Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

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

a window sash electric control system is shown in figure 1, and a system structure block diagram shows a plurality of electric appliance linkage modes. The linkage equipment listed in the system comprises an electric curtain window part, an electric window opener, a window sash 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 rainwater 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 are composed 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. The App can set air and environmental parameters, and the system can intelligently and automatically adjust the linkage working scheme of the electrical equipment according to the connected equipment. APP can send the linkage scheme to the intelligent gateway through the network, and the intelligent gateway stores the scheme and then starts linkage control work.

The system has the advantages that the system can be separated from the internet to perform linkage control work in special use, and is more convenient and faster to use. Control to the window has compared in traditional mode and has increased the electronic handle of casement, control casement that can be more reasonable can switch the mode that the casement opened to the system window, can use original hardware locking window on the casement, need not the structure repacking to the window, and is safer.

According to the system, the intelligent gateway is provided with an independent control system, and the system can also perform linkage control in a non-networking state. The window is simultaneously provided with the electric window opener and the electric window sash handle for combined work, and the window is more reasonably controlled.

The system is based on the control of the electric window opener on the opening and closing of the window sash. Compared with the prior art, the intelligent indoor environment adjusting control system has the advantages that the single linkage work can be realized only by the single function, and the window opener which is a key device in the system has more defects, so that the control system for intelligently adjusting the indoor environment is created, and the required indoor environment can be realized or approached 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 the window opener, and covers part of electrical equipment which can work in linkage with the window opener. The system is suitable for adjusting various indoor environments and provides convenience for life production.

Specifically, realized the linkage of casement transmission hardware and electronic ware of windowing through electronic handle, very big degree has got simplified the process that traditional casement electromotion was reformed transform. The control system combines various external electrical equipment around the electric window, can support various linkage working schemes, and can provide convenience for life.

In the above-mentioned parts, except that electronic ware, the electronic handle of casement of windowing, all can be based on prior art, for example the window curtain part of electronic (window) curtain is based on the window curtain that automatic expansion, draw in such as electronic open and shut curtain series, electronic lift curtain series that parts such as motor, controller, pulley, belt constitute. Other components of the system are described further below:

1. the gateway functions as follows: 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 among different network segments and protocols, which is similar to a translation officer. The difference is that the router is a networking device which constructs the bottom layer support of the whole home internal wireless WiFi hotspot local area network and is arranged between an intranet (local area network) and an extranet (internet) or a superior network segment, and the gateway belongs to data switching equipment among different transmission protocols in the intranet. The intelligent home comprises wireless connection modes which are common in the smart home, WIFI, Bluetooth, zigbee and radio frequency 315/433.

(1): the radio frequency 315/433 is the earliest and most common scheme in the field of smart home, and has the advantages of simple design and low cost, but the fatal weakness is that bidirectional real-time feedback communication cannot be realized, namely, the state of a controlled device cannot be reflected in real time after a control signal is sent, and the scheme is definitely rejected. (2): WiFi has the characteristics of more devices, wide range and high speed, but the WiFi is not suitable for being used as a low-power-consumption sensor due to large power consumption. Bluetooth has the characteristics of low power consumption, good stability and open protocol, but multiple networks are troublesome 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, the ZigBee can work in 2.4GH (global), the highest 250Kbit/s and the lowest 20Kbit/s, the transmission distance is between 10 and 75M, the safety of the ZigBee is well recognized, an AES-128 encryption mode is adopted, and in addition, the ZigBee network has strong self-organization network and self-healing capability.

2. What are Bluetooth Low Energy (BLE) and bluetooth gateways? Bluetooth Low Energy (or Bluetooth LE, BLE) is also called Bluetooth Low Energy, is a personal wireless local area network technology, and compared with the classic Bluetooth used in devices such as mobile phones, earphones, televisions, PCs or sound equipment, the Bluetooth Low Energy (or Bluetooth LE, BLE) has lower power consumption and longer transmission distance, and is mainly applied to some smart home devices powered by batteries. Due to the consideration of power consumption, cost, safety and the like, generally, the BLE sub-device itself is not integrated with the WiFi module, so that the BLE sub-device cannot be directly and independently connected to the router and the external network, and the BLE sub-device can be realized by means of the bluetooth gateway device.

