Embodiment 1

[0038] see figure 1 , this embodiment provides a temperature and humidity acquisition and detection device inside and outside the granary, the device is used in temperature detection inside and outside the granary, and the detected data can be transmitted to the background. Wherein, the detection device includes a detection device, a measurement and control cable, a temperature and humidity measurement and control circuit, a processor, an isolation protection circuit, a communication module, a power supply module and a serial number identification module. Some of these modules can be assembled together, and a single module can also be split into multiple units with different functions.

[0039] There are multiple detection devices, and the detection devices generally use sensors. Existing sensor devices can be used as detection devices, and these detection devices are arranged inside and outside the granary, and can detect temperature information and humidity information insi...

Embodiment 2

[0064] This embodiment provides a method for collecting and detecting the temperature and humidity inside and outside the granary, which is applied to the device for collecting and detecting the temperature and humidity inside and outside the granary in Example 1. Wherein, the detection method comprises the following steps:

[0065] When performing a read operation, first open the pull-down drive pin, make the data pin output a low-level signal through the current amplification module 2, then close the pull-down drive pin and open the pull-up drive pin, and make the data pin output through the current amplification module 1 The pin outputs a high level signal, and finally turns off the pull-up drive pin, so that the data pin generates a rising edge pulse to the detection device, and the detection device replies to the current data bit state, and the processor responds by reading the state of the read data pin signal to realize the data bit read operation;

[0066]When perform...

Embodiment 3

[0068] This embodiment provides a computer terminal, which includes a memory, a processor, and a computer program stored in the memory and operable on the processor.

Description

technical field [0001] The invention relates to a detection device in the technical field of granary monitoring, in particular to a detection device for collecting and detecting temperature and humidity inside and outside a granary, and also relates to a method for collecting and detecting temperature and humidity inside and outside a granary for the detection device. Background technique [0002] In the field of grain monitoring and control, in order to ensure the quality of stored grain, relevant departments attach great importance to the storage environment. The most important indicators in the process of grain storage are ambient temperature and humidity, so a device is needed to monitor the temperature and humidity inside and outside the granary To ensure a suitable storage environment. After investigation, it is found that most of the current temperature and humidity monitoring equipment have different functions, and some only support single-channel acquisition, which ...
