Description

Technical Field

[0001] This utility model relates to the field of equipment testing technology, and in particular to a system for monitoring the status of smart home devices in a closed environment test chamber. Background Technology

[0002] Environmental testing is a crucial part of smart home device testing. During the testing process, smart home devices need to be powered on and placed in an environmental chamber. The temperature and humidity inside the environmental chamber must be strictly controlled according to standard requirements, and the device's working status inside the environmental chamber must be monitored at all times to simulate the device's performance under extreme environments that may be encountered during daily use. Monitoring the performance of these devices inside the environmental chamber is quite challenging.

[0003] On the one hand, because the environment chamber is a closed space and the outer shell is usually made of metal, it has a strong shielding effect against electromagnetic waves. Smart furniture mostly communicates with wireless routers and multi-mode gateways wirelessly and requires a matching app to use. Therefore, it is difficult to establish communication with these devices outside the environment chamber. If the wireless routers and multi-mode gateways that come with smart home products are put into the environment chamber for testing, it is also a concern whether these products can withstand the same high and low temperature and humidity conditions.

[0004] On the other hand, traditional methods for monitoring the environment chamber, such as using cameras, are insufficient for smart home devices that generate a lot of data during operation but do not have built-in screens for display. Visual images alone are not enough for evaluation. Furthermore, environmental tests are lengthy, and analyzing such massive amounts of video data to pinpoint the exact time when the sample malfunctioned or made a mistake during the test requires a lot of effort. In addition, this monitoring is one-way; if the working state of the sample needs to be changed, such as turning lights on or off or adjusting the gear, the environment chamber needs to be opened and operated manually, which also affects the efficiency of the test. Summary of the Invention

[0005] The purpose of this invention is to provide a system for monitoring the status of smart home devices in a closed environment test chamber.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A system for monitoring the status of smart home devices in a closed environmental test chamber is characterized by comprising an industrial control computer, an environmental chamber, and a PoE switch. The industrial control computer is equipped with a router module and a server module, both of which are virtual machines. The router module is connected to an external network and is also connected to the server module and the PoE switch. The environmental chamber is equipped with a wireless interface and a Bluetooth interface, and the PoE switch is connected to both the wireless interface and the Bluetooth interface. Several smart home devices are placed inside the environmental chamber, and these devices are directly connected to the PoE switch via the wireless interface, Bluetooth interface, or wired network. The computer control panel is also connected to the PoE switch.

[0008] Furthermore, the server module is equipped with a virtual network card, and the server module communicates with the router module through the virtual network card.

[0009] Furthermore, the Bluetooth interface includes an ESP32 microcontroller, which communicates with a PoE switch via an RJ45 interface.

[0010] Furthermore, one pin of the RJ45 interface is connected to the microcontroller via an isolation transformer and an Ethernet control chip, while the other pin of the RJ45 interface is controlled by the PoE controller of the PoE switch and is connected to the microcontroller via a full-bridge rectifier module and a flyback converter.

[0011] Furthermore, the microcontroller communicates wirelessly with the Bluetooth device inside the environmental enclosure via an onboard antenna.

[0012] This invention can monitor and control the working status of smart home devices in the environmental chamber in real time. Except for the initial configuration, which requires connection to an external network and APP, the sample can rely solely on the local network connection for monitoring and control on the web interface of this system during subsequent operation.

[0020] U1 microcontroller, U2 W5500 Ethernet control chip. Detailed Implementation

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] This utility model discloses a system for monitoring the status of smart home devices in a closed environment test chamber, such as... Figure 1 As shown, it includes an industrial control computer 1, an environment box 2, and a PoE switch 3. The industrial control computer 1 is equipped with a router module 11 and a server module 12, both of which are virtual machines.

[0023] Router module 11 is connected to the external network for communication. Router module 11 is also connected to server module 12 and PoE switch 3 for communication. Server module 12 is a Home Assistant server located on the LAN side of router module 11. Server module 12 is equipped with a virtual network card and is connected to router module 11 through the virtual network card. Server module 12 is used to monitor and control the sample being tested.

[0024] The environment box 2 is equipped with a wireless interface 21 and a Bluetooth interface 22. The PoE switch 3 is connected to the wireless interface 21 and the Bluetooth interface 22 respectively. The Bluetooth interface 22 includes an ESP32 microcontroller U1 based on the ESPHome framework, which is configured using YAML language.

[0025] like Figure 2 As shown, the microcontroller U1 communicates with the PoE switch 3 through the RJ45 interface 8. One pin of the RJ45 interface 8 is connected to the isolation transformer 5 to remove the DC component of the voltage. The DC component is then converted to the SPI protocol by the W5500 Ethernet control chip U2 and communicates with the microcontroller U1.

[0026] Another pin of the RJ45 interface 8 is separately led out and connected to the full-bridge rectifier module 6, which is controlled by the PoE controller 31 of the PoE switch 3. It negotiates the PoE voltage with the PoE switch 3 and samples and controls the output voltage of the flyback converter 7 to provide a stable 5V DC voltage for the microcontroller U1. The microcontroller U1 communicates wirelessly with the Bluetooth device located in the environmental box 2 through the onboard antenna.

[0027] In the experiment, several smart home devices were placed in the environment box 2. The smart home devices communicated with the PoE switch 3 through wireless interface 21, Bluetooth interface 22 or wired network direct connection. According to the communication method supported by the sample, the smart home device with the corresponding access method was placed in the environment box 2 and connected to the external PoE switch by network cable.

[0028] All data generated during the experiment and the control of the smart home device samples can be completed by a computer connected to the PoE switch 3. This computer is equipped with a control panel 4, or it can be directly connected to an external screen and keyboard and mouse on the industrial computer 1.

[0029] This system can connect multiple smart home device samples simultaneously and conduct tests under the same conditions in environmental chamber 2. Data generated by different smart home device samples can also be compared on the same timeline to discover subtle differences between smart home device samples, facilitating comparative tests between samples.

[0030] When a sample of an air purifier from a certain brand is connected to the system and placed in environmental chamber 2 for testing, the historical data of each sensor on the sample (such as air quality sensor, temperature and humidity sensor) and the control status of the air purifier fan are plotted as historical data charts and directly displayed on the computer control panel 4. The historical data can be compared with the temperature and humidity information in environmental chamber 2 to verify the stability and accuracy of the sample during operation. If the sample fails, the exact time of failure can also be observed through the historical data charts.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
