First, the operation procedure of the entire call control device 20 will be described with reference to FIG. Now, the external device 10 is connected to the I / F connector 214 of the call control device main body,
It is assumed that the subscriber telephone line is connected to the modular jack 215 and the power switch 216 is turned on.

In such a state, the call controller 20

Determine whether it is in an operating state that allows incoming calls. In addition,
The selection switch 205 switches between the RUN execution mode and the parameter setting mode.

If it is determined in step S1 that the mode is not the RUN execution mode, the process proceeds to step S2 and the CPU
It is determined whether 201 is the parameter setting mode. here,
When it is determined that the parameter setting mode is set, the process proceeds to step S3, and when a negative determination is made, the process returns to step S1.

In step S3, the switches 205, 2
The current time (TIM
M), self-identification number (ID), pager phone number (TEL), trigger mode (MOD) at transmission start
Various parameters such as E), the number of ring sounds at the time of incoming call (RING), and the selection of the target pager company (BELL) are set. Details of this parameter setting will be described later.

In step S4, the I / F connector 241

It is read into the CPU 201 through the input interface 204. Then, in the next step S5, a process for checking the transmission start condition is performed. The details of this check processing will be described later.

In the next step S6, transmission activation is determined based on the check result. Here, if it is determined that the transmission is not activated, the process returns to step S1, and if it is determined that the transmission is activated, the process proceeds to step S7.

In step S7, the CPU 201 gives an activation command to the transmission control unit 212 to activate the transmission control unit 212, reads the dial number of the pager 50 stored in the RAM 203, and automatically uses this dial number. By making a call, a call path between the call control device 20 and the base station 40 via the public network 30 is established. After that, the self-identification number and the state information of the external device 10 are encoded and transmitted to the base station 40 (step S
8).

On the other hand, the base station 40 checks whether or not there is a subscriber of the received dial number. If the subscriber is a subscriber, the coding device built in the base station 40 is activated to activate the selective call code and the external device. The self-identification number of 10 and the status information are transmitted from the transmitter of the base station 40.

The pager 50 receives the selective call signal transmitted from the base station 40, and when the calling number coincides with the number of the pager 50 itself, ring the sounding means incorporated in the pager 50. To generate a ringing sound to allow the pager wearer to use the external device 1
Notify that there was a call due to a 0 state change. At the same time, the self-identification number of the external device 10 and the current external device 10 are displayed on the display portion 50a of the pager 50.
The state of is displayed by numbers or letters.

Next, the parameter setting processing operation will be described with reference to FIG. In the state where the CPU 201 is set in the parameter setting mode, the selection switch 205 is pushed, and a switch-on signal generated each time the push operation is performed is fetched into the CPU 201, whereby the variable C is incrementally processed to select a parameter, which is selected. The displayed parameters are displayed on the LCD display unit 209.

In the next step S12, it is determined whether the incremented variable C is C = 1. Here, when it is determined that C = 1, the process proceeds to the setting process of the current time (TIME) shown in step S13, and when it is determined that C = 1 is not satisfied, the process proceeds to step S14. In the TIME setting process of step S13, the counting content of the counting circuit 211 is changed to C
Captured in PU201, L via display control circuit 210
By outputting to the CD display unit 209, the timing content can be
It is displayed on the D display unit 209.

Here, when the timekeeping content displayed on the LCD display unit 209 is to be corrected, an on / off signal obtained by push-on / push-off operation of the number input switch 206 is fetched into the CPU 201. Thereby, each numerical value of the hour / minute / second of the clock circuit 211 is changed and each numerical value of the hour / minute / second is corrected to the current accurate time. In step S14, it is determined whether the variable C is C = 2. If it is determined that C = 2, the process proceeds to the ID setting process of step S15 for setting the identification number ID of the calling device itself.

In the ID setting process shown in step S15,
An on / off signal obtained by push-on / push-off operation of the number input switch 206 is sent to the CPU 2
01 is set and the identification number of the calling device itself is set. The identification number at this time is displayed on the LCD display unit 209.

Therefore, the predetermined identification number is LCD
If it is displayed on the display unit 209, the setting switch 207
Is pushed to confirm the identification number, and the identification number is stored in the RAM 203.

When it is determined in step S14 that S = 2 is not satisfied, the process proceeds to step S16, where the variable C is C =
3 determines. Here, if it is determined that C = 3, the process proceeds to the TEL setting process of setting the telephone number of the pager 50 that is the calling party shown in step S17.

