Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bar code scanner,

The present invention relates to a communication mode switching recognition device for a barcode scanner, and more particularly, to a communication mode switching recognition device for a barcode scanner, more specifically, a product barcode dock for product production history management. And more particularly, to a communication mode switching recognition device for a bar code scanner.

Manufacture Excution Systems (MES) is a system that improves efficiency throughout production and manages the history of products that are produced in real time. MES can include a number of local systems to ensure the efficiency of product production processes such as process progress information monitoring and control, facility control, quality information tracking, performance information aggregation, warehouse operation management, inventory management, and material input management. MES can manage the product production history by attaching the product information to the product in the form of barcode and reading the product barcode information through the barcode scanner.

As a prior art related to a communication mode switching method in a barcode scanner, Korean Patent Laid-Open No. 10-2008-00563337 discloses a barcode device that provides a wired / wireless interface. The prior art includes a barcode imager for optically recognizing and reading a barcode, a first memory for storing barcode data corresponding to a barcode recognized by the barcode imager, a connector for connecting to a host by wire, A Bluetooth module for transmitting the barcode data to the host through a Bluetooth communication method, a serial communication module for transmitting the barcode data to the host through the serial communication method, and a barcode imager, And a CPU for controlling operations of the Bluetooth module and the serial communication module and for transmitting the barcode data to the host via the USB through the connector. However, the above-described prior art only discloses a bar code device (bar code scanner) for transmitting the read bar code data by the serial communication method or the USB method.

In the MES environment, the product barcode information is read through each barcode scanner, which is divided into a USB communication mode or a serial communication mode, which is preset in the production line and is supported on the production line, so that the operator uses the barcode scanner Otherwise, there may be a problem that the product production history is omitted. For example, the product bar code information transferred in one conveyor and attached to the product operated in the A process line is transmitted to the host computer through the bar code scanner set in the USB communication mode, and the product operated in the B process line The requested product barcode information is transmitted to the host computer through the barcode scanner set in the serial communication mode. Therefore, the operator must read the product bar code information through the bar code scanner supporting the communication mode according to the product operated in the A process line or the B process line, so that the product production history is accurately transmitted to the host computer and the production history is managed in the MES server . However, if the operator reads the product bar code information of the A process line through the bar code scanner set in the serial mode or reads the product bar code information of the B process line through the bar code scanner set in the USB mode, The computer does not recognize the barcode information of the read product and the product information is not transmitted to the MES server. In addition, since the operator uses a plurality of barcode scanners to read product barcode information operated in the corresponding process, it is impossible to check whether the barcode scanner is correctly inputting product barcode information currently read by the barcode scanner. Since the barcode scanner does not have a display unit for the operator to confirm the change of the communication mode, the operator can not confirm the communication mode change of the barcode scanner through the barcode scanner.

That is, in order to read the product bar code information in order to manage the product production history in a work environment provided with a plurality of bar code scanners and set to a communication mode required by each process line, when an operator uses a wrong bar code scanner in the process line The read barcode data is processed differently according to the USB communication mode or the serial communication mode, and there is no way for the operator to check the barcode data, so that the production history of the product is omitted, and the production efficiency under such working environment is inevitably lowered.

Accordingly, when a plurality of bar code scanners classified into the conventional USB communication mode or the serial communication mode are unified into one bar code scanner and the communication mode of the bar code scanner according to the switched bar code scan is changed, it is determined that the communication mode of the bar code scanner is changed It is necessary to provide a communication mode switching recognition device of a barcode scanner which can prevent a product production history from being missed by notifying the operator of the current communication mode status information through the display unit.

For example, the production history management system 1000 includes first barcode information attached to a product 32 produced in a process A among the products transferred from the conveyor 10 through a barcode scanner 100 set in a USB communication mode The first bar code information may be transmitted to the MES server 300 through the communication mode switching recognition device 200. [ In the production history management system 1000, for example, the second bar code information attached to the product 42 produced in the B process among the products conveyed from the conveyor 10 may be a bar code scanner (for example, The second barcode information can be transmitted to the MES server 300 through the communication mode switching recognition device 200. [ In order to read the respective bar code information attached to the A process product or the B process product transferred from the conveyor through the required communication mode, the bar code scanner 100 checks the communication The first switching bar code 31 or the second switching bar code, which is a code for commanding switching to the mode, can be scanned and transmitted to the communication mode switching recognition device 200. [

The barcode scanner 100 is connected to the communication mode switching device 200 through a USB communication mode or a serial communication mode (for example, RS-232) to barcode data acquired through a scanning unit optically recognizing and reading the barcode To the communication mode switching recognition apparatus. The switching bar code is a command for changing the communication mode between the bar code scanner and the communication mode switching recognition device, and may be a predetermined bar code. The barcode scanner 100 may include a wireless communication module capable of transmitting barcode data scanned through wireless communication (for example, Bluetooth, etc.) as well as wired communication to the communication mode conversion recognition device 200. [

The communication mode switching recognition device 200 may be provided with a USB communication mode driver and a serial communication (USB-RS232) communication mode driver provided by the manufacturer of each barcode scanner in order to set a communication mode with the barcode scanner. When the communication mode switching recognition device 200 receives the switching bar code from the bar code scanner 100, the communication mode switching recognition device 200 can be connected to the bar code scanner in the communication mode according to the switching bar code. The communication mode switching recognition device 200 can be connected to a barcode scanner through a predetermined connector (USB terminal or serial port). The communication mode switching recognition device 200 may be a computer (industrial) or a notebook computer having a predetermined operating system (for example, Windows (TM)) installed therein and including an interface for a barcode scanner and wired or wireless data communication. The communication mode switching recognition apparatus 200 can transmit the product barcode data received from the barcode scanner to the MES server 300 through the set USB communication mode or the serial communication mode.