3. What are the Zigbee transport protocols and Zigbee gateways? ZigBee is also called as Zigbee, 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 directly connect the router through WiFi, but need to relay with the help of a gateway? It is theoretically possible if all devices are directly connected to the router in a WiFi manner without using a gateway for data transfer. However, for the whole smart home system network, if only a few devices participate, there is no problem, but with the continuous increase of various new devices, there will inevitably be many obvious problems: first, if the entire network has only one router hub, it may not be able to support such a large device base, and although WiFi has a stronger transmission capability, dead and dead zones may exist for a house with a large area and multiple rooms. Even if the number of the router access devices is not limited and the whole house realizes the perfect coverage of the WiFi without dead angles, congestion and interference are likely to be caused by excessive device access and transmission, so that the operation efficiency and the actual experience of the whole network are affected; secondly, the power consumption of the equipment adopting WiFi transmission on electric energy is increased, so that more equipment cannot work independently without being bound by a power line, even if a battery with larger capacity is adopted, the equipment needs to be replaced or charged frequently, and huge limitation and influence are caused on the equipment size, research and development difficulty, maintenance cost, flexibility, convenience and the like; if all transmission processes are finished by WiFi, a router and an external network, and only a unique data exchange center exists in the network, all control and scenes cannot be realized once the network has problems, all switches depending on WiFi transmission and linkage of safety defense deployment and other equipment are similar to a nominal one; for intelligent equipment with higher safety requirements, such as a fingerprint lock, if the intelligent equipment is directly connected to an intranet and an extranet through WiFi (wireless fidelity), even if a more advanced encryption transmission protocol and process are adopted, fatal potential safety hazards can be brought, and the risks of illegal monitoring, tampering and control are higher; more importantly, if all the devices are implanted with the WiFi transmission chip, the development cost and the hardware overhead are gradually increased, and meanwhile, the deployment budget and the threshold of the smart home are also increased. And the command transmission message between some devices and the router is usually only a few KB, which is a waste for the communication capability of WiFi. In summary, it is only the gateway and the multi-protocol relay that are adopted to implement data transmission and exchange of devices, which is the most efficient and feasible solution in the smart home system currently and for a long time in the future. With the gradual popularization of the Zigbee 3.0 and bluetooth gateway technologies, it is believed that the multimode gateway will become an indispensable important hardware component in the future deployment and upgrade of the smart home system, and can embody and exert more excellent core value and actual effect.

5. The built-in communication chip model of common intelligent household products: according to different functions of products, the requirements of the products on network communication are different. Radio frequency, Bluetooth and zigbee modules are commonly used for products with low power consumption, large quantity and small data volume. Products with large data transmission quantity commonly use WiFi modules for data transmission. Electric curtain: the electric curtain needs to meet outdoor remote networking control and indoor short-range remote control of a user, and during remote networking control, a large amount of data information such as opening size and a timing switch can be included, so that 2 WiFi and radio frequency modules are arranged in a common product. The WiFi module is typically ESP8266 and the radio frequency module is typically CC1101 wireless module (433 MHz). Electric window opener: the electric window opener needs to meet outdoor remote networking control and indoor short-range remote control of a user, and generally comprises a large amount of data information such as window sash opening size and a timing switch window during remote networking control, so that 2 types of WiFi and radio frequency modules are arranged in a common product. The WiFi module is typically ESP8266 and the radio frequency module is typically CC1101 wireless module (433 MHz). Electric handle of window sash: the electric handle of the window sash needs to meet the requirements of outdoor remote networking control and indoor short-range remote control of a user, and during remote networking control, the electric handle generally contains a large amount of data information such as window sash modes (inner reversing, inner opening and locking) and timing switch windows, so that 2 kinds of WiFi and radio frequency modules are arranged in a general product. The WiFi module is typically ESP8266 and the radio frequency module is typically CC1101 wireless 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 of a user, the air treatment device generally comprises a working air quantity gear, a timing switch air treatment function, uploading air quality data and other large amount of data information, and a control panel is generally arranged on the product, so that the product is only provided with a WiFi module. The WiFi module is typically ESP 8266. Air detection device: the air quality detector (CN201920582419.0) is a novel air detection device, a WiFi module is arranged in the air quality detector, detected data such as air quality can be sent to a user through a network in real time, data can be transmitted to the intelligent home control system, the intelligent home control system can control the intelligent home equipment to work according to the data, and therefore the environment is automatically improved. The WiFi module is typically ESP 8266. Scene rain detection device: the wind, light and rain detection device usually sends simple data to the outside, and the product works outdoors, so that external power supply is not adopted, and the power is usually supplied by an internal battery. The low power product location determines the communication mode, so the product only has a bluetooth module. The bluetooth module is typically NRF 51802.

