In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example 1
As shown in fig. 1, the present invention provides an infusion detection controller, which comprises an infusion signal detection module, a signal amplification module, a core control module, an audible and visual alarm module, an LCD display module, a constant temperature heating module and an external device control module;
the infusion signal detection module, the signal amplification module and the core control module are sequentially connected;
the core control module is respectively connected with the external equipment control module, the LCD display module, the constant-temperature heating module and the acousto-optic alarm module;
the infusion signal detection module is used for detecting liquid information in the infusion bottle and converting the liquid information into an electric signal;
the infusion signal detection module is used for processing capacitance signal change caused by infusion signal change by taking a self-made copper sheet as a simple parallel plate capacitor according to the principle of a parallel plate capacitance sensor, when the parallel plate capacitor detects that water exists, the output of the sensor module still has low level, the low level lasts for 400us, and the requirement cannot be met by adopting a single chip microcomputer shake elimination method, so that the capacitance is increased at an output port to eliminate shake of signals. Because the infusion signal detection module can output the oscillatory square wave signal when no water exists, the high and low levels respectively last for 150us, the capacitor only can make the waveform slow, and the singlechip still can identify the high and low levels, so that the addition of the capacitor is advisable. At the moment, the single chip microcomputer can realize signal monitoring only by judging the level of entering P1.2.
The embodiment adopts a common infusion treasure as an infusion signal detection module, which can reduce the circuit cost and keep the sensor with high sensitivity.
The signal amplification module is used for amplifying the signal acquired by the infusion signal detection module;
because the high level of the signal acquired by the parallel plate capacitance sensor after being processed by the sensing module is not less than 3V, and the level can not be accurately identified by the singlechip, a signal amplification module is added, when the module outputs the high level, the base electrode of the triode is conducted, and the output voltage is low voltage; when the module outputs low level, the triode can not be conducted, and the output voltage is 5V. The signal amplification module circuit of the present embodiment is shown in fig. 2.
The core control module is used for processing the amplified signal;

the acousto-optic alarm module of the embodiment adopts an LED circuit level buzzer, the LED circuit adopts a low-level effective working mode, and a protective resistor is connected in series. The buzzer is large in power consumption, so that the current needs to be amplified by the triode when the singlechip is driven, the effective working mode of low level is also adopted, when the low level is output by the port P1.0, the triode is conducted, and the voltage at two ends of the buzzer is 5V, so that the working voltage is reached. The circuit of the acousto-optic alarm module of the embodiment is shown in FIG. 4.
The LCD display module is used for displaying the infusion time;

When the current temperature is lower than 37 ℃, the mercury column leaves the upper connecting wire, the relay circuit is disconnected, the relay is nonmagnetic, and the metal sheet on the relay is upwarped under the pulling force of the spring, so that the circuit of the circuit 2 is closed smoothly to heat the electric heating wires A and B; when the present temperature was higher than 37 ℃, mercury thermal expansion reached last wiring, and the relay circuit is closed unobstructed, and the relay coil produces magnetism and inhales the sheetmetal above the relay, leads to circuit 2's circuit disconnection, can't make the heating wire heating again, and these two processes play the effect of constant temperature 37 ℃ heating.
And the external equipment control module is used for controlling the step number of the stepping motor in the external equipment according to the instruction sent by the core control module so as to control the flow rate of the liquid in the infusion tube and the cut-off closing and opening of the liquid in the infusion tube.
