Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a community security system based on the Internet of Things. Background Art

[0002] Security work is related to everyone's life and property, and plays an important role in community property work. In existing community security systems, such as the smart community security system based on the Internet of Things disclosed in Chinese Patent Publication No. CN111429327A, it includes a data acquisition module, a data analysis module, a controller, a signal matching module, an information collection module, an information processing module and a data output module; the data acquisition module is used to collect the identification security information of each building in the community and transmit it to the data analysis module; after receiving the identification security information of each building in the community, the data analysis module performs an inner-layer security supervision analysis operation on it, obtains the inner-layer building security supervision abnormal signal or the inner-layer building security supervision normal signal corresponding to the community, and transmits it to the signal matching module via the controller; this security system can only make a comprehensive assessment of the security status of each link in the community, but cannot immediately improve the safety of the community security.

[0003] To this end, the present invention provides a community security system based on the Internet of Things, which has a simple structure, is easy to use, and effectively improves the confidentiality and safety of community security work. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a community security system based on the Internet of Things, which can be used for property management in existing communities. The manager sends patrol tasks to the smart mobile terminal carried by the security guard through the management terminal, and then uses the access control unit to verify the completion of the security guard's patrol task, and decides whether to contact the access control for the security guard who undertakes the patrol task based on the verification result. At the same time, the travel verification process is placed in the smart mobile terminal for verification, and the executor's travel trajectory is not sent to the access control control unit. On the basis of ensuring the confidentiality of the executor's travel trajectory, it is guaranteed that all patrol trajectory information will not be leaked at the same time, thereby improving the confidentiality and safety of community security work.

[0005] A community security system based on the Internet of Things, including a management terminal, an access control unit and a smart mobile terminal.

[0006] The management terminal is used to input the target area location information and identity list information into the access control unit;

[0007] The access control unit includes a first control module, an identity information verification module, a location information sending module and a door lock control module. The identity information verification module, the location information sending module and the door lock control module are respectively connected to the first control module. The identity information verification module is used to verify the received identity information with the identity list information. The location information sending module is used to send the target area location information to the smart mobile terminal after the identity information is verified. The door lock control module is used to control the opening and closing state of the access control;

[0008] The smart mobile terminal includes a second control module, an identity information sending module, a positioning module and a location information verification module. The identity information sending module, the positioning module and the location information verification module are respectively connected to the second control module. The positioning module is used to record the travel trajectory of the smart mobile terminal. The identity information sending module is used to send identity information to the access control control unit. The location information verification module is used to compare and verify the received target area location information with the recorded travel trajectory after sending the identity information, and feed back the verification result to the access control control unit.

[0009] Furthermore, the smart mobile terminal records the travel trajectory through the positioning module. During the access control process, the smart mobile terminal sends identity information to the access control control unit through the identity information sending module. The access control control unit receives the identity information through the identity information receiving module, and verifies the received identity information with the identity list information through the identity information verification module. After the verification is passed, the access control control unit sends the target area location information to the smart mobile terminal through the location information sending module. After the smart mobile terminal receives the target area location information, it compares and verifies the travel trajectory with the target area location information through the location information verification module, and feeds back the verification result to the access control control unit. The access control control unit controls the opening and closing state of the access control according to the travel trajectory verification result.

[0010] Furthermore, identity information is preset in the smart mobile terminal.

[0011] Furthermore, the identity information in the smart mobile terminal is unique. In actual applications, one smart mobile terminal corresponds to one identity information, and the identity information is unique, and the identity information in different smart mobile terminals is different.

[0012] Furthermore, the management terminal is also used to send travel instruction information to the smart mobile terminal, and the travel instruction information includes the target area location information. In actual application, when it is necessary to assign someone to a certain area for investigation, the management terminal can send travel instruction information to the smart mobile terminal. The travel instruction information includes the location information of the area, that is, the target area location information. The executor can go to the target area to complete the task after receiving the travel instruction information through the smart mobile terminal. At the same time, the management terminal is used to input the target area location information and identity list information into the access control unit; when the executor returns after completing the task, the access control control unit verifies the completion of the executor's travel instruction information. Specifically, the access control control unit first verifies the executor's identity information. The executor sends the identity information to the access control control unit through the identity information sending module in the smart mobile terminal. The access control control unit receives the identity information through the identity information receiving module and receives the received identity information. The identity information of the executor is verified by the identity information verification module and the identity list information. After the verification is passed, the access control control unit sends the target area location information corresponding to the identity information to the smart mobile terminal through the location information sending module. After the smart mobile terminal receives the target area location information, it compares and verifies the travel trajectory with the target area location information through the location information verification module, and verifies whether the executor has reached the target area location within the smart mobile terminal without sending the executor's travel trajectory outward, thereby ensuring the confidentiality of the executor's travel trajectory. The executor then feeds back the verification result to the access control unit through the smart mobile terminal. The access control control unit determines whether the executor has reached the target area and completed the travel instruction information based on the travel trajectory verification result, and then decides whether to release the access control for the executor based on the verification result.

[0013] Furthermore, the management terminal inputs the target area location information into the access control unit, tagged with the corresponding identity information preset in the smart mobile terminal. In actual application, the management terminal can simultaneously send different travel instruction information to multiple smart mobile terminals. After sending the travel instruction information to the smart mobile terminal, the management terminal inputs the travel instruction information tagged with the identity information into the access control unit. That is, after the management terminal delegates the travel task, the management terminal sends the travel task and the corresponding executor's identity information to the access control unit. The access control unit then performs subsequent access control based on the received travel instruction information (including the target area location information) and the identity list information.

[0014] Furthermore, the access control unit includes a first communication module connected to the first control module, and the access control unit is respectively connected to the management terminal and the smart mobile terminal through the communication module.

[0015] Furthermore, the smart mobile terminal includes a second communication module connected to the second control module, and the smart mobile terminal is communicatively connected to the first communication module through the second communication module.

[0016] Furthermore, the access control unit includes a first power supply connected to the first control module.

[0017] Furthermore, the smart mobile terminal includes a second power supply, and the second power supply is connected to the second communication module.

[0018] Furthermore, when the verification result fed back to the access control control unit is that the travel trajectory involves the location information of the target area, the access control control unit controls the release of access control.

[0019] Furthermore, when the verification result fed back to the access control unit is that the travel trajectory involves the target area location information, the verification result is passed; when the travel trajectory does not involve the target area location information, the verification result is failed.

[0020] Furthermore, when the verification result fed back to the access control control unit is that the travel trajectory does not involve the target area location information, the verification result is failed, and the access control control unit maintains the access control enabled state.

[0021] Furthermore, when the identity information verification module verifies the received identity information and the identity list information, and the verification result is that the identity list information does not contain the identity information, the verification result fails, and the access control unit does not send the target area location information to the smart mobile terminal, and keeps the access control in the enabled state.

[0022] Furthermore, the identity information verification module verifies the received identity information and the identity list information. When the verification result is that the identity list information contains the identity information, the verification result is passed, and the access control unit can send the target area location information to the smart mobile terminal.

[0023] Furthermore, the access control unit includes a prompt module, and the prompt module is used to display verification information.

[0024] Furthermore, the identity information verification module verifies the received identity information and the identity list information. If the verification result is that the identity list information does not contain the identity information, the verification result fails, and the prompt module displays verification information indicating that the identity information does not match.

[0025] Furthermore, the identity information verification module verifies the received identity information and the identity list information. When the verification result shows that the identity list information contains the identity information, the verification result passes, and the prompt module displays verification information that the identity information matches.

[0026] Furthermore, the access control control unit receives identity information through the identity information receiving module, and verifies the received identity information with the identity list information through the identity information verification module. When the verification result is that the identity list information contains identity information, the access control control unit determines whether there is corresponding travel instruction information based on the identity information index. If there is no corresponding travel instruction information, the access control control unit directly contacts the access control status and allows the executor to pass. If there is corresponding travel instruction information, the access control control unit sends the target area location information in the travel instruction information to the smart mobile terminal. In actual use, the smart mobile terminal has two states, one is that it has received travel instruction information and is in the task execution state, and the other is that it has not received travel instruction information and is in the task not execution state. For the smart mobile terminal in the task not execution state, the access control unit only verifies the identity information of the smart mobile terminal. After the verification is passed, the access control can be lifted to allow the executor corresponding to the smart mobile terminal to pass. For the smart mobile terminal in the task execution state, the access control control unit first verifies the identity information of the smart mobile terminal. After the verification is passed, the target area location information is sent to the smart mobile terminal to verify whether it has completed the task of reaching the target area location survey. Then, based on the verification result feedback from the smart mobile terminal, it is judged whether the executor has completed the task, and then it is decided whether to lift the access control for the executor.

[0027] The beneficial effects of the present invention are: the present invention provides a community security system based on the Internet of Things, which can be used for property management in existing communities. The manager sends patrol tasks to the smart mobile terminal carried by the security guard through the management terminal, and then uses the access control unit to verify the completion of the security guard's patrol task, and decides whether to contact the access control for the security guard who undertakes the patrol task based on the verification result. At the same time, the travel verification process is placed in the smart mobile terminal for verification, and the executor's travel trajectory is not sent to the access control control unit. On the basis of ensuring the confidentiality of the executor's travel trajectory, it is guaranteed that all patrol trajectory information will not be leaked at the same time, thereby improving the confidentiality and safety of community security work.

