Description

Technical Field

[0001] This invention relates to the field of formwork monitoring technology in building construction, and in particular to a high-support formwork displacement monitoring system and method. Background Technology

[0002] With the acceleration of urbanization and the rapid development of construction technology, high formwork systems have been used more and more widely as a formwork support system. Due to the diversity, complexity and high risk of high formwork systems, collapse accidents of high formwork systems have occurred frequently in recent years, thus putting forward higher requirements for the safety management of high formwork systems.

[0003] In the past, traditional methods for measuring the horizontal displacement of high formwork mainly involved using total stations and reflectors or using drawstring displacement sensors to measure changes. The measurement methods of total stations and reflectors have drawbacks such as high requirements for line of sight and the inability to measure the internal condition of the support when the measuring point is set on the outside of the support, making it difficult to prevent accidents. On the other hand, drawstring displacement sensors require one end of the drawstring to be fixed to the member to be monitored and the other end to be fixed to a stable working reference point. During the drawstring monitoring process, it is easily affected by external environmental interference such as wind, rain, and accidental collisions with scaffolding during construction, resulting in inaccurate data. Therefore, it is not suitable for large-scale promotion and application.

[0004] The existing Chinese patent publication number CN110243294A, entitled "Real-time Monitoring System for Displacement of High Formwork Support Pole Based on CCD Image Sensor Application," discloses a real-time monitoring system for displacement of high formwork support poles based on a CCD image sensor. This system utilizes a laser emitter to emit a laser beam, which illuminates a CCD panel to form a detection image. An analysis module analyzes the movement of the detection image and evaluates the displacement value of the high formwork support pole based on the displacement value of the detection image. However, it has the following drawbacks in practical use: 1. The laser beam directly illuminates the CCD device, making the CCD device prone to aging and failure, resulting in a short lifespan; 2. The laser emitting device and the CCD device are respectively arranged at the emission point and the monitoring point. Due to the small light-receiving area of ​​the CCD device and the dispersed and distant locations of the on-site monitoring points, on-site installation and debugging are extremely difficult. Summary of the Invention

[0005] The present invention aims to solve the above problems, thereby providing a high-support displacement monitoring system and monitoring method that can extend the life of CCD devices and is easy to debug.

[0006] The invention solves the aforementioned problem by employing the following technical solution:

[0007] A high-support formwork displacement monitoring system includes several data acquisition modules and a central communication module connected to the data acquisition modules. Each data acquisition module includes an acquisition controller and a monitoring component connected to the acquisition controller. The monitoring component includes a laser emitter and a CCD sensor, and also includes a support frame. The monitoring component is detachably connected to the support frame. A positioning plate is installed at the monitored point. The laser emitter emits a laser beam towards the monitored point, and the emitted laser beam is projected onto the positioning plate to form a light spot. The light spot is projected onto the CCD sensor. The system also includes a smart construction site management platform. The CCD sensor transmits the light spot position signal to the acquisition controller, which then transmits the light spot position signal to the smart construction site management platform via the central communication module. The smart construction site management platform includes a main server connected to the central communication module, and the main server is connected to a database, a large display screen, and an alarm module.

[0008] As a preferred embodiment, a further technical solution of the present invention is:

[0009] It also includes an optical zoom filter, which is located between the positioning plate and the CCD sensor. It is used to filter out other spectra such as natural light and only allow laser light to pass through. After the light is filtered and zoomed by the optical zoom filter, the light spot is focused and projected onto the CCD sensor.

[0010] The support frame includes a monitoring component support frame for mounting the monitoring components, a filter support frame for mounting the optical zoom filter, and a positioning plate support frame for mounting the positioning plate. The monitoring component support frame is equipped with a support plate, which has an isosceles triangular recessed mounting groove. The laser emitter and CCD sensor are respectively mounted on the two sides of the mounting groove. The laser emitter and CCD sensor are arranged on both sides of the same mounting groove, which solves the problem of the scattered and far-distance location of the on-site monitoring points and the difficulty of installing and debugging the laser emitter and CCD sensor.

