Control device for vehicles for rail way, marine, and high place

We have experience in development of control devices for railway vehicles (diesel railcars), marine vehicles, and vehicles for high place (orchards). We can develop those controllers.
Not only quality control, you need to meet requirements for strict environment-resistant performance for this type of controllers. Expertise in circuit design is necessary.

Embedded Software

Embedded system is employed to operate machinery ranging from an industrial machine to home appliances, and a software controlling embedded system is called embedded software or microcomputer software.

PC takes on operation for multi-purposes. On the other hand, embedded system is optimized for a certain function. Embedded system performs more efficient than a PC when employed for a single intended purpose.

Developing an embedded system requires advanced expertise. When building an embedded system, a software and hardware are developed concurrently. Usable resources (ROM, RAM, and CPU) for an embedded system are limited for a small vacancy. Failures are likely to happen in both a software and hardware and discerning which of them is responsible is not easy task to be done. Therefore, an embedded system developper must have deep understanding in both of the two distinctive fields.
