Description

VLAN-ID specification-based building visual access control design method and system

Technical Field

The invention relates to the technical field of building visual access control monitoring network communication, in particular to a building visual access control design method and system based on VLAN-ID specifications.

Background

The present building entrance guard control system belongs to standard equipment of building construction. The building entrance guard control system is generally divided into an entrance guard intercom system and an entrance guard visual intercom system, and the entrance guard design technology researched by the invention belongs to the entrance guard intercom system.

A building entrance guard control system generally comprises a 'doorway machine', a plurality of 'household machines', a building switch and a floor junction machine. The building entrance machine is arranged at the entrance of a unit of a building, the household machine is arranged in each household of the unit, and the building switch is adjacent to the entrance machine and the floor junction machine is adjacent to the household. The building entrance guard control system mainly has the functions of managing the opening of building unit doors, providing door opening modes for a householder/guest, and generally having the functions of password door opening and IC card door opening. The visiting of the guest is generally confirmed by the owner, and the door is opened under the control of the owner. The conventional technology for confirming the identity of the guest comprises voice talkback and visual talkback.

In China, the development of a building access control system passes through three stages, and the three stages are shown in figure 1. The first stage is from 1992 to 1996, and the door access control system in the first stage basically adopts an analog communication control technology; the second stage is 1997 to 2000, and the door access control system basically adopts a digital communication CPU control technology at the stage; in the third stage of 2000, building access control systems basically adopt network communication technology, and the advanced marks are that an embedded operating system and fingerprint and face brushing control technology of access control are adopted.

Throughout the development of building access control systems, in the first stage of the access control system, when one entrance machine is communicated with a plurality of household machines, the analog signal modulation and demodulation technology is adopted in the general situation; the second stage generally adopts a digital bus technology; the third (current) stage of access control system is basically implemented by using switch information conversion technology, as shown in fig. 2. The unit entrance machine is firstly connected to the branch machines on each floor through the building switch, and then is connected to the resident machines of each floor by the branch machines on each floor. Generally, a residential building has several floors, a switch is provided with several ports, one floor has several households, and a splitter at each floor is provided with several branch ports.

As can be seen from fig. 2:

1) when the number of floors is large or the number of residents per floor is large, the number of cables connected to the branch machines on each floor of the building is increased along with the increase of the floors, the cables are in a tower shape, the number of cables at the high part of the building is small (thin), the number of cables at the bottom of the building is large (thick), and as shown in a five-pointed star graph in fig. 2, the construction and wiring of equipment installation are difficult. In addition, the equipment of the building switch and the deconcentrators on each layer increases the system cost on one hand, and the operation and maintenance problems of the access control system can be increased due to the power supply of the switch and the deconcentrators on the other hand.

2) It can still be seen from fig. 2 that each of the dwelling units belongs to a "terminal" device of the building exchange, not a "network" device. With the rapid development of smart homes, when a householder needs new experience and integrates a smart phone and a tablet computer into an access control system, the terminal function of the householder in fig. 2 is difficult to meet the new requirements of the householder, so that the terminal equipment of the householder needs to be developed into network equipment to establish a householder local area network.

3) In the domestic market, an access control system adopting a switch technology is a mainstream technology, and when new services such as fingerprint door opening, Bluetooth door opening, access video recording and the like are developed, the switch access control system in fig. 2 is not careful. There is a need to research a new access control system with an embedded operating system, which has a modern network communication technology between access control devices and can cater to the development of smart homes today.

An effective solution to the problems in the related art has not been proposed yet.

As shown in fig. 3 to 9, a method for designing a visual door access of a building based on VLAN-ID specification according to an embodiment of the present invention includes the following steps:

in this embodiment, as shown in fig. 3, by referring to the virtual local area network VLAN-ID tag of ieee802.1q, the invention implements a "virtual switching" mechanism, so that the building entrance visual intercom control system only needs the "door phone" of one building unit and the "resident phone" devices of a plurality of users;

in the embodiment, according to the RFC894 design specification, multiple indoor smart phones and tablet computers of a resident can interact with visual information of a door phone through WiFi; for this purpose, in a building unit, the unit virtual local area network is divided into a plurality of 'household local area networks' (one household is one network); in the method, an IP address table of each resident terminal device is established in a building entrance machine through a VLAN-ID (two-layer protocol) and IP address (three-layer protocol) association mechanism based on a parameter configuration principle of a VLAN-ID label/house and N IP addresses/house, so that a local area network communication environment is established between each terminal of a resident and the entrance machine, and the resident machine of the resident is immediately developed into gateway (network) equipment from the terminal device.