[0011] Each monitoring component support frame is equipped with two support plates arranged in a T-shape; the laser emitter includes a first emitter and a second emitter, and the CCD sensor includes a first sensor and a second sensor; the first emitter and the first sensor are installed in the mounting slot of one of the support plates, and the second emitter and the second sensor are installed in the mounting slot of the other support plate; it can simultaneously monitor displacement in the horizontal and vertical directions.

[0012] The acquisition controller includes an acquisition processor, which is connected to a signal conditioning circuit, a transmission control circuit, a register output circuit, a DA conversion circuit, a shaping and filtering circuit, and a substation wireless network communication unit. The signal conditioning circuit is connected to the CCD sensor, the transmission control circuit is connected to the laser transmitter, and the substation wireless network communication unit is connected to the main station communication module.

[0013] The branch station wireless network communication unit and the main station communication module adopt the LORA wireless communication module. The LORA wireless communication module adopts a cluster working mode, which enables the main station communication module to receive communication signals from multiple branch station wireless network communication units at the same time, making data processing more efficient and facilitating integrated management of various monitoring points.

[0014] The present invention also provides a method for monitoring the displacement of high formwork, which uses a high formwork displacement monitoring device and includes the following steps:

[0015] S1, Install support frame: Set up a support frame for the positioning plate at the monitored point of the high formwork scaffold, and install the positioning plate; set up a support frame for the monitoring component for monitoring the relative position change within the high formwork scaffold at the monitoring point of the high formwork scaffold, and install the monitoring component; enable the laser emitter to emit laser light that can be projected onto the positioning plate to form a light spot, and the light spot can be projected onto the CCD sensor;

[0016] S2, Install optical zoom filter: Set up a filter support frame between the corresponding positioning plate and the CCD sensor, install the optical zoom filter on the filter support frame, and position the optical zoom filter on the projection path of the light spot and the CCD sensor. Adjust the angle of the optical zoom filter to make the light spot projection clear.

[0017] S3, Data Acquisition: The data acquisition module controls the laser emitter to emit a laser beam onto the positioning plate to form a light spot. After the light spot is filtered and focused by the optical zoom filter, it is projected onto the CCD sensor. The CCD sensor transmits the light spot position signal to the data acquisition module. The acquisition module transmits the light spot position signal to the main server of the smart construction site management platform through the main station communication module.

[0018] S4: Data Processing: The main server of the smart construction site management platform stores the light spot position signals in the database according to the time dimension for long-term storage and retrieval. The main server calculates the displacement by performing vector difference calculation between each measured light spot position signal and the initial light spot position signal. The main server has preset displacement warning values ​​and displacement alarm values. When the displacement reaches the displacement warning value or displacement alarm value, the main server controls the alarm module to issue a warning and alarm. At the same time, the management personnel obtain real-time data, historical data, graphs and reports generated from historical data, and alarm information through the main server. The real-time data, historical data, graphs and reports generated from historical data, and alarm information are transmitted to the display screen for display.

[0019] Furthermore, step S1 also includes setting up a monitoring component support frame on the foundation for monitoring the overall positional changes of the high formwork scaffold, and installing another set of monitoring components.

[0020] It also includes a mobile terminal, which can connect to the main server via WIFI or hotspot to the main station communication module to obtain real-time status, alarm information, and graphs and reports generated from historical data.

[0021] Compared with the existing technology, the outstanding features of this invention are:

[0022] 1. This invention uses a positioning plate to project the laser line emitted by the laser emitter into a light spot onto the CCD sensor, avoiding direct laser irradiation on the CCD sensor and extending its lifespan. 2. Employing the laser triangulation principle, the laser emitter and CCD sensor are arranged on the same support frame, facilitating the adjustment of the laser emission angle by construction personnel and solving the problem of the small light-receiving area of ​​CCD devices making installation and debugging inconvenient. 3. By transmitting the light spot position signal to the main server, simultaneous monitoring of multiple monitoring points is achieved, resulting in a high degree of integration and facilitating centralized management by administrators. 4. By storing the light spot position signal in a database according to the time dimension, administrators can easily query historical records, obtain graphs and reports generated from historical data, and facilitate supervision.

