Description

Technical Field

[0001] The present invention relates to the technical field of building safety monitoring, and particularly to a high formwork monitoring application system based on wireless technologies of LoRa and 4G links. Background Art

[0002] With the increase in the number of high-rise buildings, there have emerged high-rise building types with relatively unique high-structure designs and large spans. For these types of buildings, one of the widely applied construction techniques is the high formwork construction technique, which mainly serves as an important support system in modern high-rise buildings. The application of this construction technique can effectively ensure the quality and safety during the construction of such buildings, but at the same time, it also poses extremely high requirements for the construction load capacity, erection span, etc. In view of the suddenness and severity of high formwork safety, it is necessary to conduct safety monitoring on high formwork.

[0003] In the existing high formwork systems, the stability of data upload is not high. Most of them collect data through wired means and then upload the data through a data collector. Due to the harsh environment at the construction site, too many lines result in low stability of device data. At the same time, among the wireless devices that have emerged on the market one after another, most of them have a single data upload mode, which cannot reflect the reliability of the data. Especially in a harsh environment, data interruption often causes serious consequences.

[0004] To solve the above problems, it is particularly necessary to design a high formwork monitoring application system based on wireless technologies of LoRa and 4G links. Summary of the Invention

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a high formwork monitoring application system, which can improve the stability of the system, has higher data reliability, and thus plays a warning role in improving the safe construction of the project and is easy to promote and use.

Based on the above hardware, software logic is carried, and multiple sensors of the system are cascaded and applied. The integrated wireless tilt settlement sensor, the integrated wireless load sensor, and the wireless sound and light alarm respectively upload the collected data independently to the cloud server. The connectivity is tested by judging the data returned by the cloud server. If the data cannot be uploaded to the cloud server, the data is sent to the wireless gateway through the local lora for reissuing; if there is no gateway in the system, each sensor acts as a node for data transmission; when the data cannot be uploaded to the cloud server, the data collected by itself is transmitted to the sensor with the adjacent number. If this sensor cannot connect to the network, this sensor will transmit the data to the next numbered sensor until it is uploaded to the network.

[0007] The integrated wireless tilt settlement sensor includes a tilt settlement main control module, a tilt settlement storage module, a tilt settlement power supply module, a tilt settlement communication module, and a sensor module. The tilt settlement communication module adopts a two-stage upload method of 4G and Lora. The sensor module includes a wire-pulling sensor for measuring the linear displacement of the building and an inclinometer chip for measuring the tilt angle of the building.

[0008] The integrated wireless load sensor includes a load main control module, a load storage module, a load power supply module, a load communication module, and a load module. The load module is used to collect load parameters, and the load communication module adopts a two-stage upload method of 4G and Lora.

[0009] The wireless sound and light alarm includes a sound and light alarm main control module, a sound and light alarm storage module, a sound and light alarm power supply module, a sound and light alarm communication module, and a sound and light alarm module. The sound and light alarm communication module adopts a two-stage upload method of 4G and Lora; the wireless sound and light alarm needs to monitor each device on site in real time, so lora is used for alarm setting. Through this method, the delay can be responded in time within 5ms.

[0010] The wireless gateway includes a gateway main control module, a gateway storage module, a gateway power supply module, and a gateway communication module. The gateway communication module adopts a two-stage transmission method of 4G and Lora.

[0011] Preferably, the inclinometer chip of the integrated wireless tilt settlement sensor includes an X-axis, a Y-axis, and a Z-axis for tilt measurement. The integrated wireless tilt settlement sensor also has the function of collecting an encoder and has integrated monitoring to meet the existing monitoring specifications.

[0012] Preferably, the load module of the integrated wireless load sensor includes a strain gauge for testing the load of building concrete and steel structures, and a signal processing circuit, which converts analog quantities into digital quantities through AD analog-to-digital conversion for the load main control module to collect load parameters.

[0013] Preferably, the wireless sound and light alarm controls the on and off of the sound and light alarm module through switch quantity conversion to give an early warning, and the sound and light alarm module includes a buzzer and an LED light.

[0014] Preferably, the wireless gateway is mainly used for data communication, and its gateway communication module includes four groups of lora modules for monitoring sensors, three of which are used to monitor three types of sensors, namely two integrated wireless tilt and settlement sensors including horizontal displacement and digital vertical displacement and one integrated wireless load sensor, and the other group monitors wireless sound and light alarms.

[0015] A method for applying a high-support formwork monitoring application system, the steps of which are: configuring various types of sensors, such as an integrated wireless tilt settlement sensor, an integrated wireless load sensor, and a wireless sound and light alarm, through a handheld terminal tablet, numbering the monitoring points, and repeatedly configuring multiple points; Each sensor tests connectivity during the acquisition phase, and determines through the cloud server whether the sensor can upload its own data through the 4G network. During this phase, if one or more sensors are offline in the cloud server, the wireless gateway detects the signal through Lora, starts the Lora mode for multi-point device connection, collects data into each storage module in the local area network, and continues to resend the data to the cloud server through 4G. The resent data is classified according to the previous numbering and placed in the database; At the same time, in this system, when an alarm occurs in a certain data, lora is used to send the alarm signal to the nearest wireless sound and light alarm. The wireless sound and light alarm receives the signal in the local area network and provides real-time on-site alarm function. If there is no wireless gateway on site, the devices will be numbered step by step. During the data collection process, if the cloud server is suddenly disconnected, the data will be transmitted by looking for the next cascade device. After the next cascade device receives the data, it will store the data and then send it to the cloud server. And so on, the data will be finally uploaded to the cloud server.

