[0038] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0039] The utility model embodiment provides a conversion acquisition processing circuit, such as Figures 1 to 3 As shown, including:

[0040] Multiple conversion buttons, each corresponding to a detection scenario. The conversion button can be a button, each corresponding to a detection scenario for a part or a group of parts to be detected. At this time, the corresponding group of excitation electrode patches and collection electrode patches can be placed in a conductive loop by triggering a button, and electric energy can be released and recovered, so that the electric energy can be effectively collected after passing through the human body.

The number of control subcircuits is set in one-to-one correspondence with the number of conversion buttons. The control subcircuit is provided with a control protection resistor R11 in series.

[0042] Multiple excitation subcircuits, each of which includes an excitation power supply Vcc21, excitation response switches QA11, QA1N, and an excitation electrode patch J11, which are connected in series. The excitation response switch is controlled by a primary excitation drive switch. The excitation subcircuit includes an excitation variable resistor RT1, an excitation protection resistor R21, and an excitation indicator light LA11, which are connected in series. The excitation variable resistor, the excitation protection resistor, and the excitation indicator light are connected in series with the excitation drive switch.

[0043] Multiple acquisition sub-circuits, each acquisition sub-circuit includes an acquisition response switch QA21 and an acquisition electrode patch C31 arranged in series, and the acquisition response switch is controlled by the acquisition drive switch.

[0044] The technical solution provided by the utility model, in a possible implementation manner, the acquisition subcircuit includes an acquisition protection resistor R31 and an acquisition indicator light LA21 arranged in series, and the acquisition protection resistor, the acquisition indicator light and the acquisition response switch are arranged in series. The acquisition subcircuit has a corresponding signal output terminal M31. The acquisition drive switch is an optical drive triode.

[0045] The technical solution provided by the utility model is that after the conversion button corresponding to any control subcircuit is triggered, the corresponding control subcircuit is in a pass state, the excitation drive switch and the acquisition drive switch of the control subcircuit will work, and the excitation response switch and the acquisition response switch corresponding to the excitation drive switch and the acquisition drive switch are controlled to be in a pass state, so that the corresponding excitation subcircuit and the acquisition subcircuit are respectively in a pass state. Thus, the purpose of synchronously controlling multiple excitation subcircuits and acquisition subcircuits through one control subcircuit is achieved.

[0046] The technical solution provided by the utility model, in a possible implementation scheme, is as follows Figure 4 As shown, it also includes a main switch Sz, which is connected to all the control sub-circuits respectively, and multiple control sub-circuits are arranged in parallel. The excitation drive switch is an optical drive triode. The purpose of overall control can be achieved through the main switch Sz, that is, when a control sub-circuit needs to be powered on, the corresponding main switch Sz needs to be closed, so that a main switch and multiple key switches can be combined to control the circuit provided by the utility model, and one-key power off can be achieved based on the main switch.

[0047] The technical solution provided by the utility model, in a possible implementation scheme, is as follows Figure 5 As shown, it also includes:

[0048] The first signal comparator and the second signal comparator corresponding to each acquisition subcircuit, the first signal comparator includes a first signal input terminal and a second signal input terminal, and the second signal comparator includes a third signal input terminal and a fourth signal input terminal. The utility model includes a first signal comparator HX1 and a second signal comparator DX1, the first signal input terminal can be the positive input terminal of the first signal comparator HX1, the second signal input terminal can be the negative input terminal of the first signal comparator HX1, the third signal input terminal can be the positive input terminal of the second signal comparator DX1, and the fourth signal input terminal can be the negative input terminal of the second signal comparator DX1. The current output by the signal output terminal M31 can be converted by the boost resistor RX1 to obtain the input voltage signals corresponding to the first signal comparator and the second signal comparator.

[0049] The first signal input terminal and the fourth signal input terminal are connected to the signal output terminal of the excitation subcircuit, the second signal input terminal is used to input a first preset level signal, and the third signal input terminal is used to input a second preset level signal. It should be noted that the first preset level signal and the second preset level signal can be preset by the staff, and the first preset level signal is preferably greater than the second preset level signal.

[0050] When the signal of the excitation subcircuit is greater than the first preset level signal, the first signal comparator outputs a high level signal. Due to the inherent characteristics of the voltage comparator, when its positive input terminal is greater than the reverse input terminal, the corresponding voltage comparator will output a high level signal. In this connection mode, when the signal of the excitation subcircuit is greater than the first preset level signal, it proves that the corresponding electric energy is too large and the human body impedance no longer meets the requirements, so it is necessary to output a high level signal for reminder.

[0051] When the signal of the excitation subcircuit is less than the second preset level signal, the second signal comparator outputs a high level signal. Similarly, due to the inherent characteristics of the voltage comparator, when its positive input terminal is greater than the reverse input terminal, the corresponding voltage comparator will output a high level signal. In this connection mode, when the signal of the excitation subcircuit is less than the second preset level signal, it proves that the corresponding electric energy is too small and the human body electrical impedance does not meet the requirements, so it is necessary to output a high level signal for reminder.

[0052] It also includes a first voltage-dividing resistor R41, R4N and a second voltage-dividing resistor R51, R5N, and the nodes of the first voltage-dividing resistor and the second voltage-dividing resistor are connected to the second signal input terminal respectively. It also includes a third voltage-dividing resistor R61, R6N and a fourth voltage-dividing resistor R71, R7N, and the nodes of the third voltage-dividing resistor and the fourth voltage-dividing resistor are connected to the fourth signal input terminal.

[0053] In a possible implementation of the technical solution provided by the utility model, the output end of the first signal comparator is connected to the first display device LA31, LA3N through the first comparison transistors VE11, VE1N, and the first display device responds to display with the high-level signal. At this time, the first display device will display accordingly, and the staff can understand that the current collected by the corresponding collection patch is high.

[0054] In a possible implementation of the technical solution provided by the utility model, the output end of the second signal comparator is connected to the second display device LA41, LA4N through the second comparison transistor VE21, VE2N, and the second display device responds to display with the high-level signal. At this time, the second display device will display accordingly, and the staff can understand that the current collected by the corresponding collection patch is low.

[0055] Only when the collected current is within the interval between the first preset level signal and the second preset level signal, the first display device and the second display device will not give a reminder.

[0056] The above technical solution enables medical staff to quickly determine the excitation electrode patches and collection electrode patches that need to be powered on when collecting local bioelectricity of the monitored person, and control the corresponding excitation electrode patches and collection electrode patches to power on quickly. In addition, the staff can quickly understand whether the bioelectric energy collected at the corresponding position meets the requirements through the display status of the first display device and the second display device.

[0057] The utility model also provides a cloud-based health risk assessment system, such as Figure 6 As shown, including:

[0058] The analog-to-digital converter is connected to the output end of the first signal comparator and the second signal comparator, and is used to convert the high-level signal into a digital signal. The high-level signal can be converted into a digital signal by the analog-to-digital converter. The 5G communication module is connected to the analog-to-digital converter, and is used to send the digital signal to the cloud server, and the cloud server stores the digital signal in the cloud database. The cloud server displays the digital signal through a display. The cloud server can transmit the digital signal received through the 5G communication module so that the display can display it, so that the staff in the cloud can remotely understand the local bioelectric detection situation, and the corresponding digital signal can be stored through the corresponding cloud database.
