Electronavigation continues to cultivate new models and new formats
Beidou +, from the edge of the sky to the side
On December 13, the staff of CETC Satellite Navigation Operation Service exchanged views on the technical upgrade of Beidou image transmission terminals. Courtesy of Electrical Navigation.
During the autumn harvest, the harvester equipped with the Beidou system transmits back the operation trajectory and duration in real time, allowing farmers to accurately monitor the progress of the operation.
On the highway, trucks equipped with Beidou system can transmit information such as location and speed back in real time to improve the turnover efficiency of the freight logistics system.
Beidou is on the horizon, and service is around. The Beidou system carried on agricultural machinery and trucks is partly from the CETC satellite navigation operation service in Shijiazhuang***hereinafter referred to as "CETC Navigation").
At 10 o'clock on December 6th, when the reporter came to the customer service department of Dianke Navigation, the staff was using the Yuntu big data service platform to generate reports. "These reports are the actual data of this year's autumn harvest and autumn planting of agricultural machinery operations, such as operation time, operation area, etc., which will be sent to customers for reference. He Xiaoqi of the customer service department said.
What role can data play?Why do customers use this platform?In order to better answer the reporter's questions, He Xiaoqi contacted Tang Qinglei, the person in charge of the Handan Agricultural Machinery Service Center.
At the time of the slack, Tang Qinglei was maintaining agricultural machinery. He turned the lens to the rows of agricultural machinery in the yard and said that there are more than 100 agricultural machinery such as harvesters and seeders in the service center, all of which are equipped with Beidou agricultural machinery operation monitoring terminals, and the cab is equipped with a display screen that can display operation information in real time.
The relevant data is directly connected to the Yuntu big data service platform. On the platform, you can see the location of agricultural machinery, operation track, operation area and other information, which makes scheduling and management of agricultural machinery more convenient and improves operation efficiency by at least 20%. Tang Qinglei said that when sowing in the field, thanks to accurate positioning, the problems of unstraight sowing and uneven plant spacing are solved, and the field sowing is completed with high efficiency, high precision and high quality.
The data is intuitive, and farmers are more trusted. Since the Beidou system was used in 2016, the cultivated land managed by the Handan Agricultural Machinery Service Center has grown from more than 1,000 mu to 240,000 mu, and the income has increased from 200,000 yuan to more than 3 million yuan.
With the blessing of Beidou, agricultural production is like having an "eye in the sky", and traditional agriculture is upgraded to smart agriculture.
Such agricultural machinery terminals, electrical navigation has been iterated several times, applied in 160 counties (cities, districts) across the country, with a market share of more than 50% in Hebei Province.
What does this depend on?
Keep innovating!Many people can't imagine that this terminal can calculate the working area just by monitoring the position of agricultural machinery. Li Bo, director of the R&D department, took out a small black equipment and said that this is their latest independent research and development of the Beidou agricultural machinery operation monitoring terminal, which has realized the national production substitution, which can not only save costs but also improve efficiency.
In the past, in order to calculate the operating area of agricultural machinery, in addition to Beidou navigation and positioning technology, a variety of supporting sensors were needed to assist in calculation. Many modules in the equipment also rely on imports.
Can we break through the existing technology and develop a high-performance, low-cost multi-functional agricultural machinery terminal that can be replaced by national production?
At the beginning of this year, after the feasibility study, the R&D team immediately started to develop.
No ideas, brainstorming;No experience, slowly groping. "The hardest part is how to achieve both performance and cost benefits. Li Bo said that the team held its breath and had to overcome the difficulties.
Experiment after experiment, failure after failure. Summarize and adjust again and again, and make progress again and again.
More than two months later, the Beidou agricultural machinery operation monitoring terminal that was replaced by national production was successfully developed
The new terminal has been lowered, with more functions and more accurate calculations. "This year's autumn harvest and autumn planting, some agricultural machinery has used new terminals, and the market response is very good. Li Bo said that they have also developed new technologies and new products such as Beidou cameras and precision seeding monitoring terminals this year, and are expected to apply for 8 patents next year.
Deeply cultivating the Beidou system, CETC Navigation continues to break through core technologies, accelerate the cultivation of "Beidou +" new models and new formats, and promote the formation of new quality productivity.
In the field of transportation, based on Beidou + intelligent ** monitoring technology, CETC Navigation has developed the Beidou active safety cloud platform and terminal, so that operating enterprises can understand the location, speed and other information of vehicles at any time, intelligently plan routes for vehicles, and improve the efficiency of cargo circulation. The platform can also identify and alert unsafe driving behaviors such as drowsy driving and calling**.
Using the Beidou active safety cloud platform, Du Antian, deputy general manager of Anxing Special Cargo Transportation in Cangzhou City, has an intuitive feeling that the drivers' driving behavior is more standardized, and the accident rate is also greatly reduced.
Short message communication is also a direction for the expansion of electrical navigation. The so-called short message communication refers to the two-way information transmission between the Beidou ground terminal and the Beidou satellite and the Beidou ground monitoring station through satellite signals. Especially in areas that cannot be covered by mobile communications and the Internet, short message communication can play a greater role.
Having made breakthroughs in data compression, massive data processing, low-power terminal design and other technologies, CETC has formed a series of short message communication products and solutions, which have been applied in water conservancy, petrochemical, electric power, emergency and other industries.
Enhance competitiveness with innovation. In Dianke Navigation, the annual R&D investment accounts for more than 10% of the operating income, more than half of the employees are R&D personnel, more than 50 research projects, 37 patents, and 97 software copyrights.
In ancient times, people used the Big Dipper to distinguish directions and identify the four seasons.
Today, China's self-developed Beidou satellite navigation system serves the world, and the large-scale application of Beidou has entered a critical stage of marketization, industrialization and international development.
At present, it is not only a critical period for the large-scale application of Beidou, but also an opportunity period for the development of the entire Beidou industry. Yang Kaiwei, general manager of CETC Navigation, said that they will seize this development opportunity, continue to break through the key core technologies of the industry, promote the cross-integration of Beidou and digital technology, promote the deep integration of Beidou and more industries, and let the Beidou application far away in the world be around people.