in this embodiment, the VLAN-ID information tags of each household are used to bind Channel (CH) parameters and video event association attributes of PANs such as ZigBee and LoRa, and the CH sequence numbers of ZigBee, PANID, LoRa, and bluetooth are all associated with VLAN-ID tag information of the household, so that the VLAN-ID plays a role as a link of smart home (community) information management, for example, the modules in fig. 5, such as ZigBee/PAN-1 (home security), LoRa/PAN-2 (water, electricity, gas meter measurement and monitoring), BLE/PAN-3 (home medical care and old care), and the like; the audio-video information of the doorway machine is associated with the VLAN-ID tag, so that the tracing of the building unit image information can be realized.

The functions of each module are as follows:

the household central controller is also connected with a ZigBee/PAN-1 module, a LoRa/PAN-2 module and a BLE/PAN-3 module respectively.

as shown in fig. 5, one household machine is allocated per household. In order to make the resident have better experience effect, the visual intercom between the householder and the guest and the control of the cell gate are all operated on the mobile phone or the tablet computer, such as the WiFi module in fig. 5. Through the 'resident LAN', various entrance guard functions are realized by the APP of the mobile phone/tablet personal computer, and the application experience effect is obviously improved for the resident. Part of the functionality may also be implemented on the household machine alone, such as the second KEY module in fig. 5.

In this embodiment, the virtual switch module includes an upper network port, a horizontal network port, and a lower network port; wherein, several household machines in the same layer are connected in turn through the horizontal network ports of the virtual exchange modules; two adjacent layers are respectively provided with a resident machine which is connected through an upper network port and a lower network port of each virtual exchange module;

In a set of building entrance guard control system, information interaction between a door phone and a resident phone is completely transmitted between the door phone and the resident phone. Sometimes the resident machine is a 'sink end' of information, namely the entrance machine and the resident machine need information intercommunication; the resident machine is sometimes a 'passing end' of the information, namely the resident machine at this time is a transfer station (including longitudinal transfer and transverse transfer) of the information of other resident machines.

In this embodiment, the multi-dimensional digital information of the resident includes one or more of a name of a resident, a courtyard, a building, a unit, a floor, a household, and information of a home intelligent terminal; the household intelligent terminal comprises one or more of a multi-type sensor terminal, an energy consumption metering terminal, a wearable terminal, an intelligent household appliance, an intelligent mobile phone, a tablet personal computer and a camera; the audio-visual information comprises: the system comprises one or more of monitoring function interaction information such as sensor early warning, an energy consumption meter, home care, household appliance monitoring, property management, fingerprint door opening interaction information, IC card door opening interaction information, password door opening interaction information, Bluetooth door opening through a mobile phone, door opening through visual talkback and the like.

Specifically, as shown in fig. 6, in this embodiment, a building visual access control system based on the VLAN-ID specification is implemented, which includes the following three stages:

firstly, carrying out digital processing on building layout of a residential district, carrying out digital processing on six elements (multi-dimensional digital information of residents) such as names, houses, buildings, units, floors and rooms of the residents and building a digital model, and building a virtual local area network and a resident local area network on the building units (modeling and network building preparation stages);

secondly, binding modeling data (multi-dimensional digital information of residents) with VLAN-ID data, configuring a unique VLAN-ID identification symbol for each building resident, associating the identification symbol with data such as virtual exchange, resident information, fingerprint characteristics, mobile phone numbers registered by the residents individually, video information and the like to establish a database, in addition, indirectly defining IP addresses of a plurality of devices such as mobile phones, tablet computers, cameras and the like of each resident by a door phone through the VLAN-ID identification database, establishing a local area network (one user for one network) between the door phone and each resident, and using the data association database as a main basis for the operation of an access control system (a data configuration stage);

and finally, according to the reasonable configuration of VLAN-ID and IP addresses of terminals of each household, under the support of virtual local area network IEEE802.1Q labels (VLAN-ID) and Ethernet RFC894 protocol, information interaction is carried out between the door phone and a plurality of household phones, the novel door control visual intercom function is completed, and the monitoring management function (operation stage) of various smart homes can be realized.

