Optionally, if the temperature difference is smaller than the first preset temperature threshold, the specific steps of generating the processing scheme based on the current temperature include:
judging whether the current humidity exceeds a first preset humidity threshold value or not;
if the current humidity does not exceed the first preset humidity threshold, heating the target electronic control cabinet based on a preset temperature control device;
if the current humidity exceeds the first preset humidity threshold, judging whether a condensation device exists or not;
if the condensation device exists, condensation is carried out based on the condensation device and a preset condensation rule;
and controlling the condensed liquid to be led out of the target electric control cabinet.
By adopting the technical scheme, whether the current humidity exceeds the first preset humidity threshold value is judged, if the current humidity does not exceed the first preset humidity threshold value, the current humidity in the target electric control cabinet is lower, namely, the water vapor contained in the air is less, so that the temperature in the electric control cabinet is directly increased through the temperature control device, the saturation degree of the water vapor in the air is improved, and the condensation possibility is reduced; if the current humidity exceeds a first preset humidity threshold, the current humidity in the target electric control cabinet is indicated to be higher, namely, the water vapor contained in the air is more, whether a condensation device exists or not is judged in order to prevent the condensation phenomenon, if so, the water vapor in the target electric control cabinet can be condensed at the condensation device through a preset condensation rule, and condensed liquid is led out of the target electric control cabinet under control, so that the water vapor content in the air is reduced, namely, the current humidity is reduced, and the possibility of condensation is further reduced.

If the temperature exceeds the dew point temperature, the real-time temperature of the target region is far higher than the dew point temperature of the corresponding time, and the condensation phenomenon is rarely generated, so that the condensation phenomenon can be prevented by directly heating the water vapor without causing great influence even if the water vapor is not treated;
if the temperature is not exceeded, the real-time temperature of the target region is not far higher than or even lower than the dew point temperature of the corresponding time, the condition that the dew phenomenon exists is extremely high, if the current humidity is not reduced, the high temperature is required to be kept continuously, otherwise the dew phenomenon is easily caused, and therefore, the temperature rising treatment is required to be carried out, and meanwhile, an alarm is carried out to remind a worker of timely carrying out sealing maintenance, so that the energy loss is reduced.

Specifically, in this embodiment, the air circulation status, that is, the circulation status of air in the target electronic control cabinet and air outside the target electronic control cabinet, including circulation and non-circulation, may be determined according to the humidity change status, if the humidity change status indicates that the relative humidity corresponding to different time nodes has changed, the air circulation is determined, and if the humidity change status indicates that the relative humidity corresponding to different time nodes has not changed, the air is determined not to circulate.
Step S303: and acquiring the tightness of the target electric control cabinet based on the air circulation condition.
Specifically, in this embodiment, the tightness includes good and bad, and the air circulation condition indicates that the tightness of the target electronic control cabinet is good.
Step S304: judging whether the tightness meets the tightness requirement.
Specifically, in this embodiment, the sealing property is required to be good.
Step S305: if the tightness meets the tightness requirement, condensation is performed based on the condensation device and a preset condensation rule.
According to the condensation prevention method for the electric control cabinet, humidity change conditions are obtained according to humidity data, target air circulation conditions are obtained according to the humidity change conditions, the tightness of the target electric control cabinet is obtained according to the air circulation conditions, whether the tightness meets the tightness requirement is judged, if yes, the tightness of the target electric control cabinet is good, external air is difficult to enter the cabinet, therefore, water vapor in the target electric control cabinet is condensed at a condensation device through a preset condensation rule, the current humidity is reduced, and the condensation possibility is reduced.
Referring to fig. 4, in one implementation manner of the present embodiment, after step S304, it is determined whether the tightness meets the tightness requirement, steps S401 to S407 are further included:
step S401: and if the tightness does not meet the tightness requirement, acquiring the climate characteristics of the target region.
Specifically, in this embodiment, the target region is a region where the target electronic control cabinet is located, for example, a city or a county where the target electronic control cabinet is located, and the climate characteristics include a temperature and an air humidity of the target region.
Step S402: based on the climate characteristics, the normal temperature and the normal humidity of the target region are obtained.
