Description

Technical Field

[0001] The invention relates to a garden control system, in particular to a garden management control system based on a network. Background Art

[0002] As a landscape system, the garden system can be used as an auxiliary facility for home life and as a convenient activity place for the city. It brings a high-quality life atmosphere to people's home life and provides citizens with a leisure and pleasant activity place. As the main covering of the garden, the maintenance and management level of green plants determines whether the plants can survive normally and grow healthily after planting, and whether the ecological and artistic effects of the plants can be exerted. In the garden system, there are relatively many types of green plants. For some precious plant varieties, it is relatively difficult to take care of them and requires relatively high cultivation technology. Unless there is a dedicated person to perform daily maintenance on the garden system, it is difficult to ensure the normal and healthy growth of green plants.

[0003] Now, there is a control system on the market for the operation of garden systems, which is used to automatically control some electrical appliances installed in the garden system, which can greatly liberate manpower and realize the automation of garden system operation. The existing control system can be applied to indoor garden systems, but the control is relatively troublesome and the degree of automation is relatively insufficient. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a network-based garden management and control system, which is easy to use and has a high degree of automation.

[0005] Technical measures taken to solve the technical problems: A network-based garden management control system, including a terminal, a platform software is installed on the terminal, and a small program for garden management is embedded in the platform software, characterized in that:

[0006] It also includes a controller, an identity QR code that identifies the identity of the controller, and a binding password. When the terminal and the controller are bound to each other, the terminal and the controller need to be connected to the same WI-FI with a clear name and login password at the same time, and the Bluetooth of the terminal remains turned on; the terminal is used to enter the mini program in the platform software, and the identity QR code is scanned using the scanning function in the mini program. The binding password is entered in the interface displayed next by the terminal, so that the terminal and the controller are bound to each other, so that the controller can be controlled in the mini program using the terminal;

[0007] A signal receiver and several groups of control circuits are arranged in the controller. The signal receiver is used to receive control signals sent due to the control operation of the terminal. Each group of control circuits corresponds to a signal output terminal of the signal receiver. Each group of control circuits controls the operation of a relay. Each relay controls whether a terminal is energized or not. The terminal is used for external electrical appliances. The control circuit includes an optocoupler and a field effect transistor. The signal receiver will send a signal to the corresponding optocoupler according to the received control signal. The optocoupler controls the corresponding relay through the field effect transistor.

[0008] The terminal can be a desktop computer or a laptop computer, or a tablet or a mobile phone. In general applications, smart phones are more commonly used. The operator can remotely control the garden system through the terminal based on the network. The platform software is generally WeChat or Alipay, etc., and a garden management applet is implanted in the platform software. The applet relies on the platform software and is an application that can be used without downloading and installing. Users can enter the target applet by scanning or searching the platform software. The method of compiling the applet is a prior art. For example, Publication No.: CN 114185551A discloses a method for compiling the applet; Publication No.: CN 114217874 A discloses a method for generating the applet. The identity QR code is usually pasted or processed on the controller, and the identity QR code and the controller are uniquely corresponding.

[0009] Furthermore, when scanning the identity QR code, the terminal will display the WI-FI name in the interface and require the login password to be entered in the password field to achieve the binding of the terminal and the controller. This requires the binding between the terminal and the controller to be performed on site to avoid confusion when binding between the terminal and the controller, which can effectively improve the safety of use.

[0010] Furthermore, the applet has a sharing function. When the terminal clicks on the applet to enter the sharing function, a shared QR code corresponding to the controller will pop up. Other terminals can use the scanning function in their garden management applet to scan the shared QR code, and then use the applet to control the controller. The generated shared QR code is generated by the QR code generator built into the applet, so that the correspondence between family members and controllers can be added, and family members can control the garden system online through the controller based on the network, so that family members can experience the fun of garden management together, which is conducive to improving the mutual assistance and coordination of the family, and helping the family to live in harmony and increase the fun of family affection.

[0011] Furthermore, the mini program has a hosting function. By using the terminal, you can click on the hosting function in the mini program to complete the hosting setting, so that the controller periodically controls the operation of the corresponding electrical appliances. In this mode, the garden system can operate automatically without manual active control, so that the garden operator can selectively adjust different working modes according to his actual working conditions.

[0012] Furthermore, the signal receiver is a control chip of model CC3235MODSF12MOB.

