Problems solved by technology

If the battery fails and is not found, it will cause the UPS to fail to operate normally or shut down, which may eventually lead to disastrous consequences. In many cases, the battery is also affected by the environment and its own performance, causing the battery to fail too quickly. It cannot be inferred in advance during use, causing the UPS to suddenly fail to work

Embodiment 1

[0025] The present invention provides such figure 1 A battery critical failure detection method is shown, and the detection method is as follows:

[0026] Step 1: Battery traceability. Before the battery is assembled in the UPS, its manufacturer, production time, battery performance parameters and service life are traced through the battery QR code, and these data are stored in the memory;

[0027] Step 2: Install detection memory, single-chip microcomputer and alarm, respectively install the memory, single-chip microcomputer, alarm and wireless communication module in the UPS, and use them synchronously with the battery, and the single-chip microcomputer communicates with the CPU controller inside the UPS and the UPS through the wireless communication module remote device connection;

[0028] Step 3: Install a current and voltage sensor and a coulomb counter, and connect the charging and discharging cables of the battery to the current and voltage sensor. The current and vol...

Embodiment 2

[0036] In step seven, the temperature and dust concentration are detected. When the battery is charging and discharging, the temperature and humidity sensor and the dust concentration sensor can detect the ambient temperature and dust concentration of the battery, the charging connection line, the discharge connection line, and the UPS, and the temperature and humidity sensor And the dust concentration sensor converts the signal into a digital signal through the A / D converter and sends it to the single-chip microcomputer. The single-chip microcomputer sends the signal to the remote device for data processing and detection, and compares the surrounding temperature of the battery, charging connection line and discharge connection line with the temperature inside the UPS. In contrast, when the dust concentration is high, the temperature rises everywhere is greater than the set value, and the voltage and current detection values ​​are normal, that is, the battery surface has poor he...

Embodiment 3

[0038]In step seven, the temperature and dust concentration are detected. When the battery is charging and discharging, the temperature and humidity sensor and the dust concentration sensor can detect the ambient temperature and dust concentration of the battery, the charging connection line, the discharge connection line, and the UPS, and the temperature and humidity sensor And the dust concentration sensor converts the signal into a digital signal through the A / D converter and sends it to the single-chip microcomputer. The single-chip microcomputer sends the signal to the remote device for data processing and detection, and compares the surrounding temperature of the battery, charging connection line and discharge connection line with the temperature inside the UPS. In contrast, when the temperature of a single location rises too high, it may be that the wiring is loose (poor contact, line aging), and timely maintenance is required;

Abstract

The invention discloses a method for detecting critical failure of a battery. The detection method is as follows: Step 1: battery traceability. Before assembling the battery in a UPS, trace its manufacturer, production time, battery performance parameters and battery performance parameters through a battery two-dimensional code. The service life, store these data in the memory, step 2: install the detection memory, single-chip microcomputer and alarm, install the memory, single-chip microcomputer, alarm and wireless communication module in the UPS respectively, use it synchronously with the battery, and the single-chip microcomputer passes through The wireless communication module is connected with the CPU controller inside the UPS and the remote device. Step 3: Install current and voltage sensors and coulomb counters. The present invention monitors the battery surrounding temperature, dust concentration, charging and discharging current and voltage, battery capacity and charging time in real time, traces the source of the battery, understands its basic data, and infers the battery failure time according to the data and the detection data, and timely Repair and replace batteries.

Description

technical field [0001] The invention relates to the field of battery critical failure detection, in particular to a battery critical failure detection method. Background technique [0002] As an important peripheral for computer information systems, communication systems, and data network centers, UPS power supplies are important in protecting computer data, ensuring the stability of grid voltage and frequency, improving grid quality, and preventing instantaneous power outages and accidental power outages from harming users. very important. As one of the indispensable pillars of UPS, the quality of the battery directly affects the operating quality of the UPS. If the battery fails and is not found, it will cause the UPS to fail to operate normally or shut down, which may eventually lead to disastrous consequences. In many cases, the battery is also affected by the environment and its own performance, causing the battery to fail too quickly. It cannot be inferred in advance...
