Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The heating and ventilation pipeline information extraction method can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 may obtain spatial information of a space to be extracted from the server 104, the terminal 102 may obtain load information of the space to be extracted within a preset time according to the obtained spatial information and a preset load calculation function, and obtain device flow information corresponding to a heating and ventilation pipeline in the space to be extracted according to the load information, so that feature information of the heating and ventilation pipeline may be obtained according to the device flow information and the load information. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, and tablet computers, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, a method for extracting heating and ventilation pipeline information is provided, which is described by taking the method as an example of being applied to the terminal in fig. 1, and includes the following steps:
step S202, acquiring spatial information of a space to be extracted; the space information includes configuration information of a space to be extracted and environment information.
The space to be extracted may be a space in which heating and ventilation pipeline information extraction is required, specifically, a room, and the end device specifically corresponding to the heating and ventilation pipeline in the current building may be an air conditioner, and the air conditioner is usually installed in the room. When the characteristics of the heating ventilation pipeline are extracted, the information of the space served by the heating ventilation pipeline needs to be extracted, so that the terminal 102 can acquire the space information of the space to be extracted, that is, the space information in the room, including the configuration information and the environment information of the room. The configuration information may be related information such as spatial configuration data of the space to be extracted, for example, room configuration data in a room; the environmental information may be information such as an environmental object included in the space to be extracted, for example, an article or a living being in a room, the terminal 102 may obtain the spatial information from the server 104, that is, the server 104 may store spatial information of a plurality of spaces to be extracted, and the terminal 102 may also perform data acquisition on the space to be extracted in real time, so as to obtain the spatial information.
And step S204, acquiring load information of the space to be extracted within preset time according to the space information and a preset load calculation function.
The spatial information may be information corresponding to a space to be extracted, which is acquired by the terminal 102, and includes configuration information, environmental information, and the like; the preset load calculation function may be a function for calculating a load of the above-described space to be extracted, that is, load information of a room may be calculated. Because the spatial information in the room is different and the cooling capacities provided by the heating and ventilation pipelines required at different times are different, the terminal 102 needs to calculate the loads of different spaces to be extracted in the preset time for the heating and ventilation pipeline, and the terminal 102 can obtain the load information of the space to be extracted in the preset time according to the spatial information and a preset load calculation function, specifically, the terminal 102 can input the spatial information into the preset load calculation function, and the preset load calculation function can obtain the load information of the space to be extracted, namely, the room corresponding to the spatial information, in the preset time according to the spatial information. The preset load calculation function may be a function provided by preset load calculation software, for example, a year-round load calculation function, and the terminal 102 may input the spatial information into the year-round load calculation software, so that the load of the space to be extracted within the preset time, for example, within one day, that is, within 24 hours, is calculated according to the spatial information in the year-round load calculation software, specifically, the preset load calculation function may obtain data corresponding to each room according to configuration information and environmental information in the spatial information, and determine, based on the data, loads required by the heating and ventilation pipeline to refrigerate the room within different times, so as to form corresponding load information as an output result. The preset load calculation function may be formed by a single function or a function group formed by a plurality of functions.
And step S206, acquiring equipment flow information corresponding to the heating and ventilation pipeline in the space to be extracted according to the load information.
The load information may be information calculated by the preset load calculation function according to the spatial information of the space to be extracted. The terminal 102 may obtain the device flow information corresponding to the heating and ventilation pipeline in the space to be extracted according to the load information, and specifically, the terminal 102 may perform intra-distribution on the obtained load information according to different rooms, and then obtain the device flow information corresponding to the load information in the preset time through a preset calculation function according to the load information in the preset time. The device flow information can be a water pipe of a heating and ventilation pipeline, the water pipe can be used for transmitting cold water, and the cold water flow required to be transmitted by different load information can be different.
And step S208, obtaining the characteristic information of the heating and ventilation pipeline according to the equipment flow information and the load information.
The device flow information may be flow information in a water pipe of the heating and ventilation pipeline, the load information may be load information of the space to be extracted, which is calculated based on the preset load calculation function, the terminal 102 may obtain characteristic information of the heating and ventilation pipeline according to the device flow information and the load information, specifically, both the device flow information and the load information may be information within a preset time, for example, within 24 hours, and the terminal 102 may extract the device flow information and the load information within the preset time and perform corresponding processing on the load information, for example, extract a specific information, for example, resistance information, from the load information, and use the device flow information and the resistance information as the characteristic information of the heating and ventilation pipeline.
In addition, after the terminal 102 extracts the characteristic information of the heating and ventilation pipeline, a corresponding characteristic information change map may be formed according to the characteristic information, that is, resistance information and equipment flow information within a preset time, specifically, as shown in fig. 3, fig. 3 is an interface schematic diagram of the heating and ventilation pipeline characteristic information in an embodiment. The abscissa may be the device flow information, the ordinate may be the resistance information, and both the device flow information and the resistance information may be information within a preset time. As can be seen from fig. 3, since the cooling capacities of different rooms required at different times are different, the cooling capacity transmits cold water to the end equipment in the room, such as air conditioning equipment, through the water pipe in the heating and ventilation pipeline, so as to provide cold air, and therefore the flow rate in the water pipe changes due to the change of the cooling capacity required by the room, and thus there is a change diagram shown in fig. 3.
According to the method for extracting the information of the heating and ventilation pipeline, space information including configuration information and environment information of a space to be extracted is obtained, then load information of the space to be extracted within preset time is obtained according to the space information and a preset load calculation function, equipment flow information corresponding to the heating and ventilation pipeline in the space to be extracted is obtained according to the load information, and then characteristic information of the heating and ventilation pipeline is extracted according to the equipment flow information and the load information. Compared with the traditional method for estimating the water path curve of the heating and ventilation system, the method has the advantages that the space information of the space to be extracted is obtained, the load information is obtained by utilizing the space information and the preset load function, the equipment flow information is obtained according to the load information, and finally the characteristic information of the heating and ventilation pipeline is obtained according to the equipment flow information and the load information.

The terminal 102 may further obtain at least one of composition structure information and object information of the space to be extracted, as the environment information, wherein the composition structure information may be composition information in the room, such as the position, number, size, and the like of a door, a window, and the object information may be object information in the room, such as the number of people or animals in the room, and the number and position of items in the room, and the like.

In addition, in the step of inputting the spatial information into the preset load calculation function, the terminal 102 may input the re-encoded spatial information into the preset load calculation function after re-encoding the spatial information, so that the preset load calculation function performs load information calculation on the re-encoded spatial information.
