The invention relates to a multifunctional automatic substation detection device based on timing control. The device comprises a computer host, and various environment parameter measuring units are connected with the computer host and are used for detecting various environment parameters of a current position respectively. The computer host is further provided with a timing control module, a data processing and control module and a database module, wherein the timing control module is used for storing information of detection items needing to be developed at different time points and sending a trigger command to the data processing and control module when the time points are reached; the data processing and control module is used for receiving detection data sent by the environment parameter measuring units, storing the detection data in the database module, receiving the trigger command, determining the detection item needing to be developed at the current time point according to the trigger command and controlling the corresponding environment parameter measuring unit to work to obtain the corresponding detection data; the database module is used for storing the detection data of the various environment parameter measuring units. The device is high in automation degree, easy to operate, high in detection efficiency, compact in structure and convenient to carry.
