Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wind pressure collecting equipment, and particularly relates to a wireless wind pressure monitoring device combined with an absolute pressure sensing module. BACKGROUND

[0002] In recent years, wind disasters occur frequently, and major engineering accidents are common. Wind load is one of the control loads of large-span complex structures, and the research methods of roof wind load are mostly limited to numerical simulation and laboratory wind tunnel, and field measurement is an effective means to study wind load. Limited by the existing wind pressure measurement equipment, the installation is difficult, the working conditions are complex, and the durability is poor, the wind load measurement work of large-span structure surface is slow, and as the core equipment of the wind pressure monitoring system, a wind pressure monitoring device suitable for large-area roof is essential for roof wind pressure measurement.

[0003] At present, in the application of structure wind pressure measurement, in order to obtain the air pressure of the building surface, the outdoor wireless wind pressure monitoring device often uses differential pressure or gauge pressure sensor, and the reference pressure end of all sensors needs to be connected through pipeline, and connected to the indoor space less affected by wind through an air pipe. The large-span space structure roof has complex shape and large area, and connecting a large number of wind pressure measuring points requires laying thousands of meters of pipeline, which restricts the application of wind pressure measurement technology on larger area roof. In addition, due to the influence of gas supply pressure, temperature, humidity and air pipe size, a certain amount of water vapor will accumulate in the sensor pipeline during long-term use, when the external environment temperature is lower than the saturation temperature of the air, the water vapor in the air near the surface of the pipeline will condense into water droplets, and because the pipeline system is relatively closed, the water cannot be effectively discharged and accumulates in the pipeline. At the same time, the backwardness of the central control, communication and power module of the traditional wind pressure monitoring device also cannot meet the demand of wind pressure monitoring of large-span space structure. Therefore, a new type of wind pressure monitoring device without external reference pressure, without pipeline connection and with new type of central control, communication and power module is urgently needed. SUMMARY

[0004] In view of the above-mentioned deficiencies of the existing wind pressure monitoring device, the application innovates the sensor collecting module based on absolute pressure sensing technology, perfects the power module by using solar charging system, and improves the rain and snow protection ability of the device by combining with waterproof and breathable mechanical device, so as to provide a wireless wind pressure monitoring device combined with absolute pressure sensing module, solve the problems of laying pipeline on large-area roof of traditional wind pressure monitoring device, realize pipeline-free collection of high-frequency wind pressure data, and meet the wind load measurement of large-area coverage, high sampling rate and synchronous collection of multiple measuring points.

[0005] The technical scheme adopted by the application is:

[0006] A wireless wind pressure monitoring device integrating an absolute pressure sensing module is characterized by comprising a sensor acquisition module, a central control module, a wireless communication module, and a power supply module. The power supply module includes an internal power supply module and a solar panel, with the solar panel mounted on top of a waterproof and breathable mechanical device. The sensor acquisition module, central control module, wireless communication module, and internal power supply module are respectively installed inside the waterproof and breathable mechanical device, which is placed at a wind pressure measuring point on the roof. The specific composition of each module is as follows:

[0007] The sensor acquisition module includes an absolute pressure sensor and an A / D converter. The absolute pressure sensor is installed at the water-blocking and air-breathing inlet on the waterproof and breathable mechanical device. The absolute pressure sensor is connected to the central control module via the A / D converter. The absolute pressure sensor receives data acquisition commands transmitted from the central control module and acquires high-frequency wind pressure data filtered by the waterproof and breathable mechanical device. The A / D converter converts the high-frequency wind pressure data acquired by the absolute pressure sensor into analog signals and stores the data in the flash memory of the central control module via the SPI protocol. Unlike differential pressure sensors that directly measure the relative pressure between indoors and outdoors, the absolute pressure sensor avoids the installation of pipes on the roof. Therefore, an absolute pressure sensor needs to be installed in a location inside the roof that is less affected by wind as a reference pressure. The difference between the two can be considered as the wind pressure caused by air movement. The wind-induced pressure on the building surface is defined as the total dynamic pressure recorded by the wind pressure sensor on the roof minus the environmental dynamic pressure measured by the indoor sensor, expressed as:

[0008] (1-1)

[0009] in for Time of the first Instantaneous wind pressure at the measuring point It is the roof. The pressure difference measured by the wind pressure sensor at the measuring point before and after the arrival of strong winds. It is the first indoor reference point. The pressure difference at the measuring point is measured by the wind pressure sensor before and after a strong wind. The pressure difference at the same measuring point is determined by two measurements: the atmospheric pressure in calm conditions and the atmospheric pressure during a strong wind.

