Description

Technical Field

[0001] This utility model relates to the field of low-voltage control technology, and more specifically, to an intelligent low-voltage control device. Background Technology

[0002] In outdoor work projects such as geological exploration, it is often necessary to set up cameras around the exploration site to effectively monitor and manage the area around the work site; the image signals collected by these cameras need to be transmitted to a centralized screen center so that staff can view and analyze them.

[0003] In the field, satellite signals are often weak, and these cameras typically rely on their own Wi-Fi modules for signal transmission. As the distance between the camera and the receiving device increases, the Wi-Fi signal weakens. If the camera is placed too far away, the signal strength becomes insufficient to maintain stable data transmission, leading to stuttering in the captured images, and in severe cases, even disconnection, making monitoring impossible. Conversely, placing the camera too close reduces its monitoring area. Even more challenging is the difficulty in accurately judging the distance between the camera and the receiving device in the field, thus hindering proper camera placement.

[0004] In summary, there is an urgent need for a new intelligent low-voltage control device that can quickly determine the distance between the camera and the receiving device, assisting staff in rapidly deploying cameras. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model proposes an intelligent low-voltage control device.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] An intelligent low-voltage control device includes a display and multiple cameras, each equipped with an infrared rangefinder; the infrared rangefinder is used to measure the distance between the display and the corresponding camera.

[0008] By accurately measuring the distance between the camera and the monitor, staff can anticipate the approximate attenuation of the WiFi signal. Based on the distance and signal attenuation patterns, they can adjust the camera's position accordingly. This prevents the camera from being placed too close, resulting in a smaller monitoring area and incomplete coverage of the surrounding work area. It also avoids placing the camera too far away in pursuit of a large monitoring range, which could lead to signal problems, image lag, or disconnections, thus ensuring the smooth operation of the monitoring work.

[0009] Preferably, the display includes a screen body and a control cabinet. A reflective ring is provided on the upper surface of the screen body, and a reflective strip is provided on the outer wall of the reflective ring. The reflective strip is made of a highly reflective film.

[0010] The reflective strip design significantly enhances the reflection of infrared light. Compared to ordinary display surfaces, the reflective strip can reflect infrared light back to the infrared rangefinder more concentratedly and efficiently, reducing scattering and energy loss during reflection. This results in a clearer and stronger reflected signal received by the infrared rangefinder, thus greatly improving the accuracy of distance measurement. This is crucial for outdoor work projects such as geological exploration, which require precise camera placement to ensure effective monitoring. It helps personnel adjust camera positions based on more accurate distance data, ensuring the stability and effectiveness of the monitoring system.

[0011] Preferably, an electric telescopic rod is provided on the lower end face of the reflective ring, which can drive the reflective ring to move up and down.

[0012] The outdoor environment is complex, and various obstacles, such as trees and rocks, may interfere with the propagation and reflection of infrared light. When the infrared propagation path is partially blocked, adjusting the height of the reflective ring can change the reflection angle of the infrared light, avoiding obstructions and allowing the reflected signal to return smoothly to the infrared rangefinder. This effectively enhances the device's anti-interference capability under obstructed conditions, ensures the accuracy of distance measurement, further guarantees the smooth operation of camera deployment, and reduces measurement errors and layout issues caused by signal interference.

[0013] Preferably, the upper surface of the screen body is provided with a mounting groove, and the electric telescopic rod is set in the mounting groove. When the electric telescopic rod is fully retracted, the reflective ring retracts into the mounting groove, and the upper surface of the reflective ring is flush with the upper surface of the screen body.

[0014] The reflective ring is designed to retract into the mounting slot, effectively protecting it from environmental damage. In outdoor work scenarios such as geological exploration, the equipment may encounter collisions, dust, rain, and other hazards. When the reflective ring retracts into the mounting slot, the slot provides protection, reducing the risk of damage from impacts. It also prevents dust and rain from eroding the reflective ring and its reflective strip, extending its lifespan and ensuring the long-term stable operation of the infrared ranging function. When the reflective ring retracts into the mounting slot and is flush with the top surface of the screen, the overall appearance of the display is flat and simple.

[0015] Preferably, the reflective strip has concave reflective grooves evenly distributed on it.

[0016] The unique geometry of the concave reflective grooves converges and directionally reflects infrared light. Each groove acts like a tiny mirror, focusing and reflecting incident infrared light at a specific angle, causing the reflected light to return more concentratedly towards the infrared rangefinder. Because the concave reflective grooves are evenly distributed across the reflective band, the entire band comprehensively and efficiently reflects the received infrared light back to the rangefinder, ensuring that the rangefinder receives a clear and stable reflected signal, thereby accurately calculating the distance between the camera and the display.

[0017] Preferably, it also includes a mounting rod that can be inserted into the ground, with a threaded hole on the lower end face of the camera, and an external thread on the outer side wall of the mounting rod near the upper end that matches the threaded hole.

[0018] In field geological exploration and other similar work scenarios, when a camera needs to be installed, the first step is to insert the mounting rod into the ground. Since the lower end of the camera has a threaded hole, and the outer wall of the mounting rod near the upper end has a matching external thread, workers simply align the camera with the upper end of the mounting rod and rotate it to gradually tighten and secure the camera to the rod using the threaded connection. This installation method is simple, convenient, and allows for quick camera installation.

