Technical Field

[0002] As global warming has aggravated the impact on the environment and climate, the promotion of energy conservation and carbon reduction has become a global trend. In order to achieve the goal of saving energy and reducing carbon emissions, it is a common method to install energy monitoring and management systems on household appliances or factory manufacturing equipment to monitor and control the energy consumption of the machines in real time.

[0003] An energy management system is a system that saves energy by monitoring and collecting energy usage data, analyzing it, and optimizing energy usage. Such systems use various technologies and methods to track energy usage, determine the causes of energy waste, and provide optimization suggestions. Conventional energy management systems usually have meters and sensors for real-time monitoring of energy usage, such as electricity, gas, or water. These monitoring data are collected and stored in a database for further analysis and evaluation.

[0004] However, the information presented by the energy management system of the conventional technology is usually displayed in units of hours, showing the energy consumption data of the machine, such as the current hourly power consumption is 1 kilowatt (KW), and the power consumption in the past hour was 1.2 kilowatts (KW), etc. Although monitoring and analyzing the hourly energy consumption changes of the machine and properly controlling the machine can achieve the purpose of saving energy, the manufacturing machine operators on the factory production line often lack a personal experience of the energy consumption information of the hourly energy consumption simply displayed on the machine screen. Therefore, the energy consumption information provided by the energy management system makes it difficult for the manufacturing machine operators to actively cooperate in energy saving and carbon reduction. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the existing technology and propose a machine energy-saving management system.

[0049] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0050] Embodiment 1

[0051] The machine energy-saving management system created in this paper is suitable for installation on a manufacturing machine, providing real-time energy consumption and carbon emission information based on the number of processed products, thereby improving the perception of the manufacturing machine operator on the changes in energy consumption, and then guiding the operator to actively adjust the production capacity allocation and flexibly adjust the machine energy supply, so as to effectively reduce the average energy consumption and carbon emission of the machine. Figure 1, is a schematic diagram of a machine energy-saving management system of the first embodiment of the present invention. The machine energy-saving management system 100 of the first embodiment includes an energy consumption measurement module 10, a product sensing module 20, a control module 30 and a display unit 40. The energy consumption measurement module 10 and the product sensing module 20 are respectively coupled to the control module 30, and the energy usage data and product quantity of the manufacturing machine are transmitted to the control module 30. The control module 30 performs analysis operations to generate energy consumption data and carbon emission data of each product, and transmits them to the display unit 40, which displays the energy consumption and carbon emission information of each product processed by the manufacturing machine in a visual manner, so as to control the energy consumption data of each product in real time.

[0052] The energy consumption measurement module 10 is composed of an energy supply sensor installed on a manufacturing machine, which can collect the energy usage of the manufacturing machine. For example, the energy consumption measurement module 10 can measure the power usage or combustible gas usage of the manufacturing machine. In this embodiment, the energy consumption measurement module 10 is a power sensor, which is used to detect the current change state of the manufacturing machine and generate the power consumption data of the manufacturing machine. The energy consumption measurement module 10 can measure the current of the manufacturing machine over time, obtain the power consumption state at different multiple time points, and generate the historical power consumption data of the manufacturing machine corresponding to the different multiple time points. The energy consumption measurement module 10 can continuously measure the energy usage of the manufacturing machine in different time segments, including the standby mode, energy saving mode, maintenance mode and normal operation mode of the manufacturing machine, and transmit the energy usage data to the control module 30 to perform machine energy consumption analysis at different time points. In one embodiment, the energy consumption measurement module 10 may include a current sensing circuit unit. It should be noted that, for the convenience of description below, the power consumption detection data used in this embodiment is the power value.

[0053] The product sensing module 20 is composed of a sensor installed on a manufacturing machine, which can monitor the number of products processed by the manufacturing machine. The product sensing module 20 can detect each product transported to the manufacturing machine for processing to calculate the number of processed products at different time points. For example, the product sensing module 20 is a product counter with a timing function, which can calculate the number of processed products of the manufacturing machine during a period of time and generate a production data distributed over time. Taking a shoe processing machine as an example, the product sensing module 20 can count the number of sports shoes processed by the manufacturing machine every hour at different time points to generate a production history data. Furthermore, an identification barcode can be attached to each product, so that the product sensing module 20 can identify each product entering the manufacturing machine, so that when performing production statistics, the processing machine and processing time point of each product can also be recorded at the same time, and the processing data of each product can be transmitted to the control module 30 for subsequent tracking and processing.

[0054] The control module 30 is coupled to the energy consumption measurement module 10 and the product sensing module 20 respectively, and is used to generate data including energy consumption data and carbon emission data per unit of production. The control module 30 is a hardware with computing capability (e.g., a chipset), as shown in the figure, including a machine energy consumption calculation module 31, a unit production energy consumption analysis module 32, a unit production carbon emission analysis module 33, and a warning module 34.

[0055] The machine energy consumption calculation module 31 is used to calculate a plurality of energy consumption data corresponding to the manufacturing machine according to the energy usage data of the manufacturing machine provided by the energy consumption measurement module 10. For example, taking a shoe processing machine as an example, Figure 2 The graph shows the power curve changes of the machine at different time points. The peak value of the power curve in the graph is the operation time of the manufacturing machine to process the product, and the horizontal line section of the power curve in the graph is the standby time of the machine. Figure 2 As shown, within one hour, the energy consumption of the machine is 1 kilowatt per hour (1KW / hour).

