Problems solved by technology

[0004] However, in production and actual use, even if a fuse and a current-limiting chip are added to the front end of the DC-DC, DC-DC partial short-circuit failures will still occur, and TVS is mainly used for ESD (Electro-Static Discharge, electrostatic discharge) protection. Surge and overshoot cannot be effectively protected
The existing technology cannot effectively prevent the occurrence and development of chronic failure by preventing instantaneous failure

Abstract

The invention relates to data service equipment technology, and discloses a wireless data service equipment self-diagnosis method and a wireless data service equipment self-diagnosis system. The method comprises: acquiring effective values of working parameters of DC-DC in a low power consumption working mode in the equipment; and if the different between the effective values and normal parameter values is greater than a preset threshold, determining that the equipment has a fault. The method can prevent malign development of the fault of the high heat flux data service terminal equipment caused by DC-DC chronic failure, and ensures the use safety of the data service terminal equipment.

Description

technical field [0001] The invention relates to data service equipment technology, in particular to a self-diagnosing method and system for wireless data service equipment. Background technique [0002] Compared with 2G, data service is the main growth driver of 3G market development. Compared with traditional 2G voice services, data services will have long-term use and high power consumption. For example, the widely popular STICK data card in the market has a current of 500-700mA and a heat flux of 200W / L under extreme use. Much higher than other consumer electronics products, its thermal characteristics have attracted much attention. Due to monthly subscription and other reasons, even if the user does not use it, he will hang on the Internet for a long time and be in a low power consumption mode, including standby (standby current < 100mA) and low power consumption mode (running data services under strong signal, only maintaining the connection, Working current <&l...
