A control method for a PDU device in a data center

Abstract

The invention discloses a PDU device in a data computer room and a control method thereof. The device includes a switchboard and extension devices that communicate wirelessly with the switchboard and belong to each data computer room. Each extension device includes a single-chip microcomputer and a data acquisition system connected to the single-chip computer. Humidity sensor, overvoltage protection device, information misreporting device, wireless transmission module and local memory, the data acquisition system collects and obtains the current current, voltage, temperature and humidity data and encrypts the collected data by the single-chip microcomputer, and the single-chip microcomputer encrypts the collected data through the wireless transmission module Then send it to the switchboard, the switchboard receives and processes the collected data and stores it in the general database connected to the switchboard. The local storage is used for temporary storage of collected data when the device fails, and the switchboard is used for overall monitoring and data analysis. The invention facilitates the expansion of the PDU and is simple, and the data is transmitted after being encrypted by an encryption algorithm, thereby improving the safety and convenience of the PDU product.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a PDU device of a data machine room and a control method thereof. Background technique [0002] With the development of the network era, the data center rises in line with the trend of the times, and the PDUs in each data room also change accordingly. It has a high safety factor and saves construction costs; real-time power monitoring, automatic alarm protection; remote control is supported, which is convenient Management, flexible policy management, flexible expansion; energy metering, energy consumption evaluation and other functions. [0003] The main PDUs currently on the market are as follows: [0004] 1. PDU hardware: At present, the existing PDU is suitable for any occasion. It has multiple circuit protection functions, which can prevent overload and high temperature, lightning strikes, surges and other hazards, and maximize the safety factor of the product. The built-in...

[0005] Hardware disadvantages: PDUs on the market have no local storage function, no built-in independent communication power supply

[0007] Disadvantages of PDU software: complex data communication, each PDU communication is wired communication, complex construction process, long construction period directly lead to increased cost and complex system scalability

[0008] In this existing PDU, there is still a big disadvantage. When the communication system is powered off or the communication is interrupted, the system cannot distinguish the system communication error (for example: when the system is powered off, the software will not be able to judge whether it is a system power failure alarm or a communication interruption alarm). , the data has no place to store, the data will not be able to be queried during the power outage of the system, and the data is all wired communication, which increases the construction cost and cannot obtain accurate data

[0009] At present, the PDU and the acquisition system are wired communication, the communication methods are complex, the construction process is complex, the construction period is long, the system expansion is complicated, and the system cannot distinguish the specific alarm information when the system interrupts the alarm and the system power failure alarm. , the system will also interrupt the data transmission, and the user cannot query the data samples during the interruption
