WTYJ-YJQ Anti-electrocution Early Warning System

1. Industry pain points

In-depth Analysis of Industry Pain Points

​

At the operation sites in fields such as power infrastructure and building construction, the operation of equipment under high-voltage lines has long faced severe challenges:

• ​Spatial perception dilemmaLarge machinery such as crawler cranes and tire cranes have a large operating radius, making it difficult for operators to accurately determine the real-time distance between equipment components (such as booms and buckets) and live conductors
• ​Fatal risk thresholdWhen the distance between the equipment and the high-voltage line of ≥10kV is less than 5 meters, breakdown discharge may occur (in accordance with the DL 5009.2-2013 standard).
• ​Chain reaction of accidentsElectric shock → Equipment damage (direct loss > 2 million yuan per unit) → Casualties (mortality rate ≥60%) → Project suspension (delay of over 30 days) → Damage to the company's reputation

The 2022 accident report of a provincial power construction group shows that high-voltage electric shock accounted for 341 to 310,000 tons of total construction accidents, and 1,001 to 310,000 tons were preventable accidents

2. Product Overview

Weite WTYJ-YJQ anti-electric shock Early Warning SystemIt is composed of an electric field sensor at the top of the vehicle roof, a battery compartment and a driver's cab monitoring host. The sensor is highly sensitive to the surrounding high-voltage electric field. Once it detects a vehicle approaching a line of a specific voltage level (such as 220V, 10KV, 35KV, 110KV, 220KV), it immediately wirelessly sends out an alarm signal. The receiving host immediately triggers a voice broadcast (such as "XXKV High Voltage Danger"), simultaneously activates sound and light warnings, sends switch signals, communicates through the RS485 port, and uploays alarm information to the cloud platform. This series of immediate feedback mechanisms is designed to quickly alert operators to avoid risks and prevent high-voltage electric shock accidents.

3. Core Functions

• ​Cross-voltage level early warningIt covers the full spectrum of electric field detection from 220V to 220KV, accurately distinguishes key voltage thresholds such as 10KV/35KV/110KV, and triggers protection mechanisms within seconds.
• ​Reliable signal relayBased on the dedicated frequency band of 410-490 MHZ, the wireless transmission network has barrier-free communication capabilities over 100 meters, ensuring the accessibility of alarms in scenarios such as tunnels and jungles.
• ​All-weather operation guaranteeThe sensor has an IP65 protective housing and a wide temperature range design from -40℃ to 85℃, ensuring continuous and stable operation in harsh environments such as mines and construction sites.
• ​Extension of Digital managementAn optional iot module can be installed to connect to the cloud platform, enabling real-time acquisition of equipment location and alarm information, and achieving centralized safety supervision of multiple units across regions.

5. Product Details

a.Anti-electric shock warning sensorA safety device for the detection and early warning of electric shock risk ‌ detects the intensity of the electromagnetic field generated by the surrounding high-voltage wires through the built-in electromagnetic field sensor. When the detected electromagnetic field exceeds the preset safety threshold, it will also sound an alarm to remind the staff to avoid electric shock accident ‌.

b.Anti-electric shock warning battery compartmentA device with an anti-electric shock early warning function, mainly used for battery storage and testing to ensure the safety of batteries during the storage and testing process.

c.Anti-electric shock early warning monitoring and alarm instrumentA DEVICE for real-time monitoring of electric field changes in high-voltage lines to prevent electric shock accidents ‌. It senses the high voltage signal in the surrounding environment in real time through the front-end detection unit and transmits the signal to the receiving end early warning unit via wireless communication. When it detects a working vehicle near the high voltage line, it immediately activates the alarm mechanism and emits a clear and loud warning sound to remind the driver to pay attention to safe distance to avoid electric shock risk ‌.
