Description

Technical Field

[0001] The utility model relates to the field of structure monitoring, in particular to a low-power deflectometer system. Background Art

[0002] With the rapid development of my country's transportation facilities, the construction and use of bridges have increased dramatically. With the increase in traffic load and the increase in service life, the safety of bridges has received more and more attention from relevant management departments and technical units. The deflection of bridges is an important monitoring indicator. Traditional manual methods and automated monitoring methods have certain limitations and are difficult to meet current needs.

[0003] In recent years, deflection monitoring systems using camera image recognition technology have been used, with high accuracy and fast response speed. However, since deflection meters often use image and optical methods to monitor targets, and targets are mostly reflective or visible light, rainy and foggy weather, dark conditions, and insufficient natural light will have a negative impact on measurement. Therefore, active infrared target systems are increasingly being used.

[0004] However, the existing disturbance meter system equipped with active infrared targets requires wired power supply, which makes wiring difficult and costly during integrated construction. There is a lack of automated remote control of the active infrared targets, and the power supply is always in operation, resulting in high power consumption. Utility Model Content

[0005] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a low-power deflectometer system, aiming to solve the problems of high power consumption and great wiring difficulty of the deflectometer system in the prior art.

[0006] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] A low-power deflectometer system comprises a deflectometer, a LORA communication module and a plurality of infrared targets, wherein a radio frequency unit is arranged in the LORA communication module, the LORA communication module is connected to a micro-control circuit board via a serial port, the micro-control circuit board is located inside the deflectometer and is electrically connected to a control unit of the deflectometer, when the deflectometer is controlled by the control unit to collect data, the micro-control circuit board is used to control the LORA communication module to send a radio frequency signal, the deflectometer is used to monitor a plurality of the infrared targets, each of the infrared targets is connected to a power supply module, a LORA controller is arranged between the power supply module and the infrared target, the LORA controller is used to control the power supply of the infrared target, the LORA communication module is connected to a plurality of the LORA controllers via the radio frequency unit, the power supply module comprises a photovoltaic panel, and the photovoltaic panel is used to provide electrical energy.

[0008] Compared with the prior art, the beneficial effect of the utility model is that by setting the LORA communication module and the LORA controller, the power supply of the active infrared target can be controlled. When the disturbance meter performs monitoring and collection, the control instruction is sent through the radio frequency unit in the LORA communication module, and the LORA controller controls the infrared target to be connected to the power supply, so that the active infrared target can operate normally. When the collection is stopped, a control instruction to turn off the power is sent, so that the infrared target is no longer connected to the power supply and no longer consumes electricity, which greatly reduces energy consumption. At the same time, the LORA technology used in the LORA communication module has the characteristics of low power consumption and long transmission distance, which further reduces the power consumption of the disturbance meter system. By setting the power supply module and the photovoltaic panel in the power supply module, the consumption of traditional energy can be further reduced, and the difficulty of construction wiring can be reduced.

[0009] Furthermore, the infrared target is arranged on a side of the bridge facing the deflectometer, and the target surface of the infrared target faces the deflectometer.

[0010] Furthermore, the deflectometer is connected to a router via a network port, and the router is used to send data remotely.

[0011] Furthermore, each of the photovoltaic panels is connected to a battery.

[0012] Furthermore, the battery is connected to the corresponding infrared target, and several batteries are independent of each other.

[0013] Furthermore, a camera and a stabilizing seat are arranged on the deflectometer.

[0014] Furthermore, a 4G communication unit is provided in the router.

[0015] Furthermore, an instruction unit is provided in the LORA communication module, and the instruction unit is used to generate two instructions. BRIEF DESCRIPTION OF THE DRAWINGS

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] See also Figure 1 The low-power deflectometer system in the embodiment of the utility model includes a deflectometer 100, a LORA communication module 200 and a plurality of infrared targets 300. The infrared target 300 is arranged on the side of the bridge facing the deflectometer 100, and the target surface of the infrared target 300 faces the deflectometer 100. The deflectometer 100 is provided with a camera and a stabilizing seat. The deflectometer 100 is used to monitor a plurality of the infrared targets 300. The deflectometer 100 is connected to a router 700 through a network port. The router 700 is used to send data remotely. A 4G communication unit is arranged in the router 700. Preferably, the deflectometer 100 has an image recognition function. Through the calibration reference point information of known size, after the camera recognizes, the standard displacement value corresponding to the unit pixel is calculated to obtain the central disturbance change value of the monitoring infrared emission point, thereby measuring the deformation of the object to be measured. It can be understood that the use of the infrared target 300 can avoid the deterioration of the optical recognition effect caused by bad weather, and ensure the monitoring accuracy of the low-power disturbance meter system.

[0025] The LORA communication module 200 is connected to a micro-control circuit board via a serial port. The micro-control circuit board is located inside the deflectometer 100 and is electrically connected to the control unit of the deflectometer 100. A radio frequency unit is arranged in the LORA communication module 200. When the deflectometer is controlled by the control unit to collect data, the micro-control circuit board is used to control the LORA communication module to send a radio frequency signal. An instruction unit is arranged in the LORA communication module 200. The instruction unit is used to generate two instructions. Each of the infrared targets is connected to a power supply module. A LORA controller is arranged between the power supply module and the infrared target. The LORA controller is used to control the power supply of the infrared target. The LORA communication module is connected to the LORA controller via the radio frequency unit. The power supply module includes a photovoltaic panel. The photovoltaic panel is used to provide electrical energy. Each of the photovoltaic panels is connected to a battery. The battery is connected to the corresponding infrared target. Several batteries are independent of each other. Preferably, the two types of instructions are a power-on instruction and a power-off instruction. When the deflection meter 100 is monitoring and collecting, the staff operates the control unit to control the deflection meter 100 to run various commands, and at the same time connects the LORA communication module through the micro-control circuit board to make the LORA communication module start operating synchronously. The power-on instruction is sent through the radio frequency unit in the LORA communication module 200, and the LORA controller 400 controls the infrared target 300 to be connected to the power supply. The active infrared target 300 can operate normally to collect data; when the collection is stopped, a shutdown instruction is sent so that the infrared target 300 is no longer connected to the power supply, thereby greatly saving energy. It can be understood that the LORA technology used in the LORA communication module 200 has the characteristics of low power consumption and long transmission distance, which further reduces the power consumption of the low-power interference meter system. The photovoltaic panel 600 is arranged in the power supply module to charge the battery 500, further reducing the consumption of traditional energy. Moreover, since the lines between the several infrared targets 300 are independent of each other, the power supply module connected to itself can complete power-on and monitoring, which greatly reduces the difficulty of construction wiring and reduces the construction wiring cost.
