Data acquisition and control system of pulsed power supply for multi-load

A data acquisition and control system of pulsed power supply for multi-load, wherein the data acquisition and control system of pulsed power supply for multi-load is a pulsed power supply data acquisition and control system configured to connect to a near-earth space plasma environment ground-based simulation device, and wherein a pulsed power supply of the near-earth space plasma environment ground-based simulation device comprises a power distribution system (7) and 18 sets of power supplies, the power distribution system (7) being configured to supply power to the 18 sets of power supplies at the same time;

• the data acquisition and control system of pulsed power supply for multi-load comprises a remote control system (1), two optical fiber switches (2), synchronous trigger equipment (3), an emergency stop button/access control switch (5), and safety interlocking equipment (6);
• the remote control system (1) comprises an engineer station (11) and an operator station (12);
• the engineer station (11) is configured to:
• set the pulsed power supply for use,
• set the quantity of modules of the pulsed power supply,
• set a time sequence of current output for each power module, and
• set upper temperature limits of dump resistors and crowbar resistors inside discharge modules of each set of power supply, and a data acquisition sampling interval of data acquisition, wherein proceeding to next discharging operation of the power supply is not allowed only after temperatures of the dump resistors and the crowbar resistors after each power discharge are within the set upper limits;
• the operator station (12) is configured to:
• select the pulsed power supply for use,
• further control the charge, discharge and dump of the power supply,
• set charging voltage and trigger time sequence of the power supply put in operation, and
• display real-time voltage of the power supply, real-time temperature of the crowbar resistors, real-time temperature of the dump resistors, the status of a local control unit, the status of the synchronous trigger equipment, the status of the safety interlocking equipment, operation status of the power supply, and status parameters,
• wherein in case of failure:
• the remote control system:
• receives a protection signal sent by the safety interlocking equipment, and
• sends an instruction of stopping charging and bleeding to the local control unit, and
• each module turns off a charging switch and turns on a dump switch, such that the energy of the power supply can be safely and quickly released,
• the two optical fiber switches are connected by optical fiber to prevent electromagnetic interference, and the two optical fiber switches are connected and are data exchange equipment for the remote control system (1), a data storage system (4), the synchronous trigger equipment (3) and the safety interlocking equipment (6);
• the synchronous trigger equipment (3) is configured to;
• receive various time sequence parameters and instructions sent by the remote control system (1), and
• send a trigger signal to the local control unit of the pulsed power supply according to a specific time sequence;
• and
• receive a protection signal sent by the safety interlocking equipment (6) in case of failure, so as to lock the synchronous trigger equipment (3), and prohibit the synchronous trigger equipment from transmitting the trigger signal;
• an emergency stop button in the emergency stop button/access control switch (5) is pressed in case of a failure or other emergency in a charging process of the pulsed power supply system, so as to:
• send an emergency stop signal to the remote control system (1), the power distribution system (7) and the safety interlocking equipment (6);
• wherein responsive to the emergency stop signal:
• the remote control system (1) shows an abnormal status,
• the power distribution system (7) automatically disconnects from each set of power supply,
• the safety interlocking equipment (6) locks trigger action of the synchronous trigger equipment (3), and
• at this time, discharge operation of the power supply is disabled;
• wherein, concurrently with the remote control system showing abnormal status, the remote control system (1) sends action instructions to a local control unit of each power supply, and the module of each set of power supply automatically turns off the charging switch to stop a charger from charging the discharge module, and automatically turns on the dump switch to release the energy of each module;
• an access control switch in the emergency stop button/access control switch (5) is configured to close a door of a power supply room no person to enter the power supply room during normal operation of the pulsed power supply system, and send an “access control breaking” signal to the remote control system (1), the power distribution system (7) and the safety interlocking equipment (6) when the door of the power supply room is opened accidentally;
• then:
• the remote control system (1) shows an abnormal status,
• the power distribution system (7) automatically disconnects from each set of power supply,
• the safety interlocking equipment (6) locks the triggering action of the synchronous trigger equipment, and
• concurrently with the locking, discharge operation of the power supply is disabled;
• the remote control system (1) sends action instructions to a local control unit of each power supply, and
• the module of each set of power supply automatically turns off the charging switch to stop the charger from charging the discharge module, and automatically turns on the dump switch to release the energy of each module;
• and
• the safety interlocking equipment (6) is configured to receive:
• a failure signal reported by the local control unit of each set of pulsed power supply in case of power failure during the operation of the pulsed power supply system,
• a press signal of the emergency stop button in a control room, and
• an opening signal of the access control switch of the power supply room,
• wherein, when receiving any of the failure signal, press signal, and opening signal, the safety interlocking equipment outputs a protection signal to the synchronous trigger equipment and the remote control system, such that the function of discharge triggering of the synchronous trigger equipment is locked, wherein the remote control system (1) sends an instruction of stopping charging and performing dump to each local control unit, and wherein each module turns off the charging switch and turns on the dump switch to safely and rapidly release energy of each power supply.
