Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering, and particularly relates to an alarm device. Background Art

[0002] Highway maintenance construction warning fences are of great significance during the maintenance construction process. They can warn passing vehicles and unauthorized personnel from entering the maintenance construction area, alleviate the impact caused by vehicles breaking into the construction area, and ensure the life and property safety of the maintenance construction team.

[0003] Common highway maintenance construction warning fences usually use infrared alarm devices to monitor whether vehicles break into the construction area and then send alarms through mobile phone messages. Infrared alarm devices have the following disadvantages:

[0004] (1) Infrared alarm devices are vulnerable to interference. Infrared alarm devices monitor whether vehicles enter the construction area through infrared rays. However, during the construction process, infrared alarm devices are usually exposed to direct sunlight and the ground with high temperature, so the infrared itself will be interfered and the device will fail.

[0005] (2) The cost of infrared alarm devices is relatively high. When infrared alarm devices are used for highway maintenance construction, since they need to monitor vehicles with relatively high driving speeds, the infrared rays need to have high performance to be able to monitor oncoming vehicles at a relatively far position. And the cost of infrared rays with high performance is relatively high.

[0006] (3) The installation position of infrared alarm devices is restricted greatly. Due to the vulnerability of infrared alarm devices to interference, the installation position needs to be carefully considered during use to reduce interference as much as possible and the possibility of false alarms. Since the installation position needs to be carefully considered, in some cases, the device cannot be installed at the required position, making it difficult for infrared alarm devices to exert their functions.

[0007] (4) The alarm effect of infrared alarm devices is not good. Infrared alarm devices use mobile phone messages to send alarms. However, when maintenance construction personnel are performing construction operations, they are very likely to ignore the mobile phone messages, resulting in untimely receipt of alarm messages and the inability of construction personnel to take timely evasive actions, leading to safety accidents of casualties. Content of the Utility Model

[0008] Aiming at the above technical problems existing in the prior art, the utility model provides a visual alarm device that can be applied to highway maintenance construction. The purpose is to be able to place the alarm device on the highway cones so as to monitor whether there are vehicles entering the construction area on the highway through a camera and issue a warning in time, enabling construction personnel to take timely evasive actions and avoid accidents of casualties to ensure the safety of construction personnel.

[0009] To achieve the above object, the specific solution of the present utility model is as follows:

[0010] An alarm device, characterized in that it includes a barrel sleeve body, a camera, a Bluetooth speaker, a control unit and a power supply. The camera and the Bluetooth speaker are respectively installed on both sides of the barrel sleeve body. On one side inside the barrel sleeve body, there is a device placement chamber. The camera and the Bluetooth speaker are respectively connected to the control unit, and the control unit is installed in the device placement chamber. The power supply provides the working voltage for the camera, the Bluetooth speaker and the control unit respectively.

[0011] Furthermore, the barrel sleeve body includes an annular column body, a camera loading box and a speaker loading box. The camera loading box and the speaker loading box are respectively installed on both sides of the annular column body. The camera is arranged on the camera loading box, and the Bluetooth speaker is arranged on the speaker loading box.

[0012] Furthermore, the control unit includes a control chip, a LoRa module and a Bluetooth module. The control chip is respectively connected to the Bluetooth module and the LoRa module. The Bluetooth module is connected to the Bluetooth speaker. The LoRa module is installed on the top of the barrel sleeve body. The LoRa module is used to connect to terminal devices, and the terminal devices include mobile phones, computers, laptops and iPads.

[0013] Advantages of the present utility model

[0014] (1) The alarm device of the present utility model is used in the highway construction area to provide visual monitoring and alarm functions. It monitors whether there are vehicles entering the construction area on the highway through the camera and issues a warning in time, enabling construction workers to take evasive action in time and avoiding accidents of casualties to ensure the safety of construction workers.

[0015] (2) The structure of the alarm device of the present utility model is simple and the cost is low. It mainly monitors through the camera and alarms through the Bluetooth speaker. The alarm message has real-time performance and can alarm construction workers to take evasive action in time. The procurement costs of both are low, and both can complete the monitoring task.

[0016] (3) The position limitation of the alarm device of the present utility model is small. Because it is not easily interfered, construction workers only need to aim the camera at the oncoming vehicle direction, without considering other placement limitation factors.