Specifically, in this embodiment, the normal temperature, that is, the temperature range in which the target region appears most, may be set according to different time nodes (such as quarterly or month, etc.), for example, when the temperature is 25 to 35 degrees celsius for 7 months in a certain place, the normal temperature is 25 to 35 degrees celsius for 7 months in a certain place; the normal humidity, i.e. the humidity range in which the target zone is most exposed, may be set according to different time nodes (quarterly or month etc.).
Step S403: and acquiring a normal dew point temperature corresponding to the normal humidity.
Specifically, in this embodiment, the normal dew point temperature is the dew point temperature corresponding to the normal humidity.
Step S404: and obtaining a normal state difference value between the normal state temperature and the normal state dew point temperature.
Specifically, the normal difference is a difference obtained by subtracting the normal dew point temperature from the normal temperature, and in this embodiment, when the calculation is performed, the lowest temperature in the temperature range corresponding to the normal temperature is used for the calculation.
Step S405: and judging whether the normal state difference value exceeds a second preset temperature threshold value.
Specifically, in this embodiment, the second preset temperature threshold is a preset judgment standard for judging whether there is a condensation risk in the target electric control cabinet in the target region for a long time.
Step S406: if the normal state difference exceeds a second preset temperature threshold, heating the target electric control cabinet based on a preset temperature control device.
Specifically, in this embodiment, when the normal state difference value exceeds the second preset temperature threshold, it indicates that there is no condensation risk in the target electronic control cabinet in the target region for a long time, so that even if the tightness of the target electronic control cabinet is not improved, no great influence is caused, and therefore, the temperature in the target electronic control cabinet is directly raised.
Step S407: if the normal state difference value does not exceed the second preset temperature threshold value, heating the target electric control cabinet based on the preset temperature control device, and giving an alarm.
Specifically, in this embodiment, when the normal state difference value does not exceed the second preset temperature threshold value, it indicates that there is a condensation risk in the target electronic control cabinet in the target region for a long time, if the tightness of the target electronic control cabinet is not improved, the target electronic control cabinet needs to be heated for a long time, and a large amount of energy consumption is generated, so that an alarm is required to remind a worker to improve the tightness of the target electronic control cabinet in time, so as to reduce the condensation risk in the target electronic control cabinet, thereby being beneficial to reducing energy consumption.
According to the condensation preventing method for the electric control cabinet, if the tightness does not meet the tightness requirement, the fact that external air easily enters the target electric control cabinet is indicated, so that even if the current humidity in the target electric control cabinet is reduced through condensation, the current humidity can be quickly returned due to circulation with the external air, energy waste is caused, in order to reduce energy consumption and prevent the condensation phenomenon, the normal temperature and the normal humidity of a target region and the normal dew point temperature corresponding to the normal humidity are obtained, the normal difference value is obtained according to the normal temperature and the normal dew point temperature, and whether the normal difference value exceeds a second preset temperature threshold value is judged.
If the temperature exceeds the preset value, the real-time temperature of the target region is far higher than the dew point temperature of the corresponding time in most of the time, and the condensation phenomenon is rarely generated, and the condensation phenomenon can be prevented by directly heating the target region without greatly influencing the water vapor even if the water vapor is not treated.
If the temperature is not exceeded, the real-time temperature of the target region is not far higher than or even lower than the dew point temperature of the corresponding time, the condition that the dew phenomenon exists is extremely high, if the current humidity is not reduced, the high temperature is required to be kept continuously, otherwise the dew phenomenon is easily caused, and therefore, the temperature rising treatment is required to be carried out, and meanwhile, an alarm is carried out to remind a worker of timely carrying out sealing maintenance, so that the energy loss is reduced.

Specifically, in this embodiment, the humidity difference is a difference obtained by subtracting the air humidity from the current humidity.
Step S503: and judging whether the humidity difference exceeds a second preset humidity threshold.
Specifically, the second preset humidity threshold is a preset judgment standard for judging whether the current humidity is far higher than the air humidity, in this embodiment, if the current humidity exceeds 120% of the air humidity, it indicates whether the current humidity is far higher than the air humidity, and of course, other values may be set according to the actual situation.
