[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example
[0022] See also Figure 1-3 , in the figure: This embodiment is a preferred implementation of the technical solution, a PID constant temperature control mechanism, including a temperature sensor detector 1, a driving component 2 for moving the position of the temperature sensor detector 1 and a PID regulator 3 connected to the temperature sensor detector 1; the driving component 2 includes a base 21, a telescopic rod 22 fixed to the upper side of the base 21, and a mounting block 23 fixed to the end of the telescopic rod 22; the temperature sensor detector 1 includes a detector body 11 fixed to the outside of the mounting block 23, a protective cover 12 arranged outside the detector body 11, a heat-conducting column 13 and an output port 14 connected to the detector body 11, and a probe 15 fixed to the end of the heat-conducting column 13; the PID regulator 3 is wirelessly connected to the temperature sensor detector 1, and the PID regulator 3 has a built-in data processing unit;
[0023] It should be noted that: in the PID constant temperature control mechanism involved in the present application, by setting the linear drive of the temperature sensor detector 1 by the driving component 2, a single temperature sensor detector 1 can detect the temperature of multiple positions, and the PID regulator 3 can compare and process the temperature data to accurately adjust the operation of the external temperature control component. At the same time, the temperature sensor detector 1 that moves in multiple positions replaces the temperature detection structure currently installed in a fixed position, which can improve the temperature detection result. At the same time, compared with the temperature detection method of the temperature detection structure installed in multiple positions, its investment cost is relatively small, and the operation is convenient and efficient. Specifically, the telescopic end of the telescopic rod 22 drives the mounting block 23 to move linearly. During the movement, it moves synchronously with the temperature sensor detector 1 fixed thereto. The probe 15 in the temperature sensor detector 1 is responsible for detecting the temperature, and the temperature information is further transmitted by the heat conductive column 13. Finally, the temperature information is converted into circuit information inside the detector body 11 and transmitted to the data processing unit in the PID regulator 3. The intelligent unit built into the PID regulator 3 intelligently analyzes and processes the temperature information to complete the temperature control cycle to ensure the constant temperature effect.
[0024] Among them Figure 1 and 2 As shown, the protective cover 12 is fixed to the outside of the outer mounting block 23, and a sealed wiring port is provided on the side of the protective cover 12; the heat-conducting column 13 passes through the protective cover 12, and two heat-conducting columns 13 are provided in parallel; the output port 14 is connected to the PID regulator 3 via a wire;
[0025] It should be noted that: the protective cover 12 is used to protect the detector body 11, and a wiring port is provided for connecting the detector body 11 to the external wiring. The end of the thermally conductive column 13 is located outside the protective cover 12 and contacts the detection sample. The thermally conductive column 13 and the probe 15 are arranged in a one-to-one correspondence. There are two thermally conductive columns 13, so that there are also two corresponding probes 15. When performing temperature sensing detection, the two probes 15 work at the same time, which improves the accuracy of temperature detection and can also avoid the failure of one of the probes 15 that causes the temperature detection work to be unable to continue.
[0026] Among them Figure 3 As shown, the PID regulator 3 is also provided with an execution unit, a communication unit and a constant temperature setting unit; the output end of the execution unit is connected to the external temperature control component, and the input end of the execution unit is connected to the data processing unit; the communication unit is connected to the management end data exchange, and the communication unit is also connected to the data processing unit; the constant temperature setting unit is connected to the data processing unit
[0027] It should be noted that: the execution unit is used to execute the execution instructions issued by the data processing unit, the communication unit is used for the wireless connection between the PID regulator 3 and the management end, and transmits information to the management end while also receiving the instructions issued by the management end. The constant temperature setting unit is used to set the temperature comparison threshold. When the above-mentioned intelligent unit is actually running, the temperature information detected by the temperature sensor detector 1 is converted into a circuit signal and then transmitted to the data processing unit in the PID regulator 3. The data processing unit converts the circuit information into digital information and compares it with the preset value in the constant temperature setting unit. According to the comparison result, a corresponding instruction is issued to the execution module, and then the operating state of the external temperature control component is controlled through the execution module. At the same time, the temperature information is transmitted to the management end via the communication unit to assist the intelligent judgment of the management end. The management end can also issue instructions to the data processing module through the communication module to modify the preset value of the constant temperature setting module and adjust the operating state of the external temperature control component.
