Description

Technical Field

[0001] The present application relates to the technical field of seedling raising equipment, and in particular to a seedling tray with temperature and humidity detection functions. Background Art

[0002] In crop planting technology, seedling cultivation is an important link. The growth of seedlings affects the yield of crops in the later stage. In the seedling cultivation link, temperature and humidity are two important factors affecting the growth of crop seedlings. Therefore, it is necessary to monitor the temperature and humidity in the seedling cultivation link.

[0003] In the prior art, the detection of seedling temperature and humidity mainly relies on the planting experience of farmers, which has low accuracy. Another method is to monitor the temperature and humidity in the seedling greenhouse through fixed equipment such as environmental detectors, but the monitoring result is not to monitor the temperature and humidity of the land where the seedlings are planted, so the monitoring result is not accurate enough. In some large-scale crop planting sites, detection instruments are buried in the land of seedlings for temperature and humidity monitoring, but these instruments usually need to install batteries or connect circuits, which are complicated to operate and have high management costs, and are not suitable for large-scale planting of crops.

[0004] Therefore, the inventor needs to design a new seedling tray with temperature and humidity detection function to overcome the above problems. Summary of the invention

[0029] Embodiment 1:

[0030] like Figures 1 to 4As shown, a seedling tray with temperature and humidity detection functions includes a seedling tray body 1, on which a passive sensor box 2 is fixedly arranged, and the passive sensor box 2 includes a plurality of groups of sensor probes and sensor tags electrically connected to each other, the sensor tags are located inside the passive sensor box 2, and the sensor probes are inserted in the inner cavity of the seedling tray body 1; the sensor probes include a temperature probe 3 and a humidity probe 4, and the sensor tags include a temperature tag 5 including a temperature tag 5 and a humidity tag 6; the temperature probe 3 and the temperature tag 5, and the humidity probe 4 and the humidity tag 6 are electrically connected through a wire 7; a slot 8 is fixedly arranged in the inner cavity of the seedling tray body 1, and the passive sensor box 2 is inserted in the slot 8; the passive sensor box 2 also includes a box body 9, the wire 7 passes through the box body 9 and a sealing mechanism is arranged between the wire 7 and the box body 9; and also includes a digital reader and writer, and the digital reader and writer are electrically connected to each other through a wire 7. The sensor tag is wirelessly connected; when working, before planting the seedlings on the seedling tray, the passive sensor box 2 is installed in the slot 8 of the seedling tray body 1, wherein the temperature tag 5 and the humidity tag 6 are located inside the box body 9, and the temperature probe 3 and the humidity probe 4 are located outside the box body 9. When the seedling tray body 1 is filled with soil and the seeds are planted, the soil covers the temperature probe 3 and the humidity probe 4 for detecting the temperature and humidity of the soil. When it is necessary to detect the temperature and humidity of each seedling tray, the worker operates the reader to send out a radio frequency signal. When the signal is received by the antenna inside the sensor, it is transmitted to the built-in microchip of the sensor and the microchip is activated to process and analyze the signal. The chip obtains the temperature or humidity value detected by the probe through the wire 7 and stores it in the chip. The activated chip transmits the stored data to the reader, and the reader is transcribed into the database through WIFI, Ethernet, USB or any other method to complete the information exchange. When the worker is using it, the reader can be installed on a trolley or other device. The worker only needs to walk in front of the seedling tray with the reader and operate the reader to send a signal to complete the collection of temperature and humidity information of the corresponding seedling tray. In this embodiment, the temperature tag 5 and the humidity tag 6 can be a label of model 22EVAL01-Hydro-H402 produced and sold by Shenzhen Ruichi IoT Technology Co., Ltd., which realizes information exchange through RFID (Radio-Frequency Identification) technology.

[0031] This embodiment uses passive identification technology. There is no need to install batteries or connect circuits inside the seedling tray. It is relatively simple to install, relatively stable and reliable when working, and has low management costs. It is suitable for large-scale seedling cultivation and also for random inspection of seedling temperature and humidity. It should be noted that in addition to detecting temperature and humidity, staff can also detect other items according to needs, such as salinity, etc., by simply installing salinity labels and salinity probes.

[0032] The sealing mechanism includes a sealing ring 10 arranged on the wire 7; a plurality of water seepage holes 11 are opened on the seedling tray body 1, and a plurality of reinforcing ribs 12 are fixedly arranged on the outer wall of the seedling tray body 1; during operation, since the growth environment of the seedlings has more moisture, sealing measures need to be taken to prevent moisture from affecting the temperature label 5 and the humidity label 6; the water seepage holes 11 are used for the soil in the seedling tray to absorb moisture or nutrients, and the reinforcing ribs 12 are used to strengthen the strength of the seedling tray to prevent the seedling tray from being hit and causing damage to the passive sensor box 2.

[0033] Embodiment 2: Not shown in the figure, the difference between this embodiment and embodiment 1 is that the passive sensor box 2 and the seedling tray body 1 are provided with mutually matching buckles. When working, the passive sensor box 2 is fixedly installed by the buckles. Compared with embodiment 1, the installation method of this embodiment is tighter, but the manufacturing difficulty is relatively higher.

[0034] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
