First Claim
1. An entrance intercom system, fabricated on the gate of a community, providing the functions of communicating between visitors and residents, identity recognizing, locking/unlocking the gate, said entrance intercom system comprising:
- a data base, storing the resident codes, the phone numbers and the identity recognizing codes of the residents of the community;
a communication module, coupled with public switch telephone networks, providing the communicating function between the visitors and the residents, and receiving the incoming phone calls;
a CPU, connected with said data base and said communication module respectively, responsive to the resident codes input by the visitors via a dialing keyboard, to select the phone numbers of the resident stored in said data base, and to drive said communication module automatically to dial the resident for providing the communicating function between the visitors and the resident;
an incoming phone numbers collecting module, connected with said communication module and said CPU respectively, collecting the incoming phone numbers, said CPU can compare said incoming phone numbers and the phone numbers of the residents stored in said data base, when the incoming phone number is identical to one of the phone numbers of the residents in said data base, said CPU will send a signal to unlock said gate;
a RF identification device, for detecting the RF messages of identity recognizing and sending to said CPU, said CPU can compare said RF messages with said identity recognizing codes stored in said data base, when said RF message is identical to that of the resident in said data base, said CPU will send a signal to unlock said gate; and
a remote control receiving means, for receiving remote control messages of identity recognizing and sending to said CPU, said CPU can compare said remote control messages with the identity recognizing codes stored in said data base, when the remote control message is identical to one of the identity recognizing codes of the residents, said CPU will send a signal to unlock said gate.

Abstract
An entrance intercom system comprises the following elements. A data base is applied to store the resident codes, the phone numbers and the identity recognizing codes of the residents. A communication module is coupled with public switch telephone networks to provide the communicating function between the visitors and the residents, and to receive the incoming phone calls. A CPU responsive to the resident codes input by the visitors can select the phone numbers of the resident stored in the database, and drive the communication module automatically to phone the resident. An incoming phone numbers collecting module is applied to collect the incoming phone numbers. The CPU can compare the incoming phone numbers and the numbers stored in the database. When the incoming phone number is identical to one stored in the data base, the CPU can unlock the gate.
