Abstract
Information in the form of redundant message packets is sent between a remote device and a host device, e.g., a wireless security system. In order to conserve energy, the frequency of trigger events in the remote device is determined, and the number of redundant message packets sent is based on the determined frequency.
Claims25
A method of sending information in the form of redundant message packets between a remote device and a host device, said method comprising:
- determining a frequency of trigger events in the remote device;
- and
- regulating a rate of redundant message packets based on the determined frequency.
An apparatus for managing the transmission of message packets from a remote device to a host device, said apparatus comprising:
- a first component for measuring a frequency of successive input signals received from an external source;
- and
- a second component, connected to said first component, for varying a quantity of message packets sent from the remote device to the host device based on the frequency measured by said first component.
A remote device for use in a security system, said remote device comprising:
- a depletable power source;
- a sensor responsive to security trigger events;
- a transmitter connected to send redundant trigger event data packets to a host device in response to the security trigger events;
- and
- a regulator connected to control the transmitter to vary a rate at which the redundant trigger event data packets are sent based on a rate at which security trigger events occur.
A method for transmitting messages from a remote sensing device to a system controller in a security system, the method comprising the steps of:
- sending a series of redundant messages from the remote sensing device to the system controller in response to a trigger event sensed by the remote sensing device;
- determining a frequency of occurrence of the sensed trigger event;
- and
- selecting a quantity of the redundant messages sent by the remote sensing device to the system controller based on the determined frequency.
A security sensing device comprising:
- a sensor for sensing a trigger event indicative of a security condition;
- a transmitter for transmitting a series of redundant messages in response to the trigger event;
- a controller for controlling the number of redundant messages transmitted by the transmitter based on a frequency of occurrence of the sensed trigger event.
