[0036] Please refer to Figure 1 and Figure 4 , Figure 1 This is a flow chart of a method for controlling the temperature of a heated breathing circuit with a temperature correction function provided in an embodiment of the present application. Figure 4Schematic diagram of a heating breathing circuit temperature control system with a temperature correction function provided in an embodiment of the present application. The heating breathing circuit temperature control system 1000 specifically includes a heating circuit 100, a microprocessor 200, a function selection circuit 300, a temperature sampling circuit 400 and a short-circuit circuit 500. Among them, the heating circuit 100 includes a temperature sensor 101. The microprocessor 200 includes a sending module 201, a conversion module 202, a calculation module 203 and an operation module 204. Among them, the sending module 201 is used to send instructions to heat the heating circuit 100 within a preset first time, and the preset first time is the time for continuously heating the heating circuit 100. The conversion module 202 is used to convert the first temperature signal to obtain the resistance value of the temperature sensing circuit. The calculation module 203 is used to obtain the resistance value of the temperature sensor 101 through the resistance value of the temperature sensing circuit, the resistance value of the resistance wire and the resistance value of the internal resistance of the temperature sampling circuit 400. The resistance value of the resistance wire is pre-set in the microprocessor 200. The operation module 204 is used to calculate the resistance value of the temperature sensor 101 and the temperature of the temperature sensor 101 using a preset conversion formula to obtain the actual temperature value of the heating pipeline 100. Among them, the function selection circuit 300 includes a control module 301. The control module 301 is used to control the processing items when the microprocessor 200 adopts a time-sharing multiplexing method. The temperature sampling circuit 400 is connected to the heating pipeline 100 through the function selection circuit 300 to transmit the first temperature signal in the heating pipeline 100 to the microprocessor 200 within a preset second time, and the preset second time is used for temperature sampling. The short circuit 500 is connected to the temperature sampling circuit 400 through the function selection circuit 300, and is used to obtain the resistance value of the internal resistance of the temperature sampling circuit 400 within a preset third time according to the instruction of the microprocessor 200. The preset third time is the sampling time of the circuit internal resistance. The total time of the preset first time, the preset second time and the preset third time is a control cycle time, and the preset first time is the longest. Among them, the temperature control method of the heated breathing circuit with temperature correction function specifically includes the following steps S102-S112.

[0037] Step S102, the microprocessor 200 heats the heating pipe 100 in a preset first time through the function selection circuit 300 in a time-division multiplexing manner. The preset first time is the time for heating the heating pipe 100 continuously. The function selection circuit 300 controls the processing items of the microprocessor 200. It can be understood that the heating pipe 100 Figure 5The structure of the heating pipeline 100 is shown. The heating pipeline 100 includes: resistance wires R1 and R2, a pipeline joint 102, and a temperature acquisition device 103. The temperature acquisition device 103 includes a temperature sensor 101 and a diode 1031. Before the heating breathing pipeline temperature control system 1000 with temperature correction function works, the total processing cycle duration needs to be preset. The microprocessor 200 sends an instruction to heat the heating pipeline 100 through the function selection circuit 300 during the first period of the total processing cycle. The function selection circuit 300 is provided with a switch to periodically connect the microprocessor 200 with other functional circuits at each stage of the total processing cycle duration.

[0038] Step S104, the microprocessor 200 obtains the first temperature signal in the heating pipeline 100 through the function selection circuit 300 within the preset second time. The heating pipeline 100 contains a temperature sensor. The heating pipeline 100 is connected to the temperature sampling circuit 400 through the function selection circuit 300 within the preset second time. The preset second time is used for temperature sampling. It can be understood that when the total processing cycle reaches the second stage, the function selection circuit 300 will open the connection between the heating pipeline 100 and the temperature sampling circuit 400, and let the microprocessor 200 send an instruction to the temperature sampling circuit 400 to obtain the temperature of the temperature sensor in the heating pipeline 100 to obtain the first temperature signal.

