Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1 to 23, the present invention provides a technical solution:

A window sash electric control system is shown in fig. 1, and a system structure block diagram shows a plurality of electric equipment linkage modes. The linkage equipment listed in the system comprises an electric curtain window part, an electric window opener, a casement electric handle, an indoor air purifier, a fresh air system, an indoor exhaust system, an air quality detector (indoor), an air quality detector (outdoor), a wind sensor, a light sensor and a rain sensor; the control equipment comprises a mobile phone APP, a radio frequency remote controller 1 and a radio frequency remote controller 2; the network communication and linkage consists of a server, a home router and an intelligent gateway.

The user can control the electrical equipment in the system through the mobile phone APP and the radio frequency remote controller. Air and environmental parameters can be set in the App, and the system can intelligently and automatically adjust the linkage working scheme of the electrical equipment according to the connected equipment. APP will send the linkage scheme to intelligent gateway through the network, and intelligent gateway stores the linkage control work immediately after the scheme.

The system has the advantages that the system can be separated from the Internet to carry out linkage control work during special use, and the use is more convenient. Compared with the traditional mode, the window control device has the advantages that the window electric handle is additionally arranged, the window can be controlled more reasonably, the window opening mode can be switched to the system window, the window can be locked by using the original hardware on the window, structural modification is not needed for the window, and the window is safer.

The intelligent gateway is provided with an independent control system, and the system can also carry out linkage control in a non-networking state. The electric window opener and the electric window sash handle are simultaneously installed on the window to perform combined work, so that the control of the window is more reasonable.

The system is based on the switch control work of the electric window opener to the window sashes. Compared with the prior art, the intelligent indoor environment control system is single, can only realize linkage work with simple function, has more defects of key equipment in the system, namely a window opener, and can realize or approach to the required indoor environment without manual intervention. Meanwhile, aiming at the defects of the existing window opener technology, a better structural control scheme for the window is provided.

The system is a control system based on a window opener, and covers part of electrical equipment which can work in linkage with the window opener. The system is suitable for the adjustment of various indoor environments and provides convenience for living generation.

Specifically, the linkage of the window sash transmission hardware and the electric window opener is realized through the electric handle, and the electric transformation process of the traditional window sash is greatly simplified. The control system combines various external electrical equipment surrounding the electric window, can support various linkage working schemes, and can provide convenience for life.

Among the above components, except for the electric window opener and the electric window fan handle, the electric window opening and closing device can be based on the prior art, for example, the electric window curtain part is an automatically unfolded and folded window curtain of an electric opening and closing curtain series, an electric lifting curtain series and the like which are formed by components such as a motor, a controller, pulleys, a belt and the like. The other components of the system are further described below:

1. Gateway function: in the whole intelligent home system formed by a plurality of devices, the gateway functions very similar to a wireless router and is responsible for communication work between different network segments and protocols, similar to what people say as a translation officer. The router is a networking device which constructs the bottom layer support of the wireless WiFi hot spot local area network in the whole home and is arranged between an intranet (local area network) and an extranet (Internet) or an upper-level network segment, and the gateway belongs to data transfer devices among different transmission protocols in the intranet. Several wireless connection modes are common in intelligent households, such as WIFI, bluetooth, zigbee and radio frequency 315/433.

(1): The radio frequency 315/433 is the earliest and most common scheme used in the field of smart home, has simple design and low cost, but has the fatal weakness that bidirectional real-time feedback communication cannot be performed, that is, the state of the controlled equipment cannot be reflected in real time after a control signal is sent out, and is supposed to be eliminated. (2): wiFi is characterized by more devices, wide range and high speed, but has large power consumption and is not suitable for being used as a low-power consumption sensor. Bluetooth is characterized by low power consumption, good stability, and open protocol, but multiple networks are cumbersome and are usually one-to-one. (3): the ZigBee technology is a two-way wireless communication technology with short distance, low complexity, low power consumption, low speed and low cost, zigBee can work at 2.4GH (global), the highest of 250Kbit/s and the lowest of 20Kbit/s, the transmission distance is between 10M and 75M, the safety of ZigBee is well recognized, and an AES-128 encryption mode is adopted, and in addition, the self-organizing network and the self-healing capacity of a ZigBee network are strong.

