Interface protection design for edge computing gateways

With the rise of the Internet of Things and the popularity of cloud services, a new computing paradigm — edge computing — is beginning to appear in our field of vision. Edge computing advocates processing data at the edge of the network, thereby reducing system response time, protecting data privacy and security, extending battery life, and saving network bandwidth. Current applications are divided into industrial and automotive applications.

Industrial gateways

Industrial gateway is an indispensable device of the industrial Internet of Things, it is like the nerves of the human body, the perceived various types of information to the brain for processing, the brain through the operation to determine what kind of response to do, and then transmitted by the nerves to the limbs of the whole body. The gateway can collect PLC data, do remote maintenance and download programs, and has the functions of edge computing and protocol parsing. Industrial communication gateways can perform message conversion between various network protocols, and their functions can be implemented by a chip, an embedded device or board, or a stand-alone device.

Industrial Edge Computing Gateway Features:

1. Rich interface, support Ethernet, serial port, CAN port, IO port and other equipment access and Ethernet, 2G/3G/4G full Netcom network access;

2. Embedded hundreds of industrial protocols, supporting more than 99% PLC and the vast majority of industrial equipment access;

3. 8GB local storage + SD card support, support local data cache and offline application;

4. Three-in-one serial port, support RS485/RS232/RS422 three kinds of electrical interfaces;

5. Support edge computing, realize data optimization, real-time response, agile connection, model analysis and other services in the edge node of the Internet of Things, and effectively share cloud computing resources to support simultaneous access of multiple devices;

6. Support DC9~36V wide voltage input, adapt to a variety of complex industrial sites;

Features of the on-board gateway

Due to the particularity of the on-board power supply, all the product power ports taken from the car need to pass the surge load-dump test, Leiditech Electronics provides a professional protection solution for the load-dump test, compared with the industrial gateway, the on-board power supply protection needs are greater.

summary

The interface protection of electronic products needs to use overvoltage protection devices, many engineers realize that they want to use protection devices, but due to improper selection or failure to follow the ESD circuit PCB design principles, resulting in product electrostatic testing or EMC testing does not pass, product verification tests many times, waste of manpower and financial resources, causing product delays to market Things always occur, or over-design, resulting in cost pressure.

Leiditech Electronics specializes in providing customers with EMC design services for electromagnetic compatibility, providing laboratories to do thorough tests, from customers efficient, easy to complete the design, hoping that more customers can quickly pass EMC’s projects and improve product reliability.

Accessories

These accessories are only available to add on to your package order. The shipping is just not worth it for these small items and should be available wherever you live.

Of course, if you don't mind paying the shipping, I don't mind shipping it.

Connector cover set US$25

I noticed that the connectors on the unit get really dusty over time. Also, the banana line outputs and headphone TRS directly expose the interior of the unit to the elements.

These covers give me peace of mind when travelling or working in dusty, dirty locations.

(You will still need to tape up the holes at each switch when working in sandy environments.)

3- Neutrik XLR male connector cover

2- Neutrik XLR female connector cover

1- Canare BNC cover

1- 3.5mm TRS plug

These are pretty cool and very low profile. They can be easily reversed so that the cables are pointing up or down in the bag. Solder your own cables to have custom connectors and lengths.

Purchase more for different setups in your cart or bag so you can just unplug from one setup and quickly plug into another.

Comes with different radiused cable strain relief parts that you can use depending on how thick your cable is.

Returns

All components go through very strict quality control and testing by me on my own Nagra V before shipping.

I will verify general dimensions and configurations with each buyer to make sure everything is compatible with their unit. Each part will be carefully wrapped and padded for shipping.

If the machined parts do not fit your unit, then they can be returned at the buyer's expense.

All of the shipped goods will be insured so any damage can be claimed with the shipping company.

Payment

Payment will be made through Paypal in USD$. If you cannot open a Paypal account, we can find an alternate payment service.

China orders can be paid with 支付宝 or 微信.

Reasons for The Classification of Diesel Generator Sets 1

There are many classification methods for diesel generator sets, which can be divided into large, medium, and small units according to the engine speed, high and low speed, and power. According to the output voltage frequency of the generator, it can be divided into AC generator sets (intermediate frequency: 400Hz, power frequency: 50Hz) and DC generator sets. When the voltage frequency is 50Hz, the calibration voltage of small and medium-sized generators is generally 400V (three-phase) or 230V (single-phase), and the calibration voltage of large generators is generally 6.3-10.5kV. But the more commonly used classification method is based on the control mode, purpose, and appearance structure of diesel generator sets.

Classified by control method

1. Manual units are the most common type of units, which have automatic voltage and speed adjustment functions. Operators can start, close, open, and stop the units on site in the machine room. This type of unit is usually used as a main or backup power source.

2. The self starting unit is an automatic control system added to the manual unit. When there is a sudden power outage, the unit has functions such as automatic start, automatic voltage regulation, automatic frequency modulation, automatic switch on/off, and automatic shutdown; When the oil pressure of the unit is too low, the oil temperature and the cooling wood temperature are too high, it can automatically emit sound and light alarm signals. When the unit overspeeds, it can automatically stop and protect the unit. The advantage of a self starting unit is that it greatly reduces the dependence on operators and shortens the interval between mains power interruption and power supply by the unit. Such units are usually used as backup power sources.

3. The microcomputer controlled automation unit consists of a high-performance diesel engine, synchronous generator, fuel (oil, cooling water) automatic compensation device, and automatic control panel. The automatic drawing screen is controlled by a programmable logic controller (PLC), which not only has various functions of self starting the unit, but also can automatically increase or decrease the unit according to the load size, automatically handle faults, automatically record the operation report and fault situation of the printer unit, and implement comprehensive automatic control of the unit. The remote control, remote signaling, and telemetry (commonly known as "three remote") of scattered units at the central station are achieved through serial communication interfaces (RS232, RS422, or RS485), thus achieving unmanned operation. The degree of automation of the unit can be configured according to actual needs. This type of unit is particularly suitable for use as an emergency power source.

Guangxi Dingbo Power Equipment Manufacturing Co.,Ltd is an early professional manufacturer of generators and diesel generator sets in China. The company has first-class national-level large-scale production and load testing equipment. Provide users with long-term diesel generator set sales, leasing, technical consultation, commissioning, maintenance, training services and generator set trusteeship business.
