Detailed Description
To make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to fig. 1-2.
The embodiment of the application discloses a building heating and ventilation intelligent control method. The building heating and ventilation intelligent control method can be used for monitoring the air conditioner function of each user in a building and displaying the air conditioner function level, so that the user can determine whether the corresponding maintenance of the air conditioner is needed or not according to the air conditioner function level. The intelligent management method for the building heating and ventilation is implemented by taking heating and ventilation intelligent control equipment as an execution main body and assisting an indoor temperature detection module, an outdoor temperature detection module and a wind speed detection module.
Specifically, the heating and ventilation intelligent control device comprises a processor and a memory, and can also be provided with a touch display screen, the indoor temperature detection module and the outdoor temperature detection module can be temperature sensors, the indoor temperature detection module is used for detecting temperature data in the environment where the air conditioner is located, the outdoor temperature detection module can be used for detecting outdoor temperature data, and the wind speed detection module can be a wind speed sensor or an anemometer and is used for detecting the wind speed of an air outlet of the air conditioner; indoor temperature detection module, outdoor temperature detection module and wind speed detection module all communication connection in warm intelligent control equipment that leads to through warm opening and close of leading to intelligent control equipment control indoor temperature detection module, outdoor temperature detection module and wind speed detection module, and acquire indoor temperature data, outdoor temperature data and wind speed data.
Correspondingly, heating and ventilation intelligent control equipment, an indoor temperature detection module and an air speed detection module which are in communication connection with the heating and ventilation intelligent control equipment can be installed in the environment where the air conditioner of each user in the building is located (namely, in a room where the air conditioner is located), and the heating and ventilation intelligent control equipment is used for controlling the indoor temperature detection module to detect indoor temperature data of the environment where the air conditioner is located; an outdoor temperature detection module is installed on the outdoor wall of each user, and the outdoor temperature detection module is controlled by the heating and ventilation intelligent control equipment to acquire outdoor temperature data.
The specific processing flow of the building heating and ventilation intelligent control method is shown in fig. 1, and the specific processing flow of fig. 1 will be described in detail below with reference to specific embodiments, and the content is as follows:
In implementation, the heating and ventilation intelligent control equipment installed in each user room is in communication connection with the user room air conditioner so as to control the working state of the air conditioner, such as the on-off control of the air conditioner; the heating and ventilation intelligent control equipment is provided with a touch display screen, and a starting button is preset on the touch display screen; when a user needs to start the air conditioner, the starting button is touched, so that an air conditioner starting instruction is triggered, the heating and ventilation intelligent control device controls the air conditioner to start according to the air conditioner starting instruction, the indoor temperature detection module is started to start detecting indoor temperature data in real time, and the indoor temperature detection module sends the detected indoor temperature data to the heating and ventilation intelligent control device.
And 102, when receiving an air conditioner starting instruction, acquiring indoor temperature data detected by an indoor temperature detection module every preset time length from the receiving time of the air conditioner starting instruction, and calculating a temperature change value in each preset time length.
In implementation, when the heating and ventilation intelligent control device receives an air conditioner starting instruction, indoor temperature data detected by the indoor temperature detection module is obtained at intervals of a preset time, and the indoor temperature detection module sent by the indoor temperature detection module at other time is discarded by the heating and ventilation intelligent control device; correspondingly, the indoor temperature data acquired by each heating and ventilation intelligent control device corresponds to an acquisition time, and the difference between adjacent acquisition times is a preset time, wherein the preset time can be specifically 18-20 minutes, because when the outdoor temperature is too low and is as low as zero, the outdoor temperature of the air conditioner installed outdoors is influenced by the outdoor temperature to frost, and in 18 minutes after the air conditioner is started under the condition, the air conditioner is in a defrosting state, namely the change of the indoor temperature by the air conditioner is very slight, so that the indoor temperature data acquired after the first 18 minutes after the air conditioner is started can be defaulted to be the initial indoor temperature at which the air conditioner starts to heat, and the temperature change value in each preset time is calculated, namely the absolute value of the difference between the current acquisition time and the two indoor temperature data corresponding to the previous acquisition time; the temperature change value can reflect a change value of the indoor temperature through the air conditioner, and further reflect the function of the air conditioner according to the size of the change value, for example, the heating and cooling effect of the air conditioner is reflected through the size of the change value, and the larger the change value is, the better the heating and cooling effect is. The acquisition time corresponding to the initial indoor temperature is the first acquisition time, so the initial indoor temperature can be compared with a preset temperature value, the preset temperature value is a preset temperature value in the heating and ventilation intelligent control device and is used for subtracting the initial indoor temperature to obtain a temperature change value, and the preset temperature value can be 0 degree, so the temperature change value corresponding to the initial indoor temperature is also the initial indoor temperature change value, and the judgment of the air-conditioning heat and refrigeration effect is not influenced by the temperature change value corresponding to the initial indoor temperature change value.
