Abstract

The invention discloses a battery management device for a rescue capsule, which is characterized in that: a tested battery positive electrode is respectively connected with a first voltage acquisition module and a second voltage acquisition module, and an output end of a current sensor is connected with a current acquisition module; a first temperature sensor, a second temperature sensor and a third temperature sensor are respectively connected with the first voltage acquisition module, the second voltage acquisition module and the current acquisition module, and a control module, the first voltage acquisition module, the second voltage acquisition module and the current acquisition module are sequentially connected by communications; and the control module is connected with an intrinsically safe touch screen through an isolation module. In the invention, the real-time monitoring display of the running state of batteries of the rescue capsule can be realized; a quick alarm for the battery fault condition can be given, and fault switch signals are output; and the intrinsically safe touch screen and a strong power part are isolated by the isolation module so as to ensure the safety of operating personnel.

Description

Technical field [0001] The invention relates to the field of electronic equipment monitoring, in particular to a rescue cabin battery management device, which is applied to the protection of lithium batteries for the rescue cabin underground in coal mines. Background technique [0002] The power supply device of the rescue cabin is generally divided into two parts: mine power supply and uninterruptible power supply UPS. The rescue cabin is connected to the mine power supply under normal conditions, and the voltage and current are adjusted by the transformer conversion equipment to adapt to the equipment specifications in the cabin. In the event of a mine disaster, the air-conditioning, lighting, and electronic equipment control in the underground rescue cabin must be maintained by battery power. Whether it can provide power for the power-consuming equipment of the rescue cabin and maintain its long-term stable operation has a great impact on extending the life-saving time. At p...