[0028] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0029] like Figures 1 to 4 As shown, a high-support formwork displacement monitoring system includes several data acquisition modules A and a central communication module 10 connected to the data acquisition modules A. Each data acquisition module A includes an acquisition controller and a monitoring component A1 connected to the acquisition controller. The monitoring component A1 includes a laser emitter 1 and a CCD sensor 2, and also includes a support frame 15. The monitoring component A1 is detachably connected to the support frame 15. A positioning plate 14 is installed at the monitored point. The laser emitter 1 emits a laser beam a1 towards the monitored point, which is projected onto the positioning plate 14 to form a light spot. The light spot is projected onto the CCD sensor 2. The system also includes a smart construction site management platform B. The CCD sensor 2 transmits the light spot position signal to the acquisition controller. The controller transmits the optical spot position signal to the smart construction site management platform B through the main station communication module 10. The smart construction site management platform B includes a main server 11 connected to the main station communication module 10. The main server 11 is connected to a database 12, a large display screen 20, and an alarm module 19. It can be connected to conventional IoT terminals and has various secondary IoT analog or digital interconnection development functions. Through the smart construction site management platform B, multiple points can be monitored simultaneously, and the monitoring data can be stored in the database 12 for later query. It can generate graphs and reports for managers to view on the large display screen 20, and has the function of transmitting monitoring status and alarm information in real time with mobile terminals 13 (mobile phones, tablets, etc.). The CCD sensor 2 uses a Toshiba TCD1209D linear image sensor with a 14µm pixel size. The measurement distance ranges from 10mm to 400mm, and the measurement sampling accuracy reaches 400µm, fully meeting the on-site requirements. The minimum sampling period of the CCD sensor 2 can be set to 200ns. In this embodiment, the sampling periods of both the laser emitter 1 and the CCD sensor 2 are set to 100ms. The positioning plate 14 uses a white magnetic sticker, which is attached to the monitored point. This embodiment utilizes the principle of triangulation displacement imaging measurement. The laser irradiates the positioning plate 14 to form a light spot. When the monitored point moves along the laser beam a1 direction, the measurement result changes, thus achieving laser-based displacement measurement of the object. The alarm module 19 includes a buzzer and a warning light. Alarm methods include buzzer sounding, warning light flashing, display on the large screen 20, and display on the mobile terminal 13.

[0030] Furthermore, it also includes an optical zoom filter 18, which is located between the positioning plate 14 and the CCD sensor 2. The optical zoom filter 18 is a combination of an optical focusing lens and a laser wave filtering lens, used to filter out other spectra and only allow the laser to pass through, and to focus the laser point on the working surface of the CCD sensor 2 through zoom.

[0031] Furthermore, the support frame 15 includes a monitoring component A1 support frame for mounting the monitoring component A1, a filter support frame for mounting the optical zoom filter 18, and a positioning plate support frame for mounting the positioning plate 14; a support plate 16 is provided on the monitoring component A1 support frame 15, and the support plate 16 has an isosceles triangular recessed mounting groove, on which the laser emitter 1 and the CCD sensor 2 are respectively mounted on the two sides of the mounting groove.

[0032] Furthermore, each monitoring component A1 support frame 15 is provided with two support plates 16, which are arranged in a T-shape; the laser emitter 1 includes a first emitter and a second emitter, and the CCD sensor 2 includes a first sensor and a second sensor; the first emitter and the first sensor are installed in the mounting slot of one of the support plates 16, and the second emitter and the second sensor are installed in the mounting slot of the other support plate 16.

