Embedded digital hard disk recorders (DVR) what electronic components
DVR electronic circuit is mainly composed of digital circuits, the need for thousands of electronic original, there are ordinary chip resistors, capacitors, inductors, beads, digital logic chip, video codec chip, the system master CPU, Memory chips, flash memory, analog-to-digital conversion chip, power regulator chip, network chip, hard drive chip, reset chip, ordinary op amp chip, etc., too much. In addition there are some connectors, connectors and so on. And then go to PCB factory to do multi-layer PCB board. So what the original, the key is to see what you plan, when the program is determined, the original basically also determined.
In addition to the shell, packaging materials, wire, accessories, etc. constitute the DVR hardware architecture. This is not the most difficult, rare is that you must have a very professional software team, which includes the bottom of the drive, kernel, AP, application and so on the preparation of the program, there are similar to intelligent algorithms such as unpredictable The stuff should be put into. Not a few dozen people of the development team is not independent research and development, up to buy someone else's board shell only. Of course, you are a net worth of the boss and another matter.
First of all your question so that I can not laugh, you even DVR architecture are not clear, but also their own DVR? DVR is divided into hardware and software two parts, so to speak, just like a computer, installed after the machine also installed operating system. DVR development process roughly under: research market, to determine what the development of the product ------ selected the most appropriate development platform, which is the chip manufacturers which program -------- PCB layout, Software development at the same time -------- hardware and software testing and modification ------- trial production -------- and then modify --------- production.