And 103, comparing the temperature change value with a preset change reference value, and determining and displaying the air conditioner function grade information according to the comparison result and a preset first corresponding relation table, wherein the first corresponding relation table is used for storing the corresponding comparison result and the air conditioner function grade information corresponding to the comparison result.
In the implementation, the heating and ventilation intelligent control equipment compares the temperature variation value with a preset variation reference value, and the specific comparison mode can be as follows: comparing the difference value of the temperature change value with a preset change reference value; a third corresponding relation table is preset in the heating and ventilation intelligent control device, the third corresponding relation table is shown in table 1, a plurality of temperature intervals and difference value change amplitudes corresponding to the temperature intervals are stored in the third corresponding relation table, the heating and ventilation intelligent control device determines the temperature interval where the difference value between the temperature change value and the preset change reference value is located and the difference value change amplitude of the corresponding temperature interval according to the preset third corresponding relation table, and the comparison result is the difference value change amplitude; the first corresponding relation table is shown in table 2, and is used for storing the comparison result and the corresponding air conditioner skill level information; the heating and ventilation intelligent control equipment determines the air conditioner function grade corresponding to the difference value change amplitude according to the first corresponding relation table, then generates air conditioner function grade information with the air conditioner function grade, and finally displays the air conditioner function grade information on a touch display screen of the heating and ventilation intelligent control equipment so that a user can know the current air conditioner function grade.
In addition, in order to facilitate the user to know the displayed air conditioner function level, the air conditioner function level information may further include an explanation content of the corresponding air conditioner function level, for example, the explanation content corresponding to the "maintenance required level" may be for maintenance required by contacting a maintenance worker; the explanation content corresponding to the good grade can be that the air conditioner has good function and can be maintained properly; the explanation content corresponding to the "excellent grade" may be that the current air conditioner is better, and the maintenance operation is not required.

Optionally, because the air conditioner generally sets the wind speed when operating, the change value of the indoor temperature of the air conditioner when operating according to different wind speeds within the same preset time is different, generally, the larger the wind speed is, the stronger the indoor temperature is, and the larger the change value of the indoor temperature is, therefore, in order to make the determined temperature change value and the function level of the air conditioner more accurate, different change reference values can be respectively set according to the difference of the wind speeds, and a change reference value corresponding to the current wind speed is selected to be compared with the temperature change value, correspondingly, the intelligent control method for building heating ventilation includes the following processing:
the air conditioner starting instruction also comprises wind speed grade information;
the step 103 of comparing the temperature variation value with a preset variation reference value includes:
determining a change reference value corresponding to the wind speed grade information according to the wind speed grade information and a preset second comparison table, wherein the second comparison table is used for storing a corresponding relation between the wind speed grade and the change reference value;
and comparing the temperature change value with a change reference value.
In implementation, a working mode input box is further displayed on the touch display screen of the heating and ventilation intelligent control device, so that a user can define the working mode of the air conditioner, and the working mode can include a wind speed grade, that is, the user can define the wind speed of the air conditioner during working by inputting the wind speed grade in the working mode input box.
