[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0030] Please refer to Figures 4 to 10 The utility model provides a temperature sensing package testing device, which is used for performing a heating test on the temperature sensing package. The temperature sensing package testing device includes: a test bench 1, a power supply unit 2, a temperature control unit 3 and a first control unit 4. The test bench 1 is provided with an experimental space 10 for placing the temperature sensing package; the power supply unit 2 is connected to one end of the temperature sensing package; the temperature control unit 3 is arranged on the inner wall of the experimental space 10, and is used to increase the temperature in the experimental space 10 to a preset temperature and collect the temperature in the experimental space 10; the temperature control unit 3 is electrically connected to the power supply unit 2; the first control unit 4 is electrically connected to the power supply unit 2, the other end of the temperature sensing package away from the power supply unit 2 is connected to the first control unit 4, and the first control unit 4 is communicatively connected to the temperature control unit 3, the first control unit 4 is used to control the operating state of the temperature control unit 3, to obtain the temperature in the experimental space 10 and the resistance value of the temperature sensing package, to determine whether the temperature sensing package will fail during the temperature rise process, and to determine whether the temperature sensing package fails at a preset temperature within a preset time.

[0031] It can be seen that the temperature sensing package testing device provided by the utility model is simply arranged with a test bench 1, a power supply unit 2, a temperature control unit 3 and a first control unit 4. The test bench 1 is provided with a test space 10 for placing the temperature sensing package. The temperature control unit 3 is arranged on the inner wall of the test space 10. The first control unit 4 is communicated with the temperature control unit 3. The first control unit 4 is respectively connected to the power supply unit 2 and the other end of the temperature sensing package away from the power supply unit 2, so as to control the temperature control unit 3 through the first control unit 4. In addition, the first control unit 4 can also obtain the temperature in the test space 10 and the resistance value of the temperature sensing package, and judge whether the temperature sensing package will fail during the temperature rising process and judge whether the temperature sensing package fails at a preset temperature within a preset time. Thus, the temperature sensing package test device realizes, through the first control unit 4, that during the test process, the temperature sensing package test device monitors the state of the temperature sensing package placed in the experimental space in real time, thereby avoiding the problem that the temperature sensing package fails at a preset temperature during the heating process or within a preset time period and the test continues without being discovered, thereby reducing the test cost and saving the test time. At the same time, through the real-time monitoring of the temperature sensing package test device, the performance of the temperature sensing package can be comprehensively evaluated, the reliability and accuracy of the temperature sensing package test device can be improved, and the test efficiency of the temperature sensing package test device can be improved. The temperature sensing package test device has a simple structure and is easy to operate. It realizes real-time monitoring of the state of the temperature sensing package in the middle of the test, and can effectively solve the technical problem in the prior art that it is impossible to monitor whether the temperature sensing package will fail during the test of the temperature sensing package.

[0032] Among them, the “resistance of the temperature sensing package” in the above “used to obtain the temperature and resistance of the temperature sensing package in the experimental space 10” includes the actual resistance of the temperature sensing package at different temperatures in the experimental space 10 and the ideal resistance of the temperature sensing package at different temperatures in the experimental space 10.

[0033] In the specific implementation process, Figure 6 and Fig.10 As shown, the first control unit 4 is a programmable controller (PLC), and at least part of the power supply unit 2 is used to provide power for various components in the temperature sensing package testing device.

[0034] In actual work, one end of the temperature sensing package is connected to the power supply unit 2, and the other end of the temperature sensing package and the power supply unit 2 are both connected to the first control unit 4, so that the temperature sensing package, the power supply unit 2 and the first control unit 4 form a closed loop circuit. At the same time, the other end of the temperature sensing package is connected to the first control unit 4, which not only forms a closed loop circuit, but also facilitates the first control unit 4 to obtain the resistance value of the temperature sensing package.

[0035] In the specific implementation process, the power supply part 2 includes a power supply component 20 and a socket component 21. The power supply component 20 forms at least part of the power supply part 2 (the power supply component 20 is used to provide power for various components of the temperature sensing package test device). The power supply component 20 is electrically connected to the first control part 4 and the socket component 21 respectively. The socket component 21 is connected to one end of the temperature sensing package and the temperature control part 3 respectively. Among them, there is a switch in the power supply component 20, which controls whether the power supply component 20 and the first control part 4 and the power supply component and the socket component 21 are in a power-on state or a power-off state. Specifically, the switch has a closed state and an open state. When the switch is in a closed state, the switch controls the power supply component 20 and the first control part 4 and the power supply component and the socket component 21 to be in a power-on state, the power supply component 20 supplies power to the first control part 4 and the socket component 21, and the temperature sensing package and the temperature control part 3 are powered through the power supply component 20. When the switch is in an open state, the power supply component 20 and the first control part 4 and the power supply component and the socket component 21 are in a power-off state.

[0036] During actual operation, when the temperature sensing package is connected to the socket assembly 21 and the first control unit 4 respectively, a closed-loop circuit is formed between the power supply assembly 20 (when the switch of the power supply assembly 20 is in a closed state), the socket assembly 21, the temperature sensing package and the first control unit 4.

