Field: Handling (Mechanical engineering)
Classification: CPC B | IPC B

Claim 3:
4. An elevator control device being connected with a remote monitoring server that remotely monitors an elevator, via a communication network, the elevator control device comprising:
a processor that performs a monitoring control process for monitoring the elevator; and
a memory that stores a communication function in which a control program for communicating with the remote monitoring server for the elevator is stored, a remote monitoring function in which a control program for the monitoring control process is stored, and a maintenance terminal function in which a control program for connection with a maintenance terminal is stored, wherein:
the remote monitoring function is encrypted and is stored in the memory, and
the processor is configured to:
receive a decryption key of the remote monitoring function from the remote monitoring server by using the communication function;
decrypt the remote monitoring function by using the decryption key; and
execute the monitoring control process,
wherein:
the elevator control device includes a maintenance terminal connector for connecting the maintenance terminal,
the maintenance terminal function is stored in the memory without being encrypted, and
in a case where a continuous connection time in which the maintenance terminal is continuously connected reaches a designated connection time that is in advance designated, the processor is configured to execute a communication restriction process for restricting communication with the maintenance terminal.
