Embodiment 1

[0033] The invention provides a safe energy efficiency monitoring method and an energy efficiency monitoring terminal based on anti-tampering technology. On the one hand, the energy efficiency monitoring terminal is connected to various electrical equipment and energy consumption meters, and the energy consumption monitoring terminal reports the collected energy efficiency data, corresponding alarm information, and normal information to the management and control platform.

[0034] Among them, the security energy efficiency monitoring terminal based on anti-tampering technology is attached figure 1 As shown, it includes a CPU module 101, a reset module 201 connected to the CPU module, a key module 202, an LCD display module 203, an LED indicator light 204, a clock module 205, a data storage module 206, an interface module 207, an input and output module 208, and a measurement Chip module 209, and power module 210, it is characterized in that, described interface module compris...

Embodiment 2

[0044] The monitoring terminal described in Embodiment 1 adopts a CRC calculation and verification algorithm and a corresponding comparison and judgment mechanism. In order to ensure that key information such as CRC calculation and verification address segments are not tampered with, and to ensure that the management and control platform can correctly determine whether the energy efficiency monitoring terminal is working safely, these key information are packaged in the form of library files during design. Developers can only obtain the information through the function interface, but cannot modify these key information.

[0045] At the same time, set the verification and judgment cycle in the third step to 1 second

[0046] In terms of hardware, in order to meet the needs of existing electrical equipment and meters connected to the RS485 field communication network, this embodiment further designs multiple interfaces such as RS232, RS485, RJ45, 4-20mA / 0-10V, etc. in the hardwa...

Abstract

The invention relates to a security energy efficiency monitoring terminal based on a tamper-proof technology and a monitoring method of the security energy efficiency monitoring terminal, and belongs to the field of energy efficiency monitoring and management. According to the monitoring method, due to three steps of initialization, data acquisition and verification, the accuracy of energy efficiency data acquisition is guaranteed; the monitoring terminal performs CRC calculation, compares whether a CRC calculation result is matched with an initial verification value to judge whether data are maliciously tampered, so as to guarantee the security of energy efficiency data. By the adoption of a dynamic tamper-proof technology, CRC calculation verification is conducted regularly, and the result is submitted for system networking verification. Once a program is found to be tampered, a user calls the police immediately and ends the operation of the terminal. The security energy efficiency monitoring terminal can be effectively prevented from being illegally tampered when guaranteeing the accuracy and the instantaneity of the energy efficiency data. The shortcoming of low information security of the conventional monitoring terminal is overcome.

Description

technical field [0001] The invention relates to the field of energy efficiency monitoring and management, in particular to an energy efficiency monitoring terminal. Background technique [0002] With the rapid development of our country's economy, our country has become a big energy consumption country, and the energy utilization efficiency is lower than the international advanced level countries by more than 10 percentage points. The utilization efficiency of energy is generally very low. For this reason, the Chinese government attaches great importance to the development of energy strategies and energy conservation and emission reduction work, and proposes energy production revolution, energy consumption revolution, energy technology revolution and energy system revolution, and highly supports new energy and energy conservation and environmental protection industries. develop. Simply carrying out energy-saving transformation, equipment renewal, and new equipment cannot ac...
