DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0051] like Figure 1-Figure 3 As shown, an IoT collection device based on edge computing, the IoT collection device 100 includes a temperature and humidity sensor module 10, a control processing terminal module 20, an edge computing module 30, a regulator 40 and a control panel display screen 50. Among them,

[0052] The temperature and humidity sensor module 10 is used to collect temperature and humidity data of the target environment; the control processing terminal module 20 is connected to the edge computing module 30 for communication, receives temperature and humidity data, and obtains control instructions according to the algorithm analysis of the edge computing module 30 to adjust the operation mode of the temperature and humidity control device; the edge computing module 30 is connected to the temperature and humidity sensor module 10, receives and stores temperature and humidity data, and feeds back command signals and the control strategy of the temperature and humidity control device to the control processing terminal module 20 through the edge computing results of the temperature and humidity data collected by the temperature and humidity sensor module 10; the regulator 40 is composed of at least one element that performs physical operations, is connected to the control processing terminal module 20, manually adjusts the working parameters of the temperature and humidity control device, and executes the temperature and humidity control strategy, which adds emergency control measures to deal with special circumstances where automatic control cannot achieve the effect, thereby improving the stability of the equipment; the control panel display screen 50 is used to display data and status monitoring. The parameters of the Internet of Things acquisition device 100 can be set through the control panel display screen 50, which is convenient for the staff to monitor and inspect the status of the equipment.

[0053] The IoT collection device 100 is protected by a shell, and mounting holes are provided at the four corners of the shell. The IoT collection device 100 can be installed on a structure in the collection environment using screws and other fixings.

[0054] The shell is divided into a detection cabin 11, an electrical cabin 12 and a power supply cabin 13. The electrical cabin 12 and the power supply cabin 13 are arranged adjacent to each other and are located on one side of the detection cabin 11. A temperature and humidity sensor module 10 is arranged in the detection cabin 11, a control processing terminal module 20 and an edge computing module 30 are arranged in the electrical cabin 12, and a storage battery for providing electrical energy to the equipment in the detection cabin 11 and the electrical cabin 12 is arranged in the power supply cabin 13; a regulator 40 and a control panel display 50 are arranged on the upper end surface of the electrical cabin 12, and the end surfaces on which the regulator 40 and the control panel display 50 are arranged are inclined surfaces, which are convenient for operation and observation by operators.

[0055] A communication port 18 is provided on the outer side of the electrical compartment 12, and the communication port 18 is connected to the control processing terminal module 20. A communication data cable is used to establish a command control connection between the IoT acquisition device 100 and the temperature and humidity adjustment device through the communication port 18; the communication port 18 includes an Ethernet port, a serial interface and a 4G interface. Specifically, the preferred settings in this embodiment are: 2 100M / 10M Ethernet ports, supporting AUTO MDI / MDIX dual-stage lightning protection; 4 RS485 / 232 serial ports, supporting AUTO MDI / MDIX dual-stage lightning protection; 1 4G interface, supporting SIM card type: Micro SIM card. Supports but is not limited to MQTT, TCP Modbus, Modbus RTU, 645, 104 and custom protocols and other acquisition protocols. In debugging mode, the IoT acquisition device 100 can be remotely maintained through the Internet without relying on the local computer. It supports simulating terminal equipment to reply to the control processing terminal module 20 (ECC) to call for testing and issue control commands. It can also forward the data of the IoT collection device 100 to a third-party platform and accept control instructions from the third-party platform.

[0056] In order to facilitate the maintenance and repair of the temperature and humidity sensor module 10, in this embodiment, the temperature and humidity sensor module 10 is connected and installed with the IoT collection device 100 in a detachable manner. In general, the temperature and humidity sensor module 10 is installed in the detection cabin 11.

[0057] like Figure 4-Figure 6 As shown, specifically, the detection chamber 11 includes an upper cover 111 and a lower base plate 112. The upper cover 111 is sealed on all sides and the upper end face, and the lower end face is an open box structure. The lower end of the upper cover 111 is snap-fitted onto the lower base plate 112, and a plurality of air vents 113 are arranged on both sides and the front side of the upper cover 111 in the direction of the center axis of the end face. The gas in the target environment slowly and naturally enters the detection chamber 11 through the air vents 113, and is thus detected and collected by the temperature and humidity sensor module 10 in the detection chamber 11, thereby reducing the impact of external human factors on the air environment, which causes the special situation that the collected data does not match the real-time environmental temperature and humidity on site.

