How to quickly determine the performance of the access controller

Looking to see how to cut - how to quickly determine the performance of the controller - Shenzhen City, China Innovation and Automation System Co., Ltd. access controller for the importance of the entire access control system I will not repeat, the access controller is like the heart of the people, the system The soul, on the whole, is the selection of a good access controller, which not only saves engineering costs, extends the life of the entire system, but also facilitates later maintenance and system expansion.

Many articles on how to select access controllers were referenced on the Internet and found that most of the updates were relatively small. Many of them were so-called standards two or three years ago. Actually, after several years of technological innovation and product upgrading, Already an entry-level requirement. The author has been engaged in the industry for many years, and has also written some of his own experience in selecting products for the access control. Now I've put some new things in order. I'll re-paste this article again, and it will be considered revisited by the old tune. I am also disappointed by the expectations of you. Axe is positive. Hope: The stable controller kanban will show a lot of clues. Many so-called brand controllers like to use the shell frame to be strict, leaving only a few interfaces outside. Some customers only saw the shell, and the salesperson's bragging was faint. As everyone knows, to ensure the stability of the controller, you must make efforts on the board.

1: The amount of board components, PCB (circuit board) layers must ensure four or more layers, to maximize the resistance to interference from a variety of sources, I believe that long-term use of security equipment have been It is impossible to ignore the fact that unclear problems such as faults and disturbances have caused a bleak experience, and the possibility of eliminating all kinds of interference to the maximum extent is not to be overlooked.

2. Look at the main chip. Generally speaking, it is necessary to meet the requirements of high efficiency, rapidity, and expandability. 32-bit ARM AT91 series are the mainstream configurations.

3: Look at the above components, relay capacity, protection devices such as surge protection and over-voltage and over-voltage protection, etc., and no less, but also can reflect high performance, such as access control controller, although it is used in civilian facilities Most are on the list, but the standards must be industrial grade. Many manufacturers' products look very refined. During the installation process, the construction staff accidentally picks up the wrong board, or it is a thunderstorm and the entire system is destroyed. .

4: The true industrial-grade standard is that the chips are small and the terminals are all subject to the cruel test of extreme conditions. Many manufacturers just say that one or two components meet the industrial standard and say that their products are industrial. The level will only attract the skepticism of the insiders. Wen: The old saying goes, "The wine is not afraid of the deep alley." The products that can truly stand the test of the market will surely gain a good reputation. Please note that I am not advocating certain brand names here, because the industry itself is chaotic, and the well-known and unknown ones also look at the depth of user contact in this area. The key is to look at the negative reactions in the market. As the saying goes, there are no winds and no waves. No matter if it is a well-known brand, there are as many negative reactions as positive reactions, or even negative reactions are more positive than positive ads. Q: This is mainly to remind the purchaser must first understand their own needs and products actually have the function, although some brands exist in the market for a relatively long time, but their own development strength is limited, a few simple features, several As one day's sales, guests have new needs that cannot be met. There is only a reputation for being an old brand. Pulling out special applications for special occasions does not say that the basic functions of an access controller can be summarized as:

Whether the data is actively uploaded in real time ensures that the information in the management center is updated in real time and the data is accurate, that is, whether or not the communication of the controller is a true TCP/IP network communication.

The diversity and flexibility of door opening methods such as normally open, normally closed, password, card + password, card or password, multi-card opening, first card door, first card startup, and personalization such as switch control, office mode, etc. ensure that When the requirements of the management area are diverse, it can be freely set as needed.

Is there an easy way to configure and authorize the system? Because many of the controllers I know are very cumbersome and time consuming for the configuration and personnel authorization of large-scale systems. It is advisable to have the template function and authorization through the batch or group. The functional controller is equipped with a flexible personnel data import function, which can greatly save the time for the project commissioning personnel.

With regard to the degree of flexible response to individualized demands, the current access control projects and the needs of customers are varied, and the competition can be said to be fierce. It is natural to find a product that can quickly meet the individual needs of customers and can guarantee to the engineering company and integrator. Providing sufficient profits can enhance its competitive strength and take the market first.

The openness of the system, many integrated projects usually involve secondary development, can provide easy to use the secondary development interface and protocol for integrators to consider this condition.

Others, such as the reader above the LED and buzzer sound and light response output, the life of the flash are required to understand to balance the overall performance of the product.

Cut: It is better to see one hundred words, one question is better than one try, the so-called "cut" is the actual operation and testing of the function and performance of the access controller. Access controller manufacturers generally provide customers with a certain test cycle, readers should not ignore this clause, the real confidence in the product manufacturers usually encourage customers to conduct product testing, and for some test methods can provide some professional advice, such as The author understands that Mays access control can provide up to three months of test cycles for new customers, as well as test tools and test methods (power supply short-circuit, reverse connection, port misconnection, wide voltage and other stress test limit numbers, Configuration, etc.) If the test is not satisfactory, or if the product is damaged due to the test, the test deposit will be refunded in full. The test should also include functional testing and compatibility testing, and then find a few small projects that are actually used on the project site. After such a test process to select a product, the problem will not be a big problem. . The author is personally looking forward to more appearances of this type of manufacturer, and it can be regarded as a boon for the engineering and integrators.

The above is a personal one-of-a-kind view, but please also have more professionals in this area to provide additional opinions. The history of the access control industry and the entire security industry itself is not long, there are not many standards for reference, and some new requirements and standards emerging from actual projects also require experts who are committed to the security access control industry. Educated us, many exchanges. Let the entire industry and market can be standardized, and revitalize national brands. I will continue to absorb new ideas and update this article in a timely manner.
