On March 10, the Long March 3B carrier rocket ignited and took off from Xichang Satellite Launch Center, and the Communication Technology Test Satellite XV entered the scheduled orbit smoothly. (hereinafter referred to as "Gohua Technology") for this launch supporting a variety of self-developed sensors, supporting the high reliability and consistency of the product to help launch the mission to achieve a complete success. Sensors are equivalent to human sensory organs, such as the five senses and skin, with high technological content, many application scenarios, and wide development prospects, reflecting the characteristics of "specialization, specialization and innovation". Founded in 2000, Gao Hua Technology is a national specialized, special new "small giant" enterprise, mainly engaged in the research and development, design, production and sales of high-reliability sensors and sensing network systems, and has always been market-driven development, with a strong R & D team and sustained technological innovation, to achieve the core technology independently controllable.
Every step forward is accompanied by a technological breakthrough.
"The multiple sensors and sensing network system that we support for 'Changsanb' are responsible for measuring the temperature, humidity, pressure, vibration, heat flow and other signals within the multi-system, and transmitting the various data sensed to the monitoring center through telemetry to achieve real-time monitoring of key parameters on the arrow and in the fairing, to Ensure that the load environment meets the requirements." Li Weiping, Chairman of Gohua Technology, said proudly.
Up to now, the sensor-related products of Gohua Technology have been widely used in aerospace, aviation, high-speed railroad and railway, high-end equipment and other industries, and have participated in and successfully completed the manned spaceflight project, the moon project, the Beidou project, the construction of the space station and other key projects supporting the task. Look up to the stars and keep your feet on the ground. Li Weiping recalled the enterprise for more than 20 years when the road, said with emotion: "the company every step forward, accompanied by a technological breakthrough, scientific and technological innovation throughout." Time back to 2000, China's rapid development of the communications industry. Li Weiping keenly aware that, with the high-end equipment to automation, information technology and intelligent transformation and development, their demand for sensors will be greatly enhanced, so with entrepreneurial dreams to Nanjing, with a few partners founded Gao Hua technology, headlong into the sensor research and development. However, the sensor research and development is not so easy. It is a fusion of multiple technologies, including chip packaging, circuitry, structure, scene matching and other technologies. "At that time, the scale was small, the conditions were simple, and each team member not only had to do R & D, but also had to do the product, management, marketing, and even took turns in the rented house to buy food at the grocery store as a chef." Li Weiping said, but the start-up team continued to conduct in-depth research on every task, never let go of the problems encountered, and met customer needs through technological innovation, thus bringing about market breakthroughs. In 2005, the construction of high-speed rail "Harmony" using sensors and other imported electrical and electronic control equipment is incompatible with domestic conditions, the urgent need to achieve a breakthrough in localization. "When we found Gohua Technology, we took over this task without hesitation, and spent two years to overcome a series of technical problems, and realized the localization of sensor substitution." Li Weiping said that this breakthrough also allowed them to open up a huge market in the field of high-speed rail. The same is true for entering the aerospace field. Follow the rocket lift-off sensors, there is a called pulsation pressure sensor, used to monitor the rocket operation process of gas fluctuations, in order to accurately grasp the rocket operating state, with a small pressure range, fast response, high reliability, small size, integration and other requirements. "Only by gnawing down this piece of hard bone, we can enter a completely new field!" With this strength, Gohua's R&D team of more than 20 people at that time, who were sleepless and hungry in the laboratory, went all out to successfully solve these technical "choke points" and meet the standard requirements of the aerospace field.
Going all out to show corporate commitment in science and technology innovation
Step into the hall on the first floor of the Gao Hua Science and Technology Office Building, several vertical model rockets are very realistic, a state of impending launch, fully demonstrated the company in recent years with China's space industry "unbreakable ties".
The third floor is the company's R & D center, a group of R & D personnel are busy in their respective positions, the same floor there is a laboratory, to facilitate their innovative inspiration in a timely manner.
"Sensors in the aerospace field are disposable and require powerful functions, while sensors used in the aviation field have very high reliability requirements." Qin Lei, deputy director of the R & D center, told reporters that they will use simulation software at the beginning of the design simulation verification, and strict screening of manufacturing materials, and then in the laboratory "a thousand hammers".
