System and method for server based control
A system and method in a building or vehicle for an actuator operation in response to a sensor according to a control logic, the system comprising a router or a gateway communicating with a device associated with the sensor and a device associated with the actuator over in-building or in-vehicle networks, and an external Internet-connected control server associated with the control logic implementing a PID closed linear control loop and communicating with the router over external network for controlling the in-building or in-vehicle phenomenon. The sensor may be a microphone or a camera, and the system may include voice or image processing as part of the control logic. A redundancy is used by using multiple sensors or actuators, or by using multiple data paths over the building or vehicle internal or external communication. The networks may be wired or wireless, and may be BAN, PAN, LAN, WAN, or home networks.
1. A device for use with a single wire pair, the wire pair concurrently carrying Direct Current (DC) power and bi-directional digital data signals that is carried over a frequency band above and distinct from the DC power using Frequency Division Multiplexing (FDM), the device comprising:
a connector for connecting to the wire pair;
a splitter having first, second and third ports, wherein the digital data signal is passed only between the first and second ports, and the DC power signal is passed only between the first and third ports, and wherein the first port is connected to the connector;
a software and a processor for executing the software;
a transceiver coupled between the processor and the second port for transmitting digital data to, and receiving digital data from, the wire pair via the connector;
a sensor for sensing a first phenomenon, the sensor having an output coupled for transmitting to the processor a value responsive to the first phenomenon; and
a single enclosure mountable for housing the connector, the splitter, the processor, and the transceiver,
wherein the transceiver and the processor are coupled to the third port for being powered from the DC power via the connector, and wherein the device is operative to transmit the value to the wire pair via the connector.
2. The device according to claim 1 , further being part of, or connectable to, a network via the wire pair, and wherein the device is addressable in the network using a digital address uniquely identifying the device in the network.
3. The device according to claim 2 , wherein the digital address is a Media Access Control (MAC) layer address that is MAC-48, Extended Unique Identifier (EUI) EUI-48, or EUI-64 address type.
4. The device according to claim 2 , wherein the digital address is a layer 3 address and is static or dynamic Internet Protocol (IP) address that is IPv4 or IPv6 type address.
5. The device according to claim 2 , wherein the digital address is autonomously assigned or is assigned by another device via a communication interface using Dynamic Host Configuration Protocol (DHCP).
6. The device according to claim 1 , further comprising an actuator that affects a second phenomenon in response to an actuator command, the actuator is coupled to the receive actuator command from the processor.
