The present invention allows multi-generational households to live in groups and remotely monitor each generation (eg, theft, fire, and gas leaks) through a host computer installed in a predetermined place (eg, the central management office) in a house, and at the same time, remote meter reading The present invention relates to a group house management method and apparatus using a data over voice (DOV) signaling method that facilitates data communication.

Conventional group housing management apparatus employs a DTMF frequency shifted through the main distribution board or a data communication method using an audible modem followed by a startup sound after scanning using inaudible tones.

The group management system as a remote information system widely used in the related art manages a database by managing various data services of subscribers as shown in FIG. 1, and at the same time, a line integrated control device via a modem communication line 102. A host computer 100 which communicates with 103 and directly scans the meter reading and subscriber status and transmits the result to the utility center 101; Based on the meter reading result received from the host computer 100 and the scanning result of the subscriber status, a computerized operation such as receipt issuance and a place for directly performing an action according to the status of each subscriber (eg KEPCO, Gas Corporation, Water Works) And a utility center 101 as a computer of a fire station; A modem communication line (102) for communication between the host computer (100) and the line integrated control device (103); An indoor facility 108 having a meter 110, various sensors 111, and the like, connected to a meter 110 to be read by analyzing a metering operation command received from the host computer 100; The subscriber line 107 which is in parallel connection state is connected to the main distribution board 105 which is the first output terminal for connecting the subscriber line 107 from the local and private exchanges 106 to the subscriber line 107. After connecting and controlling the multiplexer 104 to be connected without dialing, receiving and reading the meter result through the communication with the premises facility 108 and transmitting to the host computer 100, and whether there is an abnormality of each subscriber by a periodic scanning method. And a line integrated control device 103 for monitoring the occurrence of an emergency state and transmitting it to the host computer 100; A national and private switchboard 100 for realizing various services through a telephone line; The parallel connection between the subscriber telephone and the subscriber line 107 receives a metering command from the line integrated control device 103, and the line integrated control device 103 receives the meter reading value of the meter in a normal state in which an emergency state or an abnormal state does not occur. And a terminal 112 for detecting and transmitting an emergency alert state through various sensors 111 and transmitting and receiving respective data.

The line integrated control circuit device 103 in the group house management system having such a configuration is configured to provide the home facilities 108 through various sensors 111 at idle time when the metering operation command is not received from the host computer 100. The status of abnormality and emergency alarm is monitored, and the multiplexer connected to the main distribution board 105, which is the first output terminal of the national and private switch 106, for connecting to the subscriber line of each household to connect the subscriber line 107. After controlling the 104, the subscriber line is connected without dialing, and then the DTMF frequency shifted to the indoor equipment is transmitted or the tone tone of the inaudible frequency is received.

In the shifted DTMF frequency communication method as described above, if the shifted DTMF frequency is received from the in-line facility 108 from the line integrated control device 103, it is determined to be in a normal state. The DTMF frequency is transmitted to the line integrated control device by transmitting another DTMF frequency shifted if it is found to be abnormal, to the host computer 100 in the line integrated control device 103 and to the host computer 100 for the utility. The transmission is sent to the center 101.

In the case of the meter reading operation, the DTMF frequency shifted from the line integrated control device 103, which receives the meter reading command output from the host computer 100 via the modem communication line 102, to the indoor equipment 108, is transmitted. Then, when receiving the normal DTMF frequency shifted from the indoor facility, the shifted DTMF frequency is interrupted, the remote meter command is transmitted to the indoor facility 108, and the reading result is received from the indoor facility 108. 100).

In addition, in the case of scanning the indoor equipment 108 using the tone sound of the inaudible frequency, after connecting the subscriber line by controlling the multiplexer 104 connected to the main distribution panel 105, If there is a reception, it is determined to be in a normal state. If there is no reception, it is judged to be an abnormal state, and a start-up sound for starting up the indoor equipment is transmitted, and then a modem of an audible frequency is set up to transmit and receive information.

