[0002] With the continuous development of wireless technology, portable photoelectric electromagnetic imaging equipment is increasingly used in medical and scientific research fields. However, in actual use, the instability of wireless transmission, especially when the subject is far away from the photoelectric electromagnetic imaging equipment, is prone to loss of photoelectric electromagnetic data marks, which not only leads to incomplete data, but also may affect subsequent data analysis and processing results, bringing great inconvenience to medical and scientific research work.

[0003] Existing memory products often use a simple retransmission or resending mechanism to deal with data packet loss. However, this mechanism often does not work well in long-distance or offline scenarios. In addition, even with high-performance wireless transmission technology, data packet loss cannot be completely avoided. If data storage is interrupted, the subject may need to cooperate with re-collection, which makes the subject's experience poor. In addition, some subjects, especially those treated with near-infrared devices, are usually patients with brain dysfunction and have low cooperation. These problems limit the performance and user experience of memory in the application of optical and electromagnetic imaging equipment. Utility Model Content

[0026] The present application embodiment provides a data storage device 100 for an optical electromagnetic imaging device. Figure 1As shown, the optical electromagnetic imaging device includes an acquisition device 200 and a terminal 300. The acquisition device 200 is used to continuously acquire the optical electromagnetic data of the subject, and the terminal 300 can be communicatively connected to the acquisition device 200 to obtain the optical electromagnetic data of the subject and display or analyze it.

[0027] Continue to combine Figure 1 , the data storage device 100 is portable, and the data storage device 100 includes a first interface 1, a processing unit 2, a storage module 3 and a second interface 4. The first interface 1 is configured to be removably connected to the acquisition device 200 instead of the terminal 300, and is used to receive the first optical electromagnetic data generated by the acquisition device 200 in real time. The processing unit 2 is electrically connected to the first interface 1 to obtain the first optical electromagnetic data, and processes the first optical electromagnetic data to obtain the second optical electromagnetic data. The storage module 3 is electrically connected to the processing unit 2, and the storage module 3 is used to store the second optical electromagnetic data. The second interface 4 is configured to be removably connected to the terminal 300 instead of the acquisition device 200, so as to transmit the second optical electromagnetic data stored in the storage module 3 thereto.

[0028] Optical electromagnetic imaging equipment can be understood as equipment that can send any one or several signals such as light, electricity, magnetism, etc. to the subject to achieve imaging of the target area, including but not limited to near-infrared equipment, electroencephalographic equipment, and magnetic brain equipment.

[0029] The continuous collection of the acquisition device 200 of the optical electromagnetic imaging device can be understood as a large amount of data collected for a long time, and the data obtained after the collection will be analyzed in an independent terminal 300. Among them, the acquisition device 200 and the terminal 300 can be connected by wire or wirelessly. In some scenarios, such as the terminal 300 and the acquisition device 200 are separated by a long distance, then a wireless connection must be used. The wireless connection may have unstable transmission, resulting in the terminal 300 not receiving the correct data. The storage and transmission of data through the above-mentioned data storage device 100 can ensure that the data collected by the acquisition device 200 is stably transmitted to the terminal 300.

[0030] The interfaces of the acquisition device 200 and the terminal 300 are incompatible, but the first interface 1 is compatible with the interface of the acquisition device 200, and the second interface 4 is compatible with the interface of the terminal 300, so as to ensure stable transmission of data via the interface.

[0031] The above-mentioned data storage device 100 is portable, which can be understood as a storage device that can be carried around, moved and used easily, such as a USB flash drive (U disk), an external hard disk, a mobile hard disk, an SD card, etc., so that users can transfer, store and share data between different devices.

[0032] The above-mentioned first interface 1 and / or second interface 4 can be a communication insert, which is used to be inserted into the socket of the corresponding communication protocol. This application does not specifically limit the socket of the communication protocol corresponding to the first interface 1 and / or second interface 4.

[0033] The removable connection between the first interface 1 and the collection device 200 can be understood as the connection between the first interface 1 and the collection device 200 by plugging and unplugging. When the first interface 1 is plugged into the collection device 200, the first optical and electromagnetic data generated by the collection device 200 can be received in real time through the first interface 1. When the first interface 1 is unplugged from the collection device 200, the first interface 1 cannot receive the first optical and electromagnetic data in real time. The removable connection between the second interface 4 and the terminal 300 can also be understood as a connection by plugging and unplugging.

