In the invention, the provincial subsystem represents a provincial unit, and the provincial scheduling instruction is the scheduling of the provincial unit in the whole provincial range made by the provincial angle; the ground subsystem represents a ground unit at the lower level of the provincial unit, and the ground unit scheduling instruction is self-scheduling in a local range; it will be appreciated, therefore, that province and land have a clear upper and lower relationship, and that the province subsystem, which is the province unit, has the authority to overall save all access resources, while the land subsystem, which is the land unit, can only schedule local access resources and receive jurisdictions of the province subsystem.
It is also worth noting that the provincial access resource and the local access resource in the present invention are two independent and non-coincident concepts, wherein the local access resource is a local access resource managed by the home-level subsystem, and the provincial access resource is an access resource not managed by the local subsystem, and whether the access resource is locally managed and classified as the local access resource depends on factors including the scale of the access resource, the area where the access resource is located and the controllable degree of the access resource (such as a nuclear power plant, etc. has high technical difficulty and has great harm after being out of control, and is supposed to be managed by the provincial level instead of being locally.
In the invention, the dispatching instructions are divided into two types, namely a grade dispatching instruction made by a grade unit, and one type is a grade dispatching instruction made by a grade unit, and in order to ensure independent autonomy of a grade subsystem, the grade subsystem does not directly carry out grade crossing operation on grade access resources under normal conditions, but divides the grade dispatching instruction into a grade dispatching instruction and a grade dispatching instruction, wherein the dispatching of the grade access resources in the grade subsystem is sent to the grade subsystem through the grade dispatching instruction and is dispatched through the grade subsystem, so that the autonomy of the operation of the grade subsystem is ensured; meanwhile, the execution result scoring system is established to supervise the ground level subsystem, and the execution result of each time of the ground level subsystem is quantitatively scored, so that the rationality of the ground level subsystem for scheduling the access resources of each ground level is judged, and the scheduling authority of the ground level subsystem is adjusted through the scheduling adjustment subsystem; in the subsequent resource scheduling process, reporting the provincial subsystem for the non-authority part in the provincial scheduling instruction and suspending the execution, and performing cross-level scheduling for the non-authority part of the provincial subsystem in the provincial scheduling instruction through the provincial subsystem; therefore, the independence and autonomy of the ground level subsystem are ensured, and under the action of the scheduling and adjusting subsystem, the provincial subsystem monitors and restricts the scheduling power of the provincial subsystem, and the three are mutually matched, so that the efficiency of resource scheduling can be effectively improved.
In another preferred embodiment of the present invention, the database subsystem records an execution score, the execution score being: after receiving the grade dispatching instruction or the secondary dispatching instruction, the grade client dispatches the related grade access resource through the grade server, sends the dispatching result to the provincial subsystem through the provincial communication end, and carries out quantitative grading according to the dispatching condition of each grade access resource in the dispatching instruction, wherein the quantitative grading is the execution grading.
In another preferred embodiment of the present invention, after receiving the provincial scheduling instruction, the provincial client divides the provincial client into a first-level scheduling instruction and a second-level scheduling instruction according to the types of scheduling resources included in the provincial scheduling instruction, wherein the scheduling resources included in the first-level scheduling instruction are provincial access resources, the scheduling resources included in the second-level scheduling instruction are local scheduling resources, and the local client sends the second-level scheduling instruction to the local client through the provincial local communication terminal, and the local client schedules the local access resources after receiving the second-level scheduling instruction.
In another preferred embodiment of the present invention, in the scheduling adjustment subsystem, the execution score of the censored resource unit in the destination scheduling instruction is retrieved from the background database, the average execution score of the censored resource unit is calculated according to the execution score in the history data, and when the average execution score is smaller than the set score threshold, the scheduling information of the censored resource unit is deleted from the land scheduling instruction, and the scheduling information of the censored resource unit is sent to the provincial subsystem through the provincial and local communication terminal; and when the average execution score is greater than or equal to the set score threshold, not processing.
In another preferred embodiment of the present invention, in the scheduling adjustment subsystem, before the provincial and local communication end sends the secondary scheduling instruction to the local client, the secondary scheduling instruction is acquired, names of different local access resources in the local scheduling instruction are sequentially acquired and defined as a checking resource unit, an execution score of the checking resource unit in the periodic scheduling instruction is called from the background database, an average execution score of the checking resource unit is calculated according to the execution score in the historical data, when the average execution score is smaller than a set score threshold, scheduling information of the checking resource unit is deleted from the secondary scheduling instruction, a tertiary scheduling instruction is generated according to the scheduling information of the checking resource unit, the tertiary scheduling instruction is sent to the provincial server, and the local access resources are scheduled through the provincial server; and when the average execution score is greater than or equal to the set score threshold, not processing.
It is noted here that, for the schedule adjustment subsystem, the execution time is that the schedule instruction has been issued but not executed, specifically: 1. the ground scheduling instruction reaches the ground client before being sent to the ground server; 2. the secondary scheduling instruction arrives at the ground client before it is sent to the ground server.
In another preferred embodiment of the present invention, the local subsystem sends a threshold-clearing request to the local subsystem through the local communication terminal, the threshold-clearing request includes at least information of a checking resource unit that needs to be relieved of the threshold, the threshold-clearing request is checked, and if the checking is passed, the average execution score of the checking resource unit is increased; if the audit is not passed, no change is made.
In this embodiment, in the process of passing the examination and improving the average execution score of the examination resource unit, the average execution score is improved to be equal to the set score threshold.
It can be understood that, for the level access resource with the revoked authority, the level subsystem cannot be scheduled, but can perform the deblocking by sending a deblocking request, after the deblocking, the average execution score of the level access resource can only be increased to be equal to the set score threshold, and the level access resource is in an assessment stage in a future period, and if a certain scheduling score is lower, the level access resource can be revoked again.
