The control module is a logical function module in the power system that implements operational control for devices within the home local area network. This definition originates from the power industry standard DL/T 1398.1—2014 “Smart Home System – Part 1: General Principles” [1]. Its core functions include signal conversion and delay control, which can be decomposed into the first control unit (responsible for signal conversion and amplification) and the second control unit (executing delay operations) [3]. This module achieves communication between the central controller and terminal devices through wireless networking technologies such as ZigBee and LoRa, and supports command transmission and status feedback in low-power network environments [4] [6].
In terms of application fields, the control module has expanded to multiple scenarios such as energy storage thermal management systems (controlling cell temperatures through liquid cooling technology) [2], industrial automation (realizing safety interlocks based on Boolean logic and PLC) [5], and automotive electronics (implementing reverse polarity protection and overvoltage protection) [4]. Typical hardware implementations include the CC2530 chip networking architecture, MCU main control devices, and ARM processor platforms [6-7]. Current technological development focuses on processor performance upgrades, packaging process optimization (CoC/SiP integration technology), and environmental stability testing (including latch test and low-voltage surge test)