[0037] The experimental space 10 is a closed experimental space 10. Such a structural setting is adopted to ensure that the temperature sensing package in the experimental space 10 is not affected by the external environment temperature during the test process.

[0038] In the actual working process, the temperature sensing package is now placed in the experimental space 10, one end of the temperature sensing package is connected to the socket assembly 21 of the power supply unit 2, and the other end of the temperature sensing package is connected to the first control unit 4. When the connection is completed, when the switch in the power supply assembly 20 of the power supply unit 2 is in a closed state, the power supply assembly 20 of the power supply unit 2 supplies power to the socket assembly 21 of the power supply unit 2 and the first control unit 4. During the test process, the first control unit 4 controls the temperature control unit 3 to start, and the temperature control unit 3 raises the temperature in the experimental space 10 to a preset temperature. During the temperature rise process in the experimental space 10, the temperature control unit 3 collects the temperature in the experimental space 10 at regular intervals according to the signal sent by the first control unit 4. And the first control unit 4 will synchronously obtain the resistance value of the temperature sensing package at the temperature in the experimental space 10 collected by the temperature control unit 3, and determine whether the temperature sensing package will fail during the temperature rise process in the experimental space 10. When the temperature in the experimental space 10 reaches the preset temperature, the first control unit 4 obtains the resistance value of the temperature sensing package when the temperature in the experimental space 10 first reaches the preset temperature, and controls the temperature control unit 3 to maintain the temperature in the experimental space 10 at the preset temperature. The first control unit 4 sets a preset time and determines whether the temperature sensing package will fail at the preset temperature within the preset time.

[0039] In the actual working process, the staff will input the preset temperature and preset duration into the first control unit 4 in advance. And the staff will also input some instructions into the first control unit 4 in advance according to the actual situation, for example: when the temperature in the experimental space 10 is rising, how often does the first control unit 4 obtain the temperature in the experimental space and the resistance value of the temperature sensing package at the temperature; when the temperature in the experimental space 10 is maintained at the preset temperature, how often does the first control unit 4 obtain the resistance value of the temperature sensing package at the preset temperature within the preset duration; the first control unit 4 obtains the resistance value of the temperature sensing package when the temperature in the experimental space 10 first rises to the preset temperature.

[0040] During the actual working process, the preset temperature is set to 100°C, the preset time is 800H, and the first control unit 4 is set to obtain the temperature in the experimental space and the resistance value of the temperature sensing package at this temperature once every second; and the first control unit 4 obtains the resistance value of the temperature sensing package at the preset temperature once every second within the preset time.

[0041] In the actual working process, when the temperature in the experimental space 10 is rising, the temperature control unit 3 will collect the temperature in the experimental space 10 according to the acquisition requirement of the first control unit 4 .

[0042] In actual working process, the temperature control part 3 is a thermostat, which has the function of collecting the temperature in the experimental space 10 and heating. Alternatively, the temperature control part 3 includes a thermostat and a sensor, which are arranged on the inner wall of the experimental space 10 at intervals.

[0043] In actual operation, the temperature control unit 3 is connected to the first control unit 4 through the intermediate relay 13. The intermediate relay 13 is connected to the first terminal of the temperature control unit 3 and the power supply terminal of the socket assembly 21, respectively, and the second terminal of the temperature control unit 3 is connected to the ground terminal of the socket assembly 21, and the intermediate relay 13, the socket assembly 21 and the temperature control unit 3 form a closed circuit. At the same time, the temperature control unit 3 is connected to the first control unit 4 through the intermediate relay 13.

[0044] In the specific implementation process, Figure 6 As shown, the temperature sensing package test device also includes: a second control unit 5, the second control unit 5 is connected to the first control unit 4 by signal, and the first control unit 4 controls the operating state of the temperature control unit 3 according to the signal sent by the second control unit 5, whether to obtain the temperature in the experimental space 10 and the resistance value of the temperature sensing package, and whether to judge whether the temperature sensing package will fail during the temperature rise process and whether the temperature sensing package fails at a preset temperature within a preset time. With such a structural setting, the first control unit 4 can be controlled by the second control unit 5, and the temperature sensing package test device can stop testing the temperature sensing package in time when the temperature sensing package is found to be invalid during the test process through the second control unit 5 and the first control unit 4, thereby reducing the test cost and saving power.

[0045] The “temperature” in the above “determining whether the temperature sensing package will fail during the temperature rise process” refers to the temperature in the experimental space 10 .

