In order to make the purpose, technical solutions and advantages of the embodiments of the invention clearer, the technical solutions 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. Obviously, the described embodiments are Some, but not all, embodiments of the invention. The components of the embodiments of the invention generally described and illustrated in the figures herein may be arranged and designed in a variety of different configurations. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
 This embodiment provides an electronic handcuff with an alarm function, which is characterized in that: it includes a handcuff body and a core module; the handcuff body includes a fixed ring, a movable ring, and a bayonet pin; the core module includes a collision sensor , pulse sensor, pressure sensor, high-voltage generating module, high-voltage electric shock sheet, microcontroller unit, micro-drive unit, battery, wireless charging module, speaker, display, wireless communication module, sound and light alarm module; the pressure sensor is configured in On the inside of the fixed handcuff ring, the pressure sensor is connected to the microcontroller to detect the pressure on the fixed handcuff ring and the wrist; the microcontroller control signal output terminal is connected to the speaker, and the microcontroller is connected to the high-voltage electric shock sheet through the high-voltage generator; The bayonet is located on the fixed ring and is used to fix the movable ring on the fixed ring; the wireless communication module is connected to the microcontroller for data transmission with other terminal devices; the sound and light alarm module is connected to the The output terminals of the microcontroller are connected, including an audio amplifier circuit and an LED flashing circuit connected to LED lights of different colors, which are respectively used for collision alarm, over-pulse alarm and over-pressure alarm.
 Preferably, the micro-driver module includes a first micro-driver and a second micro-driver; the first micro-driver is connected to the movable shackle ring for adjusting the position of the movable shackle ring; the second micro-driver is connected to the detent, Used to adjust the position of the detent.
 Preferably, when the data detected by the collision sensor exceeds the collision setting threshold, or the pulse data detected by the pulse sensor reaches the pulse setting threshold, the controller drives the active handcuffs to contract through the first micro-driver, and the pulse data detected by the pulse sensor When the normal value is reached, the controller drives the bayonet through the second micro-driver to fix the electronic handcuffs, and realizes an alarm through the light-emitting alarm module.
 Preferably, when the pressure data measured by the pressure sensor is less than the set threshold, or the pulse data detected by the pulse sensor reaches the pulse set threshold, the controller outputs a valid signal to the high pressure generating module.
 Preferably, the electronic handcuffs also include a Beidou positioning module and a GPS positioning module, which are arranged in the case and connected to the input terminal of the microprocessor.
 When the criminal uses violent actions, when the collision sensor detects that the acceleration data is too high, an alarm will be issued, and the microcontroller unit controls the high-voltage generating module to shock the criminal through the high-voltage electric shock sheet.
