Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of a fluid delivery control device according to the present invention.

In a first embodiment, a fluid delivery control device includes: a flow pump 100 and a drive module 200; the flow pump 100 is connected to the drive module 200.

It can be understood that the flow pump 100 is used as a power element to drive the fluid to flow in the preset pipeline, and the output end of the driving module 200 is connected with the motor of the flow pump 100 to control the rotation speed of the motor, so as to drive the flow pump to rotate. Specifically, the flow pump 100 may be a peristaltic pump, but may also be other pumps, and the present embodiment is not limited thereto.

The input end of the flow pump 100 is connected to a predetermined storage container 300, and the output end of the flow pump 100 is connected to a fluid output pipe 400.

It should be noted that the input end of the flow pump 100 may be directly connected to the output port of the predetermined storage container 300. The input end of the flow pump 100 may also be connected to the predetermined storage container 300 through an input pipe, and the input pipe may extend into the bottom of the predetermined storage container 300; alternatively, the input pipe is fixedly connected to the outside of the predetermined storage container 300.

The driving module 200 is configured to receive a parameter of a fluid to be output, generate a driving signal according to the parameter of the fluid to be output, and drive the flow pump 100 according to the driving signal, so that the flow pump 100 determines a target output fluid in the preset storage container 300 according to the driving signal. The driving module 200 is further configured to output the target output fluid to the target container 500 through the fluid output tube 400.

It should be noted that the parameter of the fluid to be output may be a volume of the fluid to be output, such as 200 ml or 300 ml. The fluid delivery control device may further include an input device, such as a digital keypad or a touch screen, through which a user may directly input a desired volume of fluid, and the driving module 200 obtains parameters of the fluid to be output when receiving signals transmitted by the input device.

It should be noted that the driving signal may be a voltage signal, and the voltage signal may be directly transmitted to a power module of the motor, so as to control the rotation speed and the energization voltage of the motor. The driving module 200 may be preset with a conversion rule, and set the corresponding relationship between the rotation speed and the output quantity of the peristaltic pump according to the hardware parameters of the peristaltic pump. For example, a rotation speed of 200rad/min corresponds to an output of 100 ml. When the driving module 200 receives the parameter of the fluid to be output of 100 ml, it may determine that the rotation speed corresponding to the driving signal is 200rad/min, so as to collect 100 ml of fluid in the preset storage container 300. Of course, the conversion relationship between the fluid parameter to be output and the driving signal may be in other manners, and this embodiment is not limited to this.

It should be noted that the inlet of the target container 500 is arranged corresponding to the outlet of the fluid outlet tube 400, the outlet of the fluid outlet tube 400 can be arranged downward, the target container 500 is arranged below the fluid outlet tube 400, and when the fluid outlet tube 400 discharges fluid, the fluid enters the target container 500. The target container 500 may be a container for holding liquid, and when the fluid delivery control device is ready to dispense liquid, the target container 500 is placed under the outlet of the fluid delivery tube 400.

In this embodiment, a driving module receives a parameter of a fluid to be output, generates a driving signal according to the parameter of the fluid to be output, and drives the flow pump according to the driving signal, so that the flow pump determines a target output fluid in the preset storage container according to the driving signal, and outputs the target output fluid to a target container through the fluid output pipe. The output of the flow pump is controlled by adjusting the parameters of the output fluid, different output quantities can be obtained by setting different parameters of the output fluid, and the output quantity of the fluid is flexibly adjustable. In addition, the high reliability of the flow pump also ensures the accuracy of the output.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a second embodiment of the fluid delivery control device of the present invention. Based on the first embodiment, a second embodiment of the fluid conveyance control apparatus of the present invention is proposed.

In the second embodiment, the fluid delivery control device further comprises a reversing valve 600, a liquid outlet pipe 700 and a liquid return pipe 800; the input end of the reversing valve 600 is connected with the fluid output pipe 400; a first output end of the reversing valve 600 is connected with an input end of the liquid outlet pipe 700, and an output end of the liquid outlet pipe 700 outputs the target output fluid to the target container 500; the second output end of the direction valve 600 is connected to the first input end of the liquid return pipe 800, and the output end of the liquid return pipe 800 is connected to the predetermined storage container 300.

It should be noted that the direction valve 600 can switch the first output end or the second output end to communicate with the input end, and certainly can also close the channel, that is, the input end is different from the first output end or the second output end. Specifically, the directional valve 600 may be a directional solenoid valve that may receive a voltage signal to switch between the several modes described above. The voltage signal may be a control signal sent by the driving module 200.