2. What is Bluetooth Low Energy (BLE) and bluetooth gateway? Bluetooth low energy (Bluetooth Low Energy, bluetooth LE, BLE) is also called Bluetooth low energy, which is a personal wireless local area network technology, and is lower in power consumption and longer in transmission distance compared with classical Bluetooth used on devices such as mobile phones, headphones, televisions, PCs or sound equipment, and is mainly applied to some intelligent home devices powered by batteries. Because of power consumption, cost, security and other considerations, the BLE sub-device itself is not generally integrated with the WiFi module, and therefore cannot be directly and independently connected to the router and the external network, and can be realized only by means of the bluetooth gateway device.

3. What is the Zigbee transport protocol and Zigbee gateway? ZigBee is also called as Zigbee, and is a wireless network protocol for low-speed short-distance transmission, and is mainly characterized by low speed, low power consumption, low cost and support of a large number of network nodes and various topological structures.

4. Why do not go directly through the WiFi connection router, but need to be relayed by means of a gateway? It is theoretically certainly possible if all devices are directly connected to the router in WiFi mode, without using a gateway for data transfer. However, for the whole intelligent home system network, if only a few devices participate, there are no problems, but with the increasing of various new devices, a plurality of obvious problems are necessarily brought: first, if the entire network has only one router hub, such a huge number of device bases may not be supported, and moreover, although WiFi transmission capability is stronger, dead corners and dead zones may exist for residences with a slightly larger area and multiple rooms. Even if the number of router access devices is not limited, and dead-angle-free WiFi perfect coverage is realized in a whole house, too many device accesses and transmissions are likely to cause congestion and interference, so that the operation efficiency and the actual experience of the whole network are affected; the power consumption of the WiFi transmission equipment to the electric energy is increased, so that more equipment cannot work independently from the constraint of the power line, and even if a battery with larger capacity is adopted, the battery needs to be replaced or charged frequently, and the equipment is greatly limited and influenced in size, development difficulty, maintenance cost, flexibility, convenience and the like; if all transmission processes are completed by WiFi, a router and an external network, only a unique data exchange center exists in the network, and all control and scenes can not be realized once the network has problems, the method means that the linkage of all equipment such as a switch, a security defense arrangement and the like which rely on WiFi transmission is similar to that of the dummy equipment; for intelligent equipment with higher safety requirements such as fingerprint locks, if the intelligent equipment is directly connected to an intranet and an extranet through WiFi, even if a more advanced encryption transmission protocol and a more advanced encryption transmission process are adopted, the risk of illegal monitoring, tampering and control of the intelligent equipment is higher; more importantly, if all devices are implanted with the WiFi transmission chip, the research and development cost and the hardware cost are gradually increased, and meanwhile, the deployment budget and the threshold of the smart home are also increased. And the instruction transmission message between some devices and the router is usually only a few KB, which is wasteful for the communication capability of WiFi. In summary, only the gateway and the multi-protocol transfer are adopted to realize the data transmission exchange of the devices, which is the most efficient and feasible solution in the intelligent home system at present and in the long future. Along with the gradual popularization of Zigbee 3.0 and Bluetooth gateway technologies, it is believed that the multimode gateway will become an indispensable important hardware component in future intelligent home system deployment and upgrading, and can embody and exert more excellent core value and practical effect.

5. Communication chip model built-in of common intelligent home products: according to different functions of the product, the requirement of the product on network communication is different. Products with low power consumption, large quantity and small data volume are commonly used as radio frequency, bluetooth and zigbee modules. Products with large data transmission quantity are commonly used for data transmission by a WiFi module. Electric curtain: the electric curtain needs to meet the outdoor remote networking control and indoor short-range remote control of a user, and when in remote networking control, the electric curtain generally contains a large amount of data information such as opening size, timing switch and the like, so that 2 modules of WiFi and radio frequency are simultaneously arranged in a general product. The WiFi module is typically ESP8266 and the radio frequency module is typically a CC1101 radio module (433 MHz). Electric window opener: the electric window opener needs to meet the outdoor remote networking control and indoor short-range remote control of a user, and when in remote networking control, the electric window opener generally comprises a large amount of data information such as window opening size, timing window opening and closing and the like, so that 2 modules of WiFi and radio frequency are simultaneously arranged in a general product. The WiFi module is typically ESP8266 and the radio frequency module is typically a CC1101 radio module (433 MHz). Electric handle of window sash: the electric handle of the window sash is required to meet the outdoor remote networking control and indoor short-range remote control of a user, and when in remote networking control, the electric handle generally comprises a large amount of data information such as window sash modes (inwards inverted, inwards opened and locked), timing window opening and closing and the like, so that 2 modules of WiFi and radio frequency are simultaneously arranged in a general product. The WiFi module is typically ESP8266 and the radio frequency module is typically a CC1101 radio module (433 MHz). An air treatment device: when the air treatment device generally needs to meet the requirement of remote networking control of outdoor remote networking control of a user, the air treatment device generally comprises a large amount of data information such as a working air volume gear, a timing switch air treatment function, uploading air quality data and the like, and the product is generally provided with a control panel, so the product is generally only provided with a WiFi module. The WiFi module is typically ESP8266. Air detection device: adopt for example, an air quality detector (CN 201920582419.0), this product is a novel air detection device, and its inside has the wiFi module, can be in real time with data such as detected air quality send the user through the network, also can transmit data to intelligent house control system, and intelligent house control system can be according to these data control intelligent house equipment work to realize the environment and improve automatically. The WiFi module is typically ESP8266. Wind-light-rain detection device: the wind, light and rain detection device usually sends out simple data, and the product works outdoors, so that external power supply is not adopted, and the internal battery is usually used for power supply. The positioning of the product with low power consumption determines the communication mode, so the product is usually provided with only a Bluetooth module. The bluetooth module is typically NRF51802.

