technical field

The invention relates to the field of anti-theft and monitoring of valuables, in particular to a monitoring system for valuables based on NB-IOT technology.

Background technique

At present, the existing alarm systems in the field of valuables anti-theft and monitoring are roughly divided into the following two types:

One is a wireless anti-theft alarm system, which is placed under valuables or used to hang valuables, including sensors, Bluetooth modules and microprocessors; sensors include photosensitive sensors, pressure sensors, micro switches, ball switches and acceleration One or more of the sensors, the sensor senses the changes of the surrounding environment of the valuables and the items, and transmits the change information to the microprocessor, and the microprocessor receives the information transmitted by the sensors, and sends an alarm message through the Bluetooth module. The disadvantage of the alarm system is that the sensors are redundant, and the system includes sending equipment and receiving equipment, which makes the circuit structure more complicated. If the network is disconnected, the alarm function of the equipment will be invalid.

One is an alarm system that uses a buzzer. The disadvantage of this system is that: the alarm mode is single, and the buzzer is used for alarm. If the valuables are left unattended, the alarm will still fail; The use of a reed switch connected to a spring results in an inaccurate trigger signal, and the slight movement of valuables cannot trigger an alarm, and frequent shaking can also cause a false alarm of the device.

Therefore, those skilled in the art are committed to developing a valuables monitoring system based on NB-IOT technology, which uses fewer sensors and a simple circuit structure to achieve accurate alarms in various alarm modes, and at the same time realizes when the network is disconnected. The alarm function can still be realized.

Description of drawings

Fig. 1 is a schematic diagram of system modules of a preferred embodiment of the present invention.

Detailed ways

The following describes several preferred embodiments of the present invention with reference to the accompanying drawings, so as to make the technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned herein.

In the drawings, components with the same structure are denoted by the same numerals, and components with similar structures or functions are denoted by similar numerals. The size and thickness of each component shown in the drawings are shown arbitrarily, and the present invention does not limit the size and thickness of each component. In order to make the illustration clearer, the thickness of parts is appropriately exaggerated in some places in the drawings.

As shown in Figure 1, the technical solution is realized through the following steps:

Step 1: Paste the small magnet of the present invention on the outside of the valuables. The sticking place is located at the contact position between the valuables and the protective frame, and this position cannot be easily touched or damaged by a third party. Make the magnet and the reed switch sensor as close as possible to achieve the effect that when the magnet leaves with the object, the state of the reed switch changes, and when the magnet is put back with the object, the state of the reed switch returns to its original state.

Step 2: The sensor module connected to the NB-IOT device, including the reed switch sensor, temperature and humidity sensor, and six-axis acceleration sensor. Among them, the reed switch sensor is connected to the common input and output port of the NB-IOT device, and the other side is fixed to the vicinity of the magnet when the valuables are placed on the protective shelf. The temperature and humidity sensor and the six-axis acceleration sensor are connected to the NB-IOT device.

Step 3: The NB-IOT device connected to the sensor module through a cable and connected to the OceanConnect platform through the narrowband IoT northbound port is used for calculation and logic processing of the signal from the sensor. By configuring the module software to configure the inserted IoT card information and modify the target address to be sent by the module, the logical value of whether the item that will be attached to the magnet at the NB-IOT device side exists, the logical value of whether the entire system is moved, and The temperature and humidity values are sent to the OceanConnect platform through NB-IoT.

Step 4: Add an item detection system to the OceanConnect platform, and develop device files to describe the device type and device service capabilities. On the OceanConnect platform interface, the message mapping between the device and the platform is completed graphically, and the device is registered through the developer. In this way, the NB-IOT device that has installed the IoT card and set the IP address and other information can report data to the OceanConnect platform.

Step 5: The cloud server is a northbound application relative to the OceanConnect platform. In addition to obtaining the current data and historical data of the device through the data query interface, the northbound application can also obtain real-time data through message subscription. When the data reported by the southbound device reaches the platform, the platform will check whether there is a subscription. The cloud server pushes the obtained message to the device owner's mobile phone APP or sends a short message reminder to it.

Step 6: Connect the mobile phone and the cloud server through the Internet or the 2/3/4G signal of the mobile phone. The logical value of whether the item attached to the magnet exists, the logical value of whether the entire system is moved, and the temperature and humidity can be sent via SMS. The value is passed to the mobile phone, or directly to the mobile APP.

The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and changes according to the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art shall be within the scope of protection defined by the claims.
