Detailed Description
The present application is described in further detail below with reference to figures 1-4.
The embodiment of the application discloses a central air-conditioning energy-saving control method based on a cloud platform, and the method can be applied to an energy-saving control system. Referring to fig. 1, the energy saving control system includes a server and a plurality of control terminals in signal connection with the server. Each control terminal is correspondingly arranged in one building and used for monitoring and controlling the central air conditioner in the building. Wherein, the building can be a factory, a hospital, a hotel and the like.
The process flow shown in fig. 2 will be described in detail below with reference to the specific embodiments, and the contents may be as follows:
s201: and periodically acquiring monitoring data fed back by the target control terminal, wherein the monitoring data comprises the first indoor real-time temperature.
Wherein, the target control terminal may be any one of all control terminals.
In implementation, the server may send a monitoring data obtaining request to the target control terminal according to a preset detection period, for example, once every 2 hours, once every 3 hours, and so on, so that the target control terminal feeds back the detected monitoring data to the server. The monitoring data comprises a first indoor real-time temperature, and the target control terminal can control a plurality of temperature sensors which are arranged in the building in advance to perform primary temperature detection after receiving the monitoring data acquisition request. Then, the target control terminal can calculate the first indoor real-time temperature based on all temperature detection results.
S202: and when the temperature difference between the calculated first indoor real-time temperature and the pre-stored optimal room temperature is greater than a preset minimum difference, taking the temperature difference as a target temperature variation.
In an implementation, the server may calculate a temperature difference between the real-time indoor temperature and a pre-stored optimal indoor temperature, and compare the temperature difference with a preset minimum difference. When the temperature difference is less than the minimum difference, it means that the indoor temperature does not need to be adjusted, i.e., the central air conditioner does not need to be used. When the temperature difference is larger than the minimum difference, the server takes the temperature difference as the target temperature variation. Wherein, the optimal room temperature can be automatically switched based on different seasons.
S203: and confirming the current target refrigerating capacity corresponding to the target temperature variation based on the target temperature variation and the corresponding relation between the temperature variation corresponding to the target control terminal and the refrigerating capacity which is stored in advance.
The server is pre-stored with a plurality of refrigerating capacity reference tables corresponding to different control terminals. The refrigerating capacity reference table records the corresponding relation between the temperature variation and the refrigerating capacity. Generally, the cooling capacity = unit area cooling capacity × cooling area, because the buildings corresponding to different control terminals are different, the cooling areas required by the central air conditioners are also different, and the unit area cooling capacity is related to the specific building materials in the buildings, the building environment, and the temperature of the environment. The working personnel can calculate theoretical refrigerating capacities of the central air conditioners corresponding to different control terminals under different temperature variation conditions in advance based on refrigerating areas corresponding to the control terminals, namely refrigerating areas required to be served by the corresponding central air conditioners and refrigerating capacities per unit area under different area ambient temperatures, and input the theoretical refrigerating capacities into the server, so that the refrigerating capacities corresponding to the different control terminals are pre-stored in the server according to the refrigerating capacity reference tables. For some suitable indoor temperatures, the corresponding refrigerating capacity can be 0, which means that the central air conditioner is not needed for temperature adjustment.
In implementation, the server may extract the corresponding current target cooling capacity from the cooling capacity reference table corresponding to the target control terminal based on the obtained target temperature variation.
S204: and sending the current target refrigerating capacity to a target control terminal so that the target control terminal controls the running state of the corresponding central air conditioner based on the current target refrigerating capacity.
In implementation, the server sends the extracted current target refrigerating capacity to the target control terminal, so that the target control terminal can control the running state of the central air conditioner based on the current target refrigerating capacity, and the temperature in the building is adjusted to be a proper value.
Optionally, in another embodiment, after the above S204, the following may be further included:
and after the preset waiting time, acquiring the second indoor real-time temperature fed back by the target control terminal.
The waiting time is set to fully realize the refrigeration effect of the central air conditioner corresponding to the target control terminal.
