Technical Field

The present application relates to the field of communications, and in particular, to an alarm method and apparatus.

Background

With the continuous development of mobile communication, the intelligent management of assets is also widely applied.

In asset intelligent management technology, electronic devices are typically deployed on fixed assets. The electronic device is configured with a bluetooth module and a Radio Frequency Identification (RFID) module. The electronic equipment can perform RFID communication with a remote server through an RFID module in an RFID state so as to realize the services of positioning, alarming and the like of fixed assets. The electronic equipment can also carry out Bluetooth communication with other Bluetooth equipment through the Bluetooth module in a Bluetooth state so as to carry out services such as system upgrading of the electronic equipment.

However, since both the bluetooth communication and the RFID communication of the electronic device use 2.4GHz bands, the electronic device can only perform one type of communication at a time, which makes it impossible to send an RFID alarm message to a remote server for alarm when the electronic device is in a bluetooth state and detects that a fixed asset to which the electronic device belongs is moved.

For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

In the asset intelligent management technology, an electronic device is usually configured on a fixed asset, and the electronic device is used for positioning the fixed asset and automatically alarming when the fixed asset is moved.

Hereinafter, the electronic device will be referred to as a tag for description, and will not be described in detail.

Referring to fig. 1, fig. 1 is a schematic networking diagram illustrating an alarm method according to an exemplary embodiment of the present application.

In the networking shown in fig. 1, the networking mainly includes a tag configured on a fixed asset, an RFID reader, an intermediate forwarding device, a remote server, and a bluetooth device, and of course, the networking may also include other devices according to actual needs, and the networking is not specifically limited here.

The tag has a plurality of states, such as a bluetooth state, an RFID state, and the like. The tag can operate differently under different conditions. The tag can also switch between different states.

1) When the tag is in the RFID state, the tag can communicate with the RIFD of the remote server through the RFID module of the device so as to realize the positioning, alarming and other services of the fixed asset.

Specifically, the tag may send an RFID message through an RFID module of the device, and the RFID reader may identify the message and send the message to the remote server through the intermediate forwarding device. The intermediate forwarding device may include an AP (Access Point) device, a switch, an AC (Access controller) device, and the like shown in fig. 1, which are only exemplarily illustrated herein.

The communication with the remote server is realized by adopting the RFID communication mechanism, and the advantages are that: because one RFID reader can simultaneously identify the RFID messages sent by a plurality of tags, under the management scene of a large number of fixed assets, the RFID messages sent by the tags respectively configured on each fixed asset can be forwarded to the remote server by configuring one RFID reader or a small number of RFID readers.

If the communication with the remote server is realized by adopting a Bluetooth communication mechanism, a Bluetooth device needs to be arranged for the tag configured on each fixed asset, and the message sent by the tag is forwarded to the remote server through the Bluetooth device, so that a large number of Bluetooth devices need to be configured in networking, and the networking cost is greatly increased.

Therefore, the communication with the remote server is realized by adopting an RFID communication mechanism, and the communication with the remote server can be realized by only configuring one or a small number of RFID readers, so that the networking configuration cost can be greatly reduced.

2) When the tag is in a Bluetooth state, the tag can realize Bluetooth communication with a near-distance Bluetooth device through the Bluetooth module so as to upgrade a tag system.

However, since both bluetooth communication and RFID communication of the electronic device use a 2.4GHz band and the tag can only be in one state at a time, the tag can only perform one communication at a time, which makes it impossible to transmit an RFID alarm message to a remote server if it is detected that the fixed asset to which the tag belongs is moved when the tag is in the bluetooth state.

In view of this, the present application provides an alarm method, when a tag detects that a fixed asset to which a device belongs is moved, if it is determined that a current state of the device is a bluetooth state, the current state of the device is switched from the bluetooth state to an RFID state, and an RFID alarm message for indicating that the fixed asset is moved is sent to a remote server in the RFID state.

When the label detects that the fixed asset to which the label belongs is moved, if the current state of the label is determined to be the Bluetooth state, the label jumps out of the Bluetooth state and enters the RFID state, so that the label can send an RFID alarm message in the RFID state, and therefore the alarm that the fixed asset to which the label belongs is moved is detected by the label in the Bluetooth state.

Referring to fig. 2, fig. 2 is a flowchart illustrating an alarm method according to an exemplary embodiment of the present application. The process can be applied to a tag (i.e., an electronic device), and the method can include the following steps.

Step 201: and when the target object to which the equipment belongs is detected to be moved, determining the current state of the equipment.

