Of the present utility model have a following beneficial effect:
The micro-kernel device (hereinafter to be referred as the micro-kernel device) that is applied to automobile air conditioner control panel series products control software of the present utility model switches by the multitask of software, guaranteed each task the device hardware clock guarantee in a big way in each task executions all be consistent, can not cause the variation significantly of device overall performance owing to the change of a task/module.
The variation of this apparatus structure logic causes the micro-kernel device all to have superior performance, uniformity and robustness in many-sides such as concurrent development, test, performances.Because each function that the micro-kernel device will install is divided in the corresponding software task, so, after determining, the task division framework of device can carry out the concurrent development of team to each task, and linear systemic circulation and based on the AM/BAM device that interrupts because the close-coupled between each functional module, the breadth and depth of concurrent development all is limited.To software test, each task of micro-kernel device can be carried out unit testing separately, (the task of Ti Jiaoing can not adopt the mock mode can to carry out the integration testing of each task after the task framework is finished, the mock mode is the emulation component mode), perhaps because intercoupling of each task is very little, in the task of having neither part nor lot in test can be limited in very among a small circle to the influence of the test result of the task of participating in test).And linear systemic circulation and based on the same because close-coupled of each task module of the AM/BAM device that interrupts, causing independently unit testing and early stage integration testing all is suitable difficulty.At the final aspect of performance of software, as previously mentioned, the control software of micro-kernel framework can improve the consistency of performance that is better than traditional structure software.
Crucial, because limited soft, the hardware resource limitations of car air-conditioner control panel series products, make the embedded OS of existing commercialization (OS operating system) almost not have applicable space, and the utility model has been realized real-time, uniformity, the robustness of the air-conditioning panel control of product function under the limited software and hardware resources condition.Because the micro-kernel device does not use special soft, hardware resource, so the transplanting between different hardware platforms is also fairly simple, convenience.
By the consistency of performance of device, concurrent development, the performance of superperformances such as unit and integration testing is the construction cycle of lifting device quality, control device obviously.

Can increase and decrease corresponding module according to application need exactly with one of having a few of micro-kernel mode.The CAN/LIN module all needs with regard to not every device, and the ADC that device provides also has different configurations with the timer service in different application.
The micro-kernel device that is applied to automobile air conditioner control panel series products control software can comprise 2 above timers, pulse width modulation (being called for short PWM) waveform generator and and the concrete analog-and digital-port resource of application adaptation on 8 or 16 single-chip microcomputer platforms.Can select for use is PIC16F877A (possessing 33 input/output ports and 8 10 analog digital conversion ports), as Fig. 4.
Reference examples, Fig. 1 and Fig. 2, if adopt simple linear systemic circulation or based on the AM/BAM device that interrupts, factors such as the change of control device functional requirement or control logic change can cause some functional modules of a. to revise or the adding of the new functional module of b. or the merging of c. existing capability module are deleted and waited software to change.Contrast top linear systemic circulation software configuration, can find based on the AM/BAM device software structure of interrupting and the structured flowchart of micro-kernel device software structure, any change of above-mentioned a.b.c. all will cause linear systemic circulation software configuration and change based on the control performance of the software of the AM/BAM device that interrupts, thereby influence the control characteristic of resulting device.For example, the control logic computing module is because the change of algorithm, cause become 10ms running time by original 1ms, then Zhuan Zhi overall control also will increase 4ms running time, if Zhuan Zhi total cycle of operation is 20ms before changing, satisfy the requirement that the user operates collection, and just will become after changing, will cause the realizable operating delay of user near 30ms.
And the multitask of micro-kernel device by software switched, guaranteed each task the device hardware clock guarantee in a big way in each task executions all be consistent, can not cause the variation significantly of device overall performance owing to the change of a task/module.
The variation of this apparatus structure logic, cause the micro-kernel device at concurrent development, test, many-sides such as performance all have superior performance, uniformity and robustness. because each function that the micro-kernel device will install is divided in the corresponding software task, so, after determining, the task division framework of device can carry out the concurrent development of team to each task, and linear systemic circulation and based on the AM/BAM device that interrupts because the close-coupled between each functional module, the breadth and depth of concurrent development all is limited. to software test, each task of micro-kernel device can be carried out unit testing separately, (the task of Ti Jiaoing can not adopt the mock mode can to carry out the integration testing of each task after the task framework is finished, perhaps because intercoupling of each task is very little, in the task of having neither part nor lot in test can be limited in very among a small circle to the influence of the test result of the task of participating in test). and linear systemic circulation and same because the close-coupled of each task module based on the AM/BAM device that interrupts, it all is quite difficult causing independently unit testing and early stage integration testing. at the final aspect of performance of software, as previously mentioned, the control software of micro-kernel framework can improve the consistency of performance that is better than traditional structure software.
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
