Problems solved by technology

[0035] However, this is difficult to achieve in reality
Regardless of each home bus system, in each home, not only the communication device, but also the equipment contained or occupied by it will be added and deleted again and again, and it is impossible to know exactly one by one.

Embodiment 1

[0102] In this embodiment, when each machine sends a message or necessary information to machines in other networks, it always sends the communication information from multiple routers connected to its own network to a specific router, and it is analyzed and processed correctly in this specific router. communication path.

[0103] Image 6 (a) shows an example of the structure of an address in this embodiment, and (b) shows an example of a structure of a message. In addition, the node addresses of the source and receiver shown in (a) are SNA and DNA in (b). It is evident from this figure that the Figure 4 The shown application software and the address structure processed within the communication intermediate device are used as a machine ID consisting of a network ID and a machine ID within the network.

[0104] In addition, if Image 6 As shown in (b), this address information is placed in the data area of ​​a message sent and received on the network, and is used as a mes...

Embodiment 2

[0120] In this embodiment, each router notifies the machine of the receiving address of the message from the machine that constitutes the best route and is the machine on the network to which the machine belongs as the sending party for the query of the sending party of the message from the machine.

[0121] In the previous embodiment 1, once each machine sends the message itself to a specific router on the network, when loading a new network or router, according to the situation and message information of the entire machine sending messages to machines connected to other networks amount, the processing load on that particular router increases. Thus, the difference in this embodiment is that each machine sends the message itself directly to the most suitable machine (and router).

[0122] Figure 10 (a) shows the structure of each machine of this embodiment. In the figure, 411 is the message body making part in the application program processing part. 421 is a destination n...

Embodiment 3

[0136] This embodiment relates to directly or indirectly supplying information of a planned route to each machine in advance.

[0137] The purpose of the home bus system is limited to providing comfortable life and security, saving energy, etc., and it also naturally limits the types of machines related to each purpose and their sub-networks.

[0138] Specifically, there are difficulties in price and available communication devices in placing the desk lamp on the router, and there are limitations on the destinations for sending the operating status. It has nothing to do with washing machines, temperature sensors, gas sensors, etc.

[0139] The sending destination of the gas sensor is also directly related to the exhaust fan and other safety-related equipment. Although it is possible to indirectly display warnings to the family on the TV receiver and notify the management center by phone, it will not be considered first to make it in the final stage. Notify fax machines and wa...

Abstract

In a home bus system in which a multiplicity of networks each having a multiplicity of appliances connected thereto are connected one another, information is easily exchanged between appliances over different networks. An address configuration that is processed in application software and communication middleware has a network ID and a network appliance ID. On each network, there is provided a particular router having information about all the connections of other networks than the each network. Under this configuration, an appliance transmits a message directed to another network, only to a particular router and the particular router establishes an appropriate route for transmission, as considering the actual states of the networks.

Description

technical field [0001] The present invention relates to a home network, and more particularly, to a communication protocol and processing for correctly transmitting data from each device installed in a home network to devices installed in another network. Background technique [0002] Recently, many and various machines are used in each home, each building, each floor and area of ​​each building. Thus, attempts to obtain a better living environment, working environment, energy saving, and work efficiency by comprehensively managing these machines by a home network (ie, a home bus system) continue. [0003] Specifically, for example, air conditioners, refrigerators, electric fans, bath heaters using solar energy, microwave ovens, water heaters, electric kotatsu, air heaters, electronic clocks, television receivers, lighting equipment, etc. are used in various households. Time, period, etc. have a great relationship with each other, and it is possible to improve the living en...
