And the following steps: the operation control device of the portable terminal can display a prohibition instruction on a user interface of the portable terminal to remind a user of the portable terminal to adjust the moving process in time so as to change the operation process of the portable terminal, thereby realizing the limitation operation control of the portable terminal.

The identity and registration request of the controller is verified by each node device in the blockchain system, verification passing (if more than 50% or 2/3 of the node devices represent approval, verification passing) indicates successful registration, and the controller has both the public key and the private key. In this embodiment, the running data of the target object 301 may also be issued to the blockchain, specifically, the running data may be encrypted by using a private key of a controller and then issued to the blockchain, the node device in the blockchain system verifies the encrypted data by using a public key of the controller, and after the verification is passed, the running data is stored in a block and the block is added to the blockchain. Since the operation data and the limitation data of the target object 301 are stored in the blockchain and cannot be tampered, the operation process of the target object 301 can be effectively traced, that is, whether the actual operation process of the target object 301 meets the requirement of limitation operation can be supervised and controlled by the operation data and the limitation flight data in the blockchain, so that whether the operation rule of the national government, an air navigation control mechanism, a traffic control mechanism or other target object management mechanisms is violated by the target object 301 can be supervised and controlled, and effective management of the movement process of the target object 301 is realized.

The operating parameters herein may include, but are not limited to, operating altitude, operating speed, etc., and accordingly, the parameter limit ranges may include an operating altitude limit range, an operating speed limit range, etc. The parameter limit range may be set according to actual situations, for example, the operation height limit range may be [90 meters, 102 meters ], [0, 120 meters), etc., and the operation speed limit range may be [60 km/hr ], 81 km/hr ], [0 km/hr, 120 km/hr), etc. Taking the target object as an aircraft as an example, setting the flying height of the aircraft as 150 meters and the limit range of the flying height as [0, 120 meters ], when the operating parameter exceeds the limit range of the parameter, generating a third prohibiting instruction, wherein the third prohibiting instruction is used for indicating that the flying height of the aircraft needs to be reduced to be within the limit range of the flying height to continue to operate, otherwise, the limit flying rule is violated. In addition, taking the target object as the portable terminal as an example, the set operation speed limit range may be [60 km/h, 81 km/h ], and the operation speed of the portable terminal is set to be 50 km/h, the operation parameter exceeds the parameter limit range, and a third prohibition instruction is generated, wherein the third prohibition instruction is used for indicating that the portable terminal needs to increase the operation speed to be within the parameter limit range, otherwise, the limit regulation is violated.

Here, the associated position of the target object may refer to a running start position of the target object, for example: the associated position carried by the fourth prohibition instruction is the flight starting point position of the aircraft, and the fourth prohibition instruction indicates that the aircraft returns to the flight starting point position. The associated position of the target object may refer to any position away from the exclusion zone region, where a distance between the any position and the exclusion zone region is greater than a second distance threshold, for example: the associated position carried by the fourth prohibition instruction is a position far away from the forbidden area, and the fourth prohibition instruction indicates that the portable terminal needs to operate to the corresponding position far away from the forbidden area. By the fourth forbidden instruction, the target object can be prevented from intruding into the forbidden area to violate the corresponding forbidden instruction.
S504, outputting a prohibition instruction to control the operation of the target object.
The manner of outputting the prohibition instruction may include sending, displaying, etc., which is not limited by the embodiment of the present application; for example: the operation control device of the aircraft can send a prohibition instruction to the hardware device of the aircraft, wherein the prohibition instruction is used for instructing the hardware device of the aircraft to respond to the prohibition instruction and control the flight process of the aircraft so as to realize the restricted flight of the aircraft; and the following steps: the operation control device of the portable terminal may display a prohibition instruction on a user interface of the portable terminal, and at this time, the prohibition instruction may be "the front is a restricted area, please turn to operate", "the front is a restricted area, please operate to an associated location", etc., to remind a user of the portable terminal to adjust the moving process in time to change the operation process of the portable terminal, so as to implement the restricted operation control of the portable terminal.
