Description

Technical Field

[0001] The present invention relates to the field of urban centralized heating, and more specifically to a calibration device for online monitoring equipment of indoor air temperature (hereinafter referred to as room temperature). Background Art

[0002] Online room temperature monitoring refers to a temperature measurement method that uses a digital thermometer installed in the indoor space of a building to continuously and automatically measure the room temperature, and transmits the measured room temperature data to the host computer management system through communication equipment for display and monitoring by management personnel.

[0003] Online room temperature monitoring equipment, such as switch-type devices, is an advanced IoT sensor that combines a light switch with a digital thermometer. By replacing an ordinary light switch within a building, it provides room temperature measurement points and a working power source, enabling continuous and automatic room temperature measurement. The measured data is then uploaded to a host computer management system for use.

[0004] Online room temperature monitoring has always suffered from low measurement accuracy. This drawback is primarily due to the fact that most monitoring devices use their installation location as the room temperature measurement point. Due to objective limitations, the installation location of these monitoring devices cannot be standardized or unified, resulting in large errors in temperature sampling. Central heating in my country primarily utilizes two cooling systems: radiators and floor radiant heating. Radiator systems use convection between the radiator and the indoor air, causing the room temperature to increase with height. The room temperature also varies with horizontal distance from the radiator, resulting in a large temperature gradient. Floor radiant heating systems radiate heat through the ground, primarily by radiation, causing the room temperature to decrease with height, resulting in an average surface temperature higher than the average room temperature.

[0005] Affected by room temperature gradients, the number of online room temperature monitoring devices deployed in a building's interior space, the location of measurement points, and the distance between the measurement points and heat sources, walls, and the ground all affect measurement accuracy. The room temperature data measured by the monitoring devices often differ significantly from the standard room temperature data. Furthermore, there has been a lack of feasible equipment and methods for calibration, resulting in a large amount of room temperature data measured by the numerous online room temperature monitoring devices already in use being non-authoritative and unusable as evidence of the standard room temperature, leading to significant waste.

[0006] In summary, online room temperature monitoring is of great significance to building energy conservation and emission reduction, and its application scope needs to be further expanded. How to reduce or eliminate the errors of the online room temperature monitoring system has become an urgent problem that needs to be solved. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to address the above shortcomings and provide an online indoor air temperature monitoring and calibration device and calibration method to solve the drift of the temperature sensor itself in the online room temperature monitoring equipment, drift during the installation process, and room temperature sensor sampling errors caused by the thermal effect of room temperature gradient changes. By calibrating the room temperature collector, the accuracy of its room temperature collection can be improved. Whether it is a radiator or a floor radiant heating system, the online room temperature monitoring device can be calibrated using the present invention.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] An indoor air temperature online monitoring and calibration device includes a host computer management system, a calibration device, and a room temperature online monitoring device; the calibration device includes a tripod head and a straight-arm head, the tripod head is integrated with a room temperature detection point positioning unit, a horizontal measurement unit, a drive unit, and a head control unit, and the straight-arm head is integrated with a standard room temperature measurement unit and a room temperature calibration unit.

[0010] Furthermore, the room temperature calibration unit includes a standard room temperature data storage module, a first short-range wireless communication module and a first long-range wireless communication module.

[0011] Furthermore, the room temperature online monitoring equipment includes a room temperature collector and a room temperature sensor. The room temperature collector includes a first temperature sensing module, a second short-range wireless communication module, a second long-range wireless communication module, a first data calculation module and a first data storage module. The room temperature sensor includes a second temperature sensing module, a third short-range wireless communication module and a second data storage module.

[0012] Furthermore, the host computer management system includes a data temporary storage module, a room temperature calibration calculation module and a calibrated room temperature storage application module, which has storage and room temperature sensor calibration functions, can accept the standard room temperature measured by the calibration equipment 10 and the room temperature data to be calibrated measured by the room temperature online monitoring equipment, correct the temperature sensor to be calibrated through the calibration algorithm, and store the calibration data for backup.

