Description

一种单板电子标签读写控制系统及方法 One kind of board RFID reader control system and method

技术领域 FIELD

本发明涉及单板电子标签管理技术领域,更具体的,本发明涉及一种单板电子标签的读写控制系统及方法。 The present invention relates to the technical field of electronic tag management board, and more particularly, the present invention relates to a reader control system and method of the board of an electronic tag.

背景技术 Background technique

单板制造信息作为单板的"身份证",是单板全生命周期中唯一可追溯的标志。 Veneer board manufacturing information as "identity card", is the only board lifecycle traceability mark. 运用单板制造信息可以提升产品的安装性、可管理性以及产品全生 The use of veneer manufacturing information can improve the installation of the product, manageability, and the whole health product

命周期的维护成本和管理成本,例如:在原件返修、质量跟踪、设备文档的高效制作和刷新等方面的支撑作用。 Maintenance and administrative costs of the life cycle, for example: in the original repair, quality tracking, and efficient document production equipment and refresh supporting role and other aspects. 将所述单板的制造信息以电子标签的形式进行存储,通过对电子标签的管理实现对单板的管理,操作简单,因此越来越受到人们的重视。 The board manufacturing information stored in the form of electronic tag, the electronic tag management manage the board by a simple operation, and therefore more and more attention.

参考图l,该图为现有技术读取单板电子标签信息的流程示意图,该方法中被控单板为带有中央处理器(Center Process Unit, CPU)的单板,该方法具体包括: Referring to FIG L, flow graph prior art schematic of the board to read the electronic tag information, the process board is charged with a central processor board (Center Process Unit, CPU), the method comprises:

步骤l,主控板构造请求获取被控单板电子标签信息的报文; Step l, the main control board configured to request acquisition board controlled electronic tag information packets;

步骤2,主控板通过数据通道向被控单板发送所述请求报文; Step 2, the MPU board through the data channel to the controlled transmit the request packet;

步骤3,被控制单板解析来自主控板的所述请求报文; Step 3, is controlled from the master board Board parse the request message;

步骤4,根据所述解析后的请求报文读取本单板存储器里的电子标签信 Step 4, according to the request packet after the analysis of the single board memory in the read electronic tag letter

息; interest;

步骤5,被控单板向主控板反馈携带有所述电子标签信息的报文; Step 5, was charged to the master board Board feedback packet carrying the electronic tag information;

步骤6,主控板接收该报文后从所述该报文中解析出所述电子标签,并将所述电子标签信息发送出去。 After Step 6, the MPU receives the packet from the packet parsing out the electronic tag, the electronic tag and the information sent. 另外,上述步骤中还包括在没有消息报文传送的时候,在数据通道上需要定时传送一些握手消息,以保证两端的CPU可监测到该业务通道是正常的, 所述两端为被控单板端与主控板端。 Further, the above step further includes when there is no message packet transmission, timer transmission requires a number of handshaking messages on the data channels to be monitored to ensure that both ends of the CPU to the service channel is normal, the both ends of the single controlled and the main control board side end plate.

上述现有技术中被控单板是带有CPU的单板,但是在实现应用中,例如公司对发出的货物需要进行管理,对于存在CPU的单板,增加该电子标签功 The above-described prior art, the board is charged with a CPU board, but implemented in applications such as goods companies need to be issued by the management for the CPU board is present, increasing the power of the electronic tag

能,只需要增加一种控制报文,将货物发送时间等信息存入存储器里可以了, Can only need to add a control message, send the goods time and other information stored in the memory in it,

但是有些单板是没有CPU的单板,若要按现有技术实现不带有CPU的单板电子标签的读写,则需要为该单板增加CPU和传送报文的业务通道,增加了成本。 But some board is not the CPU board, the board to read and write electronic tags without CPU according to the prior art, the need to increase the CPU and packet transmission service channel for the board, increasing the cost .

综上,上述现有技术虽然能够实现单板电子标签的管理,但存储在如下 In summary, although the above prior art can be realized management board electronic tag, but is stored in the following

缺陷: defect:

由于现有技术中采用报文的形式传送单板电子标签信息的,需要CPU对报文进行处理,同时报文的承载通道也是必不可少的,对于没有CPU的单板, 则需要增加CPU和报文的承载通道,因此增加了成本。 Since the packets transmitted in the form of electronic tag information board employed in the prior art, the CPU needs to process packets while the packets carrying path is essential for the board is not the CPU, the CPU needs to be increased and packets carrying path, thereby increasing the cost.
