Description of the invention: [Technical field of invention] A "control method and structure of an air bed controller", especially a low-cost method for quickly adjusting the air intake information of an air bed, and using the method The air bed controller developed. [Prior Art] According to the air mattress, in addition to providing a comfortable sitting environment, it is more widely used in medical applications, especially for the elderly, patients with spinal cord injury, brain stem injury patients (vegetative), stroke patients, heavy = dementia The care of patients with symptoms can prevent hemorrhoids, and for patients with trauma such as burning, scalding, motor dysfunction caused by rare diseases or injuries, and resulting in patients unable to turn over, the automatic decompression or boosting air cushion The bed will reduce the pain caused by the patient's weight loss on the damaged skin and reduce the pain caused by poor posture. With the wide use of air bed, people who use air bed have high, short, fat, thin and different 'body weight is not @, and the internal pressure of comfortable bed can withstand gender (men and women), age (young age) It is also different, therefore, how to design a controller for adjusting the air bed is an important issue. The conventional air bed design 'mainly consists of a constant pressure phase air bed gas from an air intake pump. The air bed has a certain pressure. When the air pressure is too high (for example, the human body lies on the bed) Excessive pressure will force the gas out of the check valve, but this is only 201018427. The average pressure value is provided by the user. 'The above-mentioned multiple patients can't reach the pressure that is adjusted to be extremely comfortable due to their condition. Design; therefore, a hand-controlled pump controller is designed to be manually adjusted by the experience of the medical staff or by asking the patient's feelings to manually adjust the amount of air intake to adjust the pressure in the bed. Most of the suffering at that time could not provide a sense of truth and the personal experience of the medical staff was not objective enough. If there was a mistake: it would not be automatically corrected, so it was not an ideal controller and it was still not painted. Later, there is a more sophisticated electronic controller, by inputting the patient's height, weight, age, condition and other information, and then reading the better pressure value in the database to start the controller's pump. = The amount of air intake in the field, but the price of this precision electronic device is higher than that of Ambon, and it is easy to damage. Most of the small and medium-sized medical clinics or individuals are generally equipped with limited equipment, which makes it comfortable. The air bed is not popular, so it is the research and development of the present invention to design a low-cost air bed automatic controller to make the comfortable air bed popular and benefit the people. [The present invention] Carry out the following steps: (1) first set the initial first pressure value of the controller; (2) set the first pressure to a stable value of the air bed; (3) set a second second pressure value. Among them, the second The pressure is smaller than the first pressure; (4) the second pressure of 201018427 is maintained at a stable value for the air bed; (5) the time difference from the stable first pressure value to the third pressure is stabilized; (6) on The time difference of the step is revealed, and the corresponding mattress load and the optimal pressure value are extracted; (6) the air bed is inflated to the final pressure value. Accordingly, the manual is more accurate and more expensive than the conventional one. The precision machine is more cost-effective and convenient to operate, and is a feature of the present invention. [Embodiment] In order to enable the reviewing committee to clearly understand the contents of the present invention, only the following description is used in conjunction with the drawing, and the description is as follows. As shown in Fig. 2, the "control method of the air cushion controller" disclosed in the present invention includes the following steps: 1. Setting an initial first pressure value (i 〇): firstly, designing an appropriate pressure, at this time, Estimated to be an appropriate pressure value when the air bed has a load (ie, manned), such as the first pressure (P 1 ) in Figure 2. 2 · Keep the first pressure on the air bed to maintain a stable value (^ i: this maintenance constant is mainly achieved by the adjustment of the air pump and the constant pressure valve, and the state of maintaining the stability is as shown in the line of Fig. 2 (s 1 Shown ° 3 . Set a subsequent second pressure value (12): wherein the second pressure (P2) is smaller than the first pressure (pi). 5 201018427 4 . Keep the second pressure value on the air bed Stable value (i 3 the state of maintaining stability as in the line segment (s 3 ) of Fig. 2. 5 · Calculation of the conversion from the stable first pressure value to the second pressure value and achieving a stable time difference (i 4 ): with the present invention As shown in the second figure, the time difference (Δt) is generally about several seconds, from the first pressure (P1) to the second pressure (p2) until the stability (equilibrium) is achieved, as shown in Fig. 2 of the present invention. The inclined line segment (S 2 ) shown as the time difference (Δ t ) is shorter, the closer the oblique line segment (S 2 ) is vertical (ie, the steeper), that is, the load on the air bed (ie, the patient's weight) is heavier. On the contrary, it is lighter, and this information can be used as the basis for determining the best final air bed bed inflation. Poor, find the corresponding mattress load and the best pressure value (1 5): the best pressure value is the general medical calculation and test data, not the creation of the present invention 'direct access to existing experimental data The data can be omitted, and will not be described here. 7. Inflate the air bed to the final pressure value (1 6 ). Referring to Figure 3, the structure of the air bed controller of the present invention includes: The central processing unit (20) is a unit of logic operation and control. A service unit (30) for controlling the pump (3 1 ) and 6 201018427 constant pressure valve (3 2) to the air boring machine (Fig. The intake air is not constant and is regulated by the central processing unit (20). A database (40) is the pressure value data corresponding to different body weight, age, and name. See Figures 1 and 3. The central processing unit (2 〇) indicates that the air bed is inflated by the feeding unit (3 0 ) regulating the pump (3 1 ) and the constant pressure valve (3 2 ), respectively, and the pair of air bed inflation includes at least Having: a higher first pressure value and a lower second pressure value by the first pressure The value is converted to the second pressure value and maintained at a constant time difference, and the final pressure value is made in conjunction with the data of the database (4 。). As described above, the present invention will have the following advantages when implemented: 1. Control of the month of the month Because it is an automatic control design, it is more convenient and more precise than the manual control. 2. The automatic control of the present invention is different from the expensive cost of the conventional precision machine. More f, while in use, do not need to enter the patient's height, weight, age, surname and other data, to automatically capture data by the inclination or time difference of linear data, reduce manual errors It is more convenient to use, and is another preferred embodiment of the present invention, which is only the preferred embodiment of the present invention and 7 201018427