6. The scheme of the multifunctional gateway chip comprises the following steps: ZigBee: the multifunctional gateway adopts an industrial ZigBee radio frequency chip (JN5168) based on NXP to carry out networking communication; WiFi: ESP-12F; bluetooth: HC-05; radio frequency: CC1101(433 MHz).

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

As shown in fig. 2-3, the upper cover plate 1 and the housing 2 are assembled by a screw a 5; the front panel 3 and the housing 2 are assembled by a screw C7; the screw B6 is used for fixing the electric window opener main body on 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 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 unit 10 and the connecting rod a 11. When the electromagnetic clutch 8 is powered on, the gear set 10 is rigidly connected with the connecting rod a11, and at the moment, the motor 9 drives the connecting rod a11 through the gear set 10 to drive the window sash to move, and at the moment, the window sash is not allowed to be opened or closed manually. When the electromagnetic clutch 8 is powered off, the gear set 10 is flexibly connected with the connecting rod A11, weak damping force exists between the gear set 10 and the connecting rod A11, the damping force is used for preventing the window sash from swinging under the action of wind, and the window sash is allowed to be opened and closed manually at the moment. When the electric window opener receives a window opening and closing signal, the electromagnetic clutch 8 is powered on, and when the window opening and closing action is finished, the electromagnetic clutch 8 is powered off; the screw D16 is used to fix 17 the guide 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 'window opener inward opening/inward reversing/locking mode state' of fig. 4-12, the multi-section connecting rod multi-axis structure realizes the perfect adaptation of the inward reversing inward opening window.

As shown in fig. 2, the circuit board 12 is provided with a WiFi module (ESP8266)13 and a radio frequency module (433MHz)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 radio frequency module 14 is used for short-range remote control of the electric window opener, and the remote control device of the electric window opener can be 86 panel type radio frequency remote control or a mobile handheld remote controller, namely a radio frequency remote controller II in fig. 1.

Above-mentioned electronic ware of windowing, when opening or closing through cell-phone APP or II remote controls of radio frequency remote controller, when connecting rod B15 extends or contracts when target in place, because the electric current grow of motor 9, detect through its circuit board this moment to the outage of control motor 9 stops.

The electric window opener is in an opening/inward reversing/locking mode state, the movement state of the electric window opener is shown in figures 10-12, the left side is a vertical figure, and the right side is a figure obtained by viewing from a position A in the vertical figure. Compared with the prior electric window opener which is mainly in a chain type, the window opener is self-locking. After the traditional window is provided with the electric window opener, a user can not control the window sash to open and close in a manual mode, the window sash is completely controlled by the electric window opener, and the original handle, transmission box and window lock can fail. The self-locking characteristic of the window opener replaces a hardware structure lock of a window sash, the window sash cannot be locked through original hardware, and the safety of the window sash is greatly reduced. The function of the conventional electric window opener is also limited, and the window can be simply opened or closed. When the window opener is installed on a multifunctional system window (top-hung, inward-falling, flat-open and the like), the window opener cannot realize all functions of the system window due to the fact that the handle of the window cannot be controlled. The electric window opener has a networking function, and a user can remotely control the opening and closing of a window. And simultaneously, the opening and closing of the window can be controlled better and more conveniently. (the user can control the window remotely and empty through a network or manually open and close like a traditional window.) the window control is more 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 influenced during use.) thereby solving the problem of single window sash opening mode of the traditional electric window opener. And the problem that a user cannot manually open and close the window sash when 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 opening and inward falling of a window sash. The use of which does not affect the function of the hardware on the window. When power failure or window opener mechanical failure occurs, a user can manually open and close the window, and the structural safety of the window cannot be influenced.