[0013] A calibration method for an indoor air temperature online monitoring and calibration device, wherein the calibration method determines the number, location, and distance of legal room temperature measurement points by a calibration device, measures the standard room temperature at the legal room temperature measurement points, stores the standard room temperature data, and remotely transmits the standard room temperature data to a host computer management system;

[0014] The room temperature online monitoring device can continuously and automatically measure the room temperature of the room, obtain the room temperature data to be calibrated, calculate and store the room temperature data measured by the room temperature online measurement unit, and collect the room temperature data in the same temperature measurement unit and transmit it remotely to the host computer management system;

[0015] The host computer management system processes the received standard room temperature and the room temperature to be calibrated, first obtains the compensation temperature of each temperature measuring unit in the building, and then generates calibrated room temperature data equal to or close to the standard room temperature through a calibration algorithm.

[0016] Furthermore, the calibration method includes the following steps:

[0017] Step a, fixedly installing the room temperature online monitoring equipment in each temperature measurement unit of a building space, using its installation location as a measurement point, continuously and automatically monitoring the room temperature, and measuring the room temperature data to be calibrated;

[0018] Step b, placing a room temperature calibration device in each temperature measuring unit of the building space in sequence, and completing the standard room temperature measurement work in a room equipped with a room temperature online monitoring device;

[0019] In step c, the host computer management system completes the calibration of the room temperature data of the living space, that is, through the room temperature calibration calculation module of the host computer management system, the compensation temperature is calculated in turn according to the standard room temperature and the room temperature data to be calibrated within the same statistical period of each temperature measuring unit, and the standard or near-standard room temperature data is obtained, and the data is stored in the calibration room temperature storage application module for use.

[0020] Furthermore, in step a, the number of rooms in which each temperature measurement unit needs to perform online room temperature monitoring is determined according to needs, and the number of the online room temperature monitoring devices installed in each room is implemented in accordance with national standards. When a temperature measurement unit only needs to install one online room temperature monitoring device, a room temperature collector should be installed; if multiple online room temperature monitoring devices need to be installed, a room temperature collector and multiple room temperature sensors should be configured as a group. The room temperature collector is connected to the host computer management system via NB-IOT and is connected to each room temperature sensor via 470MHZ to ensure the concentration and upload of the calibrated room temperature data of a temperature measurement unit.

[0021] Furthermore, in step c, within the same statistical period, the compensation temperature is calculated using formula 1 based on the average indoor temperature to be calibrated of each room in a temperature measurement unit collected by the room temperature online monitoring device and the standard indoor average temperature collected by the standard room temperature measurement unit of the calibration device:

[0022] ΔT=T ni -T n1i Formula 1;

[0023] Where: T ni —The average value of standard indoor temperature collected during the i-th statistical period, ℃;

[0024] Tn1i —The average indoor temperature to be calibrated collected during the i-th statistical period, ℃;

[0025] ΔT—compensation temperature, ℃.

[0026] Based on the compensation temperature, the calibrated indoor temperature can be obtained according to Formula 2:

[0027] T n =T n1 +ΔT Formula 2;

[0028] Where: T n —Indoor temperature after calibration, ℃;

[0029] T n1 —Room temperature to be calibrated, ℃;

[0030] ΔT—compensation temperature, ℃.

[0031] Furthermore, the calibration method includes the following steps:

[0032] Step d: The room temperature online monitoring device is fixedly installed in an indoor space of a building. The number of rooms where the device is installed is determined according to the room temperature monitoring needs. The number of devices installed in each room is configured in equal amounts according to the room area and the number of statutory monitoring points specified by national standards. When only one device is required to be installed in an indoor space, a room temperature collector should be installed for temperature measurement and data transmission; when multiple devices are required to be installed, a room temperature collector and multiple room temperature sensors should be installed.

