[0032] In one embodiment of the present invention, a vibrator 11 is installed on the cap body 2, and the vibrator 11 is electrically connected to the control module. The vibrator 11 is used to remind people. The detection unit 2 10 uses a pressure sensor, and the pressure sensor is electrically connected to the control module. For example, the vibrator 11 uses a vibration motor, and the vibration motor is installed on the inner side of the top of the cap body 2 or on both sides of the cap body 2. After the vibration motor is started, it brings a certain vibration to the cap body 2, thereby reminding people. The pressure sensor uses a flexible pressure sensor, which is installed at the center of the lining 4. When wearing a helmet, the top of the practical person's head contacts the lining 4, and the pressure sensing line detects whether the safety helmet 1 is worn through pressure changes.

[0033] In one embodiment of the present invention, the control mechanism also includes a control box 12, the control module is installed in the control box 12, and control buttons and a sound and light alarm module are installed on the control box 12, and the control buttons and the sound and light alarm module are electrically connected to the control module respectively.

[0034] In the present invention, the control module can be selected from STM32F103, which has a main frequency of 72MHz, rich peripherals, and can adapt to an ambient temperature of -40 to 85°C. The GPS module can transmit the location information of the safety helmet 1 to the server side, and the back-end terminal monitoring personnel can see the location of the staff at the coal mine site, and can make voice calls with the back-end personnel through the set SIM card. The wireless communication module can use SIM800C, which is a GSM / GPRS module that can realize the transmission of voice, SMS, data and fax information with low power consumption.

[0035] In addition, an RFID positioning module may also be used for personnel positioning. The RFID positioning module includes an RFID tag and an RFID reader, wherein the RFID tag is located on the safety helmet 1 and the RFID readers are distributed in various places of the open-pit coal mine.

[0036] In addition, various sensors can be installed in the control box 12. The sensors are electrically connected to the control module. The sensors can use temperature and humidity sensors, MQ2 to detect gas concentration, MQ7 to detect carbon monoxide concentration and other types of sensors to collect environmental information. When the detected data reaches the set threshold, the staff will be reminded through the sound and light alarm module.

[0037] In one embodiment of the present invention, the voice call units on both sides of the cap body 2 include earphones 13, which are rotatably mounted on both sides of the cap body 2, and are electrically connected to the control module, and a microphone 14 is provided on the earphone body 15. Specifically, the earphone 13 includes an earphone body 15 and a rotating seat 19, and connecting tubes 17 are rotatably mounted on both sides of the earphone body 15, and a connecting rod 16 is inserted in the connecting tube 17, a connecting seat 18 is provided on the cap body 2, and a connecting groove 20 is provided on the rotating seat 19, and the rotating seat 19 is rotatably frictionally connected to the connecting seat 18 through a rotating rod, and the end of the connecting rod 16 away from the connector 24 is rotatably frictionally connected to the rotating seat 19.

[0038] In the present invention, the headset body 15 can cover the ear. Due to the complex working environment and high noise in coal mines, the headset body 15 can be flipped down when making a voice call, and the voice intercom can be carried out through the microphone 14. After use, it can be flipped up again. In addition, when the back-end terminal personnel call, the vibration motor vibrates to remind.

[0039] In one embodiment of the present invention, the plug 1 8 may include a male plug 21, which is electrically connected to the control module through a wire, and the plug 2 9 includes a female plug 22, which is electrically connected to the control module through a wire, and the male plug 21 is plug-connected with the female plug 22. The male plug 21 is provided with an external thread, the female plug 22 is provided with a limit ring 23, and the female plug 22 is provided with a connector 24, one end of the connector 24 is provided with an opening and the interior is hollow, and the other end of the connector 24 is provided with a through hole, and the connector 24 is slidably connected to the female plug 22 through the through hole, and the inner wall of the connector 24 is provided with an internal thread that matches the external thread, and the connector 24 is threadedly connected to the male plug 21.

[0040] In order to improve the comfort of use, a corresponding sponge cover 41 is mounted on the male plug 21 and the female plug 22 , and the sponge cover 41 can slide on the chin strap 1 6 and the chin strap 2 7 .

[0041] In the present invention, the male plug 21 and the female plug 22 act as switches, the power module supplies power to the control module, the male plug 21 and the female plug 22 are electrically connected to the control module through wires, and the control module is powered on and works only when the male plug 21 and the female plug 22 are plugged in and connected. Therefore, when the safety helmet 1 is worn on the head, the pressure sensor does not work at this time, and the wearing method of the safety helmet 1 is incorrect at this time. When the male plug 21 and the female plug 22 are plugged in, the control module works and the pressure sensor starts working. If the pressure sensor does not detect the corresponding head pressure, the situation at this time may be that the person only plugs the male plug 21 and the female plug 22, but does not wear the safety helmet 1 on the head. This situation is still an incorrect wearing method. At this time, the control module controls the vibration motor to work and performs vibration reminders. In order to further improve the reminder effect, a voice player is installed in the control box 12, and the voice player is electrically connected to the control module. When it is not worn correctly, the voice player plays the voice "Please wear the helmet correctly".

[0042] The safety helmet 1 is connected to the back-end management terminal system through the communication module. If the safety helmet 1 is removed in the working area of ​​the coal mine, the back-end terminal system will have a corresponding alarm reminder.

[0043] In one embodiment of the present invention, the import and export management channel 25 includes a base 26, a side plate 27 and a top plate 28, and the base 26, the side plate 27 and the top plate 28 form a frame structure.

An intelligent access control system is arranged inside the main body 33, and a face recognizer 34 is arranged on the import gate 31 and the export gate 32, and the face recognizer 34 is electrically connected to the intelligent access control system. A first gate 35 and a second gate 36 are arranged on the import gate 31. When a person enters, after the infrared receiving module 30 receives the signal from the infrared transmitting module, the control host 29 controls the main body 33 to open the first gate 35. After the face recognizer 34 successfully recognizes the face of the person, the second gate 36 opens, and a third gate 37 is arranged on the export gate 32.

[0046] In the embodiment of the present invention, the infrared transmitting module will only work if the personnel wear the safety helmet 1 in the correct way. Therefore, the personnel need to wear the safety helmet 1 correctly in advance before passing through the access control. After entering the access control management area, the infrared transmitting module transmits a signal and the infrared receiving module 30 receives the signal. At this time, the first gate 35 opens. When the face recognition device 34 successfully recognizes the face of the person, the second gate 36 opens. At this time, the person can pass through the access control, and the GPS positioning module is turned on to locate the position of the person passing through the access control.
