There are also many public areas such as factories and parking lots, important telecom base stations, and intelligent motor control. Intelligent access control system is applying to different fields.

Network Pains:

Intelligent access control system is inseparable from network support, at least between indoor unit and outdoor unit request network connection. Well, traditional network connection mainly relies on network cable transmission, such as CAT5E / CAT6 network cable, wireless WI-FI transmission, Bluetooth transmission, etc.

Extensive market demand rises to a large number of users’ needs for the renewal and transformation of access control systems. However, the replacement of access control systems faces a big problem, that is, except newly developed buildings, the old buildings or other application scenarios, access control almost haven’t the conditions for network wiring.

That means if you use wireless or Bluetooth access control to transmit signals, in case the distance between the outdoor and the indoor unit is a little far away, or there is a partition wall, the signal will be greatly attenuated. If use the wiring network cable, will cause increased cost of the network cable, as well as the construction cost.

Power line Communication (PLC) PROS:

At this time, Powerline communication (PLC) technology is a high-quality option for upgrading and replacing access control. The low-cost 200Mbps PHY Rate PLC solution can fully meet the network support in common scenarios.

The working voltage is DC12V, which is very convenient to take power.

7LP120 is a powerline communication module device more suitable for retrofitting old access control. It has an ultra-thin design with a thickness of up to 8mm. (In the case of the limited volume of the original access control), the ultra-thin and pin design has a thickness of up to 8mm. 8mm, suitable for PCB embedding in the small space of the original access control .

In addition, 7LP120 supports PLC filtering, overcurrent and lightning protection, and customers can choose freely. 7LP120 also supports fault self-recovery function, which improves the reliability of product operation.

Cons:

Of course, the use of Powerline communication (PLC) products in the access control system also have some restrictions and requirements, mainly related to its technical characteristics. Because PLC uses high-frequency signals to transmit data, part of the frequency of switching power supply and PLC signal transmission frequency part overlap, so switching power supply,  voltage regulator and other electrical appliances may affect the transmission of signals. In addition, electrical appliances in the grid / Too many devices/long distance between modules/   old quality wires, the non-standard overlapping of power lines, etc., will affect the signal transmission.

Therefore, before purchasing and installing, you can communicate with the supplier about the use requirements. According to different specific needs, manufacturers choose models reasonably to meet the needs of users to the greatest extent.

Introduction:

PLC, or power line communication, is a method of transmitting data over a power line. PLC is an essential component of the smart grid because it can be used to implement bidirectional communications over existing power distribution networks.

PLC, or power line communication, is a method of communication that employs electrical currents as a transmission medium. Building a system using power lines as the communication network can be done rapidly and cheaply.

This is why PLC is used for communications in the various energy management systems that make up a smart society, such as smart meters (advanced metering infrastructure – AMI), HEMS, BEMS, and solar panel monitoring systems. Electrical current, either alternating or direct, can carry information in a network.

Fire and security alarms, smart lighting, building energy management systems, and solar farms can all benefit from the lower wiring costs made possible by the Powerline Communication solution providers by transmitting data over existing AC and DC power lines.

Types of Power Line Communications:

• Narrowband PLC: Narrowband programmable logic controllers (PLCs) operate at frequencies between 3 and 500 kilohertz. The distance they can travel is several kilometers, but the data rate is very slow. The Smart Grid depends on them.
• Broadband PLC: Broadband PLCs operate at speeds of over 100 Mbps and frequency ranges of 2–250 MHz. They are employed at close quarters. You can use them to automate your house.

Applications of Power Lines:

1. Home Networking (LAN): LAN connections in the home can be made using the building’s existing electrical wiring rather than installing new cables. An Ethernet port is required for the devices to communicate. When a power line adapter is plugged into a wall outlet, it creates an ethernet connection.
2. Broadband over power lines (BPL): It uses the alternating current (AC) electrical distribution wiring between transformers to send and receive signals in both directions, and the alternating current (AC) low voltage wiring between transformers and customer outlets to transmit signals in both directions.
3. In-vehicle network communication: In cars, digital signals travel along the battery cables, which carry direct current.

Applications for Power Line Communication Solutions:

PLC Evaluation Tools

It is important to evaluate the state of communications when using power lines because of potential interference from noise and line impedance.

Technical Standards

It is anticipated that the complexity and scale of PLC networks will increase with the proliferation of smart meters and other smart devices. Several international groups are working to ensure compatibility between these various networks by standardising and developing profiles for communication protocols.

How does power line communication work?

Technology called “Power Line Communication” (PLC) allows for data transmission through the electrical power lines themselves. This means that it is possible to provide power and half-duplex control/data retrieval to an electronic device (for example) using only the power cables.

Where is power line communication used?

