TABLE 1 field table for 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 referred to as an instruction code. The control command comprises two parts of a command code number and an instruction content of the SCPI instruction, wherein the command code number comprises an instruction type identifier, a test instrument type identifier, a node device identifier, a test instrument identifier and an SCPI instruction identifier.

Illustratively, the identification of the instruction type is represented by a 1-bit 10-ary number, for example, "1", "2", "3", "4" respectively represent different instruction types; the identifier of the test instrument type is represented by 2-bit 10-system number, for example, "01", "11", "15" respectively represent different test instrument types; the node device identification is represented by 2-bit 10-ary number, for example, "02", "20", "80" respectively represent different node devices; the identification of the test instrument is represented by 2-bit 10-ary number, for example, "01", "20", "51" respectively represent different test instruments; the identification of the SCPI instruction is represented by a 4-bit 10-ary number, for example, "0001" and "0100" represent different SCPI instructions.

Illustratively, the above identifiers are combined together in a predetermined order to form an instruction code, for example, the instruction code may be expressed as follows according to the order of the identifier of the instruction type, the identifier of the test equipment type, the identifier of the node equipment, the identifier of the test equipment, and the identifier of the SCPI instruction: abbcc deeee. Wherein, "a" represents an identifier of an instruction type, "BB" represents an identifier of a test instrument type, "CC" represents an identifier of a node device, "DD" represents an identifier of a test instrument, and "EEEE" represents an identifier of an SCPI instruction. For example, "30101020111" indicates an instruction with an instruction type of "3", a test equipment type of "01", a node device of "01", a test equipment of "02", and a SCIP instruction of "0111".

It should be understood that the above-mentioned identification of the control command and its data structure are only exemplary, and the embodiment of the present disclosure is not limited thereto, and for example, data forms such as json are also feasible.

Illustratively, the instruction content of the SCPI instruction includes a key and a parameter (optionally, a parameter for a set instruction and not a parameter for a query instruction). For example, the instruction of the SCPI instruction is "SOURce 1: VOLTage: protetection 110 (set PROTection VOLTage, target value is 110)", where "SOURce 1: VOLTage: protetection" is a portion (key) corresponding to the identifier of the SCPI instruction, and "110" is a parameter of the SCPI instruction. The instruction of the SCPI instruction is "SOURCE 1: VOLTage: PROTECTURE? (query PROTection VOLTage) ", wherein" SOURce1: VOLTage: PROTection? "is the portion (key) corresponding to the identification of the SCPI instruction whose instruction does not contain a parameter.

For example, but not limited to, the "instruction code" portion of the control command is separated from the "instruction" portion of the SCPI instruction by "|". For example, a control command may be represented as "30101020111 | SOURCE1: VOLTage: PROTECTURE? ".

In some embodiments, to control the timing of the SCPI instruction, the method further comprises: and determining the time sequence control information of the SCPI instruction, wherein the information carried by the control command also comprises the time sequence control information. The control commands containing the timing control information are shown in table 2.

Part 1	Section 2	Section 3
			Instruction code	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 delayed to be executed according to the delay information; or the timing control information may be set as time information indicating that the SCPI instruction is executed at that time.

In the above control command expression, the control command including the timing control information may be expressed as "instruction code | timing control information | SCPI instruction", in which the respective sections are separated by "|", and an exemplary control command is expressed as "30101020111 |50| SOURce1: volume: PROTection? ", which represents a time delay 50 (units may be milliseconds, etc. depending on the protocol) is performed.

In some embodiments, it may be the case that the parameter values returned for the query instruction are "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 can be represented by 2-bit 10-ary data, and is referred to as "FF", for example, for "0.05,0.14,0.45,1.23", when FF is 04, it represents that the 4 th value, i.e. 1.23, is extracted, and the other parameter values are ignored.

In some embodiments, generating a plurality of control commands forms a sequence of control commands. An exemplary control command sequence is as follows:

# - -select channel 2

32048010576|0|SELect:ch2 1

# - - - -setting horizontal scale

32048010282|0|HORizontal:SCAle 10.0

# - - - -setting the trigger mode

32048010634|0|TRIGger:A:MODe AUTO

Node apparatus 20 receives the control command or the control command sequence and executes its own control command.

