signal node

The electrical signal is generated through an influx of calcium into the cells in the SA node, causing a change in voltage which creates the current.

这个电信号是通过窦房结细胞的钙离子的内流产生的，它导致了膜电位的变化而由此产生了电流。

Using those components designs the system hardware resources. The central node module, the child nodes connected modules, The seismic signal detection module, the magnetic signal detection module and the node power supply module are designed.

主要进行了中心节点模块、子节点连接模块、地震动信号探测模块、磁信号探测模块和节点供电模块的设计，完成了相应电路模块实物的制作，并应用它们完成了系统硬件设计。

The consumers can use 400 V circuitry voltage as signal node power supply.

用户可以直接采用400V线路电压为信号节点电源.

The other hand, the central node receives the synchronized system clock and trigger signal from the timing signal fiber optic network, which provided by the core module.
