Background
Because the existing portal opening detection is carried out by using a mode of combining a steel tape and a square, errors caused by human or tape precision and the like may exist. In the forklift assembling process, the portal is opened to a position too large to cause the portal or the fork frame inside to shake, and the door shelf or the fork frame inside to interfere with each other to generate large friction, so that the portal or the fork frame cannot lift uniformly. How to carry out the inspection of opening the shelves of the full stroke before the shelves are combined becomes the key. At present, the detection method for opening the door frame is to use a steel tape and a corner ruler to carry out inspection in a combined mode. During detection, generally 3 to 4 points are required to be taken in a standard length for detection, multi-point detection is required when special requirements exist, then whether the portal meets the assembly requirements or not is judged according to the detection result, and correction is carried out aiming at the problems. The defects of the detection method are as follows: 1) the single-point detection cannot reflect the change trend, and mainly the detection points of the detection method are limited, so that the change trend of the opening of the whole portal cannot be intuitively reflected. 2) The operation is inconvenient, and inspection efficiency is low, "use the mode that steel tape and angle square combine to inspect", needs two people to cooperate, alone detects promptly, and alone is supplementary, wastes time and difficultly again. 3) There is a quality risk. Due to the fact that single-point inspection is adopted, the whole change trend of the door frame cannot be reflected, the single-point detection size is possibly qualified, and the phenomenon that the door frame shakes or the gap is too tight after the door frame is combined and needs to be polished or disassembled can occur. 4) The detection is unreliable or inaccurate.
To sum up, rely on artifical manual mode among the conventional art, the portal is opened a shelves and is detected detection precision and can't obtain effective assurance, receives factors such as measuring tool is unset simultaneously, leads to measuring operation inefficiency, has the technical problem that the operation is wasted time and energy and the precision is poor.

generating a detection operation signal, measuring and acquiring sensing data according to the detection operation signal, processing the open gear sensing data to obtain open gear detection data, triggering a distance measuring sensor according to the detection operation signal, obtaining the distance between the other surface to be detected and the sensor through the distance measuring sensor, acquiring the open gear sensing data through the distance measuring sensor, and performing gain processing on the open gear sensing data to obtain the open gear detection data;
and displaying a single measurement result according to the sensing data, performing subsequent measurement according to the single measurement result, displaying the opening detection data in real time, receiving the sensing data and the opening measurement data, comparing the sensing data with a preset distance threshold value, judging whether the sensing data is qualified or not, and if not, triggering a retest function to detect again.
6. The method of claim 5, wherein generating the detection operation signal, measuring and acquiring the sensed data according to the detection operation signal, and processing the opening sensed data to obtain opening detection data comprises:
receiving the PLC measurement instruction information;
pressing a detection button according to the PLC measurement instruction information to generate a detection operation signal;
triggering a distance measuring sensor according to the detection operation signal;
the distance measuring sensor acquires the open gear sensing data, and the open gear sensing data is subjected to gain processing to obtain open gear detection data.
7. The method of claim 5, wherein displaying the single measurement based on the sensory data, performing subsequent measurements based on the single measurement, and displaying the opening detection data in real time comprises:
receiving the sensing data and the opening measurement data;
comparing the sensing data with a preset distance threshold value, and judging whether the sensing data is qualified;
if yes, displaying qualified prompt information;
if not, displaying unqualified prompt information, and triggering a retest function to detect again;
and processing the opening test data into display information, and displaying the opening test data according to the display information.
