To enhance the reliability of a communication system using a superimposition signal.SOLUTION: A signal processing device for mediating communication between electrical equipment (6) operating downstream of a communication system (1) and an equipment control device (52, 52A, 3) for controlling one or more electrical equipment upstream includes a first computing unit (105) for generating a superposition target signal indicating at least first information, and a superimposition circuit (18) for generating a superimposition signal in which a superimposition target signal is superimposed on an operation signal corresponding to the state of an operation element (13) of the electric equipment or an operation signal for controlling the operation element. The first computing unit controls to generate no superimposition target signal while a second computing unit (605) for generating a superimposition target signal indicating at least second information is in an active state, and generate the superimposition target signal when the second computing unit is in a standby state. The first computing unit and the second computing unit are operated with electric power for generating an operation signal.SELECTED DRAWING: Figure 7 【課題】重畳信号を用いた通信システムの信頼性を高める。【解決手段】通信システム（１）の下流で動作する電気機器（６）と、上流で１以上の電気機器を制御する機器制御装置（５２、５２Ａ、３）との間の通信を仲介する信号処理装置であって、少なくとも第１の情報を示す重畳対象信号を生成する第１演算部（１０５）と、電気機器の動作素子（１３）の状態に応じた動作信号、または、動作素子を制御する動作信号に、重畳対象信号を重畳させた重畳信号を生成する重畳回路（１８）とを備え、第１演算部は、少なくとも第２の情報を示す重畳対象信号を生成する第２演算部（６０５）がアクティブ状態となっている期間に、重畳対象信号の生成を行わず、第２演算部がスタンバイ状態となっている期間に、重畳対象信号の生成を行うように制御し、第１演算部および第２演算部は、動作信号を生成するための電力によって動作するものである。【選択図】図７