[0056] The unit output energy consumption analysis module 32 is used to receive the product quantity detected by the product sensing module 20 and the energy usage data provided by the machine energy consumption calculation module 31 to analyze the energy consumption data of processed products at different time points to generate energy consumption data in units of output. Figure 3A As shown, in the current 30 minutes, a total of two pairs of shoes are processed. However, in the previous 30 minutes, the manufacturing machine was idle and there was still standby time electricity consumption. Therefore, the overall power consumption of the manufacturing machine in one hour is 1 kilowatt (1KW). The number of sports shoes processed is two pairs. After calculation, the energy consumption data based on unit output can be obtained as 500W / pair. See also Figure 3B , is the energy usage data of the manufacturing machine in another time period; as shown in the figure, the manufacturing machine is in normal operation within one hour, processing a total of six pairs of shoes. The overall power consumption within one hour is 1.5 kilowatts (1.5KW), so after calculation, the energy consumption data based on unit output can be obtained as 250W / pair.

[0057] The unit output carbon emission analysis module 33 is used to obtain a carbon emission coefficient table from the storage unit built into the control module 30, and calculate the carbon emission (carbon dioxide emission) of each product based on the unit output energy consumption data provided by the unit output energy consumption analysis module 32. Figure 2As shown, taking a shoe processing machine as an example, assuming that the power consumption of each pair of shoes is 0.5KW / pair, the energy consumption is equivalent to 0.5 kWh / pair, and the carbon emission coefficient of each kWh is 0.493kgCO2, then the carbon emission of each pair of shoes is 0.247kgCO2 / pair. Therefore, the unit output carbon emission analysis module 33 can generate carbon emission data based on unit output.

[0058] The warning module 34 compares the energy consumption data (energy consumption data per unit of output and / or carbon emission data per unit of output) generated by the above-mentioned unit output energy consumption analysis module 32 with a default reference value to determine whether it exceeds the reference value, and transmits the result to the display unit 40. The default reference value is an energy usage reference value pre-set and stored in the control module 30. For example, the unit output energy consumption of the default reference value is 300W / pair. See also Figure 3A , when the energy consumption of each pair of sports shoes produced by the manufacturing machine is 500W / pair, the warning module 34 can determine that the current unit production energy consumption is higher than the reference value according to the default reference value of unit production energy consumption (300W / pair), and generate a warning message to the display unit 40; see also Figure 3B When the energy consumption of each pair of sports shoes produced by the manufacturing machine is 250W / pair, the warning module 34 determines that the current energy consumption per unit of output is within the reference value range and meets the prescribed requirements.

[0059] The display unit 40 is coupled to the control module 30 and is used to receive and display the unit output energy consumption information from the control module 30, and a signal indicating whether the energy consumption value exceeds a default reference value (such as an indicator light of the energy consumption status). The display unit 40 is, for example, a display and includes a unit output energy consumption information display screen, see Figure 4 , is a schematic diagram of the display unit screen of the machine energy saving management system 100 of this invention. Figure 4In the figure, a shoe-making machine is taken as an example, and each unit of output is a pair of shoes. Through the calculation results of the unit output energy consumption analysis module 32, the unit output carbon emission analysis module 33 and the warning module 34 of the energy-saving management system 100 of the machine, the energy consumption information of each unit of output can be presented through the display unit 40, as shown in the figure, including the power consumption and power cost of each pair of shoes in the last hour, and the carbon dioxide emissions of each pair of shoes; at the same time, in order to provide information on changes in energy consumption, the power consumption and power cost of each pair of shoes in the previous hour, as well as the carbon dioxide emissions of each pair of shoes can be displayed. Further, the screen includes an indicator light (such as an ECO light) that changes color to display the energy consumption status. For example, when the power consumption of each pair of shoes in this hour is within the preset benchmark value range, the ECO green light is displayed on the screen; when the power consumption of each pair of shoes in this hour exceeds the default benchmark value, the ECO red light is displayed on the screen. By displaying the energy consumption information per unit of output in real time, the operator of the manufacturing machine can clearly feel the power consumption and carbon dioxide emission data of each pair of shoes produced, thereby guiding the operator to adjust the power supply mode of the manufacturing machine in a timely manner to reduce the energy consumption of the manufacturing machine.

[0060] See also Figure 5 , is a flow chart of the operation method of the machine energy-saving management system 100 of the present invention. First, in step 501, the energy consumption measurement module 10 is used to monitor the energy usage of a manufacturing machine in real time, such as the electricity usage, and the energy usage data is transmitted to the control module 30; in step 502, the product sensing module 20 is used to detect the number of products processed by the manufacturing machine in real time and transmit it to the control module; in step 503, the machine energy consumption calculation module 31 generates energy consumption data in units of time, and provides it to the unit production energy consumption analysis module 32 to calculate the energy consumption per unit product based on the energy consumption in each hour and the number of products processed; in step 504, the unit production carbon emission analysis module The block further calculates the carbon emissions per unit product based on the carbon emission coefficient; in step 505, the warning module 34 determines whether the energy consumption per unit product and the carbon emissions per unit product exceed a benchmark value; if it is determined to be yes, in step 506, the message is transmitted to the display unit 40, and the display unit 40 displays a red light signal of energy consumption, the energy consumption per unit product and the carbon emissions per unit product; if it is determined to be no, in step 507, the message is transmitted to the display unit 40, and the display unit 40 displays a green light signal of energy consumption, the energy consumption per unit product and the carbon emissions per unit product.

[0063] The machine energy saving management system 200 of the present invention may further include a storage module 60 coupled to the control module 30 for storing data generated by the energy consumption measurement module 10, the product sensing module 20 and the control module 30, as well as information input from the outside, such as default baseline values, carbon emission coefficients, date and time, etc.
