Description
技术领域technical field
本发明涉及微波仪器领域，特别涉及一种提高微波仪器控制效率的方法。The invention relates to the field of microwave instruments, in particular to a method for improving the control efficiency of microwave instruments.
背景技术Background technique
现在微波测量仪器大都采用了智能控制技术，内嵌工控机或单片机等智能处理器，通过复杂的软件程序控制微波仪器内部的各个功能单元完成一系列的测试和测量功能。软件执行一系列的控制指令按顺序操作微波各功能单元和部件，并等待每个功能单元和部件完成动作并达到稳定状态，再返回仪器测量结果。由于现在的微波仪器内部电路和微波单元很多，软件程序通过总线操作仪器内部单元需要时间很短甚至可以忽略，但等待这些电路单元完成动作后达到稳定状态经常需要花费较长的时间，每次操作完一些功能部件后，经常需要加入等待指令，等待功能部件达到稳定状态，再进行下一步操作，这就导致微波仪器测量效率的低下。Nowadays, most microwave measuring instruments adopt intelligent control technology, embedded with intelligent processors such as industrial computer or single-chip microcomputer, and control each functional unit inside the microwave instrument through complex software programs to complete a series of test and measurement functions. The software executes a series of control instructions to operate the functional units and components of the microwave in sequence, and waits for each functional unit and component to complete the action and reach a stable state before returning the measurement results of the instrument. Since there are many internal circuits and microwave units in microwave instruments today, the time required for software programs to operate the internal units of the instrument through the bus is very short or even negligible, but it often takes a long time to wait for these circuit units to complete their actions and reach a stable state. After completing some functional components, it is often necessary to add a waiting command to wait for the functional components to reach a stable state before proceeding to the next step, which leads to low measurement efficiency of microwave instruments.
微波仪器中装备有很多的微波、电路单元部件，当仪器的控制软件设置仪器中电路单元的时间少于电路单元的稳定时间时，通常需要加入Sleep()或Delay()等延时等待指令，而每一个等待指令的执行都会延长仪器的测量时间，降低测量效率，对此目前还没有专门的解决方案。Microwave instruments are equipped with a lot of microwave and circuit unit components. When the control software of the instrument sets the time of the circuit unit in the instrument to be less than the stabilization time of the circuit unit, it is usually necessary to add Sleep() or Delay() and other delay waiting instructions. The execution of each waiting command will prolong the measurement time of the instrument and reduce the measurement efficiency, and there is no special solution for this at present.
随着微波电路部件的增加，测试软件设置中达到状态稳定需要的等待时间越来越多，因而大大降低了微波仪器的测试效率。微波电路单元越多，效率降低越明显。With the increase of microwave circuit components, more and more waiting time is required to achieve a stable state in the test software setting, thus greatly reducing the test efficiency of microwave instruments. The more microwave circuit units, the more obvious the reduction in efficiency.

When all the microwave circuit units are set or only the last microwave circuit unit is left, call the WaitOver function to insert the waiting time. And wait for all the waiting time of this control thread to be executed before returning and exiting.

当收到WaitOver函数传入的时刻参数，并完成时刻参数的比较后，该进程停止执行，等待时间一直达到线程句柄关联的时间队列中的最晚等待时刻值为止，再发送事件通知WaitOver函数返回退出。When the time parameter passed in by the WaitOver function is received and the comparison of the time parameter is completed, the process stops executing until the waiting time reaches the latest waiting time value in the time queue associated with the thread handle, and then an event is sent to notify the WaitOver function to return quit.

If the earliest completion waiting time is earlier than this time point, use this time point Instead of the earliest completion waiting time, store it in the queue identified by the thread handle, otherwise, replace the earliest completion waiting time identified by the thread handle with this time point passed in by the function;

具体实施方式Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
本发明把每个微波电路部件设置完后需要的稳定时间进行队列组合，把所有的等待时间进行复用，并进行排队优化，从而最终实现测量时间的减少和测量效率的提高。The invention combines the stabilization time required by each microwave circuit component into a queue, multiplexes all the waiting time, and optimizes the queue, so as to finally realize the reduction of measurement time and the improvement of measurement efficiency.