In implementation, after a preset waiting time, the server may send an indoor temperature detection request to the target control terminal, so that the target control terminal controls a plurality of connected temperature sensors arranged in the building to complete one temperature detection. And then, the target control terminal can calculate the second indoor real-time temperature based on all temperature detection results and feed back the second indoor real-time temperature to the server.
And calculating to obtain an actual temperature change value based on the first indoor real-time temperature and the second indoor real-time temperature.
In an implementation, the server may calculate a difference between the first indoor real-time temperature and the second indoor real-time temperature, so as to obtain an actual temperature change value.
A first deviation value between the actual temperature change value and the target temperature change amount is calculated.
In an implementation, the server may calculate a difference between the actual temperature variation value and the target temperature variation value, and define the difference as a first deviation value, where the first deviation value represents that the output power of the central air conditioner is too large when the first deviation value is a positive number, and represents that the output power of the central air conditioner is too small when the first deviation value is a negative number.
And when the first deviation value is larger than a preset temperature difference threshold value, generating a parameter calibration instruction carrying a refrigerating capacity calibration value based on the first deviation value.
In implementation, the server may compare the first deviation value with a temperature difference threshold value stored in advance, and when the first deviation value is greater than the preset temperature difference threshold value, it represents that the temperature adjustment effect of the central air conditioner is not in line with the expectation, and at this time, the server may further generate a parameter calibration instruction carrying the refrigeration capacity calibration value based on the first deviation value.
And sending the parameter calibration instruction to a target control terminal so that the target control terminal adjusts the running state of the corresponding central air conditioner based on the refrigerating capacity calibration value carried in the parameter calibration instruction.
In implementation, the server may send the generated parameter calibration instruction to the target control terminal, so that the target control terminal adjusts the operation state of the corresponding central air conditioner based on the refrigeration capacity calibration value carried in the parameter calibration instruction, thereby making the final indoor temperature as close to the optimal temperature as possible.
Optionally, in another embodiment, the monitoring data further includes a total power consumption amount of the central air conditioner corresponding to the target control terminal in a single period in the previous period. The total power consumption of a single period refers to the total power consumption of the central air conditioner corresponding to the target control terminal in the previous period. In this case, after the above S201, the following may be further included:
and identifying the historical target refrigerating capacity of the target control terminal in the last period.
The historical target refrigerating capacity refers to the current target refrigerating capacity which is identified in the last period.
In implementation, the server may identify, from stored data, a historical target cooling capacity of the target control terminal in a previous cycle.
And identifying the theoretical total power consumption corresponding to the historical target refrigerating capacity based on the prestored corresponding relationship between the refrigerating capacity corresponding to the target control terminal and the theoretical total power consumption.
The server is stored with a plurality of theoretical total power consumption reference tables corresponding to different control terminals in advance, and the theoretical total power consumption reference tables record the corresponding relation between the refrigerating capacity and the theoretical total power consumption. Since the specifications of the central air conditioners corresponding to different control terminals are different, the power consumption levels are also different. The theoretical total power consumption refers to the total power consumption generated by the corresponding central air conditioner continuously operating in one period.
In implementation, the server may identify a theoretical total power consumption amount corresponding to the historical target cooling capacity based on the theoretical total power consumption amount reference table corresponding to the target control terminal.
And when the difference between the single-cycle power consumption total amount and the corresponding theoretical power consumption total amount is larger than a preset power consumption difference threshold value, adding a fault prompt label for the central air conditioner corresponding to the target control terminal, and sending a fault prompt signal to the user terminal associated with the target control terminal.
In implementation, the server may compare the total power consumption amount of the single period fed back by the target control terminal with the theoretical total power consumption amount of the central air conditioner corresponding to the target control terminal in the single period, and when a difference between the two is greater than a preset power consumption difference threshold, it represents that the actual output power is far greater than or far less than the supposed output power when the central air conditioner operates in the previous period. At this time, the server may determine that the central air conditioner corresponding to the target control terminal may have a fault, and add a fault prompt tag to the central air conditioner. Meanwhile, the server also sends a fault prompt signal to the user terminal associated with the target control terminal. The user terminal related to the target control terminal is a device such as a mobile phone and a tablet of a manager corresponding to the target control terminal, and the user terminal is helpful for reminding the manager of maintaining and troubleshooting the central air conditioner in time by sending a fault prompt signal to the user terminal.