[0046] In the specific implementation process, such as Figure 6As shown, the second control unit 5 includes a first operation button 51 and a first stop button 52. When the first operation button 51 is pressed, the first control unit 4 receives a signal, and the first control unit 4 controls the operation of the temperature control unit 3, obtains the temperature in the experimental space 10 and the resistance value of the temperature-sensing package, and starts to judge whether the temperature-sensing package will fail during the temperature rise process. When it is judged that the temperature-sensing package fails during the temperature rise process, the first control unit 4 sends a signal, the first stop button 52 is pressed, and the temperature-sensing package test device stops testing the temperature-sensing package. When it is judged that the temperature-sensing package has not failed during the temperature rise process, the temperature in the experimental space 10 will continue to rise, and it will continue to judge whether the temperature-sensing package fails during the temperature rise process until the temperature in the experimental space 10 rises to the preset temperature. When the temperature of the experimental space 10 reaches the preset temperature, within the preset time, the first control unit 4 judges whether the temperature-sensing package fails at the preset temperature. When it is judged that the temperature-sensing package fails at the preset temperature, the first control unit 4 sends a signal, the first stop button 52 is pressed, and the temperature-sensing package test device stops testing the temperature-sensing package. When it is determined that the temperature sensing package has not failed at the preset temperature, the first control unit 4 will continue to judge until the temperature in the experimental space 10 is maintained at the preset temperature for a preset period of time. When the temperature in the experimental space 10 is maintained at the preset temperature for a preset period of time, the first control unit 4 sends a signal, the first stop button 52 is pressed, and the temperature sensing package testing device ends the test on the temperature sensing package.

[0047] The specific process of the first control unit 4 controlling the operation of the temperature control unit 3 is as follows: when the first operation button 51 is pressed, the coil in the intermediate relay 13 is energized, and the temperature control unit 3 starts to operate. When the first stop button 52 is pressed, the coil in the intermediate relay 13 is disconnected, and the temperature control unit 3 stops operating.

[0048] In the specific implementation process, Figure 4 and Figure 5 As shown, a temperature sensing tank 100 for placing a temperature sensing package is provided on the experimental table 1; the temperature sensing package testing device also includes an insulating cover plate 6, which is provided on the experimental table 1, and at least a portion of the insulating cover plate 6 is used to seal the temperature sensing tank 100, and the temperature sensing tank 100 and at least a portion of the insulating cover plate 6 enclose an experimental space 10.

[0049] In the specific implementation process, Figures 6 to 9As shown, there are multiple temperature sensing tanks 100, and the multiple temperature sensing tanks 100 are arranged at intervals along the length direction of the experimental platform 1. The insulating cover plate 6 extends along the length direction of the experimental platform, and at least part of the insulating cover plate 6 is used to block the multiple temperature sensing tanks 100; there are multiple temperature control parts 3, and there are multiple second control parts 5. The multiple temperature control parts 3 and the multiple second control parts 5 are arranged one by one with the multiple temperature sensing tanks 100; the multiple temperature control parts 3 are all electrically connected to the power supply part 2, and the multiple temperature control parts 3 are all connected to the first control part 4 for communication; and the multiple second control parts 5 are all connected to the first control part 4 for signal. With such a result setting, by setting multiple temperature sensing tanks 100, it is possible to test multiple temperature sensing packages, thereby improving the test efficiency of the temperature sensing package testing device. At the same time, multiple second control parts 5 are set, so that during the test process, if at least one temperature sensing package among the multiple temperature sensing packages fails, the temperature sensing package testing device can stop testing each failed temperature sensing package separately through each second control part 5 corresponding to each failed temperature sensing package, so that the remaining temperature sensing packages that have not failed can continue to be tested. The test cost of the temperature sensing package test device is reduced.

[0050] In the actual working process, there is one first control unit 4, and one first control unit 4 is respectively connected to multiple second control units 5, multiple temperature sensing packages and multiple temperature control units 3. With such a structural setting, the temperature sensing packages in each temperature sensing tank can be tested synchronously and monitored independently through the first control unit 4, multiple second control units 5 and multiple temperature control units 3.

[0051] In actual operation, a temperature sensing package is placed in a temperature sensing tank 100. In addition, an insulating layer is provided in the temperature sensing tank 100 and a shielding setting is performed. With such a structural setting, the insulating layer has the effect of heat preservation and heat isolation, and the shielding setting is performed to prevent the temperature sensing packages in each temperature sensing tank 100 from interfering with each other during the test.

[0052] In the specific implementation process, Fig.10 As shown, the temperature sensing package test device also includes a terminal unit 7, which is connected to the first control unit 4 for communication, and is used to receive, store and display the temperature in the experimental space 10 and the resistance value of the temperature sensing package, as well as the percentage of the resistance change of the temperature sensing package, obtained by the first control unit 4. With such a structural setting, it is convenient for the staff to observe the changes of the temperature sensing package in the test process in real time, and it is convenient for the staff to find out in time when a fault occurs, so as to further achieve the purpose of real-time monitoring of the test process.

[0053] In the actual working process, the staff can also export the stored data through the terminal unit 7 so that the staff can further evaluate the performance of the temperature sensing package.

[0054] In the actual working process, each temperature-sensing package will have a material code, and the material code of each temperature-sensing package will also be displayed through the terminal part 7 so that the staff can distinguish each temperature-sensing package.

