1, remote equipment monitoring system <br> <br> This design principle of the Internet-based remote equipment monitoring system, mainly in building equipment or industrial equipment, PLC control cabinet, intelligent routers, remote server four parts, shown in Figure 1. The building equipment can include air conditioning, lighting, etc. The main function of the PLC control cabinet is to control the opening and closing of the equipment. The role of the remote server is to store the equipment's real-time monitoring information so that the user can view the server in real time through the computer, tablet or mobile phone. Another function is to push an alert message to the user terminal when it is detected that the device data is abnormal. 
2, intelligent router design <br> <br> paper will use the Cortex-A8 embedded board to follow an intelligent router. The software design of the intelligent router mainly includes embedded linux operating system, web server lighttpd, database mysql, modbus protocol and monitoring device application program. The main hardware on the smart router includes the processor, 3G module, Ethernet port, serial port and SD card slot.
2.1 Data Acquisition <br> <br> to herein as the modbus protocol device real-time data transmission, to a serial port and an Ethernet data acquisition mode, the final data transmission through the Ethernet or 3G network to the server, the data stored on the server In the database. The data obtained from the device will all be stored in the SD card of the smart router, and the data uploaded to the server needs only a key part of it. When you need to get all the detailed data, you can also remotely log in to the smart router for viewing. This will not only greatly reduce the capacity of the server to store data, but also greatly reduce the bandwidth required by the client.
2.2 Main Software Description Open Wrt is an open source linux distribution with excellent extensibility and powerful networking components. It is suitable for all types of embedded devices and routing devices. Open Wrt's file system is writable, meaning that users can freely add what they need without recompiling the entire system firmware. Lighttpd is an open source web server software designed for high-performance websites with features such as good performance, low memory overhead, rich modules, and very low CPU usage. Lighttpd is designed to provide a site server environment that is well-suited for high-performance websites, and is compatible, fast, secure, and flexible.
3, part of the system software 3.1 add devices to be monitored for each new device to be monitored <br> <br> by its own device name, device ip, device id, device port uniquely determined, and the system will give the device to generate A unique hash value. In data monitoring, the system also stores the hash value as the unique identifier of the device. The purpose of this is to make it possible to modify the device information in the future without modifying too many data tables. Under normal circumstances, in order to better understand the operating status of a device, it is often more than just monitoring one device point of the device, but multiple, and each monitored point may need to be different depending on the sensitivity of its own data. Data monitoring speed. In order to facilitate the user to add new equipment and various information of equipment points and alarm points that need to be monitored, the system provides the user with the tftp transmission mode, so that the user can directly transmit the monitoring file with the specified format to the intelligent router. The user only needs to fill in the relevant file name and tftp server ip when adding a new device.
3.2 Alarm processing
The monitoring system designed in this paper is applied to most of the monitored devices. In addition to monitoring the switching status of a light bulb, such as a light bulb, it is necessary to monitor such numerical values ​​as temperature and humidity. Compared with the numerical value, the switch quantity will be relatively simple to monitor. The monitoring of the numerical value is slightly more complicated because the value of the numerical value is smooth, so that the value may fluctuate up and down from the alarm value in the case of external disturbance. Eventually the system will appear to alarm without warning. In order to solve the above problem, this paper sets a buffer for the numerical alarm value. When the status is no alarm, the alarm will be activated only when the value of the numerical value is greater than the value of the alarm point. When the status is an alarm, the alarm is canceled only when the value of the numerical value is smaller than the value of the alarm point. It mainly includes data acquisition programs and alarm programs. In addition, considering that the data may be subject to data jitter due to external interference, processing is only given when the data value reaches the state transition area and continues for a certain period of time in the area.
Conclusion <br> <br> This article focuses on the basic principle of the system work, and introduced the design of hardware and system software is the main part of the circuit system in detail. Compared with traditional IT operation and maintenance services, Internet-based IT operation and maintenance services have more advantages. With the continuous deepening of Internet applications, smart routers will be more widely used and developed. The design of remote monitoring systems in this paper will also play a positive role and role.
[Design Solution] Building Device Monitoring System Based on Intelligent Router
At present, most of the monitoring of building equipment is based on manual inspections. For example, for some equipment that needs real-time monitoring, maintenance personnel are usually placed next to the equipment. Of course, the drawbacks of this model are also obvious. It not only consumes a lot of human resources, but also greatly increases the cost of monitoring. The current on-line equipment fault monitoring system mostly adopts the acquisition card and PC mode. The acquisition card is responsible for collecting data, and the PC is responsible for data processing and transmission. This kind of system is bulky and expensive, and is not suitable for applications where the production equipment is dispersed and the work environment is harsh. In order to solve these problems, this paper applies intelligent router related technology and Internet technology to the design scheme of equipment monitoring system, making the equipment failure detection system have remote monitoring function.
