(Management Application for Remote Internet Experiments)

Application description

Many people are looking for a solution to remotely control a real process. For example, record webcam for tracking, turn on the heating before the arrival of the weekend, and the like. Of course today it is full of professional solutions such as GSM-based modules. However, our aim was to create application solutions, through which could be remotely controlled via the Internet experimental apparatus physical experiment. Thus, controlled trials are then called remote laboratory, which can be used for both direct instruction and independent homework for students. Nowadays, several solutions for the creation of remote laboratories, but most of them are very expensive (tens of thousands of CZK per job). Therefore our aim was to create a low-cost solution that would be useful for most of the necessary applications, achieved similar parameters as previously known solutions, but due to its poor financial performance should be able to use the authors without the necessary financial background. It is understandable that this solution is not so much "comfort" and a large part of the money saved will have a creator-developer issue in the form of their efforts.

Developed by us control applications K8055-MARIE (Management Application for Remote Internet Experiments) is an application that enables remote (Internet) management USB experimental board K8055 (see Figure 1). Universal experimental plate K8055 is a professional product of Velleman, the board has the five digital inputs (two counters with function), two analog inputs (with damping and amplification), as well as eight digital outputs and two analog outputs (both voltage and with pulse width modulated). The board is powered directly from the USB interface of the PC. From the technical point of view the K8055 board as an extension of the classic PC input-output options more than sufficient. The board is supplied in the form of an electronic kit (900 CZK) or as a ready-made module (1500 CZK). The board is delivered naturally and control software including DLL libraries for the development of custom applications.

The application K8055-MARIE has been developed (on the original control DLL) for remote control of the K8055 board. This application allows full control USB experimental boards K8055 setup ie analog and digital outputs, analog and digital load inputs, work with the parameters of the counters. Application K8055-MARIE is running on a computer that is connected K8055 board, and using web sites on the web server, you can remotely control the K8055 board. (Fig. 2).