In the TEL setting process shown in step S17, the on / off signal is sent to the CPU by pushing the number input switch 206 on / off.
Pager 5 who is the person to call in 201
Set a phone number of 0. The phone number at this time is LCD
It is displayed on the display unit 209. Therefore, when a predetermined telephone number is displayed on the LCD display unit 209, the setting switch 207 is pushed to fix the telephone number, and the telephone number is stored in the RAM 203.

If it is determined in step S16 that C = 3 is not satisfied, the process proceeds to step S18, where the variable C is C =
Determine if 4. If it is determined that C = 4, the MODE for starting transmission shown in step S19.
Move to setting processing.

In the MODE setting process shown in step S19, an activation command for activating transmission of the calling device is set. The call activation command for the call device is 30/60/1
A TIME command that activates transmission every 20 minutes, an I / O command that activates transmission when the external device 10 changes state such as a failure, and a trigger that activates transmission when the external device 10 is on / off. There is a directive.

These start commands are issued by the numeral input switch 2
06 is selected by a push operation, and the selected start command is determined by a push operation of the setting switch 207 and is stored in the RAM 203.
Therefore, the call device is activated for transmission by the determined activation command. Also, 30 of the TIME command
The time such as / 60/120 is set by the numeral input switch 206 and the setting switch 207.

When it is determined in step S18 that C = 4 is not satisfied, the process proceeds to step S20, where the variable C is C =
Determine whether it is 5. Here, when it is determined that C = 5,
The process proceeds to the RING setting process shown in step S21.

The RING setting process shown in step S21 is for setting the number of ring sounds when an incoming call is made when the pager wearer calls the calling device through the outside line telephone 60. The number of ring sounds is set by pushing the number input switch 206 and the setting switch 207 and stored in the RAM 203.

When it is determined in step S20 that C = 5 is not satisfied, the process proceeds to the switch 22 and the variable C is set to C = 6.
To determine. Here, when it is determined that C = 6, the process proceeds to the BELL setting process shown in step S23.

In the BELL setting process, a base station corresponding to a target pager trader such as NTT or Tokyo Telemessage is selected. As the selection number, the number of the base station 40 is pushed to push the numeral input switch 205. The selection number thus set is stored in the RAM 203 along with the telephone number for pager call by pushing the setting switch 207.

If it is determined in step S22 that C = 6 is not satisfied, the flow advances to step S24 to set the variable C to C =
Determine if 7. Here, when it is determined that C = 7, the process proceeds to step S25, and the calling device is set to the RUN execution mode.

Next, the operation of checking the transmission start condition after the calling device is set to the RUN execution mode will be described with reference to FIG.
Will be described with reference to. When the transmission activation check program shown in FIG. 5 starts, first, in step S31, it is determined whether there is an incoming call from the pager carrier side. If it is determined that there is an incoming call, the process returns to step S6 in FIG. When it is determined that there is no incoming call, the process proceeds to step S32, and it is determined whether the transmission activation mode of the calling device is the time monitoring mode according to the TIME command.

If it is determined in step S32 that the time monitoring mode is set, the process proceeds to step S33, and if a negative determination is made, the process proceeds to step S34. In step S33, it is determined whether or not the set time has elapsed, and if the time is up, the process proceeds to the process of activating the call device to transmit by the TIME command. Also, step S3
In step 4, it is determined whether the call activation mode of the call device is the I / O monitoring mode according to the I / O command. If it is in the I / O monitoring mode, it is determined in step S35 whether the state of the external device 10 has changed. Here, if there is a change, the process shifts to a process of starting transmission of the calling device by an I / O command. If there is no change, the transmission is not started and the process returns to step S6 in FIG.

If it is determined in step S34 that the mode is not the 1 / O monitoring mode, step S36
Then, it is determined whether the transmission start mode of the calling device is the trigger mode by the trigger command. Here, when it is the trigger mode, the process proceeds to step S37, and it is determined whether there is a trigger. If there is a trigger, the process shifts to the process of activating the call device by sending a trigger command. If the trigger mode is not set and there is no trigger command, the transmission is not started and the process returns to step S6 in FIG.

In this way, an incoming call to the calling device, a TI
By checking the ME command, the I / O command and the trigger command, when one of these is recognized, the call device is activated to be sent and the pager is called.

Next, the transmission processing operation of the calling device will be described with reference to the flowchart shown in FIG. When the transmission processing program shown in FIG. 6 starts, first,
In step S41, it is determined whether the call device is ready for transmission. Here, in the case of transmission OK, step S
In step 42, the number of transmission processes (LOOP) is initialized.
If it is determined that the preparation for transmission is not yet completed, the process proceeds to step S57, and the transmission flag is reset.