Optionally, in another embodiment, after the step S204, the following process may be further included:
and if the fault prompt tag is added to the target control terminal, sending a real-time monitoring request to the target control terminal so that the target control terminal can continuously acquire and feed back real-time detection data of the corresponding central air conditioner within a preset detection time.
The real-time detection data may include power consumption of a system power supply in a host of the central air conditioner, temperature in a machine room, operating current of a compressor and temperature of a compressor body, temperature and humidity in a fresh air pipeline, and the like.
In implementation, after recognizing that the fault prompt tag is added to the target control terminal, the server may send a real-time monitoring request to the target control terminal in order to further confirm whether the target control terminal really has a fault, so that the target control terminal continuously obtains real-time detection data of the corresponding central air conditioner within a preset detection duration and feeds the real-time detection data back to the server.
And identifying whether abnormal data exist in the real-time detection data.
In implementation, the server may compare the real-time detection data with corresponding pre-stored standard data, so as to determine whether there is abnormal data in the real-time detection data.
And if so, judging the fault type of the central air conditioner corresponding to the target control terminal based on the data type of the abnormal data.
In implementation, after the server determines that the abnormal data occurs in the real-time detection data, the server may determine the fault type of the central air conditioner corresponding to the target control terminal based on the data type of the abnormal data and the pre-stored correspondence between the fault type and the abnormal data type.
And sending a fault notification carrying the fault type to a user terminal associated with the target control terminal.
In implementation, the server may generate a fault notification carrying the determined fault type, and send the fault notification to the user terminal associated with the target control terminal, so that a manager carrying the user terminal can confirm the fault type of the central air conditioner in time, and the fault processing efficiency can be improved.
Optionally, in another embodiment, in order to further improve the efficiency of processing the fault, after the fault notification carrying the fault type is sent to the user terminal associated with the target control terminal, the following may be further included:
and after receiving a maintenance request signal fed back by a user terminal related to the target control terminal, sending a maintenance notice to a preset maintenance center, wherein the maintenance notice carries the actual address of the target control terminal and the identified fault type.
The maintenance center may be an after-sales store of the central air conditioner or a maintenance store approved by a manager.
In implementation, the sent fault notification may also carry a jump link, and a manager may feed back a maintenance request signal to the server by clicking the jump link in the user terminal. After receiving the maintenance request signal, the server may send a maintenance notification to a preset maintenance center, where the maintenance notification carries the actual address of the building corresponding to the target control terminal and the corresponding fault type identified in the above step, so that the maintenance center can arrange the home maintenance conveniently.
Optionally, in another embodiment, after the calculating the actual temperature variation value based on the first indoor real-time temperature and the second indoor real-time temperature, the method may further include the following steps:
and generating and storing a temperature change record corresponding to the target control terminal, wherein the temperature change record records the corresponding relation between the actual temperature change value and the current target refrigerating capacity.
In implementation, after the actual temperature change value is obtained through calculation each time, the server generates and stores a temperature change record corresponding to the target control terminal, and the temperature change record records the corresponding relation between the actual temperature change value and the current target refrigerating capacity.
In this case, the method may further include the following:
and extracting all temperature change records which are stored in a preset historical time and correspond to the target control terminal from a preset statistical time node.
The statistical time node can be preset by a worker, and the time interval between adjacent statistical time nodes can be 3 months, 6 months and the like. The length of the preset historical duration may be equal to the time interval of the adjacent statistical time nodes.
In implementation, the server may extract all temperature change records corresponding to the target control terminal, which are completely stored within a preset historical time length, at each statistical time node.
And updating the stored corresponding relation between the refrigerating capacity and the temperature variation corresponding to the target control terminal based on all the extracted temperature variation records.
In implementation, the server may identify all the extracted temperature change records, average all the actual temperature change values corresponding to the current target cooling capacity with the same value, and update the temperature change amount in the correspondence relationship between the cooling capacity and the temperature change amount corresponding to the target control terminal based on the calculation result. Therefore, the accuracy of the corresponding relation between the temperature variation and the refrigerating capacity is improved.
