Abstract

PURPOSE:To completely cancel a double setting and to further simply cancel an address double information even at the time of erroneously executing the double setting of a self-station address by providing a reception self-station address detecting means, an address double informing means and an arithmetic control means. CONSTITUTION:At the time of erroneously duplicating and setting the self-station address, when one of communication terminal equipments set to the self-station address transmits, the communication terminal equipment set to the other same self-station address receives a signal by a communication means 2. Then, the self-station address in the signal is detected by the reception self-station address detecting means 5 to detect that it is the same as a self address set by a self- station address setting means 3 by a comparison detecting means 6 and the arithmetic control means 9 controls an address double informing means 4. Thereby, the generation of the address double is instantaneously understood and the address double information can be easily cancelled by changing the setting of the self-station address.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to communication terminal equipment in a system that performs communication control between communication terminal equipment distributed in a distributed manner.

Conventional technology In recent years, for the purpose of centrally controlling multiple communication terminal devices or monitoring the status of communication terminal devices, communication terminal devices have been connected with electrical transmission channels to transmit signals to each other. Various transmission control methods have been reported. - For example, there is a method of using electric light lines as a transmission communication channel to control electrical appliances in a general household. This is a system that superimposes a communication signal voltage of a sufficiently higher frequency on top of the AC voltage on the power line to communicate between each communication terminal device, and because it does not require special wiring for control, it is easy to install. It has the characteristic of requiring little effort and cost.

In this system, each communication terminal device has its own address, and when a transmission request is made to another communication terminal device, a command is issued that gives the own station address, the other station address indicating the destination, and a command to send data. A signal consisting of Then, other communication terminal equipment that receives this compares the other station address included in the received signal with its own station address, and if they are different, ignores the command in this signal, and if they match. If so, it sends back a confirmation signal that it has received the signal normally, and performs operations according to the commands in the signal.

Normally, in this system, multiple communication terminal devices having the same local address should not exist.

This is because if a communication terminal device sends a message to multiple communication terminal devices that have the same local address, the confirmation signal used to improve communication reliability will be duplicated. The item will be returned, and its reliability will be compromised. In addition, if a communication terminal device monitors and displays the operating status of a communication terminal device with a specific address, and there are multiple communication terminal devices whose own address is the address to be monitored, those multiple communication When each terminal device operates differently, the monitor display becomes confused. However, during construction of this system, the home address of each communication terminal device is manually set one by one, so multiple devices may be set to the same home address due to incorrect settings, which can cause problems in the entire system. It often interferes with movement. In this case, the conventional method has been for the operator to check the local address of each communication terminal device one by one and reconfigure the local address of the communication terminal device that was incorrectly set.

Problems to be Solved by the Invention However, with the method described above, when there are a large number of configured communication terminals, not only does it take a lot of time to search for incorrectly configured communication terminals, but it also completely confuses the user's own address. In the worst case scenario, enforcement may end without being able to remove duplicate settings, causing inconvenience to users.

The present invention solves this problem, and even if duplicate addresses are set by mistake during the construction of the system described above, the duplicate settings can be canceled quickly and reliably, and furthermore, address duplication can be notified. The purpose of the present invention is to provide a communication terminal device that can easily cancel the notification even after the notification has been made.

Means for Solving the Problems To achieve this object, the communication terminal equipment of the present invention includes a communication means for transmitting and receiving signals on a transmission communication path, an own address setting means for setting its own address, and the above-mentioned communication terminal equipment. address duplication notification means for notifying that a plurality of communication terminal devices having the same own address as the address set by the own address setting means exist on the same transmission communication path; and a transmission communication path received by the communication means; receiving own address detecting means for detecting the own address of the signal, and comparing the address detected by said receiving own address detecting means and the address set by said own address setting means to confirm that they are the same. A comparison detection means detects, decodes a signal obtained by the communication means, and controls transmission of the communication means, and the comparison detection means detects whether communication terminal equipment having the same local address as its own address is the same. The address duplication notification means is controlled to notify the address duplication when the presence on the transmission communication path is detected, and the address duplication notification is controlled to cancel the address duplication notification when the setting contents of the local address setting means are changed. and arithmetic control means for controlling the duplication notification means.

