The invention provides a patrol task issuing device and belongs to the field of a power system. The device comprises an environment monitoring sensor, a circuit load sensor, an environment judgment server, a load judgment server, a master control computer, a patrol task issuing server and a communication base station. The environment monitoring sensor is connected with the patrol task issuing server through the environment judgment server, the circuit load sensor is connected with the patrol task issuing server sequentially through the load judgment server and the master control computer, and the patrol task issuing server is connected with the communication base station. By means of the patrol task issuing device provided with the patrol task issuing server, numbers and related parameters of power supply circuits needing to be patrolled are issued in a unified mode so that nearby patrol personnel can selectively receive patrol tasks according to self task schedule. Environment conditions and load conditions of the power supply circuit are taken into consideration in the issued patrol tasks. Thus, missing detection is avoided, and patrol timeliness is further improved.
