본 발명은 작업관리시스템에서 휴대 바코드스캐너(portable barcode-scanner) 운용 방법에 관한 것으로, 특히, 바코드 정보를 이용하는 작업관리시스템에서 작업 진행 방식을 개선함으로써 휴대 바코드스캐너의 사용을 최소화 하고 휴대 바코드스캐너 없이도 작업자가 작업을 진행할 수 있도록 하는 휴대 바코드스캐너 운용 방법에 관한 것이다.
The present invention relates to a method of operating a portable barcode scanner in a task management system, and in particular, by improving the operation process in a task management system using barcode information, minimizing the use of the portable barcode scanner and without a portable barcode scanner. The present invention relates to a method of operating a portable barcode scanner that allows an operator to carry out work.
종래의 휴대 바코드스캐너를 사용하는 작업관리시스템에 있어서는, 작업자가 작업 시 항시 휴대 바코드스캐너를 들고 다니면서 작업에 사용하였다. 예로, 장치ㅇ설비를 사용하는 경우, 휴대 바코드스캐너를 PDA(Personal Digital Assistant)에 연결하여 그 PDA로부터 장치ㅇ설비의 바코드를 입력 받아 작업 결과를 저장했다.In a work management system using a conventional portable barcode scanner, a worker carries the portable barcode scanner at all times during work to use it for work. For example, when using a device, a portable barcode scanner was connected to a PDA (Personal Digital Assistant) to receive a bar code of the device from the PDA and stored the work results.
이와 같은 종래의 기술에 있어서는, 장치ㅇ설비를 작업에 사용할 때마다 PDA에 휴대 바코드스캐너를 장착해서 작업을 해야 하기 때문에, 작업이 매우 불편하다.
In this conventional technique, the work is very inconvenient because the portable bar code scanner must be attached to the PDA every time the device is used for work.
본 발명은 작업관리시스템에서 바코드 정보를 이용함에 있어서, 서버(server), PDA, 휴대 바코드스캐너를 사용하는 방식을 개발하여 작업 효율을 향상시키는 작업관리시스템에서 휴대 바코드스캐너 운용 방법을 제공하는데 그 목적이 있다.
An object of the present invention is to provide a method for operating a portable barcode scanner in a task management system that improves work efficiency by developing a method of using a server, a PDA, a portable barcode scanner in using a barcode information in a task management system. There is this.
이하, 첨부된 도면을 참조하여 본 발명에 따른 실시 예를 상세히 설명하면 다음과 같다.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 바코드 정보를 휴대 바코드스캐너로 입력받아 PDA 및 서버를 통해 데 이터베이스(database)에 저장하는 과정을 나타낸 개략도로, 무선 통신이 가능하고, 외부 장치와 연결할 수 있는 내장된 인터페이스를 통해 휴대 바코드스캐너와 연결하여 장치나 설비의 바코드를 읽어 들일 수 있고, 바코드와 장치나 설비의 정보를 조합하여 저장할 수 있는 PDA와, 작업에 필요한 정보들을 데이터베이스에 저장하고, PDA와 무선 통신으로 연동되어 작업의 진행사항 및 정보를 수신하고, 작업의 변경된 내용 및 바코드 정보를 PDA에 송신하는 서버로 구성된다. 상기 데이터베이스는 서버 내에 구성될 수 있다.1 is a schematic diagram illustrating a process of receiving barcode information into a portable barcode scanner and storing the information in a database through a PDA and a server. The portable communication is possible through a built-in interface capable of wireless communication and connecting to an external device. It is possible to read barcode of device or equipment by connecting with barcode scanner, and to save barcode by combining barcode and information of device or equipment, and to store information necessary for work in database, and work with wireless communication with PDA It consists of a server that receives the progress and information of, and transmits the changed content and barcode information of the job to the PDA. The database can be configured in a server.
동 도면에 있어서, 작업용 장치나 설비를 분배할 경우, 작업자는 창고에 배치되어 있는 휴대 바코드스캐너를 장착하여 장치에 부착된 바코드를 읽어 들여서 PDA에 바코드 값과 장치의 정보를 저장한다(S1). 이 때 바코드 정보에 상태값("전송전")을 주어 서버와의 동기에 사용한다.In the figure, when distributing a work device or equipment, a worker is equipped with a portable barcode scanner arranged in a warehouse, reads a bar code attached to the device, and stores the barcode value and information of the device in the PDA (S1). At this time, the status value ("before transfer") is given to the barcode information and used for synchronization with the server.
PDA에 작업 정보를 입력하기 위해 작업자는 PDA의 무선 통신 기능을 이용해서 서버에 접속한다. PDA는 서버에 접속되면 저장된 장치의 정보들을 조회하여 서버에 보고되지 않은 장치의 정보(상태값이 "전송전"인 정보)를 서버로 전송한다(S2). 이 때, 서버는 PDA로부터 수신한 장치 정보에서 바코드 값의 정합성을 체크한다.To enter job information into the PDA, the operator connects to the server using the PDA's wireless communication capabilities. When connected to the server, the PDA inquires the information of the stored device and transmits the information (information whose status value is "before transmission") of the device which is not reported to the server (S2). At this time, the server checks the consistency of the barcode value in the device information received from the PDA.
