Abstract

A danger alert device (M) includes a sensor for a danger parameter, evaluation electronics for evaluating sensor signals, a memory for storing alarm data, and a communication interface (K) for the wireless communication of the danger alert device (M) with a remote operator control module (H). The communication interface (K) is designed for communication in the radio-frequency range, preferably in accordance with the Bluetooth standard, or in the infrared range, preferably in accordance with the IrDA standard, and comprises corresponding transmission and receiving means. The operator control module (H) is formed by a remote control or a computer of a PC, laptop or hand-held type and has an analog communication interface (K′).

Claims

1. A danger alert device comprising a sensor for sensing a danger parameter, evaluation electronics for evaluating signals from the sensor, a memory for storing alarm data, and a communication interface by which the device communicates with a remote operator control module, wherein the communication interface is designed for wireless communication and comprises transmission and receiving means.

2. The device according to claim 1, wherein the communication interface is designed for communication in the radio-frequency range, or in the infrared range, and is formed by a transceiver or by a separate transmitter and receiver.

3. The device according to claim 2, wherein the sensor is designed to detect heat radiation and receives infrared radiation through a window in a housing of the alert device, with the transceiver, or transmitter and receiver, forming the communication interface being disposed behind the window.

4. The device according to claim 3, further comprising a sabotage detector having comprising an infrared transmitter and an infrared receiver, and wherein the infrared transmitter or the infrared receiver is formed by an IrDA transceiver, or IrDA transmitter and IrDA receiver, which forms the communication interface.

13. The device according to claim 2, wherein the radio frequency range is in accordance with a Bluetooth standard.

14. The device according to claim 2, wherein the infrared range is in accordance with an IrDA standard.

5. A danger alert system comprising at least one danger alert device, said device comprising a sensor for sensing a danger parameter, evaluation electronics for evaluating sensor signals, a memory for storing alarm data, a communication interface, and further comprising a portable operator control module for wireless communication with at least one danger alert device, said system comprising forming the operator control module by a remote control, or a computer which comprises an analog communication interface, and wherein the two communication interfaces are designed for communication in a radio-frequency or infrared range.

6. A system according to claim 5, further comprising forming each of the communication interfaces by a transceiver or a transmitter and receiver, and effecting the communication between a danger alert device and an operator control module in accordance with the IrDA or the Bluetooth standard.

7. A system according to claim 5, further comprising setting the danger alert device to a data transmission mode through the operator control module.

8. A system according to claim 7, further comprising setting the danger alert device automatically to the data transmission mode when the operator control module is authenticated.

9. A system according to claim 8, further comprising using a code or a cryptological procedure to effect authentication.

10. A system according to claim 7, further comprising transmitting data stored in the danger alert device during the transmission mode to the operator control module.

11. A system according to claims 0.7, 8 and 9, further comprising effecting a parameterization and/or software update of the danger alert device in the data transmission mode.

12. A system according to claim 7, further comprising upon exchange of safety-related data in the transmission mode, dispatching a sabotage message via the danger alert device.

15. The system according to claim 7, wherein the data stored is alarm-related data and/or location images.