In this way, the conventional remote information system using the DTMF frequency has audible frequencies, which interferes with subscribers' calls, and cannot transmit or receive various information during the call. In case of facility scanning, it takes a lot of time for data communication due to the setup of audible modem following the facility and the start-up sound in case of an abnormality, and it also causes a problem for the subscriber's call, and it has a disadvantage of failing to transmit an emergency situation during the call. .

In addition, the multiplexer connected to the main distribution panel requires a large installation cost to attach to the distribution panel of the private switching network of a small group house rather than a large apparatus such as a trunk line switchboard, and a line integrated control device for controlling the same is also designed. There was a problem such as to become very complicated.

An object of the present invention is to be able to perform various data communication in a short time, as well as to easily connect to the private switching network distribution panel of small group houses or the interphone distribution panel of the management room to perform various data services such as alarms and meter readings. The present invention provides a method and apparatus for managing a group house using a non-audible band modem (DOV) signaling method.

It is another object of the present invention to perform data communication using an inaudible frequency of 32KHz, which allows the subscriber to easily understand the abnormal state in each household, etc. The present invention provides a group housing management method using a signaling method and an apparatus thereof.

Referring to the effects of the present invention as follows.

First, the line integrated control device 202 detects the abnormality of the indoor equipment 207 and the emergency alert condition. The line integrated control device 202 is connected to the subscriber line 206 of each household to connect the subscriber line 206. Connected to the main facility 207 through the cable 203 connected in parallel to the main switchboard 204 of the switchboard and the intercom device 205 without a separate control, and then a subaudible band modem (DOV) signal to the indoor facility 207. The state request data of the scheme is transmitted through the DOV transceiver 212.

In this case, the inaudible band modem (DOV) transceivers 212 and 217 installed in the line integrated control device 202 and the indoor facility 208 use a 32KHz carrier frequency of amplitude shift keying (ASK) modulation. When the voice communication is performed between predetermined subscribers, the DOV transceivers 212 and 217 detect only a 32 kHz DOV signal, so that transmission and reception of predetermined data is possible regardless of communication between subscribers.

Therefore, when the DOV transceiver 217 connected to the indoor equipment 207 receives the DOV signal status check request data from the DOV transceiver 212 of the line integrated controller 202, the data is stored. When it is in steady state, it sends the steady state response data of DOV signaling again.

That is, in the indoor facility 207, in case of an emergency alert such as an abnormal state or an abnormal state detection of the sensor 209 such as a fire, theft, crime prevention, gas sensor, etc., predetermined data indicating each state is lined up by DOV signal method. The integrated line controller 202 transmits this data to the host computer 200 and transmits the data back to the host computer 200 so that the operator can quickly know the state of the predetermined household.

In addition, when an operator requests a meter reading service through the host computer 200, the DOV transceiver 212 of the line integrated control device 202 receives a meter reading command from the host computer 200 and then performs the same. By connecting the subscriber line 206 to the DOV transceiver 217 installed in the domestic facility 207 and transmitting the meter reading command using the inaudible band modem (DOV) signaling method and receiving the results. The remote meter can be processed quickly.

In order to explain this more clearly, the following description will be made with reference to FIGS. 3 to 8.

3 is a flow chart showing a main program executed by the host computer 200, and includes a function of managing each board abnormality, subscriber information management, and remote meter reading of the system, and a line with the host computer 200. Although not shown, the integrated control device 202 is provided with an RS-232C interface to facilitate data communication.

When the initial power is input, the host computer 200 initializes the system first (SO), and then detects whether a desired job is selected from the operator (S1).

When a predetermined job is selected by the operator, the subscriber management, system management, and remote meter reading subroutines corresponding to the respective selection keys are performed.

However, if the system is normally operated even when there is no work selection, various data on each board and alarm situation are continuously input from the line integrated control device 202 (S2).

When the predetermined data is input as described above, it is detected whether the data is normal data (S4), and in the next step (S5), data on the state of the main unit and the line integrated control device 202 are judged, and as a result, the normal state. If so, go to S6.

