Laser scanners help Alma transport vehicles to locate and prevent collisions

Application in the transportation task of Atacama desert with severe environment: located in Atacama Desert in Chile with an altitude of more than 5000m, two special transport vehicles weighing 130 tons are responsible for transporting 66 radio wave telescopes produced by Scheuerle company during the important strategic opportunity period of development to their scheduled locations. The LMS221 outdoor laser scanner of sick assists these transportation vehicles in positioning and preventing collisions between vehicles

these two huge special transport vehicles are 20 meters long, 10 meters wide and 6 meters high, with a total weight of 250 metric tons. They were ordered by the European Observatory ESO, which is committed to astronomical academic research in the southern hemisphere, and the radio telescope is designated for use by the Alma project. The reason why the European Southern Observatory will work together with North America, East Asia and Chile in Atacama desert is that its geographical location is in a dry place, which is a very suitable place on earth for studying the universe

alma- movable array antenna creates a research method

alma stands for "Atacama large miller/sub is located in Atacama Desert, Chile, with an altitude of more than 5000m. Two special transport vehicles weighing 130 tons are responsible for transporting 66 radio telescopes produced by Scheuerle company to their scheduled location. The LMS221 outdoor laser scanner of sick assists these transport vehicles in positioning and preventing vehicle to vehicle collisions -- millimeter array". There are about 66 radio telescopes in this area, each of which can move individually and carry out research work independently. By 2012, each of these radio wave telescopes with a diameter of about 8 meters to 12 meters will be used to observe the remotest, coldest and darkest depths of the universe, with a resolution 10 times better than that of the Hubble telescope. Alma features that each radio telescope can move freely, forming the largest array antenna in the world. According to different research tasks, these telescopes, each of which is about 130 metric tons, can be arranged in a straight line and online, and are spread on the basis of concrete covering an area of about 225km on average. The large truck manufactured by Scheuerle company is responsible for moving these radio telescopes so that they can be arranged into a huge radio telescope network

atacama desert puts forward more stringent requirements for large-scale trucks. Chinese enterprises have the talent to produce their own plastic extrusion mechanical vehicles and sensing technology.

in winter when the temperature is as low as – 50 ° C and summer when the temperature is as high as 50 ° C, the dual diesel engine driven pendulum experimental machine generally has three force measuring ranges, 1360 horsepower is reduced to only 820 horsepower under the hypoxic atmosphere, On dusty roads and paths and radiation from space: these factors make it necessary to consider the use of special materials and components when building this special vehicle. Mr. Andreas Kohler, deputy manager of Scheuerle company, confirmed that "many parts that can be used before cannot be used in the plan of transporting radio wave telescopes this time. Because of this special condition, these parts must be slightly modified". The first task of these two special vehicles is to transport the radio telescope from the camp with an altitude of 2900 meters to the observatory on the 5000 meter plateau through the gravel road with a slope of 10% and a length of 28 kilometers, and then start the assembly. Starting in 2012, they will undertake the task of mobile radio telescope array antenna

sick outdoor LMS221 laser scanner adapts to the severe working environment

in order to meet these two demanding tasks, a total of four specifications of LMS221 laser measurement system are installed on the vehicle to protect the vehicle and radio telescope from collision. In addition, it can also assist in the precise positioning of the vehicle when carrying the antenna and assist in the sensitivity adjustment of elevator tilt. When the elevator rises, the vehicle will support the telescope, LMS221 laser measurement system can not only monitor the edge of the device as the name suggests, but also monitor the inclined area between the elevators on both sides. If a laser scanner detects the long-range radio telescope in front of it, its position needs to be corrected. If such a signal does not appear, the driver can also rely on the correct positioning provided by the LMS221 laser measurement system to assist in the installation of the antenna. The use of laser measurement system to monitor outdoor vehicles can ensure that the vehicle will not collide with other objects when moving in the operation area. Therefore, since 2012, through scientific management and scheduling, LMS221 laser measurement system has flexibly connected each movable Alma remote radio telescope and looked into the infinite space. The application of sick's laser measurement system has made great contributions to ensuring the success of scientific research