[0055] In the actual working process, the terminal part 7 is connected to the first control part 4 through the converter 14. The converter 14 is an RS485 / RS232 converter, and the converter 14 is used for data transmission communication.

[0056] In the specific implementation process, Figure 6 and Fig.10 As shown, the temperature sensing package test device also includes a plurality of indicating parts 8, which are arranged one by one with the plurality of temperature sensing tanks 100, and the plurality of indicating parts 8 are all connected to the first control part 4 for communication, and each indicating part 8 is activated according to the judgment result of the first control part 4 on the temperature sensing package placed in each temperature sensing tank 100 corresponding to each indicating part 8. Such a structural setting is adopted to facilitate giving a signal to the staff so that the staff can operate the second control part 5.

[0057] In the actual work process, Figure 6 and Fig.10 As shown, the indicator 8 includes a first indicator light 81 and a second indicator light 82. When the first control unit 4 determines that at least one of the multiple temperature-sensing packages is invalid, the first indicator lights 81 in the indicator parts 8 corresponding to the invalid temperature-sensing packages light up in red. The staff presses the first stop buttons 52 corresponding to the invalid temperature-sensing packages under the instruction of the first indicator lights 81, and the temperature-sensing package testing device stops testing the invalid temperature-sensing packages. When the test is completed, the second indicator lights 82 corresponding to the non-invalid temperature-sensing packages light up in green. The staff presses the first stop buttons 52 corresponding to the invalid temperature-sensing packages under the instruction of the second indicator lights 82, and the temperature-sensing package testing device ends the test on the invalid temperature-sensing packages.

[0058] In the specific implementation process, Fig.10 As shown, the temperature sensing package test device also includes a plurality of warning parts 9, which are arranged one by one with the plurality of temperature sensing tanks 100, and the plurality of warning parts 9 are all connected to the first control part 4 in communication. The first control part 4 controls whether each warning part 9 corresponding to each temperature sensing tank 100 is started according to the result of the first control part 4 judging whether the temperature sensing package placed in each temperature sensing tank 100 is invalid; wherein, when the first control part 4 judges that the temperature sensing package placed in at least one of the plurality of temperature sensing tanks 100 is invalid, the first control part 4 controls the warning part 9 corresponding to the temperature sensing tank 100 for placing the invalid temperature sensing package to start. With such a structural setting, it is convenient to judge whether the temperature sensing package is invalid during the test process, and further prompts can be given to the staff.

When the temperature sensing package is ready for testing, the other end of the first connecting line passes through the insulating cover plate 6 and is connected to the socket assembly 21, and the other end of the second connecting line is connected to the first control unit 4.

[0062] In actual operation, there are multiple positioning parts 11, and the multiple positioning parts 11 are arranged one by one with the multiple temperature sensing tanks 100. The multiple positioning parts 11 extend along the length direction of the experimental table 1. The socket assembly 21 extends along the length direction of the experimental table 1, and the socket assembly 21 is provided with multiple connection holes, which are arranged at intervals along the extension direction of the socket assembly 21, so that the first connection line of each temperature sensing package is connected to the socket assembly 21 through one of the multiple connection holes.

[0063] In the specific implementation process, Figure 4 As shown, the positioning portion 11 is provided with a wire clamping groove 110 adapted to the first connecting wire, and at least part of the first connecting wire is clamped in the wire clamping groove 110, and the first connecting wire is positioned by the wire clamping groove 110.

With such a structural arrangement, the insulating cover plate 6 is used to block the support groove 1030 and the temperature sensing tank 100, which can further improve the closedness of the experimental space 10 and prevent the temperature sensing package from being affected by the outside world during the test process.

[0064] In actual operation, the support groove 1030 extends along the height direction of the experimental table 1, one end of the support groove 1030 penetrates the step top surface 102, and the other end of the support groove 1030 is connected to the temperature sensing tank 100. There are multiple support grooves 1030, and the multiple support grooves 1030 are arranged at intervals along the length direction of the experimental table, and the multiple support grooves 1030 are arranged one by one with the multiple temperature sensing tanks 100. In addition, the length of the insulating cover plate 6 extends along the length of the experimental table, and the multiple support grooves 1030 and the multiple temperature sensing tanks 100 are blocked together by an insulating cover plate 6.

[0065] In actual working process, the structure of the insulating cover plate 6 is adapted to the step structure of the experimental platform 1 , so that the insulating cover plate 6 can seal the supporting groove 1030 and the temperature sensing groove 100 .

[0066] The insulating cover plate 6 includes a first insulating plate 61, a second insulating plate 62 and a third insulating plate 63. The side of the first insulating plate 61 is connected to the first side of the second insulating plate 62, and the second side of the second insulating plate 62 corresponding to the first side is connected to the side of the third insulating plate 63.

The insulating cover plate 6 forms a step structure compatible with the step structure of the experimental bench 1 through the first insulating plate 61, the second insulating plate 62 and the third insulating plate 63, so that the insulating cover plate 6 can block the multiple temperature sensing grooves 100 arranged on the bottom surface of the step and the multiple supporting grooves 1030 arranged on the side surface of the step.

