The temperature and humidity monitoring system for vegetable greenhouses developed by Chuangyi Technology is an intelligent temperature and humidity monitoring system specially developed for vegetable growing greenhouses, which can automatically monitor indoor temperature and humidity. This solution combines the characteristics of vegetable cultivation greenhouses and adopts temperature and humidity sensors to overcome the instability, large errors, easy interference, and the need for regular calibration of traditional analog temperature and humidity sensors. The instrument has accurate measurement data and high accuracy. With stable operation and reliable quality, it has broad application prospects in vegetable greenhouses.
1. What is the system made of? (What?)
The system consists of the following parts:
electronic label

The 2.4G long-distance CY-TAT-202 temperature sensor electronic tag produced by Chuangyi Technology. CY-TAT-202 resistance temperature coefficient of CY-TAT-202 is large, sensitive in induction, high resistivity, small component size, and the resistance value changes with temperature changes basically in a linear relationship. Within the temperature measurement range, the physical and chemical properties are stable and long-term recovery. Good presentability, high measurement accuracy, and effective identification distance up to 0-80m. In addition to the functions of identification and positioning, the temperature sensing electronic tag can also obtain real-time temperature data through the temperature sensing device. And the temperature data of the monitored object is transmitted to the monitoring management system through the electronic tag, so as to realize the temperature warning during the monitoring process. The product’s leading technology, all-industrial design and outstanding features enable it to provide a brand-new detection concept in cold chain, medical, warehouse management, power failure detection and other places. The effective identification distance is 80 meters, and it is widely used in various applications. Kind of field.
Card reader

Place the electronic tags produced by our company and the corresponding card reading equipment in the vegetable greenhouse. The label will collect the temperature and humidity information, such as the temperature, humidity and humidity in the vegetable greenhouse, and send the information wirelessly, so that the card reader installed nearby can receive the information, and will receive the information. The received information is transmitted to the host of the monitoring warehouse. If the current temperature and humidity of the greenhouse is not conducive to the growth of vegetables, the host will output various alarms in the manner specified by the user to remind the greenhouse administrator to make corresponding operations, so as to realize the management of the aquatic product processing process.
After the monitoring system is installed, the operator can operate the heating, ventilation and other equipment in the greenhouse based on the real-time temperature and humidity data of the sensor, which effectively solves the shortcomings of the high operating cost and high energy consumption of modern intelligent multi-span greenhouses. The monitoring system can also set alarm values according to vegetable growth conditions, and alarm when the temperature and humidity are abnormal to remind the staff to pay attention. This system is waterproof and dustproof, and can be operated in high humidity and high temperature environments such as greenhouses for a long time. And adopt wireless transmission technology to ensure the stable transmission of signals in multi-steel structure buildings such as greenhouses.
2. What are the advantages of the system? (Why?)
1) This system is a fully digital solution, and the digital signal output by each temperature probe is directly networkable.
2) Due to the use of advanced digital temperature sensors, this scheme is wired according to the network, which is convenient and economical. In theory, the entire wiring requires only one sensor bus, and no one-to-one corresponding sensor wires are required. The temperature sensors are all high-precision digital sensors.
3) Because the output of each temperature probe is directly networkable digital signal, the attenuation of the signal transmission process will not affect the accuracy of the system, and the transmission distance is long. Each outlet “one-wire bus” can be connected to multiple temperature probes. 200M, greatly reducing the number of cables in the system, improving the stability and anti-interference of the system. This is something that the traditional temperature inspection instrument cannot do, because the traditional inspection instrument transmits analog signals, and its effective transmission accuracy decreases as the distance increases.
4) The acquisition module automatically recognizes the sensor type and quantity, and is convenient for configuration and expansion. The installation position of the module and the number of modules used can be appropriately selected according to the on-site installation conditions in order to reduce the cost.
5) The display and alarm module is a professional design for monitoring the temperature of the processing and storage environment in the aquatic industry. It has the functions of on-site display and over-limit alarm. It can also be connected to the computer of the quality assurance department for real-time detection and recording. At the same time, our temperature inspection instrument is designed according to the harsh environment of aquatic product processing, using high-reliability aviation plug-ins, and moisture-proof and dust-proof design, which makes the equipment more reliable and longer life. Our temperature reading module can be placed in any need The reading environment is generally placed in the ammonia room that controls the temperature according to the needs of regular users, and the software can be installed on any supervisory computer to realize the separation of temperature data observation control and supervisory records, and the distance between the computer and the instrument where the software is installed It can exceed 1000 meters, which is very advantageous.
The patrol instrument can carry out the temperature detection and recording of multiple factories according to the needs of customers. A monitoring computer can complete the temperature supervision of all work, production and storage environments, making management simple.
6) Using configuration software technology based on win98/2000/NT/XP platform, according to different customer needs, it is convenient and fast to generate personalized man-machine interface suitable for customer needs.
7) Standardized bus design, which can easily expand control and other functions and interconnect with other systems.
Three, summary
Due to the superiority of this system, it can be widely used in vegetable greenhouses, which greatly reduces the management difficulty of the greenhouse, and has applications in many vegetable greenhouses.