[0010] (1-2)

[0011] in for At the moment of the roof The pressure difference measured by the wind pressure sensor at the measuring point before and after the arrival of strong winds. Measured during strong winds Time of the first The absolute atmospheric pressure at the measuring point is the average value of a segment of initial atmospheric pressure value measured by the sensor in the windless state, as the initial atmospheric pressure value of the measuring point in this measurement; when strong wind comes, the atmospheric pressure of indoor and outdoor will change, and the differential pressure change value of the two measuring points of indoor and outdoor can be considered as the wind pressure caused by the wind field; by substituting formula (1-2) into formula (1-1), the wind pressure of the measuring point obtained by the absolute pressure sensor can be obtained:

[0012] (1-3)

[0013] The central control module is responsible for managing each module and issuing task execution commands to each module; the central control module drives the sensor collection module to collect data according to the instructions of the superior or terminal Base, and temporarily stores the collected data using an intelligent storage algorithm, while controlling the wireless communication module to return data and instructions;

[0014] The wireless communication module is responsible for communicating with superior and subordinate devices, receiving the measuring point wind pressure data packet generated by the central control module and passing the superior instructions to the central control module, and uploading the measuring point wind pressure data packet to the superior, and the background system analyzes the data and issues further instructions;

[0015] The power module provides real-time power supply to each module to realize real-time collection of wind pressure data; the internal power module includes a lithium battery and a charge and discharge protection submodule, the solar panel is connected to the internal charge and discharge protection submodule through wires, the solar panel adjusts the power supply through the charge and discharge protection submodule to judge the remaining capacity of the power supply, realizing sustainable power supply of the wireless wind pressure monitoring device; the charge and discharge protection submodule is used to judge the remaining capacity of the power supply to prevent damage to the power supply caused by overcharging; the lithium battery supplies power to the central control module, the wireless communication module and the sensor collection module.

[0016] Further, the central control module is divided into three operation modes according to the energy consumption: working mode, standby mode and hibernation mode. The central control module uses an intelligent storage algorithm to realize fast and efficient storage and reading of dynamically collected data according to the superior instructions; controls the sensor collection module to perform data collection tasks; controls the wireless communication module to return data and instructions; and is powered by the lithium battery in the power module.

[0017] The wireless communication module has functions such as networking, point transmission, encrypted communication, etc., and is responsible for communicating with superior and subordinate devices, and uses spread spectrum communication technology to improve the anti-interference ability of signal transmission, which has the advantages of longer communication distance, lower power consumption and higher air transmission rate compared with the wireless communication chip used in the previous wind pressure monitoring device.

[0018] The sensor acquisition module is mainly responsible for switching of the sensor and data acquisition; after receiving the electric signal of the central controller, the sensor starts to measure data, and stores the data in the flash memory of the central control module through the SPI protocol, and after completing the acquisition task, the sensor acquisition module cuts off the power supply of the sensor to reduce the energy consumption of the whole device.