It will be appreciated that fluid may flow from fluid outlet conduit 400 to outlet conduit 700, and thus into target container 500, when the first output is in communication with the input. Further, in order to determine whether the volume of the output fluid is equal to the required volume, the present embodiment provides the liquid outlet pipe 700 with the flow meter 900, and when the fluid flows through the liquid outlet pipe 700, the flow meter 900 records the volume of the fluid, thereby determining whether the volume of the output fluid is equal to the required volume.

It is understood that when the second output end is communicated with the input end, the fluid can flow from the fluid output tube 400 to the fluid return tube 800, i.e., the fluid flows from the predetermined storage container 300 and flows back to the predetermined storage container 300.

It should be noted that, in this embodiment, when the fluid starts to be output, the second output end is firstly communicated with the input end, that is, the fluid forms a circulation in the pipeline. Then an output end is communicated with the input end to output the fluid. The purpose of the circulation is to fill the line with fluid, thereby removing air from the line and avoiding air-induced errors. When the fluid is output, the conduction direction of the reversing valve is switched, the fluid starts to be output, and the volume of the output fluid is accurately controlled by controlling the conduction time of the reversing valve.

It should be noted that, when starting to output, the default state of the reversing valve is that the second output end is communicated with the input end, and when receiving the parameter of the fluid to be output, the driving module 200 firstly outputs a driving signal to the flow pump 100 to operate, so that the fluid circulation is formed in the pipeline; when the control signal is output again, the direction valve 600 is switched to communicate the first output end with the input end to output the fluid. When the output is performed again, the flow rate of the fluid is determined according to the operation parameters of the flow pump, the switching time of the reversing valve 600 is determined according to the parameters of the fluid to be output and the flow rate of the fluid, when the output time of the fluid reaches the switching time, a control signal is output to enable the reversing valve 600 to be switched back to the second output end to be communicated with the input end, the fluid returns to the fluid circulation, meanwhile, a driving signal is output to the flow pump 100 to enable the flow pump to stop running, and the output is finished.

It should be noted that in order to make the output fluid volume more accurate, it is necessary to ensure that there is fluid circulation in the line. Therefore, in this embodiment, the liquid return pipe 800 is further provided with a liquid detection sensor 1000, and when the liquid detection sensor 1000 detects liquid, which indicates that fluid circulation has been formed in the pipeline, the switching valve can be switched to output the fluid. Of course, the directional control valve can also be controlled directly by the operating time of the flow pump 100 to ensure that there is fluid circulation in the line. For example, the flow pump 100 is first energized and after a predetermined time, the reversing valve is switched. The fluid is circulated by setting a time delay; the preset time may be 5 seconds or 8 seconds, and may be freely set by the user, which is not limited in this embodiment.

It should be noted that, in general, the fluid is stored in a sealed manner in order to ensure the quality of the fluid and prevent the fluid from being contaminated. However, a long seal may grow bacteria and the like, which also affects the quality of the fluid. Therefore, in the present embodiment, the fluid delivery control device further includes an on-off valve 900 and a filter 1000; a first end of the switch valve 900 is connected to the second input end of the liquid return pipe 800, a second end of the switch valve 900 is connected to the first end of the filter 1000, and the other end of the filter 1000 is communicated with the outside air.

It can be understood that, when the on-off valve 900 is opened, air passes through the filter 1000 and then enters the predetermined storage container 300, thereby realizing air circulation and preventing bacterial growth. Specifically, the switching valve 900 may be provided as a check valve or the like. When the fluid is outputted, the on-off valve 900 is closed to prevent the fluid from leaking from the filter during the fluid circulation; when the fluid is not output, the on-off valve 900 is opened to perform air exchange; or the maintenance personnel open the switch valve 900 periodically, for example, for 1 hour a day, to avoid long-term opening, which may result in volatilization of the fluid.

In the second embodiment, the liquid is circulated by arranging the liquid return pipe, so that the pipeline is filled with the liquid before output, air in the pipeline is removed, and errors caused by the air are avoided. When the fluid is output, the fluid is output from the liquid outlet pipe by switching the conduction direction of the reversing valve, and the volume of the output fluid is accurately controlled by controlling the conduction time of the reversing valve. Meanwhile, the ventilation channel is arranged, and the influence on the quality of the fluid due to long-time sealing is avoided.

Referring to fig. 3, fig. 3 is a functional module diagram of a driving module according to a first embodiment of the present invention. Based on the first embodiment and the second embodiment described above, a first embodiment of the drive module of the present invention is proposed. The present embodiment is explained based on the first embodiment.

