Abstract

The aim of this work is to design and develop a control system using SMS and WiFi technology to remotely control the outdoor security lights in large organisations. The device comprises four main units, namely: the mobile phone or a computer system, the GSM modem, the switching unit and the WiFi module. One feature that makes the developed system better than other related existing works is its ability to use two means of control. It makes use of WiFi when the operator is within the coverage area of the network of about 100 metres to the device, at no cost, otherwise it uses SMS containing certain codes to control the lamps. A SIM card is placed in the GSM modem and SMS from the transmitter are sent to that mobile number. The module is also constantly being monitored by the microcontroller unit, which in turn processes the information, extracts the message and command from the GSM modem and WiFi module respectively and then acts accordingly. Owing to its simplicity, C programming is used to programme the microcontroller. The developed device when tested with three lighting points operating on 230V power supply, gives an impressive performance with both SMS and WiFi technology. The benefit of this work is in its low-cost real-life practical application.

采用短信和WiFi技术的高效远程控制系统，用于户外安全照明应用

这项工作的目的是设计和开发一个控制系统，使用短信和WiFi技术远程控制大型组织的室外安全灯。该设备包括四个主要单元，即:移动电话或计算机系统、GSM调制解调器、交换单元和WiFi模块。使所开发的系统优于其他相关现有作品的一个特点是它能够使用两种控制手段。当运营商在距离设备约100米的网络覆盖范围内时，它会免费使用WiFi，否则它会使用包含某些代码的短信来控制灯具。将SIM卡放入GSM调制解调器中，发送器将短信发送到该手机号码。该模块还受到单片机的不断监控，单片机依次对信息进行处理，分别从GSM调制解调器和WiFi模块中提取消息和命令，然后采取相应的行动。由于其简单性，我们采用C语言编程对单片机进行编程。开发的设备在230V电源下使用三个照明点进行测试时，在短信和WiFi技术方面都表现出色。这项工作的好处在于其低成本的实际应用。
