The CIN trains its sailors in hydraulics thanks to scalable façade benches

THE CONTEXT

Our double-face didactic benches are fully modular and scalable. They are suitable for all training types irrespective of the sector of activity. They give teachers the possibility to adapt their classes very simply.

We have already produced 2 hydraulic didactic benches in the naval sector for ENSM, the French maritime college. These benches were designed and adapted to match the teachers’ and trainers’ hands-on exercises.

The ID System design team initially developed a hydraulic didactic bench called BHI4 v2 (the 2nd version of this bench) to suit a large number of advanced technical training courses.

The CIN in Saint-Mandrier trains sailors on various cycles in the maintenance of on-board hydraulic installations. Students must understand all the workings of hydraulics (On/Off, proportional, open or closed loop).

CUSTOMER DEMAND

The arrival of highly automated new generation frigates calls for implementation of a platform for training in electro-hydraulic servo systems.

This platform is intended for training and certifying situation simulation exercises forstudents of 3 different levels.

The 3 class levels targeted are:

  1. 1st Level in Maintenance of Industrial Equipment (MEI) for the Technical Aptitude Certificate (Brevet d’Aptitude Technique: BAT) classes,
  2. Professional High School level in Maintenance of Industrial Equipment(MEI) for the Higher Certificate (Brevet Supérieur: BS) classes,
  3. Professional degree for higher certificate classes in the hydraulic sector.

This school, famous in France, had a number of requirements:

  • It had to be both simple and fun to use in order to be suitable for the various training channels: hydraulics, automation, mechanics and electricity.
  • It was essential to implement procedures and hands-on exercises specific to this type of training to ensure that the students’ learning process was as efficient as possible. Indeed, in the navy the teaching profession changes every 3 years.

THE ID SYSTEM DIDACTIC SOLUTION

To meet all these criteria, we have developed a customised bench compatible with today’s technologies, using technical and specific materials including a logic module andOn/Off and proportional valve components, with its digital control card.

Our design team has created the entire programming for the bench and the PLC. It has also devised a complete step-by-step procedure as well as 23 customised pedagogical hands-on exercises dedicated to the 3 classes mentioned above.

These hands-on exercises suggested are designed to understand or access different skills levels according to pedagogical and professional aims. The subjects tackled in our exercises tend towards the following technologies: hydraulic, electro-hydraulic, proportional hydraulic, programmable logic controllers, sensors, electrical notions and electrical actuators, mechatronics.

The aim was also to propose a common bench that could be used both during hydraulic and electricity classes. In actual fact, the bench is equipped with hydraulic, electrical and automatic servo systems. As classes complete one another, students attend them and train on the same pedagogical equipment.

There are many advantages: time saving for programming during the classes and advanced cross-sector pedagogical usage. Consequently, we have provided all the pre-registered programs for configuration of each proportional component in open and closed loop as well as the multiple PLC programs required for proper training of students.

The ID System team started up and took control of the hydraulic didactic bench for a few days to ensure that the equipment met the trainers’ expectations and that they could carry out their exercises properly in the classroom.

We would like to thank the CIN teams, Mr COLIN and Mr COLONA, for their participation in preparing the specification sheet for this bench and for the many exchanges in the creation of customised hands-on exercises.
