Problems solved by technology

However, in terms of system monitoring, the current communication power supply system only designs a monitoring unit. This monitoring unit is the core of system monitoring. For the power system shared by operators, users are charged according to the DC power consumption on the output side, and these important data such as DC power consumption are stored in the monitoring unit. If the monitoring unit fails or fails, it will cause corresponding losses to the user), this method It cannot meet the data security and reliability requirements of important computer rooms and applications
[0003] With the development of communication technology, telecom operators put forward higher requirements on the quality, reliability and capacity of communication power supply, especially in the case of simultaneous / same-site operation of 2G / 3G / 4G triple networks, the communication power supply The capacity requirements will become larger and larger, and its capacity requirements are generally greater than 1000 amps. It is difficult for a single cabinet to meet such a large capacity demand. Usually, a parallel multi-cabinet system is used for power supply.
Some manufacturers have designed a large-capacity communication power supply system with multiple cabinets connected in parallel. Each rectifier cabinet uses an independent monitoring unit, which requires more communication networking resources and power distribution space.
On the other hand, due to the technical barriers in improving the efficiency of the three-phase input switching rectifier module, the current development trend of large-capacity communication power supply is to use small and medium-capacity single-phase rectifier modules to build large-capacity systems, which requires the number of rectifiers to be as large as possible. Up to 100-200
In the case of a large number of rectifier modules, due to the large number of various detection and control signal lines, one monitoring unit manages dozens or even hundreds of rectifier modules, the wiring process is complicated, the production and maintenance are difficult, and there are also insufficient bus drive capabilities. There are technical problems such as poor real-time monitoring caused by too many monitoring units, and this method cannot effectively guarantee data security when a monitoring unit fails

specific Embodiment 1

[0064] Such as Figure 4 As shown, a foreign operator requires a 4800A central computer room power supply, which consists of four 1200A rectifier cabinets and an AC power distribution panel. Each rectifier cabinet is equipped with 24 50A single-phase rectifier modules and a monitoring unit. The RS485 is used as the field bus between the monitoring units to complete the mutual exchange of data between the monitoring units. Each monitoring unit communicates with the upper serial port HUB board through RS232 (the serial port HUB board is a serial port switch similar to a network switch, which realizes 1 to 4 transparent transmission), and realizes four monitoring units and the upper computer SNMP processing unit Communication transmission, SNMP processing unit has WEB SERVER function and supports SNMP protocol, responsible for the communication between the system and the background monitoring center.

specific Embodiment 2

[0068] Such as Figure 5 The example shown is an evolutionary backup monitoring networking mode. Through the parallel connection of two monitoring units and an upper switch, the slave monitoring unit immediately puts into operation after the failure of the main monitoring unit to undertake the monitoring task of the system.

specific Embodiment 3

[0069] Figure 6 In the example described in , when the intelligent rectifier module is used, and CANBUS and other communication methods are used between the monitoring unit and the rectifier module, the system architecture is further simplified. When the communication method between the monitored object and the monitored object and the background is the same as the physical link Sometimes, two monitoring units can be formed as mutual backup, which can also be used in other communication equipment systems.

[0070] This scheme mainly shows a monitoring system in which multiple monitoring units are mutually backed up. The monitoring units adopt the same hardware structure and software function program, but the main monitoring unit and the slave monitoring unit run different software modules. When the main monitoring unit In case of failure or failure, the slave monitoring unit automatically switches to the main monitoring unit, loads the backup data, and continues the various m...

Abstract

The invention discloses a direct-current power supply system and a method for implementing multi-machine monitoring. The system comprises a master monitoring unit for separately managing a rectifier cabinet and one or more slave monitoring units; the master monitoring unit is connected with each slave monitoring unit which is connected with other slave monitoring units; the master monitoring unit is used for executing a master monitoring function and managing and controlling each slave monitoring unit; and the slave monitoring unit is used for acquiring data from the master monitoring unit and the other slave monitoring units, backing up the data and being switched to the master monitoring unit when the master monitoring unit is in a non-working state and the slave monitoring unit satisfies the condition of being switched to the master monitoring unit. Through the system and the method, loss of a user due to invalidity of a high-volume communication power supply monitoring unit is avoided.
