New Description: [New Technology Target Area] This creation is a bed-away sensor, especially for the technical field of sensing whether the user has left the mattress for a long time and issued a warning signal. [Prior Art] > Due to the rapid changes in technology and the improvement of quality of life, there is no big bet and effort on the use rate or efficiency of things in various fields, like a warning structure, in the current medical or rehabilitation It is the main appeal, because its design makes it easy to control or prevent accidents, such as demented elderly or unconscious patients. In particular, advances in medicine have prolonged the lifespan of people, but this has led to an increase in the medical needs of demented elderly or unconscious patients; however, in nursing homes or nursing homes, often five to ten patients are assigned a nurse or Caregivers, the human resources are obviously insufficient, making it an important issue to prevent accidents. At present, the warning structures used in general medical or rehabilitation are all connected with external large-scale instruments and equipment, providing rapid support services when patients are in a state of emergency. However, in the above design, there are indeed many defects in the use and application, such as false alarms, which cause the nurses or caregivers to be exhausted, increase the load of human resources, and the cost of large instruments and equipment is not ordinary. Family care can afford. In order to meet the above-mentioned objectives, it is desirable to design a bed sensor that is simple in structure, 5 M335279 and which is not easy to cause accidental contact with the elderly or patients, in order to reduce the demand for human resources load. Based on years of research and many practical experiences, the creator has researched and designed the topic and discussed the topic. In this paper, a bed-away sensor is proposed as the implementation and basis of the above-mentioned expectation. ~ [New content] In view of the above-mentioned issues, the purpose of this creation is to provide a sense of detachment from the bed. The system is equipped with a drama at the bottom of the mattress. _Open the mattress and not lie back again, and then issue an alarm to remind the caregiver to go to the viewing. The x edge is that, for the above purpose, the bed-distractor according to the present invention is suitable for a carrier-user-mattress bed-away sensor comprising at least a plurality of sensors, a control device and a warning device. The warning device is electrically connected to the control device, and the sensors are arranged under the mattress in a predetermined arrangement. The control device is electrically connected to the sensors, which are triggered to initiate the weaving when the user is on the mattress. When the _ material remaining is not located on the mattress, when the woven material is opened, and if the sensors are not sensed to be placed on the mattress for a predetermined time, the control device (4) alerts The device issued a warning message to enable the review board to have a better understanding and understanding of the technical features of the creation and the effectiveness achieved. The following examples and related drawings are provided for assistance and detailed. The description of the text is as follows. 6 M335279 [Embodiment] Please refer to FIG. 1A to FIG. 1C together. FIG. 1A is an exploded view showing a preferred embodiment of the bed-away sensor of the present invention, and FIG. 1B and FIG. A schematic diagram of the actuation of the bed sensor. In the figure, the bed sensor 1 is used for a mattress 2, and the bed sensor 1 has a plurality of sensors 11, a control device 12, a rubber pad 13, a plurality of springs 14, an upper cover 15 and a Base plate 16. The Lu sensors 11 are disposed on the bottom plate 6 in a predetermined arrangement, such as a matrix arrangement, and each of the sensors 11 are electrically connected in parallel. The sensor 11 can be a micro switch, and the bottom plate 16 can be a large circuit board. The matrix arrangement is preferably an arrangement of three columns and eight rows, or an arrangement of four columns and six rows, mainly adjusting the arrangement according to the size of the mattress, so that the sensor 11 can be covered on the mattress 2. Bottom 21. The rubber pad 13 has a plurality of through holes ι31, which are attached to the bottom plate %% and allow the sensor 11 and the spring 14 to pass through the through hole 131 to contact the upper cover 15. Wherein, the thickness of the rubber pad 13 is slightly smaller than the sensor η, which is approximately equal to the height of the button head of the sensor 11. The function of the rubber pad 13 is to disperse and sense the pressure of 11 11 , that is, when the pressing force is applied to the lowest point on the crucible 11 , the height of the entire sensor 11 is equal to the height of the rubber pad 13 to protect the sensor U. And extend its service life. A spring hole is passed through the through hole 131 of the rubber pad 13 so that one end thereof comes into contact with the bottom plate, and the other end is in contact with the upper cover 15. The upper cover 15 is attached to the sensor 1 rubber pad 13 and the spring 14, and is combined with the bottom plate 16 to wrap the above-mentioned member. Here, the elasticity of the spring 14 can support the mattress 2 and other objects, 7 M335279 such as the background weight of the pillow, the quilt and the mattress 2, so as to prevent the user from placing other items on the mattress 2 and accidentally touching the sensor. The condition of η. In the present embodiment, eleven springs are