[0013] Furthermore, the control chip has a signal receiving terminal, which is communicatively connected to the wiring terminal and is used to sense the electrical appliance connected to the wiring terminal. This facilitates the connection between the electrical appliance and the wiring terminal. The electrical appliance only needs to be connected to any single wiring terminal, and the control chip can sense the specific type of the electrical appliance, which will correspond to the specific control icon in the mini program. Of course, in the case where a signal receiving terminal is not set, each electrical appliance in the garden system can be connected to the corresponding wiring terminal in a pre-set order. At this time, the wiring terminal generally needs to be marked so that the electrical appliance can be quickly connected to the corresponding wiring terminal. It can also be that when connecting an electrical appliance, it is necessary to manually match the electrical appliance and the connected terminal position with the corresponding touch mode control button in the mini program in the mini program so that accurate control can be achieved in the future.

[0014] Furthermore, an AC-DC circuit is provided in the controller, which is used to convert the power supply voltage into low-voltage direct current to power the control circuit; the optical coupler has four pins, the first pin and the second pin are connected, the third pin and the fourth pin are connected, and the first and second pins are blocked from the third and fourth pins; wherein, the first pin is connected to direct current, the second pin is connected to the signal output terminal on the signal transmitter; the third pin is connected to the field effect tube, and the fourth pin is connected to direct current; driven by the direct current on the first pin, after the second pin receives the signal, it will cause the field effect tube to conduct, and guide the direct current on the fourth pin to the relay, so that the relay controls the corresponding power supply connector to be energized. The first and second pins are physically blocked from the third and fourth pins, which can realize the forward transmission of the signal, and effectively block the interference or reverse high voltage generated by the electrical appliances and electrical components when working in other circuits, which can not only ensure the normal communication, but also effectively avoid the influence of the reverse high voltage on the circuit, and ensure the safety of the circuit operation.

[0015] Furthermore, a varistor is connected in series between the live wire and the neutral wire of the terminal, and the conduction voltage of the varistor is higher than 380V. Electrical appliances such as water pumps often generate instantaneous voltages of up to thousands of V at the moment of starting or shutting down. By providing a varistor, when high voltage is generated, the high voltage will be absorbed by the conduction of the varistor to prevent the high voltage from being fed back to the external circuit and causing some electrical components in the circuit to be broken down and damaged. The conduction voltage of the varistor is higher than 380V. When it is less than or equal to 380V, the varistor is equivalent to an insulator and will not affect the normal application of the terminal.

[0016] Furthermore, a capacitor and a resistor are connected in series between the live wire and the neutral wire of the connection terminal, and the capacitor and the resistor are connected in parallel with the varistor. Although the voltage generated by the electrical appliance when starting and stopping is relatively high, its energy is relatively low. When the voltage is less than the conduction voltage of the varistor but greater than 380V, it will be absorbed by the capacitor, thereby preventing the voltage from being fed back to the external circuit. This allows the high voltage generated when the electrical appliance is started and stopped to be reduced according to different application scenarios, which can effectively ensure the operational safety of the control system.

[0017] Furthermore, a rain sensor is provided on the controller, and the rain sensor includes a shell, and a notch is provided on an outer surface of the shell, the notch is open to the outside, and a movable plate is provided in the notch, and two separated electrodes are provided on the surface of the movable plate facing the outside, and the two electrodes are respectively connected to the signal receiver through two leads; the movable plate is connected to the top column, and the outer peripheral surface of the cam is in conflict with the outer end of the top column, and the cam is connected to the adjustment shaft, and the bimetallic strip acts on the adjustment shaft so that as the temperature rises, the bimetallic strip prompts the adjustment shaft to rotate, and the depth of the notch increases. The rain sensor is used to sense whether it is raining outside, so as to avoid starting the hydraulic pump to supply water to green plants or foliar fertilizer and pesticide when it rains, which is particularly effective in the hosting mode of the management and control system. By setting up a rain sensor, the control system can be further adapted to outdoor applications, so that the management system has a wide range of applications. In addition, by arranging the structure to drive the movable plate in the notch, the depth of the notch changes accordingly with the change of temperature. At high temperature, the notch is deep, and relatively more rainwater can be stored; while at low temperature, the depth of the notch becomes smaller, and relatively less rainwater can be stored. As a result, the time for the accumulated water to evaporate is not much different, so that the rainwater sensor can adapt well to the temperature change of the outside world, and the work of the sprinkler equipment in the garden system is highly compatible with the environment.

