In addition, information communication devices that communicate meter reading data with predetermined organizations such as gas companies are beginning to be put into practical use.

In addition, input to terminal devices such as initial data such as telephone number, meter reading information, etc. of the management center is performed by a setter which inputs the initial data to the terminal device when the terminal device is installed in the house.

In addition, the present applicant has proposed that after the transmission data is transmitted from the terminal device to the management center, the data retransmission request code is transmitted from the management center to the terminal device in the case of a mistake in the transmission data (Japanese Patent Application No. 60-251655). number).

However, at the time of installation of the terminal device, even if the initial data is inputted to the terminal device by the setting device and then immediately sent to the management center, there is no method of detecting the data sending instruction code from the management center on the setting party side. For this reason, when the meter reading information is transmitted from the terminal device to the management center after the setting of the initial data, the setter side can confirm that the line is connected incorrectly or the transmission data is wrong due to the input data error. There was no.

Therefore, a setting device capable of confirming whether or not the terminal device and the management center can communicate with each other when the terminal device is installed is desired.

The present invention provides an initial data setting apparatus for an information communication apparatus capable of confirming whether or not a terminal apparatus and a management center can communicate with each other at the time of installation of the terminal apparatus.

And a detection device for detecting whether the management center and the terminal device can communicate with each other.

When the initial data setting device of the information communication device of the present invention is installed in the terminal device, when the initial data is inputted to the terminal device by the setting device and immediately transmitted to the management center, the reception code from the management center is set as the return signal. Since it can be detected by the setter side, the terminal apparatus and the management center can reliably confirm whether or not a communication state is possible during initial data input.

Therefore, transmission control and reception control can be performed automatically at the sending company and the terminal device side of meter reading information or safety information, and also at the management center side, transmission control and reception control can be performed automatically. It is determined whether or not communication is possible between the terminal apparatus and the management center even if the terminal apparatus does not exist.

As shown in FIGS. 1 and 2, the setter 4 includes a push button 4l composed of numerals from 0 to 9, symbols of *, #, A, B, C, D, and the like on the surface thereof. A liquid crystal display (LCD) 42 and a display lamp 43, which is a detection device that lights when detecting a reception (#) code from the management center 3, are provided, and a lithium battery (5V) 44 is provided therein.

Normally, the voltage of the PB signal detection circuit 23j is boosted by the boosting circuit 23k to the "H" level (8V). Here, as described later, when the terminal apparatus 2 performs an operation of transmitting transmission data to the management center 3 experimentally and receives the # code from the management center 3 by the PB signal detection circuit 23j, The voltage drops from the "H" level (8V) to the "L" level (OV). At this time, the light emitting diode 45 of the #signal detection circuit 46 connected to the #signal connector 25a has a high level (5V) due to energization of the lithium battery 44 at the "L" level OV. Light emission. As a result, the display lamp 43 lights up, and the user can confirm that the # code can be received from the terminal 2 by the management center 3.

Therefore, when the terminal device 2 is installed by the # code detection circuit 46 and the display lamp 43, it is possible to detect a state in which the management center 3 and the terminal device 2 can communicate.

The operation of the # code detection system by the setter 4 of the present embodiment will be described with reference to the drawings.

3 shows an operational flowchart of the receiving code detection system. First, the telephone number or code number (for example, * 12) of the management center 3 is input to the terminal device 2 by the setting device 4 (step 101).

Subsequently, initial reading data such as initial data of the reading value of the gas meter GM is input by the setting device 4 of the terminal device 2 (step 102). As other initial data, a set value of the gas leakage flow rate, a transmission time of the gas meter reading information to the management center 3, a set voltage value of the power supply, a user's telephone number or code number, and the like are input.

In order to transmit the gas leak setting report to the management center 3, the gas leak sensor S1 is experimentally operated. That is, an output of 12V is generated from the gas leakage sensor S1 (step 103). A gas leakage signal 12V from the gas leakage sensor S1 is input to the CPU 22 via the interface 21 to detect gas leakage (step 104). Then, the transmission control subroutine of the gas leak setting report shown in FIG. 4 is executed (step 105).

4 shows a transmission control subroutine of this embodiment.

In order to judge whether or not the telephone T is in use, it is judged whether or not the line use detection circuit 23a detects a call mode (step 201). When the line use detection circuit 23a detects the call mode (Yes), step 201 is repeated.

When the line use detection circuit 23a does not detect the call mode (NO), it is determined whether or not the ring tone detection circuit 23b detects an incoming signal in order to determine whether an incoming call is being made from a telephone outside the house. (Step 202). When the ring tone detection circuit 23b detects the incoming call output (Yes), the step 201 is returned.

When the ring tone detection circuit 23b does not detect an incoming call (NO), it outputs to the line conversion relay 23e to close the contact 23g, opens the contact 23h, and opens the telephone public line L. And the PB signal generation circuit 23d are connected to connect the DC circuit 23f (step 203).

It is determined whether 3 seconds have elapsed after the DC circuit 23f is connected (step 204). When 3 seconds have not elapsed since the connection of the DC circuit 23f (NO), the step 204 is repeated. When 3 seconds have elapsed since the connection of the DC circuit 23f (Yes), the transmission code (for example, the telephone number or code number of the management center) is transmitted to call the management center 3, and the automatic dial (Step 205). In order to determine whether the # code, which is the data transmission instruction code, has been received from the management center 3 as the outgoing signal of the outgoing code, it is judged whether or not the PB signal detection circuit 23j has detected the # code (step 206). ). Here, the setter 4 is also monitored to detect the # code.

