As shown in Figures 1 to 4, a seismograph status monitoring system based on bluetooth beacons proposed by the present invention includes a hand-held monitoring device 1 and a node-type seismograph 2, and the hand-held monitoring device 1 is provided with a first low-power bluetooth module Group 11 and monitoring module 12, the second low-power bluetooth module 21 and the data acquisition module 22 for obtaining the state data of the node-type seismograph 2 are arranged in the node-type seismograph 2; The data acquisition module 22 and the first Two low-power consumption modules 21 are unidirectionally connected, the first low-power consumption Bluetooth module 11 and the second low-power consumption Bluetooth module 21 are signal-connected, and the first low-power consumption Bluetooth module 11 is connected to the monitoring module 12 .

The first low-power bluetooth module 11 and the second low-power bluetooth module 21 use low-power bluetooth beacons as the state information transmission carrier for the state monitoring of the node-type seismograph 2. By customizing the beacon data format, it meets Complete status data transmission needs, and use the handheld monitoring device 1 to receive Bluetooth beacons, monitor and analyze the status of large-scale node-type seismometer clusters, and provide early warning and alarms for potential abnormalities and abnormal sites.

At the same time, there are one or more handheld monitoring devices 1, and multiple node-type seismographs 2. Each handheld monitoring device 1 can be selectively connected to each node-type seismograph 2, and each handheld monitoring device 1 can monitor simultaneously. A large number of node-type seismographs 2, and multiple handheld monitoring devices 1 do not affect each other and can be used at the same time; it improves the traditional Bluetooth solution that needs to establish a point-to-point Bluetooth connection between node-type seismographs and handheld monitoring devices. A hand-held monitoring device can only monitor the state of one or a few node-type seismometers at the same time, which is difficult to be used in large-scale seismic exploration.

In addition, the use of custom Bluetooth beacon transmission also solves the inconvenient defect that a WiFi router needs to be deployed during the use of the traditional WiFi solution. And the defect that the 4G cellular network solution can only be used in areas with 4G signals.

The use of connectionless low-frequency low-power Bluetooth broadcast beacons as a means of status information transmission can reduce the extra energy consumption generated by the status monitoring function, avoid the power waste caused by high-frequency communication and long-term wake-up of the communication module, and greatly improve the performance of nodes. The field endurance of the type seismometer.

The second low-power Bluetooth module 21 sends a Bluetooth broadcast beacon to the first low-power Bluetooth module 11 in the form of a broadcast, so that the first low-power Bluetooth modules 11 in multiple handheld monitoring devices 1 can simultaneously receive Thanks to the Bluetooth broadcast beacon, multiple handheld monitoring devices 1 can work independently of each other, and each handheld monitoring device 1 can simultaneously monitor the status of multiple node-type seismometers 2 . This makes it possible for multiple people to monitor the equipment at the same time without interfering with each other when the deployment range of the node-type seismometer is extremely large in the actual operation process.

Before the scan request packet fed back by the first low-power bluetooth module 11, the monitoring module 12 calls the first low-power bluetooth module 11 to obtain the bluetooth beacon load; the monitoring module judges whether the bluetooth beacon load is a node Type seismograph 2 sends out; If so, then the first low-power bluetooth module 11 sends a scan request to the second low-power bluetooth module 21, and the second low-power bluetooth module 21 is after receiving the scan request packet , send a scan response data packet to the first low-power Bluetooth module 11; if not, ignore the Bluetooth beacon load, and do not respond.

S3: The second Bluetooth low energy module 21 sends a scanning response data packet to the first low energy Bluetooth module 11, and the scanning response data packet carries the status data of the node-type seismograph 2 .

After the second low-power bluetooth module 21 sends the scan response data packet to the first low-power bluetooth module 11, after the handheld monitoring device 1 processes the scan response data packet, it exports the scan log to other devices 3, specifically including Follow the steps below:

The monitoring module 12 calls the first low-power bluetooth module 11 to obtain a scan response packet;

After the node-type seismograph 2 is powered on, the second low-power bluetooth module 21 enters the dormant state after initialization is completed, so as to further reduce energy consumption. The second low-power bluetooth module 21 can be controlled by its own timer and the main control chip. wakeup source. If the wake-up source of a certain wake-up is the main control chip, the second low-power bluetooth module 21 will receive the latest status data from the data acquisition module 22, and send the data to one or more handheld monitors in the form of broadcast In the first low-power bluetooth module 11 of the device 1, the monitoring module 12 transfers the data to be processed and sent to other devices to update the scan log in other devices. If abnormal sites in the scan log are found, the The abnormal site is processed, and then the operating status of the seismograph can be reconfirmed using the handheld monitoring device 1 .

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, any person familiar with the technical field within the technical scope disclosed in the present invention, according to the technical solution of the present invention Any equivalent replacement or change of the inventive concepts thereof shall fall within the protection scope of the present invention.
