[0002] As a key piece of equipment for simulating vehicle performance testing under extreme climate and complex environmental conditions, automotive testing environment chambers not only significantly shorten product development cycles but also effectively evaluate vehicle performance under specific environmental conditions, which is crucial for ensuring the performance and quality of automotive products. However, with increasing global emphasis on environmental protection and sustainable development, and stringent national policies requiring product carbon footprint management and equipment carbon measurement, energy consumption monitoring and energy efficiency assessment of automotive testing environment chambers have increasingly become a focus of industry attention. In practical applications, environment chambers often exhibit high energy consumption, which not only increases operating costs but also contradicts current energy conservation and emission reduction goals.

[0003] Currently, energy consumption monitoring of environmental chambers mainly relies on the overall electricity meter to count power consumption. While this method is simple and easy to implement, it cannot provide detailed information on the power consumption of individual subsystems and under specific operating conditions, resulting in a lack of targeted and effective energy management. Furthermore, because automotive testing environmental chambers are customized products, the industry lacks unified and effective energy efficiency evaluation methods and approaches. This presents numerous difficulties in assessing environmental chamber energy efficiency, conducting carbon emission measurement, and developing energy-saving measures. Summary of the Invention

[0019] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0021] The visual cloud monitoring platform provides a dynamic chart display interface and multi-dimensional data analysis functions. Specifically, it can generate and display dynamic energy consumption heatmaps to show the energy consumption intensity distribution of each subsystem over different time periods. The platform also features a multi-dimensional comparative analysis module, supporting cross-analysis of energy consumption data based on external environmental conditions, test vehicle models, and operator identities. Furthermore, it includes a customizable alarm rule engine that triggers an alert when a subsystem's energy consumption exceeds the historical average by 20%.

[0022] The visual cloud monitoring platform customizes the data display interface according to user needs, allowing users to view the required data in real time via web pages, mini-programs, and other means. User management permissions allow configuration of the data display window and modification of monitoring data settings, while ordinary users can only view the monitoring data.

[0023] In this embodiment, the subsystems of the environmental chamber to be monitored include a refrigeration system, a heating system, a humidification system, a fresh air system, a circulating air system, and a lighting and auxiliary system.

[0024] Optionally, in an embodiment, the data acquisition module includes a current sensor group and a voltage sensor group, both of which are connected to the main power supply circuit and the sub-power supply circuit of the environmental chamber to be monitored.

[0025] Both the current sensor group and the voltage sensor group are installed in the main power supply circuit and each sub-power supply circuit of the environmental chamber power distribution cabinet using a three-voltage, three-current configuration. The voltage sensor group measures all line voltages (U). 12 U 23 U 31 ) or phase voltage (U 1N U2N U 3N The current sensor group measures all three-phase line currents (I1, I2, I3).

[0026] The current sensor group includes multiple high-precision current sensors. High-precision current sensors are installed on the main power supply circuit and each sub-power supply circuit of the power distribution cabinet of the environment to be monitored to collect the current data of each power supply circuit in real time.

[0027] The voltage sensor group includes multiple high-precision voltage sensors. High-precision voltage sensors are installed on the main power supply circuit and each sub-power supply circuit of the power distribution cabinet of the environment to be monitored to collect voltage data of each power supply circuit in real time.

[0028] Specifically, the technical parameters of the high-precision current sensor and the high-precision voltage sensor meet the following requirements: current range covers 0 to 3000A, resolution is 0.1A, and accuracy is 0.5%FS; voltage range covers 0 to 500V, resolution is 0.1V, and accuracy is 0.5%FS; the sampling frequency can be configured to three levels: 1Hz, 5Hz, and 10Hz, with 1Hz sampling as the default.

[0029] The environmental chamber operates at nominal voltages of 380V and 220V, with operating currents ranging from tens to thousands of amperes. Using current sensors with a resolution of 0.1A and voltage sensors with a resolution of 0.1V avoids the waste of cost and resources caused by purchasing or customizing excessively high-precision sensors. A sampling frequency of 1Hz is sufficient to meet the requirements of data changes, while also saving system storage space and avoiding inefficient use of space.

[0030] Optionally, in an embodiment, a data storage module is further included, which is used to store the voltage and current data and energy consumption data of the main power supply circuit and the voltage and current data and energy consumption data of the sub-power supply circuit.

[0031] The data storage module uses a time-series database to store at least 30 days of energy consumption data and is configured with an automatic cleanup and backup early warning mechanism. Specifically, the data storage module adopts the following storage strategy: raw sampled data is retained for 30 days; calculated minute-level aggregated data is retained for 90 days; compressed backup files are generated daily and uploaded to private cloud storage, with a retention period of 3 years. The data storage module periodically deletes some real-time data to ensure sufficient storage space and reminds users in advance to back up necessary data.