In the step S6, if there is no data input from the line integrated control device 202, the contents are output through a screen and a printer. In step S5, the state data of the main device and the line integrated control device 202 are stored. Otherwise, the input data is separated by type.

In step S8, it is determined whether or not the various alarms and the line integrated control device 202 are abnormal among various data. In this case, if the corresponding alarm data is data from the indoor equipment 207 in step S9, the alarm is searched through the database. The type, name, address and time of occurrence are output and the process returns to the second step S2 to receive data continuously.

If the subscription management key is operated by the operator during this process, the host computer 200 performs the subscriber management subroutine as shown in FIG.

That is, when the subscriber management key is operated by the operator (DO), it waits for a predetermined command to be input (D1), and when the predetermined key is operated, the command is inputted data (D2), data inquiry (D3), and data deletion (D4). ) Detect which command is the one of command) and data modification (D5) sequentially, and if any command is inputted, it is determined whether the data is correct data (D6). If it is not normal data, it outputs an error signal to the operator. Will complete its task and wait for the next command.

However, when an operator operates a predetermined key for remote meter reading, the host computer 200 executes the remote meter reading subroutine shown in FIG. 5. If a predetermined command is input by the operator while waiting for a command of the command, the command sequentially checks whether the command is a periodic meter reading (T2), an instant meter reading (T3), a meter reading initialization (T4), or a meter reading print (T5) command. If a predetermined command signal is detected and inputted, it is determined whether there is a subscriber corresponding to the data input in step T6.

As a result of the above determination, if there is no subscriber, an error signal is output, and if there is a subscriber, it is checked whether the result value for the command is received in step T8, and if it is not within a predetermined time, it is timed out (T9). It will complete the task and wait for the next command.

At this time, if the meter reading is performed immediately in the T3 process, the command can be always given by the operator if the subscriber wants to know the metering port value of the subscriber, and if the result value for the given command is not sent, the timeout process is performed in the T9 process. It was made.

In addition, in the case of regular meter reading, if the operator inputs the desired date and time, the subscriber can receive the information on the subscriber at a predetermined time and periodically read the meter reading. 207) initializes the value currently displayed on the meter reading meter.

6 shows the system management subroutine. When the system management key is operated by the operator (MO), the host computer 200 waits for the next command (M1).

When the operator selects any one of the mounting information inquiry (M2), the coupling device control (M3), the mounting information load (M4), and the alarm inquiry command (M5), and the predetermined data is input, the data input in the M6 process is normal. If it is not normal, an error signal is outputted. If normal data, M8 detects whether a result value for the data is sent.

As a result, if the result value is not sent even though a certain time has elapsed, timeout processing is performed (M9). If the result value is transmitted before the predetermined time has elapsed, the result value is separated by type (M10). It will complete the task and wait for the next command.

On the other hand, Figure 7 shows a relay program of the line integrated control device 202, the line integrated control device 202 is a host communication unit (HCU), channel control unit (CCU), coupler subscriber unit ( CSU) and alarm unit (ALU) are provided inside.

At this time, the HUC is an upper-end unit of the line integrated control device 20, and performs a steady state check (A1) with the host computer 200 at regular intervals, thus notifying whether there is an abnormal state and receiving registration information of the CCU. By monitoring the registered CCU (A3), the alarm information of the CCU and CSU is collected and transmitted to the host computer 200 together with the HCU's own alarm information (A11).

In addition, the CCU is a unit connected between the upper HCU and the lower CSU, and performs a steady state check (A8) with the HCU at regular intervals, and receives the registration information of the CSU (A11) to monitor the corresponding CSU.

That is, the command received from the HCU is analyzed and sent to the corresponding CSU (A17) and the result is sent to the HCU.

In addition, the CSU performs DOV modem communication through the DOV transceiver 217 of the indoor equipment 207 installed in each household, collects various alarms and meter data installed in the home (A25), and delivers the data to the upper CCU (A26). At the same time, a function of transmitting (A25) various control commands of the host computer 200 to the indoor equipment 207 is performed at the same time.

