Description

Group control device and routing method of data packet in the device

1 and 2 are views for explaining a group house control device invented by the present applicant.

Figure 3 is a detailed block diagram of the controller in the collective control unit according to the present invention.

The present invention relates to a group house control apparatus and a routing method of data packets in the apparatus, and more particularly, to a group house control apparatus capable of easily coping with a communication environment change and a routing method of the data packet in the apparatus.

FIG. 1 is a block diagram illustrating a group house control device invented by the present applicant.

The group house control apparatus of FIG. 1 has a single coaxial line (20, 45), household interphones (S) installed in each household connected to the single coaxial line (20) and the household or manager at the entrance of each building The main entrance interphones (5) installed in the common entrance used by a number of households, the copper controllers (30A, 30B) for controlling inter-generational calls in the neighborhood, the manager who manages one or more Sub-interphones 40A and 40B installed in a post place, a central controller 50 for controlling and relaying calls in or out of the country, a frequency converter 55 and a computer 60, and a setting device 50A. . The common entrance interphones 5 installed in the common entrance and the generation interphones S installed in each of a plurality of households using the common entrance are connected to one through a single coaxial line 20. In addition, the copper controllers 30A and 30B, the sub-interphones 40A and 40B, and the central controller 50 are commonly connected through a single coaxial line 45. At this time, multi-frequency division communication is performed for a call and information exchange using a single coaxial line. For this communication, a communication channel is secured through frequency allocation. The present invention divides a given frequency band into a transmission and reception frequency band, and at this time, divides each band to have a predetermined bandwidth (BAND WIDTH) and uses a method of allocating each bandwidth to one communication channel. 2 shows a frequency allocation diagram. In order to secure the communication channels, 256 communication channels are secured when the transmission frequency band is 30-35.12 MHz, the receiving frequency band 112.705-117.825 MHz and the bandwidth is 20 MHz. Therefore, the number of communication channels can be changed according to the determination of the frequency band and the bandwidth. Thus secured 256 communication channels are secured two control channels for transmitting and receiving control data between each device, and 127 communication channels for transmission and reception. Thus, 127 currency paths can be formed. The central controller 50 polls the copper controllers 30A and 30B and the sub-interphones 40A and 40B in order to manage 254 communication channels according to the frequency assignment described above. That is, the information about the copper is provided to the corresponding controller using the transmission and reception control channel, and the setting device 50A is used to set the information. In addition, the central controller 50 allocates a call channel necessary for inter-generational call relaying by the same controllers 30A and 30B. That is, a predetermined number of communication channels among the secured 254 communication channels are allocated to the copper controllers 30A and 30B. In addition, if there is an additional call channel allocation request from the controller, an unused communication channel among the communication channels not allocated to the controller is additionally allocated. At this time, the central controller 50 and the controllers 30A and 30B use a transmission and reception control channel for transmitting and receiving control data. The controllers 30A and 30B are CSMA / CD in the common entrance interphones 5 and generation interphones S and BASE BAND AMI waveforms in order to manage the call channels allocated from the central controller 50. Control communication is carried out by the Carrier Sense Multiple Access with Collision Detection method. When there is an intra-call request from the same controllers 30A and 30B, the intra-call relaying is performed using the call channels initially allocated from the central controller 50, and when the off-call request is received, the external call is sent to the central controller 50. In this case, the central controller 50 allocates an unused call channel among the unassigned call channels to the corresponding controller, and the controller reassigns it to the corresponding interphones. Accordingly, the call calling and called interphones can be allocated two call channels for transmission and reception. The frequency converter 55 is connected to the single coaxial line 55 and converts the 30MHz transmission frequency band inputted to the 117MHz reception frequency band and outputs the same. Generation interphones (S) detects various information (method, gas leakage, electrical leakage, etc.) of each generation through a sensor and converts it into the corresponding control data and transmits it to the corresponding controller through the control channel and again to the central controller ( 50) to pass. At this time, the central controller 50 transmits to the guard intercom in the guard house that manages each household, and informs the manager who resides in the guard station. Accordingly, the guard interphones 40A, 40B can make a call with the household within their management or the consent household or other guard that they do not manage through the call relay of the central controller 50, and Various kinds of information of each household in this town to be managed can be comprehensively managed, and different measures can be taken for each piece of information. At this time, the computer 60 transmits and receives information data with the central controller 50, stores and manages the information for each generation, and performs information processing, and exchanges information through a communication network. In particular, when household safety measures (gas leak, fire, method, etc.) are needed, the safety information of the household can be provided by selectively outputting the pre-stored voice signal through the public telephone network according to the information of the household.

However, such a group house control device has one generation interphone installed in each generation of the group house, and the data is transmitted by the generation intercom by the household controller which polls the generation interphones one by one by the same controller that manages and relays communication data. Receive the data and perform data relay to another generation interphone to transmit it. Therefore, since the controller is limited by the number of generation interphones that can poll, a plurality of controllers are required to manage all generation interphones in the group house. When a plurality of dynamic controllers manage all households in a building, the routing of data packets in a building requires a complicated process of routing data in the same control period and transferring it back to the household intercom by polling. Central control for data transmission and reception during the same control period should manage and relay the data of a plurality of dynamic controllers. In addition, when there are a large number of households in a single-family house, multiple polling controllers must manage one household in order to poll all household interphones. In this case, a complex structure is required to find a communication path of data for inter-generational communication. Have.

Accordingly, an object of the present invention is to reduce the burden of polling all generation interphones managed by the existing control unit by communicating between the control unit and the generation interphone in a CSMA (Carrier Sensed Multiple Access) method to solve the above problems. In addition, the present invention provides a group house control device and a data routing method in the device, which are not limited by the number of generation interphones managed by the same controller due to polling communication.

