The invention discloses a device for remotely monitoring the running state of a cooling tower in real time, and belongs to the technical field of cooling tower working state monitoring. The device comprises a microprocessor, and a motor current detection module, a fan rotating speed detection module, a current and rotating speed detection channel switching module, a water inlet and outlet temperature detection module, a parameter configuration module and a data remote transmission module are connected with the microprocessor. The device also comprises a power supply module which is simultaneously connected with the microprocessor, the motor current detection module, the fan rotating speed detection module, the water inlet and outlet temperature detection module, the parameter configurationmodule and the data remote transmission module. The working states of all parts of the cooling tower can be accurately judged and known in time, maintenance or replacement measures are convenient totake, and stable and efficient operation of the cooling tower is guaranteed.
