[0016] The specific embodiment of the utility model is further explained in detail by comparing the drawings and describing the optimal embodiment.

[0017] Embodiment 1:

[0018] This embodiment mainly realizes the reminding control to long sitting, and the long time long sitting of the user is detected, and the buzzer is used to issue a reminder, for example, Figure 1As shown, the sitting intelligent monitoring and reminding control system in the present solution comprises a pressure sensor, which is arranged in the seat cushion to collect pressure data received by the seat cushion; the pressure sensor is connected with a microprocessor, and the output end of the microprocessor is connected to a time delay relay; the normally open contact of the time delay relay is arranged in series in the power supply circuit of the alarm module to control the working state of the alarm module.

[0019] The pressure sensor is arranged in the seat cushion, and the pressure data detected by the pressure sensor is different when a person sits down and when no one sits down. The pressure data is sent to the microprocessor for processing. The microprocessor is a control chip with data processing and control functions. A single-chip microcomputer is used to realize the processing and control functions. Considering the cost and compatibility of software development, a domestic 51 series single-chip microcomputer chip or an STM32 series single-chip microcomputer chip is used to realize the functions.

[0020] The output end of the microprocessor is connected to the time delay relay to drive the time delay relay to work. The time delay relay has a normally open contact. After the normally open contact is triggered to work for a set time delay, the normally open contact is closed. Since the normally open contact is connected in series in the power supply circuit of the alarm module, when the user sits for a set time, the time delay relay is used to control the power supply of the alarm module to work. The alarm module sends a sitting reminder to achieve the purpose of reminding the user to sit.

[0021] The time delay relay can be implemented by using a multifunctional digital display time delay relay, which is an automatic switch device that uses electromagnetic principles to realize time delay control. In the present design, the multifunctional digital display time delay relay is used to set the sitting time. When the pressure sensor detects that the human body is in a sitting position, the time relay starts timing. When the timing time reaches the pre-set sitting time, the normally open contact of the time relay is closed, triggering the buzzer circuit. The alarm module is implemented by using a buzzer, which is an integrated electronic sounder. It is powered by DC voltage. When the normally open contact of the multifunctional digital display time delay relay is closed, the circuit is turned on, the buzzer is powered on to produce sound, thereby realizing the function of sitting reminder. When the seat cushion with the pressure sensor is pressed, the pressure sensor circuit is turned on, the time delay relay starts counting down, and when the countdown is over, the COM and NO terminals of the internal normally open contact of the relay are turned on, the buzzer is powered on to produce a ringing sound to remind the user to get up and move around. When the person leaves the seat cushion with the pressure sensor, the pressure sensor loses weight, the circuit is disconnected, the buzzer stops ringing, and the time delay relay returns to the set value. Figure 1 As shown, the power supply provides stable DC voltage for the entire device to ensure that each part of the circuit works normally. In actual production, all electronic components are installed on a circuit board, and a suitable shell is used for packaging to ensure the safety and aesthetics of the device.

[0022] Example 2:

[0023] The embodiment is based on embodiment 1, and multiple delay controls are added to meet the different delay controls of different people, such as realizing different sitting delay alarm according to different body weight. Because different people have different body weight, the definition of sitting time is different, such as adults and children, whose body weight and exercise amount are different. The sitting time of children is obviously different from that of adults. Therefore, multiple delay relays are set, each delay relay is set to different delay time, so that different delay time can be used to judge sitting according to the collected different pressure, and different sitting alarms can be sent to people with different body weight, improving the pertinence of sitting alarm, and different delay time can be used as sitting time for people with different body weight to send sitting alarm sound after the delay time of delay relay ends. In order to realize this scheme, the delay relays in the embodiment are set to multiple. Each delay relay is set to different delay time, and the normally open contacts of each delay relay are connected in parallel and then connected in series in the power supply circuit of the alarm module; the microprocessor controls one of the multiple delay relays to work according to the size of the pressure signal collected by the pressure sensor.

[0024] As shown in Figure 2 Two relays are taken as an example to introduce them, the two relays are first delay relay and second delay relay, and the corresponding normally open contacts are K1 and K2 respectively. The normally open contacts K1 and K2 are connected in parallel and then connected in series in the power supply circuit between the power supply and the buzzer, and the normally open contacts K1 and K2 are used to control whether the buzzer is powered on or not. After people with different body weight sit on the cushion, because of different body weight, the pressure generated is different, according to the different pressure set in advance, the microprocessor controls the work of different delay relays, and then controls the normally open contacts K1 or K2 to close after the delay is completed, so as to realize different delay alarm. The first delay relay and the second delay relay can set their delay time through pre-adjustment, set different delay time according to the pressure corresponding to different body weight, and then detect the pressure data corresponding to the body weight, control the corresponding delay relay to work and control the corresponding normally open contact to close, so as to realize the delay sitting reminder of different body weight. At the same time, because the scheme is set on the seat, different people will sit on the seat, so as to realize the corresponding reminder of long sitting of people with different body weight.

