Temperature and smoke alarm system and battery formation and capacity grading equipment

The embodiment of the invention provides a temperature and smoke alarm system and battery formation and capacity grading equipment, and the temperature and smoke alarm system comprises a main control circuit, a sampling circuit, an alarm output circuit and a communication circuit which are connected. The main control circuit is used for controlling the sampling circuit to acquire the environment temperature and smoke information, acquiring the acquired environment temperature and smoke information, and inputting an alarm signal to the alarm output circuit when the acquired environment temperature exceeds a temperature alarm threshold value and/or the smoke information exceeds a preset value; the sampling circuit comprises one or more temperature sampling circuits used for collecting the environment temperature and smoke information used for collecting the corresponding environment temperature. The alarm output circuit comprises one or more temperature smoke alarms, different temperature smoke alarms are provi
