The first interface 52 is connected to the equipment 2
And the first control unit 51, the equipment 2
The status signal from the various contacts of the various sensors attached to the sensor and data such as character string data, image data, and audio data from the data transmission device are converted into digital data that can be processed by the first control unit 51. This is an element having a function of transmitting to the first control unit 51 and transmitting a control signal from the first control unit 51 to the equipment 2.

The first memory 53 is an element for storing data from the first interface 52, a telephone number of the second communication terminal 6, a communication program necessary for communication, and the like. Here, the communication program is a program for causing the first control unit 51 to execute various processes required for communication, and is a table (a table) necessary for determining various data input to the first interface 52. FIG. 4). When this remote management system is used as a remote management system for a vending machine, the table in FIG. 5 may be used instead of the table in FIG. Also,
These tables are merely examples for explanation, and it is needless to say that the number of calls and the type of data corresponding to each of the numbers of calls can be changed as needed.

The first communication unit 54 makes a call to the second communication terminal 6 under the control of the first control unit 51,
This is an element for transmitting data from the first interface 52 to the second communication terminal 6. In addition, this first
The communication unit 54 incorporates a modem for converting data from the first control unit 51 into data that can be communicated through the telephone line network 4 and a wireless communication module such as a TA, PHS module, or a mobile phone module.

In this way, by using wireless terminals for each communication terminal, it is possible to significantly reduce the installation cost when installing communication terminals in equipment and management equipment compared to the case of using a conventional wired public telephone line. And,
Communication terminals can be easily installed in places where it is difficult to lay a wired public telephone line or in equipment installed in a mobile body such as an automobile. Note that these communication terminals are not necessarily wireless communication terminals, and may be terminals using a wired public telephone line.

Hereinafter, the operation of the remote management system 1 according to the present embodiment will be described with reference to the block diagram of FIG. 1 and the flowcharts of FIGS.

First, the operation of the first communication terminal 5 when data is input from the equipment 2 will be described with reference to FIGS. 1, 2 and 4.

From the equipment 2 to the first interface 52
When the input of data into the first memory 53 is confirmed in step 701, the first control unit 51 executes the communication program stored in the first memory 53 in step 702 to determine the type of data and save the data. Necessary data is stored in the first memory 53.

At this time, the data input from the equipment 2 to the first interface 52 include the failure sensor, change sensor,
It includes status signals emitted from various sensors such as a recording paper out sensor, a safe full sensor, and the like, and data such as character string data, image data, and audio data transmitted from the data transmission device.

In step 702, the first control unit 51
If it is determined that the input data is data that can be communicated only by a call signal, that is, data such as status signals from various sensors or standard data, the data is stored in the first memory 53 in step 703. Referring to the table in the communication program (see FIG. 4),
The number of call signals is set according to the type of data.

In step 704, the first communication unit 54 makes a call to the second communication terminal 6 based on the control of the first control unit 51 by the number of call signals set in step 703. At this time, the telephone number of the second communication terminal 6 stored in the first memory 53 is referred to to make a call. At this time, the telephone number of the first communication terminal 5 using the outgoing telephone number notification service is also transmitted.

After the call in step 704 is completed, the first
The communication terminal 5 confirms whether or not a reception confirmation call has been received from the second communication terminal 6 in step 705. The reception confirmation call from the second communication terminal 6 will be described later in detail.

When the reception of the acknowledgment call is confirmed in step 705, the first control unit 51 ends the communication processing. On the other hand, if the reception of the call is not confirmed in step 705, the first control unit 51 returns to step 704 and makes a call to the second communication terminal 6 again.

In step 702, the first control unit 51
If it is determined that the input data is data that cannot be communicated only by the calling signal, that is, data such as character string data, image data, and voice data from the data transmission device, the process proceeds to step 706. , The first
Referring to the table (see FIG. 4) in the communication program recorded in the memory 53, the number of call signals is set to five.

In step 707, the first communication unit 54 makes five calls to the second communication terminal 6 under the control of the first control unit 51 with the call signal set in step 706. . In the present embodiment, the second communication terminal 6
Is set so that the line is put into a talk state when five calls from the first communication terminal 5 are received.

When the connection of the line with the second communication terminal 6 is confirmed in step 708, the first communication unit 54 stores the data in the first memory 53 in step 709 based on the control of the first control unit 51. The transmitted data such as character string data, image data, and audio data from the data transmission device is transmitted to the second communication terminal 6. Then, when the transmission ends, the line is disconnected, and the communication processing ends. On the other hand, step 708
If the connection of the line with the second communication terminal 6 is not confirmed in step (1), the first control unit 51 returns to step 707 and makes a call to the second communication terminal 6 again. Step 707
If the connection of the line is not confirmed even after performing the predetermined number of times, it is preferable to end the processing.

Next, the operation of the second communication terminal 6 when receiving a call from the first communication terminal 5 will be described with reference to FIGS. 1, 3 and 4.

When the call from the first communication terminal 5 to the second communication unit is confirmed in step 801, the second control unit
The communication program stored in the memory 63 is executed, and the number of call signals is counted in step 802. here,
The determination of the first communication terminal 5 is performed by referring to the telephone number notified by the calling telephone number notification service and the telephone number of the first communication terminal 5 registered in the second memory 63.

If the number of call signals measured in step 802 is less than 5, the second control unit 6
1 refers to a table (see FIG. 4) in the communication program and determines the type of data in step 804. In step 805, various processes such as transmission of data to the management device 3 are performed in accordance with the type of data determined in step 804.