下面结合附图对本发明提高微波仪器控制效率的方法进行详细说明：The method for improving microwave instrument control efficiency of the present invention is described in detail below in conjunction with accompanying drawing:
本发明的方法通过等待时间管理线程对插入的等待时间进行管理和运算，并完成所有微波电路单元需要的等待时间的处理。仪器的每一个控制线程中，设置完仪器的微波电路单元，需要插入等待的地方调用Wait函数，当所有微波电路单元都设置完毕或只剩最后一个微波电路单元后，调用WaitOver函数插入等待时间，并等所有的本控制线程的等待时间执行完再返回退出。The method of the invention manages and calculates the inserted waiting time through the waiting time management thread, and completes the processing of the waiting time required by all microwave circuit units. In each control thread of the instrument, after setting the microwave circuit unit of the instrument, call the Wait function at the waiting place. When all the microwave circuit units are set or only the last microwave circuit unit is left, call the WaitOver function to insert the waiting time. And wait for all the waiting time of this control thread to be executed before returning and exiting.
如图1所示，等待时间管理线程实现原理包括以下步骤：As shown in Figure 1, the implementation principle of the waiting time management thread includes the following steps:
每当收到Wait传入的时刻参数和线程句柄后，根据线程句柄从该线程句柄关联的等待时间缓存中读取最早完成时刻，与自己保存的时刻参数进行比较，将更晚或更大的时刻参数保存；Whenever the time parameter and thread handle passed in by Wait are received, the earliest completion time is read from the waiting time buffer associated with the thread handle according to the thread handle, and compared with the time parameter saved by itself, the later or larger Save time parameters;
当收到WaitOver函数传入的时刻参数，并完成时刻参数的比较后，就需要该进程停止执行，等待时间一直达到线程句柄关联的时间队列中的最晚等待时刻值为止，再发送事件通知WaitOver函数返回退出。When the time parameter passed in by the WaitOver function is received and the time parameter comparison is completed, the process needs to stop executing until the waiting time reaches the latest waiting time value in the time queue associated with the thread handle, and then send an event notification to WaitOver Function returns to exit.
接收到Wait函数发送的等待时间长度不需要等待时间管理线程等待，只有当WaiOver发送过来的时间值才最终完成执行等待。The waiting time length sent by the Wait function does not need to wait for the waiting time management thread to wait, only when the time value sent by WaiOver is finally completed to execute the waiting.
本发明的方法包括两个设置等待函数，一个是插入等待时间Wait(doubleeDelayLength)函数，另一个是执行等待时间WaitOver(double eDelayLength)函数，其中Wait函数用于除最后一个之外的所有微波电路部件的插入等待，WaitOver函数用于最后一个微波电路部件设置完后插入等待时间，并直到所有等待时间到了再返回。The method of the present invention includes two setting waiting functions, one is to insert the waiting time Wait (doubleeDelayLength) function, and the other is to execute the waiting time WaitOver (double eDelayLength) function, wherein the Wait function is used for all microwave circuit components except the last one Insertion wait, the WaitOver function is used to insert the waiting time after the last microwave circuit component is set, and returns until all waiting times are up.
Wait函数功能的实现原理包括以下步骤：The implementation principle of the Wait function includes the following steps:
首先，获取当前的精确时间点；First, get the current precise time point;
然后，将当前的精确时间点加上需要等待的时间后，再获取当前线程的线程句柄，传给等待时间管理线程；Then, after adding the current precise time point to the waiting time, obtain the thread handle of the current thread and pass it to the waiting time management thread;
接下来，等待时间管理线程从线程句柄为标识的多个等待延时队列中，读取保存的最早完成等待时刻与这个时间点对比，如果最早完成等待时刻早于这个时间点则用这个时间点替代最早完成等待时刻，存入以该线程句柄为标识的队列中，否则用函数传入的这个时间点替代该线程句柄标识的最早完成等待时刻；Next, the waiting time management thread reads the saved earliest completion waiting time from the multiple waiting delay queues identified by the thread handle and compares it with this time point. If the earliest completion waiting time is earlier than this time point, use this time point Instead of the earliest completion waiting time, store it in the queue identified by the thread handle, otherwise, replace the earliest completion waiting time identified by the thread handle with this time point passed in by the function;
Wait函数执行完，传递完参数后立即返回，并不等待。After the Wait function is executed, it returns immediately after passing the parameters without waiting.
