Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the collection of abnormal points when a call is not made to the callee.

[0002]

2. Description of the Related Art For example, in a gas leak alarm system shown in FIG. 5 for monitoring a gas meter with a microcomputer (hereinafter simply referred to as a gas meter), for example, a bidirectional automatic notification device (hereinafter referred to as a transmission controller) is provided outside each home. Installation, a telephone and a gas meter are connected to the transmission controller 3 or the transmission controller 6, and the operator inputs the telephone number of the transmission controller 3 or the transmission controller 6 on the center side and performs polling from the exchange 1 to the exchange 2
Alternatively, the transmission controller 3 or the transmission controller 6 is called via the exchange 5 for communication.

This communication is generally performed by ringing communication in which a telephone bell does not ring, and a ringing number for a ringing incoming call (hereinafter referred to as NRT) connected to an exchange (a local number + a local number + XX). XX) + the subscriber number (local number + XXXXXX) of the terminal for Norlingin is performed in front.

Further, the call of the transmission controller sends a hook signal (current flowing each time the line to the exchange is closed) to the exchange 1, and a dial tone is transmitted to the exchange 1.
Then, the above telephone number is transmitted.

In general, the exchange 1 stops transmission of a dial tone if any number is sent if it is normal.

Further, the transmission controller 3 and the transmission controller 6 are preset by the center with a date and time for reporting the meter reading data and the like. At this set date and time, the transmission controller calls the center and when there is a response, the gas meter In the same manner as described above, the hook signal is transmitted to the exchange 2 or the exchange 5 when transmitting the meter reading data, or when responding to the test notification on the center side, or when the switch for the test notification is pressed.

Then, the exchange 2 or the exchange 5 transmits a dial tone to the transmission controller side, and after confirming that there is a dial tone, the transmission controller transmits the telephone number of the center side to establish a line connection with the center side. After the status is reached, the data is transmitted.

[0008]

However, when the transmission controller sends a dial tone from the exchange,
Since the center's telephone number is automatically sent immediately, if the line cannot be connected even if the telephone number is sent, I do not know whether the center side is abnormal, the exchange side is abnormal, or the telephone line is abnormal. There was a problem.

Further, if the line is not connected to the report destination, the center side displays the report destination on the screen, and the operator waiting on the center side makes a telephone call to the report destination. By checking if there is a dial tone, or if the dial tone is gone when you send the digits in the phone number,
You can see whether the switch is abnormal or the line to the switch is abnormal. However, since there are usually no humans in the place where the transmission controller is attached, there was a problem that even if the center side knew that the line was not connected at the time of calling, it could not be helped.

The present invention has been made in order to solve the above problems, and it is possible to take prompt action by collecting data capable of automatically determining an abnormal place when a call is not taken or before making a call. The purpose is to obtain a method of collecting abnormal points of automatic notification and an automatic notification device.

[0011]

According to a first aspect of the present invention, when two-way communication is performed with a report destination connected to a telephone line, if the telephone line is open, the telephone line is connected to the report line to obtain report data. In the automatic transmission / reception method, when a tone signal is received due to the closing of a telephone line, a step of transmitting a one-digit dial number based on a setting order and a step of transmitting the one-digit dial number each time In addition, the process of opening the telephone line and closing the telephone line along with the transmission of the dial number, and the presence or absence of a tone signal as a result of the transmission inspection of the dial number each time the transmission of the one-digit dial number is completed. A step of storing, a step of executing each step until the transmission of all dial numbers is completed, and a response to a stored information read command after completion of the execution of each step,
The gist is to have a step of notifying this content.

Thus, when a telephone call is made or when no call is made, when the telephone line is open, the telephone line is closed and the line is connected, and the presence or absence of the tone signal transmitted at this time is stored.

When there is a tone signal, the one-digit dial number based on the set order and the presence or absence of the tone signal are stored, and the process of opening the telephone line is completed until the transmission of the last one-digit dial number is completed. Be implemented.

Next, when there is an instruction to read the stored contents, the collected stored contents are notified, so that it is possible to know why the call cannot be made.

According to a second aspect of the present invention, when the report destination is the master station and the device serves as a terminal for two-way communication, the master station sends a command to the terminal to inspect the transmission of the dial number, and the predetermined number is determined. After a lapse of time, send a command to read the stored information of the terminal,
The gist of the terminal is that it has a step of activating each step immediately when there is an instruction to request transmission inspection of a dial number from the master station or the operating means of the terminal.