6. Multifunctional gateway chip scheme: zigBee: the multifunctional gateway adopts an industrial ZigBee radio frequency chip (JN 5168) based on NXP to carry out networking communication; wiFi: ESP-12F; bluetooth: HC-05; radio frequency: CC1101 (433 MHz).

In the present system, the electric window opener is a device for controlling the opening and closing of the window sash. When the electric window opener is used for inwards opening and inwards reversing windows, inwards reversing, inwards opening and locking states of window sashes can be realized. When the device is used for a casement window, the casement and locking states of the window sashes can be realized.

As shown in fig. 2-3, the upper cover plate 1 and the housing 2 are assembled by a screw A5; the front panel 3 and the housing 2 are assembled by screws C7; the screw B6 is used for fixing the electric window opener main body to the window frame 22; an electromagnetic clutch 8, a motor 9, a gear set 10 and a circuit board 12 are arranged in the shell 2; the motor 9 is used for providing power for pushing the window sash (window sash frame 22); the gear set 10 is used for converting the power provided by the motor 9, reducing the rotating speed and improving the torsion; the electromagnetic clutch 8 is used for rigid and flexible connection of the gear set 10 and the link a 11. When the electromagnetic clutch 8 is electrified, the gear set 10 is rigidly connected with the connecting rod A11, the motor 9 drives the connecting rod A11 through the gear set 10 to drive the window sash to move, and manual window sash opening and closing are not allowed. When the electromagnetic clutch 8 is powered off, the gear set 10 and the connecting rod A11 are flexibly connected, and weak damping force exists between the gear set 10 and the connecting rod A11, and the damping force is used for preventing the window sash from swinging under the wind force, and the window sash is allowed to be manually opened and closed. When the electric window opener receives a window opening signal, the electromagnetic clutch 8 is electrified, and when the window opening action is completed, the electromagnetic clutch 8 is powered off; the screw D16 is used to fix 17 the rail to the window frame 41; a slide block 18 is arranged on the guide rail 17, and the slide block 18 can slide on the guide rail 17; the link a11 is connected to the link B15, and the other end of the link B15 is connected to the steering link 19 via the cross 20. As shown in the "open/tilt-in/lock mode status of the window opener" of fig. 4-12, the multi-section link multi-axis structure achieves perfect adaptation of tilt-in window.

As shown in fig. 2, the circuit board 12 is provided with a WiFi module (ESP 8266) 13 and a radio frequency module (433 MHz) 14, the WiFi module 13 is used for networking control of the electric window opener, and the WiFi module 13 can be directly connected with a router or an intelligent gateway, so that higher-level linkage control is realized. The rf module 14 is used for short-range remote control of the electric window opener, and the remote control device of the electric window opener may be an 86 panel type rf remote control or a mobile hand-held remote control, i.e. the rf remote control ii of fig. 1.

When the electric window opener is opened or closed by remote control of the mobile phone APP or the radio frequency remote controller II, when the connecting rod B15 stretches or contracts in place, the current of the motor 9 becomes large, and the circuit board is used for detecting the current, so that the power failure of the motor 9 is controlled to stop.