[0018] The present invention has the following beneficial effects: the garden management and control system can realize automatic control of the garden system, especially remote control, so that the garden system can be managed conveniently, which can greatly liberate manpower and fully experience the fun of garden management. The garden management and control system can utilize the applet implanted in the platform software on the terminal, and can realize the corresponding electrical appliances in the garden system to work through simple operations, which is very easy to operate. When the terminal and the controller are bound to each other, they need to be matched on the same WI-FI. On the one hand, it can ensure the uniqueness of the match between the terminal and the controller; on the other hand, when matching between the terminal and the controller, there are certain space requirements. The terminal and the controller can only be matched face to face in a limited area, so as to ensure the security of the matching and binding between them, so as to avoid malicious binding by unrelated personnel.

[0019] In addition, when matching, the matching binding between the terminal and the controller is exclusive. After one terminal is successfully bound to the controller, the other terminal cannot be bound to the controller. Only after the terminal is unbound, the other terminal can be bound to the controller by scanning the identity QR code, which can ensure that the owner or operator of the garden system actually has the management rights. For other co-managers, they can participate in the management by sharing the QR code with the main controller, which brings convenience to the allocation of management rights for managers in the setting.

[0032] This network-based garden management and control system is used to control the garden system. There are many electrical appliances in the garden system, such as water pump water supply devices, spray devices for watering or fertilizing green plants, spraying devices for applying pesticides, lighting lamps for supplementing green plant lighting, atmosphere lights for increasing the effect of garden areas, devices for feeding green plant roots, monitoring and security equipment, etc. This garden management and control system does not require people to go to the site, that is, it can control these electrical appliances. More specifically, it controls the electrical appliances to turn on or off the power supply in the appropriate time period to start or shut down the target electrical appliances. This garden management and control system can realize remote operation control. Therefore, when controlling, it must be based on the network. The network can be an intranet, Internet, Global System of Mobilecommunication (GSM), Wideband Code Division Multiple Access (WCDMA), 4G network, 5G network, Bluetooth, Wi-Fi and other wireless or wired networks.

[0033] The hardware structure of this garden control management system includes a terminal and a controller. The terminal usually refers to a smart phone. The controller serves as a link between the terminal and the electrical appliances, realizes the execution of terminal instructions, and controls the work of the electrical appliances. The terminal is installed with platform software. The platform software used more often is WeChat, and a small program for garden management is embedded in the platform software. The small program has a clear name. You can search in the small program column of the platform software, or scan the QR code corresponding to the small program, and you can smoothly enter the corresponding small program. Correspondingly, a plurality of wiring terminals are set on the controller, and one wiring terminal is connected to an electrical appliance or a class of electrical appliances through a power cord.

[0034] The controller is box-shaped, with a circuit board inside. Multiple terminals are arranged in a row at the edge of the circuit board. The power cord of the appliance is connected to the terminal from one side of the controller, and the power cord of one appliance is connected to one terminal. The circuit on the circuit board is driven by an external power supply, which needs to be connected to the circuit board through a device such as a Figure 8 The AC-DC circuit shown in the figure is converted into low-voltage direct current of several voltage values, and then the power supply and drive of each part of the circuit are realized. On the circuit board, a group of control circuits are arranged upstream of each terminal, and are used to control whether the terminal can be connected to the external power supply, so as to supply power to the electrical appliance or cut off the power supply of the electrical appliance.

[0035] Each controller is equipped with an identity QR code generated by the QR code generator, and each controller needs to set a login password in the applet according to the identity QR code when it leaves the factory. The identity QR code and login password can be pasted on the controller, or the identity QR code can be directly marked on the controller by laser.

[0036] When binding the terminal and the controller, the terminal and the controller need to be connected to the same WI-FI with a clear name and login password at the same time, and the terminal's Bluetooth should be turned on; use the terminal to enter the applet in the platform software, use the scanning function in the applet to scan the identity QR code, and enter the binding password and the WI-FI login password in the interface displayed by the terminal next, so that the terminal and the controller are bound accordingly, and the controller can be controlled in the applet using the terminal. For more stringent requirements, when scanning the identity QR code, the WI-FI name will be displayed in the interface displayed by the terminal, and the login password will be required to be entered in the password field, so that the terminal and the controller can be bound.

