Multi-point Soil Temperature and Humidity Recorder to Collect Forest Soil Temperature and Humidity Data
The whole system of multi-point soil temperature and humidity recorder consists of two parts, the soil temperature and humidity data acquisition subsystem and the remote monitoring and receiving subsystem, as shown in Figure 1. The system has the functions of querying, storing, regularly reporting and warning (fire or flood) of soil temperature and humidity. The on-site data acquisition subsystem consists of a data acquisition module, a CDMA module, and a power module. The monitoring and receiving subsystem consists of a server, a display control computer, and a monitoring server.
Data acquisition subsystem software mainly includes operating system migration module, main program design module and A/D conversion program design module. Because the soil monitoring requires real-time, this design will transplant the embedded operating system with better real-time to the S3C44B0X. The system is required to complete the hardware initialization of the S3C44B0X in the main function, and then initialize the various operating system modules. The operating system has a total of three task modules, namely the main task (sensor data acquisition), CDMA communications, GPS positioning and data acquisition. Among them, the main task has the highest priority level, and data collection, processing, and transmission are performed every 4 hours.
The multi-point soil temperature and humidity recorder uses the embedded processor as the core of the data acquisition subsystem to develop the monitoring program for the acquisition subsystem. Using CDMA1X network and Internet as the carrier to send data to the remote monitoring center, remote monitoring of forest soil parameters was realized. According to actual needs, the relevant modules in the system can be cut or the sensor of the acquisition subsystem can be changed. It can also be used in other fields of environmental monitoring and has a wide range of application prospects.
LED Stage Light
- Product Description
LED stage light is a new type of lamp that uses LED lamp beads as a light source for stage lighting.
LED stage light is a kind of stage lighting. With the improvement of LED technology and the decrease of cost, LED technology lights will play an increasingly important role in the stage lighting industry.
- structure
The composition of LED stage lights is similar to that of LED lighting. The main accessories are housing, LED lamp beads, secondary optical lens, LED drive power, DIP switch, heat sink, housing, mounting bracket, etc.
- Features
The performance of LED stage lights is closely integrated with LED technology, rich in colors, red, green and blue can be mixed with 16.7 million different colors. Low power, low driving voltage, high luminous efficiency, and energy saving. Safe without radiation and without ultraviolet rays. Long lifespan, the theoretical service life can reach 100,000 hours. Compared with traditional stage lamps, the price of LED stage lamps on the market in 2014 is higher.
