Description

Technical Field

[0001] The present invention relates to the technical field of durability testing of smart windows, and in particular to a system and method for repeatedly opening and closing a smart window for durability testing. Background Art

[0002] In the prior art, a publication number of CN118774540A and a name of a manual-automatic integrated smart silent window are disclosed. In order to ensure the yield rate of the smart window, the motor and the window sash system need to be repeatedly opened and closed for durability testing. In the past, manual testing was performed, and the window could be tested up to 200 times a day when it was in full-cycle operation. According to the national standard requirements of "Aluminum Alloy Doors and Windows" (GB / T 8478-2020) for 15,000 times of horizontal opening and 10,000 times of suspended opening, it takes nearly two months to complete the test of the above-mentioned smart windows. For smart windows of various models ready for listing, manual mobile phone testing will take more than a year, which is not only time-consuming and labor-intensive, but also has a relatively high error rate. Therefore, there is an urgent need for a fully automatic repeated opening and closing durability test system. Summary of the invention

[0003] In order to overcome the technical defects of the existing smart window manual testing, which is time-consuming and labor-intensive and has a high error rate, the present invention provides a smart window repeated opening and closing durability testing system and method.

[0004] The invention provides a smart window repeated opening and closing durability testing system, comprising a closed position sensor, a horizontally opened position sensor, a window control panel, a detection host and a PC end, wherein a window interface panel and a computer interface panel are installed on the outer side of a machine cover of the detection host, the closed position sensor and the horizontally opened position sensor are respectively arranged at corresponding positions of the window, the closed position sensor and the horizontally opened position sensor are respectively connected to an RJ11 port of the window interface panel through a 24AWG twisted pair cable, the detection host converts the signal and then outputs it through the RJ11 port of the computer interface panel, the RJ11 port of the computer interface panel is connected to an RS485 serial port of a PC end through a 24AWG twisted pair cable, the network port of the PC end is connected to an RJ45 port of the computer interface panel through a UTP network cable, the detection host converts the signal and then outputs it through the RJ45 port of the window interface panel, and the RJ45 port of the window interface panel is connected to the window control panel through the UTP network cable.

[0005] The test system of the present invention can independently control the window's horizontal opening, closing, suspended opening and pause. Compared with other window detection devices on the market, the present invention has a sophisticated design concept, does not use any mechanical connecting rod drive, and uses digital signals for all operations. It not only has low investment costs, but also has high efficiency, so that fatigue testing of windows can be completed quickly, providing strong support for the rapid entry of smart doors and windows into the market.

[0006] Preferably, the detection host includes a power supply, a first sensor receiver, a second sensor receiver and a network relay. The input end of the power supply is connected to 100V-240V AC, and the power supply outputs three 12V DC to the first sensor receiver, the second sensor receiver and the network relay respectively. The slave address of the first sensor receiver is 0x00, and the slave address of the second sensor receiver is 0x01. The RJ11 port on the window interface panel for connecting the closed position sensor and the horizontal open position sensor is respectively connected to the input end of the first sensor receiver and the second sensor receiver, and the output end of the first sensor receiver and the second sensor receiver is connected in parallel to the RJ11 port of the computer interface panel. The RJ45 port of the window interface panel and the RJ45 port of the computer interface panel are both connected to the network relay. The detection host is the connection hub between the PC and the window, and plays the role of signal translation and action command. It converts the switch signals of the closed position sensor and the horizontal open position sensor into RS485 serial port signals and sends them to the PC in the Modbus protocol format. After analysis, the PC transmits the operation of horizontal open, suspended open and closed windows to it in the Modbus protocol, which converts them into switch signals and sends them to the window control panel to command the window action. As an interface for external communication, two network panels are installed on the outside of the detection host cover, namely the window interface panel and the computer interface panel. Each panel has an RJ11 module and an RJ45 module. The RJ11 module is the interface for the closed position sensor, the horizontal open position sensor and the PC to communicate, and the RJ45 is the interface for the window to communicate with the PC.

[0007] Preferably, the first sensor receiver and the second sensor receiver both use an SP485 chip with model number STC8F2K08S2. The operating voltage of the first sensor receiver and the second sensor receiver is a DC 6 to 24 volt wide voltage. The switch quantity can be converted into an RS485 signal through a PNP or NPN wiring method, and the Modbus RTU standard protocol is used to output instructions, and finally the instructions are sent to the PC through the computer serial port. Two sensor receivers are used in the detection host, so the slave address of the Modbus protocol is also two different addresses, which are set through the 6-bit dip switch on the circuit board (64 different addresses can be set). This host sets the slave addresses 0x00 and 0x01, which correspond to the closed position sensor and the horizontal open position sensor of the window respectively.

