Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.
The schematic diagram of the distribution of the climbing nails of the communication iron tower is shown in fig. 1, the climbing nails on the communication iron tower are arranged in left and right rows, and the heights of the left and right climbing nails are staggered, so that the climbing nails are distributed in a zigzag mode integrally. When the personnel climb the tower, the left and right feet are commonly stepped on the left and right two and climb the nail, and the left and right hands climb on the other layer of two and climb upwards in proper order. In the process of climbing the tower, at least two climbing nails can be contacted at a certain moment.
The installation schematic diagram of the climbing nail of the communication iron tower is shown in fig. 2, and the climbing nail is clamped by two bolts and fixed on the tower body.
The personnel tower-climbing monitoring device provided by the invention consists of a plurality of contact pressure detection terminals arranged on the creeping nails and a monitoring main control module; the touch pressure detection terminal comprises a fastening structure 1 and a transmission cover 2, and a schematic diagram of the touch pressure detection terminal installed on the creeping nail is shown in figure 3.
The fastening structure is shown in fig. 4, and includes a fastening body 101, a clamping block 102, a proximity switch 103, and a return spring 104. The fastening body 101 and the clamping block 102 enclose the climbing nail from the upper and lower sides, respectively, and are fixed by screws, so that the climbing nail is clamped between the fastening body 101 and the clamping block 102. The proximity switch 103 is fixed to the right side of the fastening body 101; the return spring 104 is placed from above into a counter bore in the right side of the fastening body 101 and protrudes out of the fastening body 101 for supporting the transmission housing 2. The fastening body 101 has a pin hole 105 at the upper left corner.
Wherein the transmission housing 2 is housed on the fastening structure 1 as shown in fig. 5. The right side of the transmission cover 2 is provided with a bulge, so that the tower climbing personnel can be prevented from touching and pressing, and particularly, the transmission cover 2 slides outwards when being stepped by feet, and a certain protection effect is achieved.
As shown in fig. 3, the through hole 201 at the upper left corner of the transmission cover 2 is aligned with the pin hole 105 on the fastening body 101 and a pin is inserted so that the fastening body 101 and the transmission cover 2 can rotate around the pin. In this example, the transmission cover 2 is made of metal.
When the foot of a person climbing the tower steps on the transmission cover 2 of the touch detection terminal, the transmission cover 2 rotates downwards with the center of the pin shaft, the reset spring 104 is pressed to deform and contract, and when the transmission cover 2 is close to the proximity switch 103, the proximity switch 103 is triggered to send touched information to the monitoring main control module. When the transmission cover 2 is free from external force, the reset spring 104 stretches to lift the right end of the transmission cover 2, so that the inner wall of the transmission cover 2 is far away from the proximity switch 103, and the proximity switch 103 is not triggered.
The monitoring main control module is connected with each touch pressure detection terminal through a data line; the plurality of touch pressure detection terminals are correspondingly arranged on a plurality of continuous creeping nails of the communication iron tower one by one.
The method for judging whether the personnel climb the tower by the monitoring main control module comprises the following steps: when two or more touch pressure detection terminals are touched and pressed from the data line, the person is determined to climb the tower; when the positions of the detection terminals which are sequentially touched and pressed within the specified time are from bottom to top, the state that the personnel get on the tower is judged; when the positions of the detection terminals sequentially pressed within a predetermined time are from top to bottom, it is determined that the person is in a tower-falling state.
When the upper tower state or the lower tower state is judged, all detection devices are not required to be detected to be pressed, and only most detection devices are required to be detected. For example, when the number of the touch detection terminals of the device is 3, generally only 2 touch detection terminals are detected, and the upper tower state and the lower tower state can be determined according to the trigger sequence.
According to the monitoring device for the person climbing the tower, disclosed by the invention, according to the climbing characteristics of the person, a mechanical structure is adopted to detect the contact pressure condition, and the person is determined to climb the tower when the condition that two climbing nails have contact pressures is detected at the same time. And simultaneously, whether the personnel goes up the tower or goes down the tower can be judged. The device has good structural stability and is not easy to cause false alarm.
As a preferable scheme of the invention, the number of the touch pressure detection terminals of the device is 3, and the touch pressure detection terminals are arranged on two left crawl nails and two right crawl nails which are arranged on three continuous layers. Generally, the distance between the climbing nails of the communication iron tower is generally 60 centimeters, the distance between the climbing nails at the left side and the right side is generally 40 centimeters, and people going up the tower cannot cross one climbing nail when climbing the tower, so that at least 2 touch pressure detection terminals are needed. However, considering that the outdoor environment is complex, and considering that a touch pressure detection terminal may be failed, 3 devices are installed in series in practical use, as shown in fig. 6. Therefore, the cost can be reduced, and effective detection is guaranteed.
As another preferable aspect of the present invention, the minimum weight of the touch sensing terminal touched is 20 kg by selecting an appropriate return spring 104. The weight of ordinary birds and cats is generally less than 20 kg, when the bird and cat stand on the touch pressure detection terminal, the transmission device of the bird and cat basically does not descend because the return spring 104 deforms slightly, the proximity switch 103 of the bird and cat is not switched on, and the bird and cat cannot send touched pressure information to the monitoring main control module. Therefore, the situation that false alarms are caused when a plurality of cats or birds stand on a plurality of touch pressure detection terminals is avoided.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment, and all technical solutions belonging to the principle of the present invention belong to the protection scope of the present invention. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
