We present a temperature monitoring and warning system, which is based on wireless communication technology and applied in train switchgear in this paper. The system is consists of three parts, including wireless temperature detection module, inter-vehicle transmission networks module and remote monitoring server. The switchgear contact temperature data are collected via the wireless temperature detection module and exchanged in inter-vehicle wireless networking by Zigbee modules. Then the temperature of train switchgear cabinets can be monitored remotely through the GPRS wireless communication.

“…ZigBee. The most employed protocol in WSNs' applications is the ZigBee protocol [12,18,[20][21][22][23][24]. This protocol has a number of desirable characteristics for WSN applications as, for example, low power consumption and low cost.…”

“…The MiWi protocol [26], developed by Microchip, is an alternative for small networks with at most 1000 nodes. Theoretically, a ZigBee network can contain up to 65536 nodes although, in practice, it is not recommended having more than 3000 nodes in a single network [23]. Another factor that limits the size of MiWi networks is the maximum number of hops allowed (i.e., four hops).…”

This paper presents a theoretical study for verifying the impact of using smart nodes in motor monitoring systems in industrial environments employing Wireless Sensor Networks (WSNs). Structured cabling and sensor deployment are usually more expensive than the cost of the sensors themselves. Besides the high cost, the wired approach offers little flexibility, making the network deployment and maintenance a complex process. In this context, wireless networks present a number of advantages compared to wired networks as, for example, the ease and speed of deployment and maintenance and the associated low cost. However, WSNs have several limitations, such as the low bandwidth and unreliability, especially in harsh environments (e.g., industrial plants). This paper presents a theoretical study on the performance of WSNs for motor monitoring applications in industrial environments, taking into account WSNs' characteristics (i.e., unreliability and communication and processing latency). The results obtained through mathematical models were analyzed together with experimental results, and it was demonstrated that employing intelligent nodes with local processing capabilities is essential for the applications under consideration, because it reduces the amount of data transmitted over the network allowing monitoring even in scenarios with high interference rate, paying off the extra latency resulting from local processing.

“…Zig8ee operates in the unlicensed radio frequency (RF) bands -868, 915 and 2400 MHz. These three bands provide a total of 27 channels with RF data rates of 20, 40 and 250kbps, respectively, and it is sufficient for monitoring wild substation [4,5]. The 2.4 GHz band is widely used because it is unlicensed worldwide has the highest data rate with more channel options.…”

In recent years, with the transformer substations basically unattended, a new topic for the security of power equipments and electric power lines is presented. Many alarm systems based on ac high-voltage grid, electronic pulse fence or infrared electronic fence have been installed in substations. In this paper, we propose an intelligent anti-theft alarm system based on laser fence and wireless communication network technology. Once occlusion of the laser beams occurs, it will transmit alarm information with accurate location to the control center through ZigBee network, and then send short messages to the defender's phone by GPRS. Moreover, the on site searchlights could be remotely controlled by SMS with GPRS network. The architecture and implementation of the system is described in detail. Practical results show that our system is high-security, low-power and low false-negative compared with the conventional anti-theft systems.
