At the same time, the touch-operable display screen 3 can display various data of the silver needle heater body 1 when it is in use, making it convenient to view the data during use.

[0033] like Figure 1As shown, a heating sleeve probe 6 and a heating clamp probe 7 are installed at one end of the probe output 5 away from the output channel 4, the heating sleeve probe 6 is installed on the right probe output 5, and the heating clamp probe 7 is installed on the left probe output 5. The heating sleeve probe 6 and the heating clamp probe 7 are installed on different probe outputs 5, so that the heat source is provided to the heating sleeve probe 6 and the heating clamp probe 7 through the probe output 5. A silver needle is installed at one end of the heating sleeve probe 6 and the heating clamp probe 7 away from the probe output 5, and a base 8 is installed at the lower end of the silver needle heating instrument body 1, and a universal wheel 9 is installed at the lower end of the base 8. The silver needle at the end of the heating sleeve probe 6 and the heating clamp probe 7 away from the probe output 5 is set in an optional manner.

[0034] Specifically, when the silver needle warming device body 1 is in use, it is heated by the ceramic heating plate, and the heated heat is transmitted to the probe output 5 through the output channel 4. The probe output 5 transmits the heat to the heating sleeve probe 6 and the heating clamp probe 7. Then, by installing the silver needle at the end of the heating sleeve probe 6 and the heating clamp probe 7 away from the probe output 5, the patient can be treated with the silver needle.

[0035] The device control module is installed in the silver needle heater body 1, and the device control module includes a device control component, a voice component and a safety protection component; the silver needle heater body 1 is controlled by the device control module to realize the start and stop operations of the silver needle heater body 1.

[0036] Specifically, the device control component is electrically connected to the touch-operable display screen 3, and the instructions set on the touch-operable display screen 3 are transmitted to the device control component, thereby realizing the control of the silver needle warmer body 1. By electrically connecting the touch-operable display screen 3 and the device control component, when in use, the operator can issue instructions to the device control component by operating the touch-operable display screen 3, so as to start and stop the device through the device control component.

The false trigger function prevents the sending of false operation information, and the password control login function prevents non-professionals from logging in and operating. The safety protection component is used to increase the safety protection when the silver needle warming device body 1 is used to ensure the safety of use.

[0038] The temperature control module is installed in the silver needle heater body 1. The temperature control module is used to independently monitor each output channel 4. The temperature control module uses the method of tuning PID coefficients to perform temperature control. The method of tuning PID coefficients to output PWM pulses achieves the purpose of temperature control heating and controls the ceramic heating plate to heat to the set temperature. The temperature control module is electrically connected to the equipment control module, and the tuning PID coefficients are provided with temperature monitoring components, temperature control components and over-temperature warning components. By installing the temperature control module in the silver needle heater body 1, the temperature provided by the output channel 4 can be monitored and controlled through the temperature control module. The tuning PID coefficient is to achieve automatic adjustment of temperature through PID, so that the temperature control is accurate.

[0039] Specifically, in order to achieve accurate control of the temperature of the ceramic heating plate, the temperature is controlled by setting a temperature control module, and the temperature control module controls the temperature by tuning the PID system. Therefore, when adjusting the temperature, it is necessary to compare the actual temperature with the set temperature so as to adjust the temperature through PID. Since the temperature control module is used to independently monitor each output channel 4, the temperature of each output channel 4 can be independently monitored and controlled by tuning the PID coefficient.

[0040] The temperature control module uses the method of tuning PID coefficients to achieve the control of the temperature of each independent output channel 4 and the ceramic heater through software; in hardware control, the corresponding PWM waveform is generated according to the ARM DataSheet, and the control signal is accurately output to the optocoupler and power tube to turn on or off the heating power supply, thereby accurately controlling the real-time temperature of each independent output channel 4 and the ceramic heater.

[0041] Preferably, in order to realize the temperature monitoring and control of each independent output channel 4 and the ceramic heating plate, the software is used to measure the temperature and the hardware is used to control the on and off of the heating power supply through a combination of software and hardware, thereby realizing the measurement and control of the temperature.

[0042] The algorithm for tuning the PID coefficient is to measure and control the temperature by independently calculating the deviation between the real-time temperature and the target temperature for each channel. Based on the PID temperature control theory and the performance characteristics of the silver needle and the ceramic heater, the set temperature is compensated by big data statistics, and the PID coefficient is continuously optimized. Finally, the PWM duty cycle is adjusted according to the tuned PID coefficient, and the PWM pulse is output to control the heating hardware. Negative feedback control is used to make the temperature reach the steady-state value of the set value.

