Mobile base surveillance system overview

This system is designed for mobile base station power equipment running status of remote monitoring, real-time monitoring of hydraulic generator and fuel quantity, grid, etc.Accurate electricity equipment operation by base stationDTUSent to the monitoring platform or on the phone.Thus effectively ensure the safe and stable operation of mobile base station.

Mobile base monitoring system is introduced:

With the rapid development of mobile communication enterprise in our country, scale continuous development and expansion of the mobile communication network.Set up numerous sizes and distribution of a wide range of base station.Need the amplitude of the generator operation and maintenance equipment and maintenance.In the face of such situation.Take turns to patrol traditional way for dispersed maintenance and artificial monitoring management.Not only waste of manpower and material resources.And poor reliability, real-time performance is not high, this way already can not adapt to the rapid development of communication business needs.In order to ensure that communication system's normal operation.Maintenance of generator equipment and generator system put forward new and higher requirements.The characteristics of this kind of requirement is:Implementation of generator set, communication equipment, electric power environment for remote monitoring function, termination of an unmanned guarding.The result will avoid the lack of scientific management and human negligence may cause burning machine, crashes, power outages, combustion led to the suspension of communication such as major accident, greatly improve the quality of equipment maintenance management, to reduce the maintenance cost of the system and guarantee system operation is in good working condition at the same time, thus greatly enhance the overall efficiency.

In communication network in China, the most number of base stations, wide coverage, there are a lot of mountain base station, maintenance is difficult, while the power interruption of mobile communication form day performance is more obvious.Based on the analysis, all base station fault back clothing found caused by power failure rates as high as20-30%.Base station blackout, due to not timely or notices or not in time nobody tracking, etc.Often cause base station suit back.Base station back clothing influence network quality not only, still use inconvenience to users, and seriously shape the image of the company.How to ensure that under the blackouts, network quality is not affected, which is to maintain an important work.A base station power generation is the main solution:Base station blackout, the DaiWei company organizational power.

Is the core of a base station monitoring system Multi-functional base station monitor, the device is based on PC hardware structure, is a collection data, remote control, remote regulating, data communication software platform.

6, suitable for three phase four wire, three-phase three-wire, single phase 2 lines, two phase three lines (v) 120/240 50/60 hz power supply system;

7, the acquisition and display/electric power three-phase voltage, three-phase current, phase sequence, frequency, active power, reactive power, power factor, electric power, the engine of all kinds of sensor data;

8, mains with over voltage, under voltage, frequency, frequency, phase and reverse phase sequence warning function, power frequency overvoltage, undervoltage, over, under frequency, over current, over power, reverse power, lack of phase, reverse phase sequence warning and stop protection function;

9, three fixed analog quantity sensors (temperature, pressure, liquid level), a variety of temperature and pressure sensor, oil bits curve can use directly, and can be custom sensor curve;

10, two programmable analog quantity sensors can be set to the temperature or pressure or liquid level sensor (LXC72X0 only have this function);

11, control, protection function: to realize automatic diesel and gas generator starting/stopping, close/brake switch (ATS) and perfect function for the protection of fault display, when multiple warning, warning column will display them in turn, facilitate analysis reason;

12, all outlet for relay output, the output and mainly adopts 16 a relay output, at the same time there are three passive relay output, more convenient for the application of complex;

13, parameter setting function: allows the user to change the parameters setting, within the memory block in the internal EEPROM memory at the same time, also is not lost in when the system is powered off.Almost all the parameters can be adjusted from the controller front panel, all the parameters can be used to PC through USB interface, and can be adjusted using PC via RS485 interface;

14, has advanced iot function, through GPRS mobile network and Internet connectivity, in any place can remote monitoring network;

15, a variety of start-up success conditions (speed sensor, oil pressure, power generation, charger) can choose, suitable for all special occasions demand;

16, wide range of power supply (8 ~ 35) VDC, can adapt to different environment, starter battery voltage can continue under starting motor instantaneous ultra low voltage

Work for 3 seconds.

Historical fault record 200 article, can record the moment in a warning or fault occurring oil pressure, water temperature, voltage, current, power and other important parameters, easy to analysis the reason and repair;

17, real-time clock, timer switch machine (weekly/monthly/boot up once a day and can be installed whether or not to bring a load) function;

18, can be used in pump unit, also can be used as indicating instrument used (only indication, alarm, relay no action);
