[0028] Working principle: The mechanical lock body 2, the limit lock head 3 and the electronic lock 4 are all installed on the transfer rod 12 of the guardrail body 1 according to the use requirements. Then the entire guardrail is fixed on the bed. When the guardrail needs to be pulled up, the top rod 11 can be directly lifted. After the top rod 11 is lifted, the limit rod 32 is pulled so that the limit rod 32 is disengaged from the second card slot 126, and then the mechanical lock body 2 is pressed down so that the limit lock rod 24 of the mechanical lock body 2 is inserted into the limit lock slot 132, and the limit rod 32 is inserted into the first card slot 125. At this time, all the transfer rods 12 cannot rotate, and the entire guardrail is stable. After that, the electronic lock 4 is controlled so that the lock tongue 44 extends out, and the extended lock tongue 44 is inserted into the limit slot 323, so that the limit rod 32 cannot be pulled. At this time, it can be ensured that the guardrail body 1 will not be easily unlocked. When the guardrail needs to be retracted, a password or fingerprint must be input into the electronic lock 4 so that the lock tongue 44 retracts into the electronic lock 4. At this time, the limit rod 32 can be pulled to disengage the limit rod 32 from the first slot 125, and the mechanical lock body 2 is moved upward at the same time so that the limit lock rod 24 disengages from the limit lock slot 132. At this time, the top rod 11 can be pressed downward to retract the guardrail body 1. Compared with the prior art, the present application installs a limit lock head 3 on the mechanical lock body 2, and the mechanical lock body 2 can be fixed by the limit lock head 3 to achieve the purpose of limiting the position of the bed guardrail and ensure the stability of the bed guardrail. The mechanical lock body 2 is installed with an electronic lock 4, and the limit lock head 3 can be fixed by the electronic lock 4.

[0035] like Fig. 9As shown, it also includes a wireless alarm system, which is connected to the central control module of the electronic lock 4. The wireless alarm system integrates a data processing module, and the data processing module is connected to an abnormal vibration sensor, an abnormal input sensing module, a low power sensor, a signal processing module, a wireless signal transmission module and an acoustic and visual alarm. The data processing module is used to centrally process and integrate the data sensed by the wireless alarm system. The abnormal vibration sensor is used to feedback a signal to the wireless alarm system to issue an alarm when it senses abnormal vibration in the electronic lock 4. The abnormal input sensing module is used to feedback a signal to the wireless alarm system to issue an alarm when an error occurs in entering a password or fingerprint for multiple consecutive times. The low power sensor is convenient for feedback of a signal to the wireless alarm system to issue an alarm when the electronic lock 4 is low on power. The signal processing module is convenient for processing the generated alarm signal, and the wireless signal transmission module is used to remotely transmit the alarm information to the terminal; the acoustic and visual alarm is used to issue an acoustic and visual alarm. The distance of the signal transmission between the wireless signal transmission module and the terminal is calculated by the following formula: ;in Indicates the transmission distance. is the speed of light, is the operating frequency, is the inductor, is capacitance; this formula is used to estimate the approximate distance that a signal can be transmitted under specific frequency, inductance, and capacitance conditions, which helps to rationally plan the layout of the wireless alarm system and ensure that the signal coverage range meets the requirements. The attenuation of the signal strength when the wireless signal transmission module transmits the wireless signal is calculated by the following formula: ,in is the distance from the emission source The signal strength at is the signal strength at the transmitting source, is the path loss exponent, It is the reference distance. This description of the signal intensity attenuation as the distance increases during transmission is of great significance for determining the distance at which the receiver can effectively receive the signal and evaluating the impact of different environments on signal attenuation. It can help optimize the settings of the transmitter and receiver in the system to ensure that the alarm signal can be stably received under various conditions.
