[0025] The following disclosure provides many different implementation manners or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model.

[0026] Specifically, as Figure 1 shown, it is a schematic structural diagram of an embodiment of a performance detection system provided by an embodiment of the present application. InFigure 1 Among them, the performance detection tooling includes a control host 10 and a performance detection device 20; among them, the control host 10 is mainly used to control the performance detection device to detect the performance of the ventilation equipment, and the performance detection device 20 is the main device to realize the detection function. In Figure 1 Among them, a host interface is provided in the control host 10, and the control host 10 is connected to the performance detection device 20 through its own host interface. The performance detection device includes a plurality of detection partitions, and a temperature detection slave 30 is provided in each detection partition, and a plurality of temperature detection slaves 30 are cascaded. A temperature measurement interface is provided in each temperature detection slave 30 for detecting the temperature at different positions of the ventilation equipment.

[0027] In an actual performance detection scenario, the performance detection tooling of the ventilation equipment further includes a housing, mainly the performance detection device 20 includes an external housing and the temperature detection slaves 30 provided inside the housing. Specifically, the performance detection device includes a housing, and the housing is assembled to form a plurality of detection partitions, and a temperature detection slave 30 is provided in each temperature detection partition, so as to directly detect the temperature at different positions or different regions by using different temperature detection slaves, and avoid affecting the test efficiency and test accuracy by replacing the test points. In the embodiment of the present invention, the housing can be a spliced housing or a foldable housing, so as to splice to form a plurality of detection partitions or fold the housing to form a plurality of detection partitions. In a specific embodiment, the housing can be spliced in nine pieces or folded in three sections to form 3×3 detection partitions, and temperature detection slaves are respectively provided in the nine detection partitions to detect the temperature at different positions or regions. In some embodiments, the housing can be made of acrylic board or plywood, or other materials, which is not limited here.

[0028] Such as Figure 2 shown, it is an unfolded schematic diagram of the detection partition provided by the embodiment of the present invention. In Figure 2 Among them, the nine detection partitions are folded to form a performance detection device; a plurality of detection points can also be provided in each detection partition, such as 3×5 detection points. In the embodiment of the present invention, the performance detection device 20 is a cuboid structure as a whole, and the cuboid structure includes 3×3 detection partitions, and the 3×3 detection partitions are stacked in the housing. Taking Figure 2 the embodiment shown as an example, the first detection partition, the second detection partition and the third detection partition are on the same layer, the fourth detection partition, the fifth detection partition and the sixth detection partition are on the same layer, and the seventh detection partition, the eighth detection partition and the ninth detection partition are on the same layer.

[0029] In the embodiment of the present utility model, the upper surface housing of the performance detection device can be a detachable structure for installing the temperature detection slave 30. At the same time, in some embodiments, when the housing is in a spliced state or a folded and unfolded state, the housing can be locked to prevent the housing from shaking and affecting the safety of the overall structure. In an actual performance detection device, openings can also be provided on the housing for wire routing; for example, multiple temperature detection slaves 30 are cascaded through the openings on the housing. Handles can also be provided on the upper and lower surfaces and / or the left and right surfaces of the housing to move the housing after folding the housing or to move the housing through the handles after the housing is unfolded. Pulleys can also be provided on the lower surface of the housing to improve the portability of the performance detection device. In other embodiments, the upper surface housing of the performance detection device can be made of transparent plywood to observe the internal operation of the performance detection device; while the other surface housings of the performance detection device can be made of acrylic plates.

[0030] Please refer to Figure 1 , the control host 10 is usually separately encapsulated, while multiple temperature detection slaves 30 are encapsulated in the housing of the performance detection device 20. Multiple host interfaces can be provided in the control host 10, including but not limited to a temperature control accuracy measurement interface 101 and a first host communication interface 102; among them, the first host communication interface 102 is connected to the performance detection device 20 for communication. In a specific embodiment, the first host communication interface 102 can be an RS485 communication interface using a standard communication protocol. The temperature control accuracy measurement interface 101 is mainly used to connect an external temperature probe to detect the ambient temperature; by detecting the ambient temperature and comparing it with the ambient temperature detected by other devices, it is determined whether the temperature detection accuracy of the control host is normal. In other embodiments, the control host can also include a contact maximum temperature sensor interface 103, and the contact maximum temperature sensor interface can detect the temperatures at different positions on the ventilation device to determine the maximum temperature on the ventilation device. It should be noted that the contact maximum temperature sensor interface can also be externally connected to a temperature probe, and the temperature probe can be moved on the ventilation device to detect the temperatures at different positions. The temperature measurement interfaces in the temperature detection slaves usually cannot be moved, but since a temperature detection slave usually includes multiple temperature measurement interfaces, the temperatures at different positions on the ventilation device can be detected simultaneously without moving the temperature detection slave, ensuring the consistency and detection efficiency during temperature detection.