[0034] The processing method to be executed by the above-mentioned processing unit 2 can be understood as a known data processing method, such as data format processing, data structure conversion, etc. The present application does not specifically limit the processing method to be executed by the processing unit 2, and can enable the second optical and electromagnetic data to be stored via the storage module 3 and read after the terminal 300 receives it.

[0035] Optionally, the processing unit 2 may be a microprocessing unit, such as various single-chip microcomputers. More specifically, the processing unit 2 may be a complex instruction set computing (CISC) microprocessing unit 2, a reduced instruction set computing (RISC) microprocessing unit 2, a very long instruction word (VLIW) microprocessing unit 2, a processing unit 2 running other instruction sets, or a processing unit 2 running a combination of instruction sets. The processing unit 2 may also be one or more dedicated processing devices, such as an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), a digital signal processing unit 2 (DSP), a system on a chip (SoC), and the like.

[0036] In the present application, the first interface 1 of the portable data storage device 100 is removably connected to the collection device 200 rather than the terminal 300, so that the first optical and electromagnetic data generated by the collection device 200 can be received in real time via the first interface 1. The storage module 3 of the data storage device 100 can store the second optical and electromagnetic data obtained based on the first optical and electromagnetic data processing, so that on the basis of receiving a large amount of first optical and electromagnetic data generated by the collection device 200 in real time, large-capacity data storage can be achieved through the storage module 3, thereby ensuring the stability of data storage and the efficiency of data transmission, that is, ensuring the real-time and accuracy of data processing, and effectively avoiding the problem of data packet loss caused by wireless transmission of collected data, and the above-mentioned data storage device 100 has the advantages of convenient operation and easy plugging.

[0037] In some embodiments, the photoelectromagnetic imaging device also includes a near-infrared device, and the data storage device 100 has a first working state and a second working state. In the first working state, the first interface 1 receives first near-infrared data sent by the near-infrared device, and in the second working state, the second interface 4 sends second near-infrared data obtained based on the first near-infrared data to the terminal 300.

[0038] In this way, through the removable connection between the data storage device 100 and the near-infrared device, the first interface 1 can receive the first near-infrared data generated by the near-infrared device in real time, and store the second near-infrared data processed by the processing unit 2 via the storage module 3 of the data storage device 100, thereby achieving the purpose of transmitting the second near-infrared data to the terminal 300.

[0039] It is understandable that, when the photoelectromagnetic imaging device also includes a near-infrared device, the first interface 1 can be configured to be removably connected to the near-infrared device to receive in real time the first near-infrared data generated by the near-infrared device; the processing unit 2 can acquire the first near-infrared data, and process the first near-infrared data to obtain second near-infrared data; the storage module 3 stores the second near-infrared data; the second interface 4 can be configured to be removably connected to the terminal 300 instead of the near-infrared device to transmit the second near-infrared data stored in the storage module 3 to it.

[0040] Optionally, the execution of the first working state and the second working state may be independent or may be executed simultaneously, and this application does not make any specific limitation on this.

[0041] In some embodiments, Figure 2 As shown, the data storage device 100 further includes a power switching module 5 , which is electrically connected to the first interface 1 and the second interface 4 respectively, and receives power via the first interface 1 and / or the second interface 4 .

[0042] In this way, power can be provided to the data storage device 100 through the first interface 1 and / or the second interface 4 by the power switching module 5 , so that the data storage device 100 can work based on the power provided by the power switching module 5 .

[0043] Optionally, the voltage provided by the power switching module 5 to the data storage device 100 may range from 3V to 4V. Preferably, the voltage provided by the power switching module 5 to the data storage device 100 is 3.3V.

[0044] In some embodiments, Figure 2As shown, the data storage device 100 also includes a power supply voltage regulating module 6, the power supply switching module 5 is electrically connected to the second interface 4 through the power supply voltage regulating module 6, the power supply voltage regulating module 6 receives power of a first electrical parameter via the second interface 4, and adjusts the electrical energy of the first electrical parameter to power of a second electrical parameter, and the power supply switching module 5 receives power of the second electrical parameter via the first interface 1.

[0045] In this way, the power received by the second interface 4 can be adjusted by the power voltage regulating module 6, so that the power switching module 5 can supply power to the data storage device 100 based on the power of the adjusted second electrical parameter.

[0046] Optionally, the power supply voltage regulating module 6 may be one of a power supply boost module and a power supply buck module, which is not specifically limited in the present application. When the power supply voltage regulating module 6 is a power supply buck module, the first electrical parameter is greater than the second electrical parameter; when the power supply voltage regulating module 6 is a power supply boost module, the first electrical parameter is less than the second electrical parameter.