In power line communications (PLCs), data is transmitted over standard, low-voltage power lines. Some utilities have already begun using PLC for remote metering and load control. Since the power lines already extend to the meter, it is easily incorporated into the smart metering system.

Elevator Monitoring Pains:

The installation difficulty of the elevator video monitoring for the engineers is mainly due to the difficulty in wiring. Although the wireless bridge scheme commonly used in the market has solved the cabling problem, while the signal is unstable, it is easy to drop wires and lose packets. The effect is not ideal.

Powerline Transmission Solution:

Working principle: Use the original line of the elevator to load the network (TCP/IP protocol) video or other network signals of the terminal equipment such as the camera/digital screen in the car to 7HP200 or 7ZX150, after modulation, through OFDM carrier technology , use the video line of the elevator travelling cables to transmit the signal to another 7ZX150 on the platform on the elevator shaft, and then transmit the video and other signals to the host computer in the monitoring room after modulation and demodulation.

Since 7ZX150 has the function of filtering and anti-interference, it can perfectly solve various strong electromagnetic interference and noises on signal transmission caused by heavy-duty variable-frequency motors from the shaft to the car, strong current switch surges, and high-frequency signal generators during the operation of the elevator. interference to achieve stable signal transmission.

Installation method: Install a 7ZX150 on the platform of the elevator shaft. In the middle, use the elevator travelling cables to find the video cable, install a 7HP200 or 7ZX150 in the car, and connect it with the network camera to achieve the purpose of stably transmitting network video and other signals.

Features&Benefit:

Stable operation and easy installation;

Multi purpose: 

This scheme is not only used for video monitoring, but also for transmission of any data, such as elevator status monitoring/diagnosis, video intercom, equipment signal transmission, etc.

Any equipment and set up like a home theater or other gadgets can seamlessly interface with a powerline adaptor utilizing an ethernet link, over your home’s electrical or to a second powerline adapter connected to another area.

It is associated with your switch utilizing an Ethernet link. Interfacing your streaming gadgets and switching to powerline adaptors is practically similar to connecting them utilizing ethernet links. With the expanded number and utilization of gadgets that can interface and move digital media across devices in a home or office, utilizing a customary wired Ethernet network to get to data and documents all through the space can be full of hassles.

Powerline adaptors can be beneficial to use in many ways

In cases like this, powerline adaptors can be the perfect answer as long as you are aware of their benefits and restrictions as well as the added security it provides. Wi-Fi is very helpful, but it unquestionably has its deficiencies. Even though powerline adaptors have so many features, they also offer unwavering quality that wireless technology still can’t compare with. Powerline adaptors work depending upon the electrical wiring in your home.

A powerline adaptor can send information over your current electrical wiring very much as it would over Ethernet links – all you want is an electrical plug. It is not difficult to set up a powerline adapter by 7inova, Ethernet links, and no less than two powerline adapters (PLC). One of the adapter must be connected to the electrical plug closest to your router and interface with it utilizing an Ethernet link.

Utilize different adaptors for every gadget you need to connect. The main component that you must consider while buying a powerline connector is its speed. Powerline adaptors are prone to less data loss and stable transmission over normal Wi-Fi. Powerline adaptors use your home’s electrical wiring to move data.

Powerline units can additionally be password secured, adding a layer of protection. Powerline units are great for enormous spaces with numerous floors. Many would select Wi-Fi extenders at this point, but powerline adaptors can provide a better network through thick floors and walls. Much of the time, powerline connectors offer a speed identical to that of Ethernet links, so it’s more dependable than WiFi. Furthermore, powerline adaptors are turning out to be increasingly cost-efficient, so they’re a superb choice for individuals who want to experience the advantages of a wired network without managing links. 7inova offers ODM powerline modules, ready-to-use devices, and home-use powerline adaptors.

I recently wechat in a group, one friend is curious about my power line module image, asked what it is and what is it for. I explained: It is a kind of embedded module, make use of power line carrier communication technology, realize network transmission for such as underwater drone, intercom, security camera ect.

Friend still didn’t quite understand what it is and what it is for. I recognized that powerline carrier technology is still not introduced to most  common people. How to make them easily understand why need to use powerline?

Simply put, power line carrier solution is an optional network transmission way where wireless or ethernet cable, fiber are not suitable to use.

For example, underwater drone, underwater camera, they need to do image transmission, but it is not convenient to use cables or wireless under water, right? In this case, powerline is a very ideal choice.

Unlike powerline adapters in home, which are plugged into mains directly, the module form powerline modules are designed to embed into main device, they work under power supply of AC/DC Voltage from main device (Tether board, elevator control board, camera ect) , pair and work plug and play, transfer network signal over the AC/DC power line.

It will be better If I could send some pictures for illustration later. Anyway, For engineers, he will understand the work way better than me. : )