[0058] The lower substrate 112 is installed on the shell of the Internet of Things acquisition device 100, and at least three accommodating holes 114 are arranged on the lower substrate 112; card slots 115 are arranged on both sides of the accommodating hole 114, and a card connector 116 is arranged in the box body of the upper cover 111 in the direction corresponding to the card slot 115, and the card connector 116 is card-connected and installed on the card slot 115; the upper cover 111 and the lower substrate 112 can be easily opened and buckled. On the one hand, the upper cover 111 protects the temperature and humidity sensor module 10, and on the other hand, this arrangement does not affect the temperature and humidity sensor module 10 to collect the ambient temperature and humidity, and is convenient for daily maintenance and replacement.

[0059] The lower end of each accommodating hole 114 is provided with a base groove 14 for installing the temperature and humidity sensor module 10. The base groove 14 is installed on the lower end surface of the lower substrate 112 through a plate 117. An electrical base 15 is fixedly arranged at the lower part of the base groove 14. The bottom of the detection probe 19 of the temperature and humidity sensor module 10 is a connecting base 16. The connecting base 16 is detachably installed in the base groove 14. The detection probe 19 is connected to the wiring terminal 17 in the middle of the electrical base 15. The electrical base 15 is connected to the control processing terminal module 20 and the edge computing module 30 in a wired manner.

[0060] The temperature and humidity sensor module 10 includes a temperature sensor and a humidity sensor. The temperature sensor and the humidity sensor are arranged in the detection probe 19. The detection probe 19 is covered with a protective cover with a hollow portion. The temperature sensor and the humidity sensor are alternately arranged in the base groove 14. For example, when only three temperature and humidity sensor modules 10 are arranged, Figure 3 As shown, the middle one is the detection probe 19 of the humidity sensor, and the two on both sides are the detection probes 19 of the temperature sensor. Because the detection and adjustment of temperature and humidity pay more attention to the collection and control of temperature, when the number of temperature and humidity sensor modules 10 is small, ensure that the number of temperature sensors is greater than the number of humidity sensors to increase the accuracy of ambient temperature collection.

[0061] The control processing terminal module 20 in this embodiment is also configured with a communication gateway, which supports but is not limited to communication with the superior via protocols such as 104, http, and MQTT; for example, the authentication of the IoT collection device 100 is completed via http, and according to the authentication result, the IoT collection device 100 is accessed and deleted via the MQTT protocol according to the device model specified by the background monitoring and management platform, thereby realizing the integration of the background monitoring and management platform terminal and the internal and external network penetration function. The control processing terminal module 20 periodically reports the IoT collection device 100 status information and the collection and control data information to the background monitoring and management platform in the form of log storage through the communication gateway, and supports the command response of the background monitoring and management platform's active query.

[0062] The present invention deploys an IoT collection terminal in the target area, deploys data collection devices such as temperature and humidity sensors to the collection site through IoT technology, collects the ambient temperature and humidity, and directly connects the IoT collection terminal to the network edge computing module, thereby enabling fast and low-cost monitoring of the on-site ambient temperature and humidity and controlling the working status of the temperature and humidity regulating equipment.

[0063] In specific application scenarios, how to control the operation of temperature and humidity control equipment based on ambient temperature monitoring to achieve the purpose of temperature and humidity control and energy saving requires first using the acquisition terminal to continuously monitor the environment and transmit the original temperature data to the edge side for analysis and calculation in a timely manner. Then, with the help of the intelligent decision-making system, the working mode, target temperature and corresponding adjustment threshold of the temperature and humidity control equipment are automatically or manually set to meet the required indoor heat and humidity exchange intensity under the change of personnel density in different time periods. Finally, combined with the powerful data analysis and computing capabilities of edge computing, the control results are fed back to guide the actual operation of the temperature and humidity control equipment, such as whether to start the temperature and humidity control equipment, the intensity and time of the start-up, etc., to help the temperature and humidity control equipment achieve the purpose of precise temperature control and intelligent management, while ensuring the use needs and reducing energy consumption costs and environmental burdens.

