Gas chromatograph column box temperature control method and terminal equipment

The invention discloses a gas chromatograph column box temperature control method which comprises the following steps: controlling a heating element to heat a column box according to a temperature value in the column box acquired by a temperature measuring element and preset corresponding temperature rise control parameters; after the temperature in the column box reaches the initial set temperature, determining a plurality of target temperatures and control parameters required when the corresponding target temperatures are reached according to the separation temperatures of different gas components in the sample in the preset column box; determining a target temperature corresponding to the temperature value at the current moment; according to the absolute error value between the temperature value in the column box at the current moment and the corresponding target temperature, the preset switching threshold value and the preset switching condition, the corresponding control parameters are determined, and th
