The present invention relates to a communication relay control method, and more particularly to a communication relay control method of a group housing control device using a single coaxial line.

In the conventional group house, the main office interphone was installed in the management office and the interphone was installed in each household for the call between the management office and the household or the household. Therefore, a complicated telephone line is required between the household and the management office, and the line construction is complicated and expensive for construction and maintenance. In multi-family houses (apartments, apartments, etc.), many communication lines are required to perform functions such as calling from the guard room to each household and delivering announcements through voice broadcasting from the guard room.

1 is a schematic view for explaining an example of a conventional group house control apparatus. At this time, all households need at least two lines of wiring with the guard room management apparatus 10, respectively. In other words, two lines are required for the call, and one line must be added for broadcasting such as announcement of the announcement in the management office. In addition, it is not possible to simultaneously call or talk between generations, but only if the manager resides in the guard room, this function could be performed manually through the call relay. In particular, in the case of terraced apartments (houses with entrances in two houses), if there is a manager at each entrance, the burden of labor costs is great. In addition, the information control system for a conventional group house was only responsible for transmitting only pure information (control of elevators, emergency situations, power control, etc.). That is, the conventional general group house management system firstly requires wiring more than two wires between all households and the guard room, so the wiring is not easy and the construction cost is high. Second, the maintenance is not easy due to the many wirings and therefore the maintenance cost is high. Holding Third, when making a call, it is impossible to make calls between multiple generations, calls between each call or management office, and to realize this, a lot of additional costs must be paid. Fourth, the manager must always be on hand for call relaying, especially when there are a large number of entrances (stairs, etc.), which leads to an increase in labor costs. Fifth, as well as pure information (elevator control, emergency situation, power control, etc.), there was a problem in that it is difficult to transmit a variety of information in accordance with social development.

In order to solve the above problems, the group housing control apparatus using a single coaxial line invented by the present applicant will be described with reference to FIGS. 2 and 3 as follows.

The group housing control device of FIG. 2 is a single coaxial line (20, 45), household interphones (S) installed in each household connected to the single coaxial line 20 and the household or the manager at the entrance of each agreement The common entrance intercoms (S) installed in the common entrance used by a plurality of households, the copper controllers (30A, 30B) for controlling intergenerational calls in the neighborhood, the manager who manages one or more Sub-interphones 40A and 40B installed in the guard post, the central controller 50 for controlling and relaying calls in and out of the country, the frequency converter 55 and the computer 60, and the 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. 3 shows frequency allocation. To secure the communication channel, 256 communication channels are secured when the transmission frequency band is 30-35.12MHZ, the reception frequency band is 112.705-117.825MHZ and the bandwidth is 20KHZ. 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. Therefore, 127 currency paths can be formed. At this time, the central controller 50 polls each of the copper controllers 30A and 30B and the sub-interphones 40A and 40B in order to manage 254 communication channels according to the aforementioned frequency allocation. That is, the information about the copper is provided to the corresponding controller using the transmission / reception control channel, and the computer 60 or the setting device 50A is used to set such 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 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 transmission and reception control channels for transmission and reception of control data. The controllers 30A and 30B use CSMA / CD in the common entrance interphones 5 and generation interphones S and the base band AMI waveform to manage the call channels allocated from the central controller 50. Control communication is performed using the Carrier Sense Multiple Access with Collision Detection method. When there is an intra-call request from the controllers 30A and 30B, the intra-call call is performed using the call channels initially allocated from the central controller 50. In this case, the central controller 50 allocates an unused call channel among the unassigned call channels to the corresponding call controller, and the call controller reassigns it to the corresponding interphones. The calling 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 into the 117MHZ reception frequency band and outputs the converted frequency band. Generation interphones (S) detects various types of information (such as crime prevention, gas leakage, electrical leakage, etc.) of each generation through a sensor and converts it to the corresponding control data, and transmits the same to the corresponding controller through the control channel, and again 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 and 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, It is possible to comprehensively manage various types of information of each household in the city to be managed and take measures according to the respective 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, crime prevention, etc.) are needed, the safety information of households can be provided by selectively outputting the pre-stored voice signal through the public telephone network according to the information content of households. .

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

First, referring to FIG. 2, the collective housing control device invented by the present applicant is as follows.

4 to 6 show a flowchart for explaining a preferred embodiment of a communication relay control method of a group house control apparatus according to the present invention.

First, the communication relay control method of the central controller of FIG. 2 will be described with reference to FIGS. 2 and 4 to 6 as follows.

