Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of monitoring equipment, in particular to an engineering ground subsidence monitoring mechanism. Background Art
[0002] After the construction of roads, houses, tunnels, bridges, etc. (hereinafter collectively referred to as projects for the sake of convenience), there is a need to monitor the settlement data of the project ground after construction (such as the road surface of the road, the ground of the tunnel, the ground or top of the building, the bridge deck, etc.) to prevent adverse effects on the safety of the project when settlement occurs in the corresponding area.
[0003] In the prior art, the detection of whether the ground of a relevant project has settled generally includes the following methods. (1) Elevation observation method: Set up elevation points at the relevant ground monitoring positions of the relevant projects, and regularly measure the changes in the heights of the elevation points and reference points to reflect the changing trend of the settlement. (2) Precision leveling observation method: Set up leveling points at the relevant ground monitoring positions of the relevant projects, and regularly conduct leveling measurements to reflect the changing trend of the settlement in the monitoring area. (3) Electronic leveling observation method: Set up electronic level monitoring points at the relevant ground monitoring positions of the relevant projects, and use electronic levels to conduct leveling measurements. Compared with the precision leveling observation method, it has the advantages of high measurement accuracy and easy operation. Although the above-mentioned monitoring methods have met the actual monitoring needs to a certain extent, due to structural limitations, there are still the following shortcomings that need to be improved. Specifically, staff are required to go to the site to check the monitoring data, and then manually judge whether subsidence has occurred at the relevant locations of the project. The above mode will bring inconvenience to the monitoring personnel, and when the monitoring personnel's skill level is not good, there is a chance of misjudging the data. More importantly, when the monitoring personnel themselves do not go to the site to check the data, if ground subsidence occurs and is not handled in time, there is a chance of the accident expanding (for example, ground subsidence around constructed houses, relevant personnel are unaware and fail to evacuate people in time, and subsequent building collapses, etc., cause personal injury).

[0015] Figure 1 , 2As shown, the laser distance measuring module A1 and the laser irradiation pen A3 (a high-power laser pen flashlight of model OBS-5952, with a direct irradiation distance of 2 kilometers) are in a horizontal structure, and the emitting heads of the laser distance measuring module A1 and the laser irradiation pen A3 are in a face-to-face structure. The outer diameters of the movable rod 4 and the movable rod A8 are respectively smaller than the inner diameters of the support tube 3 and the support tube A7. The prompt circuit includes a resistor R1, an adjustable resistor RP1, a transistor Q1, and an alarm B1 connected via circuit board wiring. One end of the resistor R1 is connected to one end of the adjustable resistor RP1 and the base of the transistor Q1. The collector of the transistor Q1 is connected to the negative power input terminal of the alarm B1. The other end of the adjustable resistor RP1 is connected to the emitter of the transistor Q1. The two poles of the battery G1 and the two ends of the charging socket CZ1 are connected by wires (the plug of the external power charger is inserted into the socket of the charging socket CZ1, which can charge the battery G1), and are connected in series with the power input terminals 1 and 2 of the SMS module A2, the positive power input terminal of the power input terminal of the prompt circuit, the positive power input terminal of the buzzer B1 and the emitter of the transistor Q1, and the power input terminals 1 and 2 of the laser ranging module A1 through wires, and the signal output terminal 3 of the laser ranging module A1 and the other end of the resistor R1 at the signal input terminal of the prompt circuit are connected by wires.

[0016] Figure 1 , 2As shown, before using the new type, the transmitting device and the receiving device are placed at the monitoring point and the reference point (areas where the interval monitoring point is not prone to settlement), and the two are separated by a certain distance. After two staff members turn on the power switch S1 and the power switch AS2 respectively, the power input end of the SMS module A2, the prompt circuit, the laser ranging module A1 and the laser irradiation pen A3 are powered. The two staff members cooperate to loosen the bolt 5 and the bolt A10 respectively, and then adjust the positions of the movable rod 4 and the movable rod A8 in the circumferential direction or the up and down direction, so that the laser irradiation pen A3 is powered and the light spot emitted is irradiated on the front middle part of the indicator plate 6 (at this moment, one of the staff members tightens the bolt 5 and prompts the other staff member to tighten the bolt A10), that is, at this moment, the laser beam emitted by the laser ranging module A1 emitter head is irradiated on the front middle part of the baffle 11. After the laser beam emitted by the laser ranging module A1 is irradiated on the front end of the baffle, the longer the interval, the higher the voltage signal output by the 3rd pin of the laser ranging module A1, and the closer the interval, the lower the voltage signal output by the 3rd pin of the laser ranging module A1.

The voltage signal is divided by resistor R1 and adjustable resistor RP1, and enters the base of transistor Q1 with a voltage higher than 0.7V. The transistor Q1 will turn on the collector to output a low level and enter the negative power input terminal of the buzzer B and the signal input terminal pin 3 of the SMS module A2, so that the buzzer B is powered and sounds to prompt the on-site staff; after the pin 3 of the SMS module A2 inputs a low level, the SMS module A2 will send out the first set of internally stored SMS messages, and the relevant remote personnel will be able to understand the specific situation at the first time after receiving the SMS messages.
[0017] Figure 1 , 2As shown above, when ground subsidence occurs at any position of the monitoring point or the reference point during operation, the alarm will promptly sound an alert on site to remind the nearest staff to find out the cause of the subsidence in time, and can also remind the relevant management personnel who are not on site by text message to prevent the relevant personnel from being unaware of the ground subsidence and failing to deal with the emergency in time, which may cause safety hazards (for example, if the ground around a built house subsides, the relevant personnel can evacuate people in time and reduce the chance of personal injury caused by subsequent building collapse). The battery G1 and the battery AG2 are lithium batteries of model 12V / 5Ah; the resistance value of the resistor R1 is 6K; the transistor Q1 is an NPN transistor of model 9013; the buzzer B1 is a finished active continuous sound alarm of model XQ12V; the resistance value of the adjustable resistor RP1 is 47K (adjusted to 1K in this embodiment, the handle of the adjustable resistor RP1 is located outside the upper end of the fixed seat, and the staff adjusts the resistance value of the adjustable resistor RP1 to a larger value, and the greater the partial pressure, then in actual application, the farther the distance between the detection head and the baffle of the laser ranging module A1 is, the buzzer B and the like will be powered to work, that is, the detection distance becomes farther, and the staff adjusts the resistance value of the adjustable resistor RP1 to a smaller value, and the partial pressure is smaller, then in actual application, the closer the distance between the detection head and the baffle of the laser ranging module A1 is, the buzzer B and the like will be powered to work, that is, the detection distance becomes closer. , the specific use staff adjusts the setting according to the spacing between the on-site monitoring points and the reference points); the laser ranging module A1 is a finished laser ranging sensor of model KLH-03T-20hz, which has two power input terminals and a signal output terminal. When working, the signal output terminal will output an analog voltage signal that dynamically changes between 0-10V according to the different detected spacings; the SMS module A2 is a SMS alarm module of model GSM800. The finished SMS alarm module has two power input terminals 1 and 2, and signal input ports 3-8. After a low-level signal is input to each signal input port, the finished SMS alarm module will send a text message via the wireless mobile network. The SMS alarm module stores text messages.
