The structure is simple and compact, the design is ingenious and flexible, and it can rotate at a certain angle on the spherical surface to achieve universal adjustment of the angle of adjacent guardrail frames, increase the use occasions of the guardrail, and have a better use effect.

[0027] As a guardrail with posture change alarm function in an embodiment of the present invention, further, the spherical strain shell is made of a quarter to a quarter three-sphere spherical shell, and is arranged on the inner ball head according to actual usage. The strain shell rotates at an angle to cooperate with each other to achieve universal adjustment of the angle of adjacent guardrail frames.

[0028] As a guardrail with posture change alarm function in an embodiment of the present invention, further, a strain gauge is arranged in the inner ball head; the middle of the spherical strain shell and the inner ball head are both provided with a steel wire through hole for connecting the strain gauge; the strain gauge is electrically connected to the alarm device. The strain gauge is fixed by a steel wire and connected to the alarm device, and the posture information of the adjacent guardrail such as tilt, distortion, and external force impact is collected through the strain gauge to improve the protection and alarm performance of the guardrail.

[0029] As a guardrail with posture change alarm function in an embodiment of the present invention, further, the spring adopts a tower spring or a compression spring to achieve elastic connection such as shock absorption between adjacent guardrail frames.

[0032] Furthermore, the embodiment of the present invention also provides a guardrail posture change warning method, see Figure 3 As shown, based on the above-mentioned guardrail with posture change alarm function, the implementation process includes the following contents: after the guardrail is installed, it enters the working state, collects the initial balance state of the guardrail frame and the tension at the hinges of the head and tail guardrail frames; when the guardrail frame is moved, the real-time collected guardrail frame balance state and hinge tension data are matched with the preset alarm threshold range; when the preset alarm threshold range is exceeded, the alarm device is triggered.

[0034] The guardrail frame is equipped with an angle sensor and an alarm device with an integrated power module connected by a signal and power transmission line. The guardrail frame can also be set as an elastic retractable guardrail frame or a Figure 1 The structure shown in FIG. 1 is a structure in which multiple connecting rods are welded and fixed to each other horizontally and / or vertically; at least two elastic connecting members may be provided at both ends of adjacent guardrail frames, see Figure 1 and 2 As shown, the elastic connector connects two sets of guardrail frames into one by cooperating with the spherical strain shell and the inner ball head inside the spherical strain shell. A steel wire is set inside the spherical strain shell and the inner ball head to penetrate the spherical strain shell and the inner ball head. A strain gauge is installed on the steel wire inside the inner ball head. The signal output of the strain gauge is connected to the alarm device through the signal and power transmission line. In order to accurately define the posture of the guardrail frame so that it can be kept in a reasonable position, the preset warning threshold angle control range of the angle sensor can be ±5 to ±10 degrees with the horizontal plane. In order to make the alarm function of the guardrail easy to realize, the preset warning threshold strain range of the strain gauge can be controlled to be 150 to 250 Newtons after the tension value is amplified by the amplifier. After the guardrail frame is connected and installed into a guardrail through the spherical connector and the elastic base, the current guardrail position information and the unique identification code are bound, the electronic equipment enters the working state, and the sensor records the initial guardrail balance state and the tension state of the connection; when the guardrail is moved, the angle sensor will feel that the guardrail balance state and the tension state of the strain gauge at the spherical connection will also change. If the preset threshold is exceeded (the change in tension exceeds 150 to 250 Newtons (N), or the angle between the fence and the ground exceeds ±5 to ±10), the alarm device is turned on. On the one hand, the guardrail emits a warning sound, and on the other hand, an alarm message is sent to the relevant department. The original position of the moved guardrail can be determined based on its identification code. It is also possible to accurately determine which section of the guardrail frame has a problem. The guardrail is connected by a spherical hinge and cannot be disassembled without special tools. Generally, it can only be removed after the guardrail frame is removed. Therefore, it is fixed reliably. The angle sensor, strain gauge and alarm realize the alarm and protection functions of the guardrail frame tilting, twisting, external force impact, human climbing, moving and other posture changes. It has a simple structure and is easy to install. It has good practicality and promotion and application value.
