Embodiment 1

[0033] Embodiment 1: Step 1. The outdoor station sends an Ethernet communication protocol packet to each IP address of the LAN network segment every 1 second, and the outdoor station performs the operation of detecting whether the outdoor station and the indoor station are in the networking state at this time. The fields of the encapsulation format of the Ethernet communication protocol package are respectively: the Ethernet communication protocol package of the type of heartbeat data packet, connection, outdoor station equipment, Req request, connection; waiting for the response of the indoor unit corresponding to each IP, and sending each Add 1 to the statistics field of the data structure in the array corresponding to each IP;

[0034] Step 2. When the indoor unit corresponding to the IP (192.168.1.165) does not respond for more than 3 seconds, the indoor unit corresponding to the IP (192.168.1.165) is not connected. At this time, the data structure corresponding to the IP (...

Embodiment 2

[0036] Embodiment 2: Step 1, the outdoor station sends an Ethernet communication protocol packet to each IP address of the LAN segment every 1 second, and the outdoor station performs the mutual state interaction operation between the outdoor station and the indoor station at this time, then the Ethernet The fields of the communication protocol packet encapsulation format are: Ethernet communication protocol packet, voice, outdoor station equipment, Req request, voice of the instruction data packet type; waiting for the response of the indoor unit corresponding to each IP, and corresponding to each IP Add 1 to the statistics field of the data structure in the array;

[0037] Step 2. When the indoor unit corresponding to the IP (192.168.1.185) responds within 1 second, it means that the indoor unit corresponding to the IP (192.168.1.185) has made voice, and then connect the indoor unit corresponding to the IP (192.168.1.185) to The status is sent to the VTO through the Ethernet...

Embodiment 3

[0039] Embodiment 3: This embodiment is based on Embodiment 2. In step 1, the door station performs the query command operation in the second second, and then sends an Ethernet communication protocol packet to each IP address of the LAN segment, and its door At this time, the outdoor station and the indoor station perform the mutual state interaction operation, and the fields of the Ethernet communication protocol packet encapsulation format are: the Ethernet communication protocol packet of the command data packet type, query, outdoor station equipment, Req request, voice ; Wait for the response from the indoor unit corresponding to each IP, and add 1 to the statistics field of the data structure in the array corresponding to each IP;

[0040]Step 2. If the indoor unit corresponding to the IP (192.168.1.185) responds within 1 second, it means that the indoor unit corresponding to the IP (192.168.1.185) has made voice calls, and the indoor unit corresponding to the IP (192.168....

Abstract

The invention provides a method for finishing the communication between a door phone and inner phones based on an Ethernet communication protocol, which comprises the following steps: a group with 256 elements is defined in a door phone memory, each element corresponds to one IP (Internet Protocol) of a network segment of a local area network, each IP corresponds one inner phone, and a data structure is defined; the door phone transmits an Ethernet communication protocol packet to each IP address of the network segment of the local area network within one period time, and the Ethernet communication protocol packet is packaged by a self-defined format; and the door phone packages the operation to be carried out at the moment in the protocol packet and is communicated with the inner phone, and the states of the door phone and all the terminal inner phones are marked by all fields of the data structure of the door phone according to the communication situation. Therefore, the effect that one door phone systematically calculates, manages and monitors the inner phones of each terminal is realized; and equipment of the door phone and the inner phones have quick data transmission speed and low bit error rate by means of the Ethernet communication protocol packet, and the functions of unlocking, monitoring, talkback and reporting of the door phone and the inner phones can be realized.

Description

【Technical field】 [0001] The invention relates to the technical field of security products based on Ethernet communication, in particular to a communication method for an outdoor station and an indoor station based on an Ethernet communication protocol. 【Background technique】 [0002] With the advent of the 21st century, our society is in an era of information revolution and knowledge economy. Our country's economy is developing rapidly. In addition to meeting people's basic living requirements, houses must also meet entertainment, meeting guests, and office work. At the same time, people have put forward higher requirements for the comfort, safety and convenience of life. For a residential complex, the safety of residents is the first priority. Generally, two indoor intercom extensions are installed in each household in the community, and one outdoor station is installed at the door. When a visitor calls, the user can judge through the visual screen of the indoor station. ...
