Specific embodiment

The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.

A kind of power-assisted chair with alarm function, including seat body 1, servomechanism 2, control system 3, mobile base 4, as shown in Figure 1, being provided with handrail 5 and the chair back 6 in seat body 1, mobile base 4 is movably set in seat body 1, activity By being hingedly fixed in seat body 1, the lower end surface of mobile base 4 connects servomechanism 2, servomechanism 2 for the front end of pedestal 4 Including motor 201, the bottom of seat body 1 is arranged in motor 201, and one end of the drive shaft of motor 201 is connected with crank block The other end of one end of mechanism 202, slider-crank mechanism 202 is connect with the lower end surface of mobile base 4.

The upper surface of mobile base 4 is equipped with cushion, is equipped with control system 3 in cushion, and control system 3 plays the role of observing and controlling, According to each point pressure sensor signal and clock signal of acquisition, intelligent recognition simultaneously issues corresponding control instruction, such as Fig. 2 institute Show, control system 3 include single-chip microcontroller 300 and connect respectively with single-chip microcontroller 300 pressure sensor 301, clock module 302, Power module 303, drive module 304, display module 305, alarm module 306 and communication module 307, drive module 304 connect The motor of servomechanism 2, driving motor drives mobile base 4 to rotate after drive module 304 receives the signal of single-chip microcontroller 300；

Wherein, button 501 is provided on handrail 5, button 501 is electrically connected with the single-chip microcontroller 300, when user needs to stand up Button press 501 will stand up signal by 300 transmission drive module 304 of single-chip microcontroller, and drive module 304 drives 2 band of servomechanism Dynamic mobile base 4 rotates.

Single-chip microcontroller 300 is the core of entire control system 3, is responsible for signal acquisition, logic judgment and control signal output；Pressure Force snesor 301 is distributed on cushion, is acquired pressure signal everywhere and is conveyed to single-chip microcontroller 300；Clock module 302 is entire control It makes 3 systems and clocking capability is provided；Power module 303 connects external power supply, and it is straight that 220V alternating current is converted into 24V, 5V and 3.3V Galvanic electricity provides satisfactory voltage for entire 3 each section device of control system；Display module 305 mainly shows the time and mentions Awake text；Alarm module 305 issues different grades of alarm signal by the modes such as sound and seat cushion vibration；Communication module 306 For emergency, pass through communication module 307 when control system 3 identifies that seat is in an emergency using human body to nothing The communicating terminal of line connection sends warning message.

Although the old and the weak personnel have certain mobility with itself, exists to rely on after sitting down and itself stand again Get up this highly difficult problem.When the power-assisted signal that will stand up of single-chip microcontroller 300 is transferred to drive module 304 in control system 3, drive Module 304 drives servomechanism 2 that mobile base 4 is driven to rotate, while what is be distributed on the real-time acquisition cushion of single-chip microcontroller 300 respectively presses The clock signal of force snesor 301 signal and clock module 302, by detecting seat cushion pressure difference, intelligent recognition is to cooperate power-assisted It stands up function.After user stands up instruction sending, in setting time T_qInterior, the mean pressure variations value Δ F of cushion is more than or equal to Setting value Δ q₁When, mobile base 4 completes power-assisted and stands up function；If the mean pressure variations value Δ F of cushion is less than Δ q₁When, it is System assert that user does not have most basic condition of standing up, i.e. user is likely to occur the situations such as uncomfortable or strength deficiency, mobile base 4 Restore to horizontality, no longer rises, flow chart is as shown in Figure 3.

There are long-time sedentary working, study, game by most personnel, lack movement, body guarantees a kind of fixation for a long time Sitting posture, influences health, serious possibly even to lead to occur burst diseases such as " overworking deaths ", Intelligent seat according to The clock signal of each point pressure sensor 301 signal and clock module 302 that are distributed on acquisition pedestal in real time, calculates and obtains each point Pressure mean values and changing value, and consider the time accumulated value under different pressures situation of change, it shows the sitting duration, makes The warnings such as sitting, sedentary, the burst disease that is seated judgement.The process of difference warning judgement is as follows:

Sitting warning: single-chip microcontroller 300 acquires 301 signal F of pedestal multipoint pressure sensor in real time₁、F₂……F_n, and solve The average F of multipoint pressure value_j, and show the sitting duration；As multipoint pressure average value F_jAdd up in the range of setting super Cross the time T of setting₁, then it is determined as sitting, issues sitting alarm signal, flow chart is as shown in Figure 4.

Sedentary warning: single-chip microcontroller 300 acquires pedestal multipoint pressure sensor signal F in real time₁、F₂……F_n, setting Time T₂It is interior, if average pressure value F_jChanging value Δ F is in a certain range Δ q₂Interior variation, then be determined as sedentary, issues long Motionless alarm signal is sat, driving motor 201 drives mobile base 4 to swing, and forces moving body of standing up, and flow chart is as shown in Figure 5.

The burst disease that is seated warning: single-chip microcontroller 300 acquires 301 signal F of pedestal multipoint pressure sensor in real time₁、F₂…… F_n, in the time T of setting₃It is interior, if multipoint pressure value F₁、F₂……F_nIn a certain range Δ q₃Interior variation is then judged to happening suddenly Disease issues burst disease alarm signal to the communicating terminal of wireless connection, and flow chart is as shown in Figure 6.

A kind of power-assisted chair with alarm function of the present invention, the advantage is that: the intelligence power-assisted chair acquires bottom in real time The multipoint pressure sensor signal and clock signal being distributed on seat compare seat pressure difference by detection, and intelligent recognition is to match Power-assisted is closed to stand up function；Analysis compares multipoint pressure sensor signal numerical value and changes with time situation, not to sitting, sitting Move, be seated burst disease situations such as judge and issue the alarm signals of different brackets different modes.
