Description

Technical Field

[0001] The utility model belongs to the technical field of slag bag positioning systems, and in particular relates to a slag bag automatic transport flatbed vehicle positioning system. Background Art

[0002] With the rapid advancement of digital transformation in enterprises, the traditional observation method of the automatic transport flatbed truck for slag slag bags can no longer meet the requirements of data-driven production optimization control, reducing the difficulty of operation for operators, and ensuring the personal safety of operators. Usually, the flatbed truck for slag bags has three positioning points, and the corresponding operation is completed when it reaches the designated position. Due to the extremely high temperature of slag bags in pyrometallurgy, accurate positioning of slag bags is one of the key factors to ensure production safety. Therefore, real-time and accurate acquisition of the position data of the flatbed truck for slag bags is crucial for the transfer of metallurgical slag liquid.

[0003] At present, the traditional manual method is used to observe the position of the slag ladle flatbed truck during the process of production. During the operation, the personnel need to confirm the movement position of the flatbed truck through the reserved observation window and control the flatbed truck to reach the designated position. In the actual production process, the existing manual observation method of the slag ladle flatbed truck brings many shortcomings to the personnel operation and flatbed truck positioning. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned method of observing the position of the slag bag flatbed truck in the traditional manual way, the utility model proposes a slag bag automatic transport flatbed truck positioning system, which aims to solve the problems of small observation window, poor light and inconvenient observation; low accuracy of positioning of the flatbed truck controlled by manual observation; high temperature and dusty working environment on site, which is not conducive to the health of operators; low degree of digitization; high dependence on human experience and insufficient degree of standardized detection.

[0005] To this end, the utility model adopts the following technical solutions:

[0008] The analog signal output end of the laser rangefinder is connected to the input end of the data collector. The laser rangefinder is used to detect the real-time distance of the automatic slag bag transport flatbed truck and convert the distance information into a linear analog voltage signal output.

[0009] Furthermore, the data collector includes a voltage divider and an A / D analog-to-digital converter. The voltage divider is used to convert the output voltage of the laser rangefinder in proportion to meet the input effective range of the A / D converter. The A / D converter is used to convert the analog quantity of the voltage divider output signal into a digital quantity.

[0010] Furthermore, the driver includes a DC relay and a relay driving module. The relay driving module amplifies the power of the MCU microprocessor I / O output control signal to improve the load capacity of the I / O port and is used to drive the DC relay to be closed or disconnected. The DC relay is used to improve the node output driving capability.

[0011] Furthermore, the data display includes a digital tube display area and a strobe warning light. The digital tube display area is composed of a 4-digit 5-inch 8-digit digital tube, which is used to display the real-time position distance information of the slag bag flatbed truck. The strobe warning light is composed of yellow, green and red lights, which are used to give an alarm when the slag bag flatbed truck arrives at a predetermined position. The green light represents that the slag bag flatbed truck has arrived at the designated 1# position, the yellow light represents that the slag bag flatbed truck has arrived at the designated 2# position, and the red light represents that the slag bag flatbed truck has arrived at the designated 3# position.

[0012] Furthermore, the data transceiver includes an RS485 interface and a serial port. The RS485 interface is used for mutual communication with other devices, and the serial port is used for data interaction with the numerical display system.

[0013] The beneficial effects of the utility model are:

[0014] The online automatic identification system for the position of the flatbed truck for automatically transporting slag bags can realize functions such as real-time tracking of the moving position of the flatbed truck, fixed-point prompting, and position display. The utility model solves the application problems affected by factors such as high temperature and dust on site. The successful application of the online automatic identification system for the position of the flatbed truck for automatically transporting slag bags can provide production data support for the subsequent construction of the workshop production information platform, making the production organization of slag bag transfer more efficient, emergency response more timely, and the visual interface more friendly.

The data display can intuitively display the position information of the slag bag flatbed trolley, and a flashing warning light will be displayed when it reaches the predetermined position. The system realizes the digitization of the movement position of the automatic transport flatbed trolley for slag slag bags, automated detection, and intelligent analysis, reduces the uncertainty of human observation, and has accurate and reliable positioning and high detection efficiency, which is worthy of promotion and application.

The 5-inch 4-digit high-brightness digital tube 10 is connected to the interface of the controller 2 to display the relative distance value between the transport flatbed and the laser detector 3 in real time to realize the automatic positioning of the slag bag transport flatbed.
