A temperature sensor 13 is used to collect the temperature within the facility. The analog signal output by the temperature sensor 13 is converted to a digital signal by a temperature transmitter 14 and transmitted to a processor for real-time processing of the temperature data.

[0036] The temperature acquisition device of the medical waste treatment equipment of this embodiment can realize real-time monitoring of the internal temperature of the equipment, improve the safety and reliability of equipment operation, and facilitate management personnel to promptly discover and deal with potential problems.

There is a temperature measuring cable 15 in the first channel 111, and the temperature measuring cable 15 is in direct contact with the interior of the medical waste treatment equipment, thereby improving the accuracy of temperature measurement.

[0040] In an optional embodiment of the present invention, a second channel 112 is provided on the side of the shell 11 , and the power line 16 enters the shell 11 through the second channel 112 and is electrically connected to the temperature sensor 13 and the temperature transmitter 14 .

[0041] In this embodiment, a second channel 112 is provided on the side of the housing 11, and a power cord 16 passes through the second channel 11 and enters the housing 11. One end of the power cord 16 is connected to an external power supply device, and the other end is connected to the temperature sensor 13 and the temperature transmitter 14 to supply power to the components inside the temperature acquisition device.

[0045] Temperature measurement circuit 31;

[0046] a signal processing circuit 32 electrically connected to the temperature measurement circuit 31;

[0047] A power supply circuit 33 is electrically connected to the signal processing circuit 32 .

[0052] In the above embodiment, Figure 2 As shown, the temperature sensor 13 uses a high-precision thermocouple or thermistor or inductor, which can work stably in harsh environments such as high temperature and high humidity to ensure the accuracy and reliability of the data. The temperature sensor 13 is connected to the temperature measurement circuit 31 and outputs the temperature signal to the signal processing circuit 32. After the signal processing circuit 32 undergoes voltage stabilization and filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection, the temperature signal is converted into a standard signal that is linearly related to the temperature. These signals can be current signals (such as 4-20mA), voltage signals (such as 0-5V or 0-10V) or digital signals (such as RS485).

[0053] The 4-20mA current signal is one of the standard signals commonly used in industry, with advantages such as strong anti-interference ability and long transmission distance. The 0-5V or 0-10V voltage signal is also a common standard signal, suitable for measurement occasions requiring higher accuracy and resolution. Digital signal output methods such as RS485 are suitable for occasions requiring long-distance transmission and complex communication protocols, and can realize multi-point measurement and centralized control.

[0054] The power supply circuit 33 is arranged at one side of the output end of the signal processing circuit 32 and is electrically connected to the signal processing circuit 32 and the temperature measurement circuit 31 .

[0061] An eighth resistor R8 , a third transistor Q3 , and a second diode D2 are connected in parallel between the signal processing circuit 32 and the power supply circuit 33 .

[0062] The power supply circuit 33 includes: a power supply, a first diode D1 , and a second capacitor C2 . The negative electrode of the power supply is connected to the connection terminal, and the positive electrode of the power supply is electrically connected to the signal processing circuit 32 .

[0063] The temperature inside the medical waste treatment equipment is obtained through the thermocouple L0 in the temperature measurement circuit 31. The first amplifier A1, the second amplifier A2 and the third amplifier A3 in the signal processing circuit 32 convert the analog signal output by the temperature measurement circuit 31 into a digital signal and output it through the terminal.

[0064] In this embodiment, the temperature sensor 13 is electrically connected to the first amplifier A1 and the second amplifier A2, respectively. The first amplifier A1 and the second amplifier A2 amplify the output signal of the temperature sensor 13 to amplify the temperature signal. The amplified signal is then input into the third amplifier A3, which further amplifies the signal to achieve signal processing such as signal combination and weighting, thereby converting the temperature signal into a standard signal.

[0065] Multiple ammeters are also provided between the first amplifier A1, the second amplifier A2 and the third amplifier A3, which can measure the current intensity in the circuit in real time and accurately; when a fault occurs in the circuit, the ammeter can quickly capture abnormal changes in the current.

[0066] The output end of the third amplifier A3 is electrically connected to the output terminal, and is used to output the processed signal to the processor.

[0067] In an optional embodiment of the present invention, the housing 11 is provided with a fixing hole 23 ; a screw 21 is provided in the fixing hole 23 to fix the temperature transmitter 14 on the housing 11 .

[0070] Each screw 21 is sleeved with a spring 22, which can absorb vibration and impact force, and will produce an extrusion buffer between the screw 22 and the temperature transmitter 14 and the housing 11, thereby increasing the friction coefficient between the screw 22 and the temperature transmitter 14, thereby protecting the equipment from loosening due to vibration or thermal expansion and contraction.

[0071] In an optional embodiment of the present invention, the temperature collection device of the medical waste treatment equipment further includes a display device and an alarm device.

[0072] In this embodiment, the display device and the alarm device are both electrically connected to the processor. Figure 3The figure shows the circuit structure of the processor. The processor circuit includes a protection circuit and a data processing circuit, wherein the protection circuit includes an eleventh resistor R11, a twelfth resistor R12, a thirteenth resistor R13, and a fourteenth resistor R14. One end of the eleventh resistor R11 and the twelfth resistor R12 is connected to the power supply, and one end of the thirteenth resistor R13 and the fourteenth resistor R14 is grounded; a fifteenth resistor R15 is connected in parallel with the eleventh resistor R11 and the thirteenth resistor R13, and a sixteenth resistor R16 is connected in parallel with the twelfth resistor R12 and the fourteenth resistor R14; by setting up the protection circuit, the processor circuit is protected to prevent sudden power interruption or large voltage fluctuations, and to protect the components in the circuit from damage.

[0073] The data processing circuit includes a fourth amplifier A4, wherein the first pin of the fourth amplifier A4 is the negative terminal of the gain resistor, the eighth pin is the positive terminal of the gain resistor, and a seventeenth resistor R17 and a fourth capacitor C4 are connected between the first and eighth pins to set the gain of the operational amplifier. The gain value is determined by the resistance value of the resistor. The second pin is an inverting input terminal for receiving a negative input signal to be amplified; the third pin is a non-inverting input terminal for receiving a positive input signal to be amplified; the fourth pin is a negative power supply terminal; the fifth pin is a reference voltage input terminal, which is connected to ground together with the fourth pin and can also be connected to an external reference voltage to adjust the output signal offset; the sixth pin is an output terminal for outputting the amplified signal; and the seventh pin is a positive power supply terminal for providing a positive power supply voltage.

[0074] A third capacitor C3 is connected in parallel between the protection circuit and the data processing circuit. The third capacitor C3 and the fourth capacitor C4 provide additional energy when the power supply is insufficient to maintain the stability of the power supply voltage, thereby protecting the device from damage.

[0075] The processor analyzes collected temperature data in real time to determine the equipment's operating status. When the collected temperature exceeds a preset threshold, the processor issues an alarm command to the alarm device, which then emits an alarm signal. Alarms can be sent in a variety of ways, including audible and visual alarms, text messages, and emails, ensuring operators receive timely alerts. Furthermore, the alarm device can be connected to the medical waste treatment equipment's power supply system. When temperature abnormalities occur, it automatically shuts off the power or activates the cooling system, taking other safety measures to prevent equipment damage or accidents.
