When the refrigerating and heating is out of line, the system has self-checking function.
The manual operation module 5 is electrically connected to the drive module 3 and the control module 1 for manually adjusting configuration parameters in the drive module 3, including type selection parameters of the sensor and accuracy adjustment parameters of the sensor. The accuracy of the different sensors is different, and the adjustment mode is also different.
In addition, besides the requirement of the ambient temperature inside the bioreactor, a certain requirement of the ambient temperature is also required outside the bioreactor, so that the sampling module 4 is additionally provided with an ambient temperature sensor, and the ambient temperature sensor is electrically connected to the control module 1. The control module 1 receives temperature feedback information of the environmental temperature sensor, so that workers can check environmental factors conveniently, influence of the environmental factors on the bioreactor is reduced, and the control accuracy of the control module 1 is improved.
In order to achieve that manual control is also possible, the manual operation module 5 of the present application comprises a plurality of electric field plates, which may be circular or square plates, with different functions.

One end of the wire 54 is annular or spiral, and the axial direction of the annular or spiral is perpendicular to the electric field plate; the other end is straight and extends out of the shaking gap 53 and forms the touch end 7. The driving plate 31 is also provided with a micro switch, the micro switch is electrically connected to the driving module 3, one linear end of the metal wire 54 is electrically connected to a positive power source electrode a, a negative power source electrode b is electrically connected to a fixed end 56 of the micro switch, and a movable end 55 of the micro switch is fixedly and electrically connected to one linear end of the metal wire 54. The movable end 55 of the micro switch is hinged on the driving plate 31, and the movable end 55 is positioned at one side of the fixed end 56 away from the driving plate 31.
Referring to fig. 3, when no operator touches the touch end 7, since there is an electric field between the positive plate 51 and the negative plate 52 and the wire 54 is positively charged and the weight of the wire 54 is equal to that of the positive plate 51, the wire 54 is close to the positive plate 51, so that the annular part of the wire 54 is deflected near the negative plate 52 according to stress analysis, and in an ideal state, one end of the annular wire 54 floats in the middle position of the two, and the micro switch is in an open state, i.e. no trigger signal. Referring to fig. 4, when an operator touches the touch terminal 7, the positive charge on the annular wire 54 is led to the ground due to the grounding effect of the manual touch, so that the annular wire 54 generates instantaneous current, and according to ampere's rule, the wire 54 can have an electric field force for moving the wire 54 close to the positive plate 51, so that the micro switch is closed; referring to fig. 5, when closed and the hand leaves the touch end 7, positive charge is recovered on the looped wire 54 and the instantaneous magnetic field at this time is opposite to the former, thus generating a force that moves the wire 54 towards the negative plate and accelerating the opening of the microswitch; in summary, when the electric charges on the annular metal wire 54 flow, a magnetic field can be generated, and the generated magnetic force can adsorb surrounding magnetic conductive metals, such as the positive plate 51; therefore, when the touch end 7 is touched, the electric attraction or the electric repulsion which is not influenced by an electric field can be caused by the loss of electric charges, and the magnetic field generated by the loss of the electric charges can absorb the nearest iron electric field polar plate.

The fixed connection between the movable end 55 of the micro-switch and the metal wire 54 is sleeved with an anti-shake elastic conductive film 59. Because the wire 54 has a certain length relative to the micro-switch, and the wire 54 also needs to float in the electric field E against its own gravity, there is a possibility that the wire 54 will swing left and right, and the anti-shake elastic conductive film 59 can increase the connection stability at the connection point between the wire and the micro-switch, and reduce the micro-switch action caused by shake, thereby being beneficial to more accurate configuration parameters.
Further, the influence of an external electric field on the electric field between the positive electrode plate 51 and the negative electrode plate 52 is reduced, and a shield case 58 is provided over the electric field plate.
In order to visualize the operating electric field plate, the positive plate 51 is provided as a light-transmitting plate, and the power negative electrode b and the fixed end 56 of the micro switch are electrically connected to a prompting circuit for receiving and responding to a prompting signal of closing the micro switch.

Wherein the LED lamp is hidden at the side of the negative electrode plate 52 away from the positive electrode plate 51. The hidden arrangement is beneficial to protecting components and parts and prolonging the service life. The LED lamp in the prompt circuit is used for realizing the action visualization of the touch operation metal wire, so that the verification function is realized.
In order to further ensure the stability of the micro-switch triggering, the micro-switch is not easy to be interfered by the outside, and a buffer layer 6 is arranged between the negative plate 52 of the electric field plate and the driving plate 31. The buffer layer 6 has a certain buffering and damping effect, and reduces the influence of vibration of the driving plate 31 on the electric field plate.
Referring to fig. 6, the wire 54 is wound in a spiral shape and is wound in a spiral shape, and then is bent into a hook-shaped ring, so that the structure can increase the stress part or stress length in the electric field, increase the acting force of the electric field, and generate the magnetic field acting force indicated by the circular arrow in the figure, the magnitude of the magnetic field acting force is far greater than that of the magnetic field force generated by the common circular wire 54 in fig. 2, and simultaneously, the magnetic field acting force and the hook-shaped end of the ring generate torsion force, so that the ring is deformed and then leans against the electric field to drive the rotating rod, and the spiral ring has elasticity, so that the magnetic force acts more gently.
