[0028] Such as Figure 1 In an embodiment shown as Figure 1This is the circuit diagram of the signal acquisition circuit of a device for three - level energy consumption detection of the present utility model. The chip uses CS5460. The positive power supply 3V3 is electrically connected to pin 3 of the AD conversion chip U5 and pin 1 of the capacitor C25 respectively. The positive power supply 5V is electrically connected to pin 1 of the capacitor C15, pin 1 of the resistor R16 and pin 1 of the resistor R19 respectively.

Pin 1 of the crystal oscillator Y1 is electrically connected to pin 24 of the AD conversion chip U5. Pin 3 of the crystal oscillator Y1 is electrically connected to pin 1 of the AD conversion chip U5. Pin 1 of the capacitor C19 is electrically connected to pin 1 of the resistor R21 and pin 16 of the AD conversion chip U5 respectively. Pin 2 of the capacitor C19 is electrically connected to pin 1 of the resistor R23 and pin 15 of the AD conversion chip U5 respectively. Pin 1 of the capacitor C20 is electrically connected to pin 1 of the resistor R22 and pin 9 of the AD conversion chip U5 respectively. Pin 2 of the capacitor C20 is electrically connected to pin 1 of the resistor R24 and pin 10 of the AD conversion chip U5 respectively. The negative power supply GND is electrically connected to pin 2 of the capacitor C15, pin 2 of the capacitor C17, pin 2 of the capacitor C21, pin 2 of the capacitor C25, pin 2 of the resistor R21, pin 2 of the resistor R22, pin 2 of the resistor R23, pin 2 of the resistor R24 and pins 4 and 13 of the AD conversion chip U5 respectively. Pin 19 of the AD conversion chip U5 is electrically connected to RST. Pin 7 of the AD conversion chip U5 is electrically connected to SPI1 CSI. Pin 23 of the AD conversion chip U5 is electrically connected to SPO1 MOSI. Pin 6 of the AD conversion chip U5 is electrically connected to SPO1 MISO. Pin 5 of the AD conversion chip U5 is electrically connected to SPI1 SCK.

[0029] Among them, pin 1 of the AD conversion chip U5 is XOUT, pin 2 of the AD conversion chip U5 is CPUCLK, pin 3 of the AD conversion chip U5 is VD +, pin 4 of the AD conversion chip U5 is DGND, pin 5 of the AD conversion chip U5 is SCLK, pin 6 of the AD conversion chip U5 is SDO, pin 7 of the AD conversion chip U5 is Pin 8 of the AD conversion chip U5 is NC, pin 9 of the AD conversion chip U5 is VIN +, pin 10 of the AD conversion chip U5 is VIN -, pin 11 of the AD conversion chip U5 is VREFOUT, pin 12 of the AD conversion chip U5 is VREFIN, pin 13 of the AD conversion chip U5 is VA -, pin 14 of the AD conversion chip U5 is VA +, pin 15 of the AD conversion chip U5 is IIN -, pin 16 of the AD conversion chip U5 is IIN +, pin 17 of the AD conversion chip U5 is PFMON, pin 18 of the AD conversion chip U5 is NC, pin 19 of the AD conversion chip U5 is Pin 20 of the AD conversion chip U5 is Pin 21 of the AD conversion chip U5 is Pin 22 of the AD conversion chip U5 is Pin 23 of the AD conversion chip U5 is SDI, and pin 24 of the AD conversion chip U5 is XIN.

[0030] In one embodiment, all GND connection points are combined into a main ground wire. This includes connecting the second pins of capacitors C15, C17, C21, C25, the second pins of resistors R21, R22, R23, R24, and pins 4 and 13 of the AD conversion chip U5 to a main ground wire. Such a design can reduce the number of lines on the circuit board and improve the reliability of the circuit.

[0031] In one embodiment, since capacitors C17, C19, C20 and resistors R16, R19, R21, R22, R23, R24 are mainly used for signal protection or filtering, there may be overlapping functions in actual applications. If in the actual application scenario, the functions of some components can be achieved by other components, or if the signal line itself does not require additional protection, these redundant capacitors and resistors can be considered removed.

[0032] In one embodiment, since the RST line connected to pin 19 of the AD conversion chip U5 is only used for the reset function and there is no other complex control logic dependent on it, this line can be considered simplified or removed in actual applications. When using other chips such as chips supporting the automatic reset function, this line can be simplified or removed.