[0031] For the performance detection device 20, the performance detection device 20 includes a plurality of cascaded temperature detection slaves 30 in sequence; in some embodiments, only one target temperature detection slave in the plurality of temperature detection slaves 30 needs to be connected to the control host 10, that is, connected to the first host communication interface 102 of the control host 10, so as to reduce the number of interfaces in the control host and reduce the number of wiring. Therefore, in the embodiments of the present invention, a slave communication interface 301 is also provided in each temperature detection slave 30, and the first host communication interface 102 is physically connected to the slave communication interface in the target temperature detection slave, but the first host communication interface 102 can communicate with multiple host communication interfaces at the same time. In order to implement the temperature detection function, each temperature detection slave 30 further includes a temperature sensor interface 302, that is, a temperature measurement interface; a temperature sensor is provided at a position corresponding to the temperature sensor interface 302 inside the temperature detection slave 30, and the temperature sensor in the temperature sensor interface 302 is used for temperature detection. In a specific embodiment, the temperature sensor may include a substrate and a thermistor. The substrate may be a copper substrate of 130mm * 130mm * 0.5mm, and the thermistor is encapsulated at the center of the substrate to collect temperature changes. At the same time, a 1x2 two-pin socket needs to be placed in the center area of the sensor for wiring.

[0032] In the embodiments of the present invention, there may be multiple temperature sensor interfaces 302 in one temperature detection slave 30, respectively corresponding to Figure 2 multiple detection sites in. For example, 15 temperature sensor interfaces arranged in an array are included at the same time, and the corresponding temperature sensors are also 15. One temperature sensor interface corresponds to one temperature sensor. Multiple temperature sensors can detect the temperatures of multiple positions or multiple regions at the same time, without moving the detection sites anymore, ensuring the efficiency and accuracy of temperature detection. In other embodiments, the number of temperature sensor interfaces and the spacing between different temperature sensors can be set according to actual needs, and are not limited in the present invention. At the same time, in the embodiments of the present invention, the structures of the temperature sensors in different temperature detection slaves 30 may be the same.

[0033] In the embodiment of the present utility model, the control host 10 further includes an alternating current interface to receive external power supply. The control host 10 also includes a switching power supply connected to the alternating current interface, and the other end of the switching power supply is connected to an AC-DC conversion chip (DCDC chip); the AC-DC conversion chip is also connected to the power supply system inside the control host 10, and this power supply system mainly supplies power to the communication interface, temperature control accuracy measurement interface 101, and maximum contact temperature sensor interface 102 inside the control host 10. It should be noted that in the present utility model, the control host communicates with the temperature detection slave 30 through the first host communication interface 102, and a second host communication interface is also provided inside the control host 10, and it communicates with an external display device through the second host communication interface. In a specific embodiment, the first host communication interface 102 can be an RS485 communication interface, and the second host communication interface can be an RS232 communication interface. For the temperature detection slave 30, any two cascaded temperature detection slaves 30 are also connected and communicate through their own slave communication interfaces; in a specific embodiment, the slave communication interface can also be an RS485 communication interface.

[0034] The embodiment of the present utility model also provides a performance detection system for a ventilation device, including the performance detection tooling for the ventilation device as described in any one of the previous items, and further including a display device; the display device is connected to the performance detection tooling for the ventilation device to display the performance data detected by the performance detection tooling, such as temperature data.

[0035] In an actual performance detection scenario, the user can select the temperature detection slave 30 on the control host 10 and generate a corresponding operation instruction, and the control host 10 sends the operation instruction to the performance detection device; since there are multiple temperature detection slaves 30 in the performance detection device, it is also necessary to select the required temperature detection slave from the multiple temperature detection slaves 30 according to the operation instruction. The selected temperature detection slave 30 analyzes the operation instruction to determine the model of the device to be detected and the specific acquisition and test points where the temperature needs to be measured; at the same time, the temperature detection slave 30 will collect the temperature using its own multiple temperature sensors, and after filtering and averaging the collected multiple temperatures, it will send them to the control host 10. The control host 10 will receive the average surface temperature of the device to be detected, or the temperature of a single acquisition and test point; and the temperature obtained by the control host 10 will be displayed on the display device. It should be noted that when actually performing performance detection, it is first necessary to use the temperature control sensor interface on the control host 10 to determine whether the temperature control accuracy is normal. If it is normal, subsequent temperature detection can be carried out; if the accuracy is abnormal, the temperature test accuracy of the control host needs to be adjusted.
