Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more clear, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It will be apparent that the described embodiments are some, but not all, embodiments of the utility model. All other embodiments, which are obtained by a person skilled in the art based on the described embodiments of the utility model, fall within the scope of protection of the utility model.
The method aims at solving the problems that in the prior art, in the white spirit brewing process, the resistivity of fermentation substances in a fermentation tank is difficult to monitor in real time, and the labor cost is high. The application correspondingly provides a fermentation material resistivity detection device, includes: a probe rod; the probe rod comprises a probe rod main body and a probe arranged at one end of the probe rod main body; the probe comprises a humidity probe for collecting resistivity signals of the fermentation substance; the outer surface of the probe rod main body is provided with scales for indicating the depth of the probe rod in the fermentation tank, and a circuit board electrically connected with the probe is integrated inside the probe rod main body; the other end of the probe rod main body is provided with a communication interface, and the communication interface is connected with the circuit board. According to the scheme, the real-time performance of resistivity detection of fermentation substances in the fermentation tank can be improved, the labor cost is reduced, and the quality of white spirit brewing is guaranteed.
Referring to fig. 1 and 2, a schematic structural diagram of a fermenting substance resistivity detection device is provided in one embodiment of the present application.
Specifically, in the embodiment of the present application, a device for detecting resistivity of a fermentation substance includes: a probe rod; the probe rod comprises a probe rod main body 11 and a probe 12 arranged at one end of the probe rod main body 11;
the probe 12 comprises a humidity probe for acquiring resistivity signals of the fermentation material;
the outer surface of the probe rod main body 11 is provided with a scale 111 for indicating the depth of the probe rod in the fermentation tank, and a circuit board electrically connected with the probe 12 is integrated in the probe rod main body;
the other end of the probe rod main body 11 is provided with a communication interface 13, and the communication interface 13 is connected with the circuit board.
Further, the humidity probe is an electrically conductive humidity sensor having a 316 stainless steel housing for contacting the fermenting substance. The 316 stainless steel material does not react with common acid and alkali, can not produce pollution when being contacted with fermented products, can meet the requirements of food grade, and has good strength, high wear resistance and good long-term use stability. In contrast, the 201 stainless steel, 304 stainless steel, copper aluminum and other materials cannot be well applied. Noble metals such as gold, silver, platinum and the like have high manufacturing cost, and the wear-resisting property cannot be considered by using a coating process. Therefore, 316 stainless steel is used as a probe.
In embodiments of the present application, the probe portion may further include a temperature probe. The temperature probe can be arranged between the two humidity probes, for example, a K-type thermocouple sensor can be adopted, and temperature signals of fermentation substances can be accurately acquired.
In the embodiment of the application, since the fermentation process is a complex process, for example, after yellow water in a fermentation tank, the electric signal of the fermentation substance can show fluctuation change, the resistivity signal can also show change of measurement range, and if a sensor with a fixed range is used for measurement, the accuracy is greatly reduced.
In this regard, the embodiment of the application carries out the improvement design to the circuit board in the detection device, realizes the great detection demand of adaptable resistivity change scope.
As shown in fig. 3, on the circuit board, a processor (for example, may be an MCU, etc.), a first operational amplifier circuit and a second operational amplifier circuit are integrated; the input end of the first operational amplifier circuit is connected with the processor, the output end of the first operational amplifier circuit is connected with the second operational amplifier circuit, and bias voltage is output; and the input end of the second operational amplifier circuit is connected with the bias voltage and the humidity probe, the collected resistivity signal of the fermentation substance is amplified, and the output end of the second operational amplifier circuit is connected with the processor.
Fig. 4 illustrates a specific circuit schematic of a circuit board.
P1 is binding post, is connected with humidity probe signal, and R5 is pull-up resistor, and D1 is static and surge protection diode. The part converts the resistivity of the ferment contacted with the probe into weak electric signals and is used as a first input end of a second operational amplifier circuit.
The second operational amplifier circuit comprises devices such as R6, R8 and R9 to form an in-phase proportional amplifier, and amplifies the weak electric signal, so that the measurement accuracy and resolution are effectively improved.
A second input of the second operational amplifier circuit is connected to a bias voltage (+v_offset). When the resistivity changes widely, the bias voltage (+v_offset) of the R8 input needs to be changed, so that the output of the operational amplifier is prevented from being saturated, and the amplifying and measuring capacity of the signal is lost.
The bias voltage (+v_offset) is generated by the first operational amplifier circuit of U2. The first input end of the first operational amplifier circuit is connected with the PB0 pin of the microprocessor. The second input end of the first operational amplifier circuit is connected with the output end. The principle of the first operational amplifier circuit is that PWM waves generated by changing a PB0 pin of a microprocessor are filtered by a low-pass filter formed by R4 and C10 to generate a controllable direct-current voltage signal, and after the load capacity is improved by a voltage follower formed by the operational amplifier, a bias voltage (+V_offset) signal is output.
Therefore, the circuit board skillfully utilizes the characteristic that the reverse input end of the in-phase proportional amplifying circuit is adjustable, when the resistivity changes in a larger range, the offset voltage can be changed, the unsaturation of the amplifier is kept, and the advantages of both the detection precision and the detection range are achieved.
In the embodiment of the application, the processor may process the amplified signal and output the signal to other visually monitored electronic devices, for example.
Referring to fig. 5, an application scenario of the device for detecting resistivity of a fermentation substance in the embodiment of the present application is illustrated. In this scenario, the system includes a data acquisition end 1 and a display control end 2. The data acquisition end 1 mainly comprises a fermentation substance resistivity detection device in the embodiment of the application, and acquires a resistivity signal of a fermentation substance through a humidity probe and transmits the resistivity signal to an internal circuit board for processing, and the circuit board transmits processed data to the display control end 2 through a communication interface. The communication interface may be, but is not limited to, an RS485 communication interface, which employs the Modbus communication protocol.
In summary, the device for detecting resistivity of a fermentation substance provided by the embodiment of the application comprises a probe rod; the probe rod comprises a probe rod main body and a probe; the probe rod main body is provided with scales, so that the probe rod can be conveniently placed at different depths of the fermentation tank manually, and the labor complexity is reduced; the probe is provided with the humidity probe, can collect the resistivity signal of the fermentation material in the fermentation tank, and transmits the circuit board inside the probe rod main body, and the circuit board can further transmit the data to the outside through the communication interface, so that the real-time monitoring of the moisture of the fermentation material in the brewing process can be realized.