[0008] Preferably, the closed position sensor and the horizontal open position sensor are both button self-reset switches. These two groups of button self-reset switches have two states of on and off, so the button self-reset switches can be used as switch quantity sensors.

[0009] Preferably, the network relay is a four-way PNP and NPN compatible network relay dedicated to the Internet of Things, which is in TCPSERVER working mode and communicates with the TCP Client on the PC side; the communication interface of the network relay is an RJ45 Ethernet port, which is connected to the computer interface panel via a UTP network cable, and the PC side sends the Modbus RTU command to the window control panel through the network relay, thereby realizing the four window actions of open, close, suspend and pause.

[0010] The present invention also discloses a method for testing the durability of repeated opening and closing of intelligent windows, which is implemented based on a system for testing the durability of repeated opening and closing of intelligent windows described in the present invention. First, the TCP network protocol is opened on the PC side, and the command for opening the window is sent to the detection host through the Modbus protocol. After the detection host recognizes the command, the corresponding command is sent to the window control panel, and the window control panel controls the window to perform a horizontal opening operation; after the window is horizontally opened to the set position, the horizontal opening position sensor on the window is triggered, and the horizontal opening position sensor then sends a signal that the window is horizontally opened to the detection host, and the detection host converts the signal into a Modbus command and sends it to the PC side, and the PC side issues a Modbus closing command and transmits it to the detection host, and the detection host also recognizes the command and sends it to the window control panel to close the window; after the window is closed, the closed position sensor on the window is triggered, and the closed position sensor returns the closed position signal to the PC side through the same transmission signal path, and the PC side accumulates 1 for the number of horizontal openings and stores data at the same time, which means that the window is horizontally opened. The window is successfully opened horizontally once; the PC then issues a suspended opening command, which is converted by the detection host and operated through the window control panel to perform the suspended opening action. The PC uses the time of an action cycle initially configured to make a decision. After the action cycle is completed, the PC immediately issues a window closing command, which is sent by the detection host to the window control panel to command the window to close. When the window is closed, the closed position sensor is triggered again, and the closed position sensor sends the closed position signal back to the PC through the detection host. The PC adds 1 to the suspended opening times and stores the suspended opening times data; at this time, a complete statistics of horizontal opening, closing, suspended opening, closing and horizontal opening, and suspended opening times is realized; repeat the above operations, and the detection command runs back and forth between the PC, the detection host, the closed position sensor, the horizontal opening position sensor and the window control panel until the fatigue test task times are completed; if hardware wear or other faults occur during the detection process, the detection task will always be on standby, and it can be temporarily stopped at this time, and continued after the problem is solved.

[0011] The method can count the number of times the window is horizontally opened, suspended, and horizontally opened + suspended without considering whether the window switch is in place. The window switch status is detected, and the number of window switch detections is counted only after the window is completely horizontally opened (closed). The detection process is unattended throughout, and detection can be carried out 24 hours a day, and the number of horizontal and suspended detections is counted separately. The detection process can be paused at any time. If the hardware is worn or abnormal, the test can be continued after processing. There are 6 detection methods: horizontally opened + closed, suspended opened + closed, horizontally opened + closed + suspended opened + closed, horizontally opened + closed + state detection, suspended opened + closed + state detection, horizontally opened + closed + suspended opened + closed + state detection, and horizontally opened + closed + suspended opened + closed + state detection. These 6 methods can be detected separately. The 6 detection modes in the present invention need to be configured on the PC side before detection. Using the Visual Studio platform, the detection software corresponding to the above method is written in C# language and run on the PC side. The detection software currently mainly realizes the durability test of repeated opening and closing of windows, and the data is reflected in the number of window tests. In the face of higher demands, the next step is to upgrade the detection software to add fault alarms, hardware, window fatigue analysis curves and other functions, so that the window fatigue detection system can form a large-scale, commercialized digital application system.

