In addition, the character " / " that may appear in this document generally indicates that the related objects before and after it are in an "or" relationship.

[0019] Example 1: like Figure 1 As shown, this embodiment provides a lightweight linkage door lock system for grain warehouses, including: an entry door lock, a grain unloading door lock, and a communication module. The entry door lock is installed on the entry door of the grain warehouse and includes a first control module and an identification and counting module. The grain unloading door lock is installed on the unloading port of the grain warehouse and includes a second control module. Wherein, the identification counting signal output terminal of the identification counting module is electrically connected to the identification counting signal input terminal of the first control module, the control signal output terminal of the first control module is electrically connected to the control signal input terminal of the communication module, and the control signal output terminal of the communication module is electrically connected to the control signal input terminal of the second control module; The unloading signal output terminal of the second control module is electrically connected to the unloading signal input terminal of the communication module, and the control signal output terminal of the communication module is electrically connected to the control signal input terminal of the first control module.

[0020] In practice, when a worker enters the grain warehouse through the entrance door, the identification and counting module identifies and records the number of people in the grain warehouse as 1. At this time, the identification and counting module transmits the identification and counting signal from its output terminal to the input terminal of the first control module, and then from the output terminal of the first control module to the input terminal of the communication module. The output terminal of the communication module transmits the identification and counting signal to the input terminal of the second control module to activate the unloading door lock, closing the unloading port and preventing it from being manually opened. When the unloading door lock is opened and the unloading port is used for grain discharge, the unloading signal is transmitted through the output terminal of the second control module to the input terminal of the communication module. The output terminal of the communication module transmits the control signal to the input terminal of the first control module to activate the entrance door lock, closing the entrance door and preventing it from being manually opened.

[0021] Based on the above disclosure, the lightweight linkage door lock system provided in this embodiment uses a communication module to link the entry door lock and the unloading door lock, thereby enabling the opening and closing of the unloading door lock at the unloading port and the entry door lock at the entry warehouse, preventing the occurrence of safety accidents when there are personnel in the grain warehouse during the unloading operation.

[0022] Example 2: This embodiment provides a lightweight linkage door lock system for a grain silo, including: an entry door lock, a grain unloading door lock, and a communication module.

The identification and counting signal output terminal of the identification and counting module is electrically connected to the identification and counting signal input terminal of the first control module. The control signal output terminal of the first control module is electrically connected to the control signal input terminal of the communication module. The control signal output terminal of the communication module is electrically connected to the control signal input terminal of the second control module. The grain unloading signal output terminal of the second control module is electrically connected to the grain unloading signal input terminal of the communication module. The control signal output terminal of the communication module is electrically connected to the control signal input terminal of the first control module.

The identification and counting signal output terminal of the dual grating module is electrically connected to the identification and counting signal input terminal of the first control module.

[0024] It should be noted that the initial number of people in the grain warehouse is 0. The first and second gratings are set along the direction of the worker's movement. In this embodiment, when the worker enters the warehouse door and his body passes through the first and second gratings in sequence, it means that the worker has entered the grain warehouse, and the number of people in the grain warehouse is increased by 1. At this time, the number of people in the grain warehouse is 1. When the worker leaves the warehouse door and his body passes through the second and first gratings in sequence, it means that the worker has left the grain warehouse, and the number of people in the grain warehouse is decreased by 1. At this time, the number of people in the grain warehouse is 0.

[0025] In one possible implementation, a display module is also included; The display signal input terminal of the display module is electrically connected to the display signal output terminal of the first control module.

[0026] In practice, the identification and counting module in the first control module records the number of people in the grain warehouse in real time, and the display module is used to display the number of people in the grain warehouse in real time.

[0027] In one possible implementation, the communication module is a 4G communication module.

[0028] This embodiment uses a 4G communication module, which can maintain a high and stable transmission rate, is suitable for high-speed data transmission, and can significantly reduce data transmission latency.

[0029] In one possible implementation, the access door lock further includes a first latch and a first drive motor for driving the first latch; The drive signal input terminal of the first drive motor is electrically connected to the drive signal output terminal of the first control module. The first drive motor controls the first latch according to the received drive signal to realize the opening and closing of the entry compartment door.

[0030] In practice, when the first control module receives the unloading signal transmitted by the communication module, it drives the first motor to control the first locking tongue in order to close the entry door.

[0031] In one possible implementation, the grain unloading door lock further includes a second latch and a second drive motor for driving the second latch; The drive signal input terminal of the second drive motor is electrically connected to the drive signal output terminal of the second control module. The second drive motor controls the second locking tongue according to the received drive signal to realize the opening and closing of the grain unloading silo door.

[0032] In practice, when the second control module receives the identification and counting signal transmitted by the communication module, if the number of people in the grain warehouse in the identification and counting signal is greater than 0, the second drive motor is driven to control the second locking tongue to complete the closing of the unloading warehouse door.

[0033] In one possible implementation, a power module is also included; The power supply terminal of the power module is electrically connected to the power supply input terminal of the entry door lock, the grain unloading door lock, and the communication module, respectively.

[0036] In one possible implementation, the alarm module includes an audible alarm and an indicator light; The sound alarm and indicator light are both electrically connected to the alarm signal output terminal of the first control module.

[0037] In practice, when the number of people in the grain warehouse is greater than 0, and the unloading port receives a request to open the unloading door lock, the sound alarm and indicator light will sound to remind that there are workers in the grain warehouse and the unloading port cannot be opened.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
