Embodiment 1

[0033] Assuming that the electronic water gauge has 10 contacts, the serial number is calibrated from 1 to 10 in order from low to high, and 4 of the contacts are invalid. When the water level reaches 6 contacts, there are 5 resistance intervals in total, from low to high. Sequentially calibrate the serial number as 1-5, there are resistance values ​​in the resistance intervals 1, 2, and 5, and the resistance intervals 3 and 4 are empty values, perform step 3.2: judge the contact between the high contact of the highest resistance interval and the lowest resistance interval Whether there is a resistance value in the lower contact, if the contact point 6 and the contact point 1 are both in contact with water and there is a resistance value, then it is determined that the water level has reached the height of the contact point 6.

Embodiment 2

[0035] Assuming that the electronic water gauge has 10 contacts, the serial number is calibrated from 1 to 10 in order from low to high. There is a leaf covered with water between the 7 contacts and the 8 contacts, and there is a resistance value. When the water level reaches the 6 contacts, There are 7 resistance intervals in total, and the sequence numbers are 1-7 from low to high. There are resistance values ​​in resistance intervals 1, 2, 3, 4, 5, and 7. Resistance interval 6 is empty, and detection contact 8 and The resistance value of contact 1, if contact 8 is not in contact with water, it is a null value, if contact 1 is in contact with water, there is a resistance value, then perform step 3.2 to delete the resistance value of the highest resistance interval stored in step 2, and return to Step 3, if there are resistance intervals of 1-5 consecutive resistance values, then the water level value read by the high contact in the highest resistance interval 5 is 6.

Abstract

The invention discloses an automatic error correction algorithm for electronic water gauge measurement, which comprises the following steps: step 1: calibrate the contacts and resistance intervals of the electronic water gauge; step 2: sequentially detect each resistance from the electronic water gauge from low to high The resistance value of the interval, and record and save; Step 3: Analyze the resistance value in the saved detection data; Step 4: Read the water level value at the high contact of the highest resistance interval. Through the above method, the electronic water gauge measurement automatic error correction algorithm of the present invention can correct the contact failure of the electronic water gauge and the failure data caused by the connection of two adjacent contacts above the water surface by debris, reduce the detection data error, and improve the failure rate. data accuracy in the case.

Description

technical field [0001] The invention relates to the field of water level sensors, in particular to an automatic error correction algorithm for electronic water gauge measurement. Background technique [0002] The electronic water gauge is a common means of measuring water level used in automatic monitoring of water conservancy. The principle is that water has resistance, so a fixed resistance is used in series with water, so that the partial pressure of water can be measured to further calculate the resistance value. [0003] The existing resistance measurement method between the contacts of the electronic water gauge only measures the resistance between two adjacent contacts, which is prone to errors, such as: a contact in the middle is broken, and a certain two adjacent contacts above the water surface The dots are connected by leaves with water. Contents of the invention [0004] The technical problem mainly solved by the invention is to provide an automatic error corr...