[0067] In the specific implementation process, Figure 4 As shown, the temperature sensing package testing device also includes a mounting plate 12, which is protruding from the step top surface 102 and is spaced apart from the positioning portion 11; at least part of the power supply portion 2 and the second control portion 5 are spaced apart on one side of the mounting plate 12 close to the temperature sensing bath 100.

[0069] In the specific implementation process, Figure 4 As shown, the temperature sensing package testing device further includes a third control unit 15 , which is signal-connected to the first control unit 4 , and controls the operating state of the first control unit 4 .

[0070] In actual operation, the third control unit 15 includes a second operation button 151 and a second stop button 152. The second operation button 151 controls the operation of the first control unit 4. The second stop button 152 controls the first control unit 4 to stop operating.

[0071] Please refer to Figures 1 to 3 The utility model also provides a temperature-sensing package testing method, which includes: after receiving a test instruction from a test device, raising the temperature in an experimental space for placing the temperature-sensing package to a preset temperature, and judging whether the temperature-sensing package fails during the temperature rising process; if it is judged that the temperature-sensing package fails during the temperature rising process, the temperature-sensing package is deemed to be unqualified, and the test device stops testing the temperature-sensing package; if it is judged that the temperature-sensing package does not fail during the temperature rising process, maintaining the temperature in the experimental space at a preset temperature, and judging whether the temperature-sensing package fails at a preset temperature within a preset time; if it is judged that the temperature-sensing package fails at the preset temperature, the temperature-sensing package is deemed to be unqualified, and the test device stops testing the temperature-sensing package; if it is judged that the temperature-sensing package does not fail at the preset temperature, the temperature-sensing package is deemed to be qualified, and the test device ends testing the temperature-sensing package.

[0072] By adopting such a method, the temperature sensing package testing method provided by the utility model can automatically raise the temperature in the experimental space to the preset temperature after receiving the test instruction of the test device, and automatically judge whether the temperature sensing package will fail during the temperature rise process, and then when it is judged that the temperature sensing package fails during the temperature rise process, the test device can stop testing the temperature sensing package in time, thereby realizing that the state of the temperature sensing package can be monitored in real time during the temperature rise period in the experimental space; avoiding the problem of continuing to test when the temperature sensing package fails during the temperature rise process and cannot be found, saving the test cost and test time, and improving the reliability of the test results. At the same time, when the temperature in the experimental space is maintained at the preset temperature, it will continue to judge whether the temperature sensing package fails at the preset temperature within the preset time, and then when it is judged that the temperature sensing package fails at the preset temperature within the preset time, the test device can also stop testing the temperature sensing package in time, avoiding the waste of subsequent testing of the temperature sensing package that fails at the preset temperature. It is realized that when the temperature in the experimental space is maintained at the preset temperature, the state of the temperature sensing package can be monitored in real time within the preset time. It can be seen that the temperature sensing package test method can comprehensively evaluate the performance of the temperature sensing package by adopting multi-stage judgment, improve the comprehensiveness and accuracy of the test, and can also promptly detect failed temperature sensing packages, improve the efficiency of the test and reduce the test cost. The temperature sensing package test method realizes real-time monitoring of the status of the temperature sensing package during the test, which can effectively solve the technical problem in the prior art that it is impossible to monitor whether the temperature sensing package will fail during the test of the temperature sensing package.

[0073] Among them, the preset temperature is set by the staff, and the temperature in the placement space for the temperature-sensing package is raised to the preset temperature. The purpose is to simulate a high-temperature environment, test the actual use of the temperature-sensing package in a high-temperature environment, and verify the performance and stability of the temperature-sensing package under high-temperature conditions, so as to ensure the reliability and stability of the temperature-sensing package in actual applications. Usually, the preset temperature is set to 100°C. The "temperature rise process" in the above "determining whether the temperature-sensing package fails during the temperature rise process" refers to the process of gradually raising the temperature in the experimental space to the preset temperature; for example, the preset temperature is set to 100°C, and the temperature in the experimental space before the test is 0°C, then the "temperature rise process" is the process of the temperature in the experimental space rising from 0°C to 100°C.

[0074] The preset duration is also set by the staff according to the specific test requirements and the characteristics of the temperature package. The preset duration refers to the time the temperature in the experimental space is maintained at the preset temperature after reaching the preset temperature during the test. The purpose of setting the preset duration is to simulate a constant temperature environment. Within the preset duration, it is determined whether the temperature package will fail at the preset temperature for a long time, so as to evaluate the high temperature resistance of the temperature package. In the actual test process, the staff will set the preset duration to 800H.

[0075] Furthermore, a method for determining whether a temperature sensing package fails during a temperature rise process includes: obtaining the resistance of the temperature sensing package at a current temperature during a temperature rise process; comparing the resistance of the temperature sensing package at a current temperature with an ideal resistance of the temperature sensing package at a current temperature, and determining whether the temperature sensing package fails based on the comparison result of the resistance of the temperature sensing package at a current temperature with the ideal resistance of the temperature sensing package at a current temperature.