[0033] Furthermore, the data acquisition controller includes a data acquisition processor 3, which is connected to a signal conditioning circuit 4, a transmission control circuit 5, a register output circuit 6, a DA conversion circuit 7, a shaping and filtering circuit 8, and a substation wireless network communication unit 9. The signal conditioning circuit 4 is communicatively connected to the CCD sensor 2, the transmission control circuit 5 is communicatively connected to the laser emitter 1, and the substation wireless network communication unit 9 is communicatively connected to the main station communication module 10. The data acquisition processor 3 uses an STM32F103RB microprocessor and also integrates a 12-bit four-channel analog signal acquisition module (AI-4AI-TO485). The analog signal acquisition module's input can simultaneously receive multiple position information from the CCD sensor 2. The analog signal acquisition module also has two switch outputs for on-site alarm use, and the output of the analog signal acquisition module is a standard Modbus signal. The RTU protocol is compatible with LORA terminals and connects to the LORA wireless communication module using the 485 serial mode. The advantages of this signal transmission method are long transmission distance, strong anti-interference capability, and effective prevention of power supply noise and environmental electromagnetic interference at the construction site. The register output circuit 6 uses an ADC9224 register, a 12-bit high-efficiency analog-to-digital converter register, to receive the composite signal sampled by the acquisition processor 3 from the CCD sensor 2, perform binarization processing, and retain valid digital information. The DA conversion circuit 7 is a 12-bit digital-to-analog converter that further converts the binary data from the register output circuit 6 into a linear analog signal, aiming to improve information agility and compatibility. The processed signal is output as an analog quantity from 0V to 5V. The shaping and filtering circuit 8 uses an LC circuit type low-pass filter to block the passage of high-frequency pulses and other high-frequency harmonic components, making the analog signal more realistic and stable, and improving anti-interference capability. During operation, the acquisition processor 3 generates a drive pulse, which drives the CCD sensor 2 to work after level conversion. The photosensitive unit of the CCD sensor 2 is excited by light and generates an electrical signal. Under the action of the drive pulse, it outputs a discrete analog signal. After signal filtering and amplification, the signal passes through the DA conversion circuit 7. Then, the acquisition processor 3 reads the conversion result of the DA conversion circuit 7 and stores it in the RAM of the acquisition processor 3.

[0034] Furthermore, the acquisition processor 3, signal conditioning circuit 4, transmission control circuit 5, register output circuit 6, DA conversion circuit 7, shaping and filtering circuit 8, and substation wireless network communication unit 9 are integrated on the same circuit board. The purpose is to ensure that these circuit devices work stably on the same integrated circuit board and are easy to debug.

[0035] Furthermore, the substation wireless network communication unit 9 and the main station communication module 10 adopt the LORA wireless communication module; the LORA wireless communication module is a new type of expandable data communication module. In this example, the communication module with model UG87-LoRa is used. It has the characteristic of connecting with various existing Internet of Things and computer systems, and can be directly connected to the on-site smart construction site network. Its access data information can be transmitted to various interfaces of the server without loss or delay, which can ensure real-time accuracy for monitoring in this example.

[0036] The present invention also provides a method for monitoring the displacement of high formwork, which uses a high formwork displacement monitoring device and includes the following steps:

[0037] S1, Install support frame 15: A positioning plate support frame for installing positioning plates 14 is installed at the monitored point of the high formwork scaffold 17. The high formwork scaffold 17 includes scaffold uprights 1702 and scaffold horizontal bars 1701. The positioning plate support frame is made of horizontally set angle steel and vertical plates welded to the angle steel. It is connected to the high formwork scaffold uprights 1702 by U-shaped clamps. The angle steel is set perpendicular to the scaffold uprights. There is a U-shaped clamp at each end of the angle steel. The two U-shaped clamps are connected to two uprights spaced 1-4 times apart. Two positioning plates 14 are provided, one is attached to the angle steel, and the other... Adsorbed onto the vertical plate; a monitoring component A1 support frame for monitoring the relative position change within the high formwork scaffold 17 is set at the monitoring point of the high formwork scaffold 17. It is made of a connecting rod and a T-shaped plate connected to the connecting rod. The connecting rod is connected to the high formwork scaffold upright 1702 by a U-shaped clamp. Support plates 16 are provided on the horizontal and vertical plates of the T-shaped plate. The laser emitter 1 and CCD sensor 2 are installed on the support plate 16 so that the laser beam a1 emitted by the laser emitter 1 can be projected onto the positioning plate 14 to form a light spot. The light spot can be projected onto the photosensitive plate of the CCD sensor 2 through the light spot projection path a2.

