Technical Field
[0001] The utility model relates to the technical field of safety helmets, in particular to a wireless intercom intelligent safety helmet. Background Art
[0002] When inspecting and maintaining high-altitude power transmission lines, there are generally three ways for workers to communicate with each other, namely, shouting, talking on walkie-talkies, and talking on mobile phones. However, in areas with strong winds, high noise environments, and areas without communication signals, the above communication methods have the following disadvantages: (1) Shouting method: When workers are working on a high tower with strong winds or in a noisy working environment, shouting is not only inconvenient, but also ineffective;
[0003] Intercom: Existing intercoms do not have the noise reduction function for sound signals. When using an intercom for communication, the sound signal will not be noise-reduced, resulting in unclear or low-quality intercom sounds.
[0004] Mobile phone calls: Mobile phone calls work in a similar way to walkie-talkies, but they cannot be used in areas with no signal. When working at heights, they are also inconvenient to carry and there is a risk of falling and injuring people.
[0005] Therefore, it is necessary to design and improve the equipment for two workers who are inspecting and maintaining the transmission and distribution lines to talk to each other when inspecting and maintaining the transmission and distribution lines, so as to solve the problem that the workers who are inspecting and maintaining the transmission lines need to carry other communication equipment, which is inconvenient to carry and communicate in places without signals. Utility Model Content
[0006] The purpose of the utility model is to provide a wireless intercom intelligent safety helmet to solve the problem that workers who repair power transmission and distribution lines need to carry other communication devices during the operation and maintenance of power transmission lines, which is inconvenient to carry and difficult to communicate in places without signals.
[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0008] A wireless intercom intelligent helmet comprises a helmet, a loudspeaker and a microphone; the inner wall of the helmet is connected to the outer wall of a support frame, the inner wall of the support frame is connected to the outer wall of a head circumference strap frame, a conversion connector electrically connected to an intercom host is provided on the inner wall of the support frame, the conversion connector is respectively connected to the loudspeaker and the microphone through a transmission line, the microphone is provided at one end close to the helmet visor, and the loudspeaker is provided at one end away from the helmet visor.
[0009] Furthermore, the sound input end of the microphone is located near the mouth of the person wearing the helmet, and the sound output end of the loudspeaker is located near the ear of the person wearing the helmet.
[0010] Furthermore, the single-chip microcomputer chip model built into the intercom host is TMK09-M.
[0011] Furthermore, the transmission line is fastened to the support frame through a rope loop, and the transmission line extends along the support frame to the speaker and the microphone and is connected to the speaker and the microphone respectively.
[0012] Furthermore, the speaker is any one of a small speaker and an elliptical small speaker extender.
[0013] Furthermore, the microphone is a headset microphone.
[0014] Furthermore, the outer wall of the safety helmet is provided with at least three reinforcing ribs.
[0015] During the working process, the worker who is inspecting and maintaining the power transmission and distribution lines first puts on a safety helmet on his head and adjusts the speaker and microphone so that the speaker output end is near the ear of the worker who is inspecting and maintaining the power transmission and distribution lines and the microphone input end is near the mouth of the worker who is inspecting and maintaining the power transmission and distribution lines. Then he ties the intercom host to his body to complete the wearing process of the wireless intercom smart safety helmet. When two workers who are inspecting and maintaining the power transmission and distribution lines on the power transmission and distribution lines want to talk to each other, the two workers first pair the intercoms they are wearing. The words spoken by one of the workers are then received by the microphone on the helmet worn by the worker who is inspecting and maintaining the power transmission and distribution lines. The microphone that receives the sound signal then transmits the sound signal through the transmission line. The sound signal is transmitted to the intercom host attached to the worker who is repairing the power transmission and distribution line. Then, the intercom attached to the worker who is repairing the power transmission and distribution line wirelessly sends the sound signal to the intercom host attached to another worker who is repairing the power transmission and distribution line. The intercom host then transmits the received sound signal to the microphone on the safety helmet worn by the worker who is repairing the power transmission and distribution line. The microphone converts the sound signal into sound to the ear of the worker who is repairing the power transmission and distribution line. In this way, the worker who is repairing the power transmission and distribution line can also talk to another worker who is repairing the power transmission and distribution line in the above manner to realize the intercom process between the two workers who are repairing the power transmission and distribution line, making the intercom between the two workers who are repairing the power transmission and distribution line more convenient.
