Example 4

[0057] In order to enable the incontinence pad 1 to be installed on the patient's bed, generally, a port for convenient excretion is provided at the buttocks of a paralyzed patient on a bed, so two clamping plates 7 are provided to install the incontinence pad there;

[0058] refer to Figure 3 and 7 As shown, both the front and rear sides of the base 102 are provided with a slide groove 10203, and the bottom of the base 102 is provided with a slide groove 2 10204. The lower end of the base 102 is provided with two card plates 7, which are placed on both sides. The upper ends of the card plates 7 are provided with sliders 4 701 for moving in the slide groove 2 10204. Both sides of the card seat 103 are provided with card grooves 10301 for providing space for the card plates 7 to move. The card plates 7 use the gap between the base 102 and the base 102 to clamp the edge of the excretion port, which can stabilize the incontinence pad 1.

[0059] Specifically, two grooves 10205 are provided in the base 102 to provide a movable space for the slider 5 702 controlling the movement of the card plate 7. The upper end of the slider 4 701 is provided with a slider 5 702 through the slide groove 2 10204 and the groove 10205.

A limiting sleeve 9 corresponding to the straight rod 2 703 is provided on one side of the inner wall of the groove 10205. A spring 3 8 is provided between the limiting sleeve 9 and the slider 5 702. The card plate 7 moves in the groove 1 10205 based on the slider 5 702. The spring 3 8, the straight rod 2 703 and the limiting sleeve 9 form a buffer and limit function to ensure that the card plate 7 adjusts its position along the slide groove 1 10203 without being affected by the pressing block 6.

[0060] In addition, a slider 1 601 is provided at the rear end of the push block 6 for moving in the slide groove 10203, a slider 2 602 is provided at the rear end of the slider 1 601 through the groove 1 10205, a spring 2 603 is provided between one side of the slider 2 602 and the groove 1 10205, a straight rod 1 604 is provided on the other side of the slider 2 602, and a slider 3 605 is provided at the lower end of the straight rod 1 604.

As shown in the figure, the arcs at both ends of the rocking plate 10 are arranged in opposite directions. Therefore, when the straight rod 1 604 pushes one side of the rocking plate 10, the rocking plate 10 rotates the other side in the opposite direction under the action of the rotating rod 2 1001, and contacts the two ends of the slider 5 702 to make it approach the limit sleeve 9 under the push of the rocking plate 10, and makes the clamping plate 7 move inward along the slide groove 2 10204 under the action of the slider 4 701, thereby facilitating the removal of the incontinence pad 1 from the excretion port on the patient's bed frame. Example 5

[0062] In order to ensure that the chair can intelligently correct the student's sitting posture, a general control module is set up;

[0063] refer to Figure 8 As shown, the control module includes a temperature and humidity sensing module and a communication module. The temperature and humidity sensing module is used to: cooperate with the humidity sensor 3 and the temperature sensor 401, be arranged inside the pad body, and detect the temperature and humidity inside the pad in real time. The communication module is used to: be connected to a smart phone, a display screen 2 and a nursing system via Wi-Fi or Bluetooth, and be used to send an alarm to the display screen 2 for the temperature and humidity sensed by the temperature and humidity sensing module, and finally the buzzer 202 and the indicator light 203 are used for warning. By integrating the temperature and humidity sensor, the humidity change in the pad is monitored in real time, and the alarm information is sent to the user or the nursing staff in time, thereby improving the efficiency and quality of incontinence care.

