 Have overseas system integrators and software platform providers with development capabilities noticed that the parameter sheets for QR code access control systems always list "surge protection" as a feature? Today, let's explore the technical insights behind QR code access control's "surge protection".

 How much do you know about the technological wisdom behind the

I、What are the application scenarios of QR code access control "surge protection"?

 Before understanding the application scenarios of QR code access control "surge protection", let's first talk about what "surge" is and its occurrence scenarios.

Surge, in fact, is like a sudden "rapids" in a water pipe, mainly referring to high-voltage pulses that occur instantaneously in an electrical system and exceed the normal operating voltage or current. This type of situation usually occurs at the moment of power grid fluctuations or the start stop of high-power equipment, equipment being struck by lightning, encountering electrostatic interference, etc.

Surge protection "has extremely strong anti surge capabilities and can be successfully applied in scenarios where" surges "are prone to occur, avoiding damage to equipment caused by sudden high-voltage pulses.

As an access control manufacturer that has been deeply involved in QR code access control for nearly 11 years. our developed QR code access control "surge protection" function can easily respond to "surge" risks in various scenarios. Our mature R&D team, with its full chain risk prediction capability, can identify real scenario risks such as lightning strikes, inductive loads, and long-term interference in outdoor deployments in advance. The product has also passed rigorous anti surge testing, ensuring long-term stable operation of the equipment.

 

II、What benefits can QR code access control "surge protection" bring to integrators?
Cyberoce QR code access control system receives CE certification.

 The reason why QR code access control "surge protection" is so important to integrators is that it can reduce equipment failure rates and lower maintenance costs in the later stage. For example, our QR code access control "surge protection" can bring the following benefits to system integrators and software platform providers:

  1. Reduce equipment failure rate and maintenance costs

Our QR code access control "surge protection" has strict quality control, and the product repair rate is also very low. Each product undergoes at least 48 hours of aging testing before leaving the factory. Even in the event of electric shock or nearby large equipment switches, the equipment can resist the impact of high voltage pulses, reducing failure rates and maintenance costs.

  1. Easy for product upgrade

Since its establishment, the company has been specializing in the field of QR code access control. So, our product has strong compatibility. Whether it's a new or old product, the interface is unified and only needs to be docked once. All products can be easily accessed and controlled using QR codes without frequent debugging of interface protocols or complex system adaptation.

 

III、Why can QR code access control "surge protection" play a protective role?

 Are you curious why our QR code access control's "surge protection" can provide reliable protection in so many scenarios? In fact, this cannot be achieved without multiple protective measures. for example:

  1. At the output of the power supply, we add a transient suppression diode (TVS). Its ultra fast response speed can immediately react when encountering a sudden increase in voltage and control the voltage within a safe range, effectively preventing the circuit from being burned out. Moreover, its voltage regulation capability is very precise, with low power consumption and long lifespan.
  2. On the circuit, we also adopt two-stage network port protection. The first stage uses gas discharge tubes (GDT) or varistors (MOV) to withstand large current surges. Although the response is slower, it can discharge most of the current; The second layer uses transient suppression diodes with fast response to stabilize the voltage. By coordinating these two levels, the surge voltage can be gradually reduced step by step.
  3. The RS485 interface also uses transient suppression diodes for protection, mainly to protect signal lines and interface circuits that are particularly sensitive to voltage fluctuations.