Wherein the target object may be a fixed asset, such as a good in a warehouse, etc. The target object is labeled.

The tag is provided with a designated sensor for detecting whether the object moves, such as an acceleration sensor (e.g., G-sensor), a gravity sensor, and the like.

When the designated sensor detects that the target object to which the tag belongs is moved, the designated sensor may report an interrupt signal to the tag.

When the tag receives the interrupt signal, it may be determined that the target object to which the tag belongs is moved.

When detecting that the target object to which the tag belongs is moved, the tag can check the current state of the device.

When the method is implemented, since the maintenance and management of the tag state and the switching between the states can be implemented by the state machine, when the current state of the device is checked, the current state of the state machine of the device can be checked.

Of course, the current state of the device may also be determined by other state detection methods commonly used by those skilled in the art, which are only exemplary and not specifically limited herein.

Step 202: and if the equipment is in the Bluetooth state currently, switching the current state of the equipment from the Bluetooth state to a Radio Frequency Identification (RFID) state, and sending an RFID alarm message for indicating that the target object is moved to a remote server in the RFID state.

When the switching is realized, the switching of the current state of the device can be realized through a state machine.

Specifically, if the state machine of the tag is currently in the bluetooth state, the state machine is controlled to exit the bluetooth state and then enter the RFID state. In the RFID state, the tag may send an RFID alert message to a remote server indicating that the target object is moved.

It should be noted that the bluetooth status may be further subdivided into a bluetooth broadcast status and a bluetooth connected status.

When the state machine of the tag is in a bluetooth broadcast state, the tag may broadcast a request message for establishing bluetooth connection, so as to establish bluetooth connection with surrounding bluetooth devices.

When the state machine of the tag is in a bluetooth connected state, the tag can perform bluetooth communication with the connected bluetooth device.

In this embodiment of the application, when the state machine of the tag is currently in the bluetooth broadcast state or the state is currently in the bluetooth connected state, the tag needs to control the state machine to exit the bluetooth broadcast state or the bluetooth connected state, and then enter the RFID state. In the RFID state, the tag may send an RFID alert message to a remote server indicating that the target object is moved

If the state machine of the tag is currently in the RFID state, the tag may send an RFID alarm message to the remote server indicating that the target object is moved.

Of course, the switching of the current state of the device may also be determined by other state switching manners commonly used by those skilled in the art, where the implementation of the state switching by the state machine is merely exemplary and not specifically limited.

In addition, in order to prevent the frequent sending of the alarm message due to the target object being frequently moved for a short time, in the embodiment of the present application, after the alarm message is sent, if it is detected again that the target object to which the device belongs is moved within a preset time period, the tag prohibits sending the RFID alarm message to the remote server.

Specifically, after sending the RFID alarm message, the tag may start a timer, prohibit sending the RFID alarm message to the remote server if the interrupt signal reported by the specified sensor is received again before the timer expires, and close the timer after the timer expires.

The timeout duration of the timer may be set by a developer according to actual conditions, and the timeout duration of the timer may be set to 2 seconds in general, which is only exemplary and not specifically limited herein.

Compared with the method that the RFID warning message is sent only when the target object is detected to be moved, the method has the advantages that only one RFID warning message is sent when the target object is frequently moved in a short time, so that the sending amount of the RFID warning message is greatly reduced, on one hand, the link bandwidth occupied by a large number of RFID warning messages can be reduced, and on the other hand, the working pressure of the remote server for processing the RFID warning message can be greatly reduced.

In the embodiment of the application, besides the tag can be switched from the bluetooth state to the RFID state, the tag can also be switched from the RFID state to the bluetooth state.

Specifically, the tag is configured with an NFC (Near Field Communication) module. The asset manager carries a handheld terminal configured with an NFC module or holds an NFC medium (e.g., an NFC card). When an asset manager's handheld terminal or NFC card is in proximity to the tag, the NFC module of the tag may detect the NFC signal.

After the tag detects the NFC signal, the tag can switch the current state of the device from the RFID state to the bluetooth broadcast state.

Specifically, the tag can switch the state machine of the device from the RFID state to the Bluetooth broadcast state.

Of course, switching the current state of the device from the RFID state to the bluetooth broadcast state may also be implemented by other state switching manners commonly used by those skilled in the art, where the implementation of state switching by a state machine is merely exemplary and is not specifically limited.