In this embodiment, the specific implementation process includes:

1. building 'six-dimensional' digital building model (first stage/modeling, net building preparation)

A design method of building visual entrance guard based on VLAN-ID specification is constructed for intelligent communities in different cities; various building layouts are varied, so that digital model design is carried out on building houses according to buildings in different communities; the model is to embody six data definitions, which are the contents of names, courtyards, buildings, units, floors, residents and the like, namely, the multi-dimensional digital information of the residents, also called as a six-dimensional digital building model, and the model is composed of 16 bytes in common, and the format of the model is shown in table 1.

Table 1: building house digital modeling format

Such as unequal number of units per building, unequal number of floors per unit, and unequal number of residents per floor. Therefore, the digital building house model is to build a table one-to-one according to the physical distribution of the building. Table 2 illustrates the digitized model data of a four-floor, two-unit, two-household per floor. The householder name can be represented by 4 Chinese characters (2 symbols/character) at most, and other parameters are represented by ASCII codes.

Table 2: building residence digital modeling information

Building a table by digitalizing the physical layout of the building residence and the information of the householder, and expressing the names of the householders and the digitalized contents of the rooms of the householders in the unit by using 16 bytes of data (see table 2), wherein the data is derived from the real layout of the building courtyard, so the data of the table has the basic condition of building a householder local area network.

Building 'no exchange' virtual LAN and 'resident LAN'

A design principle of a building visual entrance guard based on VLAN-ID specification, the design principle of the method of the invention is that firstly, according to IEEE802.1Q specification, a 'virtual switching' component of a household machine is designed, a building virtual local area network VLAN (VitualLocalAreaNet) is built, and equipment such as a building switch and the like is saved; secondly, a 'household local area network' (LAN) (LocalAreaNet) is designed according to a DIX (DEC, Intel, Xerox) Ethernet V2 standard (RFC894), and unequal 'household local area networks' are established in one unit, namely one household and one network. The 'resident local area network' can be used for intervening in a plurality of terminal devices such as smart phones and the like, and the experience effect of the access control system is improved.

Whether the virtual switch or the virtual local area network is realized, the building digital model data is required to be established. Building a 'non-exchange' building virtual local area network and a unit 'resident local area network', and completely using an IEEE802.1Q virtual local area network and an RFC894 Ethernet frame format as references to realize the creation of the invention.

2.1 VLAN frame Format

There are two standards for ethernet MAC frame formats, namely, the DIX (DEC, Intel, Xerox) ethernet v2 standard (RFC894) and the IEEE802.3 standard. Table 3 shows the MAC frame format (de facto standard) of the commonly used ethernet V2.

Table 3: ethernet (RFC894) MAC frame format

Since ethernet frames are transmitted at the link layer, the source and destination MAC addresses are also called link layer addresses (linklayeradaddresses), L2 addresses, two-layer addresses, or hardware addresses. The Type (Type) field indicates what protocol is used by the upper layer. The common protocol type values and the definition specifications of the data field and the FCS field are conventional technical means, and are not described herein.

In this embodiment, a design method for a building visual access control based on the VLAN-ID specification is to add a personality (no switch in the building) condition by using the TCI attribute of the ieee802.1q specification, and establish a building local area network. Then, a plurality of 'household local area networks' are built in the building house according to the conventional Ethernet (RFC894) standard.

As shown in fig. 7, the ieee802.1q (colloquially referred to as DotOneQ) standard adds 4 bytes of Vlan identification information (tag) between "transmission source MAC address" and "category field" in an ethernet data frame; the TPID (tag protocol identifier) value is defined as 0x 8100. The device adopts the TPID value specified by the protocol by default, and the switch determines whether the data frame is attached with the VLAN information based on IEEE802.1Q through the TPID.

The TCI (tag control information) field is divided into three parts of Pri, CFI and VLAN. Pri represents a message priority (also called 1p priority, COS or 1q priority), and cfi (canonical format indicator) represents whether the MAC address is encapsulated in a standard format, usually 0 (standard format), in different transmission media. The VLAN-ID represents the VLAN number to which the message belongs, the value range is usually 0-4095, and in the embodiment, the value range of the VLAN number (ID) is 0-3 fff.

2.2 building "No exchanger" virtual LAN (first stage 1/modeling, lapping preparation)

Building a virtual local area network of building units without switches is completed by relying on IEEE802.1Q standard and newly developed household machine virtual switching parts. The novel building visual intercom control system without the switch and the deconcentrator is completed by judging whether the virtual local area network identification symbol (VLAN-ID) in the IEEE802.1Q is matched with the information of the virtual switching component or not.