The electric window opener is in an open/inward reverse/locking mode in the window opener, the movement state of the electric window opener is shown in fig. 10-12, the left side is a vertical view, and the right side is a view from the position A in the vertical view. Compared with the existing electric window openers, the electric window openers are mainly chain type window openers, and the window openers are self-locking. After the traditional window is provided with the electric window opener, a user can not control the window sash to be opened or closed in a manual mode, the window sash is completely controlled by the electric window opener, and the original handle, the transmission box and the window lock can be disabled. The self-locking characteristic of the window opener replaces a hardware structure lock of a window sash, the window sash cannot be locked through the original hardware, and the safety of the window sash can be greatly reduced. The function of the conventional electric window opener is limited, and the window can be simply opened or closed. When the window opener is installed on a multifunctional system window (such as upper suspension, inward tilting and flat-open), the window handle cannot be controlled, so that the window opener cannot realize all functions of the system window. The electric window opener has a networking function, and a user can remotely control the window to be opened and closed. And simultaneously, the window can be controlled to be opened and closed conveniently. (the user can control the window remotely through the network control, or like traditional window manual open and shut.) the control window is better scientific and reasonable. (the original structure of the window is not damaged during installation, and the original functions and structures of a user are not affected during use.) so that the problem of single window sash opening mode of the traditional electric window opener is solved. And the problem that a user cannot manually open and close the window sash when the power failure or mechanical failure occurs in the traditional electric window opener is solved. The electric window opener is of a multi-connecting rod structure and is compatible with two modes of inward opening and inward pouring of a window sash. The use of the device does not affect the functions of hardware on a window. When a power failure or a mechanical failure of the window opener occurs, a user can manually open and close the window, and the structural safety of the window cannot be affected.

In the system, as shown in fig. 13 and 14, the window sash electric handle is similar to a fingerprint door lock in shape. The handle 24 is shown to be functionally consistent with a conventional handle for switching sash modes; the square shaft 30 is a power output shaft and is used for driving the hardware transmission box in the window frame 41 to work. The specification of the square shaft 30 is a general specification (the cross section size is 7 mm) of the main stream in the market and is consistent with the output shaft of the traditional handle, so that a hardware transmission box in the window frame 41 does not need special customization, and the use cost of the electric handle of the window sash is reduced; the mode deflector rod 25 is used for switching the manual mode and the electric mode of the electric handle of the window sash, and when the electric window opener or the electric handle of the window sash fails, a user can dial the mode deflector rod 25 to actuate the manual mode to temporarily and manually open and close the window; the panel 28 is provided with a key 26 for switching the opening and closing modes of the window sash (inwardly opened and closed window; casement and closed window).

The visible part of the handle 24, the mode deflector 25 and the square shaft 30 are movable parts, the square shaft 3 rotates in the same direction along with the rotation of the handle 24, the states of the handle 24 which can appear along with different windows are also different, as shown in fig. 23, which is a schematic diagram of the angle position of the handle, and is schematically shown as 3 states of the electric handle of the window sash which is arranged on the inwardly opened and inwardly inverted window. When the window is opened horizontally, the window is not in an inward-falling state.

As shown in fig. 15, the panel 28 is assembled with the housing 29 by means of snap, glue and magnetic attraction; the handle 24 and the driving wheel 40 are assembled through the countersunk head screw B34, and the driving wheel 40 is provided with a hexagonal protrusion which can be inserted into the inner hexagonal groove of the handle 24. Meanwhile, the other side of the driving wheel 40 is provided with a square groove, and the square shaft 30 can be inserted into the square groove of the driving wheel 40. The handle 24, the driving wheel 40, the countersunk head screw B34 and the square shaft 30 are relatively fixed. Thus, when the user turns the handle 24, the driving wheel 40, the countersunk head screw B34 and the square shaft 30 are turned synchronously. When the driving wheel 40 is used as a driving wheel in the electric mode, the handle 24, the countersunk head screw B34 and the square shaft 30 are rotated synchronously when the driving wheel 40 rotates.

As shown in fig. 16, the mode shifter lever 25 has a D-shaped groove, one end of the mode shaft 36 is a D-shaped shaft, and after the mode shifter lever 25 is assembled with the mode shaft 36, a user can drive the mode shaft 36 by shifting the mode shifter lever 25; as shown in fig. 17, under the action of the mode shaft 36, the worm/helical gear 39 is meshed with the toothed structure on the driving wheel 40, and when the gear motor 37 drives the worm/helical gear 39 to rotate, the driving wheel 40 rotates under the interaction of the toothed structure, so that the square shaft 30 is driven to rotate electrically; as shown in fig. 18, the mode shaft 36 and the mode shift lever 25 are changed in position, and the worm/bevel gear 39 and the toothed structure on the driving wheel 40 are no longer in meshing relationship under the action of the mode shaft 36 and the tension spring 44, so that a user can manually rotate the handle 24, thereby manually driving the square shaft 30 to rotate.