As can be seen from the above description, on the one hand, when the tag detects that the target object to which the tag belongs is moved, if it is determined that the current state of the device is the bluetooth state, the tag jumps out of the bluetooth state and enters the RFID state, so that the tag can send an RFID alarm packet in the RFID state, and therefore, the tag detects that the target object to which the tag belongs is moved in the bluetooth state.

On the other hand, after the alarm message is sent, if the device is detected to be moved again within the preset time length, the RFID alarm message is not sent to the remote server, so that the frequent sending of the alarm message due to the fact that the target object is frequently moved in a short time is prevented.

The following describes an alarm method provided by the present application with reference to fig. 3 by taking an example of switching the tag state by a state machine.

Referring to fig. 3, fig. 3 is a schematic diagram of a state machine of an electronic device according to an exemplary embodiment of the present application.

In fig. 3, the state machine of the tag (i.e., the electronic device) includes at least 4 states, which are an initialization state, a bluetooth broadcast state, a bluetooth connected state, and an RFID state, respectively. Of course, the state machine of the tag may also include other states according to the needs of the actual application, and the state of the state machine of the tag is not specifically limited herein.

An initialization state: when the state machine of the tag is in this initialization state, the tag may complete the initialization setup.

Bluetooth broadcast state: when the state machine of the label is in a Bluetooth broadcast state, the label can broadcast a request message for establishing Bluetooth connection so as to establish connection with surrounding Bluetooth equipment.

Bluetooth connected state: when the state machine of the tag is in a bluetooth connected state, the tag can perform bluetooth communication with a bluetooth device that establishes a bluetooth connection.

RFID state: the tag may communicate RFID with the remote server when the state machine of the tag is in the RFID state.

It should be noted that the bluetooth broadcast state and the bluetooth connected state may be collectively referred to as the bluetooth state described above.

In the embodiment of the present application, the state machine of the tag can be switched in the above four states.

1) When the tag is started, the state machine of the tag can perform an initialization state in which the tag can perform initialization setting. After the initialization setting is completed, the state machine of the tag can be switched from the initialization state to the Bluetooth broadcast state.

2) In the bluetooth broadcast state, the tag may broadcast a request message to establish a bluetooth connection. After the request message for establishing the Bluetooth connection is broadcasted, a Bluetooth broadcast timer can be started. If a response message aiming at the request message for establishing the Bluetooth is received before the Bluetooth broadcast timer is overtime, the Bluetooth connection is established with a sender of the response message, the state machine is switched from the Bluetooth broadcast state to a Bluetooth connected state, and the Bluetooth communication is carried out with the Bluetooth equipment for establishing the connection in the Bluetooth connected state.

And if the response message aiming at the Bluetooth establishment request message is not received before the Bluetooth broadcast timer is overtime, switching the state machine from the Bluetooth broadcast state to an RFID state, and carrying out RFID communication with a remote server in the RFID state.

In addition, an interrupt signal may be reported when the tag's G-sensor (an acceleration sensor) detects that the target object to which the tag belongs is moved. When the state machine of the tag is in a Bluetooth broadcast state and receives an interrupt signal reported by the G-sensor, the tag can switch the state machine from the Bluetooth broadcast state to an RFID state, and send an RFID alarm message for indicating that the target object is moved to a remote server in the RFID state. And if the interrupt signal reported by the G-sensor is received again within the preset time after the RFID warning message is sent, the RFID warning message is not sent to the remote server.

3) Under the Bluetooth connected state, if the Bluetooth connection disconnection between the state machine and the Bluetooth equipment of the opposite terminal is detected, the state machine of the tag can be switched from the Bluetooth connected state to the Bluetooth broadcast state.

In addition, in the bluetooth connected state, if an interrupt signal reported by the G-sensor is received, the tag may switch the state machine from the bluetooth connected state to the RFID state, and in the RFID state, send an RFID alarm message indicating that the target object is moved to the remote server. And if the interrupt signal reported by the G-sensor is received again within the preset time after the RFID warning message is sent, the RFID warning message is not sent to the remote server.

4) In the RFID state, if the label detects an NFC signal generated by an asset manager through brushing an NFC medium, the state machine of the label is switched from the RFID state to the Bluetooth broadcast state.

Referring to fig. 4, fig. 4 is a hardware structure diagram of an electronic device according to an exemplary embodiment of the present application.

As shown in fig. 4, the electronic device may include a first network chip 401, a power supply 402, and a G-Sensor 403.

The bluetooth module and the RFID module of the first network chip 401 may communicate through an antenna having a communication frequency band of 2.4GHz, and the NFC module may communicate through an NFC antenna.