[0033] Step e: installing the room temperature online monitoring device, i.e., a room temperature collector or a room temperature sensor, fixedly installed in the indoor space of the building, and continuously and automatically monitoring the room temperature at the installation location as a monitoring point, measuring the indoor temperature, and generating room temperature data to be calibrated;

[0034] Step f: Deploy a room temperature online monitoring equipment calibration system in sequence to the rooms in the building where the room temperature online monitoring equipment is installed, and complete the following tasks:

[0035] 1. Determine the location of the statutory monitoring point in the room through a statutory room temperature monitoring point positioning unit;

[0036] 2. Deploy a standard room temperature measurement unit to the legal monitoring point, measure the standard room temperature, and store it in the room temperature calibration unit;

[0037] 3. Set up the calibration equipment to communicate with the room temperature collector and room temperature sensor;

[0038] Step g, transmitting the standard room temperature data to the data calculation module of the room temperature online monitoring device through the room temperature calibration unit, that is, transmitting the standard room temperature data to the data calculation module of the room temperature collector or the data calculation module of the room temperature sensor;

[0039] In step h, the data calculation module of the room temperature online monitoring device calculates the compensation temperature of the room according to the standard room temperature and the room temperature to be calibrated in the same statistical period of the room, and obtains the standard or close to standard room temperature data after the room temperature online monitoring device is calibrated. The offline calibration of the room temperature online monitoring device is completed.

[0040] Furthermore, in step d, the selected room temperature online monitoring device must have 470 MHz short-range wireless communication and calibration algorithm calculation functions. When the calibration device is operated and connected to a room temperature online monitoring device corresponding to the statutory monitoring point, after receiving the standard room temperature data transmitted by the room temperature calibration unit, the room temperature online monitoring device completes the device calibration by performing room temperature calibration algorithm calculations through its own data calculation module.

[0041] In step d, when the area of a temperature measurement room is greater than 50 m2, the installation locations of multiple room temperature online monitoring devices, which are configured in the same number as the statutory monitoring points, should be as close as possible to the corresponding statutory monitoring points;

[0042] In step d, after all room temperature online monitoring devices of the temperature measuring units installed in a building space have completed offline calibration, a room temperature collector regularly collects the calibrated room temperature data of itself and each room temperature sensor, and uploads the average calibrated room temperature of the temperature measuring unit or the calibrated room temperature of each room of the temperature measuring unit to the calibrated room temperature storage application module of the host computer management system for use, depending on the setting;

[0043] In step e, when a temperature measurement room is larger than 50 m2 and has multiple statutory room temperature monitoring points, the room temperature monitoring equipment calibration system should be deployed to each statutory monitoring point in turn, and the room temperature online monitoring equipment corresponding to each statutory monitoring point should be calibrated respectively.

[0044] The present invention adopts the above technical solution, which has the following technical effects compared with the prior art:

[0045] The high-precision room temperature data collected by the room temperature calibrator at the measurement point specified by the national standard is used as calibration data to calibrate the room temperature collector installed on the wall. Through calibration, the room temperature collector whose installation position deviates from the statutory monitoring point can be calibrated online, thereby eliminating the error of the room temperature online monitoring device and improving the accuracy.

[0046] 1. Whether it is a room temperature online monitoring system for radiators, floor radiant heating, or other heating systems, by using the calibration of the present invention, standard or near-standard room temperature data can be obtained. It can expand the use scenarios and usage environments of the room temperature online monitoring equipment, thereby facilitating the promotion and popularization of the room temperature online monitoring system.

[0047] 2. It can simplify the procedure of calibrating a room temperature online monitoring device to reduce the cost of calibrating the room temperature online monitoring device.

[0048] 3. It can speed up the calibration process of a room temperature sensor to reduce the calibration time of the room temperature sensor.

[0049] 4. The system can conveniently and quickly determine the number, location, and distance of the legally required indoor room temperature measurement points in the building, and measure the standard room temperature for use in calibrating the online room temperature monitoring device. The system minimizes user interference during the process of measuring the standard room temperature at the legally required measurement points.

[0050] 5. When the calibration system equipment is measuring the standard room temperature at the statutory measuring point, it can automatically identify and process the situation where the calibration system equipment deviates from the statutory measuring point position and distance in a timely manner to ensure the accuracy of the standard room temperature measurement.

