Ningbo enterprise shield machine remote control escorts China's infrastructure construction

Recently, Ningbo Daily interviewed Tan Qiangsheng, Deputy General Manager of CBR. On June 18th, the front page of Ningbo Daily published an article titled 'Ningbo Enterprise Shield Machine Remote Control Escorts China's Infrastructure'. The article introduced CBR's insights into industry segmentation, the promotion plan for domestic substitution of shield machine remote control, and the development plan for continuous development and innovation. On the same day, the article was reprinted on the homepage>News>Economic Information of the Ningbo Municipal People's Government. In CBR's view, this is not only a recognition from the Ningbo government, but also a driving force and source for continuously inspiring CBR people to innovate and move forward. The following is the full text of the article:

Small, but not to be ignored - this is the evaluation of Tan Qiangsheng, Vice General Manager of Zhejiang CBR Electric Co., Ltd., on the intelligent control sub industry. A small remote control is an unavoidable node in the fields of lifting equipment, metallurgy, construction machinery, engineering machinery, etc. Once, we were firmly 'choked' by foreign companies on this, 'said Tan Qiangsheng.

Shield tunneling machine is a typical representative of high-end equipment and is known as the 'king of mechanical equipment'. Over the past decade, due to high technological levels and manufacturing difficulties, large and medium-sized domestic enterprises have often adopted imported equipment. The wireless control device technology of shield tunneling machines is controlled by a few German companies.

China has the title of 'infrastructure expert', and the core intellectual property rights of wireless control equipment for construction machinery must be firmly controlled in its own hands, 'said Tan Qiangsheng.

In May 2020, CBR Electric established a strategic partnership with China Railway Engineering Equipment Group Co., Ltd. and launched the research and development of wireless remote control devices for shield tunneling machine segment assembly machines, challenging the monopoly position of foreign companies in this field.

On the R&D team's schedule, the 'two-step' R&D plan is particularly clear.

Firstly, we need to achieve 100% domestic substitution in software, not only to overcome difficulties such as data interfaces, command systems, wireless communication protocols, but also to achieve plug and play with shield tunneling equipment and interoperability with other remote controllers, 'said Tan Qiangsheng.

The remote control is the 'brain' of the device, and the remote control itself also requires the 'strongest brain'. Every action reflected on the shield machine actually relies on data to present. It is actually very difficult to match the remote control with the machinery from '0', 'Tan Qiangsheng recalled the scene during the first experiment.' As soon as the remote control is operated, the equipment cannot move

So, the R&D personnel of the enterprise learned while doing, explored while thinking, analyzed data and adjusted code time and time again, finally making the shield machine go from being 'dumbfounded' to 'stumbling', and then to 'enjoying the smoothness' with every move. Nowadays, we have independent intellectual property rights for the code logic, on-site industrial control applications, technical protocols, spatial wireless scheduling, and automatic error correction of lost codes in remote controls, 'said Tan Qiangsheng.

After more than a year of design and development, the hardware of the wireless remote control device for the shield tunneling machine segment assembly machine has basically matured. At present, the product has successfully passed a series of tests such as electromagnetic pulse compatibility EMC, high altitude, high and low temperature, IP65, etc. conducted by China Saibao Laboratory. At the same time, some products have also been sold back to Europe for adaptability testing.

Regarding the last piece of the puzzle of domestic substitution - CPU, CBR Electric has also launched a 'chip replacement project' to concentrate efforts on overcoming difficulties and strive to achieve a 100% localization rate of the chips used by the end of this year, truly freeing domestic brands from constraints.

From scratch is innovation. After continuous design and development in the past two years, CBR Electric has achieved full coverage of wireless remote control devices in the shield tunneling machine industry, and will soon accompany domestic shield tunneling machines to 'go global'. At present, domestic shield tunneling machines have been accepted by foreign countries, and the remote controllers we produce have strong competitive strength in terms of price, comfort, flexibility and other operating experiences. Tan Qiangsheng said that after ten years of hard work, CBR Electric will be determined to safeguard China's infrastructure.
