Description

Technical Field

[0001] The present invention relates to the fields of intelligent control and wireless communication, and in particular to a remote wireless control system for a line crossing rapid network blocking device. Background Art

[0002] In the field of intelligent control and wireless communications, remote wireless control systems for rapid line crossing closure devices are key technologies for ensuring the safe operation of power lines. Existing closure control systems typically include basic wireless communication and motor rotation control functions, but these are relatively simple and suffer from the following deficiencies: Functional limitations: Existing technologies typically only provide basic control functions and lack advanced automation and intelligent features. Inconvenient operation: During field use, the simple functionality requires operators to perform tedious manual operations, reducing work efficiency. Lack of braking control: Existing driven vehicles lack electromagnetic braking control, which can pose a safety hazard when emergency stops or precise positioning are required. Low wire reeling efficiency: Existing systems lack a one-button electric ratchet control for automatic wire reeling, making the reeling process time-consuming and labor-intensive. Lack of tractor speed control: The tractor lacks speed control, making it impossible to flexibly adjust its operating speed according to actual needs. Energy consumption: Existing systems consume high amounts of energy during operation and lack effective energy-saving measures. Inadequate equipment status monitoring: Existing technologies lack real-time monitoring and self-diagnosis of key equipment status, such as battery charge, increasing the risk of equipment failure.

[0003] Publication number CN113741293B, "A Remote Communication Control System for a Multifunctional Transmission Line Operation Vehicle," describes a multifunctional transmission line operation vehicle placed on the transmission line's load-bearing rope. The portable handheld remote control terminal controls the vehicle, but the following issues exist: The driven vehicle lacks brake control, a one-button electric ratchet-controlled automatic wire reeling function, and a tractor vehicle lacks speed regulation. Compared to this patent, the proposed design offers the following advantages: 1. This design incorporates a brake lock drive function for the tractor vehicle to control the driven vehicle, utilizing an electromagnetic brake control module for power-off braking without energy consumption. 2. The tractor vehicle's drive rod retracts and controls the lower wire pressing wheel (driving wheel), automatically adjusting the stroke and pressure to accommodate wires of varying diameters (120mm²-630mm²). Furthermore, the pressure control provides a braking function for the tractor vehicle, with strong pressure control. 3. The drive rod's retractable control features a power-off lock function, enabling constant pressure to be set and maintained even during power outages, reducing energy consumption. 4. The system features battery charge data and self-test functions, ensuring device status is monitored before network shutdown. 5. It has a one-button electric control ratchet automatic line reeling function (the ratchet is used to adjust the width of the sealing net). Summary of the Invention
