Description

Technical Field

[0001] The present invention relates to the technical field of access control systems, and more particularly, to a relay type access control power supply control system and method. Background Art

[0002] In an access control system, the performance of the power supply is particularly important, and the selection of the power supply directly affects the safety and stability of the access control system. For existing access control power supplies, in order to continue to provide access control functions when there is a mains power failure, a backup power battery is generally added to the power supply module, and the backup power battery is a lithium battery or a nickel-metal hydride battery. The configuration method usually provides the output bus of the AC-DC power conversion module to the subsequent access control system load and the backup battery for charging in a branch manner. Usually, the output power of the AC-DC power conversion module is designed according to the total power of the dynamic maximum current of the load and the maximum charging current of the backup battery to ensure the normal operation of the access control system. Nowadays, many access control systems are equipped with high-performance face and various biometric machines, and their instantaneous current peaks are high, resulting in a large dynamic power consumption, and general power supplies cannot support large dynamic currents.

[0003] The existing solution is to increase the power of the AC-DC power supply. The AC-DC module needs to be designed according to the dynamic peak current + charging current to meet the situation of large dynamic current. However, such a design is difficult to control the cost and volume, increases the production cost and the volume of the power supply, and there is also power redundancy.

[0004] In view of this, the present invention proposes a relay type access control power supply control system and method that can meet occasional large currents and has a low cost. Summary of the Invention

[0005] The object of the present invention is to propose a relay type access control power supply control system and method that can meet occasional large currents and has a low cost.

[0006] A relay type access control power supply control system includes a conversion circuit, a charging circuit, a power supply battery, a load circuit, and an access control controller, and is characterized in that: the output end of the conversion circuit is connected to the input end of the charging circuit, the output end of the charging circuit is connected to the input end of the power supply battery, the output end of the power supply battery is connected to the input end of the load circuit, the output end of the load circuit is connected to the input end of the access control controller. The conversion circuit is used to convert the input power into an adapted voltage, the charging circuit is used to charge the power supply battery, the load circuit is used to supply power to the access control controller, and the access control controller is used to perform access control operations.

[0007] In some embodiments, the conversion circuit is an AC-DC conversion circuit.

[0009] In some embodiments, the power supply battery is further connected to a battery power detection circuit, which is used to detect the real-time power of the power supply battery. When the power is lower than the set value, a low power warning message is generated and sent to the access control controller, and the access control controller outputs it to an externally pre-bound device.

Description of the Drawings

[0015] Figure 1This is a schematic structural diagram of a relay type access control power supply control system of the present application.

[0016] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. Specific Embodiment

[0017] The following embodiments are described to assist in understanding the present application. The embodiments are not and should not in any way be construed as limiting the scope of protection of the present application.

[0018] In the following description, those skilled in the art will recognize that throughout this discussion, components may be described as separate functional units (which may include sub-units), but those skilled in the art will recognize that various components or portions thereof may be divided into separate components or integrated together (including being integrated within a single system or component).

[0019] At the same time, the connections between components or systems are not intended to be limited to direct connections. Instead, data between these components may be modified, reformatted, or otherwise changed by intermediate components. Additionally, additional or fewer connections may be used. It should also be noted that the terms "coupled", "connected", or "input" should be understood to include direct connections, indirect connections through one or more intermediate devices, and wireless connections. Embodiment 1:

The conversion circuit is used to convert the input power into an adapted voltage, the charging circuit is used to charge the power supply battery, the load circuit is used to supply power to the access control controller, and the access control controller is used to perform access control operations.

[0021] The conversion circuit is an AC-DC conversion circuit.

[0022] Specifically, the AC-DC conversion circuit is connected to the power supply battery through the charging circuit. The power supply battery is connected to the access control controller through the load circuit. The AC-DC conversion circuit provides power supply for this embodiment, charges the power supply battery through the charging circuit, and the power supply battery provides the voltage and current required by the load circuit. Since the load circuit is only connected to the output terminal of the power supply battery, the required working power all comes from the power supply battery. Under the action of an appropriate charging current in the charging circuit, plus the large dynamic current of the access control is only used occasionally (such as ≤50 times of triggering per day), in fact, most of the time is used to charge the power supply battery, which can not only meet the occasional large dynamic current of the access control load circuit, but also make the AC-DC conversion circuit relatively small in power and volume, achieving the effect of cost reduction and efficiency improvement.

[0023] The access control controller circuit is also connected to the power consumption information detection circuit. The power consumption information detection circuit is used to detect the power consumption information of the access control during door opening, door closing, face recognition, and biometric recognition, so as to extract the door opening and closing records of the access control system.

[0024] The power supply battery is also connected to a battery power detection circuit. The battery power detection circuit is used to detect the real-time power of the power supply battery. When the power is lower than the set value, a low-power alarm message is generated and sent to the access control controller, and the access control controller outputs it to the externally pre-bound device.

[0026] The conversion module is an AC-DC conversion module.

[0027] The access control controller module is also connected to a power consumption information detection module. The power consumption information detection module is used to detect the power consumption information of the access control during door opening, door closing, face recognition, and biometric recognition, so as to extract the door opening and closing records of the access control system.

[0028] The power supply battery module is also connected to a battery power detection module. The battery power detection module is used to detect the real-time power of the power supply battery module. When the power is lower than the set value, a low-power alarm message is generated and sent to the access control controller, and the access control controller outputs it to the externally pre-bound device.

[0029] Although the present application has disclosed multiple aspects and embodiments, other aspects and embodiments will be obvious to those skilled in the art. Without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application.
