Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, the present invention provides a method for monitoring an NB-IoT-based important item, which includes the following steps:
s1, acquiring real-time environment information of the monitored object by the sensing detection unit;
s2, uploading real-time environment information of the monitored article by the sensing detection unit;
s3, when the environmental information of the monitored object exceeds the preset monitoring parameters, the sensing detection unit starts the NB-IoT communication module and uploads alarm information, wherein the alarm information comprises real-time position information of the monitored object;
wherein, the monitoring preset parameter is pre-stored in the sensing detection unit before step S1, the sensing detection unit has a corresponding memory and a corresponding processor, the monitoring preset parameter can be one or more value ranges, and when the value of one or more real-time environment information exceeds the monitoring preset parameter, the sensing detection unit uploads alarm information;
in step S2, the number of times and interval period of uploading the real-time environment information by the sensing unit may be preset, and for example, the time and/or hour interval may be set to be set from when the sensing unit is installed in place and debugged, and when the display or storage of the important item is finished, so that the user can obtain the time-sharing information and the information summary according to the time unit.
According to the difference between the environment where the monitored object is located and the display or storage state, the real-time environment information of the monitored object, which needs to be acquired and uploaded by the sensing detection unit, is also correspondingly different, for example, in an embodiment provided by the present invention, the monitored object is in a static display or storage state, and at this time, the real-time environment information of the monitored object includes: the temperature information, the humidity information and the position information of the environment where the monitored object is located, and the logic value information of whether the monitored object and/or the environment where the monitored object is located vibrate or displace; the information is respectively obtained by a sensor or a device with a corresponding function; it should be understood that the monitoring preset parameters also have pre-stored acceleration reference information for determining whether the monitored object and/or the environment where the monitored object is located vibrate or displace; for example, in some scenarios, the monitored object is a piece of jewelry for exhibition, during which the sensor acquires corresponding logic value information due to slight collision or vibration of the display platform, the sensing detection unit compares the logic value information with the acceleration reference information, and if the logic value information does not exceed the range of the acceleration reference information, the sensing detection unit does not perform step S3, but, in consideration of overall protection of the monitored object, the sensing detection unit still uploads the logic value information so that the user can perform overall analysis; in addition, in the static monitoring, the sensing detection unit is in a state of a power-saving mode;
in order to reduce the power consumption of the sensing detection unit, in some improved modes, the sensing detection unit uploads the real-time position information of the monitored object through prestored satellite ephemeris data, for example, ephemeris data which is several kilometers of a square of an important object or covers an administrative area can be stored, so that when a GPS signal is weak, corresponding position information can be uploaded regularly according to the ephemeris data, and a data clue is provided for a user to alarm;
in another embodiment, the monitored object is in a state in the way of transportation, which is dynamic monitoring, and the sensing detection unit is set to ignore the logic value information of whether the monitored object and/or the environment where the monitored object is located vibrate or displace; the real-time environmental information of the monitored object comprises: temperature information, humidity information and position information of the environment where the monitored object is located; different from the static monitoring, the temperature information, humidity information, and location information uploaded by the sensing detection unit during the dynamic monitoring are used for data processing and drawing graphic display information, for example, a plurality of location information are drawn into a route map displayed by a user terminal, and this function is completed by an external device and is described in the following description;
in addition, when the real-time environment information in the dynamic monitoring exceeds the monitoring preset parameters, the sensing detection unit uploads alarm information, for example, when the real-time position deviates from the position point of the preset moving route of the important object, the sensing detection unit can judge that an abnormal condition occurs and upload the alarm information; it should be understood that the monitoring preset parameters include a preset moving route of the monitored object, and in practical use, a user can plan one or more important object moving paths, and when the paths are multiple, the paths can be understood to have ideal paths and standby paths, so as to prevent the false alarm state of the sensing detection unit occurring in the journey from being temporarily changed when an emergency situation occurs in the transportation process.
In the embodiment provided by the invention, the method for monitoring the self state of the sensing detection unit also comprises the following steps:
s4, the sensing detection unit acquires the information of the electric quantity of the sensing detection unit and/or the information of the integrity of the real-time environment information of the monitored object, and compares the information with the monitoring preset parameters;
s5, when the information of the self-electricity quantity information of the sensing detection unit and/or the integrity of the real-time environment information of the monitored object exceeds the preset monitoring parameter, the sensing detection unit uploads alarm information through the NB-IoT communication module;
the integrity of the real-time environmental information of the monitored object can be understood as whether one or more pieces of real-time environmental information forming the real-time environmental information of the monitored object are uploaded according to a preset period or not, when part of the real-time environmental information is missing, the sensor providing the relevant information can be considered to be failed, and when all the real-time environmental information is missing, the sensing detection unit can be considered to be shielded or damaged;
the power monitoring can be to set an alarm value in a monitoring preset parameter as required, for example, the sensing detection unit uploads alarm information through the NB-IoT communication module when the power is reduced to 20%, or can be to upload the alarm information immediately when the sensing detection unit monitors that the sensor is powered off.
In the embodiment of the present invention, the method further includes a process of preparing the sensing detection unit for power on, and specifically, the monitoring method further includes the following steps before step S1:
s0.1, starting a sensing detection unit;
s0.2, receiving an Internet of things signal by a sensing detection unit;
s0.3, logging in a cloud platform by a sensing detection unit, and sending identity information of the cloud platform to the cloud platform;
in the embodiment provided by the invention, the sensing detection unit also supports real-time updating of the monitoring preset parameter, the updating mode takes the last change date in the file log as a reference, and the method comprises the following steps after the step S0.3:
s0.4, the sensing detection unit acquires the change time information of the monitoring preset parameter in the user terminal, and when the change time of the monitoring preset parameter in the user terminal is later than the change time of the monitoring preset parameter stored in the user terminal, the sensing detection unit acquires and stores the monitoring preset parameter in the user terminal.
In the embodiment provided by the present invention, when the sensing unit is used for the first time, the step of performing before step S1 is:
the sensing detection unit A acquires and stores monitoring preset parameters.
In the embodiment provided by the present invention, the sensing unit further maintains or cancels the interaction process of monitoring the important item according to the user instruction, and specifically, the monitoring method further includes the following steps before step S1:
