Description

Energy/resource usage monitoring system

technical field

This application relates to energy/resource usage monitoring systems.

Background technique

The most common energy/resource usage monitoring system today is the electrical energy usage monitoring system, typically used in homes, which includes detectors and parent monitors. The detector is usually hung on the power line to detect the magnitude of the current flowing in real time (belonging to the real-time information reflecting the use of electric energy), and send it to the parent monitor, which calculates and processes it to obtain such as current power and historical power consumption data , Future electricity consumption forecast, current electricity price level (applicable to regions implementing ladder electricity prices), abnormal situation prompts and other comprehensive information on power usage status are displayed, allowing users to grasp the status of power usage.

In addition to monitoring the status of electricity consumption, the monitoring system is also suitable for monitoring the usage status of energy/resources such as gas and tap water.

The disadvantage of the existing energy/resource usage monitoring system is that the user must be next to the master monitor to know the usage status. If the master monitor is placed in the hall and the user is in the room, the user cannot know the usage status.

Contents of the invention

The purpose of this application is to allow users to easily know the energy/resource usage status even if they are in different places.

In order to achieve this goal, the inventors have envisaged using multiple master monitors to wirelessly connect the detectors in parallel, one master monitor is placed in the hall and each room, so that users can easily know the energy/resource usage in different places situation. However, each parent monitor needs to calculate and process data separately, the system hardware and operating costs are high, and the data processing results of each parent monitor may be different, which makes users at a loss.

Then provide the energy/resource usage state sub-parent monitoring system, which is characterized in that it includes a detector and a mother monitor, and the detector sends the detected real-time information of energy/resource use to the mother monitor, and the mother monitor Computing and processing to obtain comprehensive information on energy/resource usage status and then outputting it to the user, including a sub-monitor. The parent monitor wirelessly broadcasts the comprehensive information on energy/resource usage status to the sub-monitor, and the sub-monitor uses this energy /Resource usage comprehensive information is output to the user.

As long as the main monitor and the sub monitor are placed in different places, the user can know the energy/resource usage status at any one of them, which is very convenient. The calculation and processing are completed by the mother monitor, and the comprehensive information of energy/resource usage obtained by the calculation and processing is shared by the mother monitor and the sub-monitor. The sub-monitor only needs to receive and output it to the user wirelessly, which saves system hardware. and operating costs, and ensure that the comprehensive information of the energy/resource usage status output to the user by the parent monitor and the sub-monitor is consistent.

Description of drawings

Fig. 1 is a block diagram of the structure of the parent-child monitoring system of electric energy usage according to the embodiment.

Detailed ways

The parent-child monitoring system for household electric energy usage is shown in Figure 1, including a detector, a parent monitor and multiple sub-monitors. The detector is hung on the utility line between the home bus and the load. There are wireless connections between the detector and the main monitor, and between the main monitor and the sub-monitor, which allows the main monitor and the sub-monitor to be flexibly placed where needed, for example, the main monitor is placed in the hall , place a sub-monitor in each room.

The detector includes a detection circuit, a data acquisition module and a wireless transmitting device. The current of the electric circuit is detected through the detecting circuit, and the real-time information of electric energy usage is collected by the data acquisition circuit, and sent to the parent monitor by the wireless transmitting device.

The mother monitor includes a microprocessor, a wireless transceiver, a memory, a sensor module, a temperature sensor, a humidity sensor, an output module, an output device and a data transmission interface. In this embodiment, the output device has a buzzer, a display screen and an indicator light. The master monitor receives the real-time information reflecting the use of electric energy sent by the detector through the wireless transceiver device, and the microprocessor calculates and processes it to obtain such as current power, historical power consumption data, future power consumption forecast, current power price level, and abnormal conditions The comprehensive information of power usage status such as prompts is then output to the user through output devices such as buzzer, display screen and indicator light driven by the output module. The buzzer will give an alarm for abnormal conditions. At the same time, the parent monitor wirelessly broadcasts the comprehensive information of the power usage status to the child monitor through the wireless transceiver device. It can be seen that the wireless transceiver device is responsible for receiving the signal sent by the detector and broadcasting the signal to the sub-monitor, which serves two purposes. In addition, because of the sensor module, temperature sensor and humidity sensor, the mother monitor can also detect and display the ambient temperature and humidity; because of the data transmission interface, the mother monitor can also exchange data with external devices.

Each sub-monitor includes a microprocessor, a wireless receiving device, a display screen and an indicator light. The comprehensive information of the power usage status sent by the parent monitor is received through the wireless receiving device. After conversion by the microprocessor, the display screen and the indicator light will This comprehensive energy/resource usage information is output to the user. The parent-child monitoring system for power usage is taken as an example above, and designers can also make corresponding changes to be applicable to other types of parent-child monitoring systems for energy/resource usage.