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

3 is a block diagram showing the configuration of the controller in the collective control unit according to the present invention.

The controller shown in FIG. 3 has a controller 72, a CSMA interface 74, a plurality of CSMA controllers 75A, 75B, and 75C, RAM 72 for storing data, and data loss when the power is turned off. It is composed of a backup battery (73) for preventing.

All generation interphones are connected to the corresponding CSMA controllers 75A, 75B, and 75C through a single coaxial line 20, and transmission data of all generation interphones are transmitted and received through each CSMA controller. The data received from the generation interphone to the CSMA controller is transmitted to the corresponding CSMA controller to which the receiving generation interphone is connected if it is in-house data by the same controller micom 71, and to the central controller via a single coaxial line 45 if it is out-of-data. The controller shown in FIG. 3 is installed in one building of a group house, and all communication lines to which household interphones are connected are connected. Communication with each generation interphone transmits and receives data through CSMA controller managing CSMA for each communication line. In addition, the controller requests the controller setting data to the central controller upon system initialization and receives a routing table for routing communication data packets in the neighborhood. The central controller transmits the configuration data for communication data routing of the controller when the system is initialized or when requested, and processes data (fire, method, etc.) of the generation interphone received through the controller, In addition to the relay function will be performed. The CSMA controllers 75A, 75B, 75C are responsible for CSMA communication with generation interphones connected on the communication path, thereby reducing the burden on the communication of the controller microcomputer 71. In addition, the CSMA controllers 75A, 75B, and 75C transmit the communication data received from the controller MICOM 71 through the CSMA interface 74 to the corresponding generation intercom, and transfer the data received from the generation intercom. The communication wiring structure connecting the controller and each generation interphone is connected to a CSMA communication line such as generation interphones (for example, 101, 201, 301, ...) of the same lake on each floor.

When there are many households in a building, each generation interphone is managed by a single copper controller by CSMA instead of using a plurality of copper controllers.

Looking at the operation according to the above configuration as follows.

When the system is initialized, the controller requests the controller to set up the communication of the controller. At this time, the central controller transmits a routing table including routing information for relaying each communication data to the corresponding controller in response to a setting request of the controller. At this time, the routing table is shown in the following table.

In Table 1, the setting code refers to a code indicating the setting of the controller, where N is the number of CSMA controllers installed in the controller, and lakes 1 to n are connected to each CSMA controller from CSMA controllers 1 to n. Means the maximum lake number of the generation intercom. Subsequently, the controller counts whether each CSMA controller is installed and the number of CSMA controllers through the CSMA interface at system initialization. If the number of CSMA controllers in the received routing table does not match the number of CSMA controllers actually counted, the controller does not relay the communication packet and notifies the central controller of the routing table error. When there is no error in the routing table received from the central controller, the received routing table is stored on the RAM 72. At this time, the backup battery 73 is an auxiliary power supply for the controller to protect data recorded on the RAM 72 due to power failure or the like. Therefore, data loss can be prevented due to an unexpected power failure through the backup battery 73. The routing table recorded on the RAM 72 is shown in the following table.

The setup code and the information on the number of CSMA controllers shown in Table 1 are excluded. In Table 2, lakes 1 to n have a value excluding the floor number from the lake of each generation interphone, that is, number 1 for 101 and number 7 for 107, and are connected to a communication line of each CSMA controller. It has only the value for the household interphone with the largest lake number among the intercoms. Since the above routing table is received from the central controller, the routing table can be reset through the central controller even if the communication environment such as the wiring structure or the increase or decrease of the CSMA controller is changed.

The central controller then sends a data packet to the corresponding controller. At this time, the data packet includes information on the communication ID of the corresponding household interphone as the destination. Therefore, the controller transmits the data packet to the generation interphone through the generation interphone communication ID. At this time, the communication ID of each household intercom becomes the floor and the lake of the household. That is, for example, in the case of 711, the communication IDs are 7, 11.

When a data packet is received, the controller retrieves the generation interphone communication ID in the data packet. The lake of the generation intercom communication ID of the received destination is searched, and the routing table value is compared with the value of the lake of the target generation in order from index 1 in the routing table. As described above, since the routing table is configured with the maximum number of lakes connected to each CSMA controller, starting from the minimum, the number of CSMA controllers installed in the same controller, the value TABLE [N] belonging to index n means that the number CSCS controller Manages generation interphones from TABLE [N-1] + 1 to TABLE [N]. Therefore, if the lake value of the target generation is equal to or smaller than the value of the routing table, the index becomes the number of the CSMA controller to which the same controller forwarded the packet. Therefore, the controller finds the CSMA controller to which the destination generation interphone is connected by comparing the routing table with the communication ID of the destination generation interphone of the data packet to be transmitted. The controller then sends the received data packet to the found CSMA controller. Then, the corresponding generation interphone receives the data packet through the CSMA controller. At this time, when the data packet is transmitted from the CSMA controller to the same controller, it is determined whether the data packet is an in- or out-of-east data packet. As described above, the data packet is transmitted to the generation interphone as the destination using the communication ID and the routing table of the generation intercom as the destination of the data packet.

As described above, in order to remove the limitation of the number of generation interphones managed by the existing copper controller, all generation interphones in the community are handled by a single copper controller through the CSMA controller, thereby eliminating the burden of polling all household interphones. In addition, there is an advantage that it can be easily reflected in setting only the routing information for the change of the wiring structure.