In addition, the CSU periodically checks whether there is an abnormality of the indoor equipment 207 and the state of the track to notify the upper stage immediately when an abnormal condition occurs, thereby allowing the operator to take prompt action.

On the other hand, the ALU obtains the fault information of the line integrated control device 202 and generates it as a light and a sound signal so that the administrator can know the fault state of the line integrated control device through visual and auditory, and the line integrated control device ( It has a function to inquire the status of all units of the unit 202 and the indoor facility (207).

In addition, the ALU sends and receives a steady state confirmation signal (A2) periodically with the HCU, and processes and receives failure and recovery messages (A8 and A15) of the lower stages of the CCU and the CSU, and the normal presence of the HCU responds to the normal signal. It is judged by (A2).

8 shows an operation program of the indoor equipment 207. After initializing all data of the indoor equipment 207 in the process C1, the line integrated control device 202 of the indoor equipment 207 in the process C2. The DOV transceiver 212 receives information about various sensors 209 and meters installed in the indoor facility 207 in a subaudible band modem (DOV) manner (C2).

Subsequently, in the case of receiving the status check request data from the line integrated control device 202 in the process C3, the line integrated control device 202 receives the steady state response data of the DOV signaling method in the process C4 when the state is normal. In the C5 process, the process returns to the process C2 after checking whether there are any abnormalities in the various metering ports installed in the home facility 207 and whether the sensors are abnormal.

However, when an emergency alarm signal such as detection of an abnormal condition is detected in various sensors 209 such as fire, heat detection, method, gas and emergency sensor, the corresponding alarm occurrence state is displayed and the buzzer is driven as in the process C6. (C7).

Thereafter, when the DOV transceiver 217 of the indoor facility 207 transmits data indicating respective states to the line integrated control device 202 using the DOV signal method (C8), the DOV of the line integrated control device 202 is transmitted. The transceiver 212 transmits the reception completion confirmation data indicating that the alarm data has been received to the indoor equipment 207 in the DOV signal method.

At this time, the indoor equipment 207 determines whether the data transmitted from the line integrated control device 202 is the reception completion confirmation data (C9), if incorrect, it is repeatedly transmitted three times, and reception completion confirmation If the data is correctly received, the test returns to the process C3 after checking the abnormality of various sensors and the abnormality of the metering port (C10).

In the process C11, when the indoor facility 207 receives a service request such as a meter reading request and boundary setting from the line integrated control device 202 as a DOV signal method, the indoor facility 207 analyzes the requested service. In step C2, the service result data is transmitted to the line integrated control device 202 in a DOV signaling method.

Since the line integrated control device 202 transmits the reception completion confirmation data indicating that the service result data has been received to the indoor facility 207 in the DOV signal method, the line integrated control device 202 receives the reception completion confirmation data to determine whether the reception completion confirmation data is received in the indoor facility 207. If it is incorrect (C13), the service result data is repeatedly transmitted three times.

If the normal reception completion confirmation data in the above, by performing the C10 process as described above to check the presence of various sensors and the abnormality of the metering port is returned to the process C3.

In addition, the remote meter is to adopt the interrupt method as in step C14 to check the meter port periodically every 10mS to check the pulse detection and abnormality of the various meters installed in the premises equipment 207 to change the meter reading value When the metering service request signal is transmitted from the line integrated control device 202, the values are transmitted to the line integrated control device 202 by the DOV signal method so that the host computer 200 can know it. .

As described above, according to the present invention, various data communication can be performed in a short time by transmitting and receiving data required for group house management by a non-audible band modem (DOV) signal system. It can be easily connected to private switching network distribution panel or intercom distribution panel of management office to perform various data service such as alarm and meter reading, and data communication using 32KHz inaudible frequency. You can easily grasp the abnormal status in each household without interrupting the call.