[0019] Compared with the prior art, the beneficial effects of the present application are embodied in that:

[0020] 1. Compared with the traditional wind pressure monitoring sensor, the new wireless wind pressure monitoring device combined with the absolute pressure sensing module adopts a new type of absolute pressure sensor instead of a differential pressure sensor or a gauge pressure sensor, solves the problems of difficult measurement point layout, pipe water vapor condensation and high cost caused by laying pipes on the large area roof of the wind pressure sensor, realizes pipe-free collection of high-frequency wind pressure data, improves the flexibility of measurement point layout, greatly reduces the cost of measurement point layout, and ensures the accuracy of wind pressure data collection;

[0031] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0034] like Figure 1 As shown, sensor acquisition module 1 is connected to waterproof and breathable mechanical device 8 via a horizontal rubber hose, and is connected to central control module 2 and internal power module 4 via wires. Central control module 2 is connected to sensor acquisition module 1, wireless communication module 3, and internal power module 4 via wires.

Aluminum battery, solar panel, and charge / discharge protection submodule together constitute power module, and are connected to sensor acquisition module 1, central control module 2, and wireless communication module 3 via wires.

[0035] like Figure 2As shown, the present invention discloses a wireless wind pressure monitoring device incorporating an absolute pressure sensing module, comprising a sensor acquisition module 1, a central control module 2, a wireless communication module 3, and a power supply module. The power supply module includes an internal power supply module 4 and a solar panel 6, with the solar panel 6 mounted on top of a waterproof and breathable mechanical device 8. The sensor acquisition module 1, central control module 2, wireless communication module 3, and internal power supply module 4 are respectively installed inside the waterproof and breathable mechanical device 8, which is placed at a wind pressure measuring point on the roof. The specific configuration of each module is as follows:

[0036] The sensor acquisition module 1 includes an absolute pressure sensor and an A / D converter. The absolute pressure sensor is installed at the water-blocking and air-breathing inlet 7 on the waterproof and breathable mechanical device 8. The absolute pressure sensor is connected to the central control module 2 via the A / D converter. The absolute pressure sensor receives data acquisition commands transmitted from the central control module 2 and acquires high-frequency wind pressure data filtered by the waterproof and breathable mechanical device 8. The A / D converter converts the high-frequency wind pressure data acquired by the absolute pressure sensor into analog signals to digital signals and stores the data in the flash memory of the central control module 2 via the SPI protocol. Unlike differential pressure sensors that directly measure the relative pressure between indoors and outdoors, absolute pressure sensors avoid installing pipes on the roof. Therefore, an absolute pressure sensor needs to be installed in a location inside the roof that is less affected by wind as a reference pressure. The difference between the two can be considered as the wind pressure caused by air movement. The wind-induced pressure on the building surface is defined as the total dynamic pressure recorded by the wind pressure sensor on the roof minus the environmental dynamic pressure measured by the indoor sensor, expressed as:

[0037] (1-1)

[0038] in for Time of the first Instantaneous wind pressure at the measuring point It is the roof. The pressure difference measured by the wind pressure sensor at the measuring point before and after the arrival of strong winds. It is the first indoor reference point. The pressure difference at the measuring point is measured by the wind pressure sensor before and after a strong wind. The pressure difference at the same measuring point is determined by two measurements: the atmospheric pressure in calm conditions and the atmospheric pressure during a strong wind.

[0039] (1-2)

[0040] in for At the moment of the roof The pressure difference measured by the wind pressure sensor at the measuring point before and after the arrival of strong winds. Measured during strong winds Time of the first Absolute atmospheric pressure of the measuring point, is the average value of a segment of initial atmospheric pressure values measured by the sensor in the windless state, as the initial atmospheric pressure value of the measuring point in this measurement; when strong wind comes, the atmospheric pressure of indoor and outdoor will change, and the differential pressure change value of the two measuring points can be considered as the wind pressure caused by the wind field; by substituting formula (1-2) into formula (1-1), the wind pressure of the measuring point obtained by the absolute pressure sensor can be obtained:

[0041] (1-3)

[0042] The central control module 2 is responsible for managing each module and issuing task execution commands to each module; the central control module 2 drives the sensor acquisition module 1 to collect data according to the instructions of the superior or terminal Base, and temporarily stores the collected data by using an intelligent storage algorithm, and controls the wireless communication module 3 to return data and instructions;

