Embodiment 1

[0050] This embodiment provides a fall warning device, figure 1 It is a structural diagram of a fall warning device according to an embodiment of the present invention, such as figure 1 As shown, the fall warning device includes:

[0051]Tension wire 1, the first end of which is connected to the first end of tension sensor 2, and the second end thereof is fixed on the object to be measured 4, the tension on the tension wire 1 varies with the inclination angle of the object to be measured. In this embodiment, the tension line 1 may have elastic force, can be stretched and shortened, or may not have elastic force, which is not specifically limited here. In addition, in order to ensure uniform force, the number of tension lines 1 can be set to two or two As mentioned above, the corresponding tension sensor can also be set to more than two; the fall warning device also includes: a tension sensor 2, the second end of which is fixed on the bracket 5 for placing the object to be mea...

Embodiment 2

[0056] This embodiment provides another fall warning device, Figure 4 It is a structural diagram of a tension sensor according to an embodiment of the present invention, such as Figure 4 As shown, the tension sensor includes: a variable resistor 21 and a slider 22, the variable resistor 21 is non-electrically connected to the bracket 5, the slider 22 is connected to the tension line 1, and when the tension of the slider 22 on the tension line changes , is pulled to change the position, and then change the resistance value of the variable resistor 21.

[0057] The tension sensor 2 also includes a voltage dividing resistor 23 and a first power supply Vcc1, and the variable resistor 21 is connected in series with the first power supply Vcc1 and the voltage dividing resistor 23 to form a first conductive loop.

[0058] Figure 5 It is the working principle diagram of the tension sensor according to the embodiment of the present invention, such as Figure 5 As shown, when the ...

Embodiment 3

[0067] This embodiment provides another fall warning device, such as the above Figure 7 As shown in , by setting a voltage-current conversion circuit (the voltage monitoring module 31 in the above-mentioned embodiment) on the main board (the main control circuit 3 in the above-mentioned embodiment), the tension wire 1 connected to the object under test is detected by the voltage-current conversion circuit The pulling force information on the device can judge the position of the object under test, and can predict the fall of the object under test online at any time.

[0068] Normal state: At this time, the tension on the tension line is a normal value, and the main board collects the sampling voltage at this time to judge that there is no risk of the object under test falling.

[0069] Moving and tilting state: the object to be tested moves, the tension line 1 is stretched, and the tension becomes larger. The slider 22 in the tension sensor 2 changes position after being pulle...

Abstract

The invention discloses a falling early warning device and method and air conditioning equipment. The falling early warning device comprises a tension line, a tension sensor and a main control circuit. The first end of the tension line is connected with the first end of the tension sensor, the second end of the tension line is fixed to an object to be measured, and the tension on the tension linechanges along with the change of the inclination angle of the object to be measured. The second end of the tension sensor is fixed to a bracket of the object to be measured and is used for monitoringthe change of the tension on the tension line. And the main control circuit is used for sending out an early warning signal according to the change of the tension on the tension line. According to thefalling early warning device and method and the air conditioning equipment, the inclination condition of the to-be-measured object can be monitored in real time by monitoring the change of the tension on the tension line, so that early warning information is sent out before the to-be-measured object falls, maintenance personnel are prompted to handle in time, and safety accidents or economic losses are avoided.

Description

technical field [0001] The present invention relates to the technical field of danger warning, in particular to a fall warning device, method and air conditioning equipment. Background technique [0002] In life, the phenomenon of falling objects from heights happens from time to time. For example, most of the outdoor units of household air conditioners are installed on the outer walls of high-rise buildings, and accidents of falling from high altitudes may occur. [0003] At present, the installation of the outdoor unit is mainly fixed by a special fixing frame or placed on the beam of the building. After that, there will be no regular inspection of whether the outdoor unit is loose or falling off. It is impossible to monitor the fall of the outdoor unit. Once it falls, the loss will be very serious . It is also impossible to predict the fall of the home unit. It can be seen that in the existing technology, after the air conditioner unit is installed and fixed at high al...
