Operation record controller for black box of electrical equipment

Abstract

The invention discloses an operation record controller for a black box of electrical equipment, and the controller comprises a structure and a circuit. The structure comprises a recorder case, a circuit board in the recorder case, and an input / output interface of a circuit board module. The controller has the following advantages that 1, the controller supports the serial port and network communication, and is suitable for various types of working environments; 2, the controller supports a micro SD storage card with the capacity of 128G or greater, and the SD card can achieve hot swapping, i.e., plug and use; 3, the controller employs two SD cards to storage data, and automatically synchronizes the data of the SD cards; 4, input, output and communication are completely isolated and connected, thereby effectively protecting the safety of the equipment; 5, digital signal and analog signal ground lines are separated, thereby preventing a digital value and an analog value to interfere with each other; 6, a low-pass filter is employed for analog collection input, thereby improving the performance of interference resistance, and improving the collection precision; 7, the controller can be flexibly switched between an automatic control mode and a manual control mode; 8, the controller can set automatic inspection and automatic alarm.

Description

Technical field [0001] The invention relates to a black box operation record controller for electric equipment. The invention discloses a black box operation record controller for electric equipment. The operation record data has strict anti-tampering and anti-deletion functions, and is called a black box for electric equipment operation control and recording. Background technique [0002] With the rapid development of science and technology and the rapid development of the sensor industry, in the field of electrical control, such as the addition of pressure sensors to the control cabinets of domestic water pumps and fire water pumps, the birth of electronic pressure controllers has quickly gained market recognition with its unique advantages . The sensor probe is added to the control system to sense pressure, and the single-chip technology is used in the control circuit to realize multiple intelligent control functions. A control device for various pumps, motors, fans, fire pum...

AI Technical Summary

Problems solved by technology

The start and stop of the fire pump is generally realized by multiple intermediate relays and time relays in the secondary circuit in the traditional fire pump control cabinet. This control method has disadvantages such as a large number of components, complicated wiring, and poor versatility. And upgrades have brought great difficulties, and there is no running record function, and there is no black box running record, and there is no strict anti-tampering and anti-deletion function of running record data

[0004] With the improvement of fire control system requirements for fire pump control, some control cabinet manufacturers in the market have developed control cabinets with dual power switching functions, fire pump automatic inspection functions and remote control functions according to customer needs. The cabinet greatly improves the reliability and automation of the fire pump control system, but these newly added functional modules are independent of the control of the fire pump, and are just a simple integration of the functions of the two systems, and many control cabinets are all functional modules Provided by different manufacturers, it is very difficult to maintain and upgrade these systems, and the cost is relatively high
