The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further,
As shown in Figure 1, 2, 3, this utility model Shi Wo company produce and the biological function experimental system that appears on the market on the improvement carried out, the present embodiment carries out on BL-420 series of biologic Functional Experiment system-based.Have can identification sensor style interface a biological function experimental system, it comprises microcontroller, analog-digital converter, multiple signals modulate circuit, multiple sensor interface, sensor and USB interface.Wherein USB interface is connected microcontroller with analog-digital converter, and this utility model can adopt data wire to be connected to host computer by this USB interface, can realize the object to this biological function experimental system charging and transfer of data simultaneously.Multiple signals modulate circuit connection mode number converter in this system, described sensor connects multiple sensor interface and multiple sensor interface connection mode number converter.
As shown in Figure 2,3, the type of the sensor comprises Digital ID sensor and impedance mark sensor.Wherein Digital ID sensor comprises sensing unit and microcontroller, and sensing unit is all connected with sensing interface with microcontroller.Impedance mark sensor comprises resistance and sensing unit, and resistance is also all connected sensing interface with sensing unit.During concrete identification, first microcontroller can be attempted with " impedance recognition unit ", sensor being identified.If the sensor identifying identification impedance is less than certain threshold value, so can be according to the impedance information acquisition sensor type of tabling look-up; Otherwise microcontroller will be switched to " digital recognition unit ", by sending after specific " inquiry " instruction to sensor.If after instruction is successful by " Digital ID sensor ", will sensor type information be sent to microcontroller by digital interface, identify successfully, otherwise think that sensor type is unknown.
Improvements of the present utility model are also to comprise sensor recognition unit, and this sensor recognition unit connects respectively microcontroller and multiple sensor interface, and this sensor recognition unit is discriminating digit sign or the sensor of impedance sign simultaneously.The meaning that can simultaneously identify two large class sensors is the microprocessor that at all not can be used for carrying out digital communication in some sensor, if separately add this part will inevitably improve the complexity of sensor, raises the cost.So adopt the method for impedance sign reliable simply again to such sensor.But this impedance sign is because being limited to the problem of impedance precision, cannot identify the sensor type of multiple types, so can improve discernible sensor kind with Digital ID sensor, this recognition unit numeral identification can also adopt UART serial port form of the prior art to identify, and the agreements such as the technology that China Patent No. is 201020179130.3 as adopted or use I2C all can.
In addition this utility model also includes and monitors controller, shaping circuit and stimulator, described monitoring controller connects multiple signals modulate circuit, shaping circuit is connected microcontroller with stimulator, and is also provided with communication isolation module on the circuit between described stimulator and microcontroller.
This utility model is not limited in above embodiment, and the technical scheme that those skilled in the art can draw without creative work according to technique scheme should belong within this utility model says the scope of asking for protection.
