Abstract
The invention discloses a data acquisition method for an excavator and the excavator using the method, and belongs to the technical field of data information processing. The method comprises the following steps of: 1, data encryption, namely an excavator controller encrypts transmitted excavator data according to an encryption algorithm; 2, pairing of Bluetooth equipment and matching of the excavator, namely the excavator controller transmits a connection request data frame, and after receiving data frame information for requesting connection, a detection device with a Bluetooth module compares the data frame information with preset information; 3, data reception, namely the detection device responds if the preset information is the same as the received data frame information, otherwise does not respond; and 4, data decryption, namely the detection device receives the excavator data after responding, and decrypts the excavator data according to the encryption algorithm. A Bluetooth technology is used for encrypting the data before the data is transmitted and decrypting the data after the data is transmitted, so that information transmission security is ensured.
Description
Technical field
The present invention relates to the processing data information technical field, relate in particular to a kind of excavator data acquisition method and use the excavator of this method.
Background technology
At present, along with the development of construction machinery industry, after-sale service also is greatly improved.Wherein, be used to detect the portable detector of excavator operation information and failure diagnosis, because advantages of small volume and easy and simple to handle plays very important effect to the raising of after-sale service quality.
The detecting instrument that existing domestic and international excavator producer develops generally all adopts controller local area network (Controller Area Network; CAN) mode of bus communication realizes the transfer of data between controller for excavators and the detector; Because the CAN bus has versatility, causes the data leak on the bus easily.Also have a kind of detector that adopts Bluetooth technology to come Data transmission on the market,, also be easy to cause the leakage of information owing to adopt simple Bluetooth technology.Therefore need a kind of safe information transmission mode to carry out transfer of data.
Summary of the invention
In order to solve the problem that existing C AN bus communication and Bluetooth technology communication meeting cause transmitting data leak, a kind of excavator data acquisition method is provided at present and uses the excavator of this method.Concrete technical scheme is following:
A kind of excavator data acquisition method is provided at present, and said method has following steps:
The first step: data encryption, controller for excavators carries out encryption to the excavator data of sending according to AES;
Second step: the pairing of bluetooth equipment and the coupling of excavator, controller for excavators sends the connection request Frame, compares with its preset information after the Frame information that the checkout gear request of receiving of band bluetooth connects;
The 3rd step: receive data, the checkout gear preset information is identical with the Frame information of receiving, then replys, otherwise does not response;
The 4th step: data decryption, after replying, device receives the excavator data, carry out decryption processing according to confidentiality algorithm.
Further technical scheme, the transfer of data after the said deciphering show that to display device the user accurately learns excavator information through the inquiry code definition.
Further technical scheme, said display device is LCD (Liquid Crystal Display, a LCD) display screen.
Further technical scheme, said checkout gear comprises keyboard and microcontroller.
The invention also discloses a kind of excavator, said excavator has used above-mentioned each described excavator data acquisition method.
Compared with prior art; A kind of excavator data acquisition method that technique scheme provides and use the beneficial effect of the excavator of this method to be; Through before Bluetooth technology transmission data, data are encrypted and transmit data after data are deciphered, guaranteed the fail safe of message transmission.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the data acquisition system sketch map that the embodiment of the invention provides
Fig. 2 is the checkout gear bluetooth coupling flow chart that the embodiment of the invention provides;
Fig. 3 is the controller for excavators data encryption flow chart that the embodiment of the invention provides;
Fig. 4 is the detector data decryption flow chart that the embodiment of the invention provides.
Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
As shown in Figure 1, embodiment of the invention detection system comprises controller for excavators, detector, display device and other external equipment, and wherein controller for excavators and detector all have bluetooth equipment, can carry out bluetooth communication.
As shown in Figure 2; Near the search in real time of the pairing of bluetooth equipment and the coupling of excavator, controller for excavators bluetooth equipment is when searching bluetooth equipment; Automatically send the connection request Frame, this Frame includes the numbering of excavator and the date of manufacture of excavator.Behind the Frame that the checkout gear request of receiving connects, information and its preset information of this Frame compared, if identical information is arranged, then reply, and receive data, store in real time, then end.If Frame information is different with the checkout gear preset information, then directly finish.
As shown in Figure 3, before controller for excavators sends data, need carry out encryption according to AES to the data message that sends, carry out the bluetooth coupling with detector then, will encrypt good data after the Bluetooth pairing success and carry out Bluetooth transmission.
As shown in Figure 4, after detector and the success of controller for excavators Bluetooth pairing, begin to receive ciphered data, then ciphered data is deciphered through AES, and the transfer of data after will deciphering shows to display device.Wherein, display device is preferably LCD display, and checkout gear comprises keyboard and microcontroller and other external equipment.The data that demonstrate according to display screen at last, the user accurately learns excavator information parameter and failure diagnosis information through the inquiry code definition.
The invention also discloses a kind of excavator, this excavator has used the described excavator data acquisition method of the embodiment of the invention.The excavator miscellaneous equipment can be with reference to prior art, does not do at this and gives unnecessary details.
The embodiment of the invention not only can detect the machine performance of excavator easily through the transmission data are carried out encryption and decryption, and the assurance machine information is not revealed, and has reduced service time, has practiced thrift cost, improves service satisfaction.
More than specific embodiment of the present invention is described in detail, but the present invention is not restricted to the specific embodiment of above description, it is just as example.To those skilled in the art, any being equal to
Revise and substitute also all among category of the present invention.Therefore, not breaking away from impartial conversion and the modification of having done under the spirit and scope of the present invention, all should contain within the scope of the invention.