In the system, the electric handle of the window sash is shown in fig. 13 and 14, and the shape of the electric handle is similar to that of a fingerprint door lock. The handle 24 has the same function as a traditional handle and is used for switching the window sash modes; the square shaft 30 is a power output shaft and is used for driving a hardware transmission box in the window frame 41 to work. The specification of the square shaft 30 is the mainstream general specification (the section size is 7 x 7mm) on the market and is consistent with the output shaft of the traditional handle, so that the hardware transmission box in the window frame 41 does not need to be specially customized, and the use cost of the electric handle of the window sash is reduced; the mode shift lever 25 is used for switching the manual mode and the electric mode of the electric window sash handle, and when the electric window opener or the electric window sash handle breaks down, a user can shift the mode shift lever 25 to trigger the manual mode and temporarily manually switch the window; the panel 28 is provided with a key 26 for switching the open/close mode of the window sash (inner open and inner tilt window: inner tilt, and lock; casement window: side-hung and lock).

Visible part handle 24 of outward appearance, mode driving lever 25 and square shaft 30 are movable part, and square shaft 3 can be along with handle 24's rotation and syntropy rotate, and handle 24 is also different along with the different states that can appear of window type, as shown in fig. 23, for handle angle position schematic diagram, what the schematic is 3 kinds of states on the window of opening in including the installation of the electronic handle of casement. When the window is on the side hung window, the window is not in an inward falling state.

And (4) opening holes on the newly-manufactured window frame according to the standard mounting hole of the manual square-axis handle, and simultaneously opening the signal wire holes. On the finished product window, directly pull down manual square shaft handle, add electric window fan handle signal line hole 42 simultaneously can. As shown in fig. 22, the schematic view of the window frame mounting hole in the mounting schematic view shows a common square shaft handle mounting hole standard, and the electric window sash handle can directly replace the standard square shaft handle, but the electric window sash handle is not only applicable to the mounting hole standard. Therefore, the electric window sash handle can be used by traditional window manufacturers without spending more cost in the window manufacturing process, and the value of the window is improved.

As shown in fig. 17 and 18, the circuit board 12 is provided with a WiFi module (ESP8266)13 and a radio frequency module (433MHz)14, the WiFi module 13 is used for networking control of the window sash electric handle, and the WiFi module 14 may be directly connected to a router or an intelligent gateway, so as to realize higher-level linkage control. The radio frequency module 14 is used for short-range remote control of the electric window sash handle, and remote control equipment for the electric window sash handle can be 86 panel type radio frequency remote control or a mobile handheld remote controller, namely a radio frequency remote controller II in fig. 1.

When the electric handle of the window sash is arranged on an inward opening and inward opening window, the electric handle can drive an original hardware driver on the window sash to switch between inward opening and inward opening modes and locking modes. For traditional electronic window no longer be flat-open and two kinds of modes of locking, consequently use this electronic handle can realize better interior state of falling.

This electronic handle of casement can be alone or with above-mentioned electronic ware cooperation of windowing use: the opening and closing of the window can be controlled more conveniently. (the user can control the window remotely and empty through a network or manually open and close like a traditional window.) the window control is more scientific and reasonable. (the original structure of window is not destroyed during the installation, does not influence original function and structure of user during the use.) as shown in fig. 4, 6, 8, when installing electronic ware of windowing and this casement electric handle and use on the window of opening in, when with window sash frame 22 by the closed condition to the open mode, at first need first through manual or electronic rotation handle 24, realize the handle 24 like fig. 23 after the flat-open or the fall in state, electronic ware of windowing just can open this moment, realize its corresponding interior division of opening or fall in function.

This form of casement electric handle need not to carry out complicated transformation process to the window frame, like the mounting means of traditional square-axis handle. The use of the electric handle of the window sash cannot influence the function of hardware on the window and the structural safety of the window. Meanwhile, the process of switching the window sash modes (opening and closing) of the window sash electric handle is changed from traditional manual switching to electric switching. The safety problem that an ordinary window is only additionally provided with an electric window opener to cause failure of an original handle and hardware is solved.
