Embodiment Construction

[0036] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, and the specific design takes a real-time clock as an example.

[0037] The block diagram of the device of the present invention is as figure 1 As shown, it includes a backup power supply unit 101 , a volatile storage unit 102 , a microprocessor unit 103 and a measurement unit 104 .

[0038] The backup power supply unit 101 is connected to the volatile storage unit 102. Its main function is to automatically switch the volatile storage unit 102 to the backup power supply 101 for power supply when the main power supply fails or loses power, so as to maintain the most basic power of the chip. requirements to ensure that data is not lost.

[0039] Standby power supply unit 101 : mainly some small-capacity batteries, such as a general 3V / 50mAH button battery or a button lithium battery that can be recharged. For chips such as real-time clock...

Abstract

The invention discloses a device for testing the function of a small capacity spare battery and the method thereof, wherein the device comprises a spare battery unit 101, a volatile memory unit 102, a micro processing unit 103 and a measurement unit 104, wherein the spare battery unit 101 and the volatile memory unit are connected through an interface of the spare battery unit; when a main power supply is out of work or has power down, the volatile memory unit 102 shifts automatically to the spare battery unit to be supplied with power; the volatile memory unit 102 has the function of storing data, or can provides instant messaging; the micro processing unit 103 is used for reading the voltage measurement information of the spare battery of the measurement unit 104 and the data information of the volatile memory unit 102, judges if the spare battery operates normally and reports the result; the measurement unit is used to shirt the voltage of the spare battery and performs measurement. The invention judges the working state of the spare battery according to the voltage signals of the spare battery and determines simply and effectively the consumption of the battery according to the voltage.

Description

technical field [0001] The invention relates to the field of single-board-level automatic testing of communication systems and personal electronic tools, specifically, a working state testing device and method for small spare batteries in electronic equipment and personal electronic products. [0002] The test device and method of the invention are applicable to the application of small hand-held equipment, the application of low-voltage volatile memory of system single board to save configuration data or real-time clock and the aspect of electronic products of low-voltage volatile memory application. Background technique [0003] In communication electronic equipment and personal electronic products, many products need to use backup battery power supply. General communication main control boards, PC main boards, personal handheld electronic products and other electronic products mostly use backup batteries to provide low-voltage volatile memory to save certain configuration...