As shown in table 2, the upper half represents a one-cell vlan, and the lower half represents a two-cell vlan. Each unit virtual local area network can be provided with a plurality of 'household local area networks', namely one household and one network. The core of the invention is to save devices such as switches and the like in a virtual local area network of a unit building, as shown in figure 3, in order to realize that no switch device exists in the local area network, a hand-in-hand information series household machine is invented in the method of the invention, each household machine is designed with a virtual switching module, as shown in figure 5, the part is in a channel form of one inner channel and three outer channels, wherein the information of the inner channels is interacted with a CPU (central processing unit) of the local machine, and the three outer channels are respectively an upper network port, a lower network port and a transverse network port. The lower port is a data entry, and the format of the received data is shown in the VLAN-ID system specification of the virtual local area network in fig. 7. The resident machine determines whether the received frame information is brought into the inner channel (matching VLAN-ID) or is forwarded to the downstream channel (not matching VLAN-ID) through the upper network port (upper floor) and the transverse network port (local floor) by judging the VLAN-ID of TCI in the IEEE802.1Q frame format. Obviously, the IEEE802.1Q virtual frame format sent by the door phone gradually digests and absorbs through the resident opportunity to complete the one-to-one data exchange between the building door phone and a certain resident phone, and the aim that the building entrance guard visual intercom system has no switch or branching machine is achieved.

2.3 building resident LAN (first stage 2/modeling, preparation for Internet connection)

A design method of a building visual access control based on VLAN-ID specification is a technology for dividing a physical network (unit) into a plurality of (household) logical local area networks according to label control information (TCI) in IEEE802.1Q. A unit household is a broadcast domain (LAN), i.e. a logical subnet, and the household is set as a different "domain" in the building virtual local area network, i.e. a household-to-household domain (one household-to-one network). Therefore, the household machine in the door control visual intercom system is changed from a terminal type to a network type, and a household local area network is built in each household room. The application of various terminals (mobile phones, tablet computers, cameras and the like) of residents can be extended through the network. And the building entrance machine enables the building entrance machine list and a certain household machine to complete data communication at a certain moment through the virtual exchange module of the household machine according to the entrance guard service management requirement.

As shown in fig. 8, the virtual local area network of the building units is implemented based on the ieee802.1q standard protocol. In the figure, a institute 025 building 1 unit of a certain cell is taken as an example, a VLAN-ID technology is utilized, firstly, a virtual local area network of the unit is built, and then, a design flow of expanding a plurality of 'household local area networks' (one household and one network) in one building unit local area network is invented according to the specification of Ethernet (RFC 894).

After the 'household local area network' is established, the household machine is not only a terminal device, but also a network device (gateway) is jumped to; terminal devices such as smart phones, tablet computers and cameras used by residents can be registered on the resident machines through WiFi, the resident machines pass through the unit virtual local area network, and under the unified management of the gate machines, the terminal devices of each household can be reasonably distributed to IP addresses, as shown in table 4. The number of the 'resident local area networks' in one building unit is less than or equal to 120 tentatively at present.

Table 4: household local area network terminal IP address configuration table

Building modeling information is associated with a resident/unit VLAN-ID (second stage/data configuration)

A building visual access control design method based on VLAN-ID specifications includes the steps of firstly, establishing a data table (digital modeling) according to building yard layout, and secondly, establishing a virtual local area network in each unit. The above two points are only necessary conditions before the building entrance guard is implemented without an exchanger, and the operation of the system still needs the generation and configuration of original data.

The function of the invention needs a community information service center (property service center) to calculate two data tables according to the layout of the building courtyard. The association of VLAN-IDs with cell phones, residential phones, and other information is embodied in this table. The VLAN-ID configuration of the resident machine needs the on-site installation of the intelligent mobile phone held by the staff; the configuration of the VLAN-ID of the building entrance machine can be realized by remote downloading of a cell information service center. Software of the community information service center and field installation software of a mobile phone APP are already compiled.

3.1. The dwelling machine is associated with VLAN-ID table (as shown in the field configuration in FIG. 6)

At the initial stage of installation, the resident home machine and the building entrance machine have no basic information of VLAN-ID. The invention can realize that the software of the cell information service center provides the function of building digital modeling. The function will create two data tables (table 5), (table 6) respectively according to the current building layout of the cell and the personal information of the householder (see table 2). Wherein table 5 is for household machine to download information and table 6 is for building door machine.

