Description

[Detailed description of the invention] [Table of contents] Overview Industrial field of application Conventional technology Problems to be solved by the invention Means for solving the problems (Fig. 1) Working examples (Figs. 2 and 3) Effects of the invention [Summary] Regarding a device number assignment method, the purpose is to automatically allocate serial device numbers to a plurality of devices in sequence, and to allocate serial device numbers to each of the devices in a system in which a plurality of transmission devices are connected. In the device number assignment method, the monitoring device sends a signal containing the first numerical value of the device number to the first device to be assigned a number, and the device that receives this signal sets this as its own device number and also assigns this device number. A serial device number is automatically assigned to each device in sequence by sending a signal containing a device number obtained by adding 1 to the adjacent device to the adjacent device.

[Industrial application field]

The present invention relates to a device number assignment method, and more particularly to a device number assignment method that can automatically assign different serial device numbers to each transmission device terminal device and the like constituting a system.

[Conventional technology]

Conventionally, in order for an SV (supervisor) system device to know the status of each device in a station or transmission system, it specifies a preset individual device number and makes an inquiry. recognized its own device number and responded.

In such a case, it is necessary to assign the device number of each device to the SV system device in advance as a serial number in a heart-like manner.

In other words, the settings are usually made using a DIP switch or the like within the device, and even when it is done using software, the operator has to make the allocation settings himself.

[Problems to be Solved by the Invention] The conventional devices as described above have the following drawbacks.

(1) When adding or subtracting devices, it is necessary to go to the location where the devices are installed and change device number settings manually, which takes time and effort.

(2) The number of parts in the device increases.

The present invention has been made in order to solve the above-mentioned drawbacks of the conventional technology, and aims to make it possible to easily and automatically allocate serial device numbers even when adding or reducing the number of devices. That is.

[Means to solve the problem]

- In order to achieve the object set forth in F, the present invention is as follows.

FIG. 1 is an explanatory diagram of the principle of the device number allocation method according to the present invention, and the principle of the present invention will be explained below based on this diagram.

In the intra-office connection as shown in the figure, the monitoring device SV assigns numbers at the initial stage (when the power is turned on) or at a constant 1υ1.

First, from the monitoring device SV, the initial value of the device number ro
oIJ is concatenated with (, L) indicating that this signal is the device number and transmitted. Note that the number rooIJ is 1
This is an example. It doesn't have to be 3 digits.

This transmission is performed by the first one of the plurality of transmission devices connected in series.
This is done for the transmission device set as the second device.

The transmission device that receives r 001 and J writes roolJ in its own internal memory (RAM).

Apart from the dirt, 1 is added to this received numerical value r001J to form ro O2J, which is then transmitted to the adjacent device.

Similarly, the transmission device that receives the received numerical value r K j writes rKJ into its own internal memory and adds 1 to rKJ to make rK+IJ and transmits it to the adjacent device.

For the last device, set "K+1" to the setting number of the own device, and r
K+2J is transmitted to the monitoring device SV via the SV signal line.

In the monitoring device SV, this finally transmitted numerical value rK+
It is also possible to receive 2J and automatically know the number of devices in the station, including S■ devices, based on this.

(Number of devices: +2) Also, for the monitoring device, the number of devices learned as above is
It can be used for monitoring, or sent to a display device and displayed for maintenance and operation.

[Effect]

With the above configuration, the monitoring device S can automatically assign device numbers to multiple cascaded transmission devices by simply sending, for example, roolJ as the initial value. Can be done.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.
The figure is an explanatory diagram of a device number allocation method that is an embodiment of the present invention.

The monitoring device SV includes an initial device number generation section 1, a transmission signal generation section 2, and a decoding section 3 for decoding received signals.
, a device number extraction section 4, and a control section 5 are provided.

Each transmission device also includes a decoder 6 for decoding the received signal.
, number notification signal storage section 7, device number extraction section 8, device number storage section 9, memory (RAM) 10, +1 addition section 1),
A transmission signal generation section 12 is provided.

Each transmission device is connected in cascade,
It is monitored by a monitoring device SV.

Transmission devices within stations connected in this way can be expanded or
Or it may be reduced.

Even in such a case, serial device numbers are always assigned according to the order in which they are connected, for example, device numbers 1, 2, and 3.

Device numbers may be assigned not only when the number of transmission devices is increased or decreased, but also at an initial stage such as when the power is turned on, or periodically.

Automatic assignment of device numbers is performed as follows.

First, in the monitoring device SV, the initial device number generation unit 1
generates an initial device number, for example roolJ.

This number r001J is sent to the transmission signal generation unit 2, where rroolJ is concatenated with the number notification code "x
Create a transmission signal like 01J.

This transmission signal is sent to the first device to be set among the transmission devices.

In the transmission device that receives the signal rxxxo 01J, the decoder 6 decodes it.

As a result of decoding, if it is found to be a device number setting signal, the j'-xxxJ portion of the signal is stored in the number notification signal storage section 7, and the device number extraction section 8 extracts the device number. Extract a certain "001".

The extracted signal roolj is written into the memory (RAM) 10 and used as the device number of the own transmission device.

Separately, the extracted signal r001J is sent to the +1 adder 1), where +1 is added to it and transmitted as "002".
It is sent to the x issue creation department I2.

Here, the signal stored in the number notification signal storage section 7 "
×××” to the transmission signal generation unit 12, and the above signal ro
02J and is the transmission signal to the adjacent device [-×
XX002-1 is created and sent to the adjacent device.

Next, in the transmission device that received rxxxxo02J, ro
Set 02J to the device number of the own device, and send the transmission signal rx
Create xx003J and send it to the adjacent device.

Thereafter, device numbers are set (up to K+1) in the same manner, and the transmission signal from the last transmission device is sent to the monitoring device SV via the SV signal line.

In the monitoring device SV, the received signal is interpreted by the decoder 3.

As a result, it is detected that the assignment of device numbers to the transmission devices has been completed, and the device number extraction section 4 extracts the device number and sends this number to the main control section 5. The main control unit 5 can automatically know the number of devices in the station based on the noise.

Also, at this time, the number of devices in the station can be sent to a display device (not shown) and displayed.

In this way, it becomes possible to allocate device numbers in an orderly manner without performing hardware settings in advance.

FIG. 3 shows an example of application of the present invention, and is an example in which the device numbers of the entire system J can be automatically assigned by combining the above two inventions.

In the figure, SVo is a center monitoring device, and is a device that monitors the entire system.

SV+ to SVa are monitoring devices in each station,
TE is a terminal device, and REG is a relay device.

First, numbers are assigned to the monitoring devices SVI to SV4 through the SV signal line in response to a signal from SVo.

For example, the SVr of station 1 is “001” and the SV2 of station 2 is “0”.
02", SV3 of station 3 is "003", SVa of station 4 is "
'004'.

Next, device numbers are assigned at each station.

For example, in station 1, LTE is routed to roo using SV+.
lJ, ro 02J, and in station 3, by SV3, REG is set to roolJ, and then LT
Assign E like ro 02J, ro O3J.

In this case, for example, the relay device REG in station 2 has the following information:
Assign the number r002001J to the REG of station 3.
is assigned the number r003001J.

In this way, the AA device number for the entire system can be automatically assigned, and each device number can be recognized from the SV level.

〔Effect of the invention〕

As explained above, the present invention has the following effects.

(1) There is no need to install numbered parts in each device,
・Also, there is no need to allocate and set it in advance.

(2) Since numbers are assigned by wiring, numbers can be automatically assigned in a good order even when adding transmission equipment.

(3) Since a serial device number can always be assigned, maintenance personnel can also easily use it.
