Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic lock technology, and specifically refers to an electronic lock system. Background Technology
[0002] Key-based electronic locks combine modern electronic technology to provide a safer, more convenient, and more efficient locking solution. They achieve intelligent management of the lock through a built-in microprogram controller (MCU). Users can authenticate their identity using preset passwords, fingerprints, RFID cards, and other methods to unlock the lock. Furthermore, key-based electronic locks feature multiple security protection functions, including anti-pry and anti-technical unlocking features, significantly enhancing the lock's security performance.
[0003] Existing key-based electronic locks on the market (including those with card swiping, touch buttons, and biometric features such as fingerprints) have relatively high power consumption, resulting in poor battery life and frequent maintenance (battery replacement and charging). This leads to high maintenance costs and a poor user experience. Furthermore, most key-based electronic locks typically use photosensors to collect ambient light. Due to the influence of photocurrent, the power consumption of the collection circuit is relatively high. At the same time, because there is no function to switch the operating mode of the collection circuit, the range of light intensity that can be collected is not wide enough; it can only collect light intensity in either low or high illuminance, and cannot simultaneously collect light intensity in both high and low illuminance environments. Utility Model Content
[0004] The main purpose of this invention is to provide an electronic lock system that solves the problems existing in the prior art, reduces the impact of photocurrent of photosensitive sensor on lock power consumption, and is compatible with light intensity acquisition under both high and low illumination.
[0005] To achieve the above objectives, the solution of this utility model is:
[0006] An electronic lock system includes a lock and a controller. The lock includes a microprogram controller, a photosensitive sensor, a photosensitive control module, a key module, and a power supply. The photosensitive sensor is used to collect the ambient light intensity around the lock and send an illuminance signal. The photosensitive control module has several acquisition circuits corresponding to different illuminance levels, and the illuminance signal sent by the photosensitive sensor is transmitted to the microprogram controller through one of its acquisition circuits. The microprogram controller receives the illuminance signal and switches the acquisition circuit of the photosensitive control module according to a preset light threshold. The key module is signal-connected to the controller to implement the relevant functions of the lock. The power supply provides power.
[0007] The photosensitive sensor is a photoresistor, a phototransistor, a phototube, or a photomultiplier tube.
[0008] The lock also includes a key control module electrically connected to the key module; the key module has different power consumption operating modes, and the key control module is used to switch the operating modes of the key module; the microprogram controller sends a corresponding control signal to the key control module according to a preset light threshold to achieve the switching of the operating modes of the key module.
[0009] The types of locks include NFC locks, combination locks, fingerprint locks, and iris locks.
[0010] The power source is a built-in battery, an external battery, or an external power cord.
[0011] The photosensitive control module's acquisition circuit is divided into three levels based on two preset illumination thresholds: low illumination acquisition circuit, medium illumination acquisition circuit, and high illumination acquisition circuit.
[0012] The acquisition ranges of the low-illuminance acquisition circuit, the medium-illuminance acquisition circuit, and the high-illuminance acquisition circuit increase sequentially.
[0013] After adopting the above technical solution, the present invention has the following technical effects:
[0014] This invention integrates a photosensitive sensor and its photosensitive control module into the lock. The photosensitive control module has several different acquisition sub-circuits. Based on the light intensity signal corresponding to the ambient light intensity around the lock acquired by the photosensitive sensor, the microprogram controller can automatically and flexibly switch the acquisition circuit of the photosensitive sensor. This allows for compatibility with light intensity acquisition under both high and low illumination conditions, achieving a wider light intensity acquisition range. This invention enables adaptive switching of the photosensitive sensor's acquisition circuit, simultaneously meeting the light intensity acquisition requirements under both high and low illumination conditions while reducing the power consumption of the lock.

[0020] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0021] refer to Figure 1 As shown, this utility model discloses an electronic lock system, including a lock 1 and a controller 2;
[0022] The lock 1 includes a microprogram controller 11 (MCU), a photosensitive sensor 12, a photosensitive control module 13, a key module 14, and a power supply 15;
[0023] The microprogram controller 11 is programmed with a pre-set control program for the lock 1;
[0024] The photosensitive sensor 12 is used to collect the ambient light intensity around the lock 1 and send an illuminance signal;
[0025] The photosensitive control module 13 has several acquisition circuits corresponding to different illuminances. The illuminance signal sent by the photosensitive sensor 12 is transmitted to the microprogram controller 11 through one of its acquisition circuits. The microprogram controller 11 receives the illuminance signal and switches the acquisition circuit of the photosensitive control module 13 according to the preset illuminance threshold.