서버는 바코드 값에 오류가 없으면 자신의 데이터베이스에 저장(S3)하고 바코드 값에 오류가 있으면 PDA에게 오류를 인지시켜서 잘못된 바코드를 작업자가 다시 입력할 수 있도록 한다. 서버는 작업자에 할당된 작업 정보를 조회해서 PDA로 전송한다. 이 때, 서버는 PDA에서 전송된 바코드 정보의 상태값을 "전송됨"으로 변 경한다.If there is an error in the barcode value, the server stores it in its database (S3). If there is an error in the barcode value, the server notifies the PDA of the error so that the operator can input the wrong barcode again. The server inquires the work information assigned to the worker and sends it to the PDA. At this time, the server changes the status value of the barcode information transmitted from the PDA to "sent".
작업자는 PDA에 저장된 작업 정보를 이용해서 작업을 진행하고 필요한 장치를 사용한다. 사용한 장치는 PDA에 저장된 장치 리스트에서 선택하여 작업에 사용했음을 PDA에 저장한다. 작업의 진행 결과를 PDA에 저장한 후, 작업자는 PDA를 사용하여 서버에 접속한다.The worker proceeds with the job information stored in the PDA and uses the necessary device. The device used is selected from the list of devices stored on the PDA and stored on the PDA that it has been used for the job. After saving the work progress on the PDA, the worker connects to the server using the PDA.
PDA는 서버에 접속되면, 작업 결과 정보를 서버에게 보고하고, 사용한 장치의 정보도 서버로 전송한다. 서버는 PDA로부터 받은 작업정보를 데이터베이스에 저장하고, 수신한 바코드 정보에 해당하는 서버에 저장된 장치의 데이터를 "사용했음"으로 변경한다.When the PDA is connected to the server, it reports the work result information to the server, and also transmits the information of the used device to the server. The server stores the job information received from the PDA in the database, and changes the data of the device stored in the server corresponding to the received barcode information to "used".
상술한 과정에 의해서 작업자는 장치 창고에서 바코드 입력 작업 후, 휴대 바코드스캐너를 사용할 필요없이 작업을 진행할 수 있다.By the above-described process, the operator can proceed after the barcode input operation in the device warehouse, without the need to use a portable barcode scanner.
그러나, PDA는 하드웨어 및 소프트웨어적 특성상 저장하고 있는 정보를 유실할 소지가 있다. 이와 같은 경우 휴대용 바코드스캐너를 사용해서 장치 정보를 다시 입력할 필요가 있는데, 본 발명에서 이를 해결할 것이다.However, PDAs may lose their stored information due to hardware and software characteristics. In such a case, it is necessary to re-enter the device information using a portable barcode scanner, which will be solved by the present invention.
도 2는 PDA에서 바코드 정보가 유실되었을 때 서버로부터 저장된 바코드 정보를 전송받아 바코드 정보를 복구하는 과정을 나타낸 개략도이다.2 is a schematic diagram illustrating a process of recovering barcode information by receiving stored barcode information from a server when barcode information is lost in a PDA.
동 도면에 있어서, PDA에서 정보가 유실된 경우, 작업자는 PDA를 사용하여 서버에 접속해서 작업 정보 및 장치 정보를 서버에게 요청한다(S1). 서버는 데이터베이스에서 작업자의 작업 정보를 조회하여 PDA로 전송하고, 서버가 작업자의 요청에 의해서 데이터베이스에 기 등록해 둔 장치들의 리스트에서 사용하지 않은 바코 드 값들을 조회(S2)하여 PDA로 전송한다(S3).In the figure, when information is lost in the PDA, the worker connects to the server using the PDA and requests the server for job information and device information (S1). The server inquires the worker's work information from the database and sends it to the PDA, and the server inquires (S2) unused barcode values from the list of devices previously registered in the database at the request of the worker and sends them to the PDA ( S3).
작업자는 이와 같은 과정을 통해 PDA에서 유실된 데이터를 복구한다. 따라서, 작업자는 다시 수신한 정보들을 이용해서 작업을 진행할 수 있다.This process recovers lost data from the PDA. Therefore, the worker can proceed with the work using the received information again.
상술한 도 1과 도 2의 동작설명을 도 3과 같은 순서도에 의해 단계별로 나타낼 수 있다.The above-described operation of FIG. 1 and FIG. 2 can be shown step by step with the flowchart shown in FIG. 3.
도 4는 본 발명에 따른 작업관리시스템을 나타낸 개략도로, 통신서비스 가입자 댁내의 서비스 개통, 수리 작업을 하는 작업관리시스템에 적용할 수 있다.4 is a schematic diagram showing a work management system according to the present invention, which can be applied to a work management system for opening and repairing a service in a subscriber's home of a communication service.
전국의 장치 정보를 관리하는 서버를 두고, 중간에 중계 서버를 통해 각 지역의 작업 정보 및 바코드 정보를 관리한다. 전국을 일정 단위의 작업구역으로 나누고 구역마다 장치 관리 창고를 두어 작업자들에게 바코드가 부착된 장치들을 분배한다.It has a server that manages device information of the whole country, and manages job information and barcode information of each region through a relay server in the middle. The country is divided into a number of work zones and device management warehouses are located in each zone to distribute workers with barcoded devices.
작업자들이 PDA에 입력한 바코드 정보들은 각 지역의 중계서버에 저장되고 중계서버들은 PDA로부터 수신 받은 바코드 정보를 전국 장치 관리 서버에 전송한다. PDA와 중계서버는 매 무선 통신시에, 중계서버와 전국 장치관리 서버는 일정 간격의 시간을 두고 동기화 된다.
Barcode information that workers input into PDA is stored in relay servers in each region, and relay servers transmit barcode information received from PDA to device management servers nationwide. The PDA and the relay server are synchronized at every wireless communication, and the relay server and the nationwide device management server are synchronized at regular intervals.