When the PB signal detection circuit 23j detects the # sign, that is, when the PB signal detection circuit 23j inverts from the "H" level 8V to the "L" level OV (Yes), management is performed. The transmission data for the transmission code is transmitted to the center 3 (step 207). Then, the PB signal detection circuit 23j is inverted from the "H" level 8V to the "L" level OV, so that the light-emitting diode 45 in the # sign detection circuit 46 of the setter 4 becomes a lithium battery. The display lamp 43 is turned on because the light is inverted from the " L " level OV to the " H " level 5V by the supply voltage of (44). Therefore, it is possible to confirm that the terminal device 2 can receive the # code from the management center 3 at the time of setting the terminal device 2.

In step 206, when the PB signal detection circuit 23j does not detect the # sign (NO), it is determined whether or not the number of times of transmission has been three times after autodial (step 208).

When the number of times of transmission is not three (NO), it outputs to the line conversion relay 23e, opens the contact 29g, closes the contact 23h, and closes the telephone line l of the telephone and the main telephone T. ) Is connected and the DC circuit 23f is opened (step 209).

Thereafter, it is determined whether or not five seconds have elapsed (step 210). When 5 seconds have not elapsed (NO), step 210 is repeated. When 5 seconds have elapsed (Yes), step 201 or less is repeated again.

When the number of times of transmission is three (Yes), it is determined whether or not 15 seconds have elapsed thereafter (step 211). When 15 seconds have not elapsed (NO), the flow proceeds to step 209. When 15 seconds have elapsed (Yes), it outputs to the line conversion relay 23e, opens the contact 23g, closes the contact 23h, connects the telephone line L of the telephone and the main telephone T, The circuit 23f is opened (step 212).

Here, it is determined whether or not (second) automatic dialing has been performed (step 213). When no (second) automatic dialing is performed again (NO), it is determined whether 5 minutes have elapsed (step 214). When 5 minutes have passed (NO), step 214 is repeated. When 5 minutes have passed (Yes), the step 201 or less is repeated again. When the (second) automatic dialing is performed again (Yes), it is determined whether or not the second (third) automatic dialing has been performed (step 215). When no (third) automatic dialing is performed (NO), it is determined whether 5 minutes have elapsed (step 216). When 5 minutes have not passed (NO), step 216 is repeated. When 5 minutes have passed (Yes), step 201 or less is repeated again.

The operation is terminated when the (third) automatic dial is performed (Yes).

In step 207, the PB signal is detected to determine whether or not the data retransmission request (#) code is received from the management center 3 after transmitting the transmission data by the transmission code to the management center 3; It is determined whether the circuit 23j has detected the # code (step 217). When the PB signal detection circuit 23j detects the # sign, that is, when the PB signal detection circuit 23j inverts from the "H" level 8V to the "L" level OV (Yes), the step ( Proceed to 208). As described above, the PB signal detection circuit 23j is inverted from the "H" level 8V to the "L" level OV, so that the # sign detection circuit 46 of the setter 4 becomes a light emitting diode ( Since the light 45 is inverted from the "L" level OV to the "H" level 5V by the supply voltage of the lithium battery 44, the display lamp 43 lights up. Therefore, when the terminal device 2 is installed, it can be confirmed that the terminal device 2 can receive the # code from the management center 3.

When the PB signal detection circuit 23j does not detect the # sign (NO), it is then judged whether or not three seconds have elapsed (step 218). When 3 seconds have not elapsed (NO), step 217 is repeated. When 3 seconds have elapsed (Yes), it outputs to the line conversion relay 23e, opens the contact 23g, closes the contact 23h, and connects the public line L of the telephone to the main telephone T. The DC circuit 23f is opened (step 219). The operation then ends.

The setter 4 inputs initial data and then removes it from the terminal device 2. After the initial data input, the terminal device 2 immediately monitors the gas leakage by the normal gas leakage sensor S1 and automatically reads the gas.

That is, in the present embodiment, when the transmission code (for example, telephone number or code number of the management center) is transmitted from the terminal device 2 to the management center 3 at the time of installation of the terminal device 2, Since the data transmission instruction (#) signal, which is a reception code from the management center 3, can be detected by the setter side as the originating signal, the terminal device 2 and the management center 3 reliably establish initial data. It is possible to confirm whether or not communication status is possible immediately after inputting a message. Therefore, on the terminal device 2 side, gas leakage, transmission control of meter reading information, data sending instruction (#) code, and feeding request (#) code are automatically performed. Control can be carried out, and the control center 3 side can also automatically control transmission instruction (#) and retransmission request (#), gas leakage and meter reading information reception control. When sending data even if there are no people at the center In this case, since the data transmission instruction (#) code or the data retransmission request (#) code is transmitted from the management center to the terminal device 2, the mutual communication between the terminal device 2 and the management center 3 is possible. do.

In the present embodiment, a lamp is used as a detection device for detecting whether the management center and the terminal device can communicate with each other when the terminal device is installed, but an audio display device such as a buzzer may be used.

터와 단말장치와의 교신을 행하여도 좋다.In the present embodiment, the communication between the management center and the terminal device is performed over a public line of a telephone, but is managed by a radio or the like using another communication line or a satellite.
