Inspection system components

1.PDA mobile terminal

PDA mobile terminal by the inspectors to inspect the transmission line to carry, 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, Guard Tour System 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 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 management of real-time voice calls.

Third, GPS positioning module

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

(1) Number of channels: 20;

(2) hot start time: 2s;

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