Has

However, there are some things to consider in the operation step of FIG.

First of all, the operation program in the server may include an operation program for a device provider.

It is divided into operation programs for device users, but in reality,

It is preferable to integrate management with an operation program, and also RS-232 device 100

The display data for the display device is based on the type and function of each RS-232 device.

The display data format varies depending on the type and performance of the display device used.

The display data format is different and you want to transfer the data to the RS-232 device.

The provider program of the device provider, which is the data producer,

The user program is responsible for controlling the display of the RS-232 device.

It must match the format used and produces the display data of the RS-232 device.

The program simulates the data on the computer before transferring the data to the device.

It is preferred to have

In addition, there are some problems in the operation according to FIG. 3. Especially if the device provider

When data is sent to a device provided by the user, the data is immediately

There is no guarantee that it will be sent to the device and the device user

There is a problem according to the transmission method after accumulating in the server to be transmitted only when there is.

In particular, if the device provider requests to change the authentication key used only by the device provider,

If the device user is using the device, the server performs the request and

The device provider program can be notified of the results, but in some cases the device

It may happen that the provider is unable to access the server.

In order to solve the above problem, there are some considerations in the overall system.

Is needed.

The first provider program must change the authorization key before

Keep the authentication key, and if the server authentication fails with the new authentication key,

Authenticate with the stored authentication key. In addition, the previous authentication key change request

If not successful, request to change new authentication key is prohibited.

The operating program can determine the result of processing the authentication key change request of the provider program.

Inform the provider program at the time.

Second, it is not used well for general computers using dynamic IP such as DHCP.

However, the user program in the user operation (S150) step is the first user

When you connect to the server after starting the program, enter the IP of your computer to the server.

Send a message, notify the server of the disconnection in the server disconnection phase, and

Pre-manufacturing steps, so that the device provider can connect directly to the server separately

Define the port number in (S100), create and wait for the server type socket

If there is a connection to the socket, a device unique number and authentication key are received.

If the device unique number matches, the authentication key sent from the RS-232 device and the received

After authenticating that the authentication key matches, if authentication succeeds, the device provider program

Receives the work request and transmits it to the RS-232 device.

In a way to notify the program, the server operating program is the user program

Register the IP of the user computer 200 transmitted at the time of connection, and at the time of disconnection.

Device user, if requested by the device provider program by deleting the IP

It provides a connection between the computer 200 and providing an IP.

The provider program also sends a server to the server to send data to the provided device.

The device user receives access to the computer and the IP, and the user

Directly access the user program on the computer and, if the connection is successful, authenticate

Authentication by sending the device unique number and authentication key to the user program.

Receive and perform the necessary tasks.

The server does not write the authentication key of the third device provider to the RS-232 device.

Used for device provider authentication, the device provider program

After authenticating to the server with a unique number and authentication key,

Register with the server, and the device user program connects to the server and registers with the server.

A communication method for transferring data to a device.

Figure 4 is an embodiment of the present invention Hangul 8 characters two lines display LCD and red (R),

This is an example of the command system used and data processing in the RS-232 device.

FIG. 5 is a flowchart of a user program of the RS-232 device user side computer; FIG.

A flowchart detailing the operation of the user operation (S150), with reference to FIG.

Explain.

The user computer startup (S200) of FIG. 5 is used for booting a computer or operating a user.

Means the first start of the user program, and the device connection (S210) is RS-232

This step is to determine whether the device is connected to the user's computer and operating normally.

The user program opens the communication port that the device is connected to when installing the user program.

The device is assigned to the RS-232 device after being authorized to use the communication port.

Request to send a unique number to receive the device unique number normally from the device

It is the step of determining whether it is.

If the device connection (S210) is registered in the computer from the RS-232 device in the step

If you do not receive the same device unique number, power off the RS-232 device.

Communication status, the connection between the RS-232 device and the computer is disconnected, or

Caused by the failure of the device, a certain time elapsed set in the user program (S220)

After requesting the RS-232 device to send the device unique number again, check the connection.

