In the embodiment of the present disclosure, the node device 20 may be associated with one or more test instruments 10. The node device 20 is configured to communicate with the test instrument 10 associated with it to collect data from the test instrument 10 or perform setting operations on the test instrument 10.

In the disclosed embodiment, an identifier is assigned to each node device 20, an identifier of the test instrument type is assigned to each test instrument, and an identifier of the test instrument is classified for each test instrument 10. The identifier of the node device 20 can be associated with the attribute information of the node device 20, for example, the identifier of the node device 20 is associated with the IP address, MAC address, etc. of the node device 20. The identifier of the test instrument 10 can be associated with the attribute information of the test instrument 10, for example, the identifier of the test instrument 10 is associated with the IP address, etc. of the test instrument 10. The identifier of the test instrument type can be associated with the attribute information of the corresponding type of test instrument, for example, the identifier of the test instrument type is associated with information such as which communication interface the test instrument supports.

In the disclosed embodiment, the test instrument 10 and the node device 20 use the standard command set for programmable instruments (SCPI) to achieve remote control, but it is not limited to this. SCPI is a standardized instrument programming language based on the existing standards IEEE488.1 and IEEE488.2, and follows multiple standards such as floating-point arithmetic rules in the IEEE754 standard, ISO646 information exchange 7-bit coding symbols (equivalent to ASCII programming), etc. It uses a set of tree-like hierarchical structured command sets, is a universal general instrument model, and uses signal-oriented measurement.

The commands in the standard command set of programmable instruments correspond to a key press on the device panel. In remote operation mode, one or more SCPI commands can complete the same task. Multiple commands make up a command set.

In the implementation of the present disclosure, SCPI instructions include but are not limited to two functions (instruction types):

1) Setting instructions to change the operating status of the test instrument, that is, set operations, for example, turning on/off the power output, etc.;

2) Query instructions for querying the status of the test instrument, that is, query operations, for example, reading the output voltage value, etc.

Query commands usually end with a question mark "?". Some commands can be used to set or query the instrument.

Generally, each test instrument has its own developer manual, which describes in detail the SCPI commands it supports in the form of a syntax tree. The SCPI commands in the syntax tree form cannot be used directly, but can be used after being parsed into a single SCPI command.

A syntax tree for an example SCPI command is shown below:

[SOURce:]

PULSe

:TRANsition[:LEADing]<Time>[Unit] Set the rise/fall time

:TRANsition[:LEADing]? <Time>[Unit] Query the rise/fall time

:WIDTh

:HIGH <Time> [Unit] Set the LevelA (higher level) pulse width

:HIGH? <Time> [Unit] Query the pulse width of LevelA (higher level)

:WIDTh

:LOW <Time> [Unit] Set the Level B (lower level) pulse width

:LOW? <Time> [Unit] Query the pulse width of Level B (lower level)

After parsing the above syntax tree, we can get the following instructions:

PULSe:TRANsition Set the rise/fall time

PULSe:TRANsition? Query rise/fall time

PULSe:WIDTh:HIGH Set LevelA (higher level) pulse width

PULSe:WIDTh:HIGH? Query the pulse width of LevelA (higher level)

PULSe:WIDTh:LOW Set LevelB (lower level) pulse width

PULSe:WIDTh:LOW? Query the pulse width of Level B (lower level)

In the disclosed embodiment, identifiers are assigned to SCIP instructions, and the identifiers of SCPI instructions can distinguish different SCPI instructions. For example, the identifier of the SCIP instruction "PULSe:WIDTh:HIGH" is "0001", and the identifier of the SCIP instruction "PULSe:TRANsition" is "0002".

In the disclosed embodiments, local non-standard SCPI command expansion can be provided to facilitate more effective and complete use of the functions of the evaluation equipment, provide a more complete means for the evaluation process, and thus obtain more accurate evaluation results.

In the embodiments of the present disclosure, SCPI instructions of all types of test instruments involved in the test can be obtained to form a SCPI instruction set for each type of test instrument. Different SCPI instructions are distinguished by the identifier of the SCPI instruction. In some cases, the SCPI instructions of the same type of test instruments are the same, that is, each test instrument of the same type has the same SCPI instruction set. The instruction content of the SCPI instruction includes keywords and parameters (parameters are optional, and parameters are included for setting instructions, but not for query instructions). In the present disclosure, the identifier of the SCPI instruction refers to the identifier corresponding to the keyword.

