Abstract

An emergency calling device is provided, which belongs to the technical filed of medical monitor facility. The utility model comprises three ball switches. The three ball switches enclose a cone at the included angle of 120 degree. The triggering eduction feet close to the center of the three ball switch are communicated with the positive polar of the power source via lead; the triggering eduction feet close to the peripheral are communicated to the negative polar of power source via lead. The COM feet of the three ball switches are respectively led to the I / O input of the singlechip computer. With the combination of the singlechip computer, an encoder and a wireless emitting module, the utility model can be placed into a plastic box and worn around people's neck. According to the principle of gravity, when people fall down accidentally, the shape of the three ball switches can be utilized for judgment. One normative status and seven abnormal statuses are arranged. The alarming signal will be emitted under abnormal status.

Description

A kind of urgent call device

Technical field

A kind of urgent call device of the present invention can be used with the home alarm device, as the equipment of medical aid.

Background technology

At present, the urgent call device of using in family's burglar alarm and some domestic medicine rescue equipment all adopts button to trigger the radio alarming mode.Can solve antitheft problem like this, but be used for medical aid with regard to defectiveness.If what the user sent out is the disease for the treatment of cardiac and cerebral vascular diseases, usually be to fall into a coma or paralyse, button just can not work.This will badly influence patient's life security.

Summary of the invention

The purpose of the present utility model provide a kind of wear with oneself not only can be with hand by the urgent call device that triggers but also can trigger automatically.It is by 3 pellet shot from a slingshot switch T1, T2, T3, an emergency call button, and one-chip computer, scrambler, wireless transmitter module and hummer are formed.It hangs on people's the neck as necklace, hangs from above in the shirtfront; Perhaps be worn on the side waist.

According to the action of gravity principle, when the normal person wore, capsule was sagging naturally.Metal Ball in the pellet shot from a slingshot switch is because action of gravity makes that the COM pin state of T1, T2, T3 is respectively (1,0,0).By to the one-chip computer programming, make one-chip computer assert that this is a unique normal condition.After the people fell down, the COM pin state of T1, T2, T3 can be changed by the effect of gravity, as presented (1,1,0) (0,0,0) etc.The state that in a single day one-chip computer detects non-(1,0,0) will be opened hummer (6) " toot ", " toot " sound, and prompting will be reported to the police.If the wearer is normal, can clicks emergency call button (5) and remove warning.Otherwise the emission of open wireless electricity is reported to the police after ten seconds.

If the wearer is clear-headed, need the people when sending urgent call, can pin emergency call button (5) 3 seconds, can the emission of open wireless electricity report to the police.

Specific embodiments

3 two-way pellet shot from a slingshot switches (1) surround a circular cone build, the position of each pellet shot from a slingshot switch such as Fig. 1.Angle between T1, T2 and the T3 is identical.Each pellet shot from a slingshot switch and base plane are the angle greater than 20 degree, Fig. 2.Each pellet shot from a slingshot switch also relatively the origin-location make parallel shifted.

3 pellet shot from a slingshot switches (1) are received positive source by the triggering leading foot of that end at center with the lead connection, and the triggering pin of outer that end that encloses is communicated with lead receives power cathode.The COM pin of 3 pellet shot from a slingshot switches is drawn out to the I/O input port of one-chip computer respectively.Fig. 3.

One-chip computer (2) connects scrambler PT2262 (3), the transmission of control wireless signal with an output I/O mouth.Use PT2262 to be because codec such as the PT2272 that the many uses of alarm on the market now match with it.

PT2262 connects wireless transmitter module (4), and the frequency of wireless transmitter module is identical with the reception main frame.Fig. 3.

3 pellet shot from a slingshot switches (1) are connected shown in Fig. 3 wiring diagram, be welded on the pcb board, mix 3 volts of batteries and put into a plastic cement capsule, and capsule connected wearing on people's neck with flexible cord, be suspended on people's front, T1, T2, the T3 condition of laying in box is to guarantee that pellet shot from a slingshot switch T1 is perpendicular to the ground.

The noun explanation

The pellet shot from a slingshot switch: be vibration switch again, cylindrical.The opering characteristic of electric apparatus and mercury cut-off are approximate, the inside is with one or the alternative mercurys of two metal hoodles, the golden guide pin in two ends is (ON) short circuit trigger end, silver color one end is shared (COM) point, be lower than 15 when spending when guide pin one end is provided with the angle, be lower than the short circuit trigger end and common point (COM) conducting of level one end.

Claims

1, a kind of urgent call device is characterized in that by 3 pellet shot from a slingshot switch T1, T2, T3, an emergency call button, and one-chip computer, scrambler, wireless transmitter module and hummer are formed.

2, urgent call device according to claim 1 is characterized in that the position that they are put is in circumference: T1 (2) 90 degree, T2 (1) 210 degree, T3 (8) 330 degree.

3, urgent call device according to claim 1 is characterized in that 3 pellet shot from a slingshot switches are to the equal projection and be angle greater than 20 degree of that end of the center of circle.

4, urgent call device according to claim 1, it is characterized in that each pellet shot from a slingshot switch also relatively the origin-location make parallel shifted.

5, urgent call device according to claim 1 is characterized in that 3 pellet shot from a slingshot switches link together and are wired to positive source or high level to the trigger electrode of that end of the center of circle.
