[0002] With the advancement of seat comfort system technology, seats with air exchange function have become a new type of product that is gradually accepted by people. Car seat ventilation means that a small fan is installed in the seat cushion and backrest to absorb the air flow in the cabin and guide it to the upper layer of the seat through a pipe, and then flow out through the air holes on the surface of the seat to form a ventilation effect. This design can effectively improve the air circulation environment of the part where the human body contacts the seat, prevent sweat accumulation on the buttocks and back, and provide a comfortable riding experience. The seat ventilation function is mainly divided into two types: blowing type and suction type; At present, the ventilation and massage testing of seats in the seat industry relies entirely on the sensory evaluation of ventilation and massage functions by personnel, which cannot be quantified and has a high risk of quality inspection. Therefore, it is necessary to use equipment to quantify ventilation and massage data, establish standards, realize automated testing, and improve quality standards. In view of the above technical problems, this application proposes a solution. Summary of the invention

[0013] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0014] Figure 1 is a system block diagram of the present invention; Figure 2 It is a system flow chart of the present invention. DETAILED DESCRIPTION

[0015] The technical scheme of the present invention will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0016] See also Figure 1 - Figure 2As shown, a flexible fully automatic detection system for ventilation and massage of automobile seats includes a ventilation detection module, a massage detection module, a cycle control unit, a result entry unit and a production line control unit. The production line control unit is used to control the double-speed chain body in the seat detection production line, and control the double-speed chain body to operate by generating a loading instruction or a unloading instruction, unloading the detected seats from the detection station, and moving the seats to be detected to the position of the detection station; The ventilation detection module includes an air volume control module, an air volume detection module and an analysis and generation module; The air volume control module is used to control the operation of the air outlet component under the seat so that the component can discharge air according to different air outlet parameters. The air outlet parameters include air volume and wind speed. The air volume control module changes the air volume and wind speed multiple times during the detection process, and records the air outlet parameters corresponding to each moment, and generates an image of the change of the air outlet parameters over time according to the time and the air outlet parameters; The air volume detection module detects the ventilation parameters above the seat, which also include air volume and wind speed. When detecting the ventilation parameters, the air volume detection module records the time synchronously, and draws a coordinate system with time as the horizontal axis and wind speed and air volume as the vertical axis, respectively, to obtain an image of the ventilation parameters changing with time; The analysis and generation module selects the point where the air volume changes in the image of the air output parameters changing with time, and records the time corresponding to the point where the air volume changes as the air volume input point, and selects the point where the wind speed changes, and records the time corresponding to the point where the wind speed changes as the wind speed input point; The analysis and generation module counts the number of air volume input points and wind speed input points to obtain the total number of input adjustments; The analysis and generation module obtains the point where the air volume changes in the image of the ventilation parameters changing with time, and records the corresponding time as the air volume output point, and the point where the wind speed changes, and records the corresponding time as the wind speed output point. The analysis and generation module records the sum of the number of the air volume output points and the wind speed output points as the ventilation change point; When the analysis and generation module obtains the point where the ventilation parameters change, the judgment method used is: In the image of ventilation parameter changes over time, the change speed of the ventilation parameter is calculated to obtain the air volume change speed and the wind speed change speed, and the air volume change speed is compared with the corresponding threshold value, the air volume change speed less than the threshold value is ignored, and the air volume change speed greater than or equal to the threshold value is recorded as the ventilation parameter change, and the wind speed change speed is compared with the corresponding threshold value, the air volume change speed less than the threshold value is ignored, and the air volume change speed greater than or equal to the threshold value is recorded as the ventilation parameter change; The analysis and generation module compares the ventilation change points with the total number of input adjustments. If the number of ventilation change points is the same as the total number of input adjustments, a change coupling signal is generated. If the number of ventilation change points is different from the total number of input adjustments, a change difference signal is generated and sent to the result entry unit through the network. After obtaining the change difference signal, the result entry unit generates a ventilation detection unqualified signal. After generating the variable coupling signal, the analysis and generation module numbers all the air volume input points in chronological order, and at the same time, numbers all the wind speed input points, air volume output points, and wind speed output points in chronological order. The analysis and generation module calculates the time difference between each group of air volume input points and air volume output points with the same number, and obtains multiple groups of air volume time lag values. Similarly, the analysis and generation module calculates the time difference between each group of wind speed input points and wind speed output points with the same number, and obtains multiple groups of wind speed time lag values. The analysis and generation unit performs arithmetic averaging on the air volume time lag values ​​to obtain the air volume time lag mean value, performs arithmetic averaging on the wind speed time lag values ​​to obtain the wind speed time lag mean value, and the analysis and generation unit compares the air volume time lag mean value and the wind speed time lag mean value with the corresponding standard upper limits respectively, and generates an abnormal air volume response signal if the air volume time lag mean value exceeds the corresponding standard upper limit, and generates a normal air volume response signal if the air volume time lag mean value does not exceed the corresponding standard upper limit, and generates an abnormal wind speed response signal if the wind speed time lag mean value exceeds the corresponding standard upper limit, and generates a normal wind speed response signal if the wind speed time lag mean value does not exceed the corresponding standard upper limit; When the analysis and generation unit sends the normal wind speed response signal, the normal wind volume response signal, the abnormal wind speed response signal and the abnormal wind volume response signal to the result entry unit, the result entry unit generates a ventilation detection qualified signal when it obtains the normal wind speed response signal and the normal wind volume response signal at the same time, and generates a ventilation detection unqualified signal when it obtains any one of the abnormal wind speed response signal and the abnormal wind volume response signal. Example

[0017] See also Figure 1 - Figure 2 As shown, the massage detection module includes a monitoring and capturing module and a point analysis module. The massage detection module can control the massage component of the car seat, so that the massage component enters the working state and switches between a variety of different massage control logics. The monitoring and capturing module can detect the seat surface through a contact pressure sensor to obtain the massage pressure and massage frequency transmitted by the massage component. The monitoring and capturing module sends the massage pressure and the massage frequency to the point analysis module, which compares the massage pressure and the massage frequency with the set massage pressure and the massage frequency. If the massage pressure meets the set massage pressure, a normal pressure regulation signal is generated; if the massage pressure does not meet the set massage pressure, a pressure regulation abnormality signal is generated; if the massage frequency meets the set massage frequency, a normal frequency regulation signal is generated; if the massage frequency does not meet the set massage frequency, a frequency regulation abnormality signal is generated; The massage detection module sends the frequency regulation abnormality signal, the pressure regulation abnormality signal, the pressure regulation normal signal, and the frequency regulation normal signal to the result entry unit; The result entry unit generates a massage detection qualified signal after simultaneously acquiring the pressure regulation normal signal and the frequency regulation normal signal, and generates a massage detection unqualified signal when acquiring any one of the frequency regulation abnormal signal and the pressure regulation abnormal signal. Example

[0018] See also Figure 1 - Figure 2 As shown, when the result entry unit generates a massage detection qualified signal and a ventilation detection qualified signal at the same time, it sends a detection completion instruction to the production line control unit; When the result input unit generates a massage detection failure signal or a ventilation detection failure signal, it sends a re-inspection instruction to the circulation control unit and marks the currently detected car seat. The circulation control unit sends a detection instruction to the ventilation detection module and the massage detection module again, so that the ventilation detection module and the massage detection module detect the marked car seat again. When the result entry unit obtains a massage test failure signal or a ventilation test failure signal for the marked car seat again, it sends a test completion instruction to the production line control unit, records the car seat as an unqualified seat, and sends the recorded seat number to the management platform via the network.
