The Tour System Consists Of Three Parts
- Jul 03, 2017 -

Transmission lines are an important part of the power system, is an important channel for power transmission. Most of the transmission line corridors in the suburbs of the wilderness, by bad weather, hillside geographical conditions and other objective natural conditions greater impact, its operational reliability directly affects the stable operation of the grid. Therefore, Guard Tour System it is necessary to carry out transmission line inspection, timely detection of line defects that threaten the line. The traditional transmission line inspections are mostly walking patrols or tour patrols, with visual observation, and the screening of various hidden or dangerous points in the environment of the route path. Traditional transmission line inspection by the impact of human factors, Guard Tour System in harsh weather conditions, the operation is very difficult, inspection quality is poor, easily lead to hidden or defective lines can not be dealt with in a timely manner.

Therefore, the construction of patrol system can not be underestimated. Tour system combined with RFID identification technology, 3G transmission technology and GPS positioning technology will fundamentally solve the above problems, the entire system by the PDA mobile terminal, PC server and Web client three parts.

Patrol system components

1.PDA mobile terminal

PDA mobile terminal by the inspectors to inspect the transmission line to carry, Guard Tour System the operating system for Windows CE 5.0, the hardware mainly includes RFID radio, 3G communications and GPS positioning three modules. Based on RFID, 3G, GPS transmission line inspection management system, the use of PDA's powerful features, combined with RFID identification technology and GPS positioning technology, the use of 3G wireless network fast and real-time communication with the server, to exchange a variety of effective data.

First, RFID radio module

RFID radio module is mainly installed on the tower RFID tags and scan the user area to write the state information, the read and write distance parameters: reading distance of about 3m, Guard Tour System write distance of about 1m, to meet the line inspection work requirements.

Second, 3G communication module

In the PDA mobile terminal built-in 3G communication module, PDA terminal and PC server to achieve real-time communication between the server. 3G communication module using TD-SCDMA standard, can simultaneously transmit voice and data information, to achieve transmission line inspection information data real-time transmission, Guard Tour System inspection personnel and operation and management personnel real-time voice calls.

Third, GPS positioning module

GPS positioning module using SIRF star III chipset, fully meet the requirements of the inspection system, the basic technical parameters:

(1) Number of channels: 20;

(2) hot start time: 2s;

(3) positioning accuracy: about 10m. GPS positioning module can be real-time access to the latitude and longitude location information.