The user can input the working mode in the working mode input frame firstly, and then touch the start button to trigger the air conditioner start instruction, the air conditioner start instruction is an instruction automatically generated by the heating and ventilation intelligent control device when the user touches the start button, and the heating and ventilation intelligent control device can add the working mode input by the user in the working mode input frame to the air conditioner start instruction when generating the air conditioner start instruction, and then control the working state of the air conditioner according to the working mode in the air conditioner start instruction. The air speed grade can be specifically expressed as low speed or medium speed or high speed, and the heating and ventilation intelligent control device can adjust the air speed of the air conditioner according to the air speed grade information.
In addition, after the heating and ventilation intelligent control device calculates the temperature change value, the heating and ventilation intelligent control device firstly determines a change reference value corresponding to the current wind speed grade according to the current wind speed grade information and a preset second comparison table, and the wind speed grade and the change reference value corresponding to each wind speed grade are stored in the second comparison table; after the corresponding change reference value is determined, the heating and ventilation intelligent control equipment compares the temperature change value with the corresponding change reference value.
Optionally, if the user wants to adjust the air speed after the air conditioner is operated for a period of time, at this time, the intelligent control method for building heating and ventilation includes the following steps:
receiving and storing wind speed grade information corresponding to an air conditioner starting instruction;
receiving an air conditioning regulation instruction sent by a user, wherein the air conditioning regulation instruction at least comprises air speed regulation information corresponding to the air speed grade information; updating the wind speed grade information content and the air conditioner wind speed according to the wind speed adjusting information;
step 102 comprises:
if an air conditioner starting instruction is received and an air conditioner adjusting instruction is not received, acquiring and storing indoor temperature data detected by an indoor temperature detection module and corresponding acquisition time and air speed grade information every preset time from the receiving time of the air conditioner starting instruction;
if an air conditioner adjusting instruction is received, acquiring and storing indoor temperature data detected by an indoor temperature detection module and corresponding acquisition time and air speed grade information at intervals of preset time from the receiving time of the air conditioner adjusting instruction;
and if the wind speed grade information of the indoor temperature data corresponding to the two adjacent acquisition times is the same, calculating the difference of the two indoor temperature data, namely the temperature change value.
In implementation, when the heating and ventilation intelligent control equipment receives an air conditioner starting instruction, the heating and ventilation intelligent control equipment stores air speed grade information corresponding to the air conditioner starting instruction; when the user touches the adjusting confirming button, the heating and ventilation intelligent control device automatically generates an air conditioner adjusting instruction and adds the content in the working mode input frame to the air conditioner adjusting instruction; and the heating and ventilation intelligent control equipment readjusts the working state of the air conditioner according to the content of the air conditioner adjusting instruction, and replaces the stored wind speed grade of the wind speed grade information with the content of the wind speed adjusting information.
When the temperature change value is calculated, due to the switching of the wind speed, the temperature change value calculated by the indoor temperature data corresponding to the corresponding acquisition time before and after the switching time of the wind speed grades is meaningless, and the change reference value cannot be determined subsequently because the corresponding wind speed grades are different. Therefore, when the heating and ventilation intelligent control device calculates the temperature change value, it is necessary to determine whether the acquisition time corresponding to the two indoor temperature data are adjacent to each other, and also determine whether the wind speed grades corresponding to the two indoor temperature data are the same, and only calculate the temperature difference corresponding to the two indoor temperature data, in which the wind speed grade information is the same and the difference between the acquisition times corresponding to the two indoor temperature data is the preset time length, so as to obtain the temperature change value.
Optionally, the temperature change value may also be affected by the overall spatial volume of the installation environment of the air conditioner installed by the user, and the larger the spatial volume is, the smaller the change value of the temperature of the environment of the air conditioner is. Therefore, the temperature variation value may not be reduced due to the reduced function of the air conditioner itself, or may be reduced due to the larger volume of the space where the air conditioner is located.
