As shown in fig. 1 and fig. 2, the present embodiment provides a safety alarm device for a safety helmet, which monitors whether a safety risk exists in an operator wearing the safety helmet in real time, and improves the safety of the operator. The safety alarm device specifically comprises an infrared temperature measuring sensor 1, a collision sensor 2, an alarm unit 3 and a processor 4. The infrared temperature measuring sensor 1, the collision sensor 2 and the alarm unit 3 are respectively and electrically connected with the processor 4. The infrared temperature measuring sensor 1 is arranged in the safety helmet and used for detecting the head temperature of a human body and sending the detected temperature to the processor 4; the collision sensor 2 is arranged outside the safety helmet, and the collision sensor 2 is used for detecting whether the safety helmet collides with the outside and the strength of the collision degree; the processor 4 is used for receiving and processing signals of the infrared temperature measuring sensor 1 and the collision sensor 2 and controlling the alarm unit 3 to be turned on or turned off.

The infrared temperature measuring sensor 1 can detect the body temperature of the operator, for example, the body temperature of the neck or the head of the operator, and is specifically installed at the rear edge of the helmet. When the temperature detected by the infrared temperature measurement sensor 1 is within the temperature range of the human body, the processor 4 judges that the safety helmet is worn by the operator; the processor 4 controls the switch 303 of the alarm unit 3 to be opened, and the alarm unit 3 enters a working state. Judging whether the safety helmet collides with the outside or not and the strength of the collision degree according to the numerical value detected by the collision sensor 2; when the safety helmet is collided, the numerical value detected by the collision sensor 2 is sent to the processor 4, the processor 4 judges whether the detected numerical value is larger than the alarm warning value or not, when the detected numerical value is larger than the alarm warning value, the processor 4 judges that the safety risk exists in the operating personnel, and controls the alarm unit 3 to give an alarm; when the detection value is not greater than the alarm warning value, the processor 4 judges that the safety risk of the operator is relatively small, and controls the alarm unit 3 not to give an alarm, so that unnecessary false alarm is avoided, and in addition, if the operator considers that the current situation needs to be rescued, the switch 303 can be manually opened to give an alarm.

The alarm unit 3 comprises an LED alarm lamp 301, a built-in power supply 302 and a switch 303 which are connected in series, and the processor 4 is used for controlling the switch 303 to be in an open state or a closed state. LED alarm lamp 301 is installed the safety helmet outside specifically is cyclic annular parcel in the outer fringe of safety helmet, uses LED alarm lamp 301 can in time remind guardians to have potential safety hazard or accident.

Optionally, the alarm unit 3 further includes an alarm display assembly 304 wirelessly connected to the processor 4, where the alarm display assembly 304 includes a display screen 3041, a storage battery 3042, and a first radio frequency transceiver 3043.

The processor 4 is provided with a second rf transceiver 401, and the first rf transceiver 3043 and the second rf transceiver 401 are used to realize wireless connection. The alarm display component 304 can be made portable, which is convenient for the safety guardian to carry about. The display screen 3041 is connected to the processor 4, and is configured to display information sent by the processor 4. The display information may include a number of the helmet and helmet safety warning information, such as: the display information may be "helmet number: 001; and (4) safety state: and an alarm is given. The safety guardian can remotely monitor whether the safety risk exists in the operator through the alarm display component 304 so as to find the accident in time.

The infrared temperature measuring sensor 1, the collision sensor 2, the alarm unit 3 and the processor 4 form first alarm modules, and each first alarm module is used for detecting one safety helmet. One alarm display assembly 304 is connected with more than two first alarm modules through wireless signals. The safety states of more than two safety helmets can be monitored through one alarm display component 304, and the working efficiency of safety guardians can be improved.

The working principle of the embodiment is as follows: when the worker wears the safety helmet, the infrared temperature measuring sensor 1 detects the body temperature of the human body and sends the body temperature value to the processor 4; after the processor 4 receives the body temperature value of the human body, the safety helmet is judged to be worn by the operator; the processor 4 controls the power-on switch 303 of the alarm unit 3 to be turned on, and the alarm unit 3 enters a working state. Judging whether the safety helmet collides with the outside or not and the strength of the collision degree according to the numerical value detected by the collision sensor 2; when the safety helmet is collided, the numerical value detected by the collision sensor 2 is sent to the processor 4, the processor 4 judges whether the detected numerical value is larger than the alarm warning value or not, when the detected numerical value is larger than the alarm warning value, the processor 4 judges that the safety risk exists in the operating personnel, and controls the alarm unit 3 to give an alarm; when the detection value is lower than the alarm warning value, the alarm unit 3 is not started, so that unnecessary false alarm is avoided, and in addition, if the operator considers that the current situation needs to be rescued, the alarm switch 303 can be manually started to give an alarm.
