Preferably, the present invention is applied to the real time embedded system of multi-screen processor, as vxWroks etc.
Beneficial effect of the present invention:
1, execute-in-place of the present invention is simple and easy to use: owing to be a kind of inline diagnosis invention based on embedded software, the characteristics of embedded software are real-time; Simultaneously, when the system task initialization, class object is registered in the chained list, and the relevant information of diagnostic task directly can propose, and not needing has wasted the time of data forwarding, provides the time to ensure for acquisition system faster needs diagnostic message like this.
2, need not increase special hardware device: because the present invention is based on the invention of embedded-type software architecture, so do not relate to special hardware device.
3, committed memory resource not: since each module class to as if exist with the form of registration chained list, do not relate to the committed memory space, can save internal memory like this.
4, do not influence other task executions of system, owing to just carry out this task when having only the user to diagnose, so do not influence the working time of other tasks.
5, can obtain the state of monitored object in real time: because the inline diagnosis task module is made up of a plurality of tasks, online expression can inquire the operation information of relevant processor in processor work; Be the information that the user can arbitrarily transfer to be needed, make things convenient for the user in time to inquire about, also avoid the waste of irrelevant information query time simultaneously, so can obtain information in real time.
Description of drawings
Fig. 1 is an embodiment of the invention inline diagnosis process flow diagram;
Fig. 2 is an embodiment of the invention inline diagnosis subprocess signal flow graph;
Fig. 3 is an embodiment of the invention embedded system initialization flowchart.
Embodiment
The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
Be illustrated in figure 1 as the inline diagnosis process flow diagram of the embodiment of the invention, concrete steps are as follows:
(1) inline diagnosis interface layer (being above-mentioned diagnose interface module) receives user's diagnosis request;
(2) the inline diagnosis interface layer transmits diagnosis request to inline diagnosis task management layer (being above-mentioned diagnostic task administration module), requires to transfer the diagnostic message of internal module;
(3) inline diagnosis task management layer is invoked at radiodiagnosis x task module (being above-mentioned diagnostic task processing module) and transfers the diagnostic message of internal module and return to the inline diagnosis interface layer from the object storage module;
The above-mentioned diagnosis management of the common composition of inline diagnosis task management layer and inline diagnosis task module processing module.
(4) the inline diagnosis interface layer returns the diagnostic message of internal module.
As Fig. 2 is embodiment of the invention inline diagnosis subprocess signal flow graph.Parent process is the task class of inline diagnosis task management, is used to realize above-mentioned diagnosis management processing module, and subprocess is the task class that internal module need be diagnosed, and subprocess is the derived class of parent process.Each subprocess promptly is the object module of a needs diagnosis, only each subprocess class object need be registered to the class object chained list, when the inline diagnosis task module calls chained list, can find this class object, and then the content that finds the user that realizes at subprocess to diagnose.
Because the diagnosis to each internal module all is to realize in subprocess, the communication between subprocess and the parent process belongs to the process level communication, and speed is very fast, and can not cause interference to system.
Be illustrated in figure 3 as embodiment of the invention embedded system initialization flowchart.
Step S1: be chained list of inline diagnosis generic task module creation, this chained list is used to store the class object that is about to registration;
Step S2: the internal module that needs is carried out the inline diagnosis task is created class object, class object is registered in the chained list of inline diagnosis task, needing to realize the particular content of diagnosis in the object of module;
Step S3: when inline diagnosis generic task interface layer is received order, analyze the internal module that needs diagnosis, the inline diagnosis generic task takes out the object of this module from chained list, and obtains the diagnostic information of needs and return.