[0064] Working principle: At present, some auxiliary excretion structures can be made on the bed structure for some patients who are paralyzed in bed or incontinent. An opening for installing the incontinence pad 1 is opened at a certain distance around the patient's buttocks. First, in order to ensure that the incontinence pad 1 can be used repeatedly for a long time, a layer of spacer 11 is added on its surface to facilitate the humidity sensor 3 and temperature sensor 401 in the incontinence pad 1 to monitor the patient's urination and defecation. The control and warning functions of the incontinence pad 1 are equipped with a display screen 2. The display screen 2 is displayed through The card sleeve 204 is fixed in a place convenient for patients or medical staff to use. Before use, the spacer 11 is attached to the upper surface of the incontinence pad 1, and the thin net 1101 corresponds to the humidity sensor 3 and the temperature sensor 401 for convenient monitoring, while not affecting the monitoring effect. First, the two ends of the spacer 11 are passed through between the splint 503 and the fixed plate 501, and the outer sides of the splint 503 and the fixed plate 501 are pinched by hand, so that the limit rod 504 on the inner side of the splint 503 is deeply inserted into the fixed plate 501, and the inner side of the limit rod 504 is used to The iron-absorbing layer makes the clamping plate 503 and the fixing plate 501 adsorbed to each other, and the spring 505 set at the end of the limit rod 504 also plays a role in limiting the position of the limit rod 504. After clamping, each clamping mechanism 5 is rotated forward to be flush with the base 102 to play the role of fixing the spacer 11. When it is used later, the monitoring operation is turned on by the switch button 201 of the display screen 2. When the humidity sensor 3 and the temperature sensor 401 are detected to be abnormal, the matching communication module can be used to communicate with the smart phone through Wi-Fi or Bluetooth. The mobile phone, the display screen 2 and the nursing system are connected to send an alarm to each contact end, and contact the patient's relatives and guardians, and at the same time send an alarm to the display screen 2 of the temperature and humidity data sensed by the temperature and humidity sensor module, and then the buzzer 202 and the indicator light 203 warn. If the incontinence pad 1 needs to be removed during use, the push block 6 of the base 102 at the front and rear ends of the incontinence pad 1 can be pushed to drive the slider 2 602 to move outward, and the slider 2 602 drives the straight rod 1 604 to push one side of the rocking plate 10 forward, such as Figure 3 As shown, the arcs on both sides of the rocking plate 10 are arranged oppositely, so when the straight rod 1 604 pushes the rocking plate 10 from one side, the other side moves in the opposite direction, so that the other side of the rocking plate 10 pushes the slider 5 702 of the control card plate 7 inward, so that the card plate 7 moves in the direction of the slide groove 2 10204 and the card groove 10301, so that the card plates 7 on both sides are retracted to the bottom of the base 102, so that the incontinence pad 1 can be easily taken out of the bed. When installing the incontinence pad 1, the movement of the card plate 7 can also be controlled by pressing the block 6 so that it can use the space between it and the base 102 to clamp the edge of the opening for installing the incontinence pad 1. Example 6

[0065] The control module also includes a communication quality monitoring module, which is used to monitor the operation status of the communication module in real time to see if there is any abnormality, and to issue an abnormality alarm;

[0066] The operation process of the communication quality monitoring module includes:

[0067] Real-time monitoring of the operating parameters of the communication module, wherein the operating parameters include wireless signal strength, signal-to-noise ratio, the number of communication connection interruptions per unit time, and the duration of the interruption;

[0068] Extracting the wireless signal strength and the number of communication connection interruptions corresponding to each unit time from the operating parameters to obtain a first evaluation coefficient;

[0069] The first evaluation coefficient is obtained by the following formula: Among them, P 01 represents the first evaluation coefficient; n represents the number of unit times experienced by the communication module operation, and the unit time is 1min-3min; B i Indicates the wireless signal strength value corresponding to the i-th unit time; B e Indicates the minimum wireless signal strength value allowed to meet wireless communication requirements; B min Indicates the lowest value of wireless signal strength that occurs in n unit time; B b Indicates the standard deviation of the wireless signal strength that occurs in n unit time; B f Indicates the maximum floating value of wireless signal strength allowed to meet wireless communication requirements; N i Indicates the number of communication connection interruptions corresponding to the i-th unit time;

[0070] Comparing the first evaluation coefficient with a preset first coefficient threshold;

[0071] When the first evaluation coefficient is lower than a preset first coefficient threshold, the operation quality of the operation state of the communication module is evaluated by using the signal-to-noise ratio, the number of communication connection interruptions corresponding to each unit time, and the interruption duration.

[0072] The technical effect of the above technical solution is: through the communication quality monitoring module, the operation status of the communication module can be monitored in real time, and any abnormalities can be discovered and reported in time. This real-time monitoring mechanism helps to quickly respond to communication problems and reduce service interruptions or performance degradation caused by communication failures. This solution not only considers the basic communication quality indicator of wireless signal strength, but also introduces multiple dimensions such as signal-to-noise ratio, number of communication connection interruptions, and interruption duration to comprehensively evaluate the operation status of the communication module. This comprehensive evaluation method can more accurately reflect the actual situation of communication quality and improve the accuracy of the evaluation.

[0073] By calculating the first evaluation coefficient and comparing it with the preset first coefficient threshold, the scheme can dynamically evaluate the operation quality of the communication module. When the first evaluation coefficient is lower than the threshold, further operation quality evaluation will be triggered, which helps to timely discover potential communication problems and take corresponding preventive measures to avoid the deterioration of the problem. The formulas and parameters in the scheme (such as unit time, wireless signal strength value, signal-to-noise ratio, etc.) can be adjusted and optimized according to actual conditions to adapt to different communication environments and needs. This flexibility and adaptability enable the scheme to be more widely used in various communication scenarios. By real-time monitoring and comprehensive evaluation of the operation status of the communication module, the scheme helps to timely discover and solve communication problems, thereby improving the stability and reliability of the entire system. This is particularly important for scenarios that require continuous and stable communication services, such as the Internet of Things, remote monitoring, and real-time communication.

