Industry what are the advantages of 4G LTE modem for use in the power
industry
Personal safety tens of millions, electricity safety first, high-voltage
electricity is known as the "toothless" tiger, has been emphasized safe power
supply, safe electricity.However, with the rapid development of social industry,
the demand for the power industry is becoming more and more stringent. As a huge
and complex system, the overall operation of the power system is becoming
increasingly complex with the development, which puts forward higher
requirements for power system scheduling and wireless data transmission.As a
dispatcher, the workload is undoubtedly dangerous and complicated for the staff
to understand the power situation in real time and control the power grid
information, such as current and voltage, industrial and civil electricity and
the sudden security situation of the power grid.
As one of the lifelines of the national economy, the electric power
industry must guard this barrier, take the safe power supply as the premise,
improve the automation level of the dispatching system instead of manual
operation, and implement the concept of "safe power supply, safe power
consumption".Based on this demand, the advantages of Industry 4G LTE modem are
obvious. As a data transmission device, PUSR Industry 4G LTE modem can provide
an efficient and reasonable solution for power data transmission.
Industry 4G LTE modem enabling power supply system
Industry 4G LTE modem can effectively improve the automation level of
dispatching system in power system in the application of power industry.Special
induction equipment can be installed at the key nodes of the power grid, and the
real-time data information of the power grid can be transmitted to the remote
control room through the Industry 4G LTE modem, so that the dispatcher can
easily monitor the situation of the grid, more effectively optimize the
allocation of power resources, greatly improve the economic benefits of grid
operation, and reduce the labor intensity of personnel.
System principle
In the power dispatching system, the functions of Industry 4G LTE modem can
be flexibly combined through software configuration. The 4G LTE modem function module
transmits data information such as high-voltage line voltage, line current, zero
sequence current and equipment status in real time and uploads them to the
cloud. The functions of line fault detection and removal can be effectively
realized through data analysis.The communication management module is provided
with various communication interfaces and various standard communication
protocols. In addition to the internal data management function of the terminal,
it can also forward the data of the electric energy meter, PLC and DC screen in
the distribution room or switching station, and complete the data transmission
with the master station system through a standard unified interface.
The only standard for 4G LTE modem
In the future, more efforts should be made to popularize the intelligent
power supply system, which is in line with the development concept of social
development, stable and mature power supply in rural and urban areas. It is this
development trend that has given birth to the evolution of PUSR Industry 4G LTE
modem. The growing market prospects require a clear division of the track, and
PUSR Industry 4G LTE modem caters to the development trend of the power
industry.
1. And that real-time performance of the data is strong
Industry 4G LTE modem has the function of network heartbeat packet, which
can be online for 24 hours without system delay, and synchronously receive and
process all the collected data. It can meet the real-time requirement of the
scheduling system.
2. Wide applicable monitoring range
The 4G LTE modem can be deployed and used in any area covered by the
operator's communication network, which can meet the access needs of different
areas such as mountainous areas and towns.
3. Hort construction period, low cost and simple use.
The 4G LTE modem can provide efficient and reliable communication transmission for
the power system through the communication network of the operator, and can
provide wide-area wireless IP connection by using the existing network system of
the operator, so that the construction period is shortened, the construction
cost is reduced, and the equipment is simple to use.
4. High data transfer rate
The maximum downlink rate of data transmission of the Industry 4G LTE modem
is 10Mbps, and the maximum uplink rate is 5Mbps, which can fully meet the
transmission needs.
5. And that anti-interference capability is strong
Industry 4G LTE modem can meet the application environment of high power
interference in the power industry.
PUSR Industry 4G LTE modem has been closely following the development needs
of the market, in order to ensure that every function, software and hardware are
updated and iterated with the development of the industry. With the strength of
the industry, we hope to popularize the intelligent power system in an all-round
way, push it to remote mountainous areas and light up thousands of lights. Call
for every participation to become the self-circulation vitality of the
development of the power industry.