[0039] In step S106, the microprocessor 200 converts the first temperature signal to obtain the resistance value of the temperature sensor circuit. It can be understood that after the microprocessor 200 obtains the first temperature signal, it performs a digital-to-analog conversion on the first temperature signal, and calculates the resistance value of the temperature sensor circuit according to the temperature value corresponding to the converted digital signal.

[0040] Step S108, the microprocessor 200 obtains the resistance value of the internal resistance of the temperature sampling circuit 400 by connecting the temperature sampling circuit 400 with the short circuit 500 through the function selection circuit 300 within the preset third time, the preset third time is the sampling time of the circuit internal resistance, the total time of the preset first time, the preset second time and the preset third time is a control cycle time, and the preset first time is the longest. It can be understood that after measuring the temperature value in the heating pipeline 100, the function selection circuit 300 will open the connection between the temperature sampling circuit 400 and the short circuit 500 to obtain the internal resistance value of the temperature sampling circuit 400 in the third stage, that is, the last stage of the total processing cycle length, for subsequent correction of the temperature value.

[0041] In step S110, the microprocessor 200 obtains the resistance value of the temperature sensor through the resistance value of the temperature sensing circuit, the resistance value of the resistance wire and the resistance value of the internal resistance of the temperature sampling circuit 400. The resistance value of the resistance wire is preset in the microprocessor 200. It can be understood that after the resistance value of the temperature sensing circuit and the resistance value of the internal resistance of the temperature sampling circuit 400 are obtained according to step S106 and step S108, the microprocessor 200 calculates the resistance value of the temperature sensing circuit and the resistance value of the internal resistance of the temperature sampling circuit 400 according to the preset calculation formula for calculating the resistance of the temperature sensor. The calculation formula is: R t =R all -R inter -R 1 -R 2 , where R t is the resistance of the temperature sensor, Rall is the resistance value of the temperature sensing circuit, R inter is the resistance value of the internal resistance of the temperature sampling circuit 400, and R1 and R2 are the resistance values ​​of the resistance wire.

[0042] In step S112, the microprocessor 200 uses a preset conversion formula to calculate the resistance value of the temperature sensor and the temperature of the temperature sensor to obtain the actual temperature value of the heating pipeline 100. It can be understood that after the microprocessor 200 obtains the resistance value of the temperature sensor, the microprocessor 200 will calculate the actual temperature value of the heating pipeline 100 according to the preset conversion formula, that is, the preset conversion formula is: Among them, T 2 is the actual temperature value of the current cycle, T 1 is the temperature of the temperature sensor, B is the thermal sensitivity index of the thermistor, wherein the thermistor is the temperature sensor in this embodiment, and R is the temperature of the thermistor at T 1 Rt is the resistance of the temperature sensor.

[0043] In the above embodiment, by adding the short-circuit circuit 500, the content of the temperature sampling circuit 400 is measured, the influence of the temperature drift error of the electronic components of the temperature sampling circuit 400 on the temperature transmission sampling of the heating pipeline 100 is eliminated, and the accuracy of temperature control is improved.

[0044] Please refer to Figure 2 , which is the first sub-flow chart of the method for controlling the temperature of a heated breathing circuit with a temperature correction function provided in an embodiment of the present application. Step S104 specifically includes the following steps S202-S204.

[0045] In step S202, the microprocessor 200 connects the heating control circuit to the heating pipeline 100 through the function selection circuit 300. The heating control circuit is used to control the output of gas in different temperature ranges. It can be understood that in order to effectively ensure that the temperature in the heating pipeline 100 is within a preset temperature range, the heating pipeline 100 is connected to the heating control circuit, so that the temperature control is more convenient.

[0046] In step S204, the microprocessor 200 uses the heating control circuit to output different duty ratios so that the gas temperature of the heating pipeline 100 is controlled within the set temperature range. It can be understood that the duty ratio refers to the proportion of the power-on time to the total time in a pulse cycle. In order to ensure that the temperature in the heating pipeline 100 is always within the preset temperature range, it is necessary to input different duty ratios to heat the heating pipeline 100 in some special cases, so as to ensure that the temperature value in the heating pipeline 100 is always within the set temperature range.
