Problems solved by technology

[0002] In daily life, many low-rise building residents have installed anti-theft windows on the windows on the outer walls to prevent theft, but the residents in slightly higher buildings do not have anti-theft security windows. In reality, the anti-theft windows on the lower floors just provide a platform for climbers to climb to the homes of high-rise residents, which will cause personal and property losses to the residents. It was not discovered on the spot, and after the climber left, it was impossible to find favorable evidence to determine the identity of the climber, which caused certain difficulties for the subsequent property recovery work and the arrest of criminals
At present, there are also some anti-climbing monitoring devices, and these anti-climbing monitoring devices generally use infrared to monitor. Several parallel infrared rays are sent by infrared transmitters and received by infrared receivers. When it is on the outer wall, it will block the transmission of the corresponding infrared rays, so that the infrared signal is interrupted, and the alarm host will receive the open circuit signal, thus sending out an alarm
However, this monitoring device has the following disadvantages: 1. Infrared monitoring will be affected by sunlight, and the false alarm rate is high; 2. Some small objects such as leaves, small animals, etc. will also block infrared rays, and the system will mistakenly think it is a person, which will cause false alarm

Embodiment 1

[0033] Such as Figure 1 to Figure 4 As shown, a building anti-climbing monitoring device includes a housing 1, and the housing 1 is fixedly installed on the outer wall of the building above the second floor and below the top floor, and the distance between the installation position of the housing 1 and the easy-to-climb object is greater than 0.5 m.

[0034] A PCB board is fixed inside the housing 1, a processing chip is arranged on the PCB board, and at least a pair of ultrasonic transmitters and ultrasonic receivers used in combination are arranged on the housing 1, and the ultrasonic transmitters and the ultrasonic receivers are both It is connected to the processing chip through the PCB board. The housing 1 includes a housing, the housing is provided with an installation chamber installed on the PCB board, and the housing is symmetrically provided with two installation probes, each installation probe is equipped with the combined use of the ultrasonic transmitter detect...

Embodiment 2

[0039]This embodiment also discloses a building anti-climbing monitoring method, including the following steps:

[0040] A. An ultrasonic monitoring device is installed on the outer wall above the second floor and below the top floor of the building. The ultrasonic monitoring device has an ultrasonic generator, an ultrasonic receiver, a waveform processing chip and a storage unit; the ultrasonic monitoring device is connected to the alarm host. The location of the device should not be close to the sewer pipe or other climbing objects on the outer wall;

[0041] B. The monitoring distance of the ultrasonic transmitter is set as L, and the monitoring distance L is divided into N equal-length monitoring sections, N is a natural number greater than 3, and each monitoring section consists of a plurality of cross-sectional planes perpendicular to the ultrasonic transmission route 4 components, the section plane 4 of each monitoring section is divided into several monitoring grids 6,...

Embodiment 3

[0048] This embodiment is basically similar to the method of embodiment 2, wherein, step B1 can also be used to replace in the described step B, and its step B1 is: the monitoring distance of setting ultrasonic transmitter is L, this monitoring distance L is divided into N equal-length monitoring sections, N is a natural number greater than 3, each monitoring section is composed of a plurality of sectional planes 4 perpendicular to the ultrasonic transmission route, and the sectional planes 4 of each monitoring section are divided into several monitoring grids 6, The monitoring grids 6 divided by each sectional plane 4 in the same monitoring section are equal, and the number of monitoring grids 6 divided by the sectional planes 4 of each monitoring section increases from near to far and forms an arithmetic sequence. At this time, in the corresponding step E The setting method of the preset grid number of section plane 4 is as follows: the preset grid numbers in the same monitor...

Abstract

The invention discloses a building anti-climbing monitoring device. The building anti-climbing monitoring device includes a housing; wherein the housing is fixed to an outside wall between a second floor of a building and a top floor of the building; a distance between an installation position of the housing and an object easy to climb is greater than 0.5 m; a PCB is fixed within the housing, and the PCB is provided with a processing chip; the housing is provided with at least one pair of combining ultrasonic emitter and ultrasonic receiver, and the ultrasonic emitter and the ultrasonic receiver are connected to the processing chip by the PCB. According to the building anti-climbing monitoring device in the invention, ultrasonic wave is used for detection, the ultrasonic wave can penetrate a thin object and cannot be affected by an external environment, the ultrasonic wave has reflection and receiving time, and high falling objects can be quickly excluded from a monitoring range, so that a monitoring result of the building anti-climbing monitoring device is more accurate.

technical field [0001] The invention relates to an anti-climbing monitoring device and also designs an anti-climbing monitoring method. Background technique [0002] In daily life, in order to prevent theft, many low-rise building residents install anti-theft windows on the windows on the outer walls, but the slightly higher building residents do not have anti-theft windows. In practice, the low-rise anti-theft windows are just for climbing A platform for climbers to climb to the high-rise residents’ homes, which will cause personal and property losses to the residents, and when the climbers leave after entering the house to commit crimes, if they are not found on the spot, after the climbers leave, they will not be able to find a favorable place. Evidence confirms the identity of the climber, which creates certain difficulties for subsequent property recovery work and the arrest of criminals. At present, there are also some anti-climbing monitoring devices, and these anti-...
