Monitoring unit capable of acquiring act of theft, and implementation method thereof

Abstract

The invention discloses a monitoring unit capable of acquiring act of theft, and an implementation method thereof. The unit comprises a battery, a temperature and humidity acquisition module with an indication lamp, a temperature sensitive switch, a pressure switch module, a fourth field tube, a fifth field tube, a sixth field tube and a seventh field tube; an output of the pressure switch is connected with a grid of the fifth field tube; the grid of the fourth field tube is connected with the temperature and humidity acquisition module; the grid of the sixth field tube is connected with a drain of the fourth field tube and one end of the temperature sensitive switch, and the other end of the temperature sensitive switch is connected with a cathode of the battery; the drain of the fifth field tube is connected with the grid of the seventh field tube, and a wire is led to an input of the temperature and humidity acquisition module from a connection line thereof; the temperature and humidity acquisition module is connected with peripherals wirelessly; and the sixth field tube and the seventh field tube are connected in parallel and further connected to a power path of the battery andthe temperature and humidity acquisition module in series. The method is characterized in that the temperature and humidity acquisition module confirms that storehouse turning or grain discharging orgrain stealing happens currently when the temperature and humidity acquisition module responds to an interruption application sent by the pressure switch module via the fifth field tube, uploads output information to the peripherals and identifies return identification codes; and if the return identification codes are storehouse turning / grain discharging identification codes, the indication lampis turned on.

Description

technical field [0001] The invention belongs to the technical field of granary security, and in particular relates to a monitoring unit capable of acquiring theft behavior at the end of a granary monitoring and management system and a realization method thereof. 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 ...

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.
