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 on a bus.

[0002]

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

[0003]

However, in the above-described configuration, it takes time to check the address setting status after the device is connected to the home bus, and the accuracy is lacking. In addition, the management of the history of address setting depends on the contractor. In this case, when a trouble occurs, it is considered that considerable effort and time are required until the cause of the trouble is specified. At the time of setting the address, it is preferable to inform the contractor of at least the information on the address already used and the presence or absence of an IFU abnormality.

SUMMARY OF THE INVENTION [0004] In view of the above problems, an object of the present invention is to provide an address verification device capable of listing address setting statuses and acquiring address information including past ones by a simpler operation. .

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an address verification device of the present invention transmits a message to each device to check the connection status with various devices, and detects a response to the message. Communication means, address information display means for displaying address information, which is detailed information on the address use status, assigned to the response, and address information storage capable of displaying the acquired address information as past data at a later date Means for comparing past data with current address information and displaying a matching result.

[0006]

The present invention operates as follows with the above-described configuration. It is assumed that various devices to be controlled and a device connection status verification device are connected to a transmission path via an interface unit (hereinafter, referred to as an IFU). When an address verifying device is operated after selecting an arbitrary address, each IFU having an address connected to the home bus is communicated one by one in order to verify whether the address is used. Go on. When the communication is completed, the use / unused 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 result of comparison with the address information obtained in the past are displayed. Is done.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An apparatus connection status verification apparatus according to one embodiment of the present invention will be described below with reference to the drawings. FIG. 2 shows a configuration 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 (hereinafter, referred to as an interface unit) connecting the transmission line 1 and the device connection status verification device 8.
IFU), 9, 10, and 11 are telephone sets, respectively.
Home automation devices such as fire sensors and home bus controllers.
5 is connected to the transmission line 1. Unused IFUs 6 and 7 are not connected. It is assumed that addresses are assigned to the respective IFUs so as not to overlap with each other.

FIG. 1 is a block diagram showing the configuration of a device connection status verification device according to an embodiment of the present invention. The CPU 12
It controls the operation of each of the following 13 to 17 means. The address information list means 13 comprises a user interface, and displays each address on the home bus in a map form. The address selecting means 14
The user interface is the main unit, and the address is selected by moving the cursor by using the address information list unit 13 in the sense of a map. The communication means 15 includes, via the IFU 2, a device connection status verification device,
This is a means for transmitting and receiving electronic data packets to and from the home bus, and FIG. 5 shows 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 has a start bit, a parity bit,
It has an 11-bit configuration including a stop bit.
The address information display means 16 is a means for processing the address information obtained by the communication means 15 into a form effective for the user and displaying the processed information. Address information storage means 17
Is means for accumulating newly acquired address information as data with respect to 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) An arbitrary individual address, all addresses included in a specific group, or all addresses are selected by the cursor. (4) If all addresses have been selected, go to step (6); otherwise, go to (5). (5) If you have finished selecting any address, go 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) The verification device sends a message having an “attribute request” command to one selected address, and obtains address information based on the result. Figure 4 shows the procedure for setting
Explained). (9) Terminate the communication. (10) The address information obtained in the above steps is the name and attribute of the home automation device connected to the home bus, the comparison result with the data stored in the past,
Are displayed in the form of items. At the time of address selection, home automation devices 9, 10, 11
Is selected, the address is used and the detailed item is displayed. If an address of an unused IFU 6 or 7 is selected, the address is determined to be unused and no detailed information is displayed. (11) If the data acquired this time is to be stored in the past address information, the process proceeds to step (12). If not, the process ends. (12) The data is compared with past address information with respect to each address, and only addresses having different results are updated with new information.

[0010]

As described above, the present invention provides an address information list means based on an address map, an address selection means, a communication means for acquiring address information, and a display and storage means therefor, so that the use address can be grasped, Checking for address setting errors can be performed in a short time and with simple operation.
Even if no verification is performed, the results of the previous verification can be immediately viewed.