For example, the cell builds an intelligent community, and the responsible person of the responsible building unit reports the mobile phone number (multiple mobile phones) of the installation staff to the information service center of the science cell, and the center records the mobile phone number. The installer logs on the central server and downloads the "XT-APP" software and the information about the cell phones (table 5).

For example, building buildings are: the building comprises a No. 2 yard, a No. 25 building, 2 units of the building, 4 floors of each unit building and 2 households of each floor. The community information service center will build a data table based on the building layout, table 5 lists the household modeling information for the building 1 unit.

Table 5: information of each resident machine of cell number 2, yard number 25, building number 1 unit

According to the actual room number, the central software allocates parameters such as ' modeling room number, VLAN-ID, ZigBee-CH, BLE-CH ', and the like ', wherein:

in the embodiment, the value range of the VLAN-ID is generally selected from 1-3 FF (12 bits), can be distributed according to the 'flow type' of the whole cell and can also be independently distributed according to units. The VLAN-ID values are described in hexadecimal in table 5, and the numbers will be represented in the virtual local area network identification column in ieee802.1q (see fig. 7).

ZigBee has 16 CH (2.4 Ghz), BLE has 40 CH. Since they share the 2.4Ghz band, in order to prevent the interference of wireless channel, the two are allocated in sequence and in reverse sequence, i.e. the ZigBee-CH number is in positive sequence, and the BLE-CH number is in reverse sequence. And the Pan-ID serial number in the ZigBee-CH is automatically generated in the field installation of the staff.

The installation staff clicks the 'actual room number' column frame (table 5) of the APP software on site (a certain resident) under the support of the mobile phone APP, not only sends the corresponding information of the room to the resident of the user through WiFi, but also stores the information in Flash of the local computer. At this time, the resident has conditions for virtual lan communication and development of a smart community.

3.2 Unit doorway machine is associated with VLAN-ID (remote push in FIG. 6)

The cell information service center establishes a 'household machine and VLAN-ID association table' and associates with VLAN-ID information together with an establishing unit door machine. Different from the household machine association table, columns such as a "house owner fingerprint feature code sequence", "house owner telephone number" (bluetooth door open), "video track code interval sequence number" are added (the fourth column, the fifth column and the sixth column in table 6).

Table 6: information of entrance machine of 25 th building 1 unit of area 2 court (for example)

Wherein:

1) and information such as the actual room number, the modeling room number, the VLAN-ID and the like is obtained by remote pushing of the cell information service center. And each unit entrance machine is configured with a unique number, so that the information of the unit entrance machine is consistent with that of the unit resident machine.

2) The fingerprint characteristic code sequence information of the house owner is acquired by fingerprint on site at a gate machine, after a password is input correctly (the password is different from one house to another and can be different between houses), the fingerprint characteristic code sequence information of the owner can be recorded, the relation between the owner and the house is judged according to the password, and the information is bound with the corresponding VLAN-ID. At most 8 pieces of fingerprint information can be collected and input by each household.

3) The information of the house main telephone number is registered by resident personnel on the resident machine of each house through WiFi, the resident machine associates a plurality of mobile phone telephone numbers with the unique VLAN-ID of the resident machine (see table 5), and the associated information is transmitted to the gate machine. And the gate machine collects all the information of all the households in the unit, forms a unit basic management file and sends the unit basic management file to the community information service center. When the resident opens the door through the Bluetooth mobile phone, the door phone checks the resident room number of the mobile phone number through the VLAN-ID and judges whether to control the opening of the door. The number of telephone number entries per household is not more than 8.

4) The sequence number of the video channel code interval can realize the home security function; in order to trace the images of the persons entering the cell door, the video recording function is added in the doorway machine.

A design method of a building visual entrance guard based on VLAN-ID specification provides five modes of fingerprint door opening, IC card door opening, password door opening, mobile phone Bluetooth door opening, visual talkback door opening and the like. The invention deduces who the door opener is (which family) through the data reference basis condition information (table 7) of different door opening modes, associates the image with the serial number of the video channel code interval, immediately adds a time stamp to the image data and stores the image data in the interval, and achieves the purpose of analyzing and checking the image data.

Table 7: various door opening modes correspond to the video recording storage track code section through VLAN-ID (for example)

In the embodiment, the image information of each building unit can be stored for more than 30 days; the calling and browsing of the information must be approved by the cell information management center.

Therefore, by means of the technical scheme, the building visual access control design method and system based on the VLAN-ID specification comprises the following steps:
