DETAILED DESCRIPTION

[0024] Embodiment 1: The device adopts a track 1 type mobile structure, and deploys a mobile device 3 that can move on the track 1 on the track 1, wherein the track 1 can adopt a monorail, and the track 1 is completely deployed in the construction range that needs to be monitored. The track 1 is placed in the air and can be supported above the construction range by support rods. A power device 32 is provided on the mobile structure itself, and the power device 32 can be remotely controlled to start. The power device 32 allows the entire mobile device 3 to move arbitrarily on the track 1. The start of the power device 32 depends on the power supply, and the mobile device 3 is often not used all the time. For example, it can be used periodically. When its power is exhausted or idle, it can be controlled to enter the storage box 2 at the end of the track 1 for power supply.

[0025] like Figure 1 and Figure 2 As shown, the storage box 2 is also provided with a maintenance seat 21, which is used as a door of the box in daily state and is buckled into the side of the box. When maintenance is needed, the maintenance personnel climb up the side of the storage box 2 through the ladder 22 provided under the maintenance seat 21, and then open the maintenance seat 21, so that the maintenance seat 21 is in a horizontal state, so that the maintenance personnel can lean on or sit on the maintenance seat 21, or some maintenance tools can be placed on the maintenance seat 21.

[0026] In addition, a power storage component 26, as well as a solar power supply component 23 and a wind power supply component 24 connected to the power storage component 26 are also provided inside the storage box 2, wherein the solar power supply component 23 and the wind power supply component 24 are both located above the storage box 2, and are used to convert solar energy and wind energy into electrical energy, and transport it to the power storage component 26 for storage through components such as an inverter, and are used to replenish and supply electrical energy to the mobile device 3 when the power in the mobile device 3 is exhausted. The power supply method adopts contact power supply, and the contact power supply is realized by relying on corresponding metal contact points arranged on the mobile device 3 and the power storage component 26.

[0027] The alarm device 25 is arranged on the storage box 2. The alarm device 25 has an unlimited transmission function and a built-in Internet of Things module. It can transmit the data of abnormal conditions to the terminal device of the manager through remote transmission for prompting. The same alarm device 25 can also have a local alarm function. For example, the alarm device 25 is equipped with a sound and light alarm to remind and alarm the surrounding people.

[0028] Embodiment 2: Based on Example 1, the mobile device 3 includes the power device 32 and the mobile frame 31 mentioned above, wherein the mobile frame 31 serves as a carrier, the power device 32 is arranged on the mobile frame 31, and a plurality of mobile wheels 33 are arranged in the mobile frame 31, all of which are clamped on the side wall of the track 1, and at least one mobile wheel 33 is transmission-connected to the power device 32, so that the mobile wheel 33 can rotate on the track 1, thereby achieving the effect of moving the mobile device 3 on the track 1. In addition, a rotary encoder 5 is also connected to the mobile wheel 33, and the rotary encoder 5 is used to obtain the data of the rotation of the mobile wheel 33. By obtaining the number of rotations of the mobile wheel 33, it is possible to know how far the overall mobile device 3 has moved and what position it is in.

[0029] It should be noted that if the overall mobile device 3 moves far, the Beidou GPS positioning device can be used to replace the rotary encoder 5. Therefore, the device realizes the mobile function of reaching any position on the track 1 through the power device and the moving wheel 33, so that the construction site at a far distance can be quickly checked without the need for actual maintenance personnel to visit, and there is no need to deploy a large number of sensors and cameras.

[0030] In addition, a base 34 is provided at the lower half of the mobile device 3, a sliding frame 35 is provided at the bottom end of the base 34, and a data acquisition device 7 is provided below the sliding frame 35 (not directly connected to the slide, but connected to the bottom of the sliding frame 35 through a reversing wheel 37). The data acquisition device 7 is integrated with a camera, a lighting device, and a total station device. The base 34 is fixedly arranged, and the sliding frame 35 can slide on the base 34, so that the data acquisition device 7 can be moved to both sides of the track 1, and can acquire construction data of the target area in different directions.

