The specific embodiment

Below, referring to figs. 1 through Fig. 5 one embodiment of the invention is described.

At first, Fig. 1 for example is the schematic diagram of situation about communicating as getting off: off-premises station main frame 1 has carried the microcomputer M that comprises communication table of the present invention, comprise a plurality of COM1 a, b, c, on these COM1s, be connected with communication network A, B, C, on communication network A, be connected with

indoor set

2,3,4, on communication network B, be connected with off-

premises station handset

5,6,7, the service aid 10 that uses when being connected with Long-Range Surveillance Unit 8, personal computer 9, attendant on the communication network C etc. at maintenance activity.

In addition, though not shown, indoor set 2～4 or off-premises station handset 5～7 etc. are also same with off-premises station main frame 1, comprise a plurality of COM1s, also comprise include with communication network that each COM1 is connected respectively on the table of information such as address of the device that connects.

This table can preestablish and comprise, also can generate by communication.If on the communication network that connects on which COM1, connect which kind of device determine, the method that then preestablishes above-mentioned table concerning the personnel that construct etc., can not be confused about which device is connected to where better, very easy.In addition, even less set, and the table that generates by communication, in the form of the transmitting and receiving data that communicates, also comprise sender address and recipient address at least, and each device is in order to judge that whether the transmission data of sending are the transmission data at oneself, temporary transient all transmission data that receive, if therefore on above-mentioned COM1, connect communication network, the device that connects on this communication network begins communication, then can judge the device that on which address, has connected which kind of machine, thereby, also can generate above-mentioned table by sending the communication that receives on the communication network of confirming to connect on the COM1.

Moreover this table can be 1 table that has gathered all COM1s that microcomputer M has, and also can be the table that each COM1 is gathered respectively.If the table that off-premises station main frame 1 comprises is 1 table that has gathered all COM1s, be convenient to understand the ground diagram, then for example as shown in Figure 2, be the COM1 20 that connection is shown, the machine 21 that connects and the such table 23 of list of address 22; And if the table that off-premises station main frame 1 comprises is the table that each COM1 is gathered respectively, be convenient to understand the ground diagram, then for example as shown in Figure 3, be the machine 21 that each COM1 a, b, the last connection of c only are shown, such table 24～26 of list that reach address 22.

For example, in the communication network A of Fig. 1, carry out the communication between indoor and outdoor machine; In communication network B, carry out the master-son communication between the off-premises station; In communication network C, carry out Stateful Inspection communication from Long-Range Surveillance Unit 8, personal computer 9 or service aid 10.

The communication of carrying out on each communication network has: the certain hour every tens of seconds sends the periodic communication of reception; The urgency communication that when generation is unusual, carries out; Or from the request of data of certain device and the data transmission corresponding etc. with it.

Here, for example suppose that operation communication net C goes up the Long-Range Surveillance Unit 8 that connects, be used to monitor the request of data of the operating condition of indoor set 2, then at first, as shown in Figure 2, it is 08 of Long-Range Surveillance Unit 8 that Long-Range Surveillance Unit 8 makes sender address, and making the recipient address is 02 of indoor set 2, the classification sign indicating number 20 of additional representation request of data constitutes the transmission data, sends to off-premises station main frame 1 by communication network C.

Receive off-premises station main frame 1 from the transmission of this Long-Range Surveillance Unit 8 according to built-in table 23, confirm that indoor set 2 is connected COM1 a and goes up on the communication network A that connects, will send to communication network A from COM1 a from the request of data that Long-Range Surveillance Unit 8 sends.

Equally, personal computer 9 that communication network C upward connects and service aid 10 also receive the transmission from Long-Range Surveillance Unit 8, it oneself is not indoor set 2 that but personal computer 9 and service aid 10 are judged, and in built-in respectively table, do not login the address 02 of indoor set 2, so the temporary transient transmission data that send from Long-Range Surveillance Unit 8 that send of the COM1 beyond the COM1 that is connected with communication network C.But the communication network beyond the communication network C does not exist, and does not reply certainly yet, sends to indoor set 2 so identify from Long-Range Surveillance Unit 8, but ignores it, does not carry out replying or new transmit operation off-premises station main frame 1.

Receiving indoor set 2 from the transmission of off-premises station main frame 1, to make sender address be 02 of indoor set 2, make the recipient address be carried out request of data Long-Range Surveillance Unit 8 08, constitute reply data with the classification sign indicating number 21 of replying of the request of data of representing to send and the data of replying, send to off-premises station main frame 1 by communication network A.

