In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0039] See also Figure 1 The embodiment of the present invention provides a volume adjustment device, including an acquisition circuit 110 and an adjustment circuit 120. The acquisition circuit 110 is used to acquire the current working state of the working device. The adjustment circuit 120 is electrically connected to the acquisition circuit 110, receives the current working state of the working device, and generates and outputs a first volume adjustment instruction according to the current working state of the working device, wherein the first volume adjustment instruction includes a volume adjustment gain, so that the first audio device adjusts the volume according to the first volume adjustment instruction.

[0040] In this embodiment, the working equipment is arranged in the equipment room, and the first audio equipment is arranged in the operating room. The acquisition circuit 110 is electrically connected to the main control module of the working equipment, and obtains the working state of the working equipment from the main control module of the medical imaging equipment, and then determines the volume adjustment gain included in the first volume adjustment instruction, so that when there is no patient to be scanned, the first audio equipment automatically lowers the volume according to the first volume adjustment instruction to prevent the technician from hearing the machine operation noise, and when there is a patient to be examined, the volume is automatically adjusted so that the technician can clearly hear the patient's call, improve the examination quality and user experience, and also avoid the occurrence of some medical accidents. In addition, it can be understood that the value of the gain can be a positive value or a negative value, and the volume of the first audio equipment increases with the increase of the value of the gain, so the technician can increase or decrease the volume of the first audio equipment by adjusting the value of the gain.

[0041] In one embodiment, there is a preset correspondence between the working state of the working device and the volume adjustment gain. It can be understood that presetting the correspondence between the working state of the working device and the volume adjustment gain can ensure the stability of the volume under the same working state and avoid the sound from fluctuating.

[0042] In one of the embodiments, the working state of the working device includes an idle stage, a preparation stage and a check stage;

[0043] In the idle stage, the volume adjustment gain in the first volume adjustment instruction is 30% of the maximum volume adjustment gain, and the volume of the first audio device after adjustment is 30% of the maximum volume of the first audio device;

[0044] In the preparation stage, the volume adjustment gain in the first volume adjustment instruction is 80% of the maximum volume adjustment gain, and the volume of the first audio device after adjustment is 80% of the maximum volume of the first audio device;

[0045] In the checking stage, the volume adjustment gain in the first volume adjustment instruction is the maximum volume adjustment gain, and the volume of the first audio device after adjustment is the maximum volume of the first audio device.

[0046] In this embodiment, the working status of the working equipment is divided into an idle stage, a preparation stage and an inspection stage, and in the idle stage the volume of the first audio device is set to 30% of the maximum volume of the first audio device, in the preparation stage the volume of the first audio device is set to 80% of the maximum volume of the first audio device, and in the inspection stage the volume of the first audio device is set to the maximum volume. This can automatically reduce the volume of the first audio device when there is no patient to be scanned to prevent the technician from hearing the machine operation noise, and automatically increase the volume of the first audio device when there is a patient to be examined so that the technician can clearly hear the patient's call.

[0047] It is understandable that the gain in the idle stage can be set to a smaller value, or even to 0, and the gains in the preparation stage and the inspection stage can be set to other values. In this embodiment, the gain in the idle stage is set to 30% of the maximum gain of the volume adjustment so that when a loud sound occurs between the equipment, the technician can promptly detect the occurrence of abnormal problems.

[0048] Based on the same inventive concept, the embodiment of the present invention also provides an adaptive intercom system, see Figure 2 The adaptive intercom system includes a volume adjustment device 100, a first audio device 200 and a second audio device 300.

In a specific module design, the volume adjustment device 100 can be directly electrically connected to the second audio device 300, and the second volume adjustment instruction is directly sent to the second audio device 300. The volume adjustment device 100 and the second audio device 300 can also be electrically connected through the first audio device 200, that is, the second volume adjustment instruction is forwarded to the second audio device 300 through the first audio device 200.

