Tower Crane High Voltage Anti-collision Alarm

I. Overview With the rapid development of electric power, it is closely related to people's life and work, and people even need to work in high-voltage environments. High voltage is very dangerous for people, and they need to keep a corresponding distance at all times. Especially for various large machinery used in electric power, communication, mining, construction and other projects, the operation process is highly difficult. When operators work in high-voltage environments, it is difficult to judge the safe distance, which may cause psychological pressure or improper operations. They are extremely likely to touch high-voltage electricity, leading to accidents that cause vehicle damage and casualties. Therefore, high-voltage safety early warning is very important. The tower crane anti-high-voltage contact alarm is a high-voltage early warning device developed and produced by Telikang for this purpose. II. Working Principle When the tower crane anti-high-voltage contact alarm is working, it extracts the received 50Hz power frequency detection signal, eliminates interference signals through digital filtering, analyzes its signal strength, and automatically detects the distance between the device and the high-voltage line according to changes in distance and voltage, performing a series of front-end analysis and processing. When the analysis result reaches the preset early warning value, it immediately sends a wireless alarm signal to the receiver. After receiving the signal, the receiver alarms, prompting the user that the device is approaching strong electricity and to pay attention to safety. In addition, during use, the device does not generate early warnings for direct current, high frequency, or static electricity. It is mainly used to detect voltage early warnings for outdoor overhead lines above 220V and with a power frequency of 50-60Hz, because the electric field around the overhead single line is stable, the detection sensitivity is high, and it is easy for the product to receive the detection signal. III. Main Functional Features 1. The alarm distance of the transmitting end can be set. The alarm distance has a certain relationship with the voltage of the strong electricity. The higher the voltage, the greater the power frequency electric field strength it generates. By adopting different processing networks and setting different voltage levels, it can be set according to the relevant distance of the State Grid. During installation, pay attention to the angle and direction of the antenna, and whether there are obstacles, etc. 2. The alarm methods are flexible and diverse. It can output a normally open contact (passive), which closes when alarming. CAN bus and 485 interface control output can be added. 3. It supports a wide variety of voltage levels. Currently supported voltage levels include 10KV, 35KV, 110KV, 220KV, and custom voltage levels are also available. 4. It has a wide range of applications. It can be used in aerial work vehicles, aerial work platforms, lifting machinery, tower cranes, cranes, and seat vehicles. 5. The power supply method is flexible. Both the transmitting module and the receiver can be powered by DC24V or by batteries. 6. The transmission distance is long. In a wireless and barrier-free environment, the communication distance can reach 200 meters. IV.