[0016] The beneficial effects of the present invention are as follows: the system can monitor the settlement, inclination, load and horizontal displacement of buildings in real time, realize the synchronous data collection of multiple measuring points, upload information through two links, improve the stability of the system, and make the data more reliable, thereby improving the safety of engineering construction and playing an early warning role, and has broad application prospects.

Specific embodiments

[0018] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] Referring to Figure 1-6 , this specific embodiment adopts the following technical solution: A high formwork monitoring application system includes an integrated wireless tilt settlement sensor, an integrated wireless load sensor, a wireless sound and light alarm, and a wireless gateway. Based on the above hardware, software logic is carried. The system cascades multiple sensors for application. The integrated wireless tilt settlement sensor, the integrated wireless load sensor, and the wireless sound and light alarm independently upload the collected data to the cloud server. The connectivity is tested by judging the data returned by the cloud server. The data that cannot be uploaded to the cloud server is sent to the wireless gateway through the local Lora. By testing, the transmission distance of Lora in the local area is 5 km. The gateway can be placed in a place with good signal to reissue the data. If there is no gateway in the system, each sensor acts as a node for data transmission; when the data cannot be uploaded to the cloud server, the data collected by itself is transmitted to the sensor with the adjacent number. If this sensor cannot connect to the network, this sensor will transmit to the next numbered sensor until it is uploaded to the network.

[0020] The integrated wireless tilt settlement sensor in this specific embodiment includes a tilt settlement main control module, a tilt settlement storage module, a tilt settlement power supply module, a tilt settlement communication module, and a sensor module. The tilt settlement communication module adopts a two-stage upload method of 4G and Lora. The sensor module includes a wire-pulling sensor for measuring the linear displacement of the building and an inclination angle chip for measuring the inclination angle of the building. The inclination angle chip includes an X-axis, a Y-axis, and a Z-axis for tilt measurement; this integrated wireless tilt settlement sensor also has the function of collecting an encoder and has integrated monitoring to meet the existing monitoring specifications.

[0021] The integrated wireless load sensor includes a load main control module, a load storage module, a load power supply module, a load communication module and a load module. The load module is used to collect load parameters, including strain gauges for testing the loads of building concrete and steel structures, and a signal processing circuit. The signal processing circuit converts analog signals into digital signals through AD analog-to-digital conversion for the load main control module to collect load parameters. The load communication module uses a two-stage upload method of 4G and Lora.

[0022] The wireless acoustic-optic alarm includes an acoustic-optic alarm main control module, an acoustic-optic alarm storage module, an acoustic-optic alarm power supply module, an acoustic-optic alarm communication module and an acoustic-optic alarm module. The acoustic-optic alarm communication module uses a two-stage upload method of 4G and Lora. The wireless acoustic-optic alarm controls the on-off of the acoustic-optic alarm module through switch quantity conversion for early warning. The acoustic-optic alarm module includes a buzzer and an LED lamp. Since the wireless acoustic-optic alarm needs to monitor various on-site devices in real time, Lora is used for alarm setting. Through this method, the delay can be responded to in time within 5ms.

[0023] The wireless gateway is mainly for data communication and includes a gateway main control module, a gateway storage module, a gateway power supply module, and a gateway communication module. The gateway communication module uses a two-stage transmission method of 4G and Lora. The gateway communication module includes four groups of Lora modules for monitoring sensors. Among them, three groups are used to monitor three types of sensors, namely two integrated wireless tilt settlement sensors including horizontal displacement and vertical displacement, and one integrated wireless load sensor. The other group monitors the wireless acoustic-optic alarm.

[0024] This specific embodiment also provides a method for applying a high formwork monitoring application system. The steps are as follows: various types of sensors such as integrated wireless tilt settlement sensors, integrated wireless load sensors, and wireless acoustic-optic alarms are configured through a handheld terminal tablet, the monitoring points are numbered, and multi-point repeated configuration is performed; During the acquisition phase, each sensor tests its connectivity. The cloud server determines whether the sensors can upload their respective data via the 4G network. In this phase, if one or more sensors are disconnected from the cloud server, the wireless gateway detects the signal via LoRa and activates the LoRa mode for multi-point device connection. Within the local area network, the data is collected into each storage module and will continue to be retransmitted to the cloud server via 4G. The retransmitted data is classified according to the previous numbers and placed in the database. The delay is within 1s, that is, the data only requires a second-level response during the disconnection and reconnection process, greatly improving the stability of the system. Meanwhile, in this system, when an alarm occurs for a certain piece of data, the alarm signal is sent to the nearest wireless audible and visual alarm via LoRa. The wireless audible and visual alarm provides on-site alarm function in real time when receiving the signal within the local area network; If there is no wireless gateway on-site, the devices are numbered step by step. During the data acquisition process, if the connection to the cloud server is suddenly interrupted, data transmission is carried out by finding the next cascaded device. After receiving the data, the next cascaded device stores the data and then sends it to the cloud server, and so on, until the data is finally uploaded to the cloud server.

[0025] This specific implementation combines multiple on-site application scenarios and provides three different modes under different conditions. That is, in an environment with a public network, each sensor can freely upload data via 4G. When in an enclosed space, if communication problems occur and data cannot be transmitted via the public network, data can be uploaded through cascading. In the case of a gateway, the gateway is used as a repeater for data retransmission.

[0026] This system is used for building safety monitoring, which can monitor building settlement, inclination, load, and horizontal displacement in real time. At the same time, through the Internet of Things node transmission technology, various sensors can be combined in any way. Two types of links are provided for information upload between sensors, improving the stability of the system. The maximum effective star link of this system is up to 16 groups, that is, 64 sensors, realizing synchronous acquisition work for multiple measuring points, improving the acquisition frequency and stability at the same time, and having higher data reliability, with broad market application prospects.

[0027] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