[0033] The utility model only detects the current passing through the branch through the current transformer, combines the electrical parameters transmitted in real time from the remote end, and performs the integral operation E = UIΔt to obtain the current branch energy consumption data. Since its circuit electrical parameters are remotely obtained through the serial communication circuit, there is no need to transform the high-voltage part of the circuit when installing this module, which simplifies the transformation process and reduces the hardware and labor costs.

[0034] The advantage of such a design of the utility model is that it fully considers the characteristics of system accuracy, cost-effectiveness and easy implementation, making it particularly applicable in the field of hospital energy consumption management.

[0035] First of all, accuracy is a remarkable feature of this system design. By using current transformers to detect the current passing through the branch and integrating with the electrical parameters transmitted in real time from the remote end, this design can obtain the energy consumption data of the branch very accurately. This method avoids the data errors that may occur in traditional energy consumption monitoring and provides more accurate and reliable measurement results. Accurate energy consumption data is crucial for hospitals because they can not only help to identify and solve energy waste problems but also provide solid data support for the formulation and implementation of energy-saving measures.

[0036] Secondly, this design also has significant advantages in cost-effectiveness. Traditional energy consumption monitoring systems may require large-scale renovation of existing circuits, which not only involves expensive hardware costs but also labor costs and system downtime. However, this design only detects the current passing through the branch by using current transformers, neither requiring expensive equipment nor a complex installation process. The electrical parameters transmitted in real time from the remote end are obtained remotely through the serial communication circuit. Such remote monitoring function reduces the human and material resources required for installation and maintenance, greatly reducing the overall cost.

[0037] In addition, ease of implementation is also a great benefit of this system design. Since it does not involve the renovation of the high-voltage part of the circuit, the installation of this system can be completed quickly and safely. In environments with extremely high safety requirements such as hospitals, reducing interference with the existing system is very important. This design not only simplifies the implementation process but also reduces potential safety risks, enabling the system to be put into use quickly.

[0038] Finally, this design has a high degree of flexibility and scalability. As the hospital develops and the energy consumption demand changes, the system can be expanded by adding more sensors and upgrading the software to adapt to larger-scale energy consumption monitoring needs. This flexible design ensures the long-term value of the investment and ensures that the hospital can easily adapt to new energy management challenges in the future.

[0039] In summary, the benefits of this design are to provide an accurate, cost-effective, easy-to-implement, flexible and scalable energy consumption statistics system, which can help hospitals achieve refined energy management, reduce operating costs, and support the implementation of sustainable development strategies.

[0040] As Figure 2 shown in an embodiment, Figure 2This is the system block diagram of a device for three - level energy consumption detection of the present utility model. The system designed by the present utility model is an innovative three - level energy consumption statistics scheme for hospitals. It forms an efficient and accurate energy consumption monitoring network by comprehensively utilizing a signal acquisition circuit, a power management circuit, a serial communication circuit, and a central processing unit. In the design, the power management circuit of the system not only provides necessary power support for the serial communication circuit, but also is connected to the central processing unit to ensure the smooth transmission and processing of data. In addition, the central processing unit is directly connected to the signal acquisition circuit, constituting the core part of the system operation, and processing all energy consumption data and control commands.

[0041] The signal acquisition circuit is the data source of the entire system. It consists of three key parts: an AD conversion chip, a sampling circuit, and a current transformer. The coordinated work of these parts ensures the accurate acquisition of energy consumption data. In this link, the AD conversion chip plays a crucial role. It converts the analog signals collected by the sampling circuit into digital signals so that the central processing unit can process them efficiently. The current transformer is used to monitor the current passing through the circuit and provides necessary inputs for the sampling circuit.

[0042] Such a design layout brings many benefits:

[0043] Firstly, the hierarchical design of the system ensures efficient energy consumption monitoring. By separating power management, signal acquisition, and data processing, the system can be optimized at different levels, thereby improving the overall performance. For example, the power management circuit can focus on providing stable and reliable power for the system, while the sampling circuit can focus on collecting high - quality energy consumption data.