[0047] The value range of the first electrical parameter may be 4V to 6V. Preferably, the first electrical parameter is 5V.

[0048] In some embodiments, the data storage device 100 also includes an auxiliary power supply device (not shown in the figure) electrically connected to the power switching module 5. When the power switching module 5 stops supplying power, the auxiliary power supply device provides power to enable the data storage device 100 to operate within a preset time.

[0049] In this way, the power-off protection function of the data storage device 100 can be increased by the auxiliary power supply device, so that after the power switching module 5 loses power, the auxiliary power supply device can keep the data storage device 100 working for a short time.

[0050] Optionally, the auxiliary power supply device may be a large-capacity capacitor, so as to maintain the data storage device 100 to continue to operate or save key data in a short period of time through the large-capacity capacitor. Of course, the auxiliary power supply device being a large-capacity capacitor is only an example, and the auxiliary power supply device may also be a protection circuit or other device capable of auxiliary power supply, which is not specifically limited in this application.

[0051] In some embodiments, when the power switching module 5 supplies power, the auxiliary power supply device uses the power supplied by the power switching module 5 to store electricity.

[0052] In this way, when the power switching module 5 is not powered off and is in a normal power supply working state, the auxiliary power supply device can store power through the power supply of the power switching module 5, so that after the power switching module 5 is powered off, the auxiliary power supply device can promptly provide power for the data storage device 100 to work within a preset time, thereby ensuring data security.

[0053] In some embodiments, Figure 2 As shown, the data storage device 100 further includes a transmission module 7, which is electrically connected to the processing unit 2 and the storage module 3, respectively, and the second optical and electromagnetic data processed by the processing unit 2 is sent to the storage module 3 via the transmission module 7. In this way, the second optical and electromagnetic data processed by the processing unit 2 can be smoothly sent to the storage module 3 via the transmission module 7.

[0054] Optionally, the transmission module 7 may specifically adopt a CH377 control chip to output data to the chip in the storage module 3 .

[0055] In some embodiments, the data storage device 100 further includes a monitoring module (not shown) electrically connected to the power switching module 5, and the monitoring module is used to monitor the working state of the power switching module 5. In this way, the working state of the power switching module 5 can be monitored in real time by the monitoring module, so as to issue a prompt in time when the working state of the power switching module 5 is abnormal.

[0056] It is understandable that the working state of the power switching module 5 at least includes a normal power supply state and an abnormal power supply state. In the normal power supply state, the power switching module 5 can provide stable power with the second electrical parameters to the data storage device 100; in the abnormal power supply state, the power switching module 5 cannot provide stable power with the second electrical parameters to the data storage device 100.

[0057] In some embodiments, the data storage device 100 further includes a card slot and an indicator light (not shown in the figure), the card slot is used to install the storage module 3, and the indicator light displays the storage margin of the storage module 3. In this way, the storage module 3 can be stably installed through the card slot, and the storage margin of the storage module 3 can be timely prompted through the indicator light, so that when the storage margin of the storage module 3 is running low, the first optical electromagnetic data generated by the collection device 200 can be continuously received in real time by replacing the data storage device 100.

[0058] An embodiment of the present application also provides a photoelectric electromagnetic brain functional imaging device, which includes a collection device 200 for collecting photoelectric electromagnetic data. The collection device 200 has a third interface, and the third interface is removably connected to the above-mentioned data storage device 100 for the photoelectric electromagnetic imaging device.

[0059] The optoelectronic and electromagnetic brain functional imaging device using the above-mentioned data storage device 100 is removably connected to the acquisition device 200 rather than the terminal 300 through the first interface 1 of the portable data storage device 100, so that the first optoelectronic and electromagnetic data generated by the acquisition device 200 can be received in real time via the first interface 1. The storage module 3 of the data storage device 100 can store the second optoelectronic and electromagnetic data obtained based on the first optoelectronic and electromagnetic data processing. On the basis of realizing real-time reception of a large amount of first optoelectronic and electromagnetic data generated by the acquisition device 200, large-capacity data storage can also be achieved through the storage module 3, thereby ensuring the stability of data storage and the efficiency of data transmission, that is, ensuring the real-time and accuracy of data processing, and effectively avoiding the problem of data packet loss caused by wireless transmission of acquired data. In addition, the above-mentioned data storage device 100 has the advantages of convenient operation and easy plugging.