[0076] Among them, the ideal resistance value usually refers to the expected resistance value at a specific temperature calculated based on the design specifications and material properties of the temperature sensing package, as well as the working principle and characteristics of the temperature sensor. This ideal resistance value is used as a reference value to compare the actual measured resistance value of the temperature sensing package to evaluate the performance of the temperature sensing package at the current temperature. The "current temperature" in the above "obtaining the resistance value of the temperature sensing package at the current temperature during the temperature rising process" refers to the temperature in the current experimental space. The "resistance value of the temperature sensing package at the current temperature" in "obtaining the resistance value of the temperature sensing package at the current temperature during the temperature rising process" refers to the actual resistance value of the temperature sensing package at the temperature in the current experimental space.

[0077] In actual work, the ideal resistance value of the temperature-sensing package at different temperatures will be input into the test device in advance by the staff. During the test, the ideal resistance value of the temperature-sensing package at the current temperature will be retrieved according to the current temperature.

[0078] In the actual working process, when the temperature in the experimental space is rising, the test device will automatically obtain the temperature in the experimental space and the resistance value of the temperature-sensing package at the temperature in the current experimental space at intervals; then, the ideal resistance value of the temperature-sensing package at the temperature in the current experimental space will be retrieved according to the obtained temperature in the current experimental space, and the resistance value of the temperature-sensing package at the temperature in the current experimental space will be compared with the ideal resistance value of the temperature-sensing package at the temperature in the current experimental space. Finally, according to the comparison result, it is determined whether the temperature-sensing package has failed. If it is determined that the temperature-sensing package has not failed, the test device will repeat the above actions until the temperature in the experimental space rises to the preset temperature. Among them, the "time" in the above "the test device will automatically obtain the temperature in the experimental space and the resistance value of the temperature-sensing package at the temperature in the current experimental space at intervals" is set in advance by the staff according to the actual situation. Preferably, the test device is set to automatically collect the temperature in the experimental space and the resistance value of the temperature-sensing package at that temperature every second.

[0079] Furthermore, a method for determining whether the temperature sensing package has failed based on a comparison result of the resistance of the temperature sensing package at the current temperature with the ideal resistance of the temperature sensing package at the current temperature includes: obtaining a first change value, the first change value being the percentage of the absolute value of the change in the resistance of the temperature sensing package at the current temperature relative to the ideal resistance of the temperature sensing package at the current temperature; comparing the first change value with a first preset threshold, and determining whether the temperature sensing package has failed based on the comparison result of the first change value with the first preset threshold.

[0080] The first preset threshold refers to the percentage of the maximum change in the resistance of the temperature sensing package at the current temperature relative to the ideal resistance of the temperature sensing package at the current temperature set by the staff according to the actual situation. Preferably, the first preset threshold is set to 3%.

[0081] Furthermore, a method for determining whether the temperature sensing package has failed based on a comparison result between a first change value and a first preset threshold value includes: when the first change value is greater than the first preset threshold value, the temperature sensing package has failed; when the first change value is less than or equal to the first preset threshold value, the temperature sensing package has not failed.

[0082] Furthermore, the percentage of the absolute value of the change in the resistance of the temperature sensing package at the current temperature relative to the ideal resistance of the temperature sensing package at the current temperature is equal to the percentage of the ratio of the first resistance difference to the ideal resistance of the temperature sensing package at the current temperature; wherein the first resistance difference is the absolute value of the difference between the resistance of the temperature sensing package at the current temperature and the ideal resistance of the temperature sensing package at the current temperature.

[0083] Specifically, the calculation steps for the percentage of the absolute value of the change in the resistance of the temperature-sensing package at the current temperature relative to the ideal resistance of the temperature-sensing package at the current temperature are as follows:

[0084] First, the resistance value of the temperature sensing package at the current temperature is subtracted from the ideal resistance value of the temperature sensing package at the current temperature, thereby obtaining the difference between the resistance value of the temperature sensing package at the current temperature and the ideal resistance value of the temperature sensing package at the current temperature.

[0085] Then, take the absolute value of the difference, divide it by the ideal resistance of the temperature sensing package at the current temperature, and multiply it by 100%.

[0086] Finally, the percentage of the absolute value of the change in the resistance value of the temperature sensing package at the current temperature relative to the ideal resistance value of the temperature sensing package at the current temperature is obtained.

[0087] In the actual test process, the resistance of the temperature sensing package at the current temperature may be greater than the ideal resistance of the temperature sensing package at the current temperature, and the resistance of the temperature sensing package at the current temperature may be less than the ideal resistance of the temperature sensing package at the current temperature. Therefore, the percentage of the change in the resistance of the temperature sensing package at the current temperature relative to the ideal resistance of the temperature sensing package at the current temperature may be negative. Therefore, in order to facilitate comparison with the first preset threshold, the percentage of the absolute value of the change in the resistance of the temperature sensing package at the current temperature relative to the ideal resistance of the temperature sensing package at the current temperature is taken and compared with the first preset threshold.