It should be understood that the system for evaluating a spacecraft power system shown in FIG. 1 is merely an exemplary description of an embodiment of the present disclosure, and is not a limitation of the system for evaluating a spacecraft power system.

The following describes an embodiment of the present disclosure based on the system shown in FIG1 .

In some embodiments of the present disclosure, the information carried by the control command includes: an identifier of the instruction type, an identifier of the test instrument type, an identifier of the node device, an identifier of the test instrument, an identifier of the SCPI instruction, and the instruction content of the SCPI instruction. The information carried by the data packet in response to the control command includes: an identifier of the instruction type in the corresponding control command, an identifier of the test instrument type, an identifier of the node device, an identifier of the test instrument, an identifier of the SCPI instruction, and the acquired data. In the present disclosure, various types of identification information are collectively referred to as "instruction code".

In some embodiments of the present disclosure, the information carried by the control command also includes: timing control information, and the timing control information may include delay information or time information, which is not limited in the present disclosure.

In the present disclosure, according to various identifications in the control command, SCPI instructions can be sent to multiple types of multiple test instruments and distinguished; according to various identifications in the data packet, the instructions, test instruments, node devices and other information for obtaining the data can be determined without complex retrieval. Moreover, based on these identification information, it is convenient to write or automatically generate control commands and improve the readability of control commands.

The embodiment of the present disclosure provides a SCPI command management method for spacecraft power system evaluation, which can be applied to a client 50 or a server 30 to generate control commands for a test instrument 10. A plurality of control commands form a control command sequence, and executing the control commands in the control command sequence implements a series of operations, including collecting data from the test instrument 10 and setting the state of the test instrument 10.

As shown in FIG. 2 , the method includes steps S202 to S204 .

Step S202, determining the identifier of the instruction type, the identifier of the test instrument type, the identifier of the node device, the identifier of the test instrument, the identifier of the SCPI instruction, and the instruction content of the SCPI instruction.

Step S204, generating a control command, wherein the information carried by the control command includes: an identifier of the instruction type, an identifier of the test instrument type, an identifier of the node device, an identifier of the test instrument, an identifier of the SCPI instruction, and instruction content of the SCPI instruction.

In the embodiment of the present disclosure, the fields included in the generated control command are shown in Table 1.

Table 1 Field table of control commands

In the embodiment of the present disclosure, the identifier of the instruction type, the identifier of the test instrument type, the identifier of the node device, the identifier of the test instrument, and the identifier of the SCPI instruction in the control command are combined into an instruction code. The control command includes two parts: the instruction code and the instruction content of the SCPI instruction. The instruction code includes the identifier of the instruction type, the identifier of the test instrument type, the identifier of the node device, the identifier of the test instrument, and the identifier of the SCPI instruction.

Exemplarily, the identifier of the instruction type is represented by a 1-digit decimal number, for example, "1", "2", "3", and "4" represent different instruction types respectively; the identifier of the test instrument type is represented by a 2-digit decimal number, for example, "01", "11", and "15" represent different test instrument types respectively; the identifier of the node device is represented by a 2-digit decimal number, for example, "02", "20", and "80" represent different node devices respectively; the identifier of the test instrument is represented by a 2-digit decimal number, for example, "01", "20", and "51" represent different test instruments respectively; the identifier of the SCPI instruction is represented by a 4-digit decimal number, for example, "0001" and "0100" represent different SCPI instructions.

Exemplarily, the above-mentioned identifiers are combined together in a predetermined order to form an instruction code. For example, according to the order of the identifier of the instruction type, the identifier of the test instrument type, the identifier of the node device, the identifier of the test instrument, and the identifier of the SCPI instruction, the instruction code can be expressed as: ABBCCDDEEEE. Among them, "A" represents the identifier of the instruction type, "BB" represents the identifier of the test instrument type, "CC" represents the identifier of the node device, "DD" represents the identifier of the test instrument, and "EEEE" represents the identifier of the SCPI instruction. For example, "30101020111" represents an instruction with an instruction type of "3", a test instrument type of "01", a node device of "01", a test instrument of "02", and a SCIP instruction of "0111".