Depending on the program, the program can be terminated immediately.

If the device connection (S210) determination step from the RS-232 device normally

When the device unique number is received, the current

The operating status of the fountain and the indication status of the LEDs, etc.

In order to receive the data registered in the server,

Receiving device information for receiving the authentication key from the RS-232 device,

The authentication key received from the RS-232 device is used to authenticate the server.

A step (S230) of receiving server connection is performed.

The server connection is also based on the authentication and communication scheme, the device user computer

The server's IP address and allow the device provider to directly access your computer.

This includes creating a socket of the form.

User computer and RS-232 for receiving the authentication key from an RS-232 device

The communication between the devices will be described in detail with reference to FIG. 4, as shown in E1 of FIG. 4.

Your computer is responsible for the main command 81H and subcommand 02H, data length depending on the command format.

Send 00H, 08H to RS-232 device. The main command 81H has an IN direction,

The producer of the information is the user's computer, the destination is the memory, the RS-232 device

Means to transfer the contents of the memory to the computer.

Means user program, sub-command 02H means authentication key of memory,

The data length 00H and 08H mean that the length of the authentication key is 8 BYTE.

RS-232 device receiving the command sends the authentication key 'KIPO0047' 8 BYTE to the memory.

Read it and transfer it to your computer. The user program that receives the authentication key

The authentication key is not exposed to the device user, only for authentication of the server.

Since it is the data for the purpose, it is sent to the server without being displayed on the screen.

Also, if more security is required, it is recommended to encrypt the authentication key.

Do.

In addition, as described above, if a user receives a device identification number and an authentication key separately

The program is complex and inefficient, so the device unique number and authentication key

Can be received. In the above case, if the device unique number is 8 BYTE of '06040848'

The primary command is 81H and the minor command is 03H for both device unique number and authentication key.

The data length is 8 BYTE, respectively, 00H and 10H which are 16 BYTE in total.

When the RS-232 device receives the command, the RS-232 device receives the device unique number and authentication key.

Read and combine 16 BYTE '06040848KIPO0047' from your memory

To transmit.

The right to change the authorization key depends on the authorization policy, depending on the intended use of the product and how it is used.

Depending on the device provider or the device user may be possible.

The exact meaning of the producer of Figure 4 is the case of transmitting data to the RS-232 device

The distinction between the device user computer that produced the data and the device provider computer.

When receiving data from an RS-232 device, it is physically requested as an information requester.

Directly attached device A device that is a user's computer and a remote computer that contains a server.

The division of the provider computer.

If the device user also has permission to change the authentication key, the device user

Change the authentication key arbitrarily so that the device provider can send data to the device

In order to prevent the case that cannot be transmitted, the producer division of the command format of FIG.

In the case of a provider, it is preferable to use the following.

In this case, the RS-232 device uses an authentication key that the device provider knew last.

If the device provider requests to change the authentication key to enable authentication, the device provider

In order to change to a new authentication key, the authentication key finally used for authentication

Keep it in a separate memory and store the newly changed authentication key with the device user.

Writes to the current authentication key memory used, allowing the device user to

Even if the key is changed, the device provider can use the separately stored authentication key

Enable authentication, and also allow the device provider to know the current authentication key

do.

Therefore, the device provider's authentication key change command format replaces the existing authentication key.

In order to change to the authentication key, the existing authentication key for authentication

Since a new authentication key is required, the data length is twice the length of the authentication key.

Also, if there is a request to send an authentication key from the device provider, the command format 4 BYTE

Receive the existing authentication key and the existing authentication key as shown above

If it matches with the authentication key, the current authentication key is transmitted.

If the provider provider's authentication fails, the server's provider manager

Send the authentication key sent by the device provider to the device user program;

The user program asks the RS-232 device for an authentication key whose requester is the provider,

RS-232 device with the existing authentication key of the device provider received from the server

Transmit the received authentication key to the server.

It is desirable to perform authentication once again using the received authentication key.

