It needs to be explained that the open type straight wind tunnel test section has strong operability, provides a larger space for automatic modification, and the mechanical arm is easy to extend into the test section to grab and install the sensor; however, on the premise of not changing the flow field quality of the test section, the test section of the closed loop wind tunnel is only provided with a movable mechanism provided with a sliding door, and the mechanical arm cannot directly extend into the test section to clamp the sensor in a narrow space. Therefore, the realization method for realizing the automatic verification of the wind speed of the closed loop wind tunnel by using the mechanical arm is different from that of the open straight wind tunnel, so that the transformation of the closed loop wind tunnel becomes a bottleneck difficult problem, and the automatic clamping cannot be realized only by simply introducing the mechanical arm.
Supplementary explanation:
the system design idea is as follows: the 70m/s loop wind tunnel test section is divided into a first test section (800mm x 800mm) and a second test section (1300mm x 1300mm), a 0.6m2 mechanical arm 3 activity area and a 2m2 annular transmission device area are respectively arranged below the first test section, the installation position of the mechanical arm 3 is planned in the mechanical arm 3 work area, the three-dimensional coordinates of each point position when the mechanical arm 3 acts are established according to the position of field equipment, and Solidworks simulation software is used for modeling in the design process, so that the problems of intelligent identification, starting position identification, ending position positioning, optimal motion path planning of the mechanical arm 3 and the like of the wind speed sensor 7 are mainly solved; the feeding and the discharging of the sensors are realized by adopting a mode of rolling and transporting the wind speed sensors 7 by the annular conveying belt, and the detection quantity of each batch of the wind speed sensors 7 is not less than 8.
And (3) verification software development: the software design flow of the 70m/s loop wind tunnel intelligent verification system realizes the manual verification function by defining a data interaction interface, developing a sensor state monitoring function, developing the functions of detecting the set point, setting the number of the sensors to be detected and the like. The development process mainly comprises the following steps: firstly, defining a data interface of a design system, enabling the system to receive action instructions issued by a metering service platform, and feeding back verification data to a related software platform, so as to realize seamless connection of the intelligent temperature verification system and the metering service platform; the upper computer software development comprises a sensor state monitoring module and a testing function module, and state judgment of the sensor on the endless conveyor belt, such as detection, inspected or verification, is realized; the test function module refers to the functions that under the test state, a verification worker can set verification points, the number of sensors to be detected and the like in the test process independently; and finally, developing a manual verification function of verification software, namely, manually completing verification work by a verification worker in a state that the mechanical arm 3 is separated from the mechanical arm 3 or the mechanical arm 3 fails in an automatic verification process.
And developing system control software according to relevant verification rules and a communication protocol of the existing wind speed verification standard device and the fan equipment, and controlling the whole system to finish verification tasks. And the related verification data is butted with the unified database and is backed up locally, and a verification certificate is automatically generated by calling a related data table. If the network is abnormal, the software can call the local database to automatically generate a verification certificate. The control software has a mode for a verification person to customize a test flow independently, and mainly comprises the functions of customizing the numerical value and sequence of the verification points, customizing the quantity of the sensors to be detected and the like in the test mode.
In fact, the wind tunnel control program and the program controlled by the mechanical arm 3 operate independently when executing various functions and actions, a data interface is designed for the two types of independent interfaces in the traditional software development mode, and once a software system fails, a large number of source programs are combined to find error codes, so that the software maintenance cost is increased. The system integration method of the project adopts an interactive communication method and is combined with a traditional data interface. The mechanical arm 3 part of software instructions comprise functional modules such as moving, grabbing, waiting, scram and conveyor belt moving, the wind speed verification part of software instructions comprises functional modules such as a verification point setting, fan rotating speed control, stable state judgment, qualification judgment and certificate generation, in order to ensure that the two functional modules can operate in a cross mode and can be positioned and removed quickly when a fault occurs, interaction commands which can be recognized by the two functional modules can be generated after the design and execution of each functional module are finished, and the subsequent modules start to act after receiving the interaction command of the previous module.
