Description
Technical field
This utility model belongs to bio signal collection and processing system field, is specifically related to a kind of bio signal collection and processing system of the USB of employing power supply.
Background technology
The bio signal acquisition system is that research worker, academics and students can be through this systematic observation in various living organisms or the waveform of biological non-electrical signals such as the bioelectrical signals that detects in the isolated organ and tension force, pressure, temperature, thereby the function that biological human body is taken place under different physiology or pharmacological evaluation condition is changed the equipment that write down with analysis.The biological function experimental system is one of capital equipment and means of the biological functional activity of research.Usually, bio signal collection and processing system all are continuous operations, and operating frequency is high, and also comprising stimulates output, so power consumption is bigger, usually adopts the 220V Alternating Current Power Supply.But, because working condition is limit, can't carry out Alternating Current Power Supply sometimes, cause thing signals collecting and the processing system can't operate as normal.Therefore need improve the power supply mode of prior biological signals collecting and processing system.
The utility model content
The purpose of this utility model is to overcome the deficiency of existing bio signal collection and the existence of processing system power supply mode, and a kind of bio signal collection and processing system of the USB of employing power supply is provided.
The technical scheme that this utility model is adopted to achieve these goals is following: a kind of bio signal collection and processing system of USB power supply; It comprises signal input interface, signal output interface, microcontroller, A/D converter, multiple signals modulate circuit and power module; Said signal input interface is connected with the multiple signals modulate circuit; The multiple signals modulate circuit connects A/D converter and connects, and A/D converter and signal output interface are all connected with microcontroller, it is characterized in that also comprising that one is used to supply power and the usb data line of transfer of data; This usb data line one end connects microcontroller, and the other end connects computer.
The technical scheme that is more preferably in this utility model is: signal input interface comprises the bio signal input interface and triggers input interface; And also be provided with analog switch between signal input interface and the multiple signals modulate circuit, signal output interface comprises monitors output interface and stimulator output interface.
This utility model adopts computer USB to supply power to bio signal collection and processing system, does not need extra external power supply, has guaranteed that whole system can continue operate as normal; Thereby greatly facilitate user; Reduced and used constraint, replaced original power source special, therefore simplified equipment with the power supply of usb data line; Reduce cost, had stronger practicality.
Description of drawings
Fig. 1 is this utility model structured flowchart.
The specific embodiment
Further specify below in conjunction with the technical scheme of accompanying drawing, but this utility model is not limited in following embodiment this utility model.
As shown in Figure 1; A kind of bio signal collection and processing system of USB power supply comprise signal input interface, signal output interface, microcontroller, A/D converter, multiple signals modulate circuit and power module; Wherein signal input interface is connected with the multiple signals modulate circuit after connecting analog switch, and signal input interface has comprised the biological various signal input interfaces of needs observation such as bio signal input interface, triggering input interface generally speaking.Described signal output interface comprises monitors output interface and stimulator output interface etc.The multiple signals modulate circuit connects A/D converter and connects, and A/D converter and signal output interface are all connected with microcontroller.The improvement of this utility model just be a power module to be set in this internal system, connecing a usb data line that is used to supply power with transfer of data then, this usb data line one end connects microcontroller, the other end connects computer.
