Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a system for providing a multi-unit data service based on a data transmission protocol of an RS-485 network according to an embodiment of the present invention. Referring to FIG. 1, the multi-unit data service providing system 1 based on the data transmission protocol of an RS-485 network according to an embodiment of the present invention may include at least one generation terminal 100, a main control device 200, Joint entrance terminal 300, the guard terminal 400 may include. However, since the data transmission protocol-based MDU data service providing system 1 of the RS-485 network of FIG. 1 is only one embodiment of the present invention, the present invention is not limitedly interpreted through FIG. 1.

In this case, each component of FIG. 1 is generally connected through a network 200. For example, as shown in FIG. 1, at least one generation terminal 100 may be connected to the main control apparatus 200 through a network. In addition, the main control device 200 may be connected to the common entrance terminal 300 through a network. In addition, the common entrance terminal 300 may be connected to the security terminal 400 through the network.

Here, the network refers to a connection structure capable of exchanging information between respective nodes such as a plurality of terminals and servers. Examples of such a network include RS-485, IP communication, power communication, and 3rd generation partnership (3GPP). Project network, Long Term Evolution (LTE) network, 5th Generation Partnership Project (5GPP) network, World Interoperability for Microwave Access (WIMAX) network, Internet, Local Area Network (LAN), Wireless LAN (Wireless Local Area Network) ), Wide area network (WAN), personal area network (PAN), Bluetooth (Bluetooth) network, NFC network, satellite broadcasting network, analog broadcasting network, DMB (Digital Multimedia Broadcasting) network, and the like.

The at least one generation terminal 100 receives a call signal from a common entrance that is a porch of a common house, transmits a door open control signal in response to the received call signal, transmits a security alarm to the guard room, and calls from the guard room. When receiving a signal may be a terminal for performing a call.

The main control apparatus 200 includes an identifier for identifying a common house, and is located between at least one household and the common entrance, for relaying and controlling signal transmission of each component, and for entering and entering at least one household. When storing and managing access data and receiving a call signal transmitted to at least one generation terminal 100 from a common entrance or guard room, whether the household number included in the call signal is a household number registered in the stored access data. Determining whether or not the call signal is transmitted by determining whether the access signal, including the household number and the household password from the common entrance can be authenticated whether or not match the stored access data.

 The main control apparatus 200 stores and manages at least one household number and a household password, and the common entrance terminal 300 includes an identifier of a common house and a common secret previously stored in the common entrance terminal 300. Number and a pre-stored authentication card number, and the security terminal 400 stores and manages the household number of at least one household of the apartment house managed by the guard room to maintain the main-main infrastructure instead of the main-sub. Can be achieved. That is, it is not dependent on any main device, and works with other components by managing data and receiving the result of authentication or request, but may not be dependent by performing a separate main function separately.

The common entrance terminal 300 is located between the main control device 200 and the security office, transmits a call (call) and a video call to the at least one generation terminal 100 in the common entrance, at least one generation terminal 100 Or door control signal received from the guard room, the door can be controlled, and the number of the apartment house, the password of the apartment house and the authentication card number can be managed.

 When the common entrance terminal 300 receives a call signal for calling the at least one generation terminal 100 from the guard terminal 400, whether the household number of the generation terminal 100 to receive the call signal is a stored household number. It may be determined whether or not, and whether to transfer the call signal to the generation terminal 100 having the generation number according to the confirmation. For example, if an outsider wants to call 1023 in the 103 complex, he or she can check whether the 1023 exists in the 103 complex and attempt to connect. Here, since an outsider may invade, authentication may be further performed using a householder's name of No. 1023 or the like.

