Description

A remote intelligent environment monitoring device for greenhouses based on GSM network

technical field

The utility model relates to a temperature control device, in particular to a GSM network-based remote intelligent environment monitoring device for greenhouses.

Background technique

With the popularization of greenhouse technology, the number of greenhouses continues to increase. For vegetable greenhouses, the most important management factor is the control of temperature, humidity and CO2 concentration. If the temperature and humidity are too low, vegetables will freeze to death or stop growing. CO2 If the concentration is too high or too low, the efficiency of photosynthesis of vegetables will be reduced, causing the growth of vegetables to be too slow or even stop growing.

The traditional temperature control is to hang a thermometer inside the greenhouse, and workers adjust the temperature in the greenhouse according to the read temperature value. Manual control alone is labor-intensive and prone to errors. Temperature control in greenhouses becomes a difficult problem. Now, with the improvement of the scale of the agricultural industry, for a large number of greenhouses, the traditional temperature control measures have shown great limitations. In recent years, the number of greenhouses is increasing at an alarming rate. In order to improve production efficiency, the influence of humidity and CO2 concentration on the growth rate of vegetables has gradually attracted the attention of managers.

For this reason, in the management of modern vegetable greenhouses, there is usually an automatic temperature and humidity control system to control the temperature, humidity and CO2 concentration of the greenhouse to meet the needs of vegetable growth. However, these devices are often expensive, cumbersome, poor in mobility, and have no remote alarm function and remote real-time query function. This is the situation when the production is severely reduced or completely lost due to sudden changes in the environment in the greenhouse, which poses a great obstacle to the timely rescue work of the managers.

GSM mobile phone communication module, the GSM mobile phone module mainly communicates with the CPU through the serial port of the AT command, transmits the received voice command and information command to the CPU in the AT command format, and sends the AT command transmitted by the CPU to the CPU in the corresponding format. After the manager's mobile phone, CPU processes and judges the parameters collected by each sensor, it controls each generator through the control module to realize the automatic control function. At the same time, the administrator can also control the control module by editing information.

If a certain parameter is not in the appropriate range Inside, the utility model will automatically open the generating device of this parameter, and close the generating device after the parameter in the greenhouse reaches the preset range.

At the same time, when the greenhouse manager is not in the greenhouse, the GSM automatic alarm function can also be turned on, and the alarm range of temperature, humidity and CO2 concentration and the manager's mobile phone number can be set. If the weather changes drastically, the temperature drops suddenly, and a certain parameter in the greenhouse exceeds the alarm range set by the manager, the device will send an alarm message to the manager's mobile phone number, which is convenient for the manager to rescue in time and reduce the loss to minimum.

The utility model uses the widely used GSM network as the remote communication channel, which not only greatly saves the cost, but also greatly improves the reliability of the device.