[0074] In summary, this technical solution effectively improves the operation quality of the communication module and the stability and reliability of the system through real-time monitoring, comprehensive evaluation, dynamic adjustment and early warning mechanisms, providing strong support for various communication applications.

[0075] Specifically, when the first evaluation coefficient is lower than a preset first coefficient threshold, the operation quality evaluation of the operation state of the communication module is performed using the signal-to-noise ratio, the number of communication connection interruptions corresponding to each unit time, and the interruption duration, including:

[0076] When the first evaluation coefficient is lower than a preset first coefficient threshold, extracting the signal-to-noise ratio, the number of communication connection interruptions corresponding to each unit time, and the interruption duration;

[0077] Obtaining a second evaluation coefficient using the signal-to-noise ratio, the number of communication connection interruptions corresponding to each unit time, and the interruption duration;

[0078] The second evaluation coefficient is obtained by the following formula: Among them, P 02 represents the second evaluation coefficient; n represents the number of unit times experienced by the communication module operation, and the unit time is 1min-3min; B i Indicates the wireless signal strength value corresponding to the i-th unit time; B e Indicates the minimum wireless signal strength value allowed to meet wireless communication requirements; S i represents the signal-to-noise ratio value corresponding to the i-th unit time; S min Indicates the lowest signal-to-noise ratio that occurs in n units of time; S e represents the expected signal-to-noise ratio value; T zi T represents the median interruption duration corresponding to the N communication connection interruptions corresponding to the i-th unit time; maxIndicates the maximum disconnection time allowed to meet the wireless communication requirements; T j Indicates the interruption duration corresponding to the jth communication connection interruption corresponding to the i-th unit time;

[0079] extracting the first evaluation coefficient;

[0080] The first evaluation coefficient and the second evaluation coefficient are used to obtain a comprehensive evaluation parameter; wherein the comprehensive evaluation parameter is obtained by the following formula: Among them, P represents the comprehensive evaluation parameter; P 01 Represents the first evaluation coefficient; P 02 Represents the second evaluation coefficient; P y01 represents a preset first coefficient threshold;

[0081] Comparing the comprehensive evaluation parameter with a preset evaluation parameter threshold;

[0082] When the comprehensive evaluation parameter is lower than a preset evaluation parameter threshold, it is determined that the operation state of the communication module is abnormal, and an abnormal alarm is issued.

[0083] The technical effect of the above technical scheme is: on the basis of the first evaluation coefficient, the scheme introduces more dimensional parameters such as signal-to-noise ratio, number of communication connection interruptions and interruption duration, and realizes a deeper and more dimensional evaluation of the operation quality of the communication module by calculating the second evaluation coefficient. This multi-level and multi-dimensional evaluation method can more comprehensively reflect the actual operation status of the communication module and improve the accuracy and reliability of the evaluation. When the first evaluation coefficient is lower than the preset first coefficient threshold, the scheme will further extract parameters such as signal-to-noise ratio, number of communication connection interruptions and interruption duration, and calculate the second evaluation coefficient. Then, by comprehensively considering the first evaluation coefficient and the second evaluation coefficient, the comprehensive evaluation parameter is used for the final judgment. This dynamic adjustment and comprehensive judgment method can more flexibly respond to changes in the operation status of the communication module and improve the adaptability and accuracy of the evaluation. By setting a preset evaluation parameter threshold and comparing it with the comprehensive evaluation parameter, the scheme can accurately identify whether there is an abnormality in the operation status of the communication module. When the comprehensive evaluation parameter is lower than the preset evaluation parameter threshold, the system will issue an abnormal alarm and promptly remind relevant personnel to handle it. This ability to accurately identify abnormal states helps reduce the occurrence of communication failures and improve the stability and reliability of the system. The solution can detect and report potential communication problems in a timely manner by real-time monitoring and comprehensive evaluation of the operating status of the communication module. This helps relevant personnel take timely measures for maintenance and processing to prevent the problem from further deteriorating. At the same time, through the abnormal alarm function, problems can be quickly located and solved, improving the efficiency and response speed of system maintenance. Through multi-level and multi-dimensional operation quality evaluation and accurate identification of abnormal conditions, the solution can enhance the robustness of the system. Even in some extreme cases, if the operating status of the communication module is abnormal, the system can detect it in time and take corresponding measures to respond, ensuring the normal operation of the system and the stability of data transmission.

[0084] In summary, this technical solution improves the operation quality of the communication module and the stability, reliability and maintenance efficiency of the system through multi-level and multi-dimensional operation quality evaluation, dynamic adjustment and comprehensive judgment, and accurate identification of abnormal conditions, providing strong support for various communication applications.