[0051] 6. When measuring the standard room temperature at the legal measuring points, the calibration system equipment can identify and handle sudden temperature rises and drops caused by human factors, so as to maintain the seriousness of the standard room temperature measurement.

[0052] 7. It can prevent interference from thermal radiation such as sunlight during the measurement of standard room temperature at the statutory measuring point, which may affect the measurement accuracy of standard room temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Example 1, as Figures 1 to 3 As shown, a device for online monitoring and calibration of indoor air temperature includes a host computer management system, a calibration device and an online room temperature monitoring device.

[0061] The calibration equipment includes a tripod head 9 and a straight arm head 10. The tripod head 9 is integrated with a room temperature detection point positioning unit, a horizontal measurement unit 4, a drive unit 5 and a head control unit 8. There are two horizontal measurement units 4, and the two horizontal measurement units 4 are respectively installed in a direction parallel to the straight arm head 10 and a direction perpendicular to the straight arm head 10. The room temperature detection point positioning unit includes a first laser ranging unit 1, a second laser ranging unit 2, and a third laser ranging unit 3. The straight arm head 10 is integrated with a standard room temperature measurement unit 62 and a room temperature calibration unit 65.

[0062] The calibration equipment also includes a tripod support frame 15, a tripod vertical telescopic rod 14 is installed on the top of the tripod support frame 15, a tripod head 9 is installed on the top of the tripod vertical telescopic rod 14, a straight arm head 10 is fixed on the tripod head 9, a rotary stepping motor 11 is installed on the tripod vertical telescopic rod 14, the straight arm head 10 includes a straight arm head telescopic rod 12 and a balancing telescopic rod 13, the balancing telescopic rod 13 is installed above the straight arm head telescopic rod 12, the straight arm head telescopic rod 12 and the balancing telescopic rod 13 are synchronously telescoped in opposite directions to keep the equipment balanced.

[0063] The rotary stepper motor 11 is installed perpendicular to the tripod head 9, and can drive the tripod head 9 and the straight arm head 10 to rotate and change their angles. At the same time, it can drive the straight arm head telescopic rod 12 and the balance telescopic rod 13 to synchronously extend and retract to change the length of the straight arm head 10. The head control unit 8 controls the action of the rotary stepper motor 11.

[0064] The calibration device is placed at a point O' in the indoor space of a building, and the telescopic platform 10 is adjusted to a given height of 1m-1.5m. The distances from O' to the three corners of the room are measured by the first laser ranging unit 1, the second laser ranging unit 2, and the third laser ranging unit 3. The angles in the three directions are measured by the rotation of the stepping motor 11. The distance d and the angle β from O' to the legal measuring point O of the room temperature in the indoor space are calculated by trigonometric calculation.

[0065] In order to achieve the statutory room temperature measurement point position, distance measurement and position provision, before positioning the statutory room temperature measurement point, it is necessary to use the horizontal measurement unit 4 to perform horizontal leveling, height measurement and adjustment on the straight arm pan-tilt platform 10. After positioning the statutory measurement point O, it is necessary to rotate the straight arm pan-tilt platform 10 by β degrees to point in the direction of point O, adjust the length of the straight arm pan-tilt platform telescopic rod 12, deploy the standard room temperature measurement unit 62 located on the straight arm pan-tilt platform to the measured statutory measurement point O, turn on the power to measure the standard room temperature, and in order to maintain the balance of the straight arm pan-tilt platform 10, a balancing telescopic rod 13 is added above the telescopic rod 12 of the straight arm pan-tilt platform, which is synchronously extended and retracted with the telescopic rod 12 of the straight arm pan-tilt platform.

[0066] The horizontal adjustment of the straight arm platform 10 is completed by manually operating the bidirectional level measuring unit on the tripod platform 9 and the leveling screws installed on the vertical telescopic rod 14 of the tripod.

[0067] The height measurement and adjustment of the straight arm platform are completed by the third laser ranging unit 3 (accuracy 1mm) and the vertical telescopic rod 14 installed on the vertical tripod platform 9 through electronically controlled automatic adjustment.

