[embodiment]
The present invention provides the information acquisition of a kind of trouble spot, compression and transmission method for remote equipment.In the method, first encoded in Devices to test trouble spot, and fault acquiring terminal I/O is connected with equipment failure point.Fault acquiring terminal and equipment coordination work, in equipment operation process, with period tau to trouble spot information.Fault acquiring terminal change-over circuit changes into the digital quantity signal collecting and analog signals the data that computing machine can be stored.Effective and invalid two kinds of features according to digital quantity signal, 1 railway digital amount signal is changed into 1 bit data by change-over circuit, and analog signals is required to change into 8 bit data according to data precision.Compression Processing Algorithm is to adjacent same Value Data and do not configure collection I/O, carries out effectively compression and processes.Central server and acquisition terminal adopt C/S framework communication mode, and fault information acquisition end is integrated with 3G or 4G communication module, by socket sockets interface, adopt Transmission Control Protocol to create the transmitting link between server.Central server detects after terminal connection request, sends authentication instruction to terminal.After to be certified passing through, between fault information acquisition terminal and server, can carry out the transmission of data.Acquisition terminal is accepted the instruction of central server, and according to instruction dispatching centre server information needed.
Be illustrated in figure 1 a kind of remote fault information and gather compression transmitting method system framework figure, wherein detail display three included parts of a kind of remote fault information acquisition system, the result that wherein each part produces is as the object of next partial data processing.
What first part was carried out is data acquisition, and fault acquiring terminal is with period tau to trouble spot information, and change-over circuit changes into the digital quantity signal collecting and analog signals the data that computing machine can be stored.Effective and invalid two kinds of features according to digital quantity signal, 1 railway digital amount signal is changed into 1 bit data by change-over circuit, and analog signals is required to change into 8 bit data according to data precision.What Part II carried out is data compression process, and fault acquiring terminal configuration device fault to be collected is counted, and its data bit of configuration collection I/O is not empty, the effective and invalid feature according to digital quantity signal, scale-of-two bit data representation for digital quantity signal.Adjacent with value and do not configure I/O null value situation and compress processing to acquisition terminal failure message.What Part III carried out is data transmission, and fault acquiring terminal, by 3G or 4G communication mode, carries out authentication and discriminating with failed server center, center, and sets up with it reliable transmission link.Central server sends command adapted thereto to fault acquiring terminal, and fault acquiring terminal is made respective handling according to command request, upload fault data can according on a time period or the mode such as real time new data upload.Central server receives the fault data that acquisition terminal sends, and it is carried out to decompression.Search database table with device id number, to form, store fault data into associated databases table with trouble spot coding and numerical value.Device fabrication business after sale personnel passes through IE browser access central server, inquire about specific certain time period of certain product or trouble spot real time new data according to producer's (numbering), device class (numbering), unit type (numbering), with judgment device trouble spot and fault type, and make in time respective handling.
As shown in Figure 2, be a kind of trouble spot information acquisition algorithm flow chart, its key step is:
Step 11: fault acquiring terminal reads configuration information table, carries out initialization to collection I/O port etc.
Step 12: fault collection end gathers digital quantity, analog signals according to allocation list, CAN extend information, RTC etc.
Step 13: judge that whether current Information Monitoring is identical with last information.When new record records identically with old, abandon new record; When new record records differently from old, after will new record arranging, write SRAM.
Step 14: judge that whether SRAM data working area is full, if SRAM data working area is full, calculate FLASH start address and end address, disposable SRAM content scrolling is covered to burned FLASH, otherwise write SRAM data working area after arranging wait holding the record.
Step 15: task process is hung up, and waits for about 500ms, task process continues circle collection storage data.
If Fig. 3 is failure message recording compressed Stored Procedure figure, its key step is:
Step 21: task process takes out a record from SRAM, resolves according to allocation list.
Step 22: task process reads a data bit of record, compares the value of itself and a upper data bit.If identical, run into that adjacent counter adds up with value, and continue to read and record next data bit; If adjacent place value difference, illustrates that compressible same value situation finishes, preserve by this phase data place value and with value accumulator computes value, continue to read next data bit.Recorded bit is read in task process circulation, records tail until arrive, and the new record after compression is preserved to meeting SRAM.Step 3: continue to take out record from SRAM, loop compression and process.
If Fig. 4 is the process flow diagram that fault information acquisition end and central server carry out data transmission, its key step is:
Step 31: fault information acquisition end enables 3G/4G communication module, whether judgement is uploaded switch and is opened, if close the process that ends task, judges communication module connection status if open with AT instruction, module working condition, and whether network state is normal.、
Step 32: network state parameter is normal, removes Status Flag, configuration module mode of operation,
The parameter such as server ip, port, the TCP connection request by the initiation of socket sockets interface with server.
After step 33:TCP connecting link is set up, fault information acquisition end is initiated authentication request to central server, and central server carries out respective acknowledgement response, checking client identity.
Step 34: after certification is passed through, fault information acquisition terminal uploading device type, numbering and this machine information, port uses configuration information table;
Step 35: fault information acquisition terminal sends compression storage data to central server, and central server carries out corresponding decompression according to configuration information table, and failure logging information is stored in corresponding database table.
The present invention, by fault information acquisition terminal, is connected to trouble spot to be measured signal, can gather Devices to test digital signal and simulating signal.Gather the data of returning through overcompression processing, fault information data is taken up room and reduce in a large number.The fault information data that acquisition terminal is processed compression by 3G/4G module sends central server to, after-sales service personnel can pass through the mode of querying server relevant information, understand fast remote mechanical trouble spot information, auxiliary its carries out localization of fault and failure judgement reason.Data compression transmission mode can effectively reduce transmission bandwidth demand, improves the real-time that data acquisition is reclaimed.With existing with compared with class methods, the trouble spot failure message amounts many, that produce that the method can gather are few, thereby improve the traffic load between fault information acquisition terminal and central server, can offer in time the effective failure message of personnel after sale, assist and carry out fault diagnosis and related service support.
The foregoing is only better enforcement use-case of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment of doing, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
