Surface temperature field in-line monitoring system

Desert region is located in the north country, the natural environment is very bad, summers are hot, the surface maximum temperature as high as 70 ¡æ, the winter cold, surface temperature dropped below -30 ¡æ. The road in such an environment, the road structure will produce a lot of damage; cold and wet areas, the road subgrade deformation and damage caused by frost heave a more serious occurrence of these diseases are directly related to thermal conditions the road embankment. In order to avoid the road operator during the occurrence of disease in the design and construction of the desert highway when the road embankment should take full account of the distribution of thermal conditions.

    Many experts in-depth study of environmental factors on the road surface temperature field of mechanism and the distribution of surface temperature field and found that air temperature and solar radiation intensity affect the asphalt pavement temperature field of the main factors, both on the asphalt pavement temperature field are cumulative and lagging characteristics. Many parts of China through the measured surface temperature data and meteorological data regression analysis, set up to temperature, solar radiation intensity and depth of the road as the main input parameters of the asphalt pavement temperature prediction model.

   In order to verify the correctness of the model and design of the feasibility of building roads and road games online temperature monitoring system for real-time on the road surface temperature field data collection, monitoring, storage and analysis becomes necessary. Our highway road games online temperature monitoring system is fully able to meet this requirement, and in the actual project was able to verify its feasibility and effectiveness. Cost-effective, simple operation, easy installation to become an important feature of this product.

  

Program features:

 1. Structure is simple, easy wiring. Sensor bus with three-wire system, all sensors can be directly attached to the bus.

 2. With a communication interface can be directly connected to the computer. Module comes with RS232 Interface \

 3. Each module has an ID, multiple modules can be composed of a large network of temperature collection

Program parameters:

 1. Power Supply: 5V 1A

 2. Sensors to detect temperature range: -55-125 degrees, the measurement accuracy: 0.5 degrees

 3. Super drive module can be accessed by 64 sensors

 4. As far as detection range: 300 meters

Program Disadvantages:

 1. Must be collected with a computer connected to the data. The module itself is no display.

 2. As far as communication distance limited to 300 meters, the long-distance communication, networking required a multi-module program


The following is the product's introduction and practical application.


Software functions and features:
1, based on client / server (C / S) software model
SLET2009 system software from the server software and client software of two parts. Server Edition software is installed on the bus associated with the measurement of the computer. The client software running on the enterprise LAN to other computers. The two parts of the software have the same function: to provide online collection, monitoring, analysis, alarm, control and other functions, the software main interface shown in Figure 4

4, a powerful alarm capabilities
The system alarm, the "alarm" dialog box pop up automatically, providing the exact location of measuring point alarm, measuring point names and details of the alarm time and the channel location of measuring points on the plan turns red. If the master device is connected and on-site can be alert to respond to the corresponding action, such as alarm messages to mobile phones.
