While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The embodiment of the invention provides a processing method of an Internet of things event, which is characterized in that the action and/or the state of equipment are identified by detecting an electric signal on a power supply circuit of the equipment, and the Internet of things event is generated and reported. According to the technology of the embodiment of the invention, a module with the capability of the Internet of things is not required to be configured on the equipment, the existing equipment is not required to be changed, the event of the Internet of things is identified and reported by detecting the power supply line of the equipment, the processing processes can be realized on a device through which the power supply line of the equipment passes, the normal operation of the equipment is not influenced, the power supply lines of a plurality of pieces of equipment can be managed in a centralized manner, and the centralized connection of the Internet of things on the plurality of pieces of equipment is realized conveniently. For convenience of description, in the embodiment of the present invention, a "device" refers, without any specific case, to a device that needs to be connected to the internet of things, and may not have the capability of the internet of things itself, and therefore, cannot be connected to the internet of things by itself. The "device" may be a processing device in a factory, or may be various detection devices. In this embodiment of the present invention, the event of the internet of things may include a specific action, operation, or state executed by the device, or a detection result of the device, and these pieces of content information are all related to the device, and after being generated, the content information is reported to the remote end in the form of the event of the internet of things, so as to be further processed by the cloud end.
The means by which the power supply line passes may be capable of powering the device and have the capability of connecting directly or indirectly to the internet. As shown in fig. 1, it is a schematic structural diagram of an internet of things system according to an embodiment of the present invention. In the embodiment of the invention, the intelligent gateway can be improved to a certain extent, a power supply module for providing a power interface to the outside is added on the intelligent gateway, and as the intelligent gateway generally needs to be connected with commercial power, the intelligent gateway can supply power to the intelligent gateway and supply power to equipment at the same time through the power supply module. Specifically, a power interface may be provided on an outer shell of the intelligent gateway for plugging a power socket of the device to obtain a power supply. Because the intelligent gateway indirectly provides the function of the power socket for supplying power to the equipment, the power supply line of the equipment passes through the inside of the intelligent gateway, so that an electric signal detection module for detecting the electric signal on the power supply line can be arranged on the intelligent gateway, and the characteristic of the electric signal supplied by the equipment is obtained. The electric signal detection module may be a hardware or software module for detecting a voltage value and/or a current value, or a hardware or software module for detecting elements such as a waveform and a frequency of an alternating current.
In addition, the traditional intelligent gateway has the functions of network protocol conversion, routing and the like, and does not have the capabilities of identifying events of the internet of things and generating event messages of the internet of things.
The network connection service provided by the intelligent gateway can be a certain area, and the devices in the area can all obtain the electric energy through the intelligent gateway in the embodiment of the invention. The intelligent gateway can conveniently detect the electric signal characteristics of the devices, thereby identifying the state and/or action of each device, further determining the corresponding event of the internet of things and reporting. By the mode, the access management of the Internet of things can be simultaneously carried out on a plurality of devices. In order to distinguish each device and each power supply line, corresponding device numbers can be respectively given to each power supply line in an intelligent gateway, and when an event message of the internet of things is generated, the device numbers are packaged into the message together, so that the cloud can distinguish the event of the internet of things of each device. The device numbers can be preset in the intelligent gateway, and the corresponding device numbers can be set according to different power supply lines accessed by the devices. The functions of identifying and analyzing the detected electric signal characteristics to determine the state and/or action of the equipment, performing message encapsulation on the event of the internet of things and the like can be realized through an embedded CPU of the intelligent gateway, and the edge computing capability of the intelligent gateway on the event of the internet of things is realized by adding a corresponding processing program into the CPU.