[0068] The measurement and positioning of the statutory room temperature measuring point is carried out by a laser ranging unit 1 horizontally mounted on the tripod platform and a vertically mounted rotary stepping motor 11 (resolution 0.05°), which is automatically adjusted by electronic control and manually confirmed at the three angles by a remote control. After measuring the distances a, b, c and angles of the three angles, the rotation angle β and distance d from the standard room temperature measuring unit 62 to the statutory room temperature measuring point O of the room are calculated. The platform control unit 8 converts the calculated angle into the number of steps of motor rotation and turns the end of the straight arm platform 10 on which the standard room temperature measuring unit 62 is mounted toward the direction of the statutory room temperature measuring point O.

[0069] The laser ranging unit 2 and the telescopic rod 12 horizontally mounted on the telescopic arm platform 10 adjust the distance d between the standard room temperature measurement unit 62 mounted at one end of the telescopic arm platform and the statutory room temperature measurement point O, and deploy the standard room temperature measurement unit 62 to the statutory room temperature measurement point position to perform statutory room temperature measurement.

[0070] Optionally, the control measurement, measurement data calculation, remote control communication, data display and other tasks of the laser rangefinder and the electric telescopic rod are all completed by the calibration device control unit installed on the tripod head.

[0071] By operating the telescopic rod 12 of the calibration device, the standard room temperature measurement unit 62 can be deployed at a legal measuring point above furniture with a height of less than 1.5m, avoiding or reducing interference with the user's normal work and life order during the standard room temperature measurement process.

[0072] In addition, if Figure 4 As shown, preferably, the standard room temperature measurement unit 62 of the calibration device integrates a platinum resistance digital temperature sensor and a DS18B20 digital temperature sensor, with a measurement accuracy of ±0.15°C, providing reliable high-precision standard room temperature data for calibrating the room temperature online monitoring device.

[0073] Preferably, the standard room temperature measurement unit 62 can identify the horizontal and vertical displacements in real time through the built-in G-sensor and the data changes of the first laser ranging unit 1, the second laser ranging unit 2, and the third laser ranging unit 3, and report them to the host computer management system for processing to ensure the accuracy of the standard room temperature measurement results.

[0074] Those skilled in the art should understand that the standard room temperature measurement unit 62 can, but is not limited to, perform displacement identification and judgment through a built-in G-sensor and a laser locator, and its displacement judgment method can also be implemented as other methods as needed.

[0075] Furthermore, the heat shield housing of the standard room temperature measurement unit 62 utilizes a louvered, radiation-proof ventilation hood structure constructed from high-quality UV-resistant materials to minimize measurement errors caused by intense light. Specifically, a DS18B20 digital temperature sensor is installed on the top of the heat shield housing to identify any obstruction of the ventilation hood and human intervention in measurement results, reporting this information to the host computer management system for processing and ensuring the integrity of the measurement data.

[0076] The room temperature calibration unit 65 includes a standard room temperature data storage module, a first short-range wireless communication module, and a first long-range wireless communication module.

[0077] The communication method between the calibration device and the host computer is NB-IOT, and the communication method with the room temperature online monitoring device is 470MHZ. Those skilled in the art should understand that the above-mentioned communicative connection can be a wired connection connected by a data cable, an electric wire, etc., or it can be a wireless connection connected by 433MHz, LORA, WIFI, Bluetooth, or infrared, etc. In other words, the communicative connection is not the focus of the present invention, and the present invention does not impose further restrictions on the specific communication connection method.

[0078] The room temperature online monitoring equipment includes a room temperature collector and a room temperature sensor. The room temperature collector includes a first temperature sensing module, a second short-range wireless communication module, a second long-range wireless communication module, a first data calculation module and a first data storage module. The room temperature sensor includes a second temperature sensing module, a third short-range wireless communication module and a second data storage module.

[0079] The room temperature sensor and the room temperature collector can be connected via 470MHZ short-range wireless communication, wherein the room temperature collector 31 is connected to the host computer management system 50 via NB-IOT communication. Figure 3 As shown, the calibration device is connected to the host computer management system 50 via NB-IOT communication.

