Description

 The invention relates to electrical engineering and automation and can be used to organize automatic charge modes and form a large number of rechargeable batteries of head lamps, for example, when used in shaft lamps, as well as to organize parallel time tracking of personnel using head lamps.

 A device is known - a charging station - for charging batteries [1]. This charger contains an AI power source that is directly and parallel connected to the charge cells of the charger - special terminals for connecting AB batteries to the power supply.

 As a prototype, a charging station [2] was selected, which contains, as in the analogue, a power source and charging cells. The battery charge starts immediately when it is connected to the charger, and stops when disconnected from the charger. The known prototype device does not automatically control the state of the battery in the process of charging and control the charge process depending on the state of the battery, for example, stop charging when the battery reaches its rated capacity or signal that the battery is not ready for use, which can lead to battery recharging and their premature failure, as well as an incomplete charge of batteries and a decrease in the level of labor protection for miners.

 The essence of the claimed technical solution is an automated battery charging system containing power sources and charging cells, according to the invention, that the system contains a host computer and M modules combined with a computer of a common trunk addresses and data; the host computer is equipped with special “A-Charge” software, which automatically controls and manages the battery charge / discharge process by analyzing their measured electrical characteristics (current and voltage), makes decisions about changing the charge / discharge mode and gives commands for changing the mode, and also presentation of the received data in a user-friendly form; each module consists of a power supply (IP), a module controller (KM), an analog-to-digital converter (ADC), and N distribution and switching units (RCBs) connected by a local address and data highway and a local power highway; a controller equipped with a microcomputer receives control commands from the host computer, transmits them to the RCB and the ADC via the local address and data highway, receives data from the ADC, transmits them to the host computer, stores the received data, and in case of failure of the host computer, it assumes its functions maintaining the system; the distribution and switching unit contains L charge-discharge channels (SAM), each of which includes a charge current control device (UUT) AB, a discharge device (UR) AB, a color management device (UUT) of the light indicator (SI) of the states of the RF and AB and a switching device (KU) for connecting the channel to the ЗЯ, SI and ADC, the air defense system is controlled by the controller through the local address and data highway; an analog-to-digital converter at the command of the controller through the local highway of addresses and data measures the electrical characteristics (current and voltage) of the power supply at the output of the corresponding channel of the distribution and switching unit; the power supply provides power to all electronic modules of the module that are connected to the local power supply line; the total number of charge cells in the K system is related to the number of modules M, the number of distribution and switching units N and the number of charge-discharge channels in the RCS L is related by the relation K = M • N • L.

 The system is shown in the drawing. It consists of a host computer (1), modules (2), each of which consists of an IP power supply (3), a controller of a KM module (4), an analog-to-digital converter of the ADC (5), distribution and switching units of the RCB (6) containing charge-discharge channels of the SAM (7), which include KU switching devices (8), UUT charge current control devices (9), UR discharge devices (10), color control devices for warning lights (11), and from the charging cells of the SC (12) and the corresponding SI light indicators (13).

 Automated battery charging system operates as follows. The host computer running the A-Charge program regularly, for example, 8 times per hour, sends commands to measure the electrical parameters of all the charging cells in the system. Commands on the common address and data highway are transmitted to the module controllers and from them on the local address and data highway to distribution and switching blocks and the corresponding charge-discharge channels, as well as to the ADC. The measured values of the parameters are transmitted to the controllers, and from them to the host computer. The data obtained are analyzed by the A-Charge program. Based on the analysis of the data obtained, conclusions are made about the state of the battery (put on charge / discharge, removed from charge / discharge, charged / undercharged to rated capacity, serviceable / faulty) and decisions are made about starting / continuing / stopping charge / discharge of the battery and turning it on / switching off the light indication, indicating the beginning / continuation of the charge / discharge process, about the battery’s readiness for operation or about an emergency situation (for example, about a battery malfunction, about incorrect actions of maintenance personnel). The results of the analysis and the data underlying them are recorded in the corresponding databases. Commands for the implementation of the decisions made are transmitted from the host computer to the module controllers and further to distribution and switching units and charge-discharge channels.

 An automated charge system for 256 rechargeable batteries was created, consisting of 256 charging cells and 256 three-color light indicators, from the host computer, equipped with the A-Charge control program and 4 modules, combined with the host computer by a common address and data highway; each module contains a module controller, an analog-to-digital converter and 16 distribution and switching units connected by a local address and data highway and a local power highway with a power source; each distribution and switching unit contains 4 charge-discharge channels, each of which consists of a charge current control device, a discharge device, a color indicator light control device and a switching device for connecting the channel to charging cells, light indicators and an analog-to-digital converter.

 Thus, the proposed battery charging system significantly expands the functionality of the charger: it provides automatic control of the state of the batteries during the charge / discharge process, automatic control of the charge / discharge process based on data on the state of the battery, organization of the automatic mode of battery formation and parallel automatic personnel personnel accounting, which, in turn, ensures a full charge of the battery and eliminates overcharging, significantly increasing the service life Already, it increases the level of labor protection.