When the power is turned on, the central controller 50 determines whether communication information for communication relay is set (71). At this time, the communication information includes at least the household number of each household, the floor number, the household information on the lake, the household number using the common entrance, the household and common entrance number managed by each dynamic controller, and the community number managed by each post. . If such communication information is not set, polling communication cannot be performed, so setting device 50A is requested to set the communication information and receives setting data (73). Subsequently, when the polling communication is performed, the central controller 50 analyzes the setting data for the communication information so that the respective communication controllers 30A and 30B classify and transmit the necessary communication information (75). Subsequently, the central controller 50 performs polling communication (77). In order to look at this polling communication in more detail with reference to Figure 5 as follows. The central controller 50 transmits a polling address when performing polling communication (81). In this case, the polling address refers to a transmission address corresponding to the controllers 30A and 30B and the sub-interphones 40A and 40B, respectively, and the central controller 50 transmits the polling addresses in a preset order. Subsequently, it is determined whether there is a setting request for communication information from the controllers 30A and 30B and the sub-interphones 40A and 40B (81), and if there is a setting request, the setting data for the communication information is transmitted (82). ). Subsequently, it is determined whether there is a communication relay request from one of the polling responding device (the control controllers 30A and 30B and the sub-interphones 40A and 40B corresponding to the transmitted polling address), and 84 there is a communication relay request. For example, when the visitor wants to talk to household No. 205 in the 11th hallway, the central controller 50 polls this fact at the same place. When requested, the communication data is transmitted to the central controller 50, and the central controller 50 performs a communication relay so as to make a call with the corresponding hallway intercom with generation 205. At this time, if a communication error occurs (86) Perform communication maintenance and repair (87) If there is no communication relay request, it is determined whether a "no transmission data" message is received from the polling responding device (88), and if a message is received, the next polling communication is performed. This is to reduce the waiting time for receiving data, but when the polling address is not received and the message “no transmission data” is not received, that is, no response, If it is determined that the number of non-responses is large (89), error processing is performed on the polling responding device (90), that is, the setting device 50A is notified of the non-response of the polling responding device so that a communication error can be checked. By processing the error without waiting for the response of the non-responsive polling answering device, communication congestion caused by the polling responding device having a communication error can be prevented. When a signal NAK indicating that a communication error has occurred is received (91), the communication data is retransmitted (98). When informing signal (ACK) is received (95) transmits a communication end when maintenance or repair procedure. In this case, more than a certain number of failed communication relay (97), "no relative response" message (99).

Referring to FIGS. 7 to 8, a communication relay control method of the copper controllers 30A and 30B of FIG. 2 according to the present invention will be described.

2 and 7, the controllers 30A and 30B determine whether communication information for communication relay is set (101). If not, the controllers request setting and receive setting data to receive the communication information. The setting is made (103). At this time, the communication information includes at least the household number and common entrance number managed by the same controller and information about each household. Hereinafter, the transmission data (P) refers to the external transmission data to be sent from the same controller to the central controller, and the transmission data (A) refers to the data to be transmitted to the household or common hall managed by the same controller as the internal transmission data. P) refers to the data received from the central controller to the corresponding controller, and the received data (A) refers to the data received from the household or common hall managed by the corresponding controller. Subsequently, when there is a polling request from the central controller 50, if there is a transmission data P (107), the transmission data P is transmitted (111). Otherwise, the message "No transmission data" is transmitted (109). Subsequently, it is determined whether there is transmission data A (113), and if there is transmission data A, it is transmitted (115). Subsequently, it is determined whether there is a reception data P (117). If there is a reception data P, it is stored as the transmission data A, and if not, it is determined whether there is a reception data A (121). If there is a reception data (A), it is determined whether it is data to be transmitted in or out of the room (123). If the data is to be transmitted in the town, the received data (A) is stored as the transmission data (A) (127). (A) is stored as transmission data P (125). Next, communication maintenance and repair are performed (129). In this case, the aforementioned storage means includes a process of classifying data according to a place to transmit the data, including physically storing the data in a storage body. At this time, the above-described communication maintenance and repair process generates a signal (NAK) for notifying a communication error occurrence or a signal (ACK) for notifying normal reception of communication data in order to notify a communication state (131) and a generation intercom managed by the same controller. Alternatively, if a change occurs in hardware including the common entrance intercom, the controller detects the change and notifies the central controller 50 of the change (131). Subsequently, a process according to signals (ACK / NAK) indicating the communication status of the data transmitted from the same controller to the central controller 50 is performed (135). If the data relay fails, the message “No response” is sent to the corresponding apparatus. Send (137).

FIG. 9 is a flowchart illustrating a communication method of the sub interphones 40A and 40B of FIG. 2 according to the present invention. Referring to FIG.

First, the sub-interphones determine whether communication information for communication is set (140), and if not, request setting and receive setting data (142). At this time, the communication information includes at least the same number managed by the corresponding post, information on the common entrance in the town, and household information. Subsequently, it is determined whether there is a polling request from the central controller 50 (144), and if there is a polling request, it is determined whether there is data to be transmitted (146). If there is data to be transmitted, the data is transmitted (150), otherwise, the message "no transmission data" is transmitted (148). Next, it is determined whether there is reception data from the central controller 50 (152). If there is received data, it is determined whether it is screen data (154), and if it is screen data, the screen is displayed (158). Otherwise, processing for received data is performed (156). If there is no received data, it is determined whether a key is input (160), and if there is a key input, processing according to the corresponding key input is performed (162). Subsequently, communication maintenance and reception processing is performed (164).

As described above, the communication relay control method of the group house control apparatus according to the present invention enables a quick connection during polling communication by reducing the communication waiting time, and the data generated in the household is managed exclusively by the same controller, and the sub-interphone However, data generated from the controller can be managed exclusively by the central controller, so that data can be relayed without failure of some equipment without affecting the overall system operation.
