Abstract

A method and system for monitoring the temperature and humidity of warehouses are disclosed. The method includes: installing a detecting module in a cartridge, transporting the cartridge to a plurality of storages of the warehouse by a transmission assembly so as to measure the temperature and humidity of each of the storages by the detecting module, transmitting the measured results to a control unit by a wireless network, and dynamically monitoring the temperature and humidity of the warehouses according to the measured results by the control unit. The method and the system not only control and adjust the temperature and humidity of each of the storages of the warehouses in time, but also reduce detection cost.

Claims

1. A method for monitoring temperature and humidity of warehouses, comprising;

installing a detecting module in a cartridge;

transporting the cartridge to a plurality of the storages one by one by a transmission assembly so as to measure the temperature and humidity of each of storages by the detecting module, wherein a shape of the cartridge is configured to be the same with the storage such that the cartridge is arranged within the storage;

transmitting the measured results to a control unit by a wireless network;

a dynamically monitoring step comprising adjusting the temperature and the humidity of the current storage to be within a predetermined threshold range upon determining the temperature and the humidity of the current storage is not within the predetermined threshold range, and transporting the cartridge from the current storage to another storage to be measured upon determining the temperature and the humidity of the current storage is within the predetermined threshold range;

wherein the detecting module is configured within the cartridge, and the detecting module comprises a temperature-humidity sensor, an analog to digital converter (ADC), a wireless local area network (WLAN) serial service device, and a power supply that are electrically connected;

wherein the power supply supplies power to the temperature-humidity sensor, ADC, and the WLAN serial service device;

the temperature-humidity sensor measures the temperature and humidity of the storages and transmits the measured results by simulation signals to the ADC;

the ADC transforms the simulation signals to digital signals and transmits the digital signals to the WLAN serial service device;

the WLAN serial service device transmits the digital signals to the control unit by wireless transmission;

wherein at least one wireless base station is arranged within the warehouse, and a forwarder is arranged between two warehouses so as to establish the wireless network.

2. The method as claimed in claim 1, wherein the dynamically monitoring step further comprises:

saving the measured results of the temperature and humidity of the storages by the control unit; and

calculating and obtaining an average value of the temperature and humidity of the storages and determining if the average value of the temperature and humidity of the storages is within a predetermined threshold range.

3. The method as claimed in claim 1, wherein the dynamically monitoring step further comprises:

saving the measured results of the temperature and humidity of the storages by the control unit.

4. A system for monitoring temperature and humidity of warehouses, the warehouses comprising a plurality of storages, comprising:

a cartridge installed with a detecting module;

wherein the detecting module transmits the measured results to a control unit by a wireless network; and

the control unit adjusts the temperature and the humidity of the current storage to be within a predetermined threshold range upon determining the temperature and the humidity of the current storage is not within a predetermined threshold range, and the control unit transports the cartridge from the current storage to another storage to be measured upon determining the temperature and the humidity of the current storage is within the predetermined threshold range.

5. The system as claimed in claim 4, wherein the detecting module is installed on a bottom surface of the cartridge, and the detecting module comprises a temperature-humidity sensor, an analog to digital converter (ADC), a wireless local area network (WLAN) serial service device, and a power supply that are electrically connected;

wherein the power supply supplies power to the temperature-humidity sensor, the ADC, and the WLAN serial service device;
