| 电源 Power Supply 保证功率足够，尽量使用线性电源，门锁和控制器应分开供电。电源的安装尽可能靠近用电设备，以避免受到干扰和传输损耗。 Ensure sufficient power, use linear power supply as far as possible, door lock and controller should be powered separately. The power supply is installed as close as possible to the electrical equipment to avoid interference and transmission loss. 布线 wiring 分为电源线、通讯线、信号线，布线时注意强、弱电分开走线，两管相隔要求大于20cm左右。 It is divided into power line, communication line and signal line. When wiring, attention should be paid to the separation of strong and weak current. The distance between the two tubes should be more than 20 cm. 电源线：线径足够粗，采用多股导线。 Power Wire: Wire diameter is thick enough to use multiple wires. 信号线和通讯线：采用屏蔽五类双绞线。其中485总线必须使用双绞的一对线连接。在选购线材的时候建议采用4*0.5的四芯屏蔽线。 Signal and communication lines: shielded twisted pair of five types. The 485 bus must be connected by twisted pair of wires. Four-core shielding wire of 4*0.5 is recommended when choosing and purchasing wires. |
