Step 206 determines that short trouble occurs in the route to be detected there are line fault.
Step 207 determines that open circuit fault occurs in the route to be detected there are line fault.
In step 201, optionally, parallel transmission transmits 1 as unit of byte in a set transmission cycle
Byte, 2 bytes or more multibyte, each byte include 8 data.When transmitting 1 byte in a transmission cycle, N
Take 8,8 route parallel transmissions to be detected at least one group of 8 bit test data.When transmitting 2 bytes in a transmission cycle, N
Take 16,16 route parallel transmissions to be detected at least one group of 16 bit test data.Wherein, bit (bit) is that computer is counted
According to the minimum unit of transmission, one is single binary number than refering in particular to, such as 0 or 1.Assuming that data to be transmitted are pixel
The pixel data that value is 99, converts binary number for the pixel value and obtains 01100011, when using 8 route parallel transmissions,
The bit value of every line transmission is a bit, such as 0 or 1.It can be as shown in figure 3, with 8 data of D7-D0 label
Transmission line, when transmitting terminal is by the 8 data transmission line parallel transmission such as D7-D0, binary number is from least significant bit
(Least SignificantBit, LSB) by D0 line transmission, most significant bit (Most Significant Bit, MSB) by
D7 line transmission.
It in step 202, optionally, can be to every in N item route to be detected in transmission process or when the end of transmission
The actual bit value of one line transmission to be detected is counted, total with the actual bit of determination every line transmission to be detected
Value.Optionally, the mode of statistics can be cumulative mode, by the actual bit in each transmission cycle to a detection line transmission
Value carries out the cumulative actual bit total value that can determine the line transmission to be detected of this in entire transmission process.
Optionally, theoretical bit total value can be determined according to the data task amount that each route to be detected need to transmit.For example,
The binary system data to be transmitted of at least one set N can be determined according to the numerical value of data to be transmitted；Then, according to least significant bit

In certain difference.Therefore, when judging whether route is abnormal, line transmission characteristic is accounted for into range, is conducive to be promoted
The accuracy of detection.
Specifically, according to the line transmission characteristic of route to be detected, it may be determined that the transmission range of tolerable variance of route to be detected；Hold
Poor range is it is to be understood that under the influence of route transmission characteristic, actual bit total value and transmitting terminal pair that receiving end receives
The reasonable floating range of difference between the bit total value answered.If difference is in reasonable floating range, then it is assumed that the difference is not line
Caused by the failure of road, but as caused by line transmission characteristic.After determining the transmission range of tolerable variance of route to be detected, it is based on
The range of tolerable variance, it may be determined that judgment threshold.Such as can be directly using the range of tolerable variance as judgment threshold, or the appearance will be slightly larger than
Upper limit value of the value of poor range limit as judgment threshold, using the value of the slightly smaller than lower limit of the range of tolerable variance as judgment threshold
Lower limit value.
Optionally, it in step 205- step 207, is determining there are after the route to be detected of line fault, it can be into one
There are any failures for step judgement.
Specifically, the transmitted bit total value of the route to be detected of line fault is greater than its theoretical bit total value if it exists,
Then it is believed that short trouble occurs in the route to be detected there are line fault, draw while transmitting this route corresponding bit
The corresponding bit of All other routes is entered.The transmitted bit total value of the route to be detected of line fault is less than its theoretical bit if it exists
Total value is lost part ratio then it is believed that open circuit fault occurs in the route to be detected there are line fault in transmission process
It is special.

When the grayscale image of rank composition, the value of multiple groups N data to be transmitted is different according to color range and is varied, so that N item passes
Defeated pin can transmit different binary numbers, to promote the reliability for the actual bit total value that statistics obtains.
A kind of optional test pattern can enter as shown in figure 4, altogether comprising 12*12=144 pixel Pixel, it is assumed that often
The pixel value of a pixel is 79.Being converted to binary number for 79 is 01001111.Pass through D7-D0 on imaging sensor etc. 8
When item transmission pin transmits each pixel value, the statistic processes of the corresponding theoretical bit total value of every transmission pin can be such as
Shown in Fig. 5.In such as Fig. 5, the corresponding theoretical ratio of every transmission pin is can be obtained in the binary number for every transmission pin transmission that adds up
Special total value.For example, it is 144 that the corresponding theoretical bit total value of D7, which is the corresponding theoretical bit total value of 0, D0,.
Likewise, the actual bit total value that the above method calculates D7-D0 transmission can be used in receiving end, it is every by comparing
The actual bit total value of data line and theoretical bit total value, it may be determined that abnormal route in D7-D0.