[0038] S2, Install optical zoom filter 18: A filter support frame is set between the corresponding positioning piece 14 and the CCD sensor 2 (on the light spot projection route a2). The optical zoom filter 18 is installed on the filter support frame. The angle of the optical zoom filter 18 is adjusted to make the light spot projection clear.

[0039] S3, Data Acquisition: The acquisition processor 3 controls the laser emitter 1 to emit a laser beam onto the positioning plate 14 to form a light spot. After being filtered by the optical zoom filter 18, the light spot is projected onto the CCD sensor 2. The CCD sensor 2 transmits the light spot position signal to the signal conditioning circuit 4 of the data acquisition module A. The signal conditioning circuit 4 transmits the signal to the acquisition processor 3. The acquisition processor 3 transmits the signal to the register output circuit 6, DA conversion circuit 7, shaping and filtering circuit 8, and substation wireless network communication unit 9. The signal is then transmitted to the main server 11 of the smart construction site management platform B through the substation wireless network communication unit 9 and the main station communication module 10. The acquisition processor 3 controls the emission control circuit 5 to control the laser emission period of the laser device. The acquisition processor 3 controls the signal conditioning circuit 4 to sample the CCD sensor 2 at the same time. While emitting the laser, the acquisition processor 3 sends sampling output permission pulse information and clock signal to the CCD sensor 2. By receiving the data sent by the CCD sensor 2, one cycle of data sampling is completed. The acquisition processor 3 decomposes and processes the sampled data to obtain 12-bit data depth, which is then transmitted to the register output circuit 6.

[0040] S4: Data processing: The main server 11 of the smart construction site management platform B stores the light spot position signal into the database 12 according to the time dimension for long-term storage and retrieval; the main server 11 calculates the displacement by performing vector difference calculation between each measured light spot position signal and the initial light spot position signal. The main server 11 has preset displacement warning value and displacement alarm value. When the displacement reaches the displacement warning value and displacement alarm value, the main server 11 controls the alarm module 19 to issue a warning and alarm.

[0041] Meanwhile, administrators obtain real-time data, historical data, graphs and reports generated from historical data, and alarm information through the main server 11. The real-time data, historical data, graphs and reports generated from historical data, and alarm information are transmitted to the large display screen 20 for display.

[0042] Furthermore, step S1 also includes setting up a support frame for monitoring component A1 on the foundation to monitor the overall positional changes of the high-formwork scaffold 17, and installing another set of monitoring components A1. The detection principle of this method is that the positional information collected by the data acquisition module A will change. If the monitored point moves closer to the laser emitter 1, the analog voltage output by the data acquisition module A will decrease; if the monitored point moves away from the laser emitter 1, the analog voltage output by the data acquisition module A will increase. The change in output voltage is linearly proportional to the change in displacement. The positioning plates 14, laser emitter 1, and CCD sensor 2 installed on different scaffold uprights 1702 of the high-formwork scaffold 17 by the support frame 15 can monitor the relative displacement caused by uneven horizontal or vertical deformation of the high-formwork system. The laser emitter 1 and CCD sensor 2 installed on the foundation horizontal ground by the support frame 15, and the positioning plates 14 installed on the high-formwork scaffold uprights 1702 by the support frame 15 can monitor the overall displacement of the high-formwork system.

[0043] Furthermore, it also includes a mobile terminal 13, which can connect to the main server 11 via WIFI or hotspot to the main station communication module 10 to obtain real-time status, alarm information, and graphs and reports generated from historical data.

[0044] This invention utilizes a laser emitter 1 to emit a laser beam a1 towards a positioning plate 14 installed on a scaffold horizontal bar or scaffold vertical bar. The beam is imaged by a CCD sensor 2, and the displacement caused by the change in the position of the monitored point is calculated. The system performs real-time monitoring and alarm on a smart construction site management platform B. This monitoring method can accurately detect the displacement of high formwork during construction. When the displacement exceeds the preset maximum allowable displacement value, an alarm is issued through an alarm module 19, a large display screen 20, and a mobile terminal 13. This can effectively prevent accidents during construction and avoid direct economic losses and adverse social impacts.