[0044] Secondly, by adopting an AD conversion chip, the system can provide high - precision energy consumption measurement. AD conversion is the process of converting analog signals into digital signals, and this conversion is crucial for the accuracy of data and subsequent processing. Since digital signals are less susceptible to noise and interference, the measurement results of the system are more accurate, providing a solid data basis for the energy management of hospitals.

[0045] In addition, the real - time performance of the system is also an advantage that cannot be ignored. The direct connection of the central processing unit to each circuit enables data to be processed and transmitted quickly. This means that the energy consumption statistics are not only accurate but also timely. Managers can quickly obtain instant feedback on the energy consumption situation, which is crucial for timely adjusting energy use strategies and optimizing the energy consumption structure.

[0046] Moreover, the modular design of the system also brings convenience for maintenance and upgrade. The independence of each circuit and unit means that when a fault occurs or an upgrade is needed, problems can be dealt with specifically without disturbing the operation of the entire system. This not only reduces the maintenance cost but also improves the reliability of the system.

[0047] In terms of environmental protection and energy conservation, the benefits of this system are also obvious. Precise energy consumption data enables the hospital to monitor and manage energy consumption, identify problem areas of energy waste, and take corresponding energy-saving measures. In the long run, this will help the hospital reduce energy costs, promote sustainable development, and also contribute to reducing the impact on the environment.

[0048] In summary, this system for the three-level energy consumption statistics in hospitals embodies high innovation and practicality in design. It can not only provide real-time and accurate energy consumption monitoring data, but also its stable, reliable and easy-to-maintain design makes it an indispensable tool for hospital energy management. With the continuous increase in energy costs and the increasingly strict environmental protection requirements, this system will undoubtedly play an increasingly important role in modern hospital management.

[0049] In one embodiment, the utility model is used in a large comprehensive medical institution, which has multiple floors, multiple departments and various medical devices. A large number of patients come to the hospital for treatment every day, and the medical devices are almost running 24 hours a day. Such an operation mode will undoubtedly lead to a large amount of energy consumption.

[0050] After the system of the utility model is installed, the current passing through the branch is detected by a current transformer, and combined with the electrical parameters transmitted in real time from the remote end, the integral operation E = UIΔt is carried out to obtain the current energy consumption data of the branch. In this way, the hospital can understand the energy consumption of each department, each floor and even each medical device in real time. Precise energy consumption data enables the hospital to find areas or devices with high energy consumption, and thus take corresponding energy-saving measures.

[0051] For example, through energy consumption statistics, the hospital finds that the energy consumption of the lighting system on a certain floor is too high, probably because the lights are still on when there is no one. So, the hospital decides to install an intelligent lighting system on this floor, and the lights will automatically turn off when no one is detected. Another example is that the hospital finds that the energy consumption of a certain large medical device is much higher than that of similar devices. After inspection, it is found that it is caused by equipment aging. So, the hospital decides to replace this device to reduce energy consumption.

[0052] In addition, by monitoring energy consumption in real time, the hospital can also quickly discover and handle sudden energy consumption problems. For example, if the energy consumption of a certain floor suddenly rises significantly, the system will immediately send an alarm to prompt the management staff to check possible problems, such as circuit failures, equipment abnormalities, etc.

[0053] This system designed by the utility model helps to save a large amount of energy and costs. Through refined energy consumption management, the hospital can discover and solve energy consumption problems that were previously difficult to detect. At the same time, the real-time nature of the system enables the hospital to quickly respond to energy consumption problems and avoid a large amount of energy waste. In addition, the flexibility and scalability of the system allow the hospital to easily expand and upgrade the system as it develops and its energy consumption needs change. The use effect is very remarkable. The energy consumption of the hospital has decreased significantly, and the operating costs have also been greatly reduced. At the same time, the hospital has made contributions to environmental protection through energy conservation and emission reduction.

[0054] Therefore, in this embodiment, the utility model not only provides highly accurate energy consumption data to help the hospital achieve refined energy management, but also makes full use of its real-time nature, flexibility and scalability, enabling the hospital to manage energy efficiently and flexibly, effectively reducing operating costs and improving operating efficiency, providing strong support for the sustainable development of the hospital.

[0055] The utility model is not limited to the above embodiments. No matter what changes are made in its shape or material composition, as long as the structural design provided by the utility model is adopted, it is a deformation of the utility model and should be considered within the protection scope of the utility model.