[0080] The host computer management system includes a data temporary storage module, a room temperature calibration calculation module and a calibrated room temperature storage application module, which has storage and room temperature sensor calibration functions. It can accept the standard room temperature measured by the calibration equipment 10 and the room temperature data to be calibrated measured by the room temperature online monitoring equipment, correct the temperature sensor to be calibrated through the calibration algorithm, and store the calibration data for backup.

[0081] like Figure 5 and Figure 6 As shown, a calibration method for an indoor air temperature online monitoring and calibration device includes the following steps:

[0082] Step a, fixedly installing the room temperature online monitoring equipment in each temperature measurement unit of a building space, using its installation location as a measurement point, continuously and automatically monitoring the room temperature, and measuring the room temperature data to be calibrated;

[0083] Step b: placing a room temperature calibration device in each temperature measuring unit of the building space in turn, and completing the standard room temperature measurement work in a room equipped with a room temperature online monitoring device.

[0084] In step c, the host computer management system completes the calibration of the room temperature data of the living space, that is, through the room temperature calibration calculation module of the host computer management system, the compensation temperature is calculated in turn according to the standard room temperature and the room temperature data to be calibrated within the same statistical period of each temperature measuring unit, and the standard or near-standard room temperature data is obtained, and the data is stored in the calibration room temperature storage application module for use.

[0085] In step a, the number of rooms requiring online room temperature monitoring in each temperature measurement unit is determined as needed, and the number of online room temperature monitoring devices installed in each room is implemented in accordance with national standards. When a temperature measurement unit only needs to install one online room temperature monitoring device, a room temperature collector should be installed; if multiple online room temperature monitoring devices need to be installed, one room temperature collector and multiple room temperature sensors should be configured as a group. The room temperature collector is connected to the host computer management system via NB-IOT and is connected to each room temperature sensor via 470MHZ to ensure the centralization and upload of the room temperature data to be calibrated of a temperature measurement unit.

[0086] The installation location of the room temperature online monitoring equipment should be as close as possible to the corresponding statutory measuring point location according to on-site construction conditions.

[0087] In step a, the room temperature sensor must be immovably fixed in the living space.

[0088] The step b includes the following steps (taking a room smaller than 50 m2 as an example):

[0089] 1. Determine the position of a statutory measuring point in the room by using the statutory room temperature monitoring point positioning unit;

[0090] 2. Sequentially deploy the standard room temperature measurement units to the statutory monitoring points;

[0091] 3. Operate the standard room temperature measurement unit to collect room temperature data, collecting data every 30 seconds. When the room temperature reading collected each time is stable, the system determines that the data is valid and stores the room temperature data in the standard room temperature data storage module of the room temperature calibration unit.

[0092] 4. Set the room temperature calibration unit to communicate with the host computer management system and upload the standard room temperature data to the data temporary storage module of the host computer management system.

[0093] In step c, within the same statistical period, the compensation temperature is calculated using formula 1 based on the average indoor temperature to be calibrated of each room in a temperature measurement unit collected by the room temperature online monitoring device and the standard indoor average temperature collected by the standard room temperature measurement unit of the calibration device:

[0094] ΔT=Tni -T n1i Formula 1;

[0095] Where: T ni —The average value of standard indoor temperature collected during the i-th statistical period, ℃;

[0096] T n1i —The average indoor temperature to be calibrated collected during the i-th statistical period, ℃;

[0097] ΔT—compensation temperature, ℃.

[0098] Based on the compensation temperature, the calibrated indoor temperature can be obtained according to Formula 2:

[0099] T n =T n1 +ΔT Formula 2;

[0100] Where: T n —Indoor temperature after calibration, ℃;

[0101] T n1 —Room temperature to be calibrated, ℃;

[0102] ΔT—compensation temperature, ℃.