[0037] The applet has a sharing function. When you use a terminal to click on the sharing function in the applet, a shared QR code corresponding to the controller will pop up. Other terminals can use the scanning function in their garden management applet to scan the shared QR code and use the applet to control the controller. In order to adapt to the working hours of managers, the applet has a hosting function. When managers are busy, they can use the terminal to click on the hosting function in the applet to complete the hosting settings, so that the controller periodically controls the operation of the corresponding electrical appliances.

[0038] A signal receiver is set in the controller to receive the control signal sent by the terminal through the network. The signal receiver is a control chip, whose model is: CC3235MODSF12MOB control chip, manufactured by Texas Instruments. The control chip can process the signal sent by the terminal and then send instructions to the outside. The control chip has Figure 1The WI-FI module shown operates the corresponding control button on the mobile phone applet, causing the Internet server to generate a logic control level and send it to the WI-FI module. Figure 2 The I / O interface circuit of the control chip is shown in the figure. It has 16 pins from W0 to W15. One pin is used as a signal output terminal, and each group of control circuits corresponds to a signal output terminal. The WI-FI module sends signals to the corresponding group of control circuits through the corresponding pins in the I / O interface according to the logic control level. Each group of control circuits controls a relay to work. After the relay works, the corresponding terminal can be powered on or off.

[0039] Figure 1 , 2 TX is the signal sent by the control chip to the outside, and RX is the feedback signal from the appliance to the control chip to determine the specific appliance connected to the corresponding terminal, so as to facilitate the correct correspondence between the buttons on the terminal and the appliance. All terminals can be electrically connected to the control chip. When a terminal is connected to an appliance, the control chip can sense the characteristics of the connected appliance, so that the appliance can correspond to the corresponding control button in the applet. Without setting the feedback signal, the corresponding appliance can be connected to the corresponding connection terminal in sequence. In this case, the wiring position requirements of the appliance cannot be wrong.

[0040] Figure 3 What is shown is the RS232 interface circuit. The TX signal and the RX signal both pass through the interface circuit, and the RX and TX signals can be processed to remove some interference signals, and the RX signal and the TX signal can be amplified so as to stably transmit and communicate with the outside.

[0041] Figure 4 The optical isolation drive circuit is shown in Figure 5 Show Figure 4 A magnified image of one of the cells; Figure 6 shows the relay drive circuit, Figure 7 Shows Figure 6 A magnified view of a unit in the embodiment. The control circuit comprises Figure 5 A unit in Figure 7 A unit in the Figure 4 , 6 , several groups of control circuits are arranged in a row, and correspondingly, the terminals are also arranged in a row. The figure shows that there are sixteen groups of control circuits and sixteen terminals, and the terminals are marked as PPn (n=1-16) in the figure. In actual application, the control circuits and terminals may increase or decrease.

[0042] See Figure 4The main functional structures in the optical isolation drive circuit include the optical coupler OPx (x=1-16) and the field effect transistor Qy (y=1-16). Figure 5 Taking a unit as an example, the optocoupler OP1 has four pins, the first pin and the second pin are connected, the third pin and the fourth pin are connected, and the first and second pins are physically blocked from the third and fourth pins. A light-emitting diode is also set between the first pin, the second pin and the third and fourth pins to show whether the field effect tube is in working state. Among them, the first pin is connected to +5V DC as the working current of the field effect tube Q1; the second pin is connected to the signal output terminal on the control chip, Figure 4 In the embodiment, the second pins of the sixteen effect transistors Qy correspond to the signal output terminals W0-W15 on the control chip. The fourth pin is connected to the +24V direct current on the AC-DC circuit, and the third pin is connected to the field effect transistor Q1. Driven by the direct current on the first pin, the second pin receives the signal output from the signal output terminal W0, which will cause the field effect transistor Q1 to conduct, and the output terminal J0 on the field effect transistor Q1 will carry a +24V voltage, which will be applied to the relay drive circuit, so that the corresponding terminal of the relay control is charged.

[0043] Figure 6 16 relays are shown in a row, namely relays RL1-RL16, and the 16 relays correspond to eight groups of terminals, namely terminal groups PP1-PP8, and one group of terminals is composed of two terminals connected together. One terminal is connected to a neutral line N1 and a live line L1 of an external power supply, and the live line L1 is connected to the corresponding relay. When the relay is started, the corresponding live line L1 is conducted to the terminal.