WaitOver函数功能的实现原理包括以下步骤：The implementation principle of the WaitOver function includes the following steps:
首先，获取当前的精确时间点；First, get the current precise time point;
然后，将当前的精确时间点加上需要等待的时间后得到需要延迟到的时刻值，再获取当前线程的线程句柄，将这两个参数传给等待时间管理线程；Then, add the current precise time point to the waiting time to get the time value that needs to be delayed, and then get the thread handle of the current thread, and pass these two parameters to the waiting time management thread;
接下来，等待时间管理线程从线程句柄为标识的多个等待延时队列中，读取保存的最早完成等待时刻值与这个时间点对比，如果最早完成等待时刻早于这个时间点，则等待WaitOver传入的等待时间后，即通过事件通知让WaitOver退出。Next, the waiting time management thread reads the stored earliest completion waiting time value from the multiple waiting delay queues identified by the thread handle and compares it with this time point. If the earliest completion waiting time is earlier than this time point, wait for WaitOver After the incoming waiting time, WaitOver will exit through event notification.
WaitOver函数需要实际等待足够的时间以到达最早完成时刻值。The WaitOver function needs to actually wait enough time to reach the Earliest Completion Time value.
为了更详细地说明本发明的技术方案，下面给出一具体实施例：In order to illustrate the technical scheme of the present invention in more detail, a specific embodiment is provided below:
如图2所示，在某型号微波信号分析仪中，总共有输入开关选择、YTF调谐滤波器、合成本振多环路、多级开关滤波器、其它微波电路单元等，按照传统的方式，每当设置完一个微波电路单元后，都要调用Sleep函数等待，采用本发明后，所有原来调用Sleep等待的地方都换成Wait函数调用，当执行完所有的硬件设置后，或最后一个硬件单元设置完毕后需要调用等待的地方换成WaitOver。As shown in Figure 2, in a certain type of microwave signal analyzer, there are a total of input switch selection, YTF tuning filter, synthetic local oscillator multi-loop, multi-stage switching filter, other microwave circuit units, etc., according to the traditional method, Whenever a microwave circuit unit is set, the Sleep function must be called to wait. After the present invention is adopted, all places where Sleep was originally called to wait are replaced with Wait function calls. After all hardware settings have been performed, or the last hardware unit After the setting is completed, the place that needs to be called to wait is replaced with WaitOver.
在启动仪器的测试前，要设置仪器内部的一系列微波电路硬件单元，首先设置输入开关选择，等待500毫秒，再设置输入YTF调谐滤波器，等待800毫秒，再设置本振合成环路，等待900毫秒，再设置多级开关滤波器，等待500毫秒，最后设置其它电路单元，调用WaitOver等待500毫秒后，完成仪器的设置，仪器开始返回测量结果数据。Before starting the test of the instrument, it is necessary to set a series of microwave circuit hardware units inside the instrument, first set the input switch selection, wait for 500 milliseconds, then set the input YTF tuning filter, wait for 800 milliseconds, then set the local oscillator synthesis loop, wait 900 milliseconds, then set the multi-stage switching filter, wait for 500 milliseconds, and finally set other circuit units, call WaitOver and wait for 500 milliseconds, complete the instrument settings, and the instrument starts to return the measurement result data.
时间管理线程开始执行时候的时刻为10432ms(从开机算起的时间)，每个微波部件的设置执行时间为1ms，系列参数和执行结果如表1所示：The time when the time management thread starts to execute is 10432ms (the time from power-on), and the execution time of each microwave component is set to 1ms. The series parameters and execution results are shown in Table 1:
传统方法执行时间加顺序等待时间总共需要3205ms，采用本发明后执行时间加等待时间为11233-10432＝801ms，时间只需要原来的25％，效率提高为原来的近四倍。The execution time of the traditional method plus the sequential waiting time needs 3205ms in total. After the present invention is adopted, the execution time plus the waiting time is 11233-10432=801ms, and the time only needs 25% of the original time, and the efficiency is improved nearly four times.
本发明通过设计等待时间复用，能够极大的减少微波仪器测量软件设置微波电路单元过程中的等待时间，尤其是在微波部件比较多的情况下，从而大大提高微波仪器的测试效率；测试效率提高显著，实现成本低廉，便于推广。The present invention can greatly reduce the waiting time in the process of setting the microwave circuit unit by the microwave instrument measurement software by designing the waiting time multiplexing, especially when there are many microwave components, thereby greatly improving the testing efficiency of the microwave instrument; testing efficiency The improvement is remarkable, the realization cost is low, and it is convenient to popularize.
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention.
