Referring to fig. 3, the data processing method provided in the embodiment of the present invention implements load balancing processing and abnormal satellite task scheduling processing by using the multi-satellite measurement and control data processing system, and specifically includes the following operation steps:
step S100: the management equipment sequences the plurality of satellite measurement and control processing equipment, and numbers each satellite measurement and control processing equipment one by one to obtain a monitoring list of the satellite measurement and control processing equipment;
step S200: each satellite measurement and control device reports an online running satellite task and task flow corresponding to the satellite task to a management device in real time, and meanwhile, the management device calculates and forms a task load monitoring list for each satellite measurement and control processing device; the task load monitoring list is used for sequencing all on-line running satellite tasks of the current satellite measurement and control processing equipment according to the sequence of task flow from high to low;

For example, in a specific application scenario (see fig. 4 for details), the monitoring list of the satellite measurement and control processing device totally stores 100 satellite measurement and control processing devices, and the satellite measurement and control processing devices report their own processing loads to the management device in real time. When the management device finds that the current work load of the satellite measurement and control processing device No. 1 exceeds 85% (that is, the data flow of the current satellite task is too large, and the total task flow of the satellite measurement and control processing device No. 1 exceeds 85% of the standard early warning value of the current satellite measurement and control processing device), the satellite processing task with larger current flow in the satellite measurement and control processing device No. 1 is unloaded (multiple satellite processing tasks of the current satellite measurement and control processing device are monitored), another idle satellite measurement and control processing device No. 2 is dynamically selected, the unloaded satellite processing task file is transmitted to the idle satellite measurement and control processing device No. 2, the satellite processing task is dynamically loaded on the satellite measurement and control processing device No. 2, the loads of the satellite measurement and control processing device No. 1 and the satellite measurement and control processing device No. 2 are balanced and controlled, and based on the result, the task processing load balance of the system cluster device is realized.

In the step S210, the algorithm for calculating the standard early warning value of the management device according to the current measurement and control processing device is as follows:
C＝f*(a1*act1+a2*act2+...+am*actm)/m；
the method comprises the following steps that C represents a standard early warning value, m is the number of types of preset attribute information, a1 and a2 \8230amrepresent the weight of each preset attribute information, act1 and act2 \8230amrepresent the value of the attribute information of the current measurement and control processing equipment when the attribute information is executed according to the highest standard load; f represents the average task flow value obtained by a large number of experiments when the alarm abnormality of the measurement and control processing equipment with the same model occurs.
For example: the set attribute information includes the CPU calculation capacity, the cache space and the maximum thread number, and then m takes the value of 3. The management device sets a score for each attribute information, the score being a number between 0 and 1. The score of the CPU computing capacity is reported to be 0.8, the score of the cache space is reported to be 0.5, the score of the maximum number of threads is reported to be 0.5 and the like (namely act1, act2 823030act 3).
