　　1. What is a cloud database?

　　Cloud Database is a database hosted on the servers of cloud service providers (such as Amazon Web Services, Google Cloud and Microsoft Azure). Different from traditional local databases, cloud databases are completely managed and maintained by cloud service providers, and users can access and manage these databases through the Internet.

　　There are two main forms of cloud database:

　　Database as a Service (DBaaS a service): This is the most common form of cloud database. Users do not need to pay attention to the underlying hardware and database management, but only need to use the provided API or management interface for data storage, query and maintenance. Typical examples include Amazon RDS, Google Cloud SQL, Microsoft Azure SQL Database and so on.

　　Self-management cloud database: users can customize and manage the architecture and configuration of the database on the cloud platform. For example, using AWS EC2 instance to deploy MySQL, PostgreSQL and other databases provides users with greater flexibility, but requires more management work.

　　The advantages of cloud database include:

　　Flexibility and scalability: users can increase or decrease resources at any time according to their needs.

　　High availability and disaster tolerance: Cloud service providers provide automatic backup and fault recovery functions.

　　On-demand billing: users only need to pay for the resources actually used, avoiding expensive hardware investment.

　　Convenient remote access: Users can access the database anywhere through the Internet.

　　Second, how to access the cloud database?

　　Accessing a cloud database usually requires several steps. Next, we will take accessing cloud database files as an example to explain how to access cloud database from local machine or cloud server.

　　1. Create and configure a cloud database

　　Before accessing the cloud database, you need to create an instance of the cloud database first. Taking Amazon RDS as an example, the creation steps are as follows:

　　Log in to the AWS management console and enter the RDS service.

　　Click the “Create database” button and select the database type you need (such as MySQL, PostgreSQL, etc.).

　　Configure the parameters of the database instance, such as database name, user name, password, storage capacity, area, etc.

　　Configure network security groups and access rights to ensure that you can connect to the database from a local or cloud server.

　　2. Configure network connections

　　In order to access the cloud database from the local machine or cloud server, it is necessary to ensure the security and reliability of the network connection:

　　Set up security groups: In AWS, use security groups to control which IP addresses or networks can access your cloud database instance. You need to ensure that the security group configuration allows your local IP address or the IP address of the cloud server to access the database port (such as port 3306 of MySQL).

　　Configure public access rights of database instances: Some cloud database instances are configured for private network access by default, which means that they can only be accessed through VPN, private line or other instances within VPC. If you need to access from the public network, you need to enable public access or set up VPN.

　　3. Install the database client

　　Before accessing the cloud database, you need to install the corresponding database client tools:

　　MySQL client: If you are using MySQL database, you can install MySQL Workbench, DBeaver or command-line client.

　　PostgreSQL client: If you use PostgreSQL database, you can install client tools such as pgAdmin and psql.

　　SQL Server Management Studio (SSMS): If you are using Microsoft SQL Server, you can use SSMS for management.

　　4. Connect to the cloud database

　　When using the database client to connect to the cloud database, you need to provide the following information:

　　Hostname or IP address: This is the public IP address or DNS name of the cloud database.

　　Port number: the port number used by the database service (for example, the default port of MySQL is 3306).

　　User name and password: the user name and password you set when you created the database.

　　Taking MySQL as an example, the command to connect to the cloud database in MySQL client is as follows:

　　BashCopy Codemysql -h < IP address or DNS of cloud database >-u < username > -p

　　After a successful connection, you can start to perform SQL queries, manage database files and other operations.

　　5. Access to cloud database files

　　Once you successfully connect to the cloud database, you can access the files or data stored in the database. Cloud database usually does not store files directly, but stores data in tables. You can execute SQL queries to obtain data, and export the data or make a backup through the client.

　　For example, in a MySQL database, you can use the following command to export data:

　　BashCopy Codemysqldump -h < IP address of cloud database > -u < user name > -p < database name > > backup.sql

　　This command will export the entire database as a backup.sql file, which you can download locally or store in cloud storage.

　　6. Secure access to cloud database files

　　Security is an important consideration when accessing cloud database. Here are some best practices to enhance database security:

　　Encrypt the connection using SSL/TLS: Ensure that all transmitted data is encrypted to avoid data leakage.

　　Restrict access: only specific IP addresses or networks are allowed to connect to the database.

