- Security means for providing information transmission with a security function 15 5 b Server 2 consisting of 5 b, remote monitoring center 1 2 General public line 3 Low communication cost public line network 3 Low communication cost public line to connect to 1 Interface means 1 2b, high-speed digital line interface means 1 3b for connecting the remote monitoring center 2 to the high-speed digital circuit network 32 of the general public line 3, general-purpose terminals 24 consisting of general-purpose personal computers, etc. And a dedicated network 25 for connecting the server 21 and the general-purpose terminal 24.
- Fig. 2 shows the types of information transmitted on each network.
- the general public line 3 is physically a single electric wire, but there are a plurality of types of communication networks that perform communication using the electric wire. Therefore, the most appropriate network is allocated from among multiple types of network according to the degree of security of the information to be transmitted. For example, although failure information, image information, and audio information from elevators have a large data transmission volume, security functions are not so important. Therefore, V P N or A D
- the data be transmitted using a high-speed, large-capacity high-speed digital network 32 using SL or the like.
- security functions such as encryption means and authentication means are added to a low-cost public line network 31 such as an analog line with low communication cost or ISDN is suitable.
- the optimal network according to the information to be transmitted is selected by the network selecting means 14a and 14b.
- FIG. 3 is a schematic flowchart showing the operation of the remote monitoring center 2 when transmitting information.

Also, in the network selection means 14b of the remote monitoring center 2, if the information to be transmitted is large-capacity information such as image information and voice information, the high-speed digital network 32 is selected.
- a low communication cost fixed line network 31 with an encryption function and a verification function is added in the same way as the above control commands.
- the information may be transmitted in such a manner.
- the information may be transmitted in such a manner that the transmission procedure and the reception procedure are exchanged between the remote monitoring center 12 and the elevator 1.
- the specific code may be set when the elevator 1 is shipped, or may be set after a maintenance contract is concluded.
- the content of the specific code may be a MAC (Media Access Control) address, an IP (Intemet Protocol) address, a unique access number, etc. for each elevator 1 so as not to be leaked to a third party.
- an optimum communication time is determined according to the security level of information to be transmitted.
