Description

Technical Field

[0001] The invention relates to the technical field of temperature boxes for testing temperature-variable products, and in particular to a hidden and detachable heating temperature control system for a product testing platform. Background Art

[0002] The traditional incubator is a heating box and an insulation box in one, which has safety hazards due to the direct exposure of high-temperature components. The incubator of the present invention adopts a hidden design, which is beautiful and safe. Due to the separate design of the heating box and the insulation box, the safety hazards caused by the direct exposure of high-temperature components are reduced, and the risk of operators being scalded is reduced.

[0003] Most traditional temperature chambers are of an integrated sealed type and cannot detect some products that require electrical connection to the outside world. The temperature chamber of the present invention is designed as a detachable structure, which is convenient for freely switching between normal temperature and high temperature environments for measurement operations. This design allows the temperature chamber to be quickly converted to a normal temperature environment when high temperature testing is not required, thereby improving operational flexibility. The design of the present invention also includes a bolt structure between the incubator and the test bench and a convenient center-opening door shaft, which improves the convenience of operating the temperature chamber and makes the product testing process more efficient.

The heating adjustment mode is divided into coarse adjustment and fine adjustment. A total of five heating rods are used, four of which are used for coarse adjustment. After each is selected, the default is the maximum power state, and each can increase by 25.00℃. The fifth is used for fine adjustment, and the adjustable range is 0.00℃~25.00℃. Overall, the temperature can be raised to about 125.00℃.

[0036] More specifically, an air outlet motor 16 is fixedly installed on the inner wall of the heating box 5, and the fan blades at the rotating end of the air outlet motor 16 extend into the air outlet pipe 7. An air intake motor 17 is fixedly installed on the inner wall of the heating box 5, and the fan blades at the rotating end of the air intake motor 17 extend into the air intake pipe 8. A rear end temperature sensor 18 is fixedly installed on the top of the heating box 5.

[0037] Furthermore, the touch screen 10 controls the heating rod 6 to increase the internal temperature of the heating box 5, starts the rotation of the air intake motor 17 to drive the fan blades, so that the hot air enters the insulation box 2 from the heating box 5 through the air intake duct 8, and starts the rotation of the air outlet motor 16 to drive the fan blades, so that the hot air enters the heating box 5 from the insulation box 2 through the air outlet duct 7, forming a hot air circulation.

[0045] Please refer to Figure 5 and Figure 6 The present invention provides a hidden and detachable heating and temperature control system for a product testing platform, and the heating and temperature control steps are as follows:

[0046] Step 1: Set the temperature value through the touch screen 10, write the temperature setting value into the comparator, and then input it into the intelligent control link from the comparator. The intelligent control link controls the actuator to execute, and the front-end temperature sensor 13 detects the output temperature;

[0047] Step 2: The temperature setting value is input into the feedforward control link. The feedforward control link detects that the external ambient temperature will change, converts the external temperature into a data value, adjusts the heating power of the heating rod 6 in advance, and inputs the obtained value into the intelligent control link;

[0048] Step 3: The output temperature value is fed back to the comparator through the feedback link, and the temperature setting value is compared with the fed-back output temperature data value.

[0049] 10. A hidden and detachable heating and temperature control system for a product testing platform according to claim 1, characterized in that the heating temperature adjustment process steps are:

[0050] Step 1: Turn on the relevant components through the touch screen 10, and detect the room temperature, front temperature and rear temperature to form data values, and calculate the difference between the rear temperature and the set value;

[0051] Step 2: Calculate the large, medium and small data values ​​of the difference between the rear end temperature and the set value, and adjust them accordingly;

[0052] Step three, the corresponding large output and calling the experience curve, medium output and calling the experience curve and small output and calling the experience curve can be flexibly adjusted, and the data values ​​of the large output and calling the experience curve, the medium output and calling the experience curve and the small output and calling the experience curve are input into the I / O adjustment and analog quantity adjustment, and then the I / O adjustment and analog quantity adjustment reference data are used to perform cyclic temperature adjustment and adjust the temperature in real time.

[0053] The core control method includes feedforward control link and intelligent control link. The main control idea is:

[0054] First, when the temperature control system is just started, the front temperature sensor 13 and the rear temperature sensor 18 are detected to obtain the current ambient temperature data, which are one of the main bases for selecting the experience curve later;

[0055] Second, the difference between the real-time detection value of the rear temperature sensor 18 and the temperature setting value is calculated, and the number of heating rods 6 to be put into use and the empirical curve to be referred to are determined according to the difference;

[0056] Third, when the difference between the real-time detection value of the rear temperature sensor 18 and the temperature setting value is small, most of the heating rods 6 are cut out, and the voltage values ​​of the remaining heating rods 6 are adjusted according to the experience curve;

[0057] Fourth, when the real-time detection value of the rear temperature sensor 18 is equal to the temperature setting value, the voltage of a heating rod 6 is adjusted to stabilize the voltage near the setting value;

[0058] Fifth, during the entire adjustment process, the value of the front temperature sensor 13 and the ambient temperature value are important bases for selecting the experience curve, and the value of the front temperature sensor 13 is the main basis for active control (Note: Cutting out the heating rod 6 and putting in the heating rod 6 correspond to Figure 4 The I / O adjustment in the circuit is as follows: Figure 4 analog quantity adjustment in ).

[0059] When the present invention is working: the temperature heating box 5 uses a high-power heating rod 6 to heat the surrounding air, and the temperature heating box 5 is connected to the insulation box 2 through two pipes, a fan is installed in each of the two pipes, and air flow is used to achieve heat transfer in a reciprocating cycle; in terms of control, the front-end temperature sensor 13 and the rear-end temperature sensor 18 are fully utilized, and an active control strategy combining feedforward control and feedback intelligent control is used to reduce the delay and lag problems in the heat transfer process, thereby ensuring good dynamic performance and steady-state performance of the system in the entire control process.

[0060] Example:

[0061] The adopted heating adjustment mode is divided into coarse adjustment and fine adjustment. A total of five heating rods 6 are used, four of which are used for coarse adjustment. Each one is set to the maximum power state by default after selection, and can increase 25.00℃. The fifth one is used for fine adjustment, and the adjustable range is 0.00℃~25.00℃. Overall, the temperature can be increased by about 125.00℃.

[0062] The system of the present invention has two temperature sensors, one is located in the heating box 5 and the other is located in the insulation box 2. The temperature sensor in the heating box 5 (the front-end temperature sensor 13) can perform feedforward predictive control on the temperature of the insulation box 2 in combination with the ambient temperature, and call the experience curve drawn in advance during control; the temperature sensor in the insulation box 2 (the rear-end temperature sensor 18) mainly adopts fuzzy intelligent control, which not only ensures the dynamic performance of the control, but also ensures the problem performance of the control; in the overall control, the intelligent control link needs to call the data of the front-end temperature sensor 13 for active adjustment to solve the transmission delay and lag problems in the heat exchange process and the control process.

[0063] The system's incubator 2 adopts a hood-type structure. The object to be measured is placed on the workbench, and the incubator is covered on the object to be measured. There are buckles around the incubator to fix the incubator on the workbench. Two measuring holes are set on the workbench, one is the temperature sensor installation hole, and the other is a reserved hole to meet different needs.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
