The execution judgment of the satellite load instruction is automatically carried out through software.
In the using process of the method, three aspects of support need to be provided:
1. an acquisition interface for providing a load execution plan;
2. an analysis result query interface of the remote measurement parameters;
3. the user is required to describe in advance in the rule configuration file each parameter and the associated manner of influence that is affected during the execution of the respective load action.
Referring to fig. 3, the satellite load instruction execution judgment system of the invention comprises a human-computer interaction unit, a load rule configuration unit and a load plan monitoring unit.

The load rule configuration unit comprises a rule adding module, a rule configuration template downloading module, a rule configuration file importing module, a rule opening and closing module and a single rule changing module which can be carried out on an interface one by one.
The load rule configuration step is divided into two parts for configuration, wherein the first part of configuration information is rule object basic configuration and fault information configuration, and the second part of configuration information is rule judgment parameter configuration.
The rule object basic configuration includes a judged satellite, a rule name, and a judgment object (load execution action).
The fault information configuration is corresponding error description information when the execution is unsuccessful according to the judgment result, and comprises a fault name, alarm content, a fault level, whether a task is influenced or not and the like.
The rule judging parameter configuration is a telemetering parameter which needs to be checked in the judging process, and can be configured with a plurality of pieces of information, wherein each piece of information needs to be configured with a judging frame number and a corresponding judging method besides a parameter name.
The judgment method comprises four types: threshold method, state-keeping method, time-varying method, and arrival method.
The interpretation frame number means a fault-tolerant frame number which represents the number of times of occurrence of the telemetry parameters which do not meet the rules, within the range of the number of times, the execution of the action is considered to be successful, and when the interpretation frame number is exceeded, the execution of the action is considered to be failed.
For the threshold method, threshold information needs to be configured, which indicates an interval in which the parameter value should be normally located, and is defined by the minimum value and the maximum value of the threshold.
For the state-keeping method, it is necessary to configure a constant value that the parameter should be kept.
For the time-varying method, it is necessary to arrange the time-varying interval, the offset amount per variation, and the error.
For the reach method, it is necessary to specify the value to which the parameter value should reach and the number of occurrences.
The load plan monitoring unit comprises all load execution plans (executed and unexecuted) of the current satellite, plan execution time and judged plan execution result viewing, load instruction execution judgment and load execution result and detail storage.
Referring to fig. 2 and 4, after the support of the three aspects is completed, the method of the present invention obtains several items of latest plan information from the interface of the load execution plan, then adds a timing task for each plan, after the time of the load execution plan is reached, associates with the load action execution judgment logic configured by the user, determines the telemetry parameters to be judged, and finally obtains the telemetry parameter values according to the query interface of the telemetry parameters, and executes the judgment.

2) adding the plan of the 'sequential playback to ground' action to a timing queue, and starting countdown;
3) executing a judgment mechanism when the end time of executing the action plan is reached;
4) inquiring a judgment rule of the action of 'playback in sequence to ground';
5) inquiring all values of 'digital demodulator A plus power off' in the execution period of the load action, judging the values by using a state holding method, judging whether the values are kept to be 1 or not, and if the values are consistent, indicating that the parameters are normal;
6) inquiring all values of the level of the data transmission channel control unit 1 and the level of the data transmission channel control unit 2 during the execution period of the load action, judging whether the parameter values are between 2 and 5 all the time by using a threshold value method, and if the parameter values are consistent, indicating that the parameter is normal;
7) inquiring all values of 'power supply voltage of satellite-borne equipment 2' in the load action execution period, judging whether the parameter value is between 35 and 46.2 by using a threshold value method, and if so, indicating that the parameter is normal;
8) inquiring all values of the parameter of the data transmission execution state during the execution period of the load action, judging whether the value reaches 5.5, and if so, representing that the parameter accords with the expectation;
