12F509 单片机程序编写
¥ 1000
一、上机通电软起动
开关插上电源,1-2秒后开关进入稳定状态后上电启动。
二、工作状态
1.正常运行,水龙头打开后,水流量≥60L/H流量干簧管断开,水泵一直运行,(绿、黄灯长亮)
2.缺水状态:水源在无水的时候,开关控制水泵运行12秒后停机,随后进入缺水定时循环启动状态。(绿、红长亮)
3.保压状态:水龙头关闭后,管道无泄漏,管道系统压力达到1.8Bar以上后开关控制水泵运行6秒后停机,进入水泵防抱死功能。(绿灯长亮)
4.压力自动启动:保压状态下,打开水龙头,管道压力下降达到1.5Bar左右,开关控制水泵启动运行。
5.按键强制启动:在缺水和保压状态下,按一下按键,开关控制水泵运行12秒。
三、缺水定时循环启动:
1.开关在缺水状态下,在无人为的动作后,水泵会在1小时启动,水泵运行12秒后,检查到水源还是没有水,水泵会在缺水状态下,自动定时第小时启动一次。
四、水泵防抱死功能
1.水龙头关闭,开关保压状态下,当水泵在24小时内无工作时,开关强制控制水泵启动,运转12秒钟。(保证水泵泵头的正常运行,防止电机抱死)

Sidekick — Inline help tips for your users
“ Hey everyone, I'm back with a brand new product launch. I've been working on Sidekick for the past couple of years since my first major product, blitapp.com was acquired back in 2019. I discovered the need for Sidekick when I was working on blitapp. I realized there were parts of the product that could use some extra explanation for the users. Similar to adding comments to code, the idea is that it's better to add documentation inline where users might encounter it, rather than in an external system such as a knowledge base. Sidekick solves this problem because it allows you to add inline help tips to educate your users in your product directly where they need the help. You can add a side pane, dialog or tooltips. To use Sidekick, simply sign up on sidekickup.com, download Sidekick Studio and you can start creating help tips on your site right away. To publish those tips, install Sidekick on your site by adding a script tag to the html. After that, you can add help tips on your site without modifying the code. Thanks for checking out the Sidekick beta launch! Right now, it's free to sign up and use Sidekick, but later this year beta users will be asked to start using one of our subscriptions. The transparent pricing can be found on the sidekickup.com homepage. Please give it a try and reach out if you have any feedback! ” – Justin Discussion | Link
