One first current inductor 6 corresponds to one curtain cotton, and one second current inductor 7 corresponds to one air release port. For example, for a sunlight greenhouse, the big greenhouse curtain air release equipment is provided with two air release ports and one curtain cotton, so two second current inductors 7 are provided correspondingly, and one first current inductor 6 is provided, as shown in Figure 2 The number of the control switch 1 is determined according to the number of the current inductor. One control switch 1 corresponds to one curtain motor or air release motor. For a sunlight greenhouse, three control switches 1 are provided correspondingly.

[0050] In another example embodiment of the present application, the fault monitoring device 4 is an embedded computer.

[0051] In another example embodiment of the present application, as shown in Figure 2 The big greenhouse curtain air release automatic monitoring device further comprises a control box 8; the fault monitoring device 4, the current detection device, the switch device and the 485 bus 5 are all arranged in the control box 8.

[0052] The installation process and fault monitoring process of the automatic monitoring device for the greenhouse roller screen in practical application are further described in detail below.

[0053] The roller screen motor and the air release motor in the automatic monitoring device for the greenhouse roller screen are respectively installed on the roller screen rod and the air release rod of the roller screen air release equipment in the greenhouse (for example, a sunlight greenhouse), and are connected to the power supply line in the control box 8. The first current sensor 6 and the second current sensor 7 are installed on the power supply line of the roller screen motor and the air release motor in the control box 8, and are connected to the embedded computer in the control box 8 through the 485 bus 5.

[0054] The embedded computer in the control box 8 reads the real-time data of the first current sensor 6 and the second current sensor 7 through the 485 bus 5, and transmits the collected real-time data to the cloud server through the Ethernet, wifi or 4G / 5G signal of the embedded computer. The cloud service software in the cloud server can record and store the current signals of the corresponding roller screen motor and air release motor, and can bind the current signals with the greenhouse, the corresponding roller screen motor and the corresponding air release motor. The cloud service software can receive the current records of the corresponding roller screen motor and air release motor in the debugging mode, and fit the data in an exponential regression manner, and then calculate the current value pairs according to the sampling frequency setting through the equation to generate the normal working condition curve, and send it to the embedded computer in an array manner. The control switch 1 in the field and the embedded computer are also connected through the 485 bus 5, so that the embedded computer can collect the start and stop signals of the roller screen motor and the air release motor.

[0055] The embedded computer collects and sends the current signals of the corresponding motor to the cloud server according to the motor start and stop signals in the debugging stage, and then receives the normal working condition current parameters sent by the cloud server. In the normal operation stage, the embedded computer monitors the corresponding roller screen and air release process according to the motor start and stop signals, and compares the collected real-time current values with the normal data according to the sampling time. If the power exceeds 30% for 3 seconds continuously, the machine will be stopped and the fault will be reported, and the user will be notified by the cloud server. The mobile terminal can connect the cloud software through the data interface, debug and set the corresponding parameters.

[0056] The current signal of the roller shutter motor and the air release motor is monitored online, so as to monitor the working power of the corresponding motor, and to determine whether it is in normal working condition. First, a 485 type current sensor is installed at the power line of the roller shutter motor and the air release motor in the control box 8 respectively, the real-time reading of the current sensor is read by the embedded computer in the control box 8, and then the embedded computer transmits the read current signal to the cloud server in real time through the network (Ethernet, WiFi, 4G / 5G), the cloud server fits the current signal under normal working condition into a normal working condition curve, and then pushes it to the embedded computer in the form of an array, finally the embedded computer monitors the current load condition of the roller shutter motor and the air release motor in the working process, to determine whether it should be stopped for maintenance. In this way, when the roller shutter motor and the air release motor are not working properly, the production facilities of the sunlight greenhouse can be stopped in time to protect the production facilities of the sunlight greenhouse and reduce the safety risk.

[0057] The embedded computer in the control box 8 can read the values of the roller shutter and air release current sensors in real time through the 485 bus 5, and the roller shutter and air release switch signals on the control box 8 can be read by the embedded computer to record the working time of the roller shutter and air release motor under normal working condition, and to read the real-time values of the current sensor after the roller shutter motor and the air release motor are started, so as to reduce unnecessary system overhead. At the same time, the remotely controlled roller shutter and air release signals are also sent to the embedded computer, which has the same effect as described above.

[0058] The embedded computer in the control box 8 can transmit the collected device current values to the cloud service software in real time through the network (Ethernet, WiFi, 4G / 5G), and can transmit the collected roller shutter and air release switch signals to the cloud service software in real time, and the cloud service software can store and process these values and signal quantities.

[0059] The cloud service software of the cloud server can add specified roller shutter fan and air release motor through device ID, set the working voltage, current and rated power of the motor according to its parameters, start and stop the roller shutter fan and air release motor through the cloud service software, and be called by the mobile terminal through the security data interface to start and stop the device and set related parameters. The function modules of the cloud service software are as shown in Figure 3 The function modules of the embedded computer are as shown in Figure 4

[0060] In the device debugging stage, as shown in Figure 5 With the assistance of on-site personnel, the cloud service software can learn the current load curve of the device under normal working condition through the recorded roller shutter and air release switch signals and the collected device current signals, and send it to the embedded computer in the control box 8 in the form of discrete numerical pairs, wherein the number and time interval of the discrete numerical pairs are definable.​

[0061] During the equipment operation phase, such as Figure 6 As shown, the embedded computer in the control box 8 can compare the real-time monitored motor current value with the normal operating condition value sequence sent by the cloud service software, detect the overload operation characteristics of the equipment, and then shut down the machine to protect the equipment and production safety.

[0062] During equipment operation, the embedded computer in control box 8 detects equipment overload and shuts down the device. It then reports the data in real time and notifies the cloud service software. Upon receiving the report, the cloud service software sends a push notification to the user, specifying the greenhouse and equipment number, as well as the type of fault, urging the user to investigate.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope.
