Abstract

PURPOSE:To automatically set a device from a distant place by executing resetting by changing over a switch or the like according to set information transmitted from the distant place. CONSTITUTION:Assuming that communication is enabled with a terminal equipment on the reception side, in such a state, a CPU 104 always monitors a received data signal 'RD' of a MODEM. When a set command data 'SETTEI' is received during communication, the CPU 104 switches a changeover switch 105. Simultaneously with this switching, the CPU 104 transmits the response of confirmation to a terminal equipment on the called party side. Next, a standby state is set to receive the set information (numerical value code) from the terminal equipment on the called party side. Afterwards, the CPU 104 receives the transmitted set information and switches a set switch 106 or reloads set contents stored in a RAM 107 based on the set information.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for automatically setting device settings by remote control in a communication terminal device that can automatically receive calls using a modem.

(Prior Art) Setting contents of a communication terminal device include, for example, communication speed, code unit, communication mode, etc. Communication speed is the amount of data communicated per unit time.

The code unit is determined by how many bits the communication code consists of and whether the parity bits are even or odd bits. Communication modes include automatic calling and automatic receiving, manual calling and automatic receiving, and
Alternatively, it is determined whether to manually make a call or manually receive a call.

In this type of device, the following methods have been used to determine the setting contents.

The first method is to switch using an operation switch provided in the device itself.

The second method is to rewrite the contents of the storage device using input from the keyboard.

The third method is to connect R3-2 from the terminal device connected to the device.
This method rewrites the contents of a storage device using command data using a 32C interface.

In this way, settings are performed by the device itself or by a terminal device connected to its periphery.

(Problems to be Solved by the Invention) However, the above-described conventional technology has the following problems.

In other words, settings can only be made on the own device or its surroundings, so for example, if a communication terminal device is used in an unmanned system and you want to change the communication mode of that device, maintenance personnel etc. There was a problem in that it was necessary to go to the site where the system was installed and make the settings.

The present invention has been developed with the above points in mind, and in order to set the mode etc. of a device, it is necessary to go to the location where the device is installed and perform the settings by registering using a switch or keyboard. It is an object of the present invention to provide a method for automatically setting device setting contents by remote control, which eliminates the inconvenience that would otherwise occur and allows the setting contents to be changed from a remote location using a modem.

(Means for Solving the Problems) A method for automatically setting device settings by remote control according to the present invention includes a modem for communicating data, monitoring means for monitoring communication data, and settings for determining device settings. The present invention is characterized in that upon reception of specific data, the device automatically sets the content corresponding to the specific data.

(Function) In the method for automatically setting device settings by remote control of the present invention, switches and the like are changed based on setting information sent from a remote location, thereby redoing the settings. In this way, the device can be automatically configured from a remote location.

(Embodiment) FIG. 1 is a block diagram of an embodiment of an apparatus to which the method of the present invention is applied.

The illustrated device includes a 2-wire to 4-wire converter 101 and a modem 10.
2, R5-232G interface 103, and CP
Consists of U 104 etc.

The 2-wire to 4-wire converter 101 serves as a telephone line interface.

Modem 102 is a device for modulating and demodulating data to be communicated.

The R3-232C interface 103 is a well-known general-purpose interface, and is connected to a terminal device (not shown).

The CPU 104 serves as a monitoring means and a setting means, and processes data stored in the RAM+07 and performs various controls.

That is, the CPU 104 constitutes a monitoring means for monitoring communication data, and constantly monitors signals received via the modem 102.

Further, the CPU 104 constitutes a setting unit that determines the settings of the device. In other words, the setting switch 106 can be switched and the setting contents can be written to the RAM 107.

The changeover switch 105 selects the route of the transmitted data signal from the modem 102 to the R3-232C interface z-4103 or
This is a switch for switching to one of the CPUs 104. This switching is performed by CPU 104.

The setting switch 106 determines the contents of device settings.

The RAM 107 is a readable and writable memory, and stores device settings and the like.

FIG. 2 is an explanatory diagram of the information setting procedure.

When a specific command is received during communication, a confirmation response is first sent out. The specific command is an appropriate code, such as "5ETTEI", and the confirmation response is, for example, "OK". When the receiving side confirms this response, it then sends the device settings. .The device settings are expressed, for example, by the numerical code "]2)..." as shown in the figure.In other words, the first numerical code is "l", which means that the communication speed is 1200 bps. "O" indicates that communication is to be performed at a communication speed of 300 bps.Hereinafter, the next numerical code will indicate the code unit, the next numerical code will indicate the communication mode, etc. and send all device settings.

FIG. 3 is an overall configuration diagram of the system according to the present invention.

The illustrated system includes a terminal device 301 and a setting target device 30.
Consists of 2.

Terminal device 301 is connected to a telephone line via modem 303.

The setting target device 302 is a device that includes a built-in modem that is connected to a telephone line. Note that the modem does not need to be built-in, and may be externally attached. Further, in the illustrated example, a terminal device 304 is connected to the setting target device 302. Even when this terminal device 304 is not provided, it is possible to realize the present invention.

Next, the operation of the above system will be explained.

First, assume that the device is in a communication state with an automatic call receiving function. That is, in such a communication state, the 2-wire to 4-wire converter 101 is connected to the telephone line, and the modem 102 and RS
A route is created that passes through the -232C interface 103 and connects to the terminal device. This makes it possible to communicate with the terminal device on the receiving side.

In this state, the CPU 104 constantly monitors the received data signal "RD" of the modem. Therefore, CPU
104 indicates setting command data “5ETTEI” during communication.
", the changeover switch 105 is switched. At the same time, the CPU 104 sends a confirmation response "OK" to the terminal device of the other party. Then, the setting information ( Next, the CPU 104 receives the sent setting information, switches the setting switch 106 based on the setting information, or changes the setting contents stored in the RAM 107. This allows the device to operate according to the configuration information.

Therefore, the terminal device 301, which is the side that performs settings remotely,
Once the configuration is completed, it is brought into a communication state with the setting target machine 302 and a setting command "5ETTEr" is sent. When the setting becomes possible, a confirmation response "OK" is returned. Therefore, by confirming the response and sending the setting information to be newly set to the setting target device 302, the device thereafter operates according to the sent setting contents.

(Effects of the Invention) As explained above, according to the method for automatically setting device settings by remote control of the present invention, communication motes etc. are automatically set to the target device from a remote location using communication via a modem. Since the settings can be made, there is an effect that when maintaining the device, there is no need to go to the site to make the settings when there is a change in the settings.
