The wireless module can be a LoRa wireless module, and can cover all energy utilization devices through LoRa wireless and is in wireless connection with the central control system. In some embodiments, a wireless communication module such as 4G, wi F i, etc. may also be used.

Such energy usage devices include, but are not limited to, various ones such as air conditioners, lights, exhaust fans, office computers, water boilers, printers, production equipment.

Different subsystems may be built for different energy usage devices or according to functional areas.

In a certain subsystem, the monitoring sensor comprises a temperature sensor and is used for monitoring electricity consumption of the socket and the charging pile, and when the temperature monitors overtemperature (namely exceeds a threshold value), the intelligent switch automatically alarms to cut off the electricity.

In one subsystem, the monitoring sensor comprises a combined electrical fire monitor for monitoring electricity consumption and safe electricity consumption time periods in real time.

In a certain subsystem, the monitoring sensor comprises a temperature sensor, a current monitor and a voltage monitor, and is used for monitoring the electricity consumption condition and the safe electricity consumption period of the energy consumption equipment.

The intelligent monitoring module has an independent monitoring function and a combined control function. The independent monitoring function is characterized in that in a subsystem, the energy consumption condition of the energy consumption equipment can be independently monitored, and the energy consumption condition can be independently controlled in real time. The combined control function is that the energy consumption curve can be analyzed in real time in the visual display of the central control system, and the control effect of 1+N can be realized through the unified control of the central control system.

For example, for non-in-duty periods in a factory workshop (a subsystem), abnormal consumption of electric power of devices such as electric lamps, air conditioners, production machines and the like occurs; the workshop is not trimmed for many years, the circuit is aged, the carrying capacity of the circuit is poor, and the circuit is easy to trip; the system provided by the invention is used for monitoring the information of each workshop electric line in real time, collecting workshop electric data and intelligently analyzing the line loss condition by the central control system.

The electricity utilization data is displayed in real time, equipment abnormality can be timely alarmed in a central control system, and early investigation is known early.

The central control system can also set the electricity consumption period and is independently controlled by the intelligent monitoring module. Before working, the electric equipment (namely energy-consuming equipment) in the workshop is intelligently started, and after working, the electric equipment in the workshop is automatically closed.

Thereby realizing the dual benefits of electricity safety, energy saving and electricity saving.

For another example, high-power electric equipment is used for violations in dormitory (another subsystem), and the load is too high; the tripping is easy, one socket is connected with a multi-connection socket, and the circuit is easy to age, so that fire disaster is caused; the supervision has the problem of hiding, missing phenomenon etc., uses combination formula electric fire monitor through this system, and every layer dormitory is with electric wire information to and monitor dormitory power consumption condition, through threshold value setting restriction use rated power electrical apparatus. And a dormitory manager checks the service condition of each dormitory access electric appliance according to the central control system, so that the problems of inefficiency and impracticality of checking illegal electric appliances are solved.

For another example, for an irregular period in a warehouse (yet another subsystem), large-sized electrical equipment is not closed, and fire is easily caused; the electrical equipment is not closed, and energy consumption loss is generated; the circuit distribution of the large-scale electric equipment is not standard, and the problem of uneven three-phase load is easily caused; the system of the invention uses the combined electric fire monitor to monitor the parameters such as current, power, residual current and the like of each warehouse, the temperature acquisition module monitors the idle-open temperature of each warehouse, and monitors the energy consumption condition of electric equipment of the warehouse, a responsible person sets the switching time of the electric equipment through the use condition of the warehouse of the central control system, and all the electric equipment is closed by one key when the system is finished, so that the equipment is prevented from being used in an unconventional period; and monitoring the electricity consumption condition of the equipment in real time, automatically powering off the equipment abnormally and reporting to a central control system.

For another example, for an office (yet another subsystem) boiler that is not closed, a long-time boil creates a "thousand rolls of water" that is dangerous to health and causes waste of electricity; office electrical appliances such as paper shredders, sealing machines and the like have poor heat dissipation, are not powered off after being used up, are easy to generate heat, and cause fire; using a handy wall socket, idling other wall sockets, and accelerating the aging of the electric wires of the socket; the system uses a combined electric fire monitor to monitor the electricity consumption of each layer of office, monitors the state of the electric equipment of the office and limits the use of a high-power water heater with rated power through threshold setting. And the opening and closing of the equipment are controlled in a timing and intelligent manner, for example, the on-off of the time is set autonomously, the automatic control is carried out during working and working, and the fire disaster is avoided.

The intelligent monitoring module is used for carrying out one-key portable scene operation, and is matched with a central control system (central control host) to realize batch quick power-on and power-off.

And the time on-off equipment is set independently through timing control, and the automatic on-off control is performed during working and working, so that electricity is saved.

The visual display of the central control system supports the generation of electricity consumption statistical reports, supports line loss monitoring and locks the ageing position of the line.

The visual display of the central control system, which may be referred to as an intelligent electricity management platform, may be seen in fig. 1-4. FIG. 1 is a graph of visual electricity usage data analysis; FIG. 2 is a diagram of an alarm event push and device data case thereof; FIG. 3 is a chart of electricity consumption statistics day/week/month data report generation; fig. 4 is another display of a visual electricity usage data analysis curve.

In summary, the system of the invention is an electricity consumption safety and energy consumption saving management system integrating monitoring, control and maintenance, and realizes electricity consumption safety monitoring and energy consumption saving management while intelligently controlling equipment.