It should be understood that the above identification of the control command and its data structure are only for illustrative purposes, and the embodiments of the present disclosure do not limit this. For example, it is also feasible to use data formats such as JSON.

Exemplarily, the instruction content of the SCPI instruction includes keywords and parameters (parameters are optional, and parameters are included for setting instructions, but not for query instructions). For example, the instruction of the SCPI instruction is "SOURce 1:VOLTage:PROTection 110 (set protection voltage, target value is 110)", where "SOURce 1:VOLTage:PROTection" is the part (keyword) corresponding to the identifier of the SCPI instruction, and "110" is the parameter of the SCPI instruction. The instruction of the SCPI instruction is "SOURce 1:VOLTage:PROTection?" (query protection voltage)", where "SOURce 1:VOLTage:PROTection?" is the part (keyword) corresponding to the identifier of the SCPI instruction, and the instruction of the SCPI instruction does not contain parameters.

Exemplarily, the "command code" part and the "SCPI command" part in the control command are separated by "|", but not limited thereto. For example, the control command can be expressed as "30101020111|SOURce 1:VOLTage:PROTection?".

In some embodiments, in order to control the timing of the SCPI command, the method further includes: determining the timing control information of the SCPI command, wherein the information carried by the control command also includes the timing control information. The control command including the timing control information is shown in Table 2.

Table 2 Control commands containing timing control information

Part 1 Part 2 Part 3 Instruction code Timing control information SCPI command content

Exemplarily, the timing control information may be set as delay information, indicating that the execution of the SCPI instruction is delayed according to the delay information; or the timing control information may be set as time information, indicating that the SCPI instruction is executed at the time.

Using the above control command representation method, a control command containing timing control information can be expressed as "instruction code|timing control information|SCPI instruction", wherein each part is separated by "|". An exemplary control command is expressed as "30101020111|50|SOURce1:VOLTage:PROTection?", which indicates execution with a delay of 50 (the unit may be milliseconds, etc., depending on the protocol).

In some embodiments, the parameter value returned by the query command may be "0.05, 0.14, 0.45, 1.23". Therefore, the control command may also include a value identifier. The value identifier may be represented by a 2-digit decimal number, denoted by "FF". For example, for "0.05, 0.14, 0.45, 1.23", when FF = 04, it means that the fourth value, i.e., 1.23, is extracted, and other parameter values may be ignored.

In some embodiments, multiple control commands are generated to form a control command sequence. An exemplary control command sequence is as follows:

#----Select channel 2

32048010576|0|SELect:ch2 1

#----Set the horizontal scale

32048010282|0|HORizontal:SCAle 10.0

#----Set the trigger mode

32048010634|0|TRIGger:A:MODe AUTO

#----Zero point setting of channel 2 (V)

32048010057|0|CH2:POSition-3.0

#----Offset setting of channel 2 (V)

32048010055|0|CH2:OFFSet 0.00

#----Vertical scale setting of channel 2 (V)

32048010063|0|CH2:VOLts 1.0

In some embodiments, after the control command is generated, the control command or the control command sequence is sent, for example, the control command or the control command sequence is broadcast to the 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, a real-time database is used to process control commands or control command sequences. After generating a control command or a control command sequence, the control command or the control command sequence is sent to a real number database, and the node device 20 can be configured to read the control command or the control command sequence from the real-time database in real time. In some embodiments, the real-time database is set on the server 30, and the node device 20 communicates with the server 30 to read the control command or the control command sequence in real time from the real-time database set thereon.

In some embodiments, after sending the control command, the method further includes: receiving a data packet sent by the corresponding node device in response to the control command, wherein the information carried by the data packet includes: an identifier of the instruction type, an identifier of the test instrument type, an identifier of the node device, an identifier of the test instrument, an identifier of the SCPI instruction, and data obtained by the corresponding test instrument in response to the instruction content of the SCPI instruction; and storing the data packet. It should be understood that the data packet may also include other information, such as the start and end timestamps of the SCPI instruction, etc., which will not be elaborated in the embodiments of the present disclosure.

Exemplarily, the control command sent is "30101020111|50|SOURce1:VOLTage:PROTection?", and the received data packet carries "30101020111" (ie, the instruction code composed of the above multiple identifiers) and the queried data.

