obtained.
Preferably, the management server repartitions the area information for the first device not reporting the information according to the change of the relative coordinate information, and sets a relay communication node for the first device.
In other embodiments, the nodes of the internet of things equipment at different positions are Zigbee wireless detectors, the wireless detectors set relevant thresholds, and the detectors timely send fire alarms and alarm information (such as temperature values and temperature thresholds; smoke refractive index, smoke refractive threshold, or CO concentration, toxic gas concentration, etc.) to a fire control center, i.e. a management server, through a wireless network. In order to save system resources, the reference node is configured as a key node, namely the key node performs real-time signal detection and reporting.

After the control node receives the data, the control node sends the temperature or smoke data to the management server one by one, and after receiving all the data, the management server sends a data transmission stopping instruction to the control node, and the control node forwards the control command to the equipment.
And when fire information is detected in the management server, the dormant linkage node is awakened for linkage control, the control node sends an awakening message to the node, the node exits from the dormant mode after receiving the awakening message, the elevator wireless terminal sends a dormant message to the node again after the fire linkage control process is completed and the alarm condition is eliminated, and the node replies a confirmation message and reenters the dormant state after receiving the message.