After the processing of LOOP = 0 is performed in step S42, the process proceeds to step S43, and it is determined whether the number of transmission processings of the calling device is LOOP = 5. If it is determined that LOOP = 5, step S
In step 44, the error display process of the transmission loop is executed, and the process proceeds to step S46. When it is determined that LOOP = 5 is not satisfied, the process proceeds to step S45, and it is determined whether the transmission processing circuit is LOOP = 10.

When it is determined that LOOP = 10, the process proceeds to step S57, and the transmission flag is reset.
If it is determined that LOOP is not 10, it is determined in step S46 whether the line of the calling device is in use. If it is in use, the process proceeds to step S47, and after waiting for a predetermined time, in the next step S48,
The number of transmission processes is set to LOOP = LOOP + 1, and the process returns to step S43.

If it is determined in step S46 that the line is not in use, the flow advances to step S49 to put the calling device in the off-hook state. Then, in the next step S50, it is determined whether or not there is a tone signal from the exchange of the public network 30. When the CPU 201 confirms the tone signal, it performs key-in processing on the telephone number for calling based on the telephone number for calling stored in advance in the RAM 203 (step S51).

Thereafter, in step S52, it is determined whether a call is in progress. If no call is in progress, the next step S53.
It is determined whether or not silence is detected. When the silence is detected, the parameter such as the identification number of the calling device is keyed in in the next step S54. Then, in step S55, it is determined whether the transmission process has been normally completed. Then, when it is determined that the transmission process is normally performed, the on-hook process is performed in the next step S56, and the process proceeds to the next step S57.

If it is determined in step S50 that there is no tone signal, the flow advances to step S58 to turn on.
After performing the hook process, the process of LOOP = LOOP + 1 is executed (step S59), and the waiting process (step S60) is further executed, and then the process returns to step S43. If it is determined in step S52 that a call is in progress, the processes of steps S58-60 are executed. Further, if no silence is detected in step S53 and if normal termination is not performed in step S55, the processes of steps S58 to S60 are performed similarly to the above.

Next, the incoming operation of the calling device will be described with reference to the drawings. In this case, the pager carrier starts the incoming call processing program of FIG. 7 by dialing the telephone number corresponding to the calling device from the nearest outside line telephone 60.

First, at step S71, it is judged at 71 whether or not there is a ring sound. When the ring tone is present, when it is recognized that the ring tone has been received a preset number of times or more, the off-hook process shown in step S71 is performed, and the line with the outside line telephone 60 is connected.

After that, in the outside line telephone 60, the identification number of the calling device is input by operating the push button of the outside line telephone 60 after the telephone number of the calling device. Accordingly, in the call device, the tone signal generated by the push button operation is received by the incoming call control unit 213, and the received signal is output to the CPU 201 (step S7).
3).

When the pager wearer goes on-hook, the disconnection signal is transmitted to the calling device through the public network 30, and the line is cut off by the on-hook operation of the calling device (step S74).

After the on-hook processing, it is judged whether the incoming call processing of the calling device has been normally completed (step S7).
5). Here, if it is determined that the incoming call process has been normally completed, the process proceeds to step S76, and it is determined whether the tone signal subjected to the reception process is the identification number ID of the calling device itself.
If it is the own identification number, the process proceeds to step S77,
The call device is operated to transmit, and the current state of the external device 10 is transmitted to the pager 50.

If the process is not normally terminated in step S75, the process proceeds to step S78 to perform an error display process, set a system error code in the next step S79, and shift to transmission process control. By enabling such incoming call processing, the current state of the external device can be arbitrarily monitored from the pager 50 side.

In the pager call apparatus of this embodiment as described above, the call control apparatus 20 is generally activated by transmitting a signal generated by a change in the state of the external apparatus 10 or a signal generated at a predetermined time period. By connecting to the public line and calling the corresponding pager by automatically dialing a preset telephone number, the state information of the external device 10 is coded and transmitted. The status of the device can be directly reported to the pager wearer, and unmanned management of the external device becomes possible.

Further, since the call control device 20 is configured to be activated by an incoming call from the pager carrier, it is possible to arbitrarily know the state of the external device at any time according to the request from the pager carrier. You can Furthermore, by providing a call control device, it is possible to easily realize remote monitoring of an external device by using an existing base station and pager.

The present invention is not limited to the configuration shown in the above embodiment, and various modifications can be made without departing from the scope of the claims.