[0044] Figure 7 There are two relays RL1, 2, and the two relays are respectively connected with light emitting diodes LD1, 2 and diodes RD1, 2. When the relay conducts the live wire L1, the corresponding light emitting diodes light up to reflect the working condition of the relay. Figure 4The output terminals on the field effect tubes Q1-Q16 correspond to J0-J15, and these sixteen output terminals are connected to the relays RL1-RL16 respectively, so as to realize the one-to-one control of the relays by the field effect tubes. When the field effect tube Q1 is turned on, the switch RELAY4P on the relay RL1 will be closed, thereby turning on the live wire L1 of the external power supply, so that the corresponding terminal is energized. In order to increase the stability of use, a varistor VRI (I=1-16) is connected in series between the neutral wire N1 and the live wire L1 corresponding to one terminal, and the conduction voltage of the varistor is higher than 380V. A resistor and capacitor RC are also connected in series between the live wire L1 and the neutral wire N1. The conduction voltage of the varistor indicated in the figure is 560V, that is, when the induced voltage generated by the electrical appliance is greater than or equal to 560V when starting or shutting down the electrical appliance, the varistor will be turned on and absorb the induced voltage; when the induced voltage generated is lower than 560V, it will be absorbed by the capacitor in the resistor and capacitor in an energy storage manner.

[0045] In order to improve the automation of garden system control, multiple sensors can be set in the garden system to sense some physical parameters in the garden system environment, such as temperature, humidity, water level, etc. These sensors are connected to the control card to provide a reference for the start-up of electrical appliances. Fig. 9 The interface circuit of the sensor is shown in FIG. Fig. 9 The temperature sensor and humidity sensor are only shown as examples. Sensors with other structures can also be set. These sensors feed back to the control chip via RX signals.

When it rains outside, some rainwater will accumulate in the notch 3.

[0047] Two separated electrodes 4 are provided on the bottom surface of the notch 3.

The two electrodes 4 are electrically connected to two leads respectively, and these two leads are connected to the circuit board in the housing 1, and the circuit board is electrically connected to the control chip in the controller through a wire. The electrode 4 is a flat sheet, generally made of copper or stainless steel, and the electrode 4 is fixed on the bottom surface of the notch 3. The single electrode 4 is comb-shaped as a whole, with a plurality of electric teeth 6 arranged in parallel and spaced apart. The electric teeth 6 on the two electrodes 4 are staggered together, and an electric tooth 6 on the other electrode 4 is interlaced in the gap between the adjacent two electric teeth 6 on one electrode 4. There is a physical gap between the two electrodes 4, and a partition 5 is formed between the two electrodes 4 due to the separation. The partition 5 extends equally wide between the two electrodes 4 in the direction of the rectangular wave.

[0048] A movable plate 7 is provided in the recess 3. The size of the movable plate 7 is substantially the same as the cross-sectional size of the recess 3. The movable plate 7 may be made of rubber material or a rubber plate composited on a hard substrate, so that a liquid seal is formed between the movable plate 7 and the inner wall of the recess 3. The front surface of the movable plate 7 constitutes the bottom surface of the recess 3. The movable plate 7 is in transmission connection with the adjustment mechanism. The depth of the recess 3 can be changed by the action of the adjustment mechanism on the movable plate 7.

The adjustment mechanism includes a cam 11, and the outer peripheral surface of the cam 11 is in conflict with the lower end surface of the top column 9. The cam 11 is connected to the adjustment shaft. The cam 11 is arranged in the housing 1, and the outer end of the adjustment shaft can be extended to the outside of the housing 1. The adjustment shaft can be adjusted manually; or the adjustment shaft can be driven to rotate by a bimetallic temperature sensing strip. When the external temperature changes, due to the different thermal expansion systems of the two different metals, the curvature of the bimetallic temperature sensing strip will change. The bimetallic temperature sensing strip acts on the adjustment shaft to make the adjustment shaft drive the cam 11 to rotate, so that as the temperature rises, the depth of the notch 3 increases; when the temperature decreases, the depth of the notch 3 decreases.

[0050] In the housing 1, a spring 12 is sleeved on the outer periphery of the top column 9, and a nut 10 is provided at the lower end of the top column 9.