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

In the embodiment of the present disclosure, the stored data packet includes the various identifiers (i.e., the instruction codes), so that the source of the data, the instruction used for collecting the data, and the like 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, and the node equipment is associated with one or more test instruments. And the node equipment acquires the control command of the node equipment 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 the embodiment of the present disclosure, the control command or the control command sequence is broadcasted, the node device may obtain the control commands sent to all the node devices, and the node device screens the control commands sent to the node device from the broadcasted control commands by using the identifier of the node device in the control commands.

In the embodiment of the present disclosure, the node device reads the identifier of the node device in the control command, compares the read identifier with the identifier of itself, and if the read identifier and the identifier of itself are consistent, the control command is sent to itself. Illustratively, as shown in the foregoing of the present disclosure, the identifier of the node device is set at a preset location ("CC" in abbcc data ee "), and the node device reads the value of the" CC "location to obtain the identifier of the node device indicated by the control command.

And step S306, under the condition that the control command corresponds to the node equipment, the node equipment determines the test instrument corresponding to the control command according to the identifier of the test instrument in the control command.

In the embodiment of the present disclosure, as in the foregoing example of the present disclosure, the identifier of the test instrument is set at the preset position ("DD" in abbcc data ee "), and the node device reads the value of the" DD "position to obtain the identifier of the test instrument indicated by the control command.

The instruction of the SCPI instruction is "SOURCE 1: VOLTage: PROTECTURE? (query PROTection VOLTage) ", wherein" SOURce1: VOLTage: PROTection? "is the portion (key) corresponding to the identification of the SCPI instruction whose instruction does not contain a parameter.

In some embodiments, in order to control the execution timing of the control name command, the information carried by the control command further includes: timing control information of the SCPI instruction. For example, the timing control information may be set as delay information indicating that the SCPI instruction is delayed to be executed according to the delay information; or the timing control information may be set as 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 above control command expression, the control command including the timing control information may be expressed as "instruction code | timing control information | SCPI instruction", in which each portion is divided by "|", and an exemplary control command is expressed as "30101020111 |50| SOURce1: VOLTage: PROTection? ", which represents a time delay 50 (units may be milliseconds, etc. depending on the protocol) is performed. After acquiring the instruction content of the SCPI instruction, the node equipment sets a timer of 50 units according to a rule, and sends the instruction content of the SCPI instruction to a corresponding test instrument when the timer is overtime.

In some embodiments, further comprising: the node equipment receives data sent by the determined 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: an identification of the type of instruction, an identification of the type of test instrument, an identification of the node device, an identification of the test instrument, an identification of the SCPI instruction, and the data.

In some examples, the node device sends the data packet, which includes various types of identifiers (i.e., command codes) and data in the corresponding control commands, as previously described. In some embodiments, the data packet further includes start and end timestamps of the control command, and the like, which are not limited and described in this disclosure.

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

In some embodiments, it may be the case that the parameter values returned for the query instruction are "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 can be represented by 2-bit 10-ary data, and is referred to as "FF", for example, for "0.05,0.14,0.45,1.23", when FF is 04, it represents that the 4 th value, i.e. 1.23, is extracted, and the other parameter values are ignored. Therefore, after receiving the data, the node device reads the identification of the value in the control command, and determines the data value to be acquired, for example, in the foregoing example, when FF is 04, the node device extracts the 4 th value of "0.05,0.14,0.45,1.23", that is, 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 acquires corresponding data in real time according to subscription configuration in the real-time database. In some embodiments, the node device may store the data packet directly in the real-time database, which is not limited by the embodiments of the present disclosure.

In the embodiment of the present disclosure, after the control command or the control command sequence is stored in the real-time database, the control command or the control command sequence may be read by a plurality of node devices, and the node devices may access the real-time database in real time to obtain the control command or the control command sequence 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.

Step S406, in a 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.

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

In step S409, the node device generates a packet.

The information carried by the data packet includes: the identification of the instruction type, the identification of the test instrument type, the identification of the node device, the identification of the test instrument, the identification of the 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.

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