[0088] like Figure 2 As shown in the figure, the actual test process for judging whether the temperature sensing package fails during the temperature rise (i.e., the temperature in the experimental space) is:

[0089] Step 1: When the temperature in the experimental space is rising, the testing device will obtain the temperature in the experimental space and the resistance value of the temperature-sensing package at the current temperature in the experimental space; then, the ideal resistance value of the temperature-sensing package at the current temperature in the experimental space will be retrieved according to the obtained temperature in the current experimental space.

[0090] Step 2: Calculate the first change value (i.e., the percentage of the absolute value of the change in the resistance of the temperature sensing package at the current temperature relative to the ideal resistance of the temperature sensing package at the current temperature) based on the resistance of the temperature sensing package at the current temperature in the experimental space and the ideal resistance of the temperature sensing package at the current temperature. Determine whether the temperature sensing package has failed based on the comparison result between the first change value and the first preset threshold. When the first change value is greater than the first preset threshold, the temperature sensing package fails, the temperature sensing package is deemed unqualified, and the test device stops testing the temperature sensing package; when the first change value is less than or equal to the first preset threshold, the temperature sensing package has not failed.

[0091] Step three, when the temperature sensing package has not failed, the test device will repeat steps one and two while the temperature in the experimental space is rising to the preset temperature (i.e., the temperature in the experimental space is rising) until the temperature in the experimental space reaches the preset temperature.

[0092] Furthermore, a method for determining whether a temperature sensing package fails at a preset temperature within a preset time period includes: obtaining the resistance of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature; obtaining the resistance of the temperature sensing package at a preset temperature within a preset time period; comparing the resistance of the temperature sensing package at the preset temperature with the resistance of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature, and determining whether the temperature sensing package fails based on the comparison result of the resistance of the temperature sensing package at the preset temperature with the resistance of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature.

[0093] During the actual test process, when the temperature in the experimental space is maintained at a preset temperature, the resistance value of the temperature-sensing package at the preset temperature is automatically obtained once every time within a preset time, and then the resistance value of the temperature-sensing package at the preset temperature is compared with the resistance value of the temperature-sensing package when the temperature in the experimental space first rises to the preset temperature. Finally, based on the comparison result, it is determined whether the temperature-sensing package has failed. If it is determined that the temperature-sensing package has not failed, the test device will repeat the above actions until the temperature in the experimental space is maintained at the preset temperature for a preset time. Among them, the "time" in the above "automatically obtaining the resistance value of the temperature-sensing package at the preset temperature every time within a preset time" is set in advance by the staff according to actual conditions. Preferably, the test device is set to automatically collect the resistance value of the temperature-sensing package at the preset temperature once every second.

[0094] Furthermore, a method for determining whether the temperature sensing package has failed based on a comparison result of a resistance value of the temperature sensing package at a preset temperature with a resistance value of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature includes: obtaining a second change value, where the second change value is a percentage of an absolute value of a change in the resistance value of the temperature sensing package at a preset temperature relative to the resistance value of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature; comparing the second change value with a second preset threshold value, and determining whether the temperature sensing package will fail based on a comparison result of the second change value with the second preset threshold value.

[0095] The second preset threshold refers to the percentage of the maximum change in the resistance of the temperature-sensing package at the preset temperature relative to the resistance of the temperature-sensing package when the temperature in the experimental space first rises to the preset temperature, which is set by the staff according to actual conditions. Preferably, the second preset threshold is set to 3%.

[0096] Furthermore, a method for determining whether the temperature sensing package has failed based on a comparison result between the second change value and the second preset threshold value includes: when the second change value is greater than the second preset threshold value, the temperature sensing package has failed; when the second change value is less than or equal to the second preset threshold value, the temperature sensing package has not failed.

[0097] Furthermore, the percentage of the absolute value of the change in the resistance of the temperature sensing package at the preset temperature relative to the resistance of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature is equal to the percentage of the ratio of the second resistance difference to the resistance of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature; wherein the second resistance difference is the absolute value of the difference between the resistance of the temperature sensing package at the preset temperature and the resistance of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature.

[0098] Specifically, the calculation steps for the percentage of the absolute value of the change in the resistance of the temperature-sensing package at the preset temperature relative to the resistance of the temperature-sensing package when the temperature in the experimental space first rises to the preset temperature are as follows:

[0099] First, the resistance value of the temperature sensing package at the preset temperature is subtracted from the resistance value of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature, thereby obtaining the difference between the resistance value of the temperature sensing package at the preset temperature and the resistance value of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature.

[0100] Then, take the absolute value of the difference, divide it by the resistance value of the temperature sensing package when the temperature in the experimental space rises to the preset temperature for the first time, and then multiply it by 100%.

[0101] Finally, the percentage of the absolute value of the change in the resistance of the temperature sensing package at the preset temperature relative to the resistance of the temperature sensing package when the temperature in the experimental space first rises to the preset temperature is obtained.