As shown in fig. 19 to 21, when the window sash electric handle is mounted, the window sash electric handle can be mounted on the window sash frame 22 by removing the panel 28 and the mode deflector rod 28, inserting the signal wire and using the countersunk head screw C43, and then the window sash electric handle can be completed by mounting the panel 28 and the mode deflector rod 25. Because the mounting mode of the electric window fan handle is basically consistent with the traditional manual square shaft handle mounting mode, the mounting and using cost of the electric window fan handle is reduced. And (3) opening holes according to the standard mounting holes of the manual square shaft handle on the newly manufactured window frame, and simultaneously adding signal wire holes. And (3) directly removing the manual square shaft handle on the finished window, and simultaneously adding the electric window sash handle signal line hole 42. As shown in fig. 22, the window frame mounting hole in the mounting diagram is shown in the diagram, and a common square shaft handle mounting hole standard is listed, and the electric window fan handle can directly replace the standard square shaft handle, but the electric window fan handle is not only applicable to the mounting hole standard. Therefore, the traditional window manufacturer can use the electric window sash handle without spending more cost in the window manufacturing process, thereby improving the value of the window.

As shown in fig. 17 and 18, the circuit board 12 is provided with a WiFi module (ESP 8266) 13 and a radio frequency module (433 MHz) 14, the WiFi module 13 is used for networking control of the window sash electric handle, and the WiFi module 14 can be directly connected with a router or an intelligent gateway, so that higher-level linkage control is realized. The rf module 14 is used for short-range remote control of the electric window sash handle, and the remote control device for the electric window sash handle may be an 86 panel rf remote control or a mobile handheld remote control, i.e. the rf remote control ii of fig. 1.

When the electric handle of the window sash is arranged on the inwardly opened window, the electric handle can drive the original hardware driver on the window sash to switch the inwardly opened, inwardly opened and locked modes. Compared with the traditional electric window, the electric window is not in two modes of flat-open and locking any more, so that a better inward tilting state can be realized by using the electric handle.

The electric handle of the window sash can be used singly or in combination with the electric window opener: the window can be controlled to be opened or closed conveniently. (the user can control the window remotely through the network control, or like traditional window manual open and shut.) the control window is better scientific and reasonable. When the electric window opener and the electric handle of the window sash are installed on the inward opening and inward tilting window to be used, the handle 24 is first required to be manually or electrically rotated to realize the horizontal opening or inward tilting state shown in fig. 23, and then the electric window opener can be opened to realize the corresponding inward opening or inward tilting function of the electric window opener, as shown in fig. 4, 6 and 8.

The window sash electric handle is in a shape without complex modification process to a window frame, and is installed in the same manner as a traditional square shaft handle. The use of the electric handle of the window sash can not influence the functions of hardware on the window and the structural safety of the window. Meanwhile, the process of switching the window sash mode (opening and closing) of the window sash electric handle is changed from the traditional manual switching to the electric switching. The safety problem that the original handle and hardware fail due to the fact that an electric window opener is only additionally arranged on a common window is solved.

The invention can be applied to the following industries using inwardly opened and inverted windows. For example: the high-level window is higher or too far away from the installation position of the window, and the window is not touched by manpower alone. The window is too heavy, and it is laborious to open or close, and manual switch uses inconveniently. The floor has fire-fighting smoke-discharging window with fire-fighting linkage ventilation requirement. There are weather open/close window requirements such as: and the window needs to be automatically closed when the warehouse rains. The indoor constant temperature requirement is that: windows of greenhouses for vegetables or flowers. The indoor temperature is required, and the temperature is too high, such as: and a window of the communication machine room. Strict requirements on indoor air index are met, and timely timing ventilation is needed. The indoor needs proper brightness and needs to adjust the angle of the shutter. Windows require a tighter closing seal force, such as a skylight that is more tightly closed for rain protection. Other special occasions, such as factories and workshops of chemical industry, dust and the like, need to be ventilated in time. Green, intelligent, energy-saving modern high-rise buildings, such as curtain wall windows, etc. Building automatic control, intelligent home control, and the like.
