Two safe systems
MH Intelligent Safety provides its customers with safe profiles and safe sensor technology carefully combined for precisely coordinated interaction in all details – in materials, design, engineering, control and electronics.
In the final analysis, door safety systems in buses and rail vehicles consist of two interwoven systems: the rubber profiles and the integrated safety sensors with control elements.
Both systems must first meet the highest standards independently and then be perfectly harmonized with each other. The systems of MH Intelligent Safety fulfill these prerequisites to deliver the highest levels of safety and comfort. In close coordination with customers, practical solutions are developed from prototype to serial production.
The rubber profiles made of the materials EPDM and silicone in more than 400 special material formulations display high chemical and thermal resistance as well as outstanding mechanical stability and durability. They protect and cushion and seal. The profiles are resistant against heat, cold and UV radiation; they are water repellent, highly elastic and flame retardant. An optimal connection between metal and rubber parts is obtained with the pre-treatment of metal before vulcanizing the rubber.
Decades of experience are applied to each new project. With its compact, space-saving construction that makes optimal use of available room, the design is ideal for customers and passengers. And the sophisticated engineering ensures precise and exacting functionality.
The control and electronic elements ensure that the sensors concealed in the profiles react with exactly the desired level of sensitivity on every occasion.
The electronic control unit monitors the operation of the door and via the rubber profile registers if a person or object is caught as it is closing. The closing action is stopped via the reversal of the motor current and the door is opened automatically. The Gap Detection System (GDS) registers the presence of even very thin objects. And if the door is already closed, it sends a signal to the driver or opens the door automatically, according to the settings determined by the transport company operator. On request, the electronic control of the system can be set to be freely programmable (HEDCU) so that it can be individually defined whether – for example – the door should open completely or partly and also how many times.
