[0002] At present, most door locks on the market still use traditional key locks. However, with the progress of technology, more and more intelligent door locks have emerged on the market. However, the existing door locks do not have a good experience in the overall design and the control of the diversification of unlocking methods.

[0003] In recent years, CAT1 has gradually emerged and become an emerging technology in China. However, it is normally used in non-low-power-consumption scenarios. Although CAT1 does not have the function of low power consumption, the CAT1 base stations are widely distributed and basically no new construction is required. At the same time, it has the function of rapid network access. Therefore, how to apply CAT1 to door locks and realize the power-on and power-off operations of the CAT1 module through corresponding technologies to achieve normal communication and energy-saving work has become one of the difficulties that each enterprise needs to overcome.

[0005] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0006] An intelligent door lock based on CAT1 includes a door lock body, on which a password button input module, a CAT1 module, an MCU, and a power module are provided; the password button input module is arranged on the front of the door lock body, and the CAT1 module, the MCU, and the power module are arranged inside the door lock body; the password button input module, the CAT1 module, and the power module are all electrically connected to the MCU. Among them, the CAT1 module is controlled by the MCU, and the MCU controls the power-on and power-off operations of the CAT1 module to achieve the normal communication and energy-saving operation of the CAT1 module.

[0007] Further, the power module uses a power storage battery, and the power storage battery provides a standard voltage of 3.3V; and the power storage battery adopts a detachable structure.

[0008] Further, the MCU controls the CAT1 module through an electronic control module, and the electronic control module is electrically connected to the MCU and the CAT1 module;

[0009] Specifically, the electronic control module includes resistors, capacitors, polarized capacitors, and MOS transistors.

[0011] Further, the capacitor C134 and capacitor C139 adopt NC moisture self-charging regulated supercapacitors.

[0012] Further, for the connection between the MCU and the electronic control module and the CAT1 module, ordinary external pins of the MCU can be used.

[0015] 2. The intelligent door lock of the present utility model is based on CAT1 technology. When communication is required, power is supplied to the CAT1 module to start rapid network access. Once the network access is successful, the communication task is immediately completed. As long as it is not a special command, the network is directly disconnected without waiting. If it is a special command, the network connection is maintained for 15 seconds to wait for the downstream task. After 15 seconds without other instructions, the CAT1 module is powered off, and the whole machine system enters the low-power operation state.

[0016] 3.

[0020] The following further describes the utility model in conjunction with the drawings and specific embodiments. Those parts not described in the text can be implemented by using conventional technical means in the art, so they will not be elaborated here.

[0021] As Figure 1 、 Figure 2 shown, an intelligent door lock based on CAT1, characterized in that it includes a door lock body, and a password button input module, a CAT1 module, an MCU and a power module are arranged on the door lock body; the password button input module is arranged on the front of the door lock body, and the CAT1 module, the MCU and the power module are arranged inside the door lock body; the password button input module, the CAT1 module and the power module are all electrically connected to the MCU, wherein the CAT1 module is controlled by the MCU, and the MCU controls the power-on and power-off operations of the CAT1 module to realize normal communication and energy-saving operation of the CAT1 module.

[0022] The MCU controls the CAT1 module through the electronic control module, and the electronic control module is electrically connected to the MCU and the CAT1 module. Specifically, the electronic control module includes resistors, capacitors, polarized capacitors and MOS transistors; among them, one end of the resistor R106, one end of the capacitor C131 and the source electrode of the MOS transistor Q8 are connected together to the positive pole of the power module, the other end of the resistor R106 and the gate electrode of the MOS transistor Q8 are connected together to the MCU, and the other end of the capacitor C131 is grounded; the drain electrode of the MOS transistor Q8 is connected to one end of the capacitor C130, one end of the capacitor C132, the positive pole of the polarized capacitor C137, the positive pole of the polarized capacitor C138, one end of the capacitor C136, one end of the capacitor C135, and one end of the capacitor C133 to connect to the CAT1 module, and the other end of the capacitor C130, the other end of the capacitor C132, the negative pole of the polarized capacitor C137, the negative pole of the polarized capacitor C138, the other end of the capacitor C136, the other end of the capacitor C135, and the other end of the capacitor C133 are grounded.

Naturally, the USB charging function can also be incorporated to better meet the power supply requirements for switching the intelligent door lock in case of emergency. For those not described in this solution, such as the specific motor of the intelligent door lock and the possible intelligent door card design, etc., conventional technical means can be used for implementation, so they will not be elaborated here.