[0054] In one embodiment, the volume adjustment device 100 includes an acquisition circuit 110 and an adjustment circuit 120. The acquisition circuit 110 is used to acquire the current working state of the working device. The adjustment circuit 120 is electrically connected to the acquisition circuit 110, receives the current working state of the working device, and generates and outputs a first volume adjustment instruction according to the current working state of the working device, wherein the first volume adjustment instruction includes a volume adjustment gain, so that the first audio device 200 located in the operating room adjusts the volume according to the first volume adjustment instruction. In this embodiment, the acquisition circuit 110 is electrically connected to the main control module of the working device, acquires the working state of the device from the main control module of the medical imaging device, and then determines the volume adjustment gain included in the first volume adjustment instruction, so that when there is no patient scanning, the first audio device 200 automatically reduces the volume according to the first volume adjustment instruction to avoid the technician hearing the machine operation noise, and when there is a patient examination, the volume is automatically adjusted so that the technician can clearly hear the patient's call, improve the examination quality and user experience, and also avoid the occurrence of some medical accidents.

[0055] In one embodiment, there is a preset correspondence between the working state of the working device and the volume adjustment gain. It can be understood that presetting the correspondence between the working state of the working device and the volume adjustment gain can ensure the stability of the volume under the same working state and avoid the sound from fluctuating.

[0056] In one of the embodiments, the working state of the working device includes an idle stage, a preparation stage and a check stage;

[0057] In the idle stage, the volume adjustment gain in the first volume adjustment instruction is 30% of the maximum volume adjustment gain, and the volume of the first audio device 200 after adjustment is 30% of the maximum volume of the first audio device 200;

[0058] In the preparation stage, the volume adjustment gain in the first volume adjustment instruction is 80% of the maximum volume adjustment gain, and the volume of the first audio device 200 after adjustment is 80% of the maximum volume of the first audio device 200;

[0059] In the checking stage, the volume adjustment gain in the first volume adjustment instruction is the maximum volume adjustment gain, and the volume of the first audio device 200 after adjustment is the maximum volume of the first audio device 200.

[0060] In this embodiment, the working status of the working equipment is divided into an idle stage, a preparation stage and an inspection stage, and in the idle stage the volume of the first audio device 200 is 30% of the maximum volume of the first audio device 200, in the preparation stage the volume of the first audio device 200 is 80% of the maximum volume of the first audio device 200, and in the inspection stage the volume of the first audio device 200 is the maximum volume. This can automatically reduce the volume of the first audio device 200 when there is no patient to be scanned to prevent the technician from hearing the machine operation noise, and automatically increase the volume of the first audio device 200 when there is a patient to be examined so that the technician can clearly hear the patient's call.

[0061] It is understandable that the gain in the idle stage can be set to a smaller value, or even to 0, and the gains in the preparation stage and the inspection stage can be set to other values. In this embodiment, the gain in the idle stage is set to 30% of the maximum gain of the volume adjustment so that when a loud sound occurs between the equipment, the technician can promptly detect the occurrence of abnormal problems.

[0062] See also Figure 2 The first audio device 200 includes a first microphone 210 , a first data processing circuit 220 and a first speaker 230 .

[0063] The first microphone 210 is used to collect the voice of the first user and generate first voice information.

[0064] The first data processing circuit 220 is electrically connected to the adjustment circuit 120 and the first microphone 210, respectively, receives the first voice information, performs noise reduction and amplification processing on the first voice information, generates a first audio file according to the first voice information after the noise reduction and amplification processing, and sends it to the second audio device 300, receives the first volume adjustment instruction, generates a volume control signal according to the first volume adjustment instruction, and receives and sends the second audio file.

[0065] The first speaker 230 is electrically connected to the first data processing circuit 220, receives the volume control signal and the second audio file, adjusts the volume according to the volume control signal, and plays the second audio file.

[0066] In this embodiment, the first microphone 210, the first data processing circuit 220 and the operating table are all arranged on the operating table, and the first speaker 230 can be arranged at any reasonable position in the operating room. The first data processing circuit 220 filters the first voice information according to the characteristic frequency of the first microphone 210, increases the signal-to-noise ratio of the first voice information, and amplifies the filtered first voice information to increase the amplitude of the analog waveform of the first voice signal, so as to avoid affecting the communication between the patient and the technician due to the weak first voice information signal.

