In order to ensure the reliability of the miner's lamp, after the battery capacity decays after a period of use, it can only be scrapped, resulting in great waste
Moreover, the miner's lamps on the market do not have a battery capacity reminder function, and it is difficult for miners to accurately estimate the remaining available time during use
On the other hand, most miner's lamps do not have charging management function or the charging management method is simple

Embodiment
[0035] see figure 1 , the mining lighting fixture of the present invention is mainly composed of a power supply module, a PWM charging circuit, a value detection channel switching circuit, a main lamp and an auxiliary lamp circuit, an operational amplifier and a comparator circuit, a charging state and a battery capacity indicating circuit, a main control circuit, and a serial port ESD Protection and other components. The serial port ESD protection module is connected to the PWM charging circuit module, and the PWM charging circuit module is connected to the power supply module. The PWM charging circuit module is divided into N channels of independently operating PWM charging channels, which are respectively charged independently for the charging channels of the N power supply module. When the charging channel fails, it will not affect the normal operation of the charging channels of other power modules;

The invention discloses a battery-exchangeable mining illuminating lamp and a charging management method of the same. The battery-exchangeable mining illuminating lamp includes a main control module,a power supply module, a PWM charging circuit module, a value detection channel switching circuit module, a main lamp / auxiliary lamp circuit module, an operational amplifier and comparator circuit module, a battery fault and capacity indicating lamp module, and a serial port ESD protection module, wherein the power supply module, the PWM charging circuit module, the value detection channel switching circuit module, the main lamp / auxiliary lamp circuit module, the operational amplifier and comparator circuit module, the battery fault and capacity indicating lamp module, and the serial port ESDprotection module are connected with the main control module; the serial port ESD protection module is connected with the PWM charging circuit module; the PWM charging circuit module is connected withthe power supply module; and the PWM charging circuit module is provided with a PWM charging channel which is divided into N channels to operate independently to independently charge N charging channels of the power supply module respectively, and when one of the charging channels malfunctions, normal operation of other charging channels of the power supply module is not influenced. For the battery-exchangeable mining illuminating lamp with the above structure, when the battery capacity fades, the mine lamp can still be used stably only by exchanging a new battery; and the battery-exchangeable mining illuminating lamp has a safe and reliable charging management scheme and an electric quantity indication function.
Description
technical field [0001] The invention relates to the field of lighting lamps, in particular to a mining lighting lamp with a replaceable battery and a charge management method for the lamp. Background technique [0002] The miner's lamp is a special lighting fixture used in the mine, and it is an essential tool for underground workers, so the performance of the miner's lamp is very important. In order to ensure the reliability of the miner's lamp, after its battery capacity decays after a period of use, it can only be scrapped, resulting in great waste. Moreover, the miner's lamps on the market do not have a battery capacity reminder function, and it is difficult for miners to accurately estimate the remaining available time during use. On the other hand, most miner's lamps do not have a charging management function or the charging management method is simple. Contents of the invention [0003] In view of this, the present invention provides a battery-replaceable mine lig...
