标 题: 电工 | 用breaker interlock简易接入发电机
发信站: BBS 未名空间站 (Thu Aug 15 22:13:59 2013, 美东)
嗯,去年sandy的时候很惨,停了两周电,到第三天的时候弄到了一个发电机,因为要
开暖气,但是暖气的两路电,一路在家里的总panel,另一路的车库的100A subpanel,
所以当时是索性冒险直接将发电机接入家里的整个电网,唯一的保护措施是把家里的总
开关关死,然后沾上层层胶带。。。电来了以后马上把所有临时的线路拆掉,怕被人查
到。。。
现在大半年过去了,怕又停电,LD提了好几次,终于在上周末按规范把发电机电路完成
,不怕简陋,摆上这个版来聊以充数,贻笑大方。
code的要求是你需要有一个装置,确保让utility company和你的发电机不能给家里的
任何一路线路同时供电。绝大多数人用的是transfer switch,这个电路接起来比较麻
烦,而且不太能解决我们家的问题。

http://www.mitbbs.com/article_t0/Programming/31312727.html
我做了如下测试:
- 纯计算.
- 12 core xeon
- 200 concurrent threads(大家都说200个太浪费,我当然没坐过此类应用, 不过我
测了12,24,50,100,结果都差不多,没提高多少)
- one big array: long[20000]
- every thread handles 50,000 interlocked.increment (get random item from
the array and do increment)
- total number of interlocked.increment = 1千万 (10M)
average time spent: 0.2 second.
也就是每秒50M. |

简单地 Interlocked.Decrement( T[X234,S2] ) 怕是不行吧?

系统主要特点:
- 多线程。(老魏没有给出具体多少个线程,假定100个吧。我的12 core intel xeon轻
轻松松100 thread)
- 无锁。
- 单机。
数据结构:
1. 全国1000条线 (X1, X2, X... , X1000), 每条20个区段 (S1, S2, S3... S20)。
2. 每条线的每个区段的票的总数计为:T[X1,S1], T[X1, S2]....... T[X1000, S20]
抢票程序(注意举得例子是联票)
1. 100个thread处理收到的请求
2. 每个请求包括三个参数(线路, 起始站,结束战). 比如(234次列车, 济南, 上
海)。 (注意, 234次列车是从沈阳出发,到上海的, 济南是第5个区的开始,上海最
后一个区段的结束)
3. 计算过程就是把234次列车从济南到上海的每个区段的票数做interlocked.

- Interlocked.Decrement( T[X234,S5] )

Interlock, as the time told, locked the two hands too tight.
interlock, bascially, is good for the smaller palm/hand. it means if you
think you can't grab the club naturally, you can use interlock grip (or
change ur grib to smaller size.)

I believe the shift interlock only prevents the shift from being moved OUT
of Park without the brake being applied, (they were an outgrowth of the of
the supposed Audi 5000 unintended acceleration issue from the 80's). Your
transmission may balk at shifting from drive to reverse, but that is not a
shift interlock issue. I confirmed that this morning in my 2007 car going

interlock的优点是直接装在主盒子上,相对便宜,可以给整个房子供电(不是同时)

5/6000w),只要你把其他的都关了。缺点一个是每次使用,心里得有数哪些可以同时开