Step S504: if the humidity difference value does not exceed the second preset humidity threshold value, heating the target electric control cabinet based on the preset temperature control device.
Step S505: if the humidity difference exceeds a second preset humidity threshold, ventilation is performed in the target electric control cabinet based on a preset ventilation rule, and after ventilation is finished, temperature rise is performed in the target electric control cabinet based on a preset temperature control device.
Specifically, the preset ventilation rule is a preset rule for exchanging air in the target electronic control cabinet with air outside the target electronic control cabinet, and in this embodiment, ventilation is finished only after the current humidity is equal to the air humidity.
According to the condensation prevention method for the electronic control cabinet, if the condensation device does not exist, the fact that condensation cannot be carried out on water vapor in the target electronic control cabinet at the condensation device is indicated, so that the current humidity is reduced, in order to prevent the water vapor from being condensed on electronic components, a humidity difference value between the air humidity and the current humidity is obtained, whether the humidity difference value exceeds a second preset humidity threshold value is judged, if the humidity difference value does not exceed the second preset humidity threshold value, the fact that the difference between the air humidity and the current humidity is not large is indicated, the current humidity cannot be reduced through external air is indicated, and therefore the possibility of condensation can be reduced only through heating the inside of the target electronic control cabinet; if the temperature exceeds the preset temperature, the air humidity is greatly different from the current humidity, so that the current humidity can be reduced by ventilating the target electric control cabinet, and the temperature in the target electric control cabinet is raised after the ventilation is finished, so that the possibility of condensation is further reduced.
Referring to fig. 6, in one implementation manner of the present embodiment, after step S109, it is determined whether the humidity change trend and/or the temperature change trend meet the corresponding change requirement, steps S601 to S605 are further included:
step S601: and if the humidity change trend and the temperature change trend both meet the corresponding change requirements, acquiring a historical heating record.
Specifically, in this embodiment, if both the humidity variation trend and the temperature variation trend meet the corresponding variation requirements, it indicates that the current temperature and/or the current humidity variation condition is smaller or not changed, and it can be predicted that the current temperature and/or the current humidity will not be mutated in a short time, so there is a smaller risk of condensation; the historical temperature rise record is the record of the over-temperature in the target electric control cabinet in the past.
Step S602: and acquiring a constant temperature rise time node based on the historical temperature rise record.
Specifically, the constant temperature rise time node is a time node that is constantly heated, and in this embodiment, the constant temperature rise time node is a time interval and can be set according to quarterly, monthly, and hour.
Step S603: judging whether the current time node is a constant temperature rise time node or not.
Specifically, in this embodiment, whether the current time node is a constant temperature rise time node is determined, that is, whether the current time node is within a time interval in which the constant temperature rise time node is located is determined.
Step S604: if the current time node is a time node with constant temperature rise, the temperature in the target electric control cabinet is raised based on a preset temperature control device, and an alarm is given.
Specifically, in this embodiment, if the current time node is a constant temperature rising node, it indicates that in the past time node, for example, in the past 0 days of the month, the temperature in the target electronic control cabinet is usually raised, so that it is predicted that the temperature in the target electronic control cabinet needs to be raised even in the 0 days, and because the current humidity and/or the current temperature are not obtained, an alarm needs to be given to remind a worker to process in time, and the temperature in the target electronic control cabinet needs to be raised to reduce the condensation risk.
Step S605: and if the current time node is a very warmed time node, giving an alarm.
According to the condensation prevention method for the electric control cabinet, if the humidity change trend and the temperature change trend both meet the corresponding change requirements, the fact that the current temperature and/or the current humidity change condition are not large or not changed is indicated, a small condensation risk exists, in order to further reduce the condensation risk, a normally-heated time node is obtained according to a historical heating record, whether the current time node is the normally-heated time node is judged, if yes, the fact that the condensation phenomenon is likely to occur in the current time node is indicated, therefore, the temperature in the target electric control cabinet needs to be raised in time, an alarm is given, and accordingly workers are reminded of timely maintenance.
