A remote control system for a freezer and a cooling tower apparatus is provided to expand a control unit of an added attaching apparatus easily and to increase stability and efficiency. A remote control system for a freezer and a cooling tower apparatus includes a control/monitor unit. The control/monitor unit includes a micro controller, an NVRAM(Non-Volatile Ram), a SRAM(Static Ram), a ROM(Read Only Memory), an OSC(Oscillator), an RTC(Real Time Clock), a display unit, a control value control unit, an alarm unit, an analog/digital I/O(input/output), a digital I/O, an analog input, an ADC(Analog-Digital Converter), a serial I/O, a LAN converter. The control/monitor unit controls the freezer and the cooling tower apparatus by outputting an applied control signal after comparing a preset control value with a detect and contact signal inputted from a power switch of a detector and a motor control unit(10), operates the remote control and monitor by comparing the preset control value with a remote control and monitor data request order signal inputted from one of a wireless communication terminal and a remote PC(90) and outputting the control signal to an applied apparatus control unit(100). |