[0103] Example 2: Compared with Example 1, this example is modified as follows:

[0104] like Figures 7 to 9 As shown, a calibration method for an indoor air temperature online monitoring and calibration device includes the following steps:

[0105] Step d: The room temperature online monitoring device is fixedly installed in an indoor space of a building. The number of rooms where the device is installed is determined according to the room temperature monitoring needs. The number of devices installed in each room is configured in equal amounts according to the room area and the number of statutory monitoring points specified by national standards. When only one device is required to be installed in an indoor space, a room temperature collector should be installed for temperature measurement and data transmission; when multiple devices are required to be installed, a room temperature collector and multiple room temperature sensors should be installed.

[0106] Step e: installing the room temperature online monitoring device, i.e., a room temperature collector or a room temperature sensor, fixedly installed in the indoor space of the building, and continuously and automatically monitoring the room temperature at the installation location as a monitoring point, measuring the indoor temperature, and generating room temperature data to be calibrated;

[0107] Step f: Deploy a room temperature online monitoring equipment calibration system in sequence to the rooms in the building where the room temperature online monitoring equipment is installed, and complete the following tasks:

[0108] 1. Determine the location of the statutory monitoring point in the room through a statutory room temperature monitoring point positioning unit;

[0109] 2. Deploy a standard room temperature measurement unit to the legal monitoring point, measure the standard room temperature, and store it in the room temperature calibration unit;

[0110] 3. Set up the calibration equipment to communicate with the room temperature collector and room temperature sensor.

[0111] Step g: transmitting the standard room temperature data to the data calculation module of the room temperature online monitoring device through the room temperature calibration unit, that is, transmitting the standard room temperature data to the data calculation module of the room temperature collector or the data calculation module of the room temperature sensor.

[0112] In step h, the data calculation module of the room temperature online monitoring device calculates the compensation temperature of the room according to the standard room temperature and the room temperature to be calibrated in the same statistical period of the room, and obtains the standard or close to standard room temperature data after the room temperature online monitoring device is calibrated. The offline calibration of the room temperature online monitoring device is completed.

[0113] In step d, the selected room temperature online monitoring equipment must have 470Mhz short-range wireless communication and calibration algorithm calculation functions. After the calibration equipment is operated and connected to the room temperature online monitoring equipment corresponding to the statutory monitoring point, after receiving the standard room temperature data transmitted by the room temperature calibration unit, the room temperature online monitoring equipment completes the equipment calibration through the room temperature calibration algorithm calculated by its own data calculation module.

[0114] The offline labeling method for the room temperature collector and the room temperature sensor of the room temperature online monitoring equipment is the same.

[0115] In step d, when the area of a temperature measurement room is greater than 50 m2, the installation positions of multiple room temperature online monitoring devices, which are configured in the same number as the statutory monitoring points, should be as close as possible to the corresponding statutory monitoring point positions.

[0116] In step d, after all room temperature online monitoring devices of the temperature measuring unit installed in a building space have completed offline calibration, a room temperature collector regularly collects the calibrated room temperature data of itself and each room temperature sensor, and uploads the average calibrated room temperature of the temperature measuring unit or the calibrated room temperature of each room of the temperature measuring unit to the calibrated room temperature storage application module of the host computer management system for use, depending on the settings.

[0117] In step e, when a temperature measurement room is larger than 50 m2 and has multiple statutory room temperature monitoring points, the room temperature monitoring equipment calibration system should be deployed to each statutory monitoring point in turn, and the room temperature online monitoring equipment corresponding to each statutory monitoring point should be calibrated respectively.

[0118] In step h, within the same statistical period, the compensation temperature is calculated using Formula 1 based on the average indoor temperature to be calibrated of each room in a temperature measurement unit collected by the room temperature online monitoring device and the standard indoor average temperature collected by the standard room temperature measurement unit of the calibration device:

[0119] ΔT=T ni -T n1i Formula 1;

[0120] Where: T ni —The average value of standard indoor temperature collected during the i-th statistical period, ℃;

[0121] T n1i —The average indoor temperature to be calibrated collected during the i-th statistical period, ℃;

[0122] ΔT—compensation temperature, ℃.