Fig. 2 is a schematic diagram of an exemplary structure of an intelligent gateway according to an embodiment of the present invention. In an intelligent gateway, an AC/DC (alternating current/direct current) power supply module is connected to an external power supply and converts it into three-phase alternating current required by the device and direct current required by an embedded CPU. The lead at the output end of the AC/DC power supply module is divided into a plurality of branches which are used as power supply lines for supplying electric energy to equipment, the lines are connected with socket interfaces which are plugged with plugs of the equipment, and meanwhile, each power supply line is also provided with a relay for on-off control. Each power supply line is connected with an electric signal detection module, the electric signal detection module detects the characteristics of electric signals on the power supply lines, detection data are provided for an embedded CPU through a communication interface between the embedded CPU and the embedded CPU, the embedded CPU executes the edge calculation function of the embedded CPU, generates event messages of the Internet of things and reports the event messages to the cloud. In the figure, the line marked "L" represents the live line, "N" represents the neutral line, and "E" represents the ground line, and the socket interface is only schematically shown on the line connected to the live line in order to simplify the representation of the socket interface.
In addition, the above-mentioned process of identifying the event of the internet of things of the device through the detection of the power supply line is also realized by devices other than the intelligent gateway. For example, the functions can be configured on the intelligent patch board, the identification of the internet of things equipment of the equipment is realized and the internet of things equipment is packaged into an internet of things event message by detecting the characteristics of electric signals of a power supply line corresponding to the equipment on the patch board, the communication is carried out with an intelligent gateway through a wireless local area network, and the internet of things event message is sent to the cloud end through the intelligent gateway. In such a manner, the original intelligent gateway only having the protocol conversion and routing functions can still be adopted by the intelligent gateway, and the internet of things capability is realized by the intelligent patch board, so that the existing equipment does not need to be changed in the manner.
The electrical signal characteristics may include: one or any more of waveform characteristics, frequency characteristics, amplitude characteristics of the voltage and/or current on the power supply line. The states and/or actions of the devices described above may include: one or any more of start-stop of the equipment, processing actions performed by the equipment, operating conditions of the equipment, equipment faults, data statistics of equipment actions and/or conditions.
Specifically, as an example, for a device including a motor, such as a sewing machine, a lathe, a drilling machine, and the like, when the motor is turned on or off or performs some specific action, the current value on the power supply line may exhibit a certain variation characteristic. Taking the judgment of the start and stop of the motor as an example: the current value on the power supply line may be detected at preset time intervals and compared with a preset current threshold. And if the current values are adjacent twice, the current value is lower than the current threshold value for the first time and higher than the current threshold value for the second time, the equipment is determined to be switched into the motor starting state. And if the current values are adjacent twice, the current value is higher than the current threshold value for the first time and lower than the current threshold value for the second time, the equipment is determined to be switched into the motor stop state.
The specific operation performed by some devices can be judged by the starting action of the motor. For example, the typical operation of a sewing machine is to start and stop the motor once every sewing needle, the start and stop of the motor can be controlled by a program, and if the sewing machine is operated manually, the start and stop of the motor can also be controlled by stepping on a pedal by staff. Through the detection to the motor opens and stops, can discern the sewing machine and make up the thing networking incident of a stitch, in addition, can also further calculate every time of making a stitch duration and the time interval information between two adjacent needles etc. these information all can report to the high in the clouds with the form of thing networking incident.
In addition, the detection module for the electric signals on the power supply line and the power interface may also be disposed at the device side, for example, an electric signal detection unit may be added to the power interface of the device, and then the electric signal detection unit may send the electric signal to the intelligent gateway through bluetooth or a wireless lan. Besides, artificial intelligence equipment for detecting the states of other aspects of the equipment can be added on one side of the equipment to assist in judging the running state of the equipment. For example, the audio emitted by the device may be detected and analyzed to determine the state of the device, such as whether the device is in an operating or stopped state, whether the device is in a high-speed operation or a low-speed operation, and the like. The intelligent gateway can be configured with a user interaction interface, a user can access the intelligent gateway through equipment such as a mobile phone or a computer and the like, check the state and the running log of each equipment, and when the equipment is judged to be abnormal, prompt or alarm can be sent to the user through the user interface.
According to the processing technology of the event of the Internet of things, disclosed by the embodiment of the invention, the action and/or the state of the equipment are/is identified by detecting the characteristics of the electric signal on the