And the design of NB-IoT chip has reduced the consumption greatly compared with gateway equipment, has also avoided gateway equipment simultaneously because the software and hardware all has 2 trouble entrances of MCU and communication module and the problem of easily makeing mistakes.

The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings

Fig. 3 is a schematic structural diagram of an intrusion monitoring device according to an embodiment of the present invention. As shown in fig. 3, the intrusion monitoring device provided in this embodiment includes: the system comprises a main control terminal 10 and N node terminals 20, wherein N is greater than or equal to 1.

Wherein, the main control terminal 10 includes: the NB-IoT chip 101 is connected to the first communication module 102, and the master control terminal 10 is connected to the N node terminals 20 through the first communication module 102. The NB-IoT101 chip is configured to report corresponding alarm information to the server through the NB-IoT base station when the main control terminal 10 or the node terminal 20 detects that someone invades.

Specifically, when the NB-IoT chip 101 of the main control terminal 10 determines that someone invades, the NB-IoT chip 101 generates alarm information, that is, first alarm information, and sends the alarm information to the server through the NB-IoT base station in fig. 2, and the server further sends the alarm information to the user terminal. When the node terminal 20 detects that someone invades, the node terminal 20 generates alarm information, that is, second alarm information, and further sends the alarm information to the NB-IoT chip 101 of the main control terminal 10, the NB-IoT chip 101 sends the alarm information to the server through the NB-IoT base station in fig. 2, and the server further sends the alarm information to the user terminal.

No matter the master control terminal 10 or the node terminal 20 detects that someone invades, the process of sending alarm information to the user terminal does not involve gateway equipment, so the invasion monitoring device provided by the embodiment does not need to deploy gateway equipment on a monitoring field. Compared with the gateway equipment, the design of the NB-IoT chip 101 greatly reduces the power consumption, and simultaneously avoids the problem that the gateway equipment is easy to make mistakes due to the fact that software and hardware have 2 fault inlets of the MCU and the communication module.

In one possible implementation, referring to fig. 3, the node terminal 20 may include: the processor 201 is connected with the second communication module 202, and the master control terminal 10 realizes communication with the node terminal 20 through the connection of the first communication module 102 and the second communication module 202. The node terminal 20 determines whether a person invades the node terminal by the processor 201, and if so, the processor 201 generates corresponding alarm information.

In a possible implementation manner, the main control terminal 10 may further include a first intrusion detection sensor 103, where the first intrusion detection sensor 103 is connected to the NB-IoT chip 101, and the NB-IoT chip 101 may determine whether there is an intrusion in the position where the main control terminal 10 is located according to infrared interruption information detected and sent by the first intrusion detection sensor 103, and if so, generate first alarm information; accordingly, the node terminal 20 may further include: and the second intrusion detection sensor 203 is connected with the processor 201 of the node terminal 20, and the processor 201 can judge whether the node terminal 20 is in the position where the node terminal is located according to infrared interruption information detected and sent by the second intrusion detection sensor 203, and if so, generate second alarm information and send the second alarm information to the NB-IoT chip 101 through the second communication module.

Optionally, both the first intrusion detection sensor 103 deployed in the master control terminal 10 and the second intrusion detection sensor 203 deployed in the node terminal 20 may be infrared sensors.

The following describes a process of generating first alarm information by the NB-IoT chip 101 in the main control terminal 10:

step a1, after the NB-IoT chip 101 receives the first report of the infrared interruption information from the first intrusion detection sensor 103, the value of the counter is updated to the first preset value, and the time accumulation value is set to the second preset value, and the time accumulation value is accumulated over time.

Optionally, the first preset value may be 1, and the second preset value may be 0.

And step B1, after the NB-IoT chip 101 receives the infrared interruption information reported for multiple times after the first intrusion detection sensor 103 reports for the first time, judging whether intrusion exists according to the time reported for multiple times, the first preset value and the second preset value, and if yes, generating first alarm information according to the time reported for multiple times, the first preset value and the second preset value.

Specifically, for each report in the multiple reports according to the time sequence, if the time accumulation value is within a preset time range, the NB-IoT chip adds 1 to the value of the counter, and sets the time accumulation value to a second preset value again; and when the value of the counter is equal to a third preset value, the NB-IoT chip sets the time accumulation value to a second preset value again, stores the infrared interruption information reported each time after the value of the counter is greater than the third preset value, and when the value of the time accumulation value is greater than or equal to a fourth preset value, the NB-IoT chip generates the first alarm information according to the stored infrared interruption information.

The process of step A1-step B1 described above is described below with reference to FIG. 4:

and S401, initializing after the NB-IoT chip 101 reports the alarm information to the server last Time, clearing the value of the Counter, clearing the Time accumulation value Time, and automatically accumulating the Time accumulation value Time along with the Time.

S402, after the NB-IoT chip 101 receives the first report of the infrared interruption information from the first intrusion detection sensor 103, it updates the Counter value to 1, and sets the Time accumulation value Time to zero.

S403, when the NB-IoT chip 101 receives the infrared interruption information reported by the first intrusion detection sensor 103 again, determining whether the value of the Time accumulation value Time is smaller than the preset threshold X, for example, 2min, if so, not processing the infrared interruption information reported this Time, that is, the NB-IoT chip 101 does not process the infrared interruption information received within 2min after receiving the infrared interruption information last Time, and if the value of the Time accumulation value Time has been accumulated to the preset Time range X +2 ≧ Time ≧ X (for example, [2min,4min ]), adding 1 to the value of the counter, and setting the Time accumulation value Time to zero again.