[0019] Preferably, the lower end of the mounting rod is provided with a tapered head.

[0020] The tapered head at the lower end of the mounting rod serves as a guide and breaks the soil. When the mounting rod contacts the ground, the tip of the tapered head makes initial contact. As pressure increases on the mounting rod, the tapered head, with its sharp shape, concentrates the pressure over a small area, generating greater pressure and making it easier to cut into the ground. As the mounting rod continues to press down, the tapered head gradually penetrates deeper into the ground. Loose soil or other geological materials are squeezed outwards along the slope of the tapered head, creating space for further insertion of the mounting rod, allowing it to be inserted into the ground more smoothly.

[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0029] Example

[0030] In this embodiment, the intelligent low-voltage control device mainly consists of a display and multiple cameras.

[0031] like Figure 1 and Figure 2 As shown, each camera 120 is equipped with an infrared rangefinder 130 for measuring the distance between the camera 120 and the display 110. The lower end face of the camera 120 is provided with a threaded hole 1201; it is also equipped with a mounting rod 170 that can be inserted into the ground. The lower end of the mounting rod 170 is a tapered head 1701, and the outer side wall near the upper end is provided with an external thread that matches the threaded hole 1201 on the lower end face of the camera 120.

[0032] like Figures 3-5 As shown, the display 110 includes a screen body 1101 and a control cabinet 1102. A reflective ring 140 is provided on the upper surface of the screen body 1101. A reflective strip 1401 made of a high-reflectivity reflective film is attached to the outer wall of the reflective ring 140, and concave reflective grooves 1402 are evenly distributed on the reflective strip 1401. An electric telescopic rod 150 is connected to the lower surface of the reflective ring 140, and the electric telescopic rod 150 is set in a mounting groove 1103 pre-cut on the upper surface of the screen body 1101. When the electric telescopic rod 150 is fully retracted, the reflective ring 140 can retract into the mounting groove 1103, at which time the upper surface of the reflective ring 140 is flush with the upper surface of the screen body 1101.

[0033] Its specific operating principle is as follows:

[0034] In actual use, the monitor 110 is placed in the appropriate position, and the operator moves the camera 120 away from the monitor 110. During this movement, the infrared rangefinder 130 emits infrared rays, which are directed towards the reflective ring 140 on the main screen 1101 of the monitor 110. Because the reflective strip 1401 has high reflectivity, and the evenly distributed concave reflective grooves 1402 on it have a converging and directional reflection effect on the infrared rays, the infrared rays are efficiently reflected back to the infrared rangefinder 130. The infrared rangefinder 130 calculates the distance between the camera 120 and the monitor 110 based on parameters such as the time it takes to receive the reflected infrared rays. The camera 120 has a built-in WIFI module and connects to the control cabinet 1102 of the monitor 110 via WIFI signal.

[0035] Once the staff obtains this distance data, they can make reasonable adjustments to the distance between the camera 120 and the monitor 110, so that the camera 120 and the monitor 110 can be stably connected via WIFI signal. On this basis, they can maximize the distance between the camera 120 and the monitor 110, thereby increasing their monitoring area.

[0036] In the field, if the propagation path of infrared rays is partially blocked by obstacles such as trees and rocks, the electric telescopic rod 150 can be controlled to move the reflective ring 140 up and down, changing the reflection angle of the infrared rays, thereby avoiding the obstruction and ensuring that the reflected signal can return smoothly to the infrared rangefinder 130, thus achieving accurate distance measurement.

[0037] When installing the camera 120, the conical head 1701 at the lower end of the mounting rod 170 is first inserted into the ground. The sharp shape of the conical head 1701 allows it to concentrate the applied pressure on a small area upon contact with the ground, generating greater pressure and facilitating penetration. As the mounting rod 170 is pressed down, soil and other geological materials are squeezed along the inclined surface of the conical head 1701, allowing the mounting rod 170 to be smoothly inserted into the ground. Afterward, the operator aligns the camera 120 with the upper end of the mounting rod 170 and, by rotating the camera 120, securely fixes it to the mounting rod 170 using the threaded connection.

[0038] By cooperating with the infrared rangefinder 130 and the specially designed reflective ring 140, reflective strip 1401, and concave reflective groove 1402 on the display 110, the distance between the camera 120 and the display 110 is accurately measured. This allows staff to anticipate the approximate attenuation of the WiFi signal and adjust the position of the camera 120 accordingly. This avoids the problem of the monitoring area being too small due to the camera 120 being set too close, thus failing to fully cover the surrounding work area of ​​the exploration site. It also prevents signal problems caused by setting the camera too far away, resulting in image lag or disconnection, effectively ensuring the normal operation of the monitoring work.

[0039] The design of the reflective ring 140, whose height can be adjusted via the electric telescopic rod 150, greatly enhances the device's anti-interference capability in complex field environments. When the infrared propagation path is blocked, it can promptly change the reflection angle to ensure the accuracy of distance measurement, further ensuring the smooth operation of the camera 120 layout and reducing measurement errors and layout issues caused by signal interference.

[0040] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