In addition, the device user program can be used to configure the request between the server and the RS-232 device.

It relays the processing result and displays the final authentication key of the RS-232 device on the screen.

The function is desirable.

Determination of data existence (S240) of FIG. 5 indicates that the device provider is connected to the currently connected RS-232 device.

The data to be transmitted is registered with the server or received in the server type socket.

It is the step of determining whether the data is present. If the device provider wants to send

If there is data, the data receiving step S250 is performed. The data receiving step

The device provider may not change the display function or the authentication key of the device

In order to register the data to be transmitted to the device with the device unique number as a key,

The contents of the user's device on the user's computer

The data is sent automatically without any manipulation. Also, the server type described above

If you use sockets, the user program must

Receiving data directly from the user's computer,

This includes authenticating. If the received data is normal data

The user program transmits the received data to the RS-232 device (S260).

Perform the steps.

More specifically, the step of transmitting to the RS-232 device (S260), E3 of FIG.

The provider sends a birthday melody to the RS-232 device, which causes the RS-232 device to

For playing melodies at timed intervals, the user program

Main command 44H, which is an output command for hearing devices of RS-232 devices from a provider;

Hearing devices have no definition for subcommands, so 00H and the data being sent

When the length 280H is sent to the RS-232 device, the RS-232 device receives the command.

After that, the next 640 BYTE is received and stored in memory.

The device of 640 BYTE for the speaker control is the data producer

RS-232 to directly control speaker devices using provider programs and the data

You must match the format used by the device's firmware.

If the device provider says 'Happy Birthday' on the second line of the LCD on the RS-232 device,

If you want to display, the main command is 42H, the sub command is 0AH (LCD LINE 1) and the data

The length is 10H, followed by the 'Happy Birthday' character data.

If the data present (S240) determination step from the device provider to the RS-232 device

Data registered with the server for transmission, or device user by the device provider

If no data is sent directly to the program, the device user

To change the display method by controlling or transmitting data to the display device.

After the user transmission (S270) step to determine whether you want to transfer the data

If the device user wants to transfer, it is in the promised format

Produces data (S280), displays it virtually on a computer, and sends it to an RS-232 device

And transmitting to the RS-232 device (S260) is the same as described above,

Since data producer is user, producer division bit shall be 0.

E2 of FIG. 4 shows that the device user has the LED of the music fountain directly from the user's computer 200.

As an example of controlling the main command 02H means that the user outputs to the visual device.

Subcommand 05H turns LED red and blue ON and green OFF and data length 0

Indicates that no data is required. Also as above RS-232 device

RS-232 device if a command to directly control the

It is preferable to ignore the command or change the processing method.

Also, as shown in E2 of FIG. 4, in order to allow the user of the device to change the water height of the fountain.

In order to directly control the speed of the motor, it is not specified in the command format of FIG.

Negative command of drive device Lowest bit Bit of the upper 7 bit except motor ON / OFF

When defined by the speed, it is possible to control the water height by controlling the rotational speed of the motor.

The user transmits data to the RS-232 device in the user transmission (S270) determination step

If you do not want to exit, decide whether to exit the device user program.

In operation S290, if the device user terminates the user program,

If desired, the user program will contact the server before terminating the user program.

Release (S300). When the device user program is disconnected from the server, the device

The provider has no means to send data to the RS-232 device it provided,

Just register the data you want to transfer to the server to the server,

When a program connects to the server, it is sent

However, if the purpose of the RS-232 device is solely a promotional device for advertising,

The RS-232 device may not receive commands from the computer it is connected to for some time.

If the RS-232 device stops operating, the user program

If the server does not request the data transmission within the predetermined time,

In order to prevent the operation of the RS-232 device,

By adding the ability to send commands to RS-232 devices, device users

Connect the RS-232 device and your computer normally, and

In order for the RS-232 device to function normally,

If the device provider wants to send data to the device they provided

It is desirable to induce quick transfer to RS-232 devices.