 The common entrance terminal 300 controls the door opening of the common entrance, and the door opening is controlled by authenticating the common password and the input password previously stored in the common entrance terminal 300, or in the common entrance terminal 300. The authentication card number read and the authentication card number previously stored in the common entrance terminal 300 may be authenticated and controlled. For example, there may be a common entrance in one complex, such as an apartment, and the common entrance may have a separate password. For example, if the password of the common entrance of apartment 103 is 1234, and the password of 103 103 1004 is 1004, the tenant may use two passwords separately. Alternatively, the common door terminal 300 may use the number of each household and the password as the password of the common door, which may be set differently according to each embodiment, and thus are limited to the above-described embodiment. It is not.

The guard terminal 400 stores and manages the identifier of the multi-family house, performs a call and a call to the generation terminal 100 of the multi-family house managed by the guard room, and performs a call and a call from the common entrance terminal 300. And, when receiving a security alarm from at least one generation terminal 100 may generate an alarm.

The data format of each component including the main control device, the generation terminal, the common entrance terminal, and the security terminal includes a waiting time, a start bit, a data 1, a separator, a data 0, and an end bit, and the end bit is a dummy bit. Bit), the waiting time is high state, start bit is low state, data 1 is high state, separator is low state, data 0 is high state, end bit or dummy bit It may be in a low state. At this time, the data format between each component may mean a communication protocol when each component transmits a command or a request by communicating with each other.

In addition, the communication speed of the multi-unit house data service providing system 1 may be less than 9600bps. The reason is that the normal RS-485 communication transmits data one-to-one or one-to-many to the network, so that the transmission of data may be delayed or lost depending on the communication line status or communication speed. In addition, in case of one-to-many communication, in order to shorten the normal communication time, the communication speed is set to approximately 9600bps, which is not a problem when the communication line is in good condition. In many cases, low-cost communication cables are used to reduce costs. In this case, data transmission is often delayed or lost because the communication speed is relatively faster than the performance of the communication cable.

As a result, no matter how good software or hardware is developed, it cannot be used where a low-cost infrastructure such as an old apartment is built. Therefore, the method of providing a multi-unit house data service according to an embodiment of the present invention is practical in the field. It aims to provide a communication protocol that can communicate what happens without data loss or delays without having to repair and replace the built infrastructure. To do this, first, lower the communication speed so that the specifications with the communication cable are met.

Secondly, the multi-unit house data service providing system 1 may use an interrupt / event scheme to compensate for the reduced communication time. Since the communication speed is set so as to correspond to the communication cable, it can be solved by using an event method without using a normal polling method to compensate for a reduced speed communication time.

In this case, the interrupt method detects a hardware change in hardware and the CPU recognizes an input from the outside, and the polling method detects another input. The polling method constantly reads hardware changes and notices the changes. The interrupt method operates when a specific signal comes in. However, polling moves along a typical program path. Respond by a specific syntax to play a role. For example, if you're waiting for a friend who doesn't know when, and you wait in polling mode, you won't be able to do anything until your friend arrives, but if you wait in an interrupt mode, you'll have to do something until you get an Interrupt Request. same.

Based on the concept of the polling and interrupt scheme described above it will be described how to apply in an embodiment of the present invention.

In general, RS-485 communication has a master and a sub and a slave to transmit data from the master to the slave in order to avoid data collision. ) The same operation is repeated to the next slave sequentially. In this case, a smaller number of slaves is not a problem, but as the number increases, the time becomes long.

For example, if there are 50 slaves, the slaves will have their respective IDs, and even if an actual event occurs in step 1, the slaves will not be able to send data directly to the master. In other words, if the master is polling 2 times, it polls 3 to 50 times and then polls once again, so that the actual data transmission time becomes long. Thus, all privileges are held by the master, so all slaves are passively operated by the master. In this case, when packet information is lengthened by segmenting the information, the total packet transmission time is further increased.

The event method does not distinguish between the master and slave methods separately, and both have a master concept so that the initial devices are all in a standby state (RX mode). When an event occurs in the device (including master-slave), the packet is sent to the desired destination and one-to-one communication is performed.

At this time, if an event occurs in another device at the same time, the problem of packet collision may occur by occupying the communication line at the same time.To compensate for this disadvantage, after checking whether there is a received packet from another device before transmitting the packet, By sending packets, data collisions can be prevented.

