A remote temperature monitoring system includes a temperature monitoring device and a remote monitoring platform. The temperature monitoring system uses a temperature acquisition sensor to process collected temperature data in a single-chip microcomputer, and then the processed data information is transmitted to a computer by the single-chip microcomputer. Monitoring software is installed in the computer. After the software obtains the data, the data are parsed, and then a temperature-time map is presented in a visual interface. At the same time, the temperature monitoring device also transmits the parsed data to the remote monitoring platform, thereby realizing remote monitoring of temperature. The system integrates multi-channel acquisition, remote monitoring, timed temperature measurement, real-time mapping, data storage, temperature alarm and other functions into one.

A system for network load balancing includes multiple access points (AP), multiple entertainment devices and a DHCP server. Each AP is connected to one entertainment devices and the DHCP server, each entertainment device includes a DNS server and a web server, and all DNS servers store and parse the same domain names. When the AP receives an access request of a wireless terminal, the DHCP server designates a DNS server in an entertainment device connected to the AP as a DNS server for the wireless terminal. When the AP receives a domain name parsing request of the wireless terminal, the designated DNS server parses the domain name into an IP address of a web server in the entertainment device including the DNS server. When the AP receives a web access request of the wireless terminal, the designated web server responds to the web access request via the AP.
