JPH05160839A - Equipment connection state verification device - Google Patents

Abstract

PURPOSE:To allow the installation work personnel to simply check the connection state between buses and equipments by combining a map expressing addresses being identification numbers of IFUs (interface units) on the bus, the result of communication with a connected equipment and data resulting from recording the information. CONSTITUTION:An address information list means 13 displays a map and an address selection means 14 is used in selecting address on the map to be checked. Then the communication to each equipment is executed to all selected addresses via an IFU 2 by a communication means 15. Then detailed information of each address is displayed by an address information display means 16. In this case, the check result is expressed on the map by a simple symbol and the result is listed. Finally an address information storage means 17 is used in storing the result of check and then the result is compared as preceding data at a succeeding check.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device connection status verification device for verifying the address setting status of a plurality of devices connected to a bus.

[0002]

2. Description of the Related Art Conventionally, a device connected to a home bus,
The address information of various devices was only visually confirmed by the contractor at the time of construction. In this case, what is compared and referred to is the design document in which the connection address is designated in advance and the visual result of the contractor. Therefore, when a trouble such as a malfunction of the equipment occurs, the contractor checks the suspicious points one by one.

[0003]

However, in the above-mentioned configuration, it takes time to confirm the address setting status after connecting the device to the home bus, and the accuracy is insufficient. Moreover, it is up to the contractor to manage the address setting history. It seems that when trouble occurs, considerable effort and time are spent until the cause of the failure is specified. At the time of setting the address, it is preferable to inform the contractor of at least the information about the address that is already used and the presence or absence of the IFU abnormality.

In view of the above problems, it is an object of the present invention to provide an address verification device capable of listing address setting conditions and obtaining address information including past information by a simpler operation. ..

[0005]

In order to solve the above problems, the address verification apparatus of the present invention sends a telegram to each device to detect the connection status with each device, and detects a response thereto. Communication means, address information display means for displaying the address information, which is detailed information regarding the address usage status, assigned to the response, and address information storage capable of displaying the acquired address information as past data at a later date. Means and display means for comparing the past data with the current address information and displaying the matching result.

[0006]

The present invention operates as follows with the above configuration. Now, it is assumed that various devices to be controlled and the device connection status verification device are connected to the transmission path via an interface unit (hereinafter referred to as IFU). Here, when an address verification device is activated after selecting an arbitrary address, each IFU connected to the home bus and having an address is communicated one by one in order to verify whether or not the address is used. To go. When the communication is completed, the use / unuse of each address, the name of the device connected to the used address, the attribute of the used line (hereinafter referred to as attribute), and the comparison result with the address information acquired in the past are displayed. To be done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A device connection status verification apparatus according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram of a verification system using the device connection status verification device of the present invention. In the figure, 1 is a transmission line, 8 is a device connection status verification device, 2 is an interface unit that connects the transmission line 1 and the device connection status verification device 8 (hereinafter,
IFU), 9, 10 and 11 are telephones,
Home automation devices such as fire sensors and home bus controllers, IFU3, 4,
It is connected to the transmission line 1 via 5. 6 and 7 are unused IFUs to which nothing is connected. It is assumed that addresses are assigned to the IFUs so that they do not overlap.

FIG. 1 is a block diagram showing the configuration of a device connection status verification apparatus according to an embodiment of the present invention. CPU 12
It controls the operation of each of the following 13 to 17. The address information list means 13 is composed of a user interface, and displays a list of addresses on the home bus in a map form. The address selecting means 14
The user interface is the main means for selecting an address by moving the cursor using the address information list means 13 as if it were a map. The communication unit 15 communicates with the device connection status verification device via the IFU 2.
It is a means for transmitting and receiving a telegram data packet to and from the home bus, and FIG. 4 is a packet configuration diagram thereof. PR is a packet priority, SA is a source address, DA is a destination address, CC is a control code, BC is a data length, and FCC is a frame check code. Each is a start bit, a parity bit,
It has an 11-bit configuration including stop bits.
The address information display means 16 is means for processing and displaying the address information obtained by the communication means 15 into a form effective for the user. Address information storage means 17
Is means for accumulating newly acquired address information as data for past data.

The operation will be described below with reference to FIG. (1) Display the address map and list the usage status of all addresses. (2) Move the cursor to the address position to be verified on the address map. (3) With the cursor, select any individual address, all addresses included in a specific group, or all addresses. (4) If all addresses are selected, proceed to step (6), otherwise proceed to (5). (5) If you have selected any address, proceed to (6),
If another address is selected, the process returns to step (2). (6) Start communication. (7) The process of (8) is repeated as many times as the number of selected addresses. (8) From the verification device, send a message with the "attribute request" command to one selected address, and obtain address information from the result (for each response obtained by communication, display the resulting display value Figure 4 shows the procedure up to setting
Explained in). (9) Terminate communication. (10) The address information obtained in the above steps is the name of home automation equipment connected to the home bus, the attribute, the result of comparison with the data accumulated in the past,
Items are displayed in the form of. When selecting the address, the home automation devices 9, 10, 11 are selected.
If the address assigned to is selected, the detailed item is displayed as the used address. If an unused IFU 6, 7 address is selected, the address is considered unused and detailed information is not displayed. (11) If the data acquired this time is stored in the past address information, go to step (12), otherwise, end as it is. (12) The above data is compared with the past address information for each address, and only addresses with different results are updated with new information.

[0010]

As described above, according to the present invention, by providing the address information list means by the address map, the address selection means, the communication means for obtaining the address information, and the display and storage means thereof, the use address can be grasped, In addition to checking address setting errors in a short time and with a simple operation,
Even if you do not perform verification, you can immediately see the verification results up to the previous time.