2 is a block diagram of a communication mode switching recognition apparatus according to an embodiment of the present invention.

2, the communication mode switching recognition apparatus 200 includes a barcode receiving unit 210 for receiving a barcode (product barcode or conversion barcode) data from a barcode scanner, a communication unit 210 for determining whether the received barcode data is a conversion barcode or a product barcode A communication mode setting unit 230 for setting the communication mode according to the switching barcode when the barcode data input from the barcode determining unit is a switching barcode, A communication mode state detection unit 240 and a display unit 250 for displaying the detected current communication mode state to the outside.

The barcode determining unit 220 may compare the barcode data input from the barcode scanner with the conversion barcode stored in advance in the storage unit 260 to determine whether the barcode is a conversion barcode.

When the barcode scanner is connected to the communication mode switching device 200 via the USB port, the communication mode setting unit 230 connects the barcode scanner to the USB input device by a plug and play (PnP) function, Communication can be performed. On the other hand, when receiving the switching barcode, which is a command to change from the barcode scanner to the serial communication mode in the state of being connected to the USB port, the communication mode setting unit 230 connects the barcode scanner to the serial communication port (for example, COM1) Data communication can be performed in the communication mode. In the communication mode switching recognition apparatus 200, the switching of the communication mode by the switching barcode can be set by the USB communication mode driver and the serial communication (USB-RS232) communication mode driver provided by each scanner manufacturer.

The communication mode state detection unit 240 can detect the current communication mode state set by the switching barcode between the communication mode switching recognition device and the barcode scanner. The communication mode state detection unit can generate and manage a communication mode history with the barcode scanner. The communication mode state detection unit can determine whether the communication mode switching with the barcode scanner is completed without errors according to the input switching barcode command. For example, when the currently input switching bar code command is a command to change to the serial communication mode, the communication mode state detection unit 240 detects the external device connection state information managed by the operating system of the communication mode switching recognition apparatus 200 Is Windows (TM), it can detect whether the current barcode scanner is connected to the USB device or the serial port by using the device manager information), and confirm that the communication mode is switched according to the input conversion barcode command. In addition, when the communication mode conversion recognition unit is not connected to the bar code scanner through the external device connection status information, or when the communication mode according to the conversion bar code command is not switched (for example, If the bar code command is a command for changing to the serial communication mode, it is detected that the bar code scanner is not connected to the serial communication port according to the error of the communication mode setting driver). When the operator confirms the recognition failure information through the display unit during the barcode scan operation, the operator immediately stops the product barcode scan operation, thereby preventing the product production history omission due to the communication mode switching error.

When the operator has scanned the switching bar code through the bar code scanner, the communication mode switching recognition device 200 detects the current communication mode with the connected bar code scanner and can immediately notify the operator of the detected communication mode information through the display unit. The operator can accurately operate the product bar code input by recognizing that the communication mode between the bar code scanner and the communication mode conversion recognition device has been changed according to the scanned conversion bar code. Therefore, in order to scan a product barcode for each product conveyed in the conventional conveyor, a product barcode is read by one barcode scanner without missing and sent to an MES server without requiring a plurality of barcode scanners corresponding to each communication mode, Can be improved.

3 is a flowchart illustrating a method of verifying that the communication mode of the barcode scanner has been switched according to an embodiment of the present invention.

As shown in FIG. 3, when the communication mode switching is required according to the product and operation state, the operator receives the barcode data scanned from the barcode scanner by scanning the conversion barcode using the barcode scanner S31). If the communication mode switching recognition device continuously compares the inputted barcode data with the switching barcode stored in advance in the storage unit and determines that the barcode data is a switching barcode (S32), it switches the device connection setting with the barcode scanner in the communication mode according to the switching barcode (S33). Continuously, the communication mode switching recognition device confirms the current communication mode connection state according to the switching of the communication mode with the barcode scanner (S34), and displays the confirmed current communication mode on the display part and notifies the operator immediately. The communication mode switching recognition apparatus displays the recognition failure information through the display unit when the communication mode switching recognition apparatus is not connected to the barcode scanner or when the communication mode is not switched to the communication mode according to the switching barcode command using the external device connection state information can do. Meanwhile, if the communication mode switching recognition device determines that the input barcode data is not a conversion barcode (S32), it can manage the product production history by transmitting the received product barcode data to the MES server (S36).