[0031] Embodiment 3: like Figure 5 As shown, the steering of the data acquisition device 7 depends on the rotation of the reversing wheel 37. There are two reversing wheels 37. At least one reversing wheel 37 is connected to a motor, which can drive the reversing wheel 37 to rotate. After the reversing wheel 37 rotates, it synchronously drives the data acquisition device 7 fixed on the reversing wheel 37 to rotate synchronously. Under the action of the mutual contact and limitation between the reversing wheel 37 and the limit bar 36, the data acquisition device 7 can be moved to both sides of the track 1 instead of being located below the track 1 (being located below the track 1 will overlap with the dust removal water mist spraying range disclosed later, and the water mist spraying area will affect data acquisition), thereby monitoring the construction site on one side or the other side of the track 1.

[0032] It should be noted that the acquisition targets of the mobile acquisition device include but are not limited to facial data of people in the target area, construction scope size, construction status, maintenance status of the use area, and edge monitoring of the foundation pit slope.

[0033] Embodiment 4: The device also integrates a dust removal function, and the dust removal is achieved by dropping water mist from high altitude. Specifically, the storage box 2 of the device is also provided with a dust removal component 4, including a water tank 41, the water tank 41 has a built-in water pump, and the water tank 41 is connected to a water supply pipe 42, and the main part of the water supply pipe 42 is located below the track 1, so that with the help of the setting of the track 1, a large area of ​​the construction area can be covered simply by the setting of the water supply pipe 42, so as to achieve the ability to remove dust from the entire construction area.

[0034] In order to further realize the water-saving function and make the spraying position of the water supply pipe 42 controllable, a large number of dust removal nozzles 6 (including nozzles 63) connected to the water supply pipe 42 are also arranged below the water supply pipe 42. Each dust removal nozzle 6 is provided with an independent sliding switch 61 for controlling the start and stop of the nozzle (sliding up and down, so that construction personnel can turn on the control nozzle at a designated position for the area where dust removal is required).

[0035] Due to the large number of the above-mentioned nozzles, it is rather cumbersome to control the opening and closing of the nozzles in batches, and the degree of automation is low. Therefore, the device further provides a steering wheel 62 and a permanent magnet block 64 on the dust removal nozzle 6, and further provides a side panel 341, a drive bar 342, an electromagnetic device 343 and a cross beam 344 on the base 34.

[0036] Specifically, if Figure 5 As shown, the steering wheel 62 is horizontally arranged, and the permanent magnet block 64 is fixedly arranged at the bottom end of the dust removal nozzle 6. In the specific implementation process, the mobile device 3 moves above the track 1 to monitor the surrounding construction environment, and adjusts the direction of the dust removal nozzle 6 when necessary.

[0037] like Figure 8 As shown, by controlling the start of the electromagnetic device 343, the two side plates 341 and the two cross beams 344 are pushed to move in the horizontal direction by the magnetic force, and at the same time, the driving bar 342 (which can be a rack) located on the side plate 341 moves closer to or away from the steering wheel 62 (as shown in FIG. Figure 6 As shown), it contacts the steering wheel 62, and as the moving device 3 moves, the steering wheel 62 rotates, thereby changing the spray direction of the dust removal nozzle 6 from one side to the other opposite side. If the nozzles need to be opened or closed in batches, they can be started by controlling the magnetic control device 8. The current direction in the magnetic control device 8 generates an attraction or repulsion on the permanent magnet block 64 under the dust removal nozzle 6, thereby controlling the passing dust removal nozzle 6, so that the dust removal nozzle 6 can achieve the corresponding switching of the open or closed state through the sliding switch 61.

[0038] It should be noted that in order to further accurately control the mobile device 3's control over the dust removal nozzle 6 it passes through, such as accurately controlling the start and / or steering of the nozzle in the distance interval of 50-100 meters from the starting point, this function can be achieved through the rotary encoder 5 integrated with the Beidou GPS positioning device, so that the mobile device 3 only starts the magnetic control device 8 and / or the electromagnetic device 343 when it moves to the target area to control the steering and switching function of the dust removal nozzle 6. This device should also establish a database locally or in the cloud, which is used to store the data historically acquired by the data acquisition device 7, such as the facial data of registered personnel, or edge wave construction and maintenance data. If the construction data or personnel acquired during the construction process are inconsistent with those stored in the database, an alarm will be processed.

[0039] Specifically, the function of slope monitoring is to use the mobile device 3 to compare the data of the foundation pit edge, taking the edge of the foundation pit as the reference, and to perform alarm processing after displacement of the foundation pit slope occurs.
