Abstract
The present invention is directed to a system and method for accessing home monitoring devices remotely via a distributed wide-area network (WAN). More specifically, the present invention is directed towards smoke detector system, which monitors for the presence of smoke and communicates the smoke condition to a remote location. The smoke detection system comprises a smoke detection device connected to a communication device. The smoke detection device outputs a signal or a change in a signal upon detection of smoke. This signal or change in signal is monitored by the communication device. The smoke condition is then communicated to the remote central location via a message system.
Claims12
A smoke detector comprising:
- a smoke sensor sensing a smoke condition and outputting an alarm signal upon detecting a smoke condition;
- an alarm, connected to the smoke sensor, indicating a smoke condition upon detection of the alarm signal;
- a communication device, connected to the smoke sensor, receiving the alarm signal and wirelessly transmitting an indicator of the smoke condition in a predetermined message format to a remote monitoring device upon detection of the alarm signal, each communication device having a unique address;
- wherein the smoke sensor is a photodetection smoke sensor;
- wherein the alarm is an audible alarm;
- and
- wherein the predetermined message format comprises at least one packet, wherein the packet comprises:
- a receiver address comprising a scalable address of the at least one of the intended receiving communication device;
- a sender address comprising the address of the sending communication device;
- a command indicator comprising a command code;
- at least one data value comprising a scalable message;
- and
- an error detector that is a redundancy check error detector.
A smoke detector comprising:
- a smoke sensor sensing a smoke condition and outputting an alarm signal upon detecting a smoke condition;
- an alarm, connected to the smoke sensor, indicating a smoke condition upon detection of the alarm signal;
- and
- a communication device, connected to the smoke sensor, receiving the alarm signal and wirelessly transmitting an indicator of the smoke condition in a predetermined message format to a remote monitoring device upon detection of the alarm signal, each communication device having an unique address;
- wherein the smoke sensor is a photodetection smoke sensor;
- wherein the alarm is an audible alarm;
- wherein the predetermined message format comprises at least one packet, wherein the packet comprises:
- a receiver address comprising a scalable address of the at least one of the intended receiving communication device;
- a sender address comprising the address of the sending communication device;
- a command indicator comprising a command code;
- at least one data value comprising a scalable message;
- and
- an error detector that is a redundancy check error detector;
- wherein the packet further comprises:
- a packet length indicator which indicates a total number of bytes in the current packet;
- a total packet indicator which indicates the total number of packets in the current message;
- a current packet indicator which indicates which packet of the total packets the current packet is;
- and
- a message number, wherein the controller generates a sender message in the preformatted command message and the transceiver generate a response message number formed by a mathematical combination of the sender message number and a predetermined offset.