[0025] In one preferred scheme of the embodiment, a pressure threshold is preset in the microprocessor, and when the pressure value collected by the pressure sensor is less than the threshold, the microprocessor prohibits the output signal to the time-delay relay. In order to avoid false sitting reminder, a minimum pressure threshold can be set, and when the pressure is less than the minimum pressure threshold, it indicates that the object placed on the cushion is not a person, and the sitting reminder is not generated, the sitting reminder function is not started, and the false alarm is reduced. The pressure threshold is set in the microprocessor, and whether to control the time-delay relay to start working can be determined according to the received real-time pressure data, and after determining to start working, the relay is controlled to work and delay.

[0026] In one preferred embodiment, in order to more accurately realize the sitting alarm and avoid false alarm caused by placing an object similar to a person on the cushion, accurate detection and identification of a person sitting on the seat or cushion are needed, and then accurate alarm is realized. In order to accurately identify whether the pressure of the pressure sensor is caused by a person sitting on the seat or an object placed on the seat, a corresponding detection scheme needs to be set, and the embodiment provides two selectable detection schemes, which include:

[0027] One: a vibration sensor is arranged in the cushion, the vibration sensor is used to collect the cushion movement or vibration signal after the pressure sensor is triggered by pressure, and the output end is connected to the microprocessor; the microprocessor determines whether to output the control signal to the time-delay relay according to the signals collected by the vibration sensor and the pressure sensor. Since the difference between a person and an object placed on the cushion is that the person will move, while the object remains unchanged, the microprocessor can determine whether the triggered pressure sensor is a person or an object according to the collected vibration signal, if the vibration signal is detected irregularly after the pressure sensor is triggered for a period of time, it indicates that the triggered pressure sensor is a person, and the microprocessor can realize the sitting alarm after a delay by triggering the time-delay relay; if no vibration signal is detected after the pressure sensor is triggered for a period of time, it indicates that the pressure output of the triggered pressure sensor is an object rather than a person, and the sitting reminder needs to be sent at this time, so the microprocessor controls the time-delay relay to stop working at this time, and prohibits the working of the time-delay relay, thereby avoiding false alarm caused by placing an object.

[0028] Secondly, the microprocessor has a calculation unit built-in, which is used to calculate the fluctuation of the pressure signal collected by the pressure sensor, and the microprocessor determines whether to send a control signal to the delay relay according to the fluctuation of the pressure signal. Due to the difference between people and objects, not only different vibrations will be produced, but also pressure signal changes may be produced due to the movement of people when sitting. Therefore, the calculation unit in the microprocessor is used to calculate the pressure change fluctuation signal within a period of time after the pressure sensor is triggered. If the pressure has a change fluctuation, it is determined that a person triggers the pressure sensor, otherwise it is determined that an object triggers the pressure sensor. If it is a person who triggers, the delay relay is controlled to start working, otherwise the delay relay is prohibited from starting working.

[0029] In a preferred embodiment, due to work reasons, sitting for a long time may be due to work or rest, such as lunch break, etc. Therefore, in order to avoid triggering the long sitting alarm during the rest time and affecting the rest, improve the user experience and intelligent degree, a clock chip and a keyboard module are provided. The output end of the keyboard module is connected to the microprocessor, which is used to set the sleep time range. The output end of the clock chip is connected to the microprocessor, which is used to provide the current time to the microprocessor. The microprocessor stops controlling the delay relay to work when the current time is in the sleep time range.

[0030] The keyboard module can adopt a 4*4 keyboard to input the user's rest time range to the microprocessor. For example, if the rest time range is set to 12:00am to 13:00pm, the microprocessor determines whether the time data is between 12:00am and 13:pm through the real-time time data of the clock chip. If yes, the delay relay is controlled to stop working to avoid the delay relay starting working and controlling the alarm to emit an alarm sound during the rest time. If not, the delay relay continues to work according to the pressure signal to delay and control the buzzer to work after the delay is over. This way can reduce or avoid the false alarm during the rest time to affect the user's rest on the seat.

[0031] After multiple tests, the sitting reminder device can accurately detect the sitting posture of the human body. When the human body sits on the cushion, the pressure sensor can respond quickly, and the time relay starts timing. Within the set sitting time range (such as 30 minutes), the time relay timing is accurate, and when the timing is over, the buzzer can timely emit a loud sound to remind the user to get up and move. Under different pressure environments (such as different weight personnel using), the pressure sensor can still work stably, ensuring the reliability of the device. At the same time, the stability of the device is tested for a long time, and after continuous operation for several hours, the circuits of each part of the device work normally, without failure or abnormality, indicating that the device has good stability and durability. Through reasonable hardware design and debugging, the device can accurately monitor the sitting state of the human body and timely remind when the set time is reached, effectively solving the problem that people neglect to get up and move because of long sitting. The device has the advantages of simple structure, low cost and easy implementation, and has certain practical value and market promotion potential.

[0032] Obviously, the specific implementation of the present application is not limited by the above-mentioned manner, and various non-essential improvements using the method concept and technical scheme of the present application are within the protection scope of the present application.
