[0043] 1. The keystroke monitoring module is used to detect the user's tapping behavior. The tapping behavior is divided into valid tapping and invalid tapping according to the continuous tapping of the input key. No tapping detection is performed for the fragmented tapping behavior of invalid tapping. The tapping detection of the back key is performed for the tapping behavior consisting of continuous tapping. Thus, the keystroke error rate in the valid tapping is determined by the tapping frequency of the back key. The sensitivity of the keyboard keys is fed back by the tapping error rate of the back key, without the need to perform press detection on each key of the folding keyboard, thereby reducing the sensitivity detection cost and improving the detection efficiency.

[0044] 2. The folding performance of the folding keyboard is tested through the folding analysis module, and the folding coefficient of the folding keyboard is obtained by analyzing the time and noise of the folding and unfolding of the folding key. The folding performance of the folding keyboard is fed back through the folding coefficient. The parameters of the folding and unfolding process of the folding keyboard are collected and comprehensively analyzed respectively, so that the result of the folding detection is more accurate;

[0045] 3. The comprehensive analysis module combines the retreat performance value, folding coefficient and failure coefficient to obtain the performance coefficient. The overall performance of the folding keyboard is fed back through the performance coefficient. The display module displays the performance coefficient and performance level in real time. The user can obtain the performance status of the folding keyboard in real time through the display module. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] If the interval between the next key being tapped and the last key being tapped is greater than one second, the tapping behavior is considered terminated, and the next tapping behavior begins when the input key is tapped. If the interval is too long, the tapping behavior is directly considered terminated.

[0053] If the interval between the next key being tapped and the last key being tapped is less than or equal to one second, it means that the tapping behavior is continuous, and the key type is analyzed:

[0054] If the next key tapped is the input key, the continuous tapping behavior is determined to be a typing behavior, then the tapping behavior is determined to continue, and the tapping count is increased by one;

[0055] If the next key tapped is a non-input key, it is determined that the continuous tapping behavior does not belong to the typing behavior, and the tapping behavior is terminated, and the next tapping behavior begins when the input key is tapped next time;

[0056] The tapping behavior with a number of tapping times less than L1 is marked as invalid tapping, and the tapping behavior with a number of tapping times not less than L1 is marked as valid tapping. When the number of valid tapping times reaches n, the valid tapping is backed off, and n, L1 and L2 are all quantitative constants;

[0057] The back-off detection process includes: marking the effective tapping as i, i=1, 2, ..., n, n is a positive integer, marking the number of tapping of the effective tapping i as QJi, analyzing the tapping situation of the back key in the effective tapping i: when the back key is tapped, the number of tapping of the back key is increased by one, when the back key is tapped continuously, the tapping behavior belongs to continuous back-off, and the number of tapping of the back key remains unchanged; marking the number of tapping of the back key as HTi; marking the ratio of HTi to QJi as the back-off rate HLi of the effective tapping i, the back-off rate is a value reflecting the error rate of the tapping behavior, the higher the value of the back-off rate is, the higher the error rate of the tapping behavior is, and the worse the sensitivity of the keyboard keys is; summing and averaging the back-off rates of the effective tapping i to obtain the back-off performance value HZ of the effective tapping, and comparing the back-off performance value HZ of the effective tapping with the back-off thresholds HZmin and HZmax:

[0058] If HZ≤HZmin, the key sensitivity level of the keyboard is determined to be level one;

[0059] If HZmin<HZ<HZmax, the key sensitivity level of the keyboard is determined to be level 2;

[0060] If HZ≥HZmax, the keyboard key sensitivity level is determined to be level three;

[0061] The key monitoring module sends the keyboard key sensitivity level and back performance value to the comprehensive analysis module through the monitoring platform.

The time performance value SJ is a value reflecting the smoothness of folding and unfolding of the folding keyboard. The smaller the value of the time performance value, the smoother the folding and unfolding of the folding keyboard. α1 and α2 are both proportional coefficients, and α1>α2>1;

[0064] The maximum noise decibel value during the keyboard folding process is marked as folding noise, and the maximum noise decibel value during the keyboard unfolding process is marked as unfolding noise. The folding noise and the unfolding noise are summed and averaged to obtain the noise performance value ZS;

[0065] The folding coefficient ZX of the folding keyboard is obtained by the formula ZX=u×(β1×SJ+β2×ZS). The folding coefficient is a value that reflects the folding performance of the folding keyboard. The larger the value of the folding coefficient, the worse the folding performance of the folding keyboard. β1 and β2 are both proportional coefficients, and β1>β2>1. u is a correction factor, and the value of u is 2.23.

[0066] Compare the folding coefficient ZX of the folding keyboard with the folding thresholds ZXmin and ZXmax:

[0067] If ZX≤ZXmin, the folding level of the folding keyboard is determined to be level one;

The fault coefficient GX is a value reflecting the fault frequency of the folding keyboard. The larger the value of the fault coefficient, the higher the fault frequency of the folding keyboard, wherein θ1 and θ2 are both proportional coefficients, and θ1>θ2>1; the fault analysis module sends the fault coefficient GX of the folding keyboard to the comprehensive analysis module through the monitoring platform;

[0072] The comprehensive analysis module is used to analyze the overall performance of the folding keyboard: if the key sensitivity level or folding level of the folding keyboard is level three, the performance test result of the folding keyboard is judged as unqualified; if the key sensitivity level and folding level of the folding keyboard are not level three, the performance level of the folding keyboard is analyzed: through the formula The performance coefficient XN of the folding keyboard is obtained. The performance coefficient is a value that reflects the overall performance of the folding keyboard. The lower the value of the performance coefficient, the better the overall performance of the folding keyboard. γ1, γ2 and γ3 are all proportional coefficients, and γ1>γ2>γ3>1; the performance coefficient XN of the folding keyboard is compared with the performance thresholds XNmin and XNmax:

[0073] If XN≤XNmin, the performance level of the folding keyboard is determined to be level one;