In the present embodiment, the driving module 200 includes a first processor unit 2001, a driving unit 2003, and an isolation unit 2002, and the isolation unit 2002 is connected to the first processor unit 2001 and the driving unit 2003, respectively; the first processor unit 2001 is configured to receive the parameter of the fluid to be output, and generate a switching signal according to the parameter of the fluid to be output. And an isolation unit 200 configured to receive the switching signal and output the driving signal according to the switching signal. And a driving unit 2003, configured to receive the driving signal, and drive the flow pump according to the driving signal, so that the flow pump determines a target output fluid in the preset storage container according to the driving signal, and outputs the target output fluid to a target container through the fluid output pipe.

It should be noted that, when the first processor unit 2001 receives a signal transmitted by the input device, the parameter of the fluid to be output is obtained through a preset conversion rule. Specifically, the first processor unit 2001 may include a first microprocessor U1, such as STM32F030F4P6, and the predetermined conversion rule refers to a program stored in a chip.

Referring to fig. 4, fig. 4 is a chip pin diagram of the first microprocessor U1.

In this embodiment, the first microprocessor U1 includes a first transmitting terminal TXD1 and a first receiving terminal RXD1, and the first transmitting terminal TXD1 and the first receiving terminal RXD1 are data communication terminals for receiving the parameters of the fluid to be output. The first microprocessor U1 also includes a drive signal output for outputting a drive signal. In the present embodiment, the driving signal output terminal includes a first enable terminal EN1, a first clock terminal CLK1, a first driving terminal DIR1, first to third control terminals DM1 to DM3, and an action signal terminal PLY. The specific operation of each output terminal will be described later with reference to the specific structure of the drive unit 2003.

It should be noted that, the STM32F030F4P6 chip is a mature chip, and its related conventional peripheral circuits (such as a crystal oscillator circuit, a start circuit, or a voltage stabilizing circuit) are mature circuits, which are not described herein again. Meanwhile, peripheral circuits not shown in the subsequent related chips are also mature circuits, and are not described in detail.

Referring to fig. 5, fig. 5 is a schematic circuit diagram of the isolation unit 2002.

In the present embodiment, the isolation unit 2002 includes a photocoupler OCEP and a voltage dividing circuit; a first control end of the photoelectric coupler OCEP is connected with the first processor unit 2001, and a second end of the photoelectric coupler OCEP is grounded; a first output end of the photoelectric coupler OCEP is grounded; a second output end of the photoelectric coupler OCEP is connected with an output end of the voltage division circuit, and an input end of the voltage division circuit is connected with a preset auxiliary power supply; a second output of the optocoupler OCEP is connected to the drive unit 2003.

It should be noted that the voltage divider circuit includes a first resistor R1. Because required pin voltage is different between the GPIO pin between the chip to and avoid the mutual interference between the pin, this embodiment is through setting up optoelectronic coupler OCEP to first microprocessor U1's output signal conversion.

It should be noted that the driving unit 2003 may include a second microprocessor unit U2, and the driving of the flow pump 100 is realized by the second microprocessor unit U2. In particular, the second microprocessor unit U2 may be a TB67S109AFTG driver chip, which is a two-phase bipolar stepper circuit driver equipped with a PWM chopper, and the drive motor of the flow pump is also a stepper motor.

Referring to fig. 6, fig. 6 is a chip pin diagram of the second microprocessor unit U2.

In this embodiment, the second microprocessor unit U2 includes input terminals including a second enable terminal EN2, a second clock terminal CLK2, a second driving terminal DIR2, a fourth control terminal DM4, a fifth control terminal DM5, a sixth control terminal DM6, and a VREF reference voltage terminal; the output terminals include a first output terminal OUT1, a second output terminal OU2T, a third output terminal OUT3, a fourth output terminal OUT4, a fifth output terminal OUT5, a sixth output terminal OUT6, a seventh output terminal OUT7 and an eighth output terminal OUT 8.

It should be noted that, the 8 pins of the output end are combined in pairs to form a phase a positive terminal a +, a phase a negative terminal a-, a phase B positive terminal B +, and a phase B negative terminal B-linked with the stepping motor. If the first output terminal OUT1 and the second output terminal OU2T are connected with the positive terminal B + of the B phase, the third output terminal OUT3 and the fourth output terminal OUT4 are connected with the negative terminal B of the B phase, the fifth output terminal OUT5 and the sixth output terminal OUT6 are connected with the negative terminal a of the a phase, and the seventh output terminal OUT7 and the eighth output terminal OUT8 are connected with the positive terminal a + of the a phase. In actual operation, current flows into the positive end of the phase A of the stepping motor and flows out of the negative end of the phase B of the stepping motor; or flow into the positive terminal of the B phase of the stepping motor and flow out of the negative terminal of the A phase. Both modes of control are determined by the level of the second drive-side DIR 2. The fourth to sixth control terminals DM 4-6 are used for controlling the step resolution. The chip is a mature chip, and the principle of the chip can be used for inquiring a related technical manual, which is not described herein in detail.

