Communication and control implementation scheme of "underwater remote control robot"

background

Deep sea operation equipment manufacturing industry

With the development and growth of my country's economy and science and technology, the exploitation and construction of marine energy, as the "blue granary", has gradually become an important cause. Deep-sea operation equipment has become an essential and key tool for marine energy exploitation, and its performance and reliability must be guaranteed. Therefore, the development of marine engineering equipment with better performance, safety, reliability, and durability has become an urgent problem to be solved in the deep-sea operation equipment manufacturing industry.

Trust our partners

Shanghai CRRC Esendy Offshore Equipment Co., Ltd. (SMD Shanghai) is a large enterprise focusing on equipment for marine engineering projects. Based on the strong deep-sea technical support of SMD UK and the profound technical background of its parent company CRRC in the field, it has industry competitive advantages in deep-sea robot control, deployment and recovery systems, and underwater system integration. Considering the stringent requirements of marine equipment for working temperature, humidity, protection level, and corrosion resistance, the company's ROV deployment and recovery system (ROV: remoly operated vehicle, unmanned remote submersible) was finally decided to use Hongke EX eX707 industrial control screen for implementation and control. This article will share this equipment application for everyone as a reference.

Specific usage scenarios

SMD Shanghai uses the eX707 industrial control screen and the supporting JMobile Studio configuration software to achieve data interaction and remote monitoring of ship equipment , ensuring the ship deck deployment and launching process. To facilitate on-site operation, the eX707 is installed in the control cabinet next to the equipment. Its main function is to control the entire set of deck equipment, ensuring the safe implementation of the underwater remote control robot from the deck to the sea surface and the launching process, that is, to realize the control of the entire machine deployment and recovery system.

In the control cabinet, the operating handles, buttons, etc. are connected to directly issue control commands to the equipment body. The industrial control screen communicates with the PLC to ensure that some command functions can be implemented through the soft buttons in the HMI visualization interface. With the powerful visualization function of JMobile Studio configuration software, on-site personnel can easily view the equipment operation and alarm status through the alarm and indicator screen in the industrial control screen , which greatly improves the work efficiency of on-site staff.

Why choose Hongke's industrial control screen?

During the process of communicating with SMD, we learned that in addition to the commonly used functions mentioned by the other party, such as definition, alarm triggering, recipe dump and restore, user permission setting, bilingual setting, etc., they also paid more attention to functions such as screenshot and buzzer . Due to the outdoor lighting in the shipbuilding industry, the screen will be strongly reflected when the on-site personnel take a direct shot, so the screenshot function is needed. The buzzer function is to notify and remind the on-site staff when the alarm is triggered.

What makes Hongke IoT industrial control screen eX707 different?

Compared with ordinary industrial control screens, the EXOR industrial control screen provided by Hongke has many features such as high protection, wider temperature, multiple certifications (CE, DNV-GL, ATEX, IECEx, UL, etc.), massive communication protocols, etc., and the warranty period is up to 5 years, which shows its excellent performance. The powerful configuration software JMobile Studio has built-in 2000+ modern style controls , and the drag-and-drop page configuration quickly helps users complete project development. Combined with exclusive functional controls such as trends and alarms, it helps users to realize project engineering data trend viewing, alarm notifications, user authority management, etc., to meet the functional needs of industry users, and the multi-language function also provides convenience for domestic and foreign engineers. The highly adjustable screen brightness (100% backlight adjustment) of Hongke eX707 meets the operating requirements of the shipbuilding industry in strong light and night environments, and has professional ship and explosion-proof certifications , etc.

In China, Hongke has in-depth cooperation with EXOR, and is committed to introducing industrial control screens such as the eSMART series, eX700 series, FB series for the food/pharmaceutical industry, and eX700G series for harsh outdoor environments into more suitable application scenarios.