Third, the multi-unit house data service providing system 1 may include null in the data format to eliminate an error due to a feedback caused by impedance mismatch of a line for communication of the multi-unit house. . Null indicates that null in a programming language has no value depending on the type of language. The null character is an ASCII character with a value of 0 and can be used mainly as a terminator or delimiter.

For example, if a reflection error occurs and a signal consisting of only data is transmitted and received, an error may occur with respect to data for which no data is sent. In this way, it is possible to prevent the data from being broken by adding a null value without adding any value to the data format. In fact, data corruption in the field is caused by valid data at the back of the packet.To improve this problem, add 4 bits of data (f: End Bit / Dumy Bit (2ms): “Low” state) irrelevant to the actual communication of the packet. Even if a break occurs, the actual data can be made valid.

In this case, the communication network of each component including the main control device, the generation terminal, the common entrance terminal and the guard terminal may be connected to the RS-485 communication line.

An operation driven by each component of the multi-unit house data service providing system 1 according to an exemplary embodiment of the present invention is summarized as follows.

The generation terminal 100 may receive a call from the common entrance terminal 300 to make a voice call or check a visitor image, and have a call function by calling a guard room or receiving a call from the guard room.

The main control device 200 is a device for relaying call, response, and call channels, which are various data of the common entrance terminal 300, the generation terminal 100, and the security terminal 400, and each unique number (ID). It can be prevented from data collision when calling or expanding the other main control device 200.

The main control device 200 is installed between the household terminal 100 and the common entrance terminal 300, and stores the household number and the household password, which are household information, as the household terminal. If the card of the main control device 200 receives the calling information when calling the household or calling the household from the guard terminal 400 of the guard room, the household information is called by comparing whether the household information to be called is a registered household number. It may be determined whether to send a request command. In addition, when the main control device 200 receives an authentication request from the common entrance terminal 300, the main control apparatus 200 authenticates whether or not the stored household number and the household individual password match each other, and if the same, matches the common entrance terminal 300. The function of making the door open control can be performed by transmitting the authentication completion command.

The common entrance terminal 300 calls the generation terminal 100 or has a guard room call or a call function. In addition, the common entrance terminal 300, the door can be opened by a password or authentication card (RF card, etc.) in conjunction with other automatic doorway, receiving the door open signal from the household terminal 100 or guard terminal 400 automatic door You can also open.

The common entrance terminal 300 transmits a call, a call, and a visitor image to the generation terminal 100 to the generation terminal 100, and has a guard room call and a call function. And, the common entrance terminal 300, in conjunction with other automatic doorway can control the door opening by a password or RF card. At this time, it will be apparent that the authentication card is not limited to the RF card. In addition, the common entrance terminal 300 may receive the door open signal from the household terminal 100, the guard terminal 400 to open the automatic door, is installed between the main control device 200 and the guard terminal 400 It may also manage the same number, common password, and RF card number.

When the common entrance terminal 300 receives the call information from the guard terminal 400, the common entrance terminal 300 compares whether the call number of the call generation is the registered number and bypasses the call request command to the main control apparatus 200 ( Bypass) can be determined whether or not. In addition, when performing the door opening function, the common entrance terminal 300 may perform door opening control by authenticating the input password when using a common password instead of an individual household password. At this time, when the door opening request by the RF card, the door can be opened by comparing and authenticating with the RF card number stored in its own memory.

The guard terminal 400 calls the household terminal 100 or makes a call with the household terminal 100, and receives a call from the common entrance terminal 300, a call between the guard terminal 400, and the household terminal 100. Receives alarm data such as fire, gas and crime prevention, and outputs the corresponding alarm sound. In addition, the guard terminal 100 is connected to the common entrance terminal 300, it is possible to call only to manage the consent copper number to manage and manage when calling the household. At this time, it will be apparent that other movements are not excluded.