Note that, in fig. 5, only the isolation cell 2002 is shown to be disposed between the first enable terminal EN1 and the second enable terminal EN 2. In a concrete implementation, the isolation units 2002 can be further arranged between the first clock terminal CLK1 and the second clock terminal CLK2, between the first driving terminal DIR1 and the second driving terminal DIR2, between the first control terminal DM1 and the fourth control terminal DM4, between the second control terminal DM2 and the fifth control terminal DM5, and between the third control terminal DM3 and the sixth control terminal DM 6.

It should be noted that VCC in the isolation unit 2002 is connected to a preset voltage, specifically, a 5V regulated voltage source, and when the output end of the first microprocessor U1 outputs a high level, a diode in the photoelectric coupler emits light, and the right side is turned on; the input of the first microprocessor U2 is low.

It should be noted that the VREF reference voltage terminal of the second microprocessor chip U2 may be connected to a predetermined voltage through a predetermined CMOS device, and specifically, a 74HC123D element may be used. The control signal input end of the 74HC123D element may be connected to the first clock end CLK 1.

In this embodiment, in combination with the second embodiment, the motion signal terminal PLY of the first microprocessor chip U1 is used for controlling the switching solenoid valve 600. Referring to fig. 7, fig. 7 is a schematic diagram of a switching control circuit of the reversing solenoid valve. The action signal end PLY controls the reversing solenoid valve 600 through the switching control circuit.

It should be noted that the switching control circuit may include a third microprocessor chip U3, and the third microprocessor chip U3 may be a chip MOS transistor, which performs a switching function. In particular, the transistor can be an N-channel field effect transistor of A04406A. The emission set can be connected with 5V auxiliary voltage, when the action signal end PLY is at low level, the triode Q1 is conducted, and the light emitting diode arranged on the collector emits light to prompt the conduction state; a voltage division circuit consisting of a third resistor R3 and a third resistor R4 is arranged on the same collector. The drain D of the N-channel FET is connected to an auxiliary voltage through a commutation valve seat J1. The specific auxiliary voltage may be 24V, and the switching valve seat J1 is connected to the switching solenoid valve 600. After the triode Q1 is conducted, the voltage of the gate G of the patch MOS transistor is at a high level, the drain D and the source S are conducted, and the switching solenoid valve 600 is energized. When the operation signal terminal PLY is at a high level, the reversing solenoid valve 600 is not energized. The conduction position of the reversing solenoid valve 600 is controlled by switching the energization state of the reversing solenoid valve 600.

It should be noted that the fourth microprocessor U4 transmits and receives a wireless signal through the antenna J2, and analyzes the received signal through a preset analysis program to obtain a reference output signal, and then outputs the reference signal to the first logic unit 1303.

In this implementation, the first logic unit 1303 may include a fifth microprocessor U5, specifically, the fifth microprocessor U5 is 74AVC1T45FW 3-7. Referring to fig. 10, a chip pin diagram of the fifth microprocessor unit of fig. 10 is shown.

The third transmitting terminal TXD3 and the third receiving terminal RXD3 of the fourth microprocessor U4 are configured to communicate with the serial display screen 1402. The structure of the second logic unit 1402 may refer to the structure of the first logic unit 1302, and is not described herein again.

To further clarify the interaction process, the following is illustrated by way of example.

The preset fluid classification information displayed by the serial port display 1402 includes 100 ml, 200 ml and 300 ml, and output confirmation information corresponding to each volume data, where the output confirmation information may be a two-dimensional code, and the two-dimensional code includes network address information. If the user needs 200 ml of fluid, corresponding network address information can be carried out by scanning the two-dimensional code corresponding to 200 ml. The user inputs an instruction for obtaining 200 ml in the network address, and specifically, the user can use a mode of inputting a password and the like as a confirmation mode. At this time, the server sends a fluid output command to the communication module, and the rf unit 1302 receives the fluid output command and transmits the received fluid output command to the second processing unit 1301. The second processing unit 1301 analyzes the fluid output instruction to obtain a corresponding identification code, and searches for preset fluid classification information according to the identification code to obtain a target parameter of 200 ml.
