For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the pressure control-based array micro-channel control system of the invention comprises an injection pump 1, a first pipeline 2, a plurality of second pipelines 3 and a controller 4, wherein the injection pump 1 is connected with the input end of the first pipeline 2, the output end of the first pipeline 2 is respectively connected with the input end of each second pipeline 3, and the output end of each second pipeline 3 is connected corresponding to each micro-channel in the array micro-channel structure 5; wherein, the first pipeline 2 is provided with a sensor 21 for monitoring pipeline pressure, and each second pipeline 3 is provided with a control valve 31 for controlling the second pipeline 3 to be switched on or off; pumping a pushing fluid into each micro-channel of the array type micro-channel structure 5 through a first pipeline 2 and a plurality of second pipelines 3 by the injection pump 1; the controller 4 selectively controls the filling pressure of the injection pump 1 and the on-off state of the second pipeline 3 according to the pressure fed back by the sensor 21 and a preset rule to control the flow state of the liquid metal in each micro-channel of the array micro-channel structure 5. Wherein the sensor 21 provided on the first line 2 may be a hydraulic sensor. The pushing fluid is a strong alkaline liquid to adapt to the self-characteristics of the pushed liquid metal. The arrayed micro-channel structure 5, see fig. 2, includes a plurality of micro-channels 51, and the micro-channels 51 are enclosed with liquid metal.
As fluid flows in the tubing in the pressure sensor, the sensor senses the pressure change therein and transmits a signal to the controller 4. The sensor is applicable to various fluids, can be used for pressure measurement of gas and liquid, has a measurement error of less than 0.2% of a measuring range, and has a response time of less than 20ms, and the measurement range is from 340mBar to 7 bar.
Considering the requirements of driving pressure and volume size, an integrated injection pump capable of being controlled accurately is selected, and the highest rated working pressure is 1MPa (air pressure) and 1.2MPa (water pressure); the stroke error is less than or equal to 1%, and the repetition error is 0.3% -0.7%; the linear speed is 0.017-5 mm/s, and the injection precision is controlled to be 0.4154 mu l-2.0833 mu l; the maximum driving force of the piston is more than or equal to 100N; the secondary driving force of the piston is more than or equal to 45N; liquid contact material high borosilicate glass, polytetrafluoroethylene and acid and alkali resistance; the maximum bearing pressure of the liquid path is 0-1 Mpa by reference to positive pressure and 0-0.05 Mpa by reference to negative pressure; the pipeline interface is a 1/4-28UNF internal thread interface; communication interface RS232/RS485/CAN bus.
The control valve 31 can adopt a solenoid valve which can withstand the highest pressure of 2.5bar to supply DC12V in face of the strong alkaline liquid pressure control requirement, wherein a plurality of second pipelines 3 are controlled to be opened and closed by the solenoid valve. The electromagnetic valve is controlled by the controller 4, and can realize single-channel, grouping channel and full-channel switching.
When the hydraulic sensor 21 detects that the pressure of the first pipeline 2 is greater than or equal to a preset threshold value, the controller 4 controls all the second pipelines 3 to be closed and controls the injection pump 1 to stop working. When the hydraulic sensor 21 monitors that the pressure of the first pipeline 2 is greater than or equal to the pressure safety value, injection of pushing fluid into the first pipeline 2 is stopped and all the second pipelines 3 are controlled to be closed, so that the first pipeline 2 and the second pipelines 3 are prevented from being damaged due to overlarge pressure. When the hydraulic sensor 21 detects that the pressure of the first pipeline 2 is smaller than a preset threshold value and the pressure of the first pipeline 2 is larger than or equal to the target pressure of the second pipeline 3, the controller 4 controls the corresponding second pipeline 3 to be closed. When the pressure of the first pipeline 2 is larger than or equal to the target pressure of the second pipeline 3, the pressure of the pushing fluid injected by the second pipeline 3 reaches a preset standard, and the pressure of the second pipeline 3 reaches the preset standard because the target pressure of the second pipeline 3 corresponds to the liquid metal flow state in the micro-channel, the liquid metal flow state in the micro-channel can be regulated to a required position by means of the pushing fluid. And when the hydraulic sensor 21 monitors that the pressure of the first pipeline 2 is smaller than a preset threshold value and the pressure of the first pipeline 2 is smaller than or equal to the target pressure of the second pipeline 3, the corresponding second pipeline 3 is kept open. At this time, it is indicated that the pushing fluid pressure injected from the second pipe 3 has not reached the predetermined standard, and it is necessary to continue the injection of the pushing fluid into the second pipe 3. The pressure of the fluid injected into the second pipeline 3 can be accurately controlled through the electromagnetic valve, so that the flow state of the liquid metal in the micro-flow channel can be accurately controlled.
As shown in fig. 3, the control method of the liquid metal flow state of the array type micro-channel of the present invention uses the control system of the array type micro-channel to control, and the control method comprises the following steps:
step S310: the second pipeline is controlled to be fully opened by controlling the working mode of the control valve;
step S320: controlling the injection pump to work to pump the pushing fluid into the first pipeline;
Step S330: comparing the monitored first pipeline pressure with a preset threshold value;
Step S340: when the monitored pressure of the first pipeline is greater than or equal to a preset threshold value, controlling the second pipeline to be closed completely and controlling the injection pump to stop working;
Step S350: when the monitored first pipeline pressure is smaller than a preset threshold value and the first pipeline pressure is larger than or equal to the target pressure of the second pipeline, the controller controls the corresponding second pipeline to be closed; or when the monitored first pipeline pressure is smaller than a preset threshold value and the first pipeline pressure is smaller than the target pressure of the second pipeline, the corresponding second pipeline is kept to be opened. The target pressure of the second pipeline is preset according to the flow state of the liquid metal in the micro-flow channel.

one or more processors; and
And a storage means for storing one or more programs which, when executed by the one or more processors, cause the one or more processors to implement the control method as described above.
