Illustratively, the above-mentioned identifications are combined together in a predetermined order to form an instruction code, e.g., in the order of identification of the instruction type, identification of the test instrument type, identification of the node device, identification of the test instrument, and identification of the SCPI instruction, the instruction code may be expressed as: ABBCCDDEEEE. Wherein, "a" represents an identification of an instruction type, "BB" represents an identification of a test instrument type, "CC" represents an identification of a node device, "DD" represents an identification of a test instrument, and "EEEE" represents an identification of an SCPI instruction. For example, "30101020111" indicates an instruction of the instruction type "3", the test instrument type "01", the node device "01", the test instrument "02", and the SCIP instruction "0111".

Part 1	Part 2	Part 3
			Code of instruction	Timing control information	Instruction content of SCPI instruction

For example, the timing control information may be set as delay information indicating that the SCPI instruction is to be executed with delay according to the delay information; or the timing control information may be set to time information indicating that the SCPI instruction is executed at that time.

In the control command representation described above, a control command containing timing control information may be represented as an "instruction code |timing control information|instruction of SCPI instruction", in which the respective parts are separated by "|", and an exemplary control command is represented as "30101020111|50|source 1:volume: process? ", which means that the delay 50 (in units of milliseconds, etc., depending on the protocol) is performed.

In some embodiments, this may be the case for the parameter value returned by the query instruction, "0.05,0.14,0.45,1.23". Thus, the control command may also include an identification of the value. The identification of the value may be represented by 2-bit 10-ary data, referred to as "FF", for example, for "0.05,0.14,0.45,1.23", when ff=04, it represents that the 4 th value, i.e. 1.23, is extracted, and other parameter values are negligible.

In some embodiments, after the control command is generated, the control command or sequence of control commands is sent. For example, a control command or sequence of control commands is broadcast to node device 20. The node device 20 receives the control command or the control command sequence, and executes its own control command.

In some embodiments, the control commands or sequences of control commands are processed using a real-time database. After generating the control commands or control command sequences, the control commands or control command sequences are sent to the real database, from which node device 20 may be configured to read the control commands or control command sequences in real time. In some embodiments, a real-time database is provided at server 30, and node device 20 communicates with server 30 to read control commands or control command sequences in real-time from the real-time database provided thereon.

In some embodiments, the query command enables data collection, and node device 20 may be configured to periodically send instructions of the SCPI instruction to its associated test instrument 10, periodically collecting data from the test instrument 10.

In the disclosed embodiment, the stored data packet includes the various identifiers (i.e., instruction codes) described above, so that the source of the data, the instructions used to collect the data, etc. are determined according to the identifiers.

The embodiment of the disclosure also provides an SCPI instruction management method for spacecraft power system evaluation, which is applied to node equipment, wherein the node equipment is associated with one or more test instruments. The node equipment acquires own control command according to the control command or the identification information in the control command.

As shown in fig. 3, the method includes steps S302 to S308.

In step S302, the node device acquires a control command.

The information carried by the control command comprises: identification of instruction type, identification of test instrument type, identification of node device, identification of test instrument, identification of SCPI instruction, and instruction content of SCPI instruction.

In embodiments of the present disclosure, as described in the foregoing portions of the present disclosure, various types of identifiers in control commands are collectively referred to as instruction codes, and in some embodiments, the identifiers are organized together in a predetermined order, each of the identifiers is set as desired to a corresponding number of bits, and the instruction codes are partitioned from the instruction content of the SCPI instruction using a separator "|".

In embodiments of the present disclosure, the node device may listen for a control command or sequence of control commands, which in some embodiments are sent into a real-time database, where the node device may be configured to read the control command or sequence of control commands in real-time.

In step S304, the node device determines whether the control command corresponds to the node device according to the identifier of the node device in the control command.

In the embodiment of the disclosure, the control command or the control command sequence is broadcast, the node device can acquire the control commands sent to all the node devices, and the node device uses the identification of the node device in the control commands to screen the control commands sent to the node device from the broadcast control commands.

In the embodiment of the disclosure, the node device reads the identifier of the node device in the control command, compares the read identifier with the identifier of the node device, and if the read identifier is consistent with the identifier of the node device, the control command is sent to the node device. Illustratively, as previously described in this disclosure, the identity of the node device is set at a preset location ("CC" in ABBCCDDEEEEE "), and the node device reads the value of the" CC "location to obtain the identity of the node device indicated by the control command.

In step S306, in the case that the control command corresponds to the node device, the node device determines the test instrument corresponding to the control command according to the identifier of the test instrument in the control command.

In an embodiment of the present disclosure, as in the foregoing examples of the present disclosure, the identification of the test instrument is set at a preset location ("DD" in ABBCCDDEEEEE "), and the node device reads the value of the" DD "location to obtain the identification of the test instrument indicated by the control command.

In step S308, the node device sends the instruction content of the SCPI instruction in the control command to the determined test instrument.

In an embodiment of the present disclosure, as in the foregoing examples of the present disclosure, the instruction content of the SCPI instruction is set at a preset location, and the node device reads the value of the location, to obtain the instruction content of the SCPI instruction.