Effect With this configuration, when configuring a system using this communication terminal equipment, even if you mistakenly set the own address twice, one of the communication terminal equipment set to that own address will not be able to transmit. For example, a communication terminal device that is set to the same own address as another one receives the signal through the communication means, detects the own address in the signal using the received own address detection means, and determines whether it is the own address. The comparison detection means detects that the address is the same as the own address set by the address setting means, and as a result, the arithmetic control means controls the address duplication notification means to notify of address duplication. This can be immediately recognized, and the address multiplex notification can be easily canceled by changing the setting of the local station address.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2. FIG. 1 shows an internal configuration diagram of a communication terminal device according to the present invention. In FIG. 1, 1 is a power line which is a transmission communication path, 2 is a communication means for transmitting and receiving signals on the power line 1 which is a transmission communication path, 3 is an own address setting means for setting its own address, and 4 is a communication means for transmitting and receiving signals on the power line 1 which is a transmission communication path. address duplication notification means for notifying that a communication terminal device having the same own station address exists on the same power line 1; 6 detects the own station address of the signal on the power line 1 received by the communication means 2; 6 is a comparison detection means for comparing the address detected by the receiving own address detecting means 6 and the address set by the own address setting means 3 and detecting that they are the same; 7; is a load change request input means for requesting a load change of 0N10FF, and 8 is a load ON/○
FFN/upward load control means 9 decodes the signal obtained by the communication means 2 and controls the transmission of the communication means 2, and also controls the address duplication notification means 4, and receives a load change request of 0N10FF as a load change input. arithmetic control means for controlling the load control means 8 when a change occurs in the means 7; 9-a is a change detection section for detecting a change in the setting of the local address; e-b;
Reference numeral 10 denotes a set unit that controls the address duplication notification means 4 to perform address duplication notification, 9-a a reset unit that controls the address duplication notification unit 4 to cancel address duplication notification, and 10 a communication terminal device.

The operation of the communication terminal device configured as described above will be explained below. Now, assume that another communication terminal device having the same local address as this communication terminal device 10 transmits a signal on the power line 1. This signal is received by the communication means 2, and the own station address contained therein is detected by the receiving own station address detection means 6, and this signal is the same as the own address set by the own station address setting means 3. The comparison detection means 6 detects, and as a result, the arithmetic control means 9 detects the same lamp! The set unit 9-b controls the address duplication notification means 4 to notify that there is a communication terminal device on the communication terminal 1 having the same local address as the communication terminal device 1. After this, the arithmetic control means 9 detects that the setting contents of the local address setting means 3 have been changed by the change detection section 9-a, and causes the reset section 9-Q to cancel the address duplication notification. Control 4. The above is an explanation of the main operations of the communication terminal device of the present invention.

In addition, from the load change request input means 7, the 0N10F of the load
F When a change request is made, or when a command for instructing a load 0N10FF change directed to the own station is received through the communication means 2, the arithmetic control means 9 instructs the load control means 8 to control the load 0N10FF. , the load status after the control instruction is transmitted onto the power line 1 by controlling the communication means 2. The load change request input means A also functions as an input for canceling address duplication notification. That is, when a load change request is received from the load change request input means 7 while the calculation control means 9 is controlling the address duplication notification means 4 to perform address duplication notification, the calculation control means 9 cancels the address duplication notification. The reset section 9-
The address duplication notification means 4 is controlled by d. The above is the internal operation of the communication terminal device according to one embodiment of the present invention.