[0064] Therefore, based on the above principles and the IoT collection device 100, a collection method of the IoT collection device based on edge computing is proposed in this embodiment, which is used to collect ambient temperature and humidity, and formulate a temperature and humidity control strategy based on the collected temperature and humidity data. Specifically, the method includes the following steps:

[0065] Step 1: Acquire real-time temperature and humidity data of the collection environment through the temperature and humidity sensor module 10. The specific method is as follows:

[0066] Deploy the IoT collection device 100 to the target area environment, and establish a data information transmission connection between the IoT collection device 100 and the background monitoring platform;

[0067] The temperature and humidity sensor module 10 continuously monitors the real-time temperature and humidity of the target area environment, and transmits the real-time temperature and humidity data to the control processing terminal module 20 and the edge computing module 30 via the network in real time;

[0068] The edge computing module 30 records the time and date of receiving the real-time temperature and humidity data, removes abnormal data that interferes with monitoring, and retains valid temperature and humidity data T 实 .

[0069] Step 2: Based on the comparison between the real-time temperature and humidity data and the preset temperature and humidity data range, adjust the temperature and humidity setting value T of the temperature and humidity control device. p , to achieve temperature and humidity balance control, including the following:

[0070] Preset the lower limit of temperature and humidity T within the target area environment range 下 And the upper limit of temperature and humidity T 上 ;

[0071] The effective temperature and humidity data T 实 And the lower limit of temperature and humidity T 下 And the upper limit of temperature and humidity T上 Compare and judge the temperature and humidity data T 实 Is it within the lower limit of temperature and humidity T? 下 And the upper limit of temperature and humidity T 上 If not, then based on the comparison result, adjust the set temperature and humidity setting value T in the following way p :

[0072] If the temperature and humidity setting value is T p >Temperature and humidity upper limit T 上 , then adjust the temperature and humidity setting value T p Equal to the upper limit of temperature and humidity T 上 ; If the temperature and humidity setting value T p <Temperature and humidity upper limit T 上 , then adjust the temperature and humidity setting value T p Equal to the lower limit of temperature and humidity T 下 .

[0073] Step three, analyze and process the data through the edge computing module 30, determine the optimization strategy for energy saving and emission reduction, form a feedback command signal and send it to the control and processing terminal module 20 to control the temperature and humidity adjustment equipment to implement energy saving and emission reduction measures.

[0074] The edge computing module 30 analyzes and processes the data to determine the optimization strategy for energy conservation and emission reduction in the following manner:

[0075] Set the current temperature and humidity deviation E(T) = |T 实 -T P |;

[0076] Based on the energy consumption E of the current temperature and humidity control equipment e And the current temperature and humidity deviation E(T), calculate the efficiency index of the temperature and humidity adjustment equipment

[0077] Determine the target threshold E for energy conservation and emission reduction thr , judging efficiency index P>E thr ;

[0078] If it is not satisfied, adjust the energy consumption settings of the temperature and humidity control equipment to reduce energy consumption E e And recalculate the efficiency index P.

[0079] In this embodiment, it is also proposed to adjust the energy consumption setting of the temperature and humidity adjustment device, and the method includes the following:

[0080] Calculate target energy consumption E target , assuming that the temperature and humidity data T 实 and temperature and humidity set value T p The larger the difference ΔT is, the higher the power required for temperature and humidity adjustment. Where a, b, c are constants;

[0081] Based on target energy consumption E target , calculate the deviation between actual energy consumption and expected energy consumption B(e) = E t -E target ,

[0082] If the deviation B(e) exceeds the threshold, the power consumption of the temperature and humidity regulating equipment is reduced to meet the energy saving target, and control information is fed back to the control processing terminal module 20 to update the difference ΔT so that the deviation B(e) value is minimized.

[0083] In order to achieve the best effect of the optimization strategy for energy conservation and emission reduction, this embodiment also optimizes and amends the optimization strategy for energy conservation and emission reduction during the implementation of the optimization strategy for energy conservation and emission reduction. The process is as follows:

[0084] First, define the temperature and humidity correction function

[0085] Among them, T p is the set value of temperature and humidity, E t is the current actual energy consumption, E target represents the target energy consumption; k and δ are predefined correction coefficients;

[0086] Then, based on the modified temperature and humidity setting value F, a feedback control signal is output to the control processing terminal module 20: if F>0, the temperature and humidity setting value T is increased. p ; If F≤0, maintain the current operating status of the temperature and humidity control equipment.

[0087] This embodiment uses a network edge computing module close to the data source to process and analyze the collected real-time ambient temperature and humidity data, and feeds back the control strategy of the temperature and humidity regulating equipment to the control processing terminal to achieve balanced control of the ambient temperature and humidity, achieve energy conservation and emission reduction effects, and efficiently utilize electricity resources.