The executor then feeds back the verification result to the access control unit through the smart mobile terminal. The access control control unit determines whether the executor has reached the target area and completed the travel instruction information based on the travel trajectory verification result, and then decides whether to release the access control for the executor based on the verification result.

[0038] Specifically, the management terminal inputs the target area location information tagged with the corresponding identity information preset in the smart mobile terminal to the access control unit. In actual application, the management terminal can simultaneously send different travel instruction information to multiple smart mobile terminals.

[0043] Specifically, when the verification result fed back to the access control control unit is that the travel trajectory involves the location information of the target area, the access control control unit controls the release of access control.

[0044] Specifically, when the verification result fed back to the access control unit is that the travel trajectory involves the target area location information, the verification result is passed; when the travel trajectory does not involve the target area location information, the verification result is failed.

[0045] Specifically, when the verification result fed back to the access control control unit is that the travel trajectory does not involve the target area location information, the verification result is failed, and the access control control unit maintains the access control enabled state.

[0046] Specifically, when the identity information verification module verifies the received identity information and the identity list information, and the verification result is that the identity list information does not contain the identity information, the verification result fails, and the access control control unit does not send the target area location information to the smart mobile terminal, and keeps the access control enabled.

[0047] Specifically, the identity information verification module verifies the received identity information and the identity list information. When the verification result is that the identity list information contains the identity information, the verification result is passed, and the access control unit can send the target area location information to the smart mobile terminal.

[0048] Specifically, the access control unit includes a prompt module, and the prompt module is used to display verification information.

Then, based on the verification result feedback from the smart mobile terminal, it is judged whether the executor has completed the task, and then it is decided whether to lift the access control for the executor.

[0052] When in use, the community security system is placed in the community property security management environment. The manager controls the management terminal, and each security personnel is equipped with a smart mobile terminal. The manager first formulates the security personnel's scheduling information, that is, the identity list information of the security personnel corresponding to a certain time period, and then inputs the identity list information of the working time period into the access control unit through the management terminal, so that the security personnel in the working time period can interact with the access control unit through the identity information in the smart mobile terminal when they are not performing patrol tasks, and realize free passage through the access control. The security personnel who are not in the working time period, after sending their identity information to the access control control unit through the smart mobile terminal, the access control unit will not be affected by the identity list information received. If the identity information is included, the access control will not be released for the security personnel, so as to avoid the situation that the security personnel can pass through the access control at will during non-working hours. When the manager receives a message that the security personnel are required to patrol the designated area, the management terminal sends a travel instruction information to the smart mobile terminal of a security personnel through the management terminal. The travel instruction information includes the location information of the area, that is, the target area location information, instructing the security personnel to receive the travel instruction information through the smart mobile terminal to go to the target area to complete the patrol task. At the same time, the management terminal is used to input the target area location information and the identity list information of the security personnel into the access control unit. When the security personnel returns after completing the task, the access control unit completes the situation of the security personnel's travel instruction information. Specifically, the access control unit first verifies the identity information of the security personnel, and the security personnel sends the identity information to the access control unit through the identity information sending module in the smart mobile terminal. The access control unit receives the identity information through the identity information receiving module, and verifies the received identity information with the identity list information through the identity information verification module to verify whether the identity information of the security personnel is in the working time period. After the verification is passed, the access control unit determines whether there is corresponding travel instruction information based on the identity information index. If there is no corresponding travel instruction information, the access control unit directly contacts the access control status and allows the security personnel to pass. If there is corresponding travel instruction information, the access control unit sends a message to the smart mobile terminal. The terminal sends the target area location information in the travel instruction information. After the security personnel's smart mobile terminal receives the target area location information, it compares and verifies the travel trajectory with the target area location information through the location information verification module. It verifies in the smart mobile terminal whether the security personnel has reached the target area for patrol. The verification result is fed back to the access control unit through the smart mobile terminal. The access control control unit determines whether the executor has reached the target area and completed the travel instruction information based on the travel trajectory verification result, and then decides whether to release the access control for the executor based on the verification result. If the travel trajectory involves the target area location information, it indicates that the security personnel has completed the patrol task, and the access control control unit controls the release of the access control to allow the security personnel to pass.If the travel trajectory does not involve the location information of the target area, it means that the security personnel have not completed the patrol task. The access control unit will keep the access control open, allowing the manager and the security personnel to communicate directly, effectively improving the confidentiality and safety of community security work.