[0012] Compared with the prior art, the technical solution provided by the present invention has the following technical effects: through the intelligent window repeated opening and closing durability testing system and method described in the present invention, when the window is subjected to durability testing, no manual intervention is required, and more than 1,000 repeated opening and closing durability tests can be completed in a day under full automatic operation, which increases the efficiency of the original manual testing by 5 times, greatly saves manpower and detection time, and reduces the error rate to the greatest extent; the design concept of the present invention is sophisticated, and no mechanical connecting rod is used for driving, and all operations are performed using digital signals, which not only has low investment cost but also high efficiency, so that the fatigue test of the window can be completed quickly, providing strong support for the rapid entry of intelligent doors and windows into the market.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] In one embodiment, Figure 1As shown, a smart window repeated opening and closing durability test system includes a closed position sensor, a horizontal open position sensor, a window control panel, a detection host and a PC end. A window interface panel and a computer interface panel are installed on the outer side of the cover of the detection host. The closed position sensor and the horizontal open position sensor are respectively arranged at corresponding positions of the window. The closed position sensor and the horizontal open position sensor are respectively connected to the RJ11 port of the window interface panel through a 24AWG twisted pair cable. The detection host converts the signal and then outputs it through the RJ11 port of the computer interface panel. The RJ11 port of the computer interface panel is connected to the RS485 serial port of the PC end with a 24AWG twisted pair cable. The network port of the PC end is connected to the RJ45 port of the computer interface panel through a UTP network cable. The detection host converts the signal and then outputs it through the RJ45 port of the window interface panel. The RJ45 port of the window interface panel is connected to the window control panel through a UTP network cable.

[0021] The test system of the present invention can independently control the window's horizontal opening, closing, suspended opening and pause. Compared with other window detection devices on the market, the present invention has a sophisticated design concept, does not use any mechanical connecting rod drive, and uses digital signals for all operations. It not only has low investment costs, but also has high efficiency, so that fatigue testing of windows can be completed quickly, providing strong support for the rapid entry of smart doors and windows into the market.

[0022] In the specific embodiment, in order to achieve the above-mentioned purpose and effectively save costs, the present invention is completely designed and made by hand. The chassis of the detection host in the hardware is transformed from the obsolete computer host tray; the chassis data interface is formed by using a woodworking hole opener to open a hole and then using a woodworking chisel to correct it to an 86 bottom box square mouth, and the replaced telephone, network module and panel are installed; electronic components are purchased from the Internet, and the circuit is welded with an electric soldering iron according to the design, and finally the core working circuit board of the detection host is formed after being insulated and fixed with screws, hot melt adhesive, hinges, etc., forming a purely handmade hardware detection device. The closed position sensor and the horizontal open position sensor are composed of two-stage resettable long-handled button switches. Since it is required to detect whether the window is horizontally opened and closed, two-way button self-reset switches are installed as switch quantity sensors. If it is detected whether the window is suspended and opened, one more switch quantity sensor can be added. The PC end analyzes and counts the collected data through the detection software, makes different actions for different window status signals, and finally issues instructions for operating the window, and then counts the number of times the window is horizontally opened and suspended. The closed position sensor, horizontal open position sensor, detection host and PC work together, and the communication adopts TCP network and Modbus industrial control protocol.

[0023] On the basis of the above embodiments, in a preferred embodiment, the detection host includes a power supply, a first sensor receiver, a second sensor receiver and a network relay. The input end of the power supply is connected to 100V-240V AC power, and the power supply outputs three 12V DC to the first sensor receiver, the second sensor receiver and the network relay respectively. The slave address of the first sensor receiver is 0x00, and the slave address of the second sensor receiver is 0x01. The RJ11 port on the window interface panel for connecting the closed position sensor and the horizontal open position sensor is respectively connected to the input end of the first sensor receiver and the second sensor receiver, and the output end of the first sensor receiver and the second sensor receiver is connected in parallel to the RJ11 port of the computer interface panel. The RJ45 port of the window interface panel and the RJ45 port of the computer interface panel are both connected to the network relay. The detection host is the connection hub between the PC and the window, and plays the role of signal translation and action command. It converts the switch signals of the closed position sensor and the horizontal open position sensor into RS485 serial port signals and sends them to the PC in the Modbus protocol format. After analysis, the PC transmits the operation of horizontal open, suspended open and closed windows to it in the Modbus protocol, which converts them into switch signals and sends them to the window control panel to command the window action. As an interface for external communication, two network panels are installed on the outside of the detection host cover, namely the window interface panel and the computer interface panel. Each panel has an RJ11 module and an RJ45 module. The RJ11 module is the interface for the closed position sensor, the horizontal open position sensor and the PC to communicate, and the RJ45 is the interface for the window to communicate with the PC.

[0024] On the basis of the above embodiments, in a preferred embodiment, the first sensor receiver and the second sensor receiver both use SP485 chips with the model number STC8F2K08S2. The working voltage of the first sensor receiver and the second sensor receiver is a DC wide voltage of 6 to 24 volts. The switch quantity can be converted into RS485 signals through PNP or NPN wiring, and the Modbus RTU standard protocol is used to output instructions, and finally the instructions are sent to the PC through the computer serial port. Two sensor receivers are used in the detection host, so the slave address of the Modbus protocol is also two different addresses, which are set through the 6-bit dip switch on the circuit board (64 different addresses can be set). The host sets the slave addresses 0x00 and 0x01, which correspond to the closed position sensor and the horizontal open position sensor of the window respectively.

