Fig. 1 shows a block diagram of a low-power bidirectional triggering multi-network converged ground disaster monitoring system according to an embodiment of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a low-power consumption bidirectional triggering multi-network converged ground disaster monitoring system, where the system includes:
a plurality of detection devices 10 for detecting data reflecting a ground disaster state, wherein each detection device is provided with a Lora module;
among them, the plurality of detection apparatuses 10 perform data detection as a plurality of terminal nodes on the terminal side. By way of example, the detection device 10 may be a sensor of various types, by means of which the required data can be acquired.
And the wireless gateway 12 is configured to collect data of each detection device 10 according to a predetermined period through the Lora network, and report the collected data to the network platform 14 through the remote network in a network connection state.
Wherein the remote network may be determined based on actual network conditions at the site. For example, a 4G or NB mode may be used, and the modules (4G/NB modules) may be selected based on the actual network conditions at the site by standardizing the interfaces. Software configuration can be carried out after the modules are connected, long connection is adopted in a communication mode, and a plurality of network platforms can be connected at the same time. For the Lora short-distance wireless transmission networking mode, the transmission within 2km is realized under the shielding condition, and the transmission within 5km is realized under the communication condition.
That is, the data can be collected by the wireless gateway at regular time and reported to the network platform.
According to the technical scheme, the data reflecting the ground disaster state can be detected by using the plurality of detection devices, then the wireless gateway can acquire the data of each detection device according to a preset period through the Lora network, and report the acquired data to the network platform through the remote network under the condition of being in the network connection state. Therefore, short-distance wireless mode networking (Lora wireless networking) can be adopted for a ground disaster monitoring area without network signals, data are transmitted to a network signal position (a gateway of short-distance wireless transmission), and then the data are transmitted to a network platform through a remote communication mode (namely, a multi-network fusion mode combining short-distance wireless transmission and remote communication), so that the problems of poor network signals, large power consumption of Beidou equipment, limited transmission and the like can be solved.
According to an embodiment of the present invention, the detecting device 10 is further configured to compare the detected data with a corresponding preset trigger threshold, and send the detected data to the wireless gateway 12 if the detected data is greater than the corresponding preset trigger threshold;
the wireless gateway 12 is further configured to compare the received data greater than the corresponding preset trigger threshold with a preset alarm threshold, and report the received data greater than the corresponding preset trigger threshold to the network platform 14 when the received data greater than the corresponding preset trigger threshold is greater than the preset alarm threshold.
That is, while the above-mentioned working mode of timed reporting is performed, a working mode of triggering reporting in real time may also be performed (that is, each detection device has a triggering function, and when triggering occurs, triggering alarm data is sent to the wireless gateway). Therefore, under the condition of geological disasters, the geological disasters can be reported to the network platform quickly, so that the network platform side can take corresponding measures in time to deal with the geological disasters.
According to an embodiment of the present invention, the wireless gateway 12 is further configured to receive a detection device configuration command sent by the network platform 14, determine whether the command is a valid command, and execute parameter configuration for the corresponding detection device 10 if the command is a valid command.
Therefore, the network platform can be used for receiving, processing and displaying data, and can also perform the functions of reading, configuring and remotely upgrading parameters to the wireless gateway in real time.
According to an embodiment of the present invention, the command includes an identifier and configuration parameters of the detection device to be configured, and the determining, by the wireless gateway, whether the command is a valid command includes:
comparing the identification of the detection device to be configured with the identification in the preset identification library, and comparing the configuration parameter with the preset parameter range;
judging the command to be an effective command under the condition that the identifier of the detection device to be configured is matched with the identifier in the preset identifier library and the configuration parameter is within the preset parameter range;
and judging the command to be an invalid command under the condition that the identifier of the detection device to be configured is not matched with the identifier in the preset identifier library and/or the configuration parameter exceeds the preset parameter range.
For valid commands, the wireless gateway may perform parameter configuration operations on the sensors according to the valid commands, and for invalid commands, discard directly.
According to an embodiment of the present invention, the detection apparatus 10 and the wireless gateway 12 are in a sleep state without data transmission and are awakened into an active state when there is data transmission.
That is, the system enters a low power consumption state when no data is transmitted, and jumps out of the low power consumption state when data is transmitted or network platform data is received (both the wireless gateway and the sensor terminal node have a sleep-wake function). The wireless gateway and the sensor terminal node adopt a low-power-consumption design concept, the sensor terminal node can continuously work for 3 years under the condition of no charging, and the wireless gateway can continuously work for 1 month under the condition of no charging.
For example, the wireless gateway and the sensor terminal node may jump out of the low power consumption state when the wireless gateway reaches a predetermined period of timed data reporting, when the sensor terminal node data triggers, and when the network platform sends a command.
Furthermore, when the wireless gateway is in the dormant state under the condition of no data transmission, whether data transmission exists or not can be regularly monitored in the dormant state, whether the data are the related data of the node or the related data of the wireless gateway can be judged after the data are received, if yes, corresponding processing is carried out and a processing result is returned, and if not, the wireless gateway continues to enter the dormant state.
Therefore, the received data can enter the working state under the condition that the received data is determined not to be irrelevant data, the irrelevant data is prevented from being awakened by mistake, and unnecessary power consumption is avoided.
According to one embodiment of the invention, the wireless gateway 12 may include a memory for storing data detected by the detection device and configuration parameters sent by the network platform. The data detected by the detection device comprises transmitted data and unsent data, and for the storage of the unsent data, the wireless gateway can be convenient to resend again to ensure that the data is successfully transmitted.
In addition, in order to guarantee the reliability of data, both short-distance wireless transmission and long-distance data transmission have an acknowledgement mechanism and a retransmission mechanism. The wireless gateway also has a data automatic reissue mechanism. The specific implementation process may adopt a method existing in the prior art, and is not described herein again.
