DETAILED DESCRIPTION

[0019] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The present embodiment provides a prison anti-escape warning device, which is mainly used to solve the problem that the existing technology uses infrared technology to have false alarms and cannot accurately determine the location of the prisoner's escape, and provides the following technical solutions. Figure 1-Figure 7 Make a detailed description: Embodiment 1:

[0021] A prison anti-escape early warning device comprises a detection unit 1 installed on a wall, wherein the detection unit 1 is used to detect whether a prisoner approaches the wall, and the detection unit 1 is electrically connected to a control unit 2, the control unit 2 is used to receive an electrical signal transmitted by the detection unit 1, and an alarm unit 3 is used to output an alarm sound and indicate an alarm position, and the detection unit 1, the control unit 2, and the alarm unit 3 are all connected by wires.

[0022] The detection unit 1 includes an anti-overlanding roller 5 which is rotatably mounted on the wall by a bracket 4. Since the anti-overlanding roller 5 is rotatably mounted on the wall, when a prisoner wants to climb the wall, the anti-overlanding roller 5 will automatically rotate as long as it is subjected to force, so the prisoner's hands cannot exert force and it is difficult to climb up the wall, thereby preventing the prisoner from escaping. At the same time, since the prisoner grabs the anti-overlanding roller 5, a downward force is applied to the anti-overlanding roller 5. In order to detect this action, the bracket 4 is constructed in a "ㄈ" shape, and the end of the anti-overlanding roller 5 is rotatably mounted on the upper end of the notch of the bracket 4 (specifically, as shown in FIG. Figure 4 As shown), a weighing sensor 10 is installed between the upper and lower parts of the notch of the bracket 4, and the weighing sensor 10 is electrically connected to the control unit 2. When the force applied by the prisoner is detected by the weighing sensor 10, the detection signal value thereof changes greatly. When it is transmitted to the control unit 2, an alarm sound can be output (because the weight of a human body is much different from that of a bird, there is no false alarm). In addition to the power grid of the prior art, the present application also provides another anti-overrun roller 5 to prevent the prisoner from escaping. This design will not harm the prisoner. At the same time, the weighing sensor 10 is provided so that the instantaneous pulling force when the prisoner grabs the anti-overrun roller 5 causes the signal generated by the weighing sensor 10 to be given to the control unit 2, and the control unit 2 controls the alarm unit 3 to alarm.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, in this embodiment, a shielding cover 14 for shielding the weighing sensor 10 is fixed to the upper end of the bracket 4 at the top, and the shielding cover 14 is connected to the upper end surface of the notch of the bracket 4 through a T-shaped seat, as shown in FIG. Figure 4As shown, the top of the T-seat here is fixed to the inner top of the shielding cover 14 and the bottom is fixed to the top of the bracket 4 by bolts. When the prisoner tries to use the shielding cover 14 as a climbing point, the weighing sensor 10 will still be triggered. At the same time, the control unit 2 includes a control cabinet 15 and a controller 16 installed in the control cabinet 15, and the control cabinet 15 and the controller 16 are both installed in the guard room. The controller 16 is electrically connected to the motor 9 and the weighing sensor 10. In order to confirm the specific location where the prisoner is trying to escape, the alarm unit 3 includes a control switch 17, a buzzer 18, and a lamp bead 19. The control switch 17 is electrically connected to the controller 16, and the control switch 17, the buzzer 18, and the lamp bead 19 are connected in series in the same circuit. The lamp bead 19 is encoded with a position number, and the position number corresponds to the position of the prison wall. When the electrical signal transmitted by the weighing sensor 10 is transmitted to the controller 16, the controller 16 controls the control switch 17 to be turned on, which is located in the same electrical When the buzzer 18 and the lamp bead 19 in the road are started, the guards can obtain the wall where the prisoner escaped according to the number on the lamp bead 19, and then go out to capture him as soon as possible. The power supply in the circuit in which the control switch 17, the buzzer 18, and the lamp bead 19 are connected in series is AC power. The wall of each prison is divided into several sections, each corresponding to a group, and then the specific escape location can be obtained by simply watching the place where the numbered lamp bead 19 lights up. The present application designs an anti-overcoming roller 5, which can prevent the prisoner from escaping. At the same time, the force generated on the anti-overcoming roller 5 during the escape makes the weighing sensor 10 obtain an electrical signal and transmit it to the controller 16. The controller 16 controls the buzzer 18 and the lamp bead 19 corresponding to the weighing sensor 10 of this section to work, so as to obtain the specific location. It should be noted that the correspondence between the weighing sensor 10 and the corresponding buzzer 18 and the lamp bead 19 is processed by the controller 16. Embodiment 2:

[0024] like Figure 1 , Figure 2 and Figure 4-Figure 6 As shown, in order to prevent the prisoner from escaping by putting the rope around the anti-overlanding roller 5, the surface of the anti-overlanding roller 5 is less than 2 mm away from the wall surface and a first narrowing portion 6 is constructed at the roller body, a first gear 7 is fixed to the first narrowing portion 6, a second gear 8 is meshed outside the first gear 7, a motor 9 is fixedly installed at the axis of the second gear 8, the motor 9 is installed on the wall head and the output shaft end of the motor 9 is fixed at the axis of the second gear 8, the second gear 8 drives the first gear 7 to rotate through the rotation of the motor 9, and then the anti-overlanding roller 5 always rotates outward (i.e. Figure 2At the same time, in order to prevent the prisoners from throwing ropes to hook on other places to cross the anti-rotation rollers 5, multiple groups of anti-rotation rollers 5 are arranged along the height of the fence. The anti-rotation rollers 5 are also constructed with a second narrowing part 11. The second narrowing part 11 is concentrically fixed with a third gear 12. The multiple third gears 12 on the multiple anti-rotation rollers 5 are connected by a chain 13. The chain 13 drives the multiple anti-rotation rollers 5 to rotate. Even if the prisoners climb by pulling the rope, they must step on the flip roller 5. The rolling anti-rotation roller 5 increases the difficulty of climbing. The prisoners must step on the anti-rotation roller 5 to escape, which will inevitably trigger the alarm.

[0025] A security power grid also includes multiple angle irons installed on the wall, with no less than two high-voltage wires pulled between the angle irons, the voltage polarities of the two high-voltage wires are different, and the starting ends of the two high-voltage wires are connected to a transformer connected to the mains, and the tail ends of the two high-voltage wires are connected to a detection transformer, and the detection transformer is electrically connected to a controller 16. It should be noted that the high-voltage wires, transformers, and detection transformers here all adopt the connection and installation method of the existing technology, which adopts reverse polarity voltage output technology and is controlled by the controller 16 to achieve reverse power transmission after short circuit. This technology has been widely used in prison security and will not be elaborated here.

[0026] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
