Electrical fire monitor unit with pulse metering and implementation method thereof

Abstract

The invention provides an electrical fire monitor unit with pulse metering and an implementation method thereof. The electrical fire monitor unit comprises an aftercurrent sampling unit, a temperature sampling unit, a three-phase voltage sampling unit, a three-phase current sampling unit, a four-way sampled signal filtering unit, a three-way impulse input unit, a three-way impulse output unit, a processor, a displayer, a storer, an indicator light, a push-button unit, an RS485 serial communication unit, an external clock unit and a power source unit. The electrical fire monitor unit with pulse metering and the implementation method thereof not only can conduct data acquisition on electrical fire relevant parameters but also can measure various energy parameters of a pulse metering mode, the function of the electrical fire monitor unit is enriched, the structure of the device is simplified, and therefore the multi-aspect demands of a user can be met.

Description

technical field [0001] The invention relates to the field of electrical fire monitoring, in particular to an electrical fire monitor with pulse metering and a realization method thereof. Background technique [0002] With the gradual deepening of society's understanding of electrical fire prevention, as well as the support of laws and regulations and the vigorous promotion of fire management departments, the use of electrical fire monitors is increasing. Most of the electrical fire monitors in the prior art have relatively simple functions, such as measuring the residual current of the detected electrical circuit and the cable temperature of the detected electrical circuit, resulting in a low integration level of the electrical fire monitor, making it difficult to expand its application noodle. Preferably, some electrical fire monitors can measure 1 channel of residual current and 4 channels of temperature monitoring. It also appears powerless and difficult to meet all nee...

AI Technical Summary

Problems solved by technology

[0004] The problem solved by the present invention is that in the existing electrical fire monitor, due to the single function, it cannot meet the needs of users in various aspects, or although it is compatible with the functions of electrical fire parameter collection and energy consumption information collection, the system structure is complicated and difficult to monitor. Management and maintenance, which cause inconvenience to users