In some embodiments, the query command implements data collection, and the node device 20 can be configured to periodically send SCPI instructions to its associated test instrument 10 to periodically collect data from the test instrument 10.

In the disclosed embodiment, the stored data packets contain the above-mentioned various identifiers (ie, instruction codes), so that the source of the data, the instructions used to collect the data, etc. can be determined based on these identifiers.

The embodiment of the present disclosure also provides a SCPI command management method for spacecraft power system evaluation, which is applied to a node device, and the node device is associated with one or more test instruments. The node device obtains its own control command according to the control command or identification information in the control command.

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

Step S302: The node device obtains a control command.

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

In the embodiments of the present disclosure, as described in the preceding part of the present disclosure, various identifiers in the control command are collectively referred to as instruction codes. In some embodiments, these identifiers are organized together in a predetermined order, and each identifier is set with a corresponding number of bits as required. The instruction code and the instruction content of the SCPI instruction are separated by a separator “|”.

In an embodiment of the present disclosure, the node device may monitor a control command or a control command sequence. In some embodiments, the control command or the control command is sent to a real-time database, and the node device may be configured to read the control command or the control command sequence in the real-time database in real time.

Step S304: The node device determines whether the control command corresponds to the node device according to the node device identifier in the control command.

In the disclosed embodiment, a control command or a control command sequence is broadcast, and a node device can obtain control commands sent to all node devices. The node device uses the node device identifier in the control command to filter the control command sent to itself from the broadcasted control commands.

In the embodiment of the present disclosure, the node device reads the node device identification in the control command, compares the read identification with its own identification, and if the two are consistent, the control command is sent to itself. Exemplarily, as shown in the foregoing of the present disclosure, the node device identification is set at a preset position ("CC" in "ABBCCDDEEEEE"), and the node device reads the value of the "CC" position to obtain the identification of the node device indicated by the control command.

Step S306: When the control command corresponds to the node device, the node device determines the test device corresponding to the control command according to the identification of the test device in the control command.

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

Step S308: The node device sends the instruction content of the SCPI instruction in the control command to the determined test instrument.

In the embodiment of the present disclosure, as in the aforementioned example of the present disclosure, the instruction content of the SCPI instruction is set at a preset position, and the node device reads the value of the position to obtain the instruction content of the SCPI instruction.

In the present embodiment, the instruction content of the SCPI instruction includes keywords and parameters (parameters are optional, and parameters are included for setting instructions, but not for querying instructions). For example, the instruction of the SCPI instruction is "SOURce 1:VOLTage:PROTection 110 (set protection voltage, target value is 110)", where "SOURce 1:VOLTage:PROTection" is the part (keyword) corresponding to the identifier of the SCPI instruction, and "110" is the parameter of the SCPI instruction. The instruction of the SCPI instruction is "SOURce 1:VOLTage:PROTection?" (query protection voltage)", where "SOURce 1:VOLTage:PROTection?" is the part (keyword) corresponding to the identifier of the SCPI instruction, and the instruction of this SCPI instruction does not contain parameters.

In some embodiments, in order to control the execution timing of the control command, the information carried by the control command also includes: timing control information of the SCPI instruction. Exemplarily, the timing control information can be set as delay information, indicating that the execution of the SCPI instruction is delayed according to the delay information; or the timing control information can be set as time information, indicating that the SCPI instruction is executed at this time.

In the above method, the node device sends the instruction content of the SCPI instruction in the control command to the determined test instrument according to the timing control information. In the above control command representation method, the control command containing the timing control information can be expressed as "instruction code|timing control information|SCPI instruction", wherein each part is separated by "|", and an exemplary control command is expressed as "30101020111|50|SOURce 1:VOLTage:PROTection?", which indicates execution with a delay of 50 (the unit may be milliseconds, etc., according to the protocol). After obtaining the instruction content of the SCPI instruction, the node device 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, it also includes: the node device receives the data sent by the determined test instrument in response to the instruction content of the SCPI instruction; the node device generates a data packet, wherein the information carried by the data packet includes: an identifier of the instruction type, an identifier of the test instrument type, an identifier of the node device, an identifier of the test instrument, an identifier of the SCPI instruction, and the data.

In some examples, the node device sends the data packet, which, as described above, includes various identifiers (i.e., instruction codes) and data in the corresponding control instructions.