As a result, the master station causes the terminal to collect the dialed numbers when the call is made or when the call is not taken, and after confirming the collected inspection results, the call is made.

According to a third aspect of the present invention, when performing two-way communication with a report destination, a telephone line is connected when the line is open, and a transmitter / receiver unit for transmitting and receiving the report data of the connected measurement meter is provided. , In the automatic notification device that is a terminal for the callee, the transmitter / receiver determines whether there is a tone signal when the telephone line is closed, and the one-digit dial number is sequentially sent from the transmitter / receiver based on the set order. It determines the dial number sending means to send and whether or not the transmission of the one-digit dial number is completed, and when it is completed, the telephone line is opened, and the telephone line is connected with the transmission of the one-digit dial number. Every time the transmission of the line opening control means for closing the circuit and the transmission of the one-digit dial number is completed, the presence or absence of a tone signal is read from the dial number transmission means, and the dial number corresponding to each digit is set. A number transmission result collecting means for storing in the memory as a result of signal test, the operating means report destination or the device, when the instruction is dispatched to perform transmission inspection,
Until the transmission of all dial numbers is completed, the collection command means for activating each means, and the instruction for reading the stored contents after each means is activated and the transmission result is collected are the notification destination or the operating means of the device. When sent by
The gist is that a collection data output means for notifying this content is provided.

Thus, when the transmission / reception unit does not make a call to the callee or makes a call, if the telephone line is open, the collection instruction unit causes the transmission / reception unit to close the telephone line, and dial number transmission unit or line opening. The control means and the number transmission result collection means are activated.

At this time, the presence / absence of a tone signal to be transmitted to the exchange is stored in the memory by the number transmission result sending means, and if there is a tone signal, the collection instruction means continues the activation, and the one-digit dialing based on the set order. When the number is transmitted, the line opening control means opens the telephone line, and the presence or absence of the tone signal at this time is stored by the number transmission result sending means until the end of transmission of the last digit digit number. To be done.

Since the collected data output means is informed of the collected memory contents by a command from the report destination or the operation means of the device, what should be done immediately by the worker of the report destination or the device. I know how.

According to a fourth aspect of the present invention, the collected data output means prints or displays the stored contents, or simultaneously prints and displays the stored contents, according to a command from the report destination or the operating means of the device.

As a result, the inspection result of the dialed number can be known to both the callee and the worker at the site.

A fifth aspect of the present invention is characterized in that the dial number transmitting means causes the transmitting / receiving section to transmit the telephone number of the report destination when all the one-digit telephone numbers are normally transmitted. As a result, the user does not need to make a phone call, and power consumption is suppressed.

According to a sixth aspect of the present invention, when the report destination is the master station and the two-way communication is performed using the device as a terminal with no ringing, the transmitting / receiving unit connects the master station with the line with no ringing and performs the two-way communication. Use as a summary.

Thus, the inspection result can be sent out in response to the response from the master station without ringing, and the master station also receives the inspection result from the terminal without ringing.

An answer is returned via the no-ringing communication circuit, and when communicating with the center, communication is performed via the terminal calling circuit 22 on the center side.

Reference numeral 25 is a no ringing communication circuit. The no-ringing communication circuit 25 is in a semi-closed state (hereinafter referred to as a half-operating state) due to the polarity reversal of the line, and when the no-ringing communication instruction is given from the computer, the half-operating state is changed to the operating state, and data is exchanged with the modem 23. And communicate with the other party.

The rectifying circuit 20 and the line connecting circuit 2 are also provided.
1, the no-ringing communication circuit 25, the terminal calling circuit 22, the modem 23 and the like are used as the transmitting / receiving section.

Reference numeral 26 is an off-hook detection circuit. The off-hook detection circuit 26 is connected to a telephone line and a home telephone,
Detects off-hook phone and informs computer.

27 is a 16 Hz polarity reversal detection circuit. The 16 Hz / polarity inversion detection circuit 27 is internally provided with a high impedance resistance element and is connected in parallel to the telephone line.

Reference numeral 28 is a computer unit (hereinafter referred to as MPU). The MPU 28 inputs the output signals from the off-hook detection circuit 26 and the 16 Hz / pole inversion detection circuit 27, and when it judges that it is the extreme, it activates the no-ringing circuit 25 and turns on the relay 24 to operate the modem 23. After that, it is determined whether or not the NRS is received, and when the NRS is received, the no-ringing communication circuit 25 is activated.

