[0023] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will further describe the present invention in detail with reference to the accompanying drawings and specific implementation manners.
[0024] Figure 1 Device interaction terminal module diagram provided by the embodiment of the present invention, as Figure 1 shown, the present invention provides a device interaction terminal, which is characterized by including: a core processing module 1 and a data storage module 2, a data acquisition module 5, a data upload module 6, an interactive display module 4, and an interface expansion module 3 that are respectively connected to the core processing module 1; the core processing module 1 includes: an ARM processor; the data storage module 2 includes: a memory sub-module and a flash sub-module;
[0025] The memory sub-module is used to temporarily store the operation data of the core processing module 1 and the original acquisition data of the data acquisition module 5; the flash memory sub-module is used to store the operating system files, interactive configuration project files, data preprocessing algorithm files, and the data files processed by the ARM processor; the data acquisition module 5 is used to communicate with a preset acquisition terminal, send intelligent interaction instructions to the acquisition terminal, and use the acquisition terminal to perform real-time acquisition on the target object to obtain the original acquisition data; the data upload module 6 is used to upload the data files processed by the ARM processor to the cloud server and transmit the instructions sent by the cloud server to the ARM processor; the interactive display module 4 is used to display the interactive configuration project files and collect touch feedback signals in real time; the interface expansion module 3 is used to connect the RS-485 bus interface, network cable interface, WiFi interface, power interface, sim card interface, and USB interface to the core processing module 1.
[0026] Further, the preprocessing modes of the core processing module 1 include: data unit conversion mode, fault word parsing mode, data change upload detection mode, and virtual point calculation mode.
[0027] Preferably, the conversion formula of the data unit conversion mode is: Bv = Av * k; where Bv represents the result after conversion; Av represents the original data value; k represents the conversion coefficient.
[0028] Specifically, the fault word parsing formula of the fault word parsing mode is: bits[i] = (word >> i) &; where word >> i represents the target parsing data shifted to the right by i bits; & represents the bitwise AND operation; bits[i] represents storing the parsing result in the i-th position of the bits array.
[0029] Further, the virtual point calculation mode includes: temperature efficiency calculation sub-mode, heat pump COP calculation sub-mode, and fresh / supply air ratio calculation sub-mode.
[0030] Specifically, the temperature efficiency calculation formula of the temperature efficiency calculation sub-mode is: (Q / ΔT) ÷ (m x c); where Q is the heat transfer amount; ΔT is the temperature difference; m is the fluid mass; c is the specific heat capacity of the fluid.
[0031] Preferably, the heat pump COP calculation formula of the heat pump COP calculation sub-mode is: (T + 273) / △t; where T is the ambient temperature; △t is the temperature rise.
[0032] Specifically, the fresh / supply air ratio calculation formula of the fresh / supply air ratio calculation sub-mode is: n * V / (QS / Cp); where n is the room air change rate; V is the room volume; QS is the sensible heat; Cp is the specific heat of air.
[0033] Preferably, the core processing module 1 retrieves the data preprocessing algorithm file stored in the flash memory module of the data storage module and performs arithmetic processing on the original collected data stored in the memory module, and stores the preprocessed data back into the flash memory module of the data storage module.
[0034] Specifically, there are four data preprocessing modes in this embodiment as follows:
[0035] 1) Data unit conversion: Data unit conversion, such as the conversion of temperature units from Fahrenheit to Celsius, the conversion of pressure units from Pascal to bar, etc., reduces the computing pressure on the server.
[0036] Conversion formula:
[0037] Bv = Av * k
[0038] The fault points of the device are usually represented by bit (0 / 1), but in communication, they are usually transmitted in the form of fault words (word). This preprocessing can parse the fault words and directly upload the corresponding fault point information, reducing the computing pressure on the server.
[0039] 2) Fault word parsing formula:
[0040] bits[i] = (word >> i) & 1
[0041] 3) Detection of data change upload: By saving the results of the previous data collection and comparing them with the results of the current data collection, if the data at the point is the same, the data is not uploaded, reducing the consumption of data traffic.
[0042] 4) Virtual point calculation: By completing the relevant calculations of virtual points on the intelligent terminal, such as the calculation of the temperature efficiency of the heat exchanger, the calculation of the heat pump COP, the calculation of the fresh / supply air ratio of the room, etc., the pressure on the server is reduced.
[0043] Furthermore, the interaction display module 4 retrieves the interactive configuration engineering file stored in the flash memory module of the data storage module, maps the display screen to the touch screen, and retrieves the preprocessed data stored in the flash memory module of the data storage module to update the display content on the screen in real time. At the same time, it collects the touch feedback signals of the screen in real time and feeds them back to the core processing module 1. The data upload module 6 retrieves the preprocessed data stored in the flash memory module of the data storage module and sends it to the server through the interface expansion module 3. The interface expansion module 3 is used to complete the connection of physical interfaces such as RS-485 bus interface, network cable interface, WiFi interface, power interface, sim card interface and USB interface with the core processing module 1.
[0044] Preferably, this embodiment combines the data acquisition function of the gateway with the interaction function of the local interaction device, saving the overall cost and floor space of the device, reducing the maintenance operation of the device, and having the data preprocessing ability, reducing the data processing pressure on the server side. It solves the problems of cumbersome device maintenance operations, large traffic consumption and processing pressure on the server side proposed in the background problem.
[0045] Reference Figure 2 , the data preprocessing process includes: after the original data is collected, it is judged whether data preprocessing is required according to the preset parameters. If it is required, the corresponding preprocessing operation is carried out. If it is not required, it is judged whether change upload is required according to the preset parameters. If it is required, it is judged whether the data has changed. If the data has changed, the upload operation is carried out. If there is no change, it directly ends. If the change upload detection is not required, the data upload operation is directly carried out.
[0046] The beneficial effects of the present invention are as follows:
[0047] Through the data acquisition module and the interactive display module, the present invention avoids the problem of manually modifying the acquisition device and the interactive device when the device parameter points change, simplifying the operation difficulty; through the data storage module and the data acquisition module, the preprocessing of the acquired data is realized, reducing the server pressure.
