Complex electrocardio figure display routine operates in the host process of host computer.User's control flow that shows and flow for displaying are all carried out in the message circulation of mastery routine.
The switch window action that the execution of complex electrocardio figure flow for displaying starts by the user causes, triggers by the message circulation.It is not directly to be triggered by the message circulation that the program of the closed portion of flow process is carried out, but is caused by other window performance of switching of user, finishes by calling indirectly.
The demonstration of complex electrocardio figure refreshes two sources, and one is that system's routine refreshes, and one is that the intervalometer triggering refreshes, and they all circulate by message and trigger.
Other operation of flow process is all carried out in the time period between start-up operation and end operation, can operate with arbitrary number of times and order.
Complex electrocardio figure flow for displaying is a sub-process that is included in the control flow, though also in host process, move, because its importance, so with its independent description.
Because the flow for displaying content is more, the logic discrimination relation is too loaded down with trivial details, is difficult on the little page or leaf paper to express, so omit in flow chart, each inside, flow process unit all can be regarded as and is had logic discrimination.
As shown in Figure 8, signal acquisition process program host computer flow process (mastery routine):
Step h-1: beginning;
Step h-2: equipment, file handle initialization;

As Figure 10, digital signal acquiring plate (slave computer) flow process is as follows:
Step f-1: beginning;
Step f-2: response the resetting of host computer, transmission command;
Step f-3: reset?
Step f-4: be; Reset operation; Not; Buffered data packing back is sent by USK; Return step f-2.
Step g-1: beginning;
Step g-2: signal carries out AD conversion and circular buffering; This step cycle is until finding FIFO;
Step g-3: FIFO is gone to step f-4 the buffered data packing is back by the USK forwarding step.
Digital signal acquiring plate (slave computer) flow process Figure 10 is the program circuit on electrocardiosignal hardware collection plate, and its effect is to carry out being transferred to host computer behind the digitized with gathering the analogue signal of coming.Host computer is the stronger computer of disposal ability, the data of sending here can be carried out more powerful subsequent treatment.
Whole flow process is to constitute by two little handling processes are collaborative, and one is USK communication process flow process, and an AD conversion process flow process because flow process is fairly simple, just no longer is described in detail.
Host computer handling process Fig. 8, the 9th, the handling process of electrocardiograph master computer, the data that host computer receives from USK equipment by the acquisition of standard device IO function, carry out a series of subsequent treatment then, finish functions such as filtering, storage, demonstration, thereby finish the acquisition function of ECG data.
Flow process is finished by a plurality of processes, for the ease of understanding, the flow process of two subprocess is integrated into a sub-process flow chart, therefore can regard collecting flowchart by two processes as and finish.A host process and a subprocess.
Host process mainly is responsible for the response of user's operation is handled, as the startup and the end of gathering, the intermediary various adjusting controls of gatherer process etc.Cyclic part in the flow process in reality realizes, is to adopt the circulate round robin of the program of finishing of the message of Windows program frame.
The subprocess flow process mainly is responsible for correction, filtering, deposit, the display process of dynamic data, it is an in-process systemic circulation flow process, the control of flow process is controlled realization by the state variable of the overall situation, and these state variables are that the flow process by host process changes.Subprocess itself is also created by host process, and it was created in second step of host process.
As mentioned above, embodiment of the present utility model is explained, but as long as not breaking away from inventive point of the present utility model and effect in fact can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the present utility model.