Further, the MPU 28 determines whether or not the dial tone signal from the exchange 2 has been received in accordance with the closed circuit of the line connected to the telephone line, and 0, while receiving the dial tone signal, Dial number sending means for sequentially sending the one-digit dial numbers 1, 2, ... 9 through the modem 23 and the no ringing communication circuit 25, and 0, 1,
It is judged whether or not the transmission of the one-digit dial number 2 ... 9 is completed, and when it is completed, the internal line connected to the telephone line is opened and the line is transmitted while the one-digit dial number is transmitted. When the transmission of the hook signal or the one-digit dial number is completed and the line opening control means for closing the line is read from the dial number sending means,
The number transmission result collecting means stored in the memory in correspondence with the hook signal and dial number, and when the callee is not called or when making a call, if there is a hook signal, all single digit dial numbers are sent. Until the end
When there is a collection command means for activating each means and an instruction to read the contents of the memory after each means is activated and the transmission result is collected, it responds with no ringing and sends out and informs the contents. At least a collection data output means is provided. Further, a display and a printer are connected to the collected data output means.

Further, when the center side performs bidirectional communication as the terminal, the center sends a command to the terminal to inspect the transmission of the dial number, and after a predetermined time elapses, the stored information of the terminal is stored. Send an instruction to read.

The operation of the automatic notification device configured as described above will be described below. For example, the telephone is off-hook and has a noring communication service.

When the MPU makes a call to the center from its own station (including when the switch for resending and test notification is pressed by the worker), the MPU gives a test notification from the center or a notification factor such as the meter reading date and time. Determine whether it has occurred (S
301). In this example, a notification factor of a response to the test notification on the center side will be described.

Next, when it is determined that the report factor has occurred, the output signal from the off-hook detection circuit 26 is read to determine whether the telephone is in use (S303). Next, when the telephone is not used, a control signal is output to the line connection circuit 21, the transistor is turned on to close the line, and the line loop up to the exchange 2 is closed to generate the hook signal. Output (S305).

Next, it is determined whether or not there is a dial tone signal (S307). That is, it is determined whether or not there is a dial tone from the exchange 2 after closing the line.

Next, when it is determined that there is a dial tone, for example, the telephone dial number i (i = 0, 1, 2,
...... 9) "0" is sent (S309). Then, it is determined whether or not there is a dial tone (S311), and when there is a dial tone, the fact that there was an error even if the dial number "0" was sent is written and stored in the transmission result table of the memory ( S313). In other words, it is understood from this transmission result that the number i may not be transmitted from the controller. The transmission result table is, for example, as shown in Table 1.

[0039]

[Table 1] Next, the control signal to the line connection circuit 21 is stopped, the line is opened to open the line loop (S315), and it is determined whether the dial number i is "9" (S31).
7) If the dial number i is not "9",
The dial number i is updated (S319), control is transferred to step S305, the line is closed again, the updated next dial number i (i = i + 1) is sent, and the presence or absence of a dial tone is written in the transmission result table. Put in. For example, if there is an error, a flag is set in the table.

When it is determined in step S317 that the dial number "9" has been transmitted, the line loop is opened and the processing is terminated (S321).

If there is no dial tone after closing the line loop in step S307, it is determined that there is no dial tone when the line loop is closed, an error flag is set in the table, and control is passed to step S321 to set the line loop. The circuit is opened (S323). In other words, when the line is closed, the exchange 2 did not output a dial tone, so it is clear that even if the dial number is transmitted, it will not be communicated, and the power will be wasted. To stop.

Then, by reading the contents of the memory later, it is later determined that the exchange 2 is abnormal, the line up to the exchange is abnormal, or the line of this controller is not properly connected to the line. It can be understood by reading the contents.

Further, when there is no dial tone after transmitting the one-digit dial number i in step S311, it is indicated in the transmission result table that the exchange 2 was able to receive at this dial number i, indicating that it is OK. A flag is set and control is moved to step S315 (S325).

Further, if it is determined in step S301 that the report factor is not generated, it is determined whether NRS is received (S327), and if NRS is received, it is determined whether it is the NRS of the device (S329). ). Then, if it is the NRS of the device, it is judged whether or not a transmission result request command has been received (S331), and when it is judged that the transmission result request command has been received, the contents of the transmission result table are sent to the communication destination in a predetermined message format. Send and end control (S
333).

