Abstract

A security system is activated by a remote control (A) via a main relay (B) and an alarm signal is generated by a sensor unit (C) with at least one sensor. The alarm signal is processed in the PLC control units (D, F, G, H, I) and with a recording device (K), and the alarm information is transmitted in the form of adata set via a mobile telephone. The PLC control units are client-specifically programmed with a computer (PC) during the start-up process and the information is transmitted to them via a mobile line (50, 51, 52). The invention is suitable for use in the monitoring of vehicles and security cases. In particular, the security device can be integrated into a satellite locating system with which the position can be represented on a monitor.

Claims

1. A security system for monitoring objects, comprising:

a digital recording device having at least one emergency message; and

a mobile telephone having at least one preselected emergency number;

a first Programmable Logic Controller (PLC) controller for initialing monitoring;

a second PLC controller for repeating an alarm signal; and

third, fourth, and fifth PLC controllers for activating a mobile telephone and a digital recording device;

at least one sensor for generating an alarm state connected to the first PLC controller;

a main relay for controlling the first PLC controller and which can be operated by a remote control;

a computer having mobile lines connectable to the five PLC controllers for programming the five PLC controllers; and

a data set for transmission to the mobile telephone including alarm information;

wherein the second PLC controller repeats the alarm signal if the line dialed by the mobile telephone in case of an alarm, is busy; and

wherein each time the second PLC controller repeats the alarm signal, the third, fourth and fifth PLC controllers activate the mobile telephone and the digital recording device.

2. A security system as claimed in claim 1, wherein the data set comprises a start signal, the at least one emergency number, and the at least one emergency message.

3. A security system as claimed in claim 1, wherein each of the controllers includes inputs and outputs, and wherein the outputs of the first PLC controller are connected to an input of the second PLC controller and of the fifth PLC controller, outputs of the second PLC controller are connected to inputs of the third, fourth, and fifth PLC controllers, outputs of the third and fourth PLC controllers are connected to an input of the mobile telephone, and outputs of the fifth PLC controller are connected to the recording device.

4. A security system as claimed in claim 1, wherein the fifth PLC controller is configured and arranged to control the ignition and the solenoid of the fuel pump of a vehicle.

5. A method of using a security system comprising the steps of:

providing a security system as claimed in claim 1;

positioning the security system inside a security case, the security case including

an underside having at least one switching element for triggering the alarm and at least one switching element for releasing the power supply;

a satellite communications device connected to the security system and having an antenna for communicating with a satellite locating system; and

operating the security system for locating vehicles.

6. The method of claim 5, wherein when the security case is not in contact with a surface, the at least one switching element for the triggering the alarm triggers the alarm and the at least one switching element for releasing the power supply connects the power supply to at least one of the PLC controllers.

7. A method for operating a security system comprising the steps of:

providing a security system as claimed in claim 1;

entering the alarm signal and the alarm information in the PLC controllers into the mobile telephone and digital recording device, which establishes a data set;

activating the operating status via the main relay by means of the remote control;

generating an alarm signal via the at least one sensor of the sensor unit;

transmitting the alarm signal to the first PLC controller, and from the first PLC controller to the second PLC controller;

transmitting the alarm signal at least once to the third, fourth, and fifth PLC controllers, the outputs of which are used to control the mobile telephone and the recording device; and

transmitting the data set via the mobile telephone, wherein the data set is compiled from the at least one emergency number stored in the mobile telephone, the emergency message stored in the recording device, and start and initialization signals from the third and fourth PLC controllers.

8. A method as claimed in claim 7, further comprising the steps of:

operably connecting the security system to a vehicle having an ignition power supply and a fuel pump solenoid;

interrupting the vehicle ignition power supply; and

blocking the fuel pump solenoid.

9. A method as claimed in claim 7, further comprising the step of:

repeating the alarm signal in the second PLC controller at least once if the line dialed in case of an alarm by the mobile telephone is busy, to cause the line to be redialed.

10. A method as claimed in claim 7, further comprising the steps of:

operably connecting the security system to a vehicle having a power supply;

supplying the security system with power via the vehicle power supply, except for the remote control that is operated externally and with a battery.
