Embodiment 1

[0052] Embodiment 1 of the present invention provides a helmet, which includes, in addition to the helmet body 1 , a rescue module 101 , a central control module 102 and a positioning module 103 arranged on the helmet body 1 . The schematic diagram of the helmet circuit structure is as follows: figure 1 , the overall structure diagram is shown in figure 2 .

[0053] The positioning module 103 is used to receive satellite positioning signals to obtain the position information of the current position;

[0054] A help-seeking module 101, configured to receive a user's help-seeking instruction;

[0055] The central control module 102 is configured to send a distress signal to the preset client 104 according to the distress indication, wherein the distress signal includes the location information obtained from the positioning module 103 .

[0056] When the user is in danger, such as getting lost or falling down and being injured, he can send a help instruction through the help mo...

Embodiment 2

[0062] Embodiment 2 of the present invention provides an embodiment of a safety helmet on the basis of Embodiment 1. The helmet provided in this embodiment has the same structure as the helmet in Embodiment 1, and the positioning module 103 is a satellite positioning module.

[0063] The satellite positioning module can receive GPS or Beidou satellite navigation system satellite positioning signals to obtain current location information.

[0064] The process of the safety helmet provided in this embodiment receiving the distress indication triggered by the user and sending the distress signal to the client 104 is the same as that of the safety helmet provided in Embodiment 1, and will not be repeated here.

[0065] The satellite positioning module obtains the current location information according to the satellite positioning signal, which has the advantage of extremely high accuracy.

Embodiment 3

[0067] Embodiment 3 of the present invention provides an embodiment of a safety helmet on the basis of Embodiment 1. The helmet provided in this embodiment has the same structure as the helmet in Embodiment 1, and the positioning module 103 is a base station positioning module.

[0068] The base station positioning module measures the downlink pilot signals of different base stations, and obtains the TOA (Time of Arrival, time of arrival) or TDOA (Time Difference of Arrival, time difference of arrival) of the downlink pilot signals of different base stations. According to the measurement results and the coordinates of the base stations, Using the trigonometric formula estimation algorithm, the position of the helmet can be calculated.

[0069] The process of the safety helmet provided in this embodiment receiving the distress indication triggered by the user and sending the distress signal to the client 104 is the same as that of the safety helmet provided in Embodiment 1, and...

Abstract

The invention relates to the field of hats, in particular to a safety helmet. The safety helmet comprises a safety helmet body, and a help seeking module, a central control module and a positioning module are arranged on the safety helmet body. The positioning module is used for receiving a satellite positioning signal to obtain position information of a position where a user is located at present. The help seeking module is used for receiving a help seeking indication of the user. The central control module is used for sending a help seeking signal to a preset client side according to the help seeking indication, wherein the help seeking signal contains the position information obtained from the positioning module. Compared with a traditional safety helmet, the safety helmet has the advantage that a positioning function and a help seeking function are additionally set.

Description

technical field [0001] The invention relates to the field of hats, in particular to a safety helmet. Background technique [0002] Safety helmets are protective equipment to prevent impact objects from hurting the head. Existing safety helmet mainly is made up of cap shell, cap liner, lower chin strap and rear hoop. The cap shell is hemispherical, firm, smooth and elastic, and the impact and puncture kinetic energy of the striking object is mainly borne by the cap shell. There is a certain space between the cap shell and the cap liner, which can buffer and disperse the instantaneous impact force, so as to avoid or reduce the direct injury to the head. The chinstrap assists in maintaining the state and position of the hard hat. The back hoop is the locking device for the head hoop. Impact absorption performance, puncture resistance performance, lateral rigidity, electrical insulation and flame retardancy are the basic technical performance requirements for safety helmets....