[0043] The temperature monitoring component is provided with a dedicated temperature measurement integrated IC for temperature measurement, and the temperature measurement integrated IC is electrically connected to the touch-operated display screen 3. Based on the temperature measurement of the dedicated temperature measurement integrated IC, strictly follow the DataSheet of the temperature measurement IC, use ARM to control the CLK and Dat data lines, and read the real-time temperature and status values. Thus, the implementation temperature and status values ​​provided by the temperature measurement integrated IC are used to enable PID to obtain the temperature corresponding to the ceramic heating plate and each output channel 4. And the temperature will be transmitted to the touch-operated display screen 3, so that the temperature corresponding to the ceramic heating plate and each output channel 4 can be displayed through the touch-operated display screen 3.

[0044] like Figure 3 to Figure 5 As shown, the temperature measurement of the temperature measuring integrated IC is strictly in accordance with the DataSheet timing of the temperature measuring IC and ARM. Through ARM controlling the address lines TSELA0, TSELA1 and TSELA2, the clock signal TCLK and the chip select signal CS0_7, every two groups are read in parallel, and each channel data line SO0, SO1, SO2, SO3, SO4, SO5, SO6 and SO7 are read independently, so as to obtain the real-time temperature and status value of each channel.

[0045] The temperature control component is provided with a temperature setting area, a temperature comparison area and a temperature control area. The temperature setting area is used to set the output temperature range, the temperature comparison area is used to compare the real-time temperature with the set temperature in real time, and the temperature control area makes real-time control according to the difference between the real-time temperature and the set temperature. The temperature control component is used to ensure that the temperature transmitted in the output channel 4 is within the range to be controlled in real time, so as to achieve accurate control of the temperature.

[0046] Specifically, Figure 2 to Figure 4 As shown, the method of adjusting the temperature corresponding to the ceramic heater and each output channel 4 by tuning the PID coefficient is to set the temperature control range of the ceramic heater and each output channel 4 respectively on the tuning PID coefficient, and the temperature corresponding to the ceramic heater and each output channel 4 will be monitored in real time by the temperature measurement integrated IC. When the monitored temperature is compared with the corresponding set value, if there is a deviation, the tuning PID coefficient will send information to the hardware control, and the temperature will be regulated by turning the heater on and off, so that the temperature is restored to the range that needs to be controlled.

[0047] Preferably, the principle of temperature-controlled heating is to optimize the control coefficient based on the negative feedback control algorithm, combine the performance characteristics of the silver needle and the ceramic heater, calculate the tuned PID coefficient regularly, accurately output PWM pulses, control 164CLK1, 164CLK2, 164CLK3, 164CLK4 and Q24GRP1, Q23GRP2, Q22GRP3, Q21GRP4 outputs, and give control signals to the optocoupler and power tube to turn on or off the heating power supply, thereby accurately controlling the real-time temperature.

[0048] The over-temperature warning component is equipped with an over-temperature setting area, an over-temperature comparison area and an early warning prompt area. The over-temperature setting area is used to set the range of the upper and lower limits of the temperature. The over-temperature comparison area is used to compare the real-time temperature with the set stability in real time. The early warning prompt area is used to warn after over-temperature. The over-temperature warning component warns of abnormal temperatures transmitted by output channel 4. The over-temperature warning component sets the upper and lower limits of the temperature control by tuning the PID coefficient so that an alarm is issued when the temperature exceeds the limit.

[0049] like Figure 7 As shown, ARM obtains the real-time fault status value by reading the data line 164DIN.

[0050] When in use, when treating a patient through the silver needle warming device body 1, it is necessary to set the temperature to be controlled for each output channel 4. Specifically, the temperature control range corresponding to the ceramic heating plate and each output channel 4 is set by adjusting the PID coefficient. The temperature corresponding to the ceramic heating plate and each output channel 4 is monitored in real time through the temperature measurement integrated IC. When the monitored temperature is compared with the corresponding set value, if there is a deviation, the tuning of the PID coefficient will send information to the hardware control, and the temperature will be regulated by turning the heater on and off, so that the temperature is restored to the range that needs to be controlled.
