Bluetooth (Bluetooth) is the technical standard of the near radio digital communication jointly proposed in May, 1998 by Toshiba, Ericsson, IBM, Intel and Nokia.It utilizes short-range wireless link to replace private cable, not only removes the trouble connected each other from, and is convenient to people in indoor or outdoor flow operation.Be with a wide range of applications, be just subject to the extensive concern of global all circles.
If bluetooth can be utilized to set up industrial control equipment on wireless network mode coupled columns carry out safeguarding, patrol and examine and the operation such as upgrading, to have good exploitativeness, for outdoor equipment adjustment and installation is provided convenience, the equipment that eliminates closely is debugged, ensure that personal safety, this is very significant.
Summary of the invention
For solving the problem, the present invention proposes a kind of method of being carried out industrial equipment maintenance on post by blue tooth wireless technology, comprising following steps:
The default unlatching Bluetooth function of industrial equipment on step 1. post is also in listening state;
The bluetooth of industrial equipment on Bluetooth function search post opened by step 2. notebook computer;
Step 3. notebook computer input pairing code, on post, industrial equipment is verified this pairing code;
Step 4. is matched code and is proved to be successful industrial equipment on rear notebook computer and post and all creates a Bluetooth virtual network interface card and be in connection status;
On step 5. post, industrial equipment is notebook computer distributing IP address, sets up blue teeth wireless local area network (LAN) between the two;
Safeguarded by industrial equipment on blue teeth wireless local area network (LAN) coupled columns between step 6. notebook computer, patrol and examine and the operation such as upgrading.
In described step 4, on post, industrial equipment and notebook computer are embodied as Bluetooth virtual network interface card by driver bluetooth module.
Said method adopts the BNEP based on Bluetooth technology that post builds blue teeth wireless local area network (LAN) between industrial control equipment and notebook computer.
In the present invention, on post, industrial equipment and notebook computer are embodied as Bluetooth virtual network interface card by driver bluetooth module, set up WLAN (wireless local area network) between, utilize this WLAN (wireless local area network) engineers and technicians can complete malfunction elimination, the work such as maintenance and upgrading of industrial equipment on coupled columns under post, greatly provide the maintainability of industrial equipment on post, personnel do not need upper prop to carry out plant maintenance, ensure that personal safety.

Fig. 2 is industrial equipment workflow diagram on post.
Fig. 3 is working with notebook computer flow chart.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Main purpose of the present invention adopts Bluetooth technology as local wireless communication channel, utilizes industrial control equipment on network mode coupled columns to carry out safeguarding, patrols and examines and the operation such as upgrading.
For achieving the above object, technical scheme of the present invention is achieved in that
BNEP(bluetooth network encapsulation protocol based on Bluetooth technology), blue teeth wireless local area network (LAN) is built between the notebook computer that industrial control equipment on post and technical staff carry, technical staff is logged in, to carry out the operations such as malfunction elimination, plant maintenance and function upgrading by industrial equipment on conventional network operation instrument (telnet, ssh etc.) coupled columns.
On post of the present invention, the blue tooth radio network protocol hierarchy of industrial equipment and notebook computer as shown in Figure 1.
Under network layer (IP layer), three levels are set, BNEP and service discovery protocol (SDP) layer, L2CAP layer (logical link control and adaptation protocol layer), hardware baseband layer from top to bottom successively, corresponding between each level of procotol of industrial equipment and notebook computer.The connection of the Bluetooth wireless communication channel that post is formed between industrial equipment and notebook computer is realized between described hardware baseband layer.
In this programme, do not need between IP layer and L2CAP layer to insert PPP and RFCOMM layer, and complete by from IP layer to the mapping network protocol hierarchy of L2CAP layer.
On post, the transfer of data operation principle of industrial equipment and notebook computer is as follows:
On post, the BNEP layer of industrial equipment and notebook computer provides the conversion of bluetooth protocol repertory and ICP/IP protocol stack, and it encapsulates with IEEE802.3 Ethernet and supports same Upper Level Network Protocol.The MTU of BNEP Jing Hequ is decided to be 1691 bytes, and can ensure the disposable transmission of the ether layer package that network layer sends so downwards, such network struction scheme effectively improves the communication usefulness of wireless network.In data transmission, BNEP directly accepts the Ether frame that IP layer sends downwards, and this ether Jing Hequ is directly copied to BNEP Jing Hequ, sends to L2CAP layer after adding BNEP head.Be converted to wireless signal by hardware baseband layer after L2CAP layer receives data and send to opposite end bluetooth accepting device.
On post, industrial equipment and notebook computer are embodied as Bluetooth virtual network interface card by driver bluetooth module, are equivalent to the function of one piece of true network interface card.
In actual use, on post, industrial equipment workflow as shown in Figure 2 in the present invention: default unlatching Bluetooth function is also in listening state, when there being bluetooth equipment to attempt pairing, attempts matching by according to the pairing code of the other side's bluetooth equipment.If successful matching will create the Bluetooth virtual network interface card matched with this bluetooth equipment and be in connection status.Then DHCP SERVER function is opened, to be the other side's bluetooth equipment distributing IP address.
The present invention in actual use, working with notebook computer flow process as shown in Figure 3: the bluetooth at industrial equipment place on Bluetooth function search post opened by notebook computer, and after finding, namely input pairing code is verified for industrial equipment on post.Being proved to be successful by Microsoft Loopback Adapter corresponding for establishment this bluetooth equipment on rear notebook computer, and carrying out the application of the DHCP network address to industrial equipment on post, applying for successfully, notebook computer and post communicating setting up blue teeth wireless local area network (LAN) between equipment.
The embodiment of the present invention belongs to outdoor, carries out maintenance debugging by the mobile notebook of Bluetooth function to Standard type equipment.It is also always standby that Standard type equipment has Bluetooth function.Standard type industrial equipment is embodied as Bluetooth virtual network interface card bluetooth module by program, is equivalent to the function of one piece of true network interface card.
Outstanding advantages of the present invention is: the present invention utilizes Bluetooth technology to make post sets up WLAN (wireless local area network) between industrial equipment and mobile notebook, engineers and technicians can complete malfunction elimination, the work such as maintenance and upgrading of industrial equipment on coupled columns under post, greatly provide the maintainability of industrial equipment on post, eliminating engineering staff needs upper prop to carry out plant maintenance, ensure that personal safety.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
