The invention discloses a multi-functional temperature detection system based on wireless transmission. The system is characterized in that the output end of a temperature sensor is connected with the signal input end of a single-chip microcomputer; the single-chip microcomputer is in communication connection with a radio frequency emitting module; the radio frequency emitting module adds lead codes and CRC check bytes to a valid data packet stored in a valid data register, and sends the processed data packet to a radio frequency receiving module; the radio frequency receiving module carries out detection on carrier wave receiving the frequency and the address of the data packet, and if the carrier frequency and the address of the data packet are matched with preset data, receives the data; the radio frequency receiving module carries out processing on the received data packet, and transmits the processed data to a processor; and the processor carries out analysis on the received data and displays and stores the temperature data to a PC. The system has the advantages of low cost, good stability and high automation degree.
Description
technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a multifunctional temperature detection system based on wireless transmission. Background technique [0002] With the rapid development of microelectronics technology, sensor technology, embedded technology and communication technology, data acquisition and detection systems have been widely used, and there are more and more instruments used to detect various parameters. There are various types of these instruments, and the distribution is often scattered, and the workload of real-time data collection by these instruments is also increasing. How to collect these discrete data with high efficiency and low cost is an urgent scientific and technological problem that needs to be solved. For many testing sites, due to the wide range of testing and the variety of testing objects, a lot of manpower and material resources are needed for equipment maintenance and te...
