According to the first temperature control instruction, starting a temperature rise control channel in the target temperature control channel to perform temperature rise control on the target optical instrument, wherein the temperature rise control process comprises the following steps: the heating control channel comprises a main heating channel and an auxiliary heating channel, wherein the main heating channel is provided with a main heating threshold mark, the main heating channel is a heating channel established based on a heating wire heating principle, when the heating wire heating principle is that electric energy passes through the heating wire through current, the electric energy is converted into heat energy, the heating wire is heated, when the current passes through the heating wire, due to the existence of a resistor, the electric energy is converted into heat energy, the heating wire is heated and heats, the heating value and the temperature of the heating wire can be controlled by controlling the size and the time of the current, and the heating wire is arranged on the surface of a target optical instrument to serve as the main heating channel. The control accuracy of the main heating channel to the temperature is smaller than that of the auxiliary heating channel, for example, the control accuracy of the main heating channel is 1 ℃, the temperature is 1 ℃ as a main heating threshold, if the temperature to be controlled is smaller than 1 ℃, the control is not needed through the main heating channel, and the control result is easy to be inaccurate.
The auxiliary heating channel is a heating channel established based on a power consumption heating principle, the power consumption heating principle is to realize power consumption control by adjusting the working frequency and voltage of the target optical instrument, the temperature control can be realized by controlling the power consumption, the temperature control precision of the auxiliary heating channel is higher, and the auxiliary heating channel is generally used for controlling smaller heating temperature, such as 0.2 ℃.

At this time, the temperature adjustment at 0.4 ℃ is further needed, the control accuracy of the main heating channel cannot perform the process of smaller temperature, and the control result generates larger deviation, so that on the basis of the first temperature control result, the auxiliary heating channel is started to control the first temperature difference fraction of the first temperature difference, that is, the adjustment of the first temperature difference fraction is realized by properly adjusting the working frequency and the working voltage of the target optical instrument, specifically, the test can be performed by using the same type optical instrument, the temperature changes corresponding to the difference of the working frequency and the working voltage are determined, and then the adjustment values of the frequency and the voltage are determined according to the first temperature difference fraction, so as to obtain the second temperature control result, wherein the second temperature control result refers to the temperature of the target optical instrument after the control of the auxiliary heating channel, and the second temperature control result is used as the temperature increase control result of the target optical instrument. If the first temperature difference is not in the primary temperature rise threshold, namely the first temperature difference is a decimal between 0 and 1, the secondary temperature rise channel is directly started to control the first temperature difference, and a temperature rise control result is obtained. The technical effect of improving the heating control precision and accuracy is achieved.
Specifically, the process of starting the cooling control channel in the target temperature control channel to perform cooling control on the target optical instrument is as follows: the cooling control channel comprises a main cooling channel and an auxiliary cooling channel, wherein the main cooling channel is provided with a main cooling threshold value mark, the main cooling threshold value can be set to be 1 ℃, the main cooling channel is a cooling channel established based on a liquid nitrogen refrigerating principle, the basic principle of liquid nitrogen refrigerating is to utilize the physical characteristics of liquid nitrogen, the liquid nitrogen is injected into refrigerating equipment to enable the liquid nitrogen to evaporate and absorb heat, so that the aim of refrigerating is achieved, and particularly, when the liquid nitrogen evaporates in the refrigerating equipment, the liquid nitrogen can absorb heat on the surface of a target optical instrument, so that the temperature of the target optical instrument is reduced, and the effect of cooling is achieved.
