Abstract

A mobile security system, which includes a warning signal transmitter unit installed in the place or equipment to be protected, an auto dialing unit having a signal receiver, and a cellular phone coupled to the auto dialing unit, wherein when the warning signal transmitter unit detects an abnormal condition, it immediately sends a warning signal to the signal receiver by radio, and the signal receiver immediately drives the auto dialing unit to dial a particular telephone number upon receipt of the warning signal, so as to inform a particular person or security center to take the necessary step. The auto dialing unit can be a mechanical design, or an electronic design as desired.

6. A mobile security system comprising a cellular phone and an auto dialing unit built in said cellular phone, said cellular phone comprising a particular key button set driven to dial a set telephone number, and a switching circuit controlled to drive said particular key button set to dial a set telephone number, said auto dialing unit comprising a circuit board having output circuit connected to said key button set through said switching circuit, and a signal receiver installed in said circuit board for receiving a radio warning signal from an external warning signal transmitter means for driving said switching circuit to switch on said particular key button set, causing said particular key button set to dial a set telephone number.

7. The mobile security system of claim 6 wherein the said particular key button set can be formed by one or more than one key button.

8. The mobile security system of claim 6 wherein further comprising a power supply device for providing said cellular phone and said auto dialing unit with the necessary working electricity.

9. The mobile security system of claim 6 wherein said auto dialing unit further comprising a battery power supply for providing the necessary working electricity to said circuit board and said signal receiver.

10. The mobile security system of claim 6 wherein the said circuit board further including a voice player unit thereof such that the said voice player unit and the voice-controlled function of the cellular phone can be switched on simultaneously after the said signal receiver installed in the said circuit board receives a radio warning signal from an external warning signal transmitter means, then, the said cellular phone will dial a preset telephone number by a special voice producing from the said voice player unit.

11. An auto dialing unit used in a mobile security system, comprising a rack, an adjustable cellular phone carrier board, an actuating bar, a control device, a movable pressure device for driving said actuating bar up and down, a driving device, and a power supply unit, wherein:

said rack comprising two opposing vertical boards arranged in parallel, and a horizontal board connected between said vertical boards, said vertical boards each comprising a longitudinally extended step structure, a substantially rectangular top recess on the middle, and a buffer device mounted in said top recess;

said adjustable cellular phone carrier board is supported on said horizontal board inside said rack by vertically adjustable positioning means to carry a cellular phone, having a sliding locating plate inserted into a longitudinal sliding groove thereof and fixed thereto at the desired location by a tightening up screw to hold a cellular phone in place;

said actuating bar is a U-shaped bar pivoted to said vertical boards of said rack and turned between a first position where said actuating bar is disposed outside the top recess at each of said vertical boards, and a second position where said actuating bar is disposed in the top recess at each of said vertical boards and supported on the buffer device in the top recess at each of said vertical boards, comprising two parallel side arms each have a first end respectively pivoted to said vertical boards of said rack and a second end, a transverse arm connected between the second end of said side arms, and a sliding button mounted on said transverse arm and moved between said side arms;

said control device comprising a control circuit board mounted on the horizontal board of said rack at a bottom side, and a signal receiver installed in said control circuit board for receiving a radio warning signal from an external warning signal transmitter means;

a movable pressure device comprising two vertical movable rods respectively inserted through a respective through hole at the top recess at each of the vertical boards of said rack, two hook plates respectively and fixedly mounted on said vertical movable rods at a top side for hooking up said actuating bar when said actuating bar is turned to said second position, a horizontal pressure plate connected between said vertical movable rods suspended below the horizontal board of said rack, and two compression springs respectively mounted on said vertical movable rods and stopped between the vertical boards of said rack and said hook plates;

said driving device comprising a motor fixedly mounted inside said rack below said horizontal board, said motor having an output shaft, and a cam fixedly mounted on the output shaft of said motor and peripherally disposed in contact with the horizontal pressure board of said movable pressure device;

said power supply unit is a battery box mounted in said rack and connecting to said control device and said driving device by circuit to provide the necessary working voltage;

when a cellular phone is placed on said cellular phone carrier board and secured in place by said sliding locating plate, said actuating bar is turned to said second position and retained in place by said hook plates, enabling said sliding button to be aimed at a key button for making calls at the cellular phone installed in said cellular phone carrier board, and said control device drives said motor to rotate said cam through two runs when said signal receiver receives a warning signal from an external warning signal transmitter means, causing said actuating bar to be pulled down, so that the key button for making cells of the cellular phone is triggered twice by said sliding button to call a predetermined telephone number.

12. The auto dialing unit of claim 11 wherein said adjustable cellular phone carrier board has one end mounted with a U-bar having a bottom screw rod inserted through a hole at the horizontal board of said rack and screwed up with an adjustment nut for adjusting the elevation of said adjustable cellular phone carrier board relative to the horizontal board of said rack, and an opposite end coupled to a link having a distal end pivoted to a screw rod and screwed up with an adjustment nut for adjusting the elevation said adjustable cellular phone carrier board relative to the horizontal board of said rack.