[0032] Optionally, in an embodiment, a data transmission module is further included. The data transmission module is connected to the data acquisition module. The data transmission module is used to preprocess the voltage and current data of the main power supply circuit and the voltage and current data of the sub-power supply circuit, and transmit the preprocessed voltage and current data of the main power supply circuit and the sub-power supply circuit to the data processing module.

[0033] The data transmission module is electrically connected to the current sensor group and voltage sensor group, configured to collect raw current and voltage data, and transmit them encrypted via a 5G IoT protocol. Specifically, the data transmission module includes a data preprocessing unit and a dual-channel redundant communication unit. The data preprocessing unit is used to perform noise filtering and outlier removal on the collected current and voltage signals. The dual-channel redundant communication unit supports dual-mode transmission of 5G and Wi-Fi 6, automatically switching to Wi-Fi transmission when the 5G signal strength is below a threshold.

[0034] The data processing module receives transmitted data and calculates real-time power and cumulative energy consumption. It also synchronously acquires temperature setpoints, humidity setpoints, and execution commands of the environmental chamber's operating system. By simultaneously collecting the environmental chamber's operating status and real-time energy consumption, energy consumption analysis of different operating states of the environmental chamber can be performed intuitively and conveniently.

[0035] Optionally, in an embodiment, when the data processing module calculates the energy consumption data of the main power supply circuit and the sub-power supply circuit based on the voltage and current data of the main power supply circuit and the voltage and current data of the sub-power supply circuit, it specifically performs the following: calculating the power data of the main power supply circuit and the power data of the sub-power supply circuit based on the voltage and current data of the main power supply circuit and the voltage and current data of the sub-power supply circuit; calculating the cumulative energy consumption of the main power supply circuit and the cumulative energy consumption of the sub-power supply circuit based on the power data of the main power supply circuit and the power data of the sub-power supply circuit; and obtaining the energy consumption data of the main power supply circuit and the sub-power supply circuit based on the power data and cumulative energy consumption of the main power supply circuit and the power data and cumulative energy consumption of the sub-power supply circuit.

[0036] Based on the voltage and current data of the main power supply circuit and the sub-power supply circuit, the power data of the main power supply circuit and the sub-power supply circuit are calculated. Specifically, based on the voltage and current data of the main power supply circuit, the power of the main power supply circuit is calculated in real time using a first formula to obtain the power data of the main power supply circuit; and for each sub-power supply circuit, based on the voltage and current data of the sub-power supply circuit, the power of the sub-power supply circuit is calculated in real time using a first formula to obtain the power data of the sub-power supply circuit. The first formula is: ; Where P(t) is the power of the main power supply circuit or sub-power supply circuit in a certain second, in W; when the wiring mode is three-phase three-wire mode, U k For line voltage, when the wiring mode is three-phase four-wire mode, U k Phase voltage, V; I k The current is the three-phase line current, A; θ k Let be the phase difference between the voltage and current of each phase, expressed in rad.

[0037] Based on the power data of the main power supply circuit and the power data of the sub-power supply circuits, the cumulative energy consumption of the main power supply circuit and the cumulative energy consumption of the sub-power supply circuits are calculated. Specifically, based on the power data of the main power supply circuit, the cumulative energy consumption of the main power supply circuit is calculated using a second formula; and for each sub-power supply circuit, based on the power data of the sub-power supply circuit, the cumulative energy consumption of the sub-power supply circuit is calculated using the second formula. The second formula is: ; Where E is the cumulative energy consumption of the main power supply circuit or the sub-power supply circuit, in kWh; Δt is the sampling interval for voltage and current, set to 1s.

[0038] The data processing module is also used to control the time deviation between the environmental cabin operation system and the energy consumption monitoring system within ±0.5 seconds, and to generate JSON format data packets containing the energy consumption ratio of subsystems and the energy consumption trend of operating conditions.

[0039] Since environmental chamber systems generally cannot perform network time synchronization, synchronizing the energy consumption monitoring system time with the environmental chamber system time is beneficial for the accurate alignment of environmental chamber energy consumption data and operational status data, making energy consumption data analysis more intuitive and accurate.

[0040] Example 2 like Figure 1 As shown, this embodiment provides a method for evaluating the energy efficiency of an automotive test environment chamber, which utilizes the system described in Embodiment 1.

The time, in seconds, is the end time of the relative humidity change process in the environmental chamber to be monitored. The initial relative humidity (%) during the relative humidity change process at a certain temperature. Let be the final relative humidity during a change in relative humidity at a given temperature.

[0054] The energy consumption for constant temperature operation is calculated using the following mathematical model: ; in, The average power, kW, is the power required to maintain a specific temperature in the environmental chamber.