[0026] The key module 14 is connected to the controller 2 via signal (including contact and non-contact methods) to realize the lock 1's functions such as opening and closing, and changing the password;
[0027] Power supply 15 is used for power supply.
[0028] Through the above scheme, this utility model has a built-in photosensitive sensor 12 and its photosensitive control module 13 on the lock 1. The photosensitive control module 13 has several different acquisition sub-circuits. According to the light intensity signal corresponding to the ambient light intensity around the lock 1 collected by the photosensitive sensor 12, the microprogram controller 11 can automatically and flexibly switch the acquisition circuit of the photosensitive sensor 12. It can be compatible with high and low light intensity acquisition and realize a large light intensity acquisition range. Specifically: (1) When the ambient light intensity signal is detected to be less than the light threshold of the weak light environment (<2LUX), the photosensitive sensor acquisition circuit with low light intensity acquisition is more ideal; (2) When the ambient light intensity signal is detected to be between the light threshold of the weak light environment and the light threshold of the strong light environment (2~30LUX), the photosensitive sensor acquisition circuit with medium light intensity acquisition is more ideal; (3) When the ambient light intensity signal is detected to be greater than the light threshold of the strong light environment (>30LUX), the photosensitive sensor acquisition circuit with high light intensity acquisition is more ideal. The above enables the present invention to achieve an adaptive switching acquisition circuit for the photosensor 12, which can simultaneously meet the light intensity acquisition requirements under high and low illumination conditions while reducing the power consumption of the lock 1. Specifically, refer to Figure 2As shown, the electronic lock initially uses a low-illuminance acquisition circuit (low power consumption, small acquisition range) by default. When the illuminance exceeds the range of the low-illuminance acquisition circuit, a switch selects a medium-illuminance acquisition circuit (medium power consumption). When the illuminance exceeds the range of the medium-illuminance acquisition circuit, a switch selects a high-illuminance acquisition circuit (higher power consumption, larger acquisition range). Some circuits consistently use the high-illuminance acquisition circuit, resulting in high power consumption and inaccurate low-illuminance detection. This solution reduces power consumption while providing more accurate detection.
[0029] The following are specific embodiments of the present invention.
[0030] The aforementioned photosensitive sensor 12 can be a photoresistor, a phototransistor, a phototube, a photomultiplier tube, etc.
[0031] The aforementioned lock 1 also includes a key control module 16 electrically connected to the key module 14; the key module 14 has different power consumption operating modes, and the key control module 16 is used to switch the operating modes of the key module 14; in addition to switching the acquisition circuit of the photosensitive control module 13, the microprogram controller 11 also sends a corresponding control signal to the key control module 16 according to a preset light threshold to switch the operating mode of the key module 14 (the light threshold for switching the acquisition circuit is not necessarily the same value). Therefore, depending on different ambient light levels, the key module 14 can be switched to standby or operating mode. Especially when the ambient light level is consistently low, it can be basically determined to be an unoccupied environment, allowing the lock 1 to remain in standby mode for a long time, thereby reducing power consumption. Specifically, refer to... Figure 3 As shown, when the change in ambient light intensity exceeds the light intensity judgment threshold, the MCU controls the power supply of the key module 13 through IO, turning off the power supply of the key module 13 to reduce power consumption; or the module power supply is not turned off, and the MCU and the key module communicate to reduce the module's transmission power or reduce the operating frequency through control commands.
[0032] The types of locks 1 mentioned above include, but are not limited to, NFC locks, combination locks, fingerprint locks, iris locks, etc. Therefore, the signal connection methods between the key module 14 and the controller 2 include, but are not limited to, swiping a card, touching a button (entering a password), touching a fingerprint collector, and looking at an iris collector. The corresponding controller 2 types are NFC cards, button panels, fingerprint collectors, iris collectors, etc.
[0033] The power source 15 can be a built-in or external battery, or an external wire. Generally, a built-in battery is preferred.
[0034] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