At this moment, same with the explanation of above-mentioned communication network C, this communication network A goes up indoor set 3 and the 4 temporary transient transmissions that receive from this off-premises station main frame 1 that connect, but can really admit a fault at the transmission data of oneself by enough built-in tables, and on the communication network A that these transmission data send to, there is indoor set 2, so ignore it as the recipient.

When the indoor set 2 that connects from this communication network A has sent reply data too, the reply data of indoor set 2 is ignored by indoor set 3 and 4, have only off-premises station main frame 1 to receive it, select COM1 c according to table 23, send to Long-Range Surveillance Unit 8 by communication network C, the Long-Range Surveillance Unit 8 that communication network C go up to connect and communication network A go up the communication that the indoor set 2 that is connected carries out and just do not communicate and can finish to the communication network B that has nothing to do that communicates by letter with this on a plurality of communication networks.

Like this, by in the built-in microcomputer of each device, comprising the contents table that records the device that connects on each communication network that connects on each COM1, can be chosen in the communication path that sends reception on a plurality of communication networks, so can relax the crowded of communication on each communication network, the relaying that the device that has only signal post to need carries out this communication is so also can alleviate the burden of the device that has nothing to do of communicate by letter with this.

In addition, for example as shown in Figure 4, suppose on the COM1 d of the microcomputer m that carries on the indoor set 2 of aircondition shown in Figure 1, exist with COM1 e that off-premises station main frame 1 grade communicates on the communication network A communication network D that is connected with remote control 11 in addition that is connected, then this remote control 11 only communicates with indoor set 2 usually, it or not the device of direct-connected communication network A, B on the off-premises station main frame 1, the last setting of C, so off-premises station main frame 1 is not mentionleted alone and is signed in in the built-in table 23, even the existence of remote control 11 can not be discerned.

Under this state, with above-mentioned same, under the situation of the request of data of the operating condition of carrying out this remote control 11 from Long-Range Surveillance Unit 8, to make the recipient address from Long-Range Surveillance Unit 8 is after the transmission data of remote control 11 send to communication network C, with above-mentioned same, this communication network C goes up the personal computer 9 of connection and the transmission data that service aid 10 receives from Long-Range Surveillance Unit 8, identify and do not login remote control 11 in the information of in built-in respectively table, logining, COM1 beyond the COM1 that is connected with communication network C sends the transmission data from Long-Range Surveillance Unit 8, but do not reply, so only identify the transmission data that have or not Long-Range Surveillance Unit 8.

Off-premises station main frame 1 also receives the transmission data from this Long-Range Surveillance Unit 8, confirm the login of remote control 11 with built-in table 23, but do not exist, so COM1 a beyond the COM1 c that is connected with communication network C and b send transmission data from Long-Range Surveillance Unit 8 to communication network A, B.

Communication network B goes up off-premises station 5～7 temporary transient transmission data of sending here via off-premises station main frame 1 from Long-Range Surveillance Unit 8 that receive that connect, but it is same with above-mentioned personal computer 9 or service aid 10, do not login remote control 11 in the table, the communication network that sends to beyond the communication network B is not replied yet, so only identify the transmission data from Long-Range Surveillance Unit 8.

In addition, the last indoor set 3 and 4 that connects of communication network A too.

On the contrary, indoor set 2 that communication network A go up to connect, that directly be connected with remote control 11 will send to remote control 11 from the data request signal from Long-Range Surveillance Unit 8 that off-premises station main frame 1 sends, remote control 11 generate with from the corresponding reply data of the request of data of Long-Range Surveillance Unit 8, making the recipient address is 08 of Long-Range Surveillance Unit 8, making sender address is 11 of remote control 11, sends to indoor set 2.

Indoor set 2 receives the reply data of replying from above-mentioned remote control 11, replys off-premises station main frame 1 by communication network A.

Off-premises station main frame 1 is confirmed to send the reply data of remote control 11 from communication network A, think that remote control 11 is present on some communication networks relevant with communication network A, in table 23, add the information such as address of remote control 11, and affirmation is Long-Range Surveillance Units 8 from the receiving terminal of the transmission data that communication network A sends, be present in as known from Table 23 on the communication network C, go up the communication network C that connects so send to COM1 c, the above-mentioned reply data that Long-Range Surveillance Unit 8 receives from remote control 11 is finished the communication from above-mentioned Long-Range Surveillance Unit 8 to the request of data of remote control 11.