　　Back up data regularly: Make sure that the data in the cloud database is backed up to prevent data loss.

　　Enable Multi-factor Authentication (MFA): Protect the management account of the database from unauthorized access.

　　Cloud database provides flexible, efficient and extensible database services, which are suitable for applications and business needs of all sizes. By creating database instances, configuring network connections and using database client tools, you can easily access and manage data files in the cloud database. As more and more enterprises migrate their data to the cloud, it will become an important skill for developers and system administrators to know how to access the cloud database efficiently and safely.

　　First, the driving operation is not standardized: the elderly and disabled people sometimes appear in the fast lane and ignore the traffic lights when driving electric wheelchairs and old scooters. This is a very dangerous operation, because the speed of electric wheelchairs and old scooters is very slow, and the speed is generally not more than 10 kilometers per hour. Driving an electric wheelchair scooter on the fast lane will cause traffic congestion, and in the worst case, it will cause a serious traffic accident. You must not drive on the motor vehicle lane, and you should drive on the sidewalk or non-motor vehicle lane.

　　Second, electric wheelchairs and old scooters need daily maintenance, especially before use, the power and tires must be checked, and the welding points of the frame and the tightness of each screw need to be checked every once in a while. Electric scooter had better keep the battery fully charged at any time, and charge it as needed. Frequent power loss will lead to the reduction of power storage capacity. There are still many people who blindly pursue cruising range and driving speed when purchasing electric wheelchairs and old scooters. In reality, it should be chosen according to the user’s normal range of activities. If the range of activities is small, it is not necessary to choose an old scooter with too large battery capacity.

　　Third, in the process of selling electric wheelchairs and elderly scooters, many elderly people often choose portable folding electric wheelchairs for convenience. In fact, this is a serious misconception. We always guide the elderly not to move electric wheelchairs, scooters and so on. Even if it is difficult to pass, it is recommended to get off and pass. If you encounter steps on the road, it is best to ask your family or passers-by for help. It is not recommended for the elderly to move it by themselves, because the lightest folding electric wheelchair weighs about twenty or thirty kilograms. This weight is also very heavy for the elderly, and if you move it by your own strength, it may lead to unnecessary injuries such as waist fractures.

Precautions before using electric wheelchair

　　Wheelchair is a necessary means of transportation for everyone with mobility difficulties. Without it, we will be unable to move. Use wheelchairs correctly and master certain skills. It will greatly help us to take care of ourselves. Do you know what the common sense of using electric wheelchairs is? What are the precautions for using an electric wheelchair?Under people’s attention 電動輪椅價錢 Finally grow into what people need, born for the market and come for the demand. https://www.hohomedical.com/collections/light-weight-wheelchair

　　Precautions for using electric wheelchairs:

　　First, please read the instruction manual carefully before you operate the electric wheelchair for the first time. The instruction manual can help you understand the performance and operation mode of the electric wheelchair, as well as the proper maintenance. Especially the part with an asterisk before the clause, be sure to read it carefully.

　　Second, don’t use batteries with different capacities. Don’t use different brands and types of batteries. Replace all batteries together, and don’t mix old and new batteries. Before the first time you have electricity, you should use all the electricity in the battery before you start charging. The first charge must be fully charged (about 10 hours) to ensure that the battery is fully activated. Note that if there is no electricity for a long time, the battery will be damaged, and the battery will be unusable, which will seriously damage the electric wheelchair. Therefore, check whether the power supply is sufficient before use, and charge it when the power is insufficient.

　　Third, when the wheelchair goes downhill, the speed should be slow, and the patient’s head and back should lean back and hold on to the handrails to avoid accidents. Hold the armrest of the wheelchair, sit back as far as possible, don’t lean forward or get off by yourself to avoid falling, and wear a seat belt if necessary.

　　Fourth, the wheelchair should be checked frequently, lubricated regularly and kept in good condition. Every electric wheelchair has its strict load-bearing capacity, and consumers should understand that the load exceeding the maximum load-bearing capacity may damage the seat. Frame, fastener, folding mechanism, etc. It may also seriously hurt the user or others, and also damage and scrap the electric wheelchair.

