[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] like Figures 1-4 The diagram shown is a structural diagram of a tension alarm provided in an embodiment of the present utility model, including: a mounting shell 1, the mounting shell 1 having a cavity for mounting the main control component, the mounting shell 1 having a mounting bracket 111, the mounting bracket 111 being used to mount exhibits;

[0026] The main control component includes a control board 2, a pressure probe, and a DIP switch. The control board 2 is equipped with a tensile detection unit and a photosensitive detection unit. The tensile detection unit is used to detect whether the exhibit on the mounting bracket 111 has been removed or replaced to generate an electrical signal and transmit the electrical signal to the control board 2. The photosensitive detection unit generates an electrical signal by detecting whether the light around the exhibit changes and transmits the electrical signal to the control board 2.

[0027] The pressure probe is mounted on the mounting bracket 111 and is used to detect the weight of the exhibit mounted on the mounting bracket 111. The DIP switch is mounted on the control board 2 and is used to adjust the sensitivity threshold of the light change of the photosensitive detection unit on the control board 2.

[0028] In the utility model embodiment, preferably, the tension alarm can be a wall-mounted alarm for the exhibit, which can be used for installing the exhibit and transmitting corresponding electric signals and reacting according to the state of the exhibit when the exhibit is installed in the tension alarm, so as to realize monitoring and protection of the exhibit. The tension alarm mainly comprises a mounting shell 1 and a main control assembly. The inside of the mounting shell 1 can be used for installing the main control assembly. A mounting rack 111 for installing the exhibit is arranged on the outer wall of the mounting shell 1, so that the exhibit can be hung on or fixed on the mounting rack 111. The main control assembly mainly comprises a control panel 2, a pressure probe and a dial switch. The pressure probe is installed on the mounting rack 111. The pressure probe records the gravity of the exhibit and transmits the signal to the tension detection unit of the control panel 2. When someone tries to replace or take down the exhibit, the pressure probe on the mounting rack 111 detects that the gravity changes from the gravity of the exhibit, and transmits the electric signal to the control panel 2 to issue an alarm and notify the security personnel. The sensitivity threshold of the light-sensitive detection unit can be adjusted through the dial switch. The light-sensitive detection unit issues an electric signal by detecting the change of light around the exhibit or the tension alarm. When the exhibit is moved greatly, taken down, replaced or the tension alarm is removed, the light-sensitive detection unit detects that the initial light-sensitive value when the exhibit is hung changes, and then transmits the electric signal to the control panel 2. The control panel 2 reacts and timely issues an alarm to notify the security personnel. The sensitivity threshold can be adjusted by using the dial switch, which can avoid false alarm caused by slightly blowing the exhibit, and better protect the exhibit from being damaged or stolen, so that the detection effect is good and the exhibit can be better protected.

The control panel 2 is arranged in the main control assembly. The tension detection unit on the control panel 2 detects the pressure difference formed by whether the exhibit on the mounting rack 111 is taken down or replaced to generate an electric signal and transmit the electric signal to the control panel 2. At the same time, the light-sensitive detection unit detects whether the light around the exhibit changes due to being taken down or replaced to generate an electric signal and transmit the electric signal to the control panel 2. The pressure probe is installed on the mounting rack 111 and records the gravity of the exhibit on the mounting rack 111 and transmits the signal to the control panel 2. The dial switch is arranged to adjust the sensitivity threshold of the light-sensitive detection unit to prevent false alarm caused by slightly blowing the exhibit by external wind. Not only the tension detection unit detects whether the exhibit is taken down or replaced, but also the dial switch adjusts the sensitivity threshold of the light-sensitive detection unit to prevent false alarm, so that the problem of the exhibit being damaged, stolen and poor detection effect affecting the safety of the exhibit is solved.