preferably provided in the armor and are disposed under the mattress 2 on average. The upper cover 15 is used to evenly distribute the pressure onto the sensor 11, and the feeling of discomfort during use can be eliminated. The control device 12 is electrically connected to the plurality of sensors 11. When the user is on the mattress 2, as shown in Fig. 1B, the weight of the user 3 causes the bottom 21 of the mattress 2 to be pressed against the sensor 11, causing the sensor to be triggered to activate the control device 12. After the user leaves the mattress 2, the elasticity of the mattress 2 itself and the elasticity of the magazine 14 restore the mattress 2 to its original shape without pressing the sensor n as shown in Fig. 1C, so the sensor 1丨If it is sensed that the user is not located on the mattress 2, the drive control device 12 starts timing, and if the sensor n does not sense that the user is located on the mattress 2 within a predetermined time, the sensor u is in a If the mattress 2 is not pressed again within the predetermined time, the control device 12 drives the alert device 122 to issue a warning message. The control device 12 is preferably a disconnected timing device, such as a device consisting of a charging circuit and a logic circuit. The alerting device 122 can be composed of a buzzer, a π8, a illuminating component or a combination of the above components for issuing a warning message to remind others. Referring to Figures 2 through 2C, respectively, a block diagram of an embodiment of the present invention, a circuit diagram of the sensor, and a circuit diagram of an embodiment of the bed-away sensor are shown. In the second diagram, the two ends of the sensor u are electrically connected to the charging circuit 121 of the control device 12, and the Ρ1 terminal is connected to a high potential voltage source, and the Ρ2 terminal is grounded. When the user is on the mattress 2 such that the sensor 11 is pressed by the mattress 2, the Ρ1 and Ρ2 ends form a path, and the voltage value of the pi terminal of the 8 M335279 is changed to activate the control device 12. If the user leaves the wide pad 2, the sensor 11 is not touched and restored to its original state, so that the pι end and the striking 2 form an open circuit and the pi end returns to a high voltage value, so that the charging circuit 12i starts charging. Here, the charging circuit 121 can be implemented with a variable resistor and a capacitor. ^ The electric circuit 121 is charged to a preset voltage and the sensor n has not been touched, and the electric circuit 121 drives the logic circuit 123 to trigger the warning device to send a warning signal to notify the caregiver. Therefore, the system designer can set the required off-bed detection time by adjusting the preset voltage or the charging speed of the charging circuit 121. Please note that for the convenience of explanation, the 2A figure will show a sensor, but in fact, the bed-sensing of the present invention includes a plurality of sensors 11 disposed under the mattress 2, and a plurality of sensors u Connected in parallel, as shown in Figure 2B. The ?1 and ?2 terminals shown in Fig. 2B are the P1鳊 and P2 terminals of Fig. 2A, so as long as any one of the sensors is pressed, the ends of the ends and the ends of the Ρ2 form a path and start control. Device 12. Please refer to the 帛2C diagram, which is the circuit diagram of the implementation of the bed-away sensor. In the figure, the circuit of this embodiment mainly includes a variable resistor Μ, a capacitor 42, two NAND logic elements 43, a transistor, and a relay voltage of 45 ° when the user is placed on the mattress 2 The P1 terminal and the P2 terminal form a path, and there is no voltage difference between the X PI and P2 terminals, so the capacitor does not charge. When the user leaves the mattress 2, the P1 terminal and the P2 terminal form an open circuit, so the π terminal returns to the high potential +V, and the capacitor 42 starts to pass through the path of the variable resistor 41 to be charged. As the capacitor 42 continues to charge, the voltage value at the P3 terminal gradually rises by g. When the voltage value of the turbulent terminal exceeds the logic Logic of the NAND logic device, for example, 5 V, the first NAND logic device 43 is driven to output. The second NAND logic element 43 outputs the voltage value of the logic 1, and enters the M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M When the user returns to the mattress 2 before the voltage value of the P3 terminal exceeds the voltage value of the NAND device 43, the P1 terminal and the P2 # form a pass, and the valley 42 stops charging, and the alert device 122 does not. Will be triggered to issue a warning = tiger. Therefore, the time required to charge the capacitor 42 such that the voltage value at the p3 terminal exceeds the voltage value of the logic 1 of the second:::1 is the departure detection time. When the room comes back from the mattress, the warning device (2) will not issue Lu Buhao, which can reduce the load on the caregiver. Control ====Adjust the resistance value of the variable resistor 'to adjust the time of the _ _ length of charge to adjust the time of the bed detection time ^ to avoid the user 3. Because the rollover movement or short time to turn into the false trigger device 122 The problem. ...and & Yuli === It can be seen that the improved feature of the bed-sensing device of this creation is: leaving the mattress, causing the control device to issue a warning message, change ==: when the body is turned over and falls off the bed, the caregiver cannot The second is to create / on the above mentioned materials, (four) for the limited.
