In this embodiment, the user may input the indoor temperature upper limit value and the indoor temperature lower limit value to the automatic power supply device through the input device; at this time, the automatic power supply device acquires an upper limit value and a lower limit value of the indoor temperature of the building.
S02, acquiring the position and the area of the building, and acquiring the upper limit value and the lower limit value of the outdoor temperature of the building according to the position and the area;
because the weather forecast is acquired, geographical coordinate information is required to be used, all the longitude and latitude of the building are required to be acquired through GPS between the upper limit value and the lower limit value of the outdoor temperature of the building, namely the geographical coordinate information of the building is acquired, then an API request for acquiring the weather forecast is constructed according to the address, and the weather data is acquired by sending an HTTP request to the URL of the API; the API will return a response in JSON, XML or other data format; this response is parsed to extract the required weather data. And finally, extracting an outdoor temperature upper limit value and an outdoor temperature lower limit value from weather data in a keyword extraction mode.
S103, acquiring an outdoor temperature true value of the building through an outdoor temperature sensor;
the outdoor temperature of the building is the most direct influencing factor affecting the indoor temperature of the building, so that the current outdoor temperature is required to be obtained before the indoor required temperature is calculated, and the temperature is usually obtained directly by using a sensor installed outdoors.
In one possible embodiment, as shown in fig. 2, the steps further include S104, S105, S106, S108, and S109.
S104, setting a low-temperature operation time period, wherein the low-temperature operation time period comprises a start low-temperature operation time period and a stop low-temperature operation time period;
in the embodiment of the application, a user can perform timing management on energy supply of the steam system to the building, namely, if no person is active in the building (such as a holiday or an unmanned working period), in order to save energy, the user can set a low-temperature operation period for the automatic energy supply device, and the low-temperature operation period comprises starting the low-temperature operation period and stopping the low-temperature operation period. For example, the on-low temperature run time may be 2023, 9, 29, 00:00; the stop cold run time may be 2023, 10, 6, 23:00.

S106, determining the required temperature as the preset minimum temperature.
When the acquired current time is in the low-temperature operation mode, the automatic energy supply device can determine that the required temperature is the preset minimum temperature according to the low-temperature operation mode. When the required temperature is the preset minimum temperature, the water in the building can be in a liquid state, and in this embodiment, the low-temperature opening ratio may be 0 ℃.
In this embodiment, the preset minimum temperature may be 0 ℃, or may be 10 ℃, or may be any specific temperature value that enables water in the building to be in a liquid state, which is not specifically limited herein.
S107, inputting an upper limit value of the indoor temperature, a lower limit value of the indoor temperature, an upper limit value of the outdoor temperature, a lower limit value of the outdoor temperature and a true value of the outdoor temperature into a preset predicted indoor demand temperature model to output the indoor demand temperature, wherein the predicted indoor demand temperature model is used for calculating and outputting the demand temperature.
After the upper limit value of the indoor temperature, the lower limit value of the indoor temperature, the upper limit value of the outdoor temperature, the lower limit value of the outdoor temperature and the real value of the outdoor temperature are obtained, the upper limit value of the indoor temperature, the lower limit value of the outdoor temperature and the real value of the outdoor temperature are respectively input into a preset prediction indoor demand temperature model, so that the prediction indoor demand model obtains the indoor demand temperature after calculation, and the indoor demand temperature is output, wherein the prediction indoor demand model is as follows:
wherein,for the indoor required temperature, the temperature of the air is controlled,is the lower limit value of the indoor temperature,is the upper limit value of the indoor temperature,is a true value of the outdoor temperature,is an upper limit value of the outdoor temperature,is a lower limit value of the outdoor temperature,for the outdoor temperature compensation coefficient,is an indoor temperature compensation coefficient.

wherein,for the number of sets of historical indoor temperature data, the historical indoor temperature data of the set comprises indoor predicted temperatures and corresponding indoor real temperatures at the same moment,indoor predicted temperatures in the ith group of the historical indoor temperature data,is the indoor real temperature in the i-th group of the historical outdoor temperature data.
S108, judging whether the electromagnetic valve is in a starting state, wherein the electromagnetic valve is a switch valve for controlling the indoor temperature of the building; if not, step S109 is executed, and if yes, step S110 is executed.
The electromagnetic valve is used for controlling the switch valve of the indoor temperature of the building, for example, when heating is performed through the steam equipment in the building, the electromagnetic valve is used for balancing the air pressure at two sides of the board changing equipment in the steam system, if the air pressure at two sides of the board changing equipment is too large, the primary side electric valve of the board changing equipment cannot be adjusted, the electromagnetic valve is needed to control the air pressure at two sides of the board changing equipment, and then the switch valve (the primary side electric valve of the board changing equipment) of the indoor temperature of the building is controlled, so that the electric valve of the board changing equipment can be opened. The automatic energy supply device firstly judges whether the electromagnetic valve on the primary side of the steam system board is in an open state, and if the electromagnetic valve is in the open state, the step S110 can be directly executed; otherwise, step S109 is performed.
S109, opening the electromagnetic valve.
If the electromagnetic valve is in a closed state at this time, the electromagnetic valve needs to be opened first, so that the air pressures at the two sides of the plate replacing device are balanced.
S110, adjusting the indoor temperature of the building according to the indoor demand temperature.
When the electromagnetic valve is in an open state and the indoor demand temperature is calculated, the indoor temperature of the building is regulated according to the indoor demand temperature, and the specific process is as follows.
For example, when heating is performed by using a steam device in a building, the larger the opening ratio of the primary side electrically operated valve of the board change device of the steam device is, the larger the amount of steam entering the board change device is; the smaller the electric valve is opened, the smaller the steam quantity entering the plate changing equipment is; the plate change equipment can transfer the heat of steam to a pool water pipe of the building so as to supply energy to the building; the opening proportion of the electric valve at the primary side of the plate changing device is adjusted according to the indoor demand temperature, so that the steam quantity of the steam entering the plate changing device is controlled, and the building indoor temperature at the secondary side of the plate changing device is further automatically adjusted. The detailed steps are described in steps S1101 to S1104.
In one possible implementation, as shown in FIG. 3, step S110 includes S1101-S1104.
S1101, inputting the indoor demand temperature into the PID controller, so that the PID controller outputs the stroke percentage, and acquiring the current stroke percentage.
In this embodiment, if the steam device is used to supply heat to the building, the opening ratio of the primary side electric valve of the plate change device is adjusted according to the indoor demand temperature, and the indoor demand temperature can be specifically input into the PID controller first, so that the PID controller can calculate the stroke percentage of the electric valve, and the PID controller is used to calculate the stroke percentage of the device according to the demand temperature. In order to determine whether the electric valve needs to be adjusted, the opening proportion of the primary side electric valve of the current plate changing device needs to be obtained first.
S1102, judging whether the current stroke percentage is equal to the stroke percentage; if not, executing step S1103; if yes, go to step S1104.
