(3) j = Kx (| A-m |)/A, and a detection reference value J is obtained, wherein K is a conversion factor, and the detection reference value J is a numerical value for judging the linear flatness of the concrete bridge.
9. The concrete bridge linear control measuring device of claim 8, wherein the concrete process of the horizontal abnormal signal is as follows:
comparing the detection reference value with a preset reference value, generating a normal signal when the detection reference value is less than or equal to the preset reference value, subtracting the preset reference value from the detection reference value to obtain an abnormal characteristic value when the detection reference value is greater than the preset reference value, comparing the abnormal characteristic value with the preset characteristic value, generating a normal signal when the abnormal characteristic value is less than the preset characteristic value, and otherwise generating an abnormal signal; and performing secondary judgment through the abnormal characteristic value to prevent the occurrence of the phenomenon of erroneous judgment.
10. The concrete bridge linear control measuring device of claim 9, wherein the measuring text comprises normal text and abnormal text; when a normal signal is generated, immediately editing 'the concrete bridge deck detection linearity at this time is normal, specifically J0'; or
And immediately editing 'the deviation of the concrete bridge deck detection linearity at this time, namely J1', after the abnormal signal is generated.