[0016] Compared with the prior art, the present invention has at least one of the following beneficial effects:
[0017] The utility model combines a safety helmet, a loudspeaker, a microphone and an intercom host into a wireless intercom intelligent safety helmet. When workers inspecting and maintaining power transmission and distribution lines are working at height or in areas without communication equipment or mobile phone signals, two workers inspecting and maintaining power transmission and distribution lines only need to wear the wireless intercom intelligent safety helmets to communicate with each other. There is no need to wear additional communication equipment, which will cause no burden to carry, and the effect of smooth communication can be achieved, thereby improving the safety and efficiency of operations. This solves the problem that workers inspecting and maintaining power transmission and distribution lines need to carry other communication equipment, which is inconvenient to carry, and have difficulty communicating in areas without signals.
[0018] 2. The built-in chip model of the walkie-talkie in the present invention is TMK09-M, which has ANC noise reduction and ENC noise reduction functions. Therefore, the walkie-talkie with the built-in TMK09-M chip is used in the scene of two-person intercom during the process of power transmission and distribution line maintenance by workers, which indirectly improves the call quality between the workers who are repairing the power transmission and distribution lines, and solves the problem that the existing walkie-talkies do not have the noise reduction function of the sound signal. When the walkie-talkies are used for intercom, the sound signal will not be noise-reduced, resulting in unclear intercom sound or low intercom quality.
[0019] 3. The built-in chip model of the intercom in this utility model is TMK09-M. This chip has call priority (a channel is reserved for designated personnel to have the right to talk at any time to protect the leadership rights). When the operation control personnel is talking to two workers who are repairing the transmission and distribution lines, the operation control personnel will have priority to talk to the two workers who are repairing the transmission and distribution lines, so as to control the safety of the operation and correct errors that occur during the operation in time, thereby improving the safety and efficiency of the operation.
[0020] 4. This utility model is a wireless intercom smart helmet composed of a helmet, a speaker, a microphone and an intercom host. There is no need to pay for communication fees, only the equipment itself needs to be purchased. The full-duplex intercom safety helmet can help enterprises or individuals save a lot of communication costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1-4 In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example
[0027] When inspecting and maintaining high-altitude power transmission lines, there are generally three ways of communication between two workers inspecting the transmission and distribution lines. The three communication methods are shouting, talking on walkie-talkies, and talking on mobile phones. The above communication methods have the following disadvantages: inconvenient communication and low communication quality.
[0028] Therefore, the present application proposes a wireless intercom smart helmet to solve the problem that workers who repair power transmission and distribution lines need to carry other communication devices during operation and maintenance of power transmission lines, which is inconvenient to carry and communicate in places without signals.
[0029] See also Figure 1 、 Figure 2 and Figure 3 A wireless intercom intelligent helmet includes a helmet 1, a speaker 2 and a microphone 3; the inner wall of the helmet 1 is connected to the outer wall of the support frame 4, the inner wall of the support frame 4 is connected to the outer wall of the head circumference strap frame 5, and a conversion connector 7 electrically connected to the intercom host 6 is provided on the inner wall of the support frame 4. The conversion connector 7 is connected to the speaker 2 and the microphone 3 through a transmission line 8 respectively. The microphone 3 is arranged at one end close to the helmet visor 8, and the speaker 2 is arranged at the end away from the helmet visor 8.
[0030] In actual use, the worker who inspects the transmission and distribution lines first wears a safety helmet on his head, and adjusts the speaker 2 and the microphone 3 so that the sound output end of the speaker 2 is near the ear of the worker who inspects the transmission and distribution lines and the sound input end of the microphone 3 is near the mouth of the worker who inspects the transmission and distribution lines, and then ties the intercom host 6 on his body to complete the wearing process of the wireless intercom smart safety helmet; when two workers who inspect the transmission and distribution lines on the transmission and distribution lines want to talk to each other, the two workers who inspect the transmission and distribution lines first pair the intercom hosts 6 worn by each of them, and the words spoken by one of the workers who inspect the transmission and distribution lines are received by the microphone 3 on the safety helmet 1 worn by the worker who inspects the transmission and distribution lines, and the microphone 3 that receives the sound signal then transmits the sound signal through the transmission line 8 The signal is transmitted to the intercom host 6 attached to the worker who is repairing the transmission and distribution lines. Then, the intercom host 6 attached to the worker who is repairing the transmission and distribution lines wirelessly sends the sound signal to the intercom host 6 attached to another worker who is repairing the transmission and distribution lines. The intercom host 6 then transmits the received sound signal to the microphone 3 on the safety helmet 1 worn by the worker who is repairing the transmission and distribution lines. The microphone 3 converts the sound signal into sound to the ear of the worker who is repairing the transmission and distribution lines. In this way, the worker who is repairing the transmission and distribution lines can also talk to another worker who is repairing the transmission and distribution lines in the above manner to realize the intercom process between the two workers who are repairing the transmission and distribution lines, making the intercom process between the two workers who are repairing the transmission and distribution lines more convenient.
