A supervisory unit with an indicator light and its realization method

Abstract

The invention discloses a supervisory unit with an indicator light and an implementation method thereof. The supervisory unit comprises: a battery, a temperature and humidity acquisition module with an indicator light, a temperature sensor switch, a pressure switch module, and fourth to seventh field tubes; The output of the pressure switch module is connected to the grid of the fifth field transistor; the grid of the fourth field transistor is connected to the temperature and humidity acquisition module; the grid of the sixth field transistor is connected to the drain of the fourth field transistor; The drain of the tube is connected to the gate of the seventh field tube, and the connection lead is connected to the input of the temperature and humidity acquisition module; the temperature and humidity acquisition module is connected to the peripherals through wireless; the temperature sensor switch is connected in parallel with the switches of the sixth and seventh field tubes The back string is connected to the power path of the battery and the temperature and humidity acquisition module; the method is that when the temperature and humidity acquisition module responds to the interrupt application sent by the pressure switch module through the output of the fifth field tube, it is determined that the warehouse is being turned over or the grain is being stored or the grain is stolen, and upload There is output information to the peripheral device, and the identification code returned is identified. If it is the identification code of turning bin / grain release, the indicator light is turned on.

Description

technical field [0001] The invention belongs to the technical field of granary safety, and in particular relates to a supervisory unit with indicator lights at the end of a granary monitoring and management system and its realization method. Background technique [0002] As we all know, during the grain storage process, it is easily affected by temperature, humidity and other factors, and problems such as heat generation, mildew, and pest breeding may occur. In order to reduce the loss during the grain storage process and ensure the quality and quality of the grain, the granary monitoring and management system takes corresponding measures to cool down, dehumidify, Or turnover processing. At present, the granary monitoring and management system: according to the specific conditions of temperature and humidity uploaded by the sensor device of the terminal node, it can be automatically completed when cooling and / or dehumidification is required, but manual participation must be...

AI Technical Summary

Problems solved by technology

It is convenient to supply power to the node of the wired temperature and humidity sensing device, but it is inconvenient to install it in the grain pile; while it is convenient to bury the node of the wireless temperature and humidity sensing device in the grain pile, but the power supply must be wireless and / or battery powered, and No battery power supply, if the temperature and humidity exceed the limit, it cannot be monitored in real time, that is, it cannot be uploaded to the granary monitoring and management system

The wired temperature and humidity sensing device can not only facilitate the regular inspection of the granary monitoring and management system, but also facilitate the real-time upload of temperature and humidity exceeding the limit to the granary monitoring and management system during the inspection period, because the wired temperature and humidity sensor The power supply of the sensing device is convenient, so the temperature and humidity sensing device in the wired mode can be in the live working state all the time, but the node of the temperature and humidity sensing device in the wired mode is not convenient to be installed in the stacking granary; the temperature and humidity sensing device in the wireless mode The sensing device node can facilitate the regular inspection of the granary monitoring and management system, and the wireless temperature and humidity sensing device node is located in the stacking granary, which is more convenient than the wired temperature and humidity sensing device node, but the granary monitoring and management system is not in the inspection. During the inspection period, if the temperature and humidity exceeds the limit, it needs to be uploaded to the granary monitoring and management system in real time. The node of the wireless temperature and humidity sensing device must have its own power supply battery. Because the power of the battery is limited, it must be considered in the state of energy saving. If the management system is not in the inspection period, if the temperature and humidity exceed the limit, it will be uploaded to the granary monitoring and management system in real time, and the problem of convenient battery replenishment needs to be considered

After investigation, there is still no good solution to solve the energy saving problem of the wireless temperature and humidity sensing device with temperature and humidity overrun uploaded to the granary monitoring and management system in real time, and to solve its battery power replenishment problem, because once the wireless method The temperature and humidity sensing device is embedded in the stacking granary, which is inconvenient to take out. It is convenient to take out the temperature and humidity sensing device when the bin is turned over or the grain is put out.