FIG. 2 shows an example of a system configured by communication terminals according to an example of the present invention. In FIG. 2, reference numeral 1 denotes a power line which is a transmission communication path, and is the same as in FIG. 1
1 to 14 correspond to the communication terminal equipment 1o in FIG. 15
1 to 18 correspond to the own station address setting means 3 in FIG. 1, and are constituted by rotary switches here.

Reference numerals 19 to 22 are electric appliances that are loads, and each of them has a power rating of 0N10 depending on whether or not it receives power from the communication terminal equipment 11 to 14.
FF controlled. Reference numerals 23 to 26 are LEDs, which correspond to the address duplication notification means 4 in FIG. 1, but here they normally operate to display the 0N10FF status of the electric appliances 19 to 22. 27-3 corresponds to the load change request input means 7 in FIG. 1, and here it is constituted by a switch. Reference numeral 31 denotes a controller, which remotely controls the communication terminal devices whose own station addresses are Nos. 1 to 4 via the power line 1, thereby controlling the electrical appliances connected thereto, and also monitors their 0N10FF status. .

32 to 36 are LEDs, which are 0N of electric appliances connected to communication terminal equipment having own station addresses of 1 to 4 in order.
10FF status is displayed. 36 to 39 are switches, which operate as remote control request inputs for communication terminal equipment having own station addresses 1 to 4 in order, and each time the switches are pressed, the controller 31 displays the electrical appliances indicated by the corresponding LEDs. It operates to invert the state of .

The operation of the system configured as above will be explained below. First, assume that the switch 36 is pressed. If the LKD 32 is displaying ON at this time, the controller 31 sends a signal to the power line 1 consisting of its own address, number 1 which is the partner station address (own station address of the communication terminal equipment), and an OFF control command. Send to. Then, since the rotary switch 16 for setting the own station address of the communication terminal device 11 is set to No. 1, the communication terminal device 11 returns a confirmation signal that it has received the signal normally, and also responds to the command in this signal. Turn off electrical appliances 19 according to
F control, and the OFF state after that control is controlled by controller 3.
Send to 1. The controller 31 that receives this signal via the electric light line 1 turns on the electric appliance 19 by means of the LED 32.
OFF display. Similarly, when the switch 37 is pressed, the electric appliance 2o is reversely controlled. When the switch 38 is pressed, transmission is performed to the communication terminal device whose own address is number 3, but both the communication terminal equipment 13 and the communication terminal equipment 14 whose own address is rotary switch 1.
7.18, this signal is received at the same time, and the confirmation signal, which is originally intended to improve the reliability of communication, is sent back duplicated, resulting in a loss of reliability. Put it away. Further, when the 0N10FF states of the electric appliance 21 and the electric appliance 22 are different, the display on the LEDs 4 becomes confusing. However, in this system, as explained using FIG. 1, when a communication terminal device with an address duplication transmits a signal, it is immediately revealed that an address duplication has occurred.

For example, if the communication terminal device 14 transmits a signal onto the power line 1, the communication means in the communication terminal device 13 receives the signal,
Address duplication is detected by the reception own address detection means, comparison detection means, and own address setting means, and the LED 25 of the communication terminal device 13, which normally displays the 0N10FF status of the electric appliance 21, issues an address duplication notification ( (for example, flashing).

Similarly, when the communication terminal device 13 transmits a signal onto the power line 1, the LED 26 of the communication terminal device 14 notifies the address duplication. Also, cancellation of this address duplication notification is very simple, as it only requires changing the own address as explained in FIG. Therefore, even if you mistakenly set a duplicate local address on a communication terminal device during system installation, you can quickly and reliably cancel the duplicate setting.Furthermore, you can easily cancel the duplicate address notification even after it has been notified. The Rukoto.

