根据时间间隔发送AT指令 [英] Sending AT Command based on Time Interval
问题描述
大家好，我真的要对codeproject表示感谢，因为它确实帮助了我很多时间.
------这是我的问题-------
我被分配了一项任务，以设计一个Web应用程序，该应用程序将向GSM/GPS调制解调器发送一个AT命令，以请求其位置".根据用户规范(例如，每30分钟或1小时或每天一次的请求调制解调器位置)来处理请求
所以这就是我的库存，我该如何实施.这是界面外观的图像. (对不起，我无法粘贴图像)
---两个单选按钮----
---两个日历控件，其格式属性设置为TIME ---
---一个文本框，它将基于calander控件的值来计算间隔---
---一个基于文本框控件的时间间隔请求调制解调器位置的按钮控件----
请问我该怎么做.(问题是如何始终在每个选定的时间间隔内执行AT命令)(一位朋友建议我应该创建一个.dll文件来实现AT命令，并在按钮控制时调用它点击)
欢迎大家的任何帮助.
Hello Everyone, I really want to say a big thanks to codeproject because it has really help me big time.
------ HERE IS MY QUESTION -------
I was assign the task to design a web application that will send an AT command to a GSM/GPS modem requesting for it Location. The request is processed based on users specification like (Request Modem Location Every 30 Minutes or 1 Hour or Once a day)
So this is where i''m stock, How can i implement it. Here is an image of what the interface will look like. (Sorry i am unable to paste the image)
---Two radio button ----
--- Two Calender Control with it''s Format Properties set to TIME---
--- A Text Box that will calculate the interval based on the value of the calander control ---
--- A Button Control to Request For the Modem Location based on the interval the Text Box control----
Please how can i do it.(The Problem is how to always execute an AT Command in every time interval selected)(A Friend gave an advice that i should create a .dll file for implementing the AT Command the Call it when the Button Control is click)
Any Help from you guys is welcome
推荐答案
，您必须编写一个窗口服务，该服务将检查日期时间和时间间隔，并按AT指令进入GSM/GPS模型.
you have to write a window service which will check the datetime and interval and hit the AT Command to your GSM/GPS Model.
您无法从Web应用程序执行计划任务.相反，您需要编写一个桌面应用程序并使用Windows Scheduler以所需的间隔运行它，或者您必须编写一个Windows服务，该服务仅位于内存中并自行执行其预定的处理.我会选择Windows服务，因为即使没有用户登录，它也可以运行.
You can''t perform a scheduled task from a web application. Instead, you need to write a desktop app and use the Windows Scheduler to run it at the desired intervak, or you have to write a Windows service that will simply sit in memory and perform its scheduled processing on its own. I would go with the Windows service because it can run even without a user logged on.