By communicating by letter of this Long-Range Surveillance Unit 8 and remote control 11, off-premises station main frame 1 has been logined remote control 11 and has been present on the communication network relevant with communication network A on table 23, so in communication thereafter, via off-premises station main frame 1 when remote control 11 communicates, do not send to communication network B, and only communicate to communication network A.

As mentioned above, illustrated by off-premises station main frame 1 relaying, the example of the communication of on direct-connected communication network on the off-premises station main frame 1, carrying out, with extend to off-premises station main frame 1 on the example of communicating by letter of direct-connected communication network not, connecting a plurality of communication networks, in the communication of on each communication network, carrying out, by the built-in device that connects on above-mentioned each communication network of including in the microcomputer in the device of the relaying that carries out this communication, or the table of the information such as address of the device that connects on other communication networks relevant with this communication network, can select and the relevant communication network of transmission data that sends from some devices, so alleviated the communications burden that communicate by letter with this irrelevant communication network and device are applied.

Then, for example as shown in Figure 5, in each device that exists on direct-connected communication network A, B, the C on off-premises station main frame 1, Long-Range Surveillance Unit 8 is moved from communication network C under the situation about being set on the communication network A, certainly, not having transmit leg on communication network C is the transmission data of Long-Range Surveillance Unit 8.

At this moment, off-premises station main frame 1 usually as mentioned above, at least carry out periodic communication every tens of seconds certain hours at interval, in substantially exceeding several minutes of this certain hour, communication can not interrupted, so after this was with the time that is divided into unit, it was deleted from communication network C to judge Long-Range Surveillance Unit 8; Perhaps through above-mentioned with the time that is divided into unit after, as the deleted final affirmation of Long-Range Surveillance Unit 8, carry out transmission from COM1 c to communication network C at Long-Range Surveillance Unit 8, confirm still not that from the replying of Long-Range Surveillance Unit 8 this Long-Range Surveillance Unit 8 of deletion includes content from table 23.

In addition, the communication of the sender address of non-existent Long-Range Surveillance Unit 8 on communication network A before existence on the communication network A has, so after the communication of confirming the sender address on this communication network A with Long-Range Surveillance Unit 8, perhaps, it is the transmission of Long-Range Surveillance Unit 8 that the communication network A that connects from the COM1 a of off-premises station main frame 1 makes the recipient, after confirming its response, sign in in the above-mentioned table 23.

Here, as mentioned above, for deletion in the above-mentioned table and interpolation, communicating the method for confirming to the device of this deletion or interpolation is best judgement, but as additive method, as mentioned above, by carrying out periodic communication confirmed to have or not this periodic communication at interval with tens of seconds at least, can judge interpolation or deletion on this communication network.

Like this, existence by direct-connected device on the communication network of confirming to connect on each COM1 or confirm transmission data from said apparatus, also can identify from before deleted or added new device on the communication network of existence to communication network, can from above-mentioned table 23, delete or in above-mentioned table 23, add, no matter which communication network device is connected on, can both carry out communication thereafter.

In the present embodiment, the device that the relaying that has a plurality of COM1s, connects different communication networks respectively on this each COM1, communicate between this communication network has been described is an off-premises station main frame 1, but the device beyond the above-mentioned off-premises station main frame 1 also is the device that comprises a plurality of COM1s, so be not limited to this, also can change the structure of communication network, carry out relaying by other devices.

In addition, illustrated that above-mentioned off-premises station main frame 1 built-in table is microcomputer M and the built-in table of m, but be not limited to this that carry microcomputer or memory beyond microcomputer M and m, it is also no problem to make it store or handle.

As mentioned above, have a plurality of communication networks, in the device that on these a plurality of communication networks, communicates, preparation illustrates the table of the device that connects on this communication network, communicate according to this communication path of showing to select to lead to the communication network that is connected with the communications reception end device, thereby alleviate the communication network that other do not communicate, reach the burden of communication being carried out the device of relaying, the connection of the device that connects on above-mentioned communication network is added, deletion waits under the situation of change, discern according to having or not the transmission data that send to above-mentioned communication network, rewriting above-mentioned table changes, thereby reselect the new communication network that signal post needs according to the table that this has changed, thereby no matter which communication network device be connected on and can both communicate.
