Embodiment 1

[0025] Such as figure 1 As shown, the UPS storage battery detection device includes an MCU control module (2), which is characterized in that: the MCU control module is connected to a sensor module (1), a key input module (10), and an LCD display module (4) , a wireless communication module (8) and an I / O reserved port (9); the wireless transceiver module (8) is connected to the mobile device terminal (7).

Embodiment 2

[0027] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0028] The MCU control module (2) is responsible for controlling the operation of the sensor nodes, including data acquisition control, data A / D conversion, data accuracy calibration and data communication with the outside world.

[0029] The sensor module (1) is responsible for collecting physical information in the monitoring area and converting it into a voltage analog signal within the detectable range of the micro-processing internal A / D converter.

[0030] The key input module (10) adopts a light touch button circuit, adds a pull-up resistor to keep the key detection at a high level by default, and adopts a low level trigger mode. As long as a key is pressed, the corresponding key function is triggered. It is mainly used to select the function menu and set the parameters of the device and other operations. .

[0031] The wireless communication module (8) adopts ...

Abstract

The invention provides a UPS (Uninterrupted Power Supply) storage battery detection device. The UPS storage battery detection device comprises an MCU (Main Control Unit) control module (1), a sensor module (2), a key input module (3), an LCD display module (4), a wireless communication module (5) and an I / O reserved port (6),wherein the MCU control module takes the Charge Time Measurement Unit (CTMU) embedded in PIC series single chips of a Microchip Company, works in cooperation with an A / D (Analogue / Digital) converter, and can be used for accurately measuring time, capacitance and relative change of the capacitance, the sensor module (2) is provided with a high-precision capacitive touch sensor for data acquisition and used for converting micro-deformation caused by the swelling of the UPS storage battery into the variable quantity of the capacitance, and the I / O reserved port (6) is used for driving a peripheral circuit. The UPS storage battery detection device is capable of effectively improving the accuracy and the speed of detection on the UPS storage battery, and has the characteristics of simple structure, low price and the like. The problem of battery swelling resulting from bad battery protection circuit, poor performance of a charger and the like is solved, the current situation of difficult maintenance of the UPS storage battery is improved, and meanwhile, potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a UPS storage battery detection device. Background technique [0002] UPS uninterruptible power supply is the power guarantee for loads in many industries. It maintains the continuity of power supply and the safety of the power supply system. UPS plays an important role in safety protection at all times. The battery is an important part of UPS. The battery is the final guarantee for power supply. It is undoubtedly the last insurance in UPS, and its quality is directly related to whether the UPS can work normally. According to the survey and statistics, the analysis of accidents caused by UPS failure to supply power normally found that more than 50% of the accidents were caused by battery failures. necessity and urgency. [0003] At present, UPS batteries generally lack correct daily maintenance and accurate detection methods, which leaves a major safety hazard for the no...
