The apparatus includes a main control system, a plurality of communication lines connected to a system bus, a plurality of data lines connected to a system bus, a plurality of power supply units, and a plurality of diagnosis units.

Description

Self-diagnosis method and device for data line and call line of multi-unit house management system

1 is a view for explaining a bus control method of a conventional multi-family house management system.

2 is a block diagram according to an embodiment of the present invention.

3 is a configuration diagram connecting the generations 101 to 103, the management room main device 105, and the self-diagnosis unit 201.

4 is a flow chart according to an embodiment of the present invention.

The present invention relates to a system using a bus control method of a multi-family house management system, and more particularly, to a self-diagnosis method and apparatus for a data line and a telephone line.

The bus control of the conventional multi-family house management system, as shown in FIG. 1, is a transmission / reception line unit (DATA) for data transmission and a communication line unit for voice transmission between generations 1-k (101-103) and the management unit main unit 105. (CH1-CHN) are connected to share. For example, each bus line is shared between the transmission / reception line section DATA and the call line sections CH1 to CHN in each household 101 to 103, and each of them is a transmission / reception line section DATA in the management room main unit 105. ), Which is connected to the call line unit CH1 to CHN, each of which is not individually configured, and the transmit / receive line unit DATA is as the transmit / receive line unit DATA, and the call line unit CH1 to CHN is the call line unit. It is comprised so that each may share as (CH1-CHN).

Such a configuration can affect the entire system if a line is opened, shorted, or miswired in one generation, or if a product fails. The reason for this is that there is no self-diagnostic function in the transmission / reception line unit DATA and the call line unit CH1 to CHN of the management unit main device 105. Therefore, it is difficult to immediately recognize such a phenomenon and difficult to identify the cause of the defect. There was this.

Therefore, the object of the present invention is to add the self-diagnostic function of the transmission and reception line unit (DATA) and the call line unit to the management unit main device to regularly diagnose the line state and immediately notify the management room of the abnormal problem, and to take action on the line state if necessary. The present invention provides a method and apparatus for displaying or printing a screen to easily deal with a problem.

In order to accomplish the above object, the present invention connects a power supply unit and a line diagnosis unit to a connection line of a transceiver unit and a communication line unit that are shared with each generation and the management unit main device, and the power supply unit supplies power to each line, and diagnoses a line. The unit is characterized in that it is configured to detect the power (signal) of the line to diagnose the line state.

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

FIG. 2 is a circuit diagram according to the present invention, and a specific example of the self-diagnostic portion 201 of FIG. 2 is shown in detail in FIG. The transmission / reception line unit DATA of the management room main unit 105 connects the transmission / reception unit DATA included in the self-diagnosis unit 201 of the management room main unit 105 through the call line 221, and the call line unit CH1. The first to N power supply units 320, 304, and 307 included in the self-diagnostic unit 20 are connected to the connection lines 222 to 224 of ˜CHN, and the first to N line diagnosing units 303, 305, and 308 are the generation 101. It is connected to the call line part of CH1 ~ CHN.

4 is a flow chart according to an embodiment of the present invention, the first step of supplying power to the power supply in the state that the channel of each generation is disconnected, and diagnosing the short state of the communication line in the line diagnostic section, and the first step of In the second step of transmitting data to the household in the state that the power supply is supplied with power, connecting from the first channel to the Nth channel in turn, and in the second step, misconnection such as opening of a communication line, short circuit, etc. from the self-diagnosis. A third step of diagnosing and a fourth step of printing or displaying the state of each line by the diagnosis of the third step.

Therefore, when a specific embodiment of the present invention is described in detail with reference to FIGS. 2 to 4, the management room main unit self-diagnosis unit 105 is constructed in the process (4a) in the state configured as shown in FIG. 2 and FIG. Enters self-test function execution mode with all channels disconnected. Then, in step 4b, the first power supply unit 302 is controlled to supply power, and in step 4c, the first line diagnosis unit 303 to the Nth line diagnosis unit 308 diagnose the line state in turn. In step 4d, it is checked whether power is supplied to the Nth power supply unit 307.

If power is not supplied to the Nth power supply unit 307 in step (4d), power is supplied only from the next power supply unit in step (4f), and steps (4c) to (4d) are repeated. However, if power is supplied to the Nth power supply unit 307 in step (4d), the generation 1 is designated in step (4e), and data is transmitted and received by the self-diagnosis unit 201 in step 4g. Check if the communication status is normal. When it is normal in step (4h), only the first power supply unit 302 supplies power, and in step 4j, data is transmitted to the household to connect only the call line unit CH1. In step 4k, the first line diagnosis unit 303 to the Nth line diagnosis unit 308 sequentially diagnose the line state until the call line unit CHN is connected. If the call line unit (CHN) is not connected in step (41), the data is transmitted to the household in step (4r) to connect only the next call line unit (CH), and then repeat steps (4k) to (4l). . However, if it is connected to the telephone line CHN in the process (41), when the power is not supplied from the Nth power supply unit 307 in the process (4m), the power is supplied only to the next power supply unit in the process (4n) (4j). Repeat the process from) to (4m). However, when the power is supplied from the Nth power supply unit 307 in step 4n, if the generation K is not diagnosed in step 4p, the next generation may be designated in step 4o to 4p. Repeat the process. However, if the diagnosis is made up to generation K in step (4p), the self-diagnosis is displayed and printed in step (4g).

As mentioned above, the self-diagnosis function of the data and call lines is added to the management room main device to regularly diagnose the line condition and immediately notify the management room when a problem occurs, enabling action, and displaying or printing the line status on the screen if necessary. There is an advantage that it is easy to see the problem.