[0067] In one embodiment, the first audio device 200 further includes a switch circuit 240 electrically connected to the first microphone 210 and the first data processing circuit 220 , respectively, for controlling the connection between the first microphone 210 and the first data processing circuit 220 .

[0068] In this embodiment, in order to prevent the patient from hearing conversations between technicians that they should not hear, generally, the first microphone 210 and the first data processing circuit 220 are disconnected, that is, the switch circuit 240 is disconnected. When the technician needs to talk to the patient, the technician controls the switch circuit 240 to connect the first microphone 210 and the first data processing circuit 220.

[0069] In one embodiment, the second audio device 300 includes a second microphone 310 , a second data processing circuit 320 , and a second speaker 330 .

[0070] The second microphone 310 is used to collect the voice of the second user and generate second voice information.

[0071] The second data processing circuit 320 is electrically connected to the second microphone 310 and the first data processing circuit 220, respectively, and is used to receive the second voice information, perform noise reduction and amplification processing on the second voice information, generate the second audio file according to the second voice information after the noise reduction and amplification processing, and send it to the first audio device 200, and receive and send the first audio file.

[0072] The second speaker 330 is electrically connected to the second data processing circuit 320 and is used to receive and play the first audio file.

[0073] In this embodiment, the second microphone 310 is arranged on the frame of the working equipment, and the second data processing circuit 320 filters the second voice information according to the characteristic frequency of the second microphone 310 and the characteristic frequency of the working equipment, increases the signal-to-noise ratio of the second voice information, and amplifies the filtered second voice information to increase the amplitude of the analog waveform of the second voice signal, thereby avoiding affecting the communication between the patient and the technician due to the weak second voice information signal.

[0074] In addition, the second audio device 300 may include a plurality of second microphones 310, which are distributed at a plurality of positions of the working equipment. For example, one is placed in the aperture of the rack so as to be closest to the patient, one is outside the rack and receives mostly the noise of the working equipment operation, and one is placed at the end of the bed. So that the control system of the working equipment can obtain the input signal level of each microphone and other characteristics of the signal (such as frequency distribution) from the intercom module at the device end, and forward this information to the adaptive volume adjustment device 100. The adaptive adjustment device can more accurately determine the rules of the intercom adaptive control by integrating the working state of the equipment and the input signal level of each microphone. For example, only the microphone input signal level of the equipment operation noise is high, and the input signal level of other microphones is low, indicating that the equipment is truly in an idle state. When the input signal level of the microphone at the end of the bed increases, it is possible that a patient enters the equipment room and starts talking. It is judged that this is the preparation stage. At this time, the output volume of the first speaker 230 can be appropriately increased so that the patient can hear what he says.

[0075] In one embodiment, the first audio device 200 and the second audio device 300 are both provided with a communication serial port and an RF wireless module, and the RF wireless module can directly send and receive data through the communication serial port to achieve data transmission between the first audio device 200 and the second audio device 300.

[0076] In summary, the present invention provides a self-volume adjustment device and an adaptive intercom system. The volume adjustment device includes an acquisition circuit 110 and an adjustment circuit 120. The acquisition circuit 110 is used to acquire the current working state of the working device. The adjustment circuit 120 is electrically connected to the acquisition circuit 110, and is used to receive the current working state of the working device, and generate and output a first volume adjustment instruction according to the current working state of the working device, wherein the first volume adjustment instruction includes a volume adjustment gain, so that the first audio device 200 located in the operating room adjusts the volume according to the first volume adjustment instruction. In the present invention, the adjustment circuit 120 generates a first volume adjustment instruction according to the current working state of the working device, and the first volume adjustment instruction includes a volume adjustment gain, so that the first audio device 200 adjusts the volume according to the first volume adjustment instruction, so that when there is no patient scanning, the volume of the first audio device 200 is automatically reduced to prevent the technician from hearing the machine operation noise, and when there is a patient examination, the volume of the first audio device 200 is automatically increased to enable the technician to clearly hear the patient's call.