[0102] In the actual test process, the resistance of the temperature-sensing package at the preset temperature may be greater than the resistance of the temperature-sensing package when the temperature in the experimental space first rises to the preset temperature, and the resistance of the temperature-sensing package at the preset temperature may also be less than the resistance of the temperature-sensing package when the temperature in the experimental space first rises to the preset temperature. Therefore, the percentage of the resistance of the temperature-sensing package at the preset temperature relative to the resistance of the temperature-sensing package when the temperature in the experimental space first rises to the preset temperature may be negative. Therefore, in order to facilitate comparison with the second preset threshold, the percentage of the absolute value of the change in the resistance of the temperature-sensing package at the preset temperature relative to the resistance of the temperature-sensing package when the temperature in the experimental space first rises to the preset temperature will be taken and compared with the second preset threshold.

[0103] like Figure 3 As shown in the figure, the actual test process of judging whether the temperature sensing package fails at the preset temperature within the preset time is:

[0104] Step 1: Obtain the resistance value of the temperature sensing package when the temperature in the experimental space rises to the preset temperature for the first time.

[0105] Step 2: When the temperature in the experimental space is maintained at a preset temperature, the resistance value of the temperature sensing package at the preset temperature is obtained within a preset time.

[0106] Step three, according to the resistance value of the temperature-sensing package when the temperature in the experimental space rises to the preset temperature for the first time and the resistance value of the temperature-sensing package at the preset temperature obtained within the preset time, calculate the second change value, and compare the second change value with the second preset threshold. And according to the comparison result of the second change value and the second preset threshold, determine whether the temperature-sensing package has failed. When the second change value is greater than the second preset threshold, the temperature-sensing package fails, the temperature-sensing package is considered unqualified, and the test device stops testing the temperature-sensing package. When the second change value is less than or equal to the second preset threshold, the temperature-sensing package has not failed.

[0107] Step 4: When the temperature-sensing package has not failed, the test device will repeat steps 2 and 3 within the preset time, until the temperature in the experimental space is maintained at the preset temperature for a preset time. When the temperature in the experimental space is maintained at the preset temperature for a preset time, the change in the resistance value of the temperature-sensing package at the preset temperature is always less than or equal to the second preset threshold value, the temperature-sensing package is considered qualified, and the test device ends the test on the temperature-sensing package.

[0108] The utility model provides a temperature sensing package testing device, which is used for performing a heating test on the temperature sensing package. The temperature sensing package testing device comprises: a test bench 1, a power supply unit 2, a temperature control unit 3 and a first control unit 4. The test bench 1 is provided with a test space 10 for placing the temperature sensing package; the power supply unit 2 is connected to one end of the temperature sensing package; the temperature control unit 3 is arranged on the inner wall of the test space 10, and is used for raising the temperature in the test space 10 to a preset temperature and collecting the temperature in the test space 10; the temperature control unit 3 is electrically connected to the power supply unit 2; the first control unit 4 is electrically connected to the power supply unit 2, the other end of the temperature sensing package away from the power supply unit 2 is connected to the first control unit 4, and the first control unit 4 is communicatively connected to the temperature control unit 3, the first control unit 4 is used for controlling the operating state of the temperature control unit 3, for obtaining the temperature in the test space 10 and the resistance value of the temperature sensing package, for judging whether the temperature sensing package will fail during the temperature rising process, and for judging whether the temperature sensing package fails at a preset temperature within a preset time.

[0109] It can be seen that the temperature sensing package testing device provided by the utility model is simply arranged with a test bench 1, a power supply unit 2, a temperature control unit 3 and a first control unit 4. The test bench 1 is provided with a test space 10 for placing the temperature sensing package. The temperature control unit 3 is arranged on the inner wall of the test space 10. The first control unit 4 is communicated with the temperature control unit 3. The first control unit 4 is respectively connected to the power supply unit 2 and the other end of the temperature sensing package away from the power supply unit 2, so as to control the temperature control unit 3 through the first control unit 4. In addition, the first control unit 4 can also obtain the temperature in the test space 10 and the resistance value of the temperature sensing package, and judge whether the temperature sensing package will fail during the temperature rising process and judge whether the temperature sensing package fails at a preset temperature within a preset time. Thus, the temperature sensing package test device realizes, through the first control unit 4, that during the test process, the temperature sensing package test device monitors the state of the temperature sensing package placed in the experimental space in real time, thereby avoiding the problem that the temperature sensing package fails at a preset temperature during the heating process or within a preset time period and the test continues without being discovered, thereby reducing the test cost and saving the test time. At the same time, through the real-time monitoring of the temperature sensing package test device, the performance of the temperature sensing package can be comprehensively evaluated, the reliability and accuracy of the temperature sensing package test device can be improved, and the test efficiency of the temperature sensing package test device can be improved. The temperature sensing package test device has a simple structure and is easy to operate. It realizes real-time monitoring of the state of the temperature sensing package in the middle of the test, and can effectively solve the technical problem in the prior art that it is impossible to monitor whether the temperature sensing package will fail during the test of the temperature sensing package.