[0025] Based on the above embodiments, in a preferred embodiment, the closed position sensor and the open position sensor are both button self-reset switches. The closed position sensor is installed on the window frame on the side of the window handle when the window is closed ( Figure 2A rod is installed on the handle perpendicular to the handle. When the handle is closed, the rod will move the closed position sensor, making the closed position sensor in a closed state. When the handle is rotated to open, the vertical rod will be separated from the closed position sensor, and the closed position sensor will automatically reset, making it in a disconnected state. The same principle applies to casement windows. After setting the specific position of the window opening, another casement position sensor is installed here ( Figure 2 When the window is opened to this position, it will stop and turn the horizontal opening position sensor to make it in a closed state. When the window is closed, the window will naturally detach from the horizontal opening position sensor after leaving, and it will automatically reset and become disconnected. These two sets of button self-reset switches have two states, on and off, so the button self-reset switches can be used as switch quantity sensors.

[0026] On the basis of the above embodiments, in a preferred embodiment, the network relay is a four-way PNP and NPN compatible network relay dedicated to the Internet of Things, which is in TCP SERVER working mode and communicates with the TCP Client on the PC side; the communication interface of the network relay is an RJ45 Ethernet port, which is connected to the computer interface panel through a UTP network cable, and the PC side sends the Modbus RTU command to the window control panel through the network relay, thereby realizing the four window actions of open, close, suspended and paused.

[0027] The present invention also discloses a method for testing the durability of repeated opening and closing of intelligent windows, which is implemented based on a system for testing the durability of repeated opening and closing of intelligent windows described in the present invention. First, the TCP network protocol is opened on the PC side, and the command for opening the window is sent to the detection host through the Modbus protocol. After the detection host recognizes the command, the corresponding command is sent to the window control panel, and the window control panel controls the window to perform a horizontal opening operation; after the window is horizontally opened to the set position, the horizontal opening position sensor on the window is triggered, and the horizontal opening position sensor then sends a signal that the window is horizontally opened to the detection host, and the detection host converts the signal into a Modbus command and sends it to the PC side, and the PC side issues a Modbus closing command and transmits it to the detection host, and the detection host also recognizes the command and sends it to the window control panel to close the window; after the window is closed, the closed position sensor on the window is triggered, and the closed position sensor returns the closed position signal to the PC side through the same transmission signal path, and the PC side accumulates 1 for the number of horizontal openings and stores data at the same time, which means that the window is horizontally opened. The window is successfully opened horizontally once; the PC then issues a suspended opening command, which is converted by the detection host and operated through the window control panel to perform the suspended opening action. The PC uses the time of an action cycle initially configured to make a decision. After the action cycle is completed, the PC immediately issues a window closing command, which is sent by the detection host to the window control panel to command the window to close. When the window is closed, the closed position sensor is triggered again, and the closed position sensor sends the closed position signal back to the PC through the detection host. The PC adds 1 to the suspended opening times and stores the suspended opening times data; at this time, a complete statistics of horizontal opening, closing, suspended opening, closing and horizontal opening, and suspended opening times is realized; repeat the above operations, and the detection command runs back and forth between the PC, the detection host, the closed position sensor, the horizontal opening position sensor and the window control panel until the fatigue test task times are completed; if hardware wear or other faults occur during the detection process, the detection task will always be on standby, and it can be temporarily stopped at this time, and continued after the problem is solved.

[0028] The method can count the number of times the window is horizontally opened, suspended, and horizontally opened + suspended without considering whether the window switch is in place. The window switch status is detected, and the number of window switch detections is counted only after the window is completely horizontally opened (closed). The detection process is unattended throughout, and detection can be carried out 24 hours a day, and the number of horizontal and suspended detections is counted separately. The detection process can be paused at any time. If the hardware is worn or abnormal, the test can be continued after processing. There are 6 detection methods: horizontally opened + closed, suspended opened + closed, horizontally opened + closed + suspended opened + closed, horizontally opened + closed + state detection, suspended opened + closed + state detection, horizontally opened + closed + suspended opened + closed + state detection, and horizontally opened + closed + suspended opened + closed + state detection. These 6 methods can be detected separately. The 6 detection modes in the present invention need to be configured on the PC side before detection. Using the Visual Studio platform, the detection software corresponding to the above method is written in C# language and run on the PC side. The detection software currently mainly realizes the durability test of repeated opening and closing of windows, and the data is reflected in the number of window tests. In the face of higher demands, the next step is to upgrade the detection software to add fault alarms, hardware, window fatigue analysis curves and other functions, so that the window fatigue detection system can form a large-scale, commercialized digital application system.

[0029] The above is only a specific implementation of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