Note that in this communication terminal device, among the communication terminal devices that caused the address duplication, the communication terminal device that transmitted the signal cannot notify the address duplication. To explain this using FIG. 2, the communication terminal devices 13 and 1 with duplicate addresses
4, if communication terminal device 13 transmits, communication terminal device 1
4 only performs address duplication notification. Therefore, if you try to make the communication terminal device 13 that first transmitted the signal notify the address duplication, the communication terminal device 14 will notify the address duplication by the signal from the communication terminal device 13, and the other It is sufficient to send an address duplication command to the communication terminal equipment over the power line 1. Then, the communication terminal device 13 detects that its own address contained therein is equal to its own address set by the rotary switch 18, and uses the LED 25 to notify the address duplication. In the above operation, the arithmetic control means 9 in FIG.
When it is detected that there is an address on the power line 1, the set unit 9-b controls the address duplication notification means 4 to notify the address duplication, and also communicates to send an address duplication command on the power line 1 to notify the address duplication. This can be realized by controlling means 2.

Further, when both the communication terminal devices 13 and 14 in FIG. If the settings of communication terminal device 1 are changed, that is, if the own station address is changed,
3 stops the blinking of the LED 25 and transmits a duplicate address change command indicating that the address that caused the address duplication has been changed on the light #j1, and the communication terminal device 14 that receives this stops the address duplication notification, In other words, L
There is a way to stop the ED26 from blinking.

This means that when the arithmetic control means 9 in FIG. 1 is controlling the address duplication notification means 4 to notify of address duplication, the change detection section 9-a detects that the setting contents of the local address setting means 3 have changed. When the address duplication is detected, the reset unit 9-c controls the address duplication notification means 4 to cancel the address duplication notification, and sends out a duplicate address change command indicating that the address that caused the address duplication has been changed. controlling the communication means 2 to transmit on line 1; Then, when the arithmetic control means 9 receives a duplicate address change command through the communication means 2 while the set section 9-b is controlling the address duplication notification means 4 so as to notify the address duplication, the reset section 9 This can be realized by controlling the address duplication notification means 4 to cancel the address duplication notification at -c.

As a second method, for example, the controller 31 transmits an address duplication notification cancellation command to the power line 1, which instructs to stop address duplication, and the communication terminal equipment 1 that receives this command
3.14 has a method to stop address duplication notification. This occurs when the arithmetic control means 9 in FIG. 1 receives an address duplication notification cancellation command through the communication means 2 while the set unit s-b is controlling the address duplication notification means 4 to notify of address duplication. This can be realized by controlling the address duplication notification means 4 so that the reset unit 9-c cancels the address duplication notification.

Note that the load change request input means 7 and load control means 8 in FIG. 1 are shown because they are necessary for the explanation of FIG. 2, and are not directly related to the gist of the present invention. Therefore, this communication The operation of the terminal device can be realized by all devices connected to the same power line, such as the controller 31.

Furthermore, although power lines are used as transmission communication channels here, other transmission communication channels such as coaxial cables, dedicated communication lines,
Alternatively, the idea of the present invention can also be adopted in a system that uses radio waves, infrared rays, or other radio waves.

Note that the three operations of the reception own address detection means 6, comparison detection means 6, and arithmetic control means 9 in FIG. 1 can be realized by one microcomputer. The device includes a communication means for transmitting and receiving signals on a transmission communication path, a own address setting means for setting its own address, and a communication terminal having a own address that is the same as the address set by the own address setting means. address duplication notification means for notifying that devices exist on the same transmission communication path; reception own address detection means for detecting the own address of a signal on the transmission communication path received by the communication means; and the reception own address. Comparing and detecting means for comparing the address detected by the detecting means and the address set by the own station address setting means and detecting that they are the same, decoding the signal obtained by the communication means, and the communication When the comparison detection means detects that a communication terminal device having the same local address as its own address exists on the same transmission communication path, it cancels the address duplication notification. By having arithmetic control means for controlling the address duplication notification means, even if the self-station address is set to be duplicated by mistake, the communication terminal device with the duplicated address can be quickly and reliably searched. Duplicate settings can be completely canceled, and even after address duplication notification has been made, the notification can be easily canceled, which has great effects.
