Block quickly and accurately accesses the purpose of test point, improves testing efficiency.
Description of the drawings
Fig. 1 is communication system schematic diagram.
Specific embodiment
The present invention is described in further detail below by specific embodiment combination attached drawing.
By on hardware to communication bus spatial arrangement physical space carry out it is self-defined and on software to communication
Transport protocol is deformed, and the data ID that stationery communication transport protocols are transmitted is enable directly to react communication bus in spatial arrangement
Physical spatial location, when making the external test module of communication bus, test module obtains the physical spatial location automatically, and based on should
Whether physical spatial location, which matches, decides whether to obtain test command so that, same physical spatial location can realize difference in functionality
Test, also quickly test module can be accurately positioned based on physical spatial location, meanwhile, also facilitate control terminal in software
The rewriting of aspect, e.g., the test very to same physical spatial location difference in functionality only need to change test command.
This example provides a kind of communication system to test module three-dimensional fix, and schematic diagram is as shown in Figure 1, including control
End processed, master control borad, can buses and several test modules.
Wherein, master board in can bus registers self-defined can buses spatial arrangement physical spatial location,
And the physical layer protocol of corresponding can buses is formulated according to the physical spatial location of setting, pass the physical layer protocol of can buses
Defeated data ID directly reacts physical spatial location of the can buses in spatial arrangement；By the physical layer protocol to can buses into
Row deformation makes to carry physical spatial location of the can buses in spatial arrangement in physical layer protocol, specifically, can bus registers
Logic analysis is currently only used for, is to modify to the content of can bus registers inside points storage in this example, its content is repaiied
The coordinate of XYZ axis is changed to, and combines ARM chips and carries out physical space positioning.
Specifically, all the way can buses include both threads, master control borad by every single line spatial arrangement three-dimensional coordinate (X,
Y, Z) it is stored in the register of can buses；The communication interface of can buses is provided with and its own corresponding physical space position
It puts, e.g., the communication interface of can buses is provided with locating module, which is stored with empty with its own corresponding physics
Between position, correspondingly, test module is built-in with ARM chips, and other by ARM chips draw angle and are arranged to coordinate and draw angle, work as survey
When die trial block is inserted into locating module, test module draws the physical spatial location in angle acquisition locating module by the coordinate；Work as master
After control plate receives the test command of control terminal transmission, which by corresponding can bus physicals layer protocol is transmitted, is hung over
After test module in can buses reads the data ID of can bus transfers, pass through the location information for carrying data ID and itself
Location information matched, if position is identical, the operational order that test module is set according to inside performs corresponding survey
Examination operation, otherwise, which is failure to actuate.
In addition, in order to increase the convenience of the handling capacity of data and control, every can buses all the way of the spatial arrangement of this example
Including at least two groups of can buses, wherein, one group of can bus transmits data, another group of can for master board to test module
Bus is used for test module to master board feedback data；In other embodiments, multigroup can be increased according to actual needs
Bus is for transmission, feedback data.
Since the data bit of can bus transfers is 8, in order to according to actual needs, break through the transmission of 8 data, this example
The physical layer protocol of can buses also formulated multiframe identifier, which passes for identifying multiframe transmission and single frames
It is defeated, when being transmitted for multiframe, first multiframe is divided into transmit the data of transmission, is remerged after end of transmission, in this way, overcoming
The shortcomings that can buses can only be transmitted less than equal to 8 byte data realizes the transmission of the data more than 8 bytes.
Further, the test module of this example is unitization standard module, to realize the unitization by multiple test modules
Combination avoids a problem of test module can only realize single test function to realize the tests of other functions, meanwhile,
Making full use of for test module is realized, avoids the waste of test module.
Further, in order to realize that the various test datas by test module preserve, so as to staff's post analysis,
Purposes, this example such as inquiry further include home server and cloud server, and control terminal is led to home server and cloud server
News connection, in this way, the test data that control command and test module that control terminal is sent to are fed back to it is transmitted in real time
Home server and cloud server, so as to staff's local search and remote inquiry.
Use above specific case is illustrated the present invention, is only intended to help to understand the present invention, not limiting
The system present invention.For those skilled in the art, thought according to the invention can also be made several simple
It deduces, deform or replaces.
