Detailed Description
Example 1
(1) Two global dynamic tables
Two global dynamic tables are maintained in the terminal:
module information table: and after the storage module is inserted into the terminal, the module information acquired by the terminal.
The specific content comprises the following steps: module ID information, module type, module channel type, module private information, slot number of the accessed terminal, equipment file information of the module and other module information.
Module rule table: all rules according to which the terminal operation module is based are stored.
The specific content comprises the following steps:
1) storing module type information (a module white list and a module black list) supported or not supported by the terminal; 2) Storing the priorities of different types of modules supported by the terminal; 3) storing the allowed data interaction time period of the module supported by the terminal; 4) storing all module information synchronized from the module information table; 5) storing the corresponding state (normal, abnormal and frozen) information of the module; 6) and storing system resource information (such as an allocated task number, the size of a cache space, a device descriptor and the like) corresponding to the module.
(2) Module registration and logout flow
Module registration process:
when the module is inserted into the slot of the terminal or the slot of the terminal in which the module is inserted is electrified, the terminal can acquire module information, then inquire a module rule table, filter the modules which do not accord with the rule, add the module information into the module information table for the modules which accord with the rule, then distribute system resources (opening up data transceiving cache space, adding tasks, adding equipment descriptors and the like) for transceiving module data, finally update the module rule table, update the module state to be normal, and add the system resource information corresponding to the module.
And (3) module logout flow:
when the module is unplugged from the terminal slot position or the terminal slot position inserted with the module is powered off, the terminal can acquire the information of the changed module, determine whether the module occupies the system resources or not by inquiring the module rule table, if so, release the corresponding system resources, and then update the module information table and the module rule table.
(3) Module fault recovery and isolation process
The module does not carry out data interaction with the terminal according to the protocol for a plurality of times continuously, and the module is considered to be in fault.
The recovery of the abnormal module is attempted by restarting the terminal.
The specific steps are that when the module is considered to be in fault, the slot position corresponding to the module is powered off, the module is triggered to log off the process, and then the module is powered on, and the module is triggered to register; then judging whether the restarted module is recovered to be normal or not; if the module is abnormal, releasing the system resources applied by the module, and then updating the corresponding state of the module in the module rule table to be abnormal.
Finally, the module with abnormal function only occupies the table entries in the module information table and the module rule table, does not occupy system resources, and does not perform data interaction with the system, thereby achieving the purpose of isolation.
(4) Scheduling of module resources
When system resources are insufficient or there is a requirement for power consumption of the whole system, scheduling of resources for the module is required.
The resource scheduling is mainly carried out by using module priority and module interaction time period in a module rule table. The module priority refers to allocating different levels to various modules according to the importance degree of the service requirement; the module interaction time period means that a certain type of module does not need to perform data interaction with the terminal every moment, but limits a certain time period to perform data interaction.
For the module which is just accessed, if the data interaction time period in the module rule table has a requirement and the current system time is not in the required time period, adding the module into the module information table, but not distributing the system resources, and finally setting the module state to be the frozen state in the module rule table.
The system has tasks to continuously check and update the module rule table, when the frozen module is detected to meet the requirement of the interaction time period, the system resources are distributed, the state in the module rule table is updated to be a normal state, and then the subsequent data interaction processing is carried out.
When the priorities of the modules are the same, the modules inserted preferentially allocate system resources preferentially.
When the priorities of the modules are different, after a module with high priority is inserted, the resource occupied by the module with the lowest priority in the system needs to be released, the module state is set to be frozen, and then the system resource is allocated to the newly added module. If the resources are not enough, the module with the lower priority level needs to release the resources occupied by the module. When the priority of the inserted module is lower than the module already existing in the current system, the module is not processed.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
