Wtau WTYJ-YJQ Type Crane Anti-Electric Shock Early Warning System

1. Industry Pain Points

In-depth Analysis of Industry Pain Points

​

At worksites in fields like power infrastructure construction and building construction, equipment operation under high-voltage lines has long faced severe challenges:

• ​Spatial Perception Dilemma:Large machinery such as crawler cranes and wheeled cranes have a large operating radius, making it difficult for operators to accurately judge the real-time distance between equipment components (e.g., booms, buckets) and live conductors.
• ​Fatal risk threshold:When the distance between the equipment and high-voltage lines of ≥10kV is ＜5 meters, breakdown discharge may occur (in accordance with the DL 5009.2-2013 standard).
• ​Accident Chain Reaction:Electric shock → equipment damage (direct loss ＞2 million yuan/unit) → casualties (mortality rate ≥60%) → project suspension (construction period delay of 30 days +) → damage to corporate reputation.

According to the 2022 accident report of a provincial-level electric power construction group: High-voltage electric shock accounts for 34% of total construction accidents, and 100% of them are preventable accidents.

2. Product Overview

Wtau WTYJ-YJQ Anti-Electric Shock Early Warning System consists of an electric field sensor installed at a high position on the roof, a battery compartment, and a monitoring host in the driver's cab.The sensor is extremely sensitive to the surrounding high-voltage electric field. Once it detects that the vehicle is approaching lines of specific voltage levels (e.g., 220V, 10KV, 35KV, 110KV, 220KV), it immediately sends out an alarm signal wirelessly. The receiving host then triggers a voice broadcast (e.g., "XXKV high voltage danger"), and at the same time activates sound and light warnings, sends switch signal, communicates through the RS485 port, and uploads alarm information to the cloud platform. This series of real-time feedback mechanisms aims to quickly remind operators to avoid risks and prevent high-voltage electric shock accidents.

3. Core Functions

• ​Cross-voltage level early warning:Covers the full range of electric field detection from 220V to 220KV, accurately distinguishes key voltage thresholds such as 10KV/35KV/110KV, and triggers protection mechanisms in seconds.
• ​Reliable Signal Relaying:Based on a wireless transmission network in the dedicated 410-490MHz frequency band, it has barrier-free communication capability of over 100 meters, ensuring alarm reachability in scenarios such as tunnels and jungles.
• ​All-Weather Operation Guarantee:The sensor has an IP65 protection shell and a wide temperature range design of -40℃ to 85℃, ensuring continuous and stable operation in harsh environments such as mines and construction sites.
• ​Extension of Digital Management:An optional IoT module can be installed to connect to the cloud platform, enabling real-time acquisition of equipment positioning and alarm information, and realizing centralized safety supervision of multi-unit across regions.

4. Installation Method

Anti-Electric Shock Early Warning Sensor:Installed on the top of the crane's boom.

Anti-Electric Shock Early Warning Battery Compartment:Installed near the sensor to supply power to the sensor.

Anti-Electric Shock Early Warning Monitoring and Alarm Device:Installed in the driver's cab.

5. Product Details

a.Anti-Electric Shock Early Warning Sensor:A safety device used to detect and give early warning of electric shock risks. It detects the intensity of the electromagnetic field generated by surrounding high-voltage wires through a built-in electromagnetic field sensor. When the detected electromagnetic field exceeds the preset safety threshold, it will also issue an alarm to remind workers to avoid electric shock accidents.

b.Anti-Electric Shock Early Warning Battery Compartment:A device with anti-electric shock early warning function, mainly used for battery storage and testing to ensure the safety of batteries during storage and testing.

c.Anti-Electric Shock Early Warning Monitoring and Alarm Device:A device used to real-time monitor changes in the electric field of high-voltage lines and prevent electric shock accidents. It real-time perceives high-voltage signals in the surrounding environment through the front-end detection unit, and transmits the signals to the receiving end early warning unit through wireless communication. When it detects that there are operating vehicles near the high-voltage lines, it immediately activates the alarm mechanism and emits a clear and loud warning sound to remind the driver to pay attention to the safety distance and avoid electric shock risks.