Next, a sequence when the transmission controller operates based on the above flow will be described. FIG. 4 is a sequence diagram when the controller is abnormal. In this example as well, similarly to the above, the response is a test notification from the center.

As shown in FIG. 4, when the transmission controller receives a telephone call from the center side and the line is connected and there is a test request, the response to this test request is regarded as the generation of a report factor, and after the line disconnection from the center side, When the line is closed and the line loop is closed, a hook signal is output to the exchange 2, and if there is a dial tone, the line is closed and the dial number i is sent digit by digit as shown in FIG. Corresponding to the dialed number, the presence or absence of a tone is stored and the line is opened. In FIG. 4, since the controller is abnormal, the dial number i is not sent as shown by the dotted line.

Then, the center connects the transmission controller with a line, transmits a collection data read command, and transmits the collection data of the transmission result table.

Therefore, even if the center side makes a request for a test message, it can determine in response to the test message why the transmission controller that did not report could not report, so that the maintenance instruction can be promptly issued. . For example, if there is no tone signal for the hook signal, the exchange or the telephone line to the exchange is likely to be abnormal, and if the tone signal is still present when sending the one digit dialed number, The operator at the call destination can know that the calling function on the controller side is more abnormal than the exchange or telephone line, and what number is abnormal. You can see if you can't apply.

When it is not necessary to consider the power consumption, etc., when the center makes a call from its own station, the above processing is always executed to keep the transmission result table up to date. When the dial number i is correctly sent, the telephone number of the center may be transmitted by assuming that the telephone is available, and the medical examination data of the gas meter or the like may be transmitted.

In the above-described embodiment of the present invention, the present invention is applied to the no-ringing communication service, but it may be applied to the ringing communication.

Further, although the dial numbers are "0" to "9", they may include numeric keys "*" and "#" of the telephone.

It is also possible to connect a switch for reading the stored contents to the MPU 28, connect a display or a printer through an interface, and read the stored contents for printing or displaying when the switch is pressed.

[0053]

As described above, according to the first aspect of the present invention, the telephone line is closed when the callee is not called or when the telephone line is open. At this time,
After storing the presence or absence of a tone signal when transmitting a one-digit dial number based on the setting order and opening the telephone line until the transmission of the last one-digit dial number is completed, the stored contents By telling the collected memory contents when there is an instruction to read, the minimum required transmission result when making a call is collected, so you can understand why you can not make a call . Further, since it can be judged by the worker on site inputting the command, there is an effect that the maintenance instruction or the maintenance work can be promptly performed.

Further, when there is no tone signal, that is, when the exchange side is abnormal, the transmission of the one-digit dial number is not carried out, so that it is possible to obtain the effect of not wasting power.

According to the second aspect of the present invention, when the report destination is the master station and the apparatus acts as a terminal for two-way communication, if there is a command for transmission inspection of the dial number from the master station, the dial number immediately collected. By sending the inspection result of
Since the operator on the side of the master station can immediately understand what causes the communication failure, it is possible to know what kind of measures should be given to the workers on the site.

According to the third aspect, when the telephone line is open by the transmitter / receiver when the callee is not called or when making a call, the collection command means causes the transmitter / receiver to close the telephone line and dial the dialed number. The sending means, the line opening control means, and the number transmission result collecting means are activated. At this time, the number transmission result sending means stores the presence or absence of the tone signal from the exchange in the memory. When there is a tone signal, the one-digit dial number based on the setting order is executed up to the last one digit while continuing the activation of each means.

Then, when there is an instruction to read the stored contents by an instruction from the notification destination or the operation means, the collected contents are notified to inform the destination and the operator of the contents of this memory. As a result, it is possible to obtain the effect that the callee and the worker can know what causes the call cannot be reached.

According to the fourth aspect of the present invention, the operator can print or display the inspection result of the dial number and notify the report destination according to an instruction from the report destination or the report destination, so that the worker can detect the abnormal location at any time. In addition to being able to analyze the above, there is an effect that at the same time, it is possible to know what kind of abnormality is occurring even at the report destination, which is the parent station. According to claim 5, when the result of transmitting all the one-digit telephone numbers is all normal, the telephone number of the report destination is transmitted, so that it is possible to obtain the effect of not making unnecessary reports. .

According to the sixth aspect, when the report destination, which is the master station, calls the device with no ringing, the device receives with no ringing and reports the inspection result or the medical examination result. The effect of being able to do is obtained.
