Detailed Description

In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

At present, the intelligent monitoring equipment for the container has the problem of single function, mainly because the container has no power supply equipment, the storage battery is required to be added to provide energy, if the function of the monitoring equipment is increased, the power consumption of the corresponding storage battery is increased, the standby time of the storage battery is shortened, and therefore, the intelligent function of the intelligent monitoring equipment used on the market is less.

The related technology energy saving method for realizing the intelligent equipment is that the main control chip is connected with the input module, the output module, the serial port module, the multi-channel sensor module, the display touch screen interface, the communication module, the positioning module and other modules, and the energy saving is realized by controlling the power failure. The disadvantage of this technique is that energy saving is achieved by controlling the power connection, and for devices requiring the whole system to not allow power down or standby throughout the day, energy saving cannot be achieved.

In another related technology for realizing the energy saving method of the intelligent terminal, an instruction is sent out in a gesture touch screen mode, and a background light source is turned off through a power management module, so that the purpose of energy saving is realized. For example, the gesture touch screen module obtains a first total duration of the gesture touch screen event when determining that the current screen is on, if the first total duration is smaller than a preset threshold, the power management module sends an extinction instruction to the LCD management module, the LCD management module controls the LCD to extinguish, and the LCD management module returns an execution result to the gesture touch screen module through the power management module. If the gesture touch screen module determines that the current screen is extinguished, acquiring a second total duration of the gesture touch screen event, and if the second total duration is smaller than a preset threshold value, sending a lighting instruction to the LCD management module through the power management module, controlling the LCD to be lighted through the LCD management module, and returning an execution result to the gesture touch screen module through the power management module by the LCD management module. However, this technology has a disadvantage in that a user needs to manually touch the screen to issue an instruction to control the backlight source, and the energy-saving function cannot be realized under the unmanned condition.

Aiming at the problems that manual control is needed in the control process of the intelligent equipment and standby cannot be continued in the related art, the embodiment of the application provides a corresponding solution, and the detailed description is given below.

The system according to claim 2, wherein in case the door status information of the container is a door open status, the first sensor acquires first weight information of the container, the second sensor acquires door status information of the container as the door open status, and the third sensor acquires first position information of the container; and under the condition that the door state information of the container is in a door closing state, the first sensor acquires second weight information of the container, the second sensor acquires the door state information of the container as the door closing state, and the third sensor acquires second position information of the container.

5. The system of claim 1, wherein the warehouse monitoring device is further configured to obtain weight information for the container, and record the weight information, the container location information, and the door status information if the weight information does not change for a second predetermined period of time.

6. The system of claim 1, wherein the data transfer between the warehouse monitoring device and the host is via bluetooth.

7. The system of claim 1, wherein the battery pack comprises a solar cell and a battery, the solar cell being configured to charge the battery.

8. The system according to claim 7, wherein the host and the collecting device are connected through an RS485 bus, a switch is arranged between a first battery pack corresponding to the host and a second battery pack corresponding to the collecting device, and the switch is used for conducting the solar cells in the first battery pack and the storage cells in the second battery pack when the electric quantity of the storage cells in the first battery pack is larger than a preset electric quantity, and the solar cells in the first battery pack and the solar cells in the second battery pack are used for jointly charging the storage cells in the second battery pack; the switch is further used for conducting the solar cells in the second battery pack and the storage cells in the first battery pack under the condition that the electric quantity of the storage cells in the second battery pack is larger than the preset electric quantity, and the solar cells in the second battery pack and the solar cells in the first battery pack are used for jointly charging the storage cells in the first battery pack.

9. The system of claim 1, wherein the host comprises a near field communication NFC module configured to receive a scanning operation of a scanning device, wake up the warehouse monitoring device according to the scanning operation, and receive weight information, the location information, and the door status information of the container returned by the warehouse monitoring device.

10. The system of claim 1, wherein the host is further configured to obtain a cargo type inside the container; determining a judging rule corresponding to the cargo type, wherein the judging rule is used for indicating environmental data indexes corresponding to different weight value intervals; determining a weight value interval corresponding to the weight of goods in the container; determining a preset environmental index corresponding to the weight of the goods according to the judging rule; comparing the environmental data index with a preset environmental index; whether alarm information is generated is determined according to the comparison result, or whether the environment information is valid is determined according to the comparison result.
