Acquisition terminal, load management center and quantum safety load management system

The invention discloses an acquisition terminal, a load management center and a quantum security load management system, the quantum security load management system comprises the acquisition terminal and the load management center, and a communication module of the acquisition terminal and a global quantum security network in the load management center are in communication connection through a 4G/5G virtual private network; the quantum security encryption module obtains power data to be transmitted, selects a key, carries out key expansion by using an expansion algorithm, carries out quantum encryption on the power data and the key with the same length to form a quantum security transmission frame, and transmits the quantum security transmission frame to the global quantum security network through the communication module. The global quantum security network carries out key expansion and carries out quantum decryption on the quantum security transmission frame through the expanded key to obtain power data of
