Preferably, one end of the connecting rod 2 is hingedly connected with the fixed rod 1, the connecting rod 2 can freely rotate along the hinge shaft, and the two ends of the connecting rod 2 are arc-shaped (not shown in the figure) to ensure free rotation;
[0047] A cross rod 3 is movably connected with the other end of each connecting rod 2. Preferably, the other end of the connecting rod 2 is hingedly connected with the cross rod 3;
[0048] An infrared distance sensor 4 is arranged at the end of one end of the cross rod 3. The sensing head of the sensor is in the same direction as the cross rod 3, which is described as Figure 1When the guardrail is in the raised state, there will be a gap at both ends, and the patient can get off the bed from the gap without putting down the guardrail. By setting the infrared distance sensor, the distance between the sensor and the object can be detected to detect whether the gap has an object passing through. By setting the infrared distance sensor 4 on the crossbar 3, the patient's clothes, quilt and other objects can be avoided to be blocked to cause false triggering. The infrared distance sensor belongs to a mature technology, and a commercially available product can be used to realize it. In this embodiment, a gy56 infrared laser distance sensor is used to realize it.
[0049] The baffle 5 is connected with the fixed rod 1, and the infrared distance sensor 4 is arranged at the end of one end of the crossbar 3. When the connecting rod 2 and the crossbar 3 are in the Figure 2 lowered state as shown in the figure, the infrared distance sensor 4 faces the baffle 5. By setting the baffle 5, when the guardrail is lowered, the distance between the sensor and the object will also change, thereby realizing the joint monitoring of the lowering of the guardrail and the passing of the object in the gap.
[0050] Preferably, the guardrail further comprises a locking mechanism, as shown in Figure 5 , the left and right are schematic diagrams in the locked state and the unlocked state respectively, which specifically comprises:
[0051] The pressing block 6 is movably connected with the crossbar 3;

[0053] The first connecting block 9 is fixedly connected with the crossbar 3;
[0054] The second connecting block 10 is fixedly connected with the connecting rod 2. Referring to Figure 1 , when the guardrail is in the raised state, the first connecting block 9 matches with the second connecting block 10;
[0055] The lock shaft 11 is connected with the movable plate 7, and in the locked state, the lock shaft 11 penetrates through the first connecting block 9 and matches with the groove on the second connecting block 10. By pressing the pressing block 6, the lock shaft 11 can be lifted to unlock the first connecting block 9 and the second connecting block 10.
[0056] Preferably, the fixed rod 1 is provided with an opening 12 matched with the first connecting block 9 and the second connecting block 10, as shown in Figure 2 , when the guardrail is in the lowered state, the first connecting block 9 and the second connecting block 10 fall into the opening 12. In addition, a plurality of connecting rods 2 are the same size and are arranged at equal intervals, and the length of the connecting rod 2 is less than the interval between the adjacent two connecting rods 2. The plurality of connecting rods 2 are arranged in parallel, the crossbar 3 is arranged in parallel with the fixed rod 1, and the connecting rod 2 is arranged vertically with the fixed rod 1.
[0057] Preferably, it further comprises:
[0058] The side plates 13 are connected with the fixed rods 1 and are arranged on opposite sides of the connecting rods 2 and are connected with the hinge shafts.
[0059] Preferably, the infrared distance sensor 4 is connected to the main control chip (not shown in the figure) connected to the fixed rod through the connecting line arranged in the rod, and the main control chip is connected with alarm elements such as warning lights and loudspeakers. The main control chip is configured to issue an alarm when bed exit is monitored, and then the nurse can timely go to give help to prevent the occurrence of patient falling accidents.
[0060] In the embodiment, the main control chip can adopt the MCU control module, PLC industrial control module and the like which have been widely used in the prior art, or other control modules capable of realizing control functions and suitable for the control of the embodiment can be purchased and applied. In the embodiment, the main control chip can be realized by using an STM32 series chip.
[0061] It should be noted that the connection mode between the main control chip and the infrared distance sensor 4 and the alarm elements, and the built-in software of the main control chip are realized by using the prior art.
[0062] Preferably, the outer surface edges of each component of the guardrail of the embodiment are subjected to smoothing treatment to avoid accidental injury caused by sharp edges.
[0063] The working principle of the guardrail is as follows: when the guardrail is raised to the raised state shown in Figure 1 , the first connecting block 9 matches the second connecting block 10, the lock shaft 11 penetrates into the groove on the second connecting block 10, and the overall limiting of the guardrail is realized. The infrared distance sensor 4 monitors the distance from the barrier, and when the patient gets out of bed from the gap at the end of the guardrail or lowers the guardrail, the distance detected by the sensor will change, thereby realizing the monitoring of bed exit. When the guardrail is lowered, the pressing block 6 is pressed, the movable plate 7 and the lock shaft 11 are lifted, the lock shaft 11 is separated from the groove on the second connecting block 10, and the locking mechanism is converted from the locked state to the unlocked state. The guardrail is pulled to the lowered state shown in Figure 2 by pulling the cross rod 3.