[0031] In order to improve the quality of communication between transmission and distribution line workers, the sound input end of the microphone 3 is located near the mouth of the person wearing the helmet, and the sound output end of the loudspeaker 2 is located near the ear of the person wearing the helmet.
[0032] In actual use, when a power transmission and distribution worker wearing a safety helmet talks with other power transmission and distribution workers, since the sound input end of microphone 3 is located near the mouth of the person wearing the safety helmet, microphone 3 can clearly and accurately receive the voice of the power transmission and distribution worker; in addition, since the sound output end of loudspeaker 2 is located near the ear of the person wearing the safety helmet, the power transmission and distribution worker can hear the voices of other power transmission and distribution workers clearly, indirectly improving the quality of communication between the power transmission and distribution workers.
[0033] Among them, in order to improve the quality of intercom and reduce intercom noise, the built-in single-chip microcomputer chip of the intercom host 6 adopts the model TMK09-M chip. The TMK09-M chip has ANC (active noise reduction (ANC): the microphone in the headset collects external environmental noise, and then the system generates sound waves with opposite phase to the noise to offset it) and ENC noise reduction technology (environmental noise reduction (ENC) uses multiple microphone arrays to model environmental noise, accurately calculate and block noise, so that the other party can hear the voice clearly in a noisy environment), echo cancellation technology, push-to-talk and VOX intercom dual modes, support DPWM and I2S (Inter-IC Sound is a serial interface standard widely used in digital audio transmission. The chip was originally developed by Philips to solve the problem of transmitting audio data between integrated circuits) interfaces, point-to-group calling (you can specify to call a certain person or a group call), and set call priority (reserving a channel for designated personnel to have the right to talk at any time to protect leadership rights).
[0034] In actual use, since the TMK09-M chip has ANC and ENC noise reduction technologies and call priority (reserving a channel for designated personnel to have the right to talk at any time to protect leadership rights) functions, the walkie-talkie with a built-in TMK09-M chip is used in the scenario of two-person intercom during the process of power transmission and distribution line maintenance by workers. This not only improves the call quality between the workers, but also allows the management personnel to give priority to talking to the two workers when the maintenance team leader is talking to them, so as to convey maintenance precautions during the maintenance process.
[0035] It should be noted that the above supports the highest priority intercom, that is, when the channel is full, the intercom with the highest authority can still join the intercom, ensuring that orders and commands can be issued in a timely manner, improving timeliness and safety.
[0036] In order to prevent the transmission line 8 from getting tangled inside the helmet, the transmission line 8 is tied to the support frame 4 through a rope loop. The transmission line 8 extends along the support frame 4 to the speaker 2 and the microphone 3 and is connected to the speaker 2 and the microphone 3 respectively.
[0037] In actual use, when the power transmission and distribution workers wear the safety helmet, since the transmission line 8 is tied to the support frame 4 through the rope loop, the transmission line 8 will not be entangled with the head circumference strap frame 5 inside the safety helmet, so that the power transmission and distribution workers can wear the helmet smoothly.
[0038] It should be noted that, in order to improve the clarity of the sound, the speaker 2 for playing the sound is preferably any one of a small speaker and an elliptical small speaker extender. Other types of speakers can also be selected according to actual working conditions.
[0039] It should be noted that, in order to reduce the overall weight of the microphone 3 , the microphone 3 used for receiving the voice of the power transmission and distribution line worker is a microphone headset.
[0040] Among them, in order to improve the overall strength of the safety helmet 1, at least three reinforcing ribs are provided on the outer wall of the safety helmet 1. The three reinforcing ribs are arc-shaped strip structures. Reinforcing ribs of other shapes can also be selected in due course according to actual conditions.
[0041] In actual use, when a foreign object falls and hits the safety helmet, the three reinforcement ribs are provided on the outer wall of the safety helmet 1, and the three reinforcement ribs are hit first. After the three reinforcement ribs impact and buffer, the impact on the safety helmet is weakened, which indirectly improves the overall strength of the safety helmet.
[0042] This application combines a safety helmet, a speaker, a microphone and an intercom host into a wireless intercom smart safety helmet. When workers inspecting and maintaining power transmission and distribution lines are working at heights or in areas without communication equipment or mobile phone signals, they can communicate with each other through the wireless intercom smart safety helmets they wear. There is no need to wear additional communication equipment, and smooth communication can be achieved, thereby improving work safety and efficiency.
[0043] Although the present invention has been described herein with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and implementations may be devised by those skilled in the art that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the present disclosure, the drawings, and the claims, various variations and modifications may be made to the components and / or layout of the subject combination arrangement. In addition to variations and modifications to the components and / or layout, other uses will also be apparent to those skilled in the art.