　　Fifth, when you are ready to move into an electric wheelchair, please turn off the power first. Otherwise, if you touch the joystick, it may cause the electric wheelchair to move unexpectedly. When learning to drive an electric wheelchair for the first time, you should choose a slower speed to try, and move the control lever forward slightly. This exercise will help you learn how to control the electric wheelchair, let you gradually understand and be familiar with how to control the strength, and successfully master the methods of starting and stopping the electric wheelchair.

The frame materials of electric wheelchairs are varied.

　　The frame materials of electric wheelchairs are various, and each material has its own unique characteristics, which is suitable for different types of users. First of all, the mainstream frame materials are carbon steel (steel), aluminum alloy, aviation titanium alloy and carbon fiber. Carbon steel has relatively low cost and strong load-bearing capacity, but its disadvantage is that it is bulky and easy to get wet and rust. Aluminum alloy is light and relatively better in corrosion resistance, so many electric wheelchairs on the market use aluminum alloy as the frame material.As an important brand soul of the company, 電動輪椅 Has outstanding performance, through the market test, still has a strong development trend. https://www.hohomedical.com/collections/light-weight-wheelchair

　　Aviation titanium alloy is a high-end choice, with high strength and corrosion resistance, but the price is correspondingly high, which is usually used in high-end and portable electric wheelchairs.

　　Titanium alloy is a mixture of different elements such as titanium, aluminum, iron and vanadium, which has the characteristics of high strength, corrosion resistance and light weight. Carbon fiber is a composite material made of carbon fiber and resin, which has the characteristics of high stiffness, high strength and light weight. From the perspective of material composition, titanium alloy and carbon fiber have their own advantages, the strength of alloy is higher, but the density of carbon fiber is lower, so the weight is lighter. When it is necessary to reduce weight, it is more suitable to use carbon fiber, which is more durable and stronger than titanium alloy, so the electric wheelchair made of carbon fiber is close to 10 thousand yuan.

　　When choosing the frame material, we should not only consider the material itself, but also pay attention to the design and function of the frame. For example, folding electric wheelchairs bring great convenience to those who are inconvenient to bend over or have disabled hands, so that they no longer have to work hard to fold electric wheelchairs; The conventional electric wheelchair is comprehensive, affordable and stable, suitable for a wider range of users.

Advantages of Brush Motor Used in Electric Wheelchairs

　　Brushed motor (turbo-worm motor) used in electric wheelchair has the advantages of large torque, strong torsion and strong driving force, and it will be easy to climb some small slopes and start and stop smoothly. Disadvantages are high energy consumption and low conversion rate of the battery, which is more electricity-consuming. Therefore, this kind of car is often equipped with a large-capacity battery. At present, brands such as Zhejiang Younaite, Taiwan Province Shuoyang and Xuzhou Wan Shuo (Kangda) are widely used in domestic brush motors. Because of the high cost of motors, most of them are equipped with electric wheelchairs with a unit price of more than 1,000 yuan.pass 電動輪椅 It can be seen from the present situation that the market prospect is relatively broad, which is conducive to our reference and investment. https://www.hohomedical.com/collections/light-weight-wheelchair

　　Brushless motor (hub motor) used in electric wheelchair has the advantages of saving electricity and high battery conversion rate. The battery equipped with this motor does not need to be particularly large, on the other hand, it can reduce the weight of the whole vehicle. Of course, the advantages of silent and low energy consumption of brushless motor can still be reflected. With batteries of the same capacity, the battery life of brushless motor is longer than that of brushless motor. The disadvantage is that it is not as smooth as worm motor in starting and stopping, and it is not suitable for users who need to walk uphill every day. In recent years, it is more common on urban roads. There are other brands such as domestic Jindun, Uninet and Shilin. Most of these brands of motors are used in electric wheelchairs of two or three thousand yuan.

　　Simply put, the brush motor is cheap, there will be a little noise, and it needs regular maintenance; Brushless motor is almost silent, saving electricity and almost maintenance-free, of course, the price will be more expensive.

　　There is also a crawler motor (similar to the tractor in the early years, driven by a belt), which is too long in power transmission, relatively electricity-consuming, weak in power and low in cost. At present, only a few manufacturers are applying this motor.

　　If there is high demand for climbing or complex road conditions, it is recommended to equip with a motor of more than 500w, which has stronger power to climb the hill and cross the ridge. Please choose according to your own situation.