In the present embodiment, the instruction content of the SCPI instruction includes a key and parameters (the parameters are optional, have parameters for the set instruction, and do not include parameters for the query instruction). For example, the instruction of the SCPI instruction is "SOURce 1:VOLTage:PROTection 110 (set protection voltage, target value is 110)", where "SOURce 1:volume:process" is a part (key) corresponding to the identification of the SCPI instruction, and "110" is a parameter of the SCPI instruction. The SCPI instruction has an instruction of "SOURce 1:VOLTage:PROTection? (inquiry protection voltage) ", wherein" SOURce 1:volume:procedure? "is the part (key) of the SCPI instruction corresponding to the identification, and the instruction of the SCPI instruction does not contain parameters.

In some embodiments, to control the execution timing of the control name command, the information carried by the control command further includes: timing control information for SCPI instructions. For example, the timing control information may be set as delay information indicating that the SCPI instruction is to be executed with delay according to the delay information; or the timing control information may be set to time information indicating that the SCPI instruction is executed at that time.

In the method, the node equipment sends the instruction content of the SCPI instruction in the control command to the determined test instrument according to the time sequence control information. In the control command representation described above, a control command containing timing control information may be represented as "instruction code |timing control information|instruction of SCPI instruction", in which the respective parts are separated by "|", and an exemplary control command is represented as "30101020111|50|SOURce 1:VOLTage:PROTection? ", which means that the delay 50 (in units of milliseconds, etc., depending on the protocol) is performed. After obtaining the instruction content of the SCPI instruction, the node equipment sets a 50-unit timer according to the rule, and sends the instruction content of the SCPI instruction to the corresponding test instrument when the timer times out.

In some embodiments, further comprising: the node equipment receives the determined data sent by the test instrument in response to the instruction content of the SCPI instruction; the node equipment generates a data packet, wherein the information carried by the data packet comprises: identification of instruction type, identification of test instrument type, identification of node device, identification of test instrument, identification of SCPI instruction, and the data.

In some examples, the node device transmits the data packet, which, as previously described, includes various types of identification (i.e., instruction code) and data in the corresponding control instruction. In some embodiments, the data packet further includes start and end time stamps of the control command, etc., which are not limited and described in detail in the embodiments of the disclosure.

In some embodiments, for each control command, the node device may send data packets generated in response to the control command separately. In other embodiments, the node device packages and transmits a data packet corresponding to a plurality of control commands (for example, but not limited to, a certain period of time), where the packaged data includes a plurality of the foregoing data packets, and each data packet includes an instruction guiding portion and a data portion.

In some embodiments, this may be the case for the parameter value returned by the query instruction, "0.05,0.14,0.45,1.23". Thus, the control command may also include an identification of the value. The identification of the value may be represented by 2-bit 10-ary data, referred to as "FF", for example, for "0.05,0.14,0.45,1.23", when ff=04, it represents that the 4 th value, i.e. 1.23, is extracted, and other parameter values are negligible. Thus, the node device, upon receiving the data, reads the identification of the value in the control command, determines the data value to be acquired, for example, in the foregoing example, when ff=04, represents extracting the 4 th value, i.e. 1.23, in "0.05,0.14,0.45,1.23".

In some embodiments, the node device sends the data packet to the server, the server stores the data packet in the real-time database, and the client obtains corresponding data in real time according to the subscription configuration in the real-time database. In some embodiments, the node device may store the data packets directly into a real-time database, which is not limited by embodiments of the present disclosure.

The embodiment of the disclosure also provides a method for testing a spacecraft power system, as shown in fig. 4, which comprises steps S401 to S413.

In some examples, the test task includes a configuration file that generates a control command or sequence of control commands from which the server generates the control command or sequence of control commands.

In some examples, the test tasks of the client include control commands or sequences of control commands.

In step S403, the server stores the generated control command or control command sequence in the real-time database for the node device to read.

In step S404, the node device reads the control command in the real-time database.

In the embodiment of the disclosure, after the control commands or the control command sequences are stored in the real-time database, the control commands or the control command sequences can be read by a plurality of node devices, and the node devices can access the real-time database in real time to acquire the control commands or the control command sequences in real time.

Step S405, for the control command read by the node device, the node device determines whether the control command corresponds to the node device according to the identifier of the node device in the control command.

In step S406, in the case that the control command corresponds to the node device, the node device determines the test instrument corresponding to the control command according to the identifier of the test instrument in the control command.

In step S407, the node device sends the instruction content of the SCPI instruction in the control command to the determined test instrument.

In step S408, in the case that the test instrument has feedback data, the node device receives the determined data sent by the test instrument in response to the instruction content of the SCPI instruction.

In step S409, the node apparatus generates a data packet.

The information carried by the data packet comprises: identification of instruction type, identification of test instrument type, identification of node device, identification of test instrument, identification of SCPI instruction in the corresponding control command, and the data.

In step S410, the node device transmits the data packet to be received by the server.

In step S411, the server receives the data packet sent by the node device.

In step S412, the server stores the data packet in the real-time database.

In the embodiment of the disclosure, the stored information is information carried by the data packet, including various identifiers in the control command corresponding to the data packet, and data acquired in response to the control command.

In step S413, the client obtains data from the real-time database according to the subscription configuration and displays the data.

In the embodiment of the present disclosure, the client may display data through the image user interface, and the display of the data may refer to known techniques, which are not described in detail in the embodiment of the present disclosure.
