What do EMS and UPS mean in express delivery?

EMS is postal express, UPS is international express, the main body of the company is different.

EMS is a courier company under China Post, the only state-owned express company at present, and a leading enterprise in the express delivery industry.

UPS (United Parcel Service) is the world's largest courier carrier and parcel delivery company, and its Shanghai international hub is located at Pudong Airport.

It's not interesting, it's just that the company is different.

What is the difference between UPS and EMS is: one is a domestic brand and the other is an American brand.

It's all couriers, two companies.

One, the company is different.

1, UPS is the United Parcel Service of the United States, which is an international express delivery. USPS is the National Postal Service, which is the postal company.

Second, the cost is different.

1. UPS is basically airborne, which is very fast, expensive and expensive. USPS is a lot slower, but it's relatively cheap.

Third, the cost is calculated differently.

1. USPS fee calculation method: for packages or documents less than 500 grams, 30 grams will be the first weight, and the additional weight will be 30 grams. For packages or documents above 500 grams, 500 grams should be the first weight, and the additional weight should be 500 grams.

2. UPS express billing method: compared with the actual weight of the package, the larger will be charged. Volumetric weight calculation formula:

Length cm x width cm x height cm 5000. The prices published on the official website of iInternet do not include remote surcharges, customs duties, return fees, handling fees and other fees.

UPS is the United Parcel Service of the United States, which is an international express company, and similar to DHL FedEx TNT, these four are the four largest international express companies in the world. And it's basically all by air, which is very fast and very expensive.

USPS is the United States Postal Service, which is a postal company, similar to China's China Post China Post. And generally USPS and China Post are members of the UPU, parcels sent from China to the United States, generally the Chinese segment is sent by China Post, and the United States segment is sent by the United States Post. Compared with UPS and other express delivery, the speed is much slower, and it often takes a month to deliver, but it is relatively cheap.

EMS is a postal express mail service.

EMS Express has a network of air and land transportation that is second to none. Relying on China Post Airlines, it has established an all-night aviation distribution network with Nanjing as the distribution center, and there are more than 20,000 special express delivery and delivery vehicles. The network system with the widest coverage provides strong support for EMS Express to achieve next-morning delivery and next-day delivery between more than 300 cities in China.

EMS Express has an efficient and well-developed mail processing in the sedan lead shirt heart. There are more than 200 processing centers in the country, including 30,000 square meters in Beijing, more than 20,000 square meters in Shanghai and 37,000 square meters in Guangzhou, and each processing center is equipped with advanced automatic sorting equipment. In 2008, the China Post Air Express Logistics Distribution Center, the largest in Asia with advanced technology and equipment, was also completed and put into use in Nanjing.

EMS Express also has leading information processing capabilities. It has established an information office platform with more than 300 cities in China as the core, which is linked to the Universal Postal Union (UPU) inquiry system to realize the global tracking and query of EMS mail. A real-time information query system has been established with the trinity of **, SMS and **.

EMS has always adhered to the core service concept of "wholeheartedly, full-speed, and global", providing fast and reliable door-to-door express delivery services for customers, and meeting the multi-level needs of customers and society to the greatest extent.

UPS is the English abbreviation of uninterruptible power supply.

UPS is an important external device that can provide continuous, stable, and uninterrupted power supply**. It is mainly used to provide stable and uninterrupted power to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc.

Classification and structure

First, the rotary motor UPS, a kind of equipment that uses generators to achieve the purpose of uninterrupted power supply, it has three kinds: AC motor with flywheel - alternator set, DC motor with battery pack - alternator set and internal combustion engine UPS system, due to the clumsy and slippery weight of the equipment is rarely used now.

2. Static transformation UPS uses a system composed of semiconductor devices, batteries, etc. to achieve uninterrupted power supply.

1. The main function of the input filter is to suppress the external interference such as astroelectric interference, industrial interference and other electromagnetic interference, surge, etc., so as to protect the safety of the internal components and circuits of UPS.

2. The rectifier and charger are devices that turn the input AC voltage into DC voltage, and the rectifier adopts a thyristor rectifier circuit like Li to achieve the purpose of voltage stabilization.

3. The battery pack plays the role of energy storage, and a sealed maintenance-free lead-acid battery is generally used. There are also oak wax using alkaline batteries, such as chromium-nickel batteries.

4. The inverter is a device that converts DC voltage into AC voltage.

5. The isolation transformer converts the AC voltage sent by the inverter into the value required by the load.

6. The transfer switch and its monitor transfer switch are converted according to the operating state of the UPS under the control of its monitor.

3. The dynamic and static combination UPS is composed of a static transformation UPS and a DC generator, and the UPS runs normally when the mains power is normal. Once the mains power is abnormal, the UPS is powered by the in-machine battery. If the mains power cannot be restored in a short time, when the battery is discharged to a certain level, the DC generator will be automatically started to charge the battery in the UPS machine, so that the discharge of the battery will be maintained uninterruptedly.

Refers to an uninterruptible power supply.

It is a device that provides backup AC power for electrical load equipment uninterrupted in the event of power grid abnormalities (such as power outage, undervoltage, interference, or surge current) to maintain the normal operation of electrical appliances.

Typically, uninterruptible power supplies are used to maintain the uninterrupted operation of critical commercial equipment or precision instruments such as computers (especially servers) or switches, preventing computer data loss, communication network disruption, or loss of control of instruments.

In North America, the large UPS used in data centers is mainly three-phase 480V, which is different from the mains three-phase 208V. The European data center uses the same three-phase 400V as the mains.