After the various processes in step 805 are completed, the second control unit 61 makes a reception confirmation call by a predetermined number of call signals to the first communication terminal 5 in step 806. The communication processing ends. Here, the reception confirmation call is a call for notifying the first communication terminal 5 that the call from the first communication terminal 5 has been received by the second communication terminal 6. In the remote management system 1 of the present embodiment, the reason why the second communication terminal 6 that has received the call from the first communication terminal 5 makes a reception confirmation call will be described later in detail. Note that step 804 described above is used.
The order of steps 806 to 806 can be changed as needed.

When the number of call signals measured in step 802 reaches five, the second control section 61 proceeds to step 807 and connects the line. Then, in step 808, data is received from the second communication unit 64. The data received in step 808 is transmitted to the management device 3 after being temporarily stored in the second memory 63 or is transmitted to the management device 3 via the second interface 62 as it is. Has become.

When the data reception is completed in step 808, the second communication terminal 6 disconnects the line in step 809, and transfers the data stored in the second memory 63 to the management device 3 in step 810. After the transmission, the communication process ends.

Since the management equipment 3 controls the equipment 2, when it is necessary to transmit data from the second communication terminal 6 to the first communication terminal 5, contrary to the above operation, Data may be transmitted from the second communication terminal 6 to the first communication terminal 5 in a procedure reverse to the above operation. At that time, for example, the number of call signals is set according to the type of a standard command such as opening and closing of a parking lot gate, and a table showing the correspondence between the command and the number of call signals is set for each communication terminal. By referring to the communication program, it is possible to perform various controls only by communication of the call signal.

Hereinafter, in the remote management system 1 of the present embodiment, the reason why the second communication terminal 6 that has received the call from the first communication terminal 5 makes a reception confirmation call will be described in detail.

In the present embodiment, as described above, a wireless communication terminal using a wireless communication module such as a PHS module or a mobile phone module is used as the first communication terminal 5 and the second communication terminal 6.

[0051] Unlike a wired public telephone line, a radio communication terminal uses radio waves for communication, so that communication may not be performed accurately due to the influence of movement of equipment, radio interference, or the like.

Therefore, when the first communication terminal 5 and the second communication terminal 6 perform communication based on the number of call signals, the communication is terminated only by transmitting the call signal of the first communication terminal 5. Then, the first communication terminal 5 ends the communication without confirming that the second communication terminal 6 has received the information, and thus the communication ends even though the information is not transmitted. there is a possibility.

The reception confirmation call is a call made by the second communication terminal 6 in order to prevent such a situation due to the use of the wireless terminal. Specifically, after a lapse of a predetermined time from the reception of the call by the first communication terminal 5, the second
The communication terminal 6 makes a call to the first communication terminal 5 by a predetermined number of call signals set in advance. With this call,
The first communication terminal 5 can confirm that the second communication terminal 6 has received the call.

Further, when a wireless terminal is used, a line may be disconnected due to a failure that occurred during communication, and communication may not be performed accurately.

That is, if the line is interrupted due to radio interference during the calling from the first communication terminal 5 to the second communication terminal 6 based on the number of calls, the first communication terminal 5 The line is disconnected before the transmission of the paging signal of the number of times to be transmitted is completed, that is, at the time when the number of paging signals less than the number of times of the transmission is to be transmitted. At this time, the second communication terminal 6 receiving this paging signal determines that the received paging signal has been transmitted from the first communication terminal 5 for a small number of times, and performs various controls based on the determination. .

In order to prevent such a situation, the first
After performing communication based on the number of call signals from the communication terminal 5 to the second communication terminal 6, the second communication terminal 6 issues the same number of reception confirmation calls as the number of call signals transmitted by the first communication terminal 5. What is necessary is just to transmit to the 1st communication terminal 5.
Here, if the number of times of the call signal transmitted by the first communication terminal 5 and the number of times of the call signal transmitted from the second communication terminal 6 are different from each other, the first communication terminal 5 is again connected to the second communication terminal 6. The call may be made to.

By the way, in the above embodiment, when the first communication terminal 5 and the second communication terminal 6 perform communication in the stage of the telephone call state, the number of times of the call signal set in advance according to the type of data is increased. Although communication is performed based on the above, it is also possible to perform communication based on the length of the call time instead of the number of times of the call signal used in the above embodiment.
Here, the “ring time” refers to the time during which one terminal is transmitting a calling signal to the other terminal while the telephone line is not in a call.

More specifically, in the above embodiment, instead of the counter provided for the first communication terminal 5 and the second communication terminal 6 for measuring the number of paging signals,
A call time measuring means such as a timer for measuring the call time is provided, and the call time measuring means shown in FIG.
In the table, the number of times of calling signals set in advance according to the type of data is replaced with the length of calling time.

At that time, for example, in the above embodiment,
It is conceivable to change the unit length of the paging time corresponding to one paging signal, which is the number of paging signal units, to one second of the paging signal. The unit length of this calling time is
It can be changed as needed. Also, the unit length of the call time may be any length of time as long as each unit can determine the unit time,
For example, the time can be set to 0.1 second or less.

As described above, when the communication is performed based on the length of the call time, the communication time is significantly reduced as compared with the case where the communication is performed by the number of call signals as in the above embodiment. Is possible.

Finally, it is needless to say that the present invention is not limited to the above-described embodiment, and various changes and improvements can be made within the scope described in the claims.

In the description of the present embodiment, the invention mainly made by the present inventor is applied to a remote management system of a parking lot settlement apparatus, which is a field of use as a background. However, the present invention is not limited to the field of use of the present embodiment, but can be used for a remote management system and a general communication system using a telephone line network.

[0063]

As described above, according to the present invention,
Since the communication terminals can transmit and receive data depending on the number of call signals, a remote management system capable of minimizing communication costs is realized. Further, since the present invention uses a wireless communication terminal as a communication terminal, it is possible to reduce the installation cost when installing the communication terminal in the device, and to perform remote management regardless of the installation location of the terminal.