The technical requirements are high and the development cycle is long. "For example, the pulsation pressure sensor has to undergo tens of thousands of pulsation impacts and pass anti-interference tests in the electromagnetic compatibility laboratory to ensure that the reliability meets the design and use requirements." Qin Lei said.
Hydraulic system, engine, cockpit ...... There are hundreds and thousands of different sensors spread all over the important parts of an airplane, and now, with years of technology accumulation, Gohua Technology is able to provide a full chain of solutions.
This comes from the persistent and innovative research and development. Currently, Gohua Technology has a total of nearly 500 employees, with R&D personnel accounting for more than 30%, as well as dozens of professors from key universities as guest experts.
"The company's annual R&D investment accounts for about 15% of revenue, and it has invested in more than 1,000 sets of various production, R&D and testing equipment, including automated production/calibration systems, high-voltage impulse test benches, vibration acceleration test systems, thermal vacuum test chambers, X-ray/CT testing, electron scanning electron microscopes, EMC EMC test systems, far-field antennas darkroom, etc., totaling more than 100 million yuan of investment." Li Weiping introduced.
Gain development in science and technology innovation, but also in scientific and technological innovation to show corporate responsibility. Whenever there is a need for national key engineering projects, Gohua Science and Technology will go all out and concentrate the best resources of the whole company to "roll up the sleeves and work hard".
Sensors are connected by cables, but there are problems such as high load, complex assembly, etc. Breakthroughs in wireless sensor network systems have become a "national mission".
"No domestic company has yet tackled the wireless sensing network system on the rocket, which is very different from the wireless sensing technology popularized on the ground, and is extremely difficult to research and develop in the face of the complex electromagnetic environment, space environment and so on." Li Weiping said.
This project started its research and development in 2014, and after more than three years, it finally achieved a breakthrough in 2017 and successfully flew on a rocket in May of the following year. Gohua Technology also became the first domestic enterprise to master the wireless sensor network system.
Practicing the best skills and striving to be the leader of the industry's development
"These universities have a lot of research in the technical achievements, we are to transform these innovations into the ground, industrialization and development." In the interview, Li Weiping phone calls, has been discussing with the company's staff "production, research and development" of the topic. Science and technology casting "high-precision" barriers, the performance of the "high growth" curve, the industry continues to develop "high boom" trend... ...After more than 20 years of development, Gohua Technology has fully demonstrated its "three high" characteristics, continuously promoted the development of the industry, and won wide recognition from customers and good reputation in the market. On April 18, 2023, Gohua Technology was successfully listed on the Science and Technology Board of the Stock Exchange. Capital boost for the enterprise to bring great opportunities for development, but also face great challenges, since the listing, Li Weiping is busier than before, more time to run around, "before the listing, the company completed the 'from 0 to 1' breakthrough; after the listing, the company has to realize the 'from 1 to N' breakthrough. 'from 1 to N' butterfly."
In recent years, as commercial space and other national emerging industries and future industries are hot, Gohua Technology has also accelerated the layout and entered into new fields such as commercial space, low-altitude economy, robotics and intelligent manufacturing, etc. Gohua Technology has been firmly taking the road of high-end, intelligent, green and integration, and has been deeply empowered with the development of new-quality productivity.
"Technological innovation is our specialty and advantage, and at present, a number of head enterprises in the domestic commercial spaceflight field have in-depth cooperation with Gohua Technology." Li Weiping told reporters that commercial spaceflight is a large-scale launch, high-density launch, in the case of ensuring stability and other technical requirements, the cost control also put forward higher requirements. In order to cope with the fierce market competition, Gohua Technology set up a wholly-owned subsidiary of Suzhou Purple Core Microelectronics Co., Ltd. to focus on the field of self-research chip, set up a wholly-owned subsidiary of Nanjing Gohua Sensing Technology Co., Ltd. and Beijing Gaoxing Huachen Sensing Technology Co., Ltd. to target commercial spaceflight, low-altitude economy and other areas around the sensor network system of technology research and development and market development. With the rapid development of artificial intelligence and other new-generation information technology, will drive more demand for the sensor industry, Gohua science and technology has never stopped exploring the footsteps. Journey of thousands of miles, the original intention remains unchanged. "We will aim at cutting-edge technology areas to increase R & D investment, practicing mastery, to meet market demand with more high-quality products, and strive to be the front-runner in the development of the industry." Li Weiping said.
