Example two: as a further development or in parallel or alternatively independently, the first calibration of the state of straightness can be carried out without a person triggering the sensor of the position of the backrest; a sensor which triggers the position of the backrest in the use state; the person is judged to be in a leisure sitting posture state after leaning. The technical scheme of the invention has the following substantial technical effects and the realization process: in addition to the basic seat judgment and sensing, the backrest condition is further judged, and the working state and the leisure state are further judged. The uncertainty of video monitoring is broken through.
Example three: as a further development or a parallel or optionally independent solution, a pressure sensor is arranged on the backrest; when the person leans against the backrest for rest, the person is proved to be in the non-working sitting position.
Example four: as a further improvement or a parallel scheme or an optional independent scheme, more than one height sensor (2) is arranged on the backrest; the height of the backrest is greater than the height of a person sitting down; the highest height sensor (2) which can be triggered by a person in a sitting posture is measured in the first step of straight state calibration; when the height sensor (2) which can be triggered by the person in the sitting posture state cannot be triggered in the using state, the rickets spinal non-straightness of the person is judged. The technical scheme of the invention has the following substantial technical effects and the realization process: furthermore, the spine condition of the person is measured and controlled by a rear height sensor, and it should be noted that the height measurement and control at the position and the judgment mode of the position of the sensor triggered below the front edge can be used together, or only one of the height measurement and control and the judgment mode can be used.
Example five: as a further improved scheme or a parallel scheme or a selectable independent scheme, the central control system is in communication connection with a power part for lifting the seat, the power is any one of a lifting cylinder and a motor, when the motor is used, a power output shaft of the motor is a threaded shaft, the threaded shaft is in threaded connection with the seat lifting part (6), and the seat lifting part (6) comprises a threaded hole; the rotation of the threaded shaft can drive the seat lifting part (6) to further drive the seat to lift. The technical scheme of the invention has the following substantial technical effects and the realization process: the utility model provides an implementation structure of electric lift chair, similar implementation structure all is in the protection of this patent.
Example six: as a further improvement or a parallel scheme or an alternative independent scheme, the base (8) comprises a weight sensor which can measure the weight of the person after sitting down; in the first step, the weight of the person is measured, and the weight data is measured every ten minutes during use, and it is determined whether the user is using the apparatus based on the weight data. The technical scheme of the invention has the following substantial technical effects and the realization process: the system can judge whether a person sits in disorder on the station or not, and the station working secret possibly caused runs off.
As a further improvement: when the person sitting at the position is determined not to be the person who should sit, the central control system is in communication connection with the silence system to give an alarm and send an alarm short message to the boss.
Example seven: as a further development or in parallel or alternatively independently, the seat comprises a switch which can control more than one sensor and the switch of the central control system. The technical scheme of the invention has the following substantial technical effects and the realization process: can be opened or closed; after being closed, the chair is used as a common chair.
Example eight: as a further development or in a side-by-side or alternatively independent solution, the table is a fixed height table or a table that can be raised and lowered. The technical scheme of the invention has the following substantial technical effects and the realization process: the table capable of being lifted is lifted by a motor;
referring to the drawings: the lifting switch 14 is a hydraulic lifting switch of the existing lifting seat; can be lifted after being opened; the middle part can also be assisted by a jacking mechanism; the table lifting power part 21 can drive the table on the table lifting power part to lift. Of course, the table herein serves as an auxiliary structural and optional item.
That is, in use, when the human spine is bent, the table lifting power part 21 can be controlled by the central control system to lift the table; one has to straighten the spine.
Example nine: as a further development or in parallel or alternatively independently, the table edge comprises more than one pressure sensor (15); the people can not trigger a plurality of pressure sensors when working, when the people lie prone on a desk and are not good for the spine, the triggered sensors are inconsistent with the sensors which normally work in position and number, and then the spine of the people is judged to be bent. The technical scheme of the invention has the following substantial technical effects and the realization process: the position is a new judging mode for judging that a person sleeps on stomach, and the position can be comprehensively used in the lifting linkage with a chair and the lifting linkage of a table.
There are three separate schemes as follows: three separate embodiments are provided:
example ten: a sitting posture adjustment system for a medical height sensor for avoiding spinal curvature comprises an office chair, wherein the office chair comprises a backrest (1) and a base (8), and is characterized in that more than one height sensor (2) is arranged on the backrest; the height of the backrest is greater than the height of a person sitting down; the highest height sensor (2) which can be triggered by a person in a sitting posture is measured in the first step of straight state calibration; when the height sensor (2) which can be triggered by the person in the sitting posture state cannot be triggered in the using state, the situation that the rickets and the rachitis are not straight is judged;
when the sitting posture is not standard, the following operations are carried out: 1. reminding; 2. the chair is actively lowered, so that the spine of a person needs to be straightened if the arms of the person want to maintain the desk surface for working.
