Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] Fig. 1 is a flow chart showing detection method according to the present invention, with reference to Fig. 1, the method comprises the following steps:

[0027] Step S102, when adding a new ESC antenna device, if the ESC control unit receives multiple response frames in which the CRC check fails, the ESC control unit stops polling and sends a broadcast frame, and the new ESC antenna device and the original The address of the antenna device with electric adjustment is set to an invalid value;

[0028] Step S104, the ESC control unit reallocates an address for each original ESC antenna device according to the saved serial number of the original ESC antenna device; and

[0029] In step S106, if the electronically adjustable antenna device that sends the response frame that fails the CRC check succeeds in re-establishing a connec...

Abstract

The detection method includes following steps: step S102, when adding new electric adjusting antenna installation (EAAI), if electric adjusting control unit (EACU) receives response frame of CRC check failure for many times, then EACU stops polling and sends broadcast frame, and sets up invalid value for addresses of new EAAI and original EAAI; step S104, based on saved sequence number of original EAAI, EACU redistributes address for each original EAAI; step S106, if connection is reestablished successfully between EAAI, which send response frame of CRC check failure, and EACU, then it is detected out where address conflict occurs. Moreover, the invention can eliminate abnormal communications issue brought by occurred address conflict.

Description

technical field [0001] The present invention relates to the control and management of electronically adjustable antenna equipment, and more specifically relates to an address conflict detection method and system for electrically adjustable antenna equipment based on the AISG protocol. Background technique [0002] With the development of mobile communication technology, compared with the traditional antenna technology, the electrically adjustable antenna technology has the advantages of low operating cost and high efficiency, so it is increasingly valued by operators. Typically, an ESC antenna system consists of an antenna body (including a phase shifter and a transmission mechanism), an ESC controller, an ESC centralized control unit, a multiplexer, and leads. Among them, the ESC controller and the antenna body together constitute an independent ESC antenna device. Multiple ESC antenna devices are cascaded with the ESC centralized control unit through multiplexers and leads...
