The invention discloses a webpage updating request generation method and apparatus. The method comprises the steps of obtaining request parameters used for performing asynchronous updating on a webpage; generating an initial request used for requesting to asynchronously update the webpage by utilizing the request parameters; detecting parameter types of the request parameters; and writing the parameter types of the request parameters into fields used for representing the parameter types of the request parameters in the initial request, and obtaining an updating request. According to the method and the apparatus, the technical problem of high error rate of the parameter types in the prior art is solved.

The invention discloses a method for recording drilling depth and hammering times and a drilling device. The method is to install a hammering sensor on a drilling rod, and a heavy hammer Each When the hammer sensor is hit once, the counter set on the top of the drill rod will record once; a group of infrared emitters are installed at intervals on the drill rod, and when the probe at the bottom of the drill rod enters the ground and reaches an interval depth under the hammer, the set The infrared alarm on the top of the drill rod immediately alarms because it cannot receive the signal from the infrared emitter, and reminds the operator to record the number of hammer strikes at the penetration depth in time through the alarm sound; it avoids manually looking at the scale and counting the number of strikes Insufficient errors are prone to occur. The present invention is novel in concept, small in size, light in weight, compact in structure, convenient in transportation, fast in machine transfer, safe and reliable, convenient in maintenance, simple in operation and easy to master.

The embodiment of the invention provides a method and device for detecting subtitle definition. The method comprises the steps of obtaining a video file of to-be-identified subtitles, carrying out analysis to obtain a picture of each frame in the video file, and storing the picture of each frame to a queue corresponding to the video file; identifying the total character string length and the totalcharacter number in each picture through an OCR algorithm and calculating a first ratio of the total character string length and the total character number in each picture; comparing each first ratiowith a preset ratio threshold and determining a weight value of each first ratio; and determining the number of the weight values smaller than the preset ratio threshold in the weight values of the first ratios, calculating a second ratio of the number and the total number of the second ratios, and judging whether a subtitle display effect of the video file is qualified or not according to the calculated second ratio. Through application of the method and the device, the definition degree of the subtitles in the video file can be detected rapidly and conveniently.

The invention relates to a gear M-value rapid diameter measuring jaw linkage mechanism which is characterized by comprising a base plate, wherein a clamp support is installed at one end of the base plate and is provided with a clamp; a first hole of a first sliding block is internally provided with a summation and difference rod; the first sliding block is provided with a first sliding groove installation moving measuring rod device; a first pressing spring fixed seat is provided with a first spring device; a second guide rail is slidingly connected with a second sliding block; the second sliding block is provided with a second sliding groove installation fixed measuring rod device; second pressing spring fixed seats are installed on the base plate; a second spring device is arranged between the second pressing spring fixed seats; the second sliding block is threadedly connected with a clipping body; the clipping body is provided with a measuring device; and a connecting rod device is installed at the middle of the base plate. The gear M-value rapid diameter measuring jaw linkage mechanism provided by the invention is simple to operate, and is intuitive in reading, data is accurate, and the situation that the matched measurement of a clipping ruler and a measuring ball causes error easily is prevented; and the manufacturing cost is low, and the enterprise production operation cost can be lowered.

The present invention aims to provide a management system for hot work tickets, which can get rid of the use of paper hot work tickets, and at the same time realize the management of equipment and personnel in hot work tickets, including: an operation system for The hot work plan creates a hot work ticket, and conducts SHE audit on the hot work ticket; the mobile terminal searches for the hot work content that matches the hot work plan, and selects the relevant information of the matching hot work content to enter into the hot work Work ticket, the mobile terminal enters the hot work information in the hot work process into the hot work ticket in real time; the mobile terminal uploads the work ticket entered with the hot work information to the management and control platform; the positioning card is used for the dynamic For the positioning of personnel and equipment during fire operations, the positioning card communicates with the management and control platform to report the positioning information of personnel and equipment. When the personnel or equipment carrying the positioning card meets the alarm trigger conditions, the management and control platform sends out an alarm.

The invention relates to a method for accurately positioning the defects of a material during ultrasonic detection. The method comprises the following steps: firstly, establishing a reference position on a water-immersion based ultrasonic C scanning detection system, and calibrating the coordinate of the reference position in an ultrasonic probe acoustic-beam scanning position coordinate system; then putting the material to be detected in the reference position of the detection system through a positioning reference plane processed on the material to be detected, and carrying out ultrasonic C scanning detection, determining the accurate coordinates of all the defects in the ultrasonic probe acoustic-beam scanning position coordinate system on an ultrasonic C scanned image by using the defect searching function of the water-immersion based ultrasonic C scanning detection system, and deducting the coordinates of the detects on the ultrasonic C scanned image from the coordinate of the reference position on the water-immersion based ultrasonic C scanning detection system to obtain the accurate coordinates of the defects on the positioning reference plane processed on the material to be detected; and finally combining the coordinates of the defects on the positioning reference plane processed on the material to be detected with the depths of the defects read by an ultrasonic defect detection unit on the ultrasonic detection surface of the material to be detected to form the three-dimensional spacial position coordinates of the defects in the material to be detected.

The invention discloses a software testing method, system and testing platform, wherein the method includes the following steps: automatically generating a test case analysis and execution program source file according to the software to be tested, and compiling the test case analysis and execution program source file to generate an executable file; burn the executable file into the operating platform of the software under test; send the preset test case corresponding to the software under test to the executable file, and execute the test case by the executable file to test the software under test; Receive and save the execution result after the executable file executes the test case. By automatically generating test case analysis and execution program source files according to the software under test, it is no longer necessary for testers to manually write source files, which effectively reduces the workload of testing and reduces the difficulty of testing. Ultimately, the traditional software module interface testing method has certain limitations and low efficiency.