[0043] The wireless communication module 3 is responsible for communication with the superior and subordinate devices, receives the measuring point wind pressure data packet generated by the central control module 2 and transmits the superior instruction to the central control module 2, and uploads the measuring point wind pressure data packet to the superior, and the background system analyzes the data and issues further instructions;

[0044] The power module provides real-time power supply to each module to realize real-time collection of wind pressure data; the internal power module 4 includes a lithium battery and a charge and discharge protection sub-module arranged in the waterproof and breathable mechanical device 8, the solar panel 6 is connected with the internal charge and discharge protection sub-module through wires, the solar panel adjusts the power supply through the charge and discharge protection sub-module to judge the remaining capacity of the power supply, and realizes sustainable power supply of the wireless wind pressure monitoring device multi-module; the charge and discharge protection sub-module is used to judge the remaining capacity of the power supply to prevent damage to the power supply caused by overcharging; the lithium battery supplies power to the central control module 2, the wireless communication module 3 and the sensor acquisition module 1.

[0045] The device of the application is placed in a roof wind pressure measuring point under the protection of a waterproof and breathable mechanical device 8. After external air passes through the water-blocking and air-inlet 7 and is filtered, it enters the sensor collection module 1 through the horizontal rubber hose. After the central control module 2 receives the upper data collection instruction transmitted by the wireless communication module 3, it issues a work instruction to the sensor collection module 1. The sensor collection module 1 stores the collected high-frequency wind pressure data to the central control module 2. After the central control module 2 preliminarily processes the data, it is packaged and transmitted to the wireless communication module 3, which is sent to the superior unit through the gain antenna 5. During this period, the internal power module 4 and the solar panel 6 jointly constitute a power module that continuously supplies power to the sensor collection module 1, the central control module 2 and the wireless communication module 3. When the charge and discharge protection sub-module in the internal power module 4 detects that the lithium battery is insufficient, the solar panel 6 converts solar energy into electrical energy to charge the lithium battery. When the charge and discharge protection sub-module detects that the lithium battery is fully charged, the charge and discharge protection sub-module will cut off the solar charging path to prevent overcharging damage to the lithium battery.

[0046] As shown in Figure 3 , it is the absolute pressure sensor structure cross-sectional view of the application. Unlike traditional differential pressure sensors and gauge pressure sensors, the reference pressure end of the absolute pressure sensor does not need to be connected to the pipeline to obtain the external reference pressure, and its reference pressure is fixed as a vacuum state. The application uses an absolute pressure sensor, thereby effectively solving the problems of water vapor condensation of the external pipeline, complex pipeline laying, and environmental test errors.

[0047] As shown in Figure 4 , it is the sensor collection module running flow chart of the application, specifically as follows:

[0048] After the sensor collection module receives the central controller instruction, the sensor collection module is connected to the power module and performs the collection task. After the absolute pressure sensor directly collects the physical quantity, the pre-processing circuit converts the collected information into an electrical signal, and then the A / D converter converts the analog quantity into a digital quantity, and finally the data is stored in the central control module flash memory. If the collection task has not been completed at this time, the sensor module will continue to perform the collection task. If the task has been completed at this time, the sensor module will disconnect the power supply to reduce energy consumption.

[0049] As shown in Figure 5 , it is the central control module running flow chart of the application, specifically as follows:

[0050] After the device starts running, the central control module is in a low-power sleep mode; after receiving a superior wake-up instruction, the central control module is converted into a standby mode, ready to receive further instructions and execute tasks; if the central control module does not receive a superior specific task instruction within ten minutes, it is reconverted into a low-power sleep mode; if a specific instruction is accepted, it is converted into a working mode; when executing the task instruction, the central control module issues a data collection instruction to the sensor collection module; after the sensor collection module collects sufficient data, the data is transmitted to the central control module for temporary storage; the central control module packages the data and transmits it to the wireless communication module, and issues a return instruction to the wireless communication module, which is responsible for returning the data packet; thereafter, the central control module will be converted into a standby mode to wait for superior instructions, and if no superior instructions are received within ten minutes, it is converted into a low-power sleep mode.