S404, when the outside line interruption information is received next, the same processing as S403 is performed, and the Time accumulation Time is set to zero again until the value of the Counter equals to a third preset value Y (for example, 3).

S405, storing the infrared interruption information reported each time by the first intrusion detection sensor 103 after the value of the Counter is greater than the third preset value Y.

And S406, when the Time accumulation value Time is greater than or equal to a fourth preset value Z (for example, 30min), determining that someone invades, and reporting all the stored infrared interruption information serving as first alarm information to the server.

The method for generating the first alarm information in S404-S406 avoids processing excessive redundant messages and reduces power consumption.

In a possible implementation manner, when the NB-IoT chip 101 reports the first alarm information to the server or sends a heartbeat to the server, as shown in fig. 5, it may be determined whether the current arming state needs to be updated to disarming in the following manner:

s501, checking whether a disarming command is cached in the server; if yes, go to step S502.

S502, update the state of the NB-IoT chip 101 to be revoked, and broadcast a state update message to each node terminal 20 through the first communication module 102, so that each node terminal 20 updates the state to be revoked.

S503, if the error message of changing the state fed back by any node terminal 20 is received within a preset time period (for example, 5S), sending the state update message to the corresponding node terminal 20 again until the node terminal 20 does not feed back the error message of changing the state within the preset time period.

Optionally, if the NB-IoT chip 101 resends the status update message to the node terminal feeding back the status change error message more than N times, and the corresponding node terminal 20 still feeds back the status change error message within the preset time period, the NB-IoT chip 101 reports a command to the server to set an error alarm.

Accordingly, if the intrusion monitoring device is currently in the disarmed state, and the NB-IoT chip 101 sends a heartbeat to the server, it can also be determined whether the current disarmed state needs to be updated to arming in a manner similar to S501-S503:

s601, checking whether a defense deploying command is cached in the server; if yes, go to step S602.

S602, update the state of the NB-IoT chip 101 to arming, and broadcast a state update message to each node terminal 20 through the first communication module 102, so that each node terminal 20 updates the state to arming.

S603, if a status change error message fed back by any node terminal 20 is received within a preset time period (for example, 5S), sending the status update message to the corresponding node terminal 20 again until the node terminal 20 does not feed back the status change error message within the preset time period.

Optionally, the main control terminal 10 may default to send a heartbeat every C hours (the value C is default to 0.5) in a time period from point a (the value a is default to 9) to point B (the value B is default to 21) every day, and send a heartbeat every D hours (the value D is default to 2) in the rest of the time period, so that the main control terminal can receive a server command immediately in the daytime and avoid false alarm caused by the user not leaving the site, and power consumption can be reduced at night.

When a user needs to change the arming/disarming state of the intrusion monitoring device, the user can send a command to the server, the server caches the command, and the arming/disarming states of the main control terminal and the node terminal are changed by checking the command when the main control terminal 10 reports heartbeat or alarm information. It should be noted that: the main control terminal 10 may also support the user to set a fixed defense period every day, in which case, the server controls the intrusion monitoring device to be in an on state in the defense period, and controls the intrusion monitoring device to be in an off state in a period other than the defense period.

For the process of generating the second alarm information by processor 201 in node terminal 20, the process may include:

in step a2, after receiving the first report of the infrared interruption information from the second intrusion detection sensor 203, the processor 201 sets the value of the counter to a first preset value, and sets the time accumulation value to a second preset value, where the time accumulation value is accumulated over time.

Optionally, the first preset value is 1, and the second preset value is 0.

Step B2, after the processor 201 receives the infrared interruption information reported many times after the first report by the second intrusion detection sensor 203, it determines whether there is an intrusion according to the time of the multiple reports, the first preset value, and the second preset value, and if so, generates the second alarm information according to the time of the multiple reports, the first preset value, and the second preset value.

Specifically, for each report in the multiple reports according to the time sequence, if the time accumulation value is within a preset time range, adding 1 to the value of the counter, and setting the time accumulation value as a second preset value again; and when the value of the counter is equal to a third preset value, setting the time accumulation value as a second preset value again, storing infrared interruption information reported each time after the value of the counter is greater than the third preset value, and when the time accumulation value is greater than or equal to a fourth preset value, generating second alarm information according to the stored infrared interruption information.

Further, the processor 201 sends the second alarm information to the NB-IoT chip 101 through the second communication module 202, and the NB-IoT chip 101 reports to a server through the NB-IoT base station.

Specifically, the process of generating the second alarm information by the processor 201 according to the infrared interruption information reported by the second intrusion detection sensor 203 may refer to the process of generating the first alarm information by the NB-IoT chip 101 according to the infrared interruption information reported by the first intrusion detection sensor 103 in fig. 4, which is not described herein again.

In a possible implementation manner, the main control terminal 10 may further include a first buzzer 104, and each node terminal 20 may further include a second buzzer 204. The first buzzer 104 of the main control terminal 10 is connected to the NB-IoT chip 101, and when the NB-IoT chip 101 determines that someone invades, the NB-IoT chip sends a control instruction to the first buzzer 104, so that the first buzzer 104 gives an alarm. The second buzzer 204 is connected to the processor 201 of the node terminal 20, and when the processor 201 determines that the person invades, the processor 201 sends a control instruction to the second buzzer 204 to enable the second buzzer 204 to give an alarm.

Optionally, the first communication module 102 and the second communication module 202 are both energy harvesting EnOcean modules. Because the EnOcean module has an energy collection function, the EnOcean module can be used for supplying power to the main control terminal 10 and each node terminal 20, so that the intrusion monitoring device can realize self-power supply.
