The computer will store the received data and compare it with the standard values set by the system. If the field value exceeds the standard value, the system will alert the management personnel, and will automatically control the fan and other equipment for cooling treatment.
When the label is placed in the grain warehouse, the label will collect information on the temperature and humidity in the grain warehouse from time to time; the data will be automatically sent to the reader; the reader and the data will be transmitted to the reader through the serial port or network port. Computer; The computer will store and compare the received data. The system will drop out the set standard value and compare it with the collected field data. When the temperature and humidity of the site is higher than the standard value, the computer will pass through its I/O control port. , control the on-site fan to start cooling; at the same time the computer will always pass the sensor signal, monitor the temperature and humidity in the granary, knowing that the set value is reached. Example: Each temperature and humidity sensor is provided with an ID number. The ID number is composed of 24 digits of letters and numbers. It can realize unlimited serial number combination and can realize globally unique ID number; ID number of each tag The location is corresponding to this, this can be in the system when the database is built, the location is bound in the ID number of the information. That is, when the system reads the ID number with the serial number "1234567", the system will know that the label is in: No. 6 warehouse, the third temperature and humidity label, the specific location is: height 6.5 meters; distance A wall 3.2 meters; 6.2 meters away from the B wall; if the temperature measured by the label is high, the system will know the specific location for easy adjustment. When the tags measure the data in the field, they will use their own built-in power supply to activate the wireless transceiver module in the SCM and send the data wirelessly. The transmission distance can be up to 1000 meters. The sending distance of the tag can be modulated according to the specific distance of the site. Can be adjusted between 10 and 1000 meters. At the same time, the label is transmitted using electromagnetic waves and has a strong penetration force. Even if the label is implanted in the grain, it can be accurately read.
The tag transmits the data to the reader. The reader interprets the data and sends it to the computer through the serial port 485 bus. The reader-writer is mounted outside of the granary and transmitted to the computer via cable. This can save space for a limited space granary, while avoiding the cumbersome cabling problem.
