– Introduction – What is development / design method

I will describe from my own knowledge and my own point of view. These contents are not the best way for all of this. There are various ways according to the situation. Moreover, there may be contents which stick to because they are looking at from their own point of view. I would like to think about a better method and I would like you to tell me if there is any problem.

Electric design 3 How to select power supply and circuit breaker unexpectedly not known

電源と遮断器選定

Do not know as it is known, how to select power supply and circuit breaker Selection of power supply is the foundation of equipment and equipment. Depending on this selection, the countries, areas of use, and methods of use are largely restricted. Therefore, let’s think first. The power supply here is a low voltage (AC […]

Electrical design 2 Concept of safety category for maintaining functions

Concept of safety category for maintaining functions Safety categories are named “safe”, so it tends to be confused with “safety”, but it is not. Safe Name of robustness / tolerance level that you can maintain function . The safety category is the degree of “strength of maintenance” of “safety function”. Therefore, the safety function (safety) […]

Flow of development

Flow of development ~ Development process of system and flow of process ~

開発の流れ

Development flow – System development process and process flow – I would like to explain in a general example how to follow the flow (phase) in product development etc. The development act requires a lot of resources. For details, please see before developing design. The content to be described is a development process that can […]

Control design

Control design 2 Sequence control and foundation and idea of ladder program

表紙

Sequence control of factory automation (FA) and foundation and ingenuity of ladder circuit Many factory automation (FA: production factory) facilities use sequence control. The control device that controls that is called PLC (Programmable Logic Controller: commonly known as sequencer) is used, and many of them are described by ladder circuits (some language description is also […]

Electrical design 1 Electrical and electrical design corresponding to heat

熱設計

Font size = “6”> Electrical and electrical design corresponding to heat I will think about the influence of control board and temperature of electrical equipment / electric equipment as electric / electric design corresponding to heat. I think that the safety factor etc. at the time of design will differ depending on the company, so […]

Control design

Control design1 Image control camera selection ~ control

画像制御 カメラ選定〜制御

画像制御 カメラ選定〜制御 From now on, products and facilities by image recognition and image control will increase more and more. Accuracy and design method will also change accordingly. Here I would like to explain how to use in an easy-to-understand manner. Inspection by imaging equipment, measurement example: ©Keyence/CV-Xseries I was thinking of writing in the order of […]

Flow of development

Avoid the danger! Risk assessment

リスクアセスメント

Avoid danger! Risk assessment Risk assessment is a way to grasp whether the dangers of products and equipment made are not hidden as logical thinking. Therefore, the risk here is not a risk of product strategy or product quality, simply speaking as a risk as “safety”. 1. Why is there a need to think about […]

Flow of development

Think about what you need before developing!

準備

Before developing, think about necessary things! Development is an act of creating new things to the world . (The design here refers to the design in terms of development activities.) Therefore, resources (human resources, funds, tools, materials) are required to be very large. We must judge what is really necessary taking into consideration the situation […]
