安全回路-這個(gè)電路上有校驗(yàn)各個(gè)安全部件是否動(dòng)作的安全感應(yīng)開關(guān)，主機(jī)的過熱保護(hù)開關(guān)，端站的上下極限開關(guān)，底坑轎頂機(jī)房的急停開關(guān)。

Safety circuit - there are safety induction switches on this circuit to check whether each safety component acts, overheat protection switch of main engine, upper and lower limit switch of terminal station, emergency stop switch of pit car roof machine room.

門鎖回路-每個(gè)廳門的門鎖觸點(diǎn)開關(guān)。用于檢測每個(gè)廳門是否都是關(guān)閉狀態(tài)

Door lock return - door lock contact switch for each hall door. It is used to detect whether each hall door is closed

平層感應(yīng)器（選層器）-一般是光電開關(guān)或者電磁感應(yīng)開關(guān)加隔磁板，現(xiàn)在也有讀磁條的APD，用于判斷樓層的平層位置

Leveling inductor (layer selector) - generally photoelectric switch or electromagnetic induction switch plus magnetic separator. Now there is APD for reading magnetic stripe, which is used to judge the leveling position of the floor

主機(jī)上的旋轉(zhuǎn)編碼器-目前大部分都整合在主機(jī)上，一般是增量型的旋轉(zhuǎn)編碼器，用于計(jì)算電機(jī)速度，配合PID算法計(jì)算變頻器輸出。

Rotary encoder on the host - at present, most of them are integrated on the host, generally incremental rotary encoder, which is used to calculate the motor speed and calculate the inverter output with PID algorithm.

----以上僅提到一些普通用戶不太容易知道的，

----The above only mentioned some common users are not easy to know,

結(jié)合評(píng)論中的提醒還有安裝在轎門上的光幕或者安全觸板，以及一般安裝在轎底的稱重傳感器。

Combined with the reminders in the comments, there are light screens or safety touch panels installed on the car door, and load cells generally installed on the car bottom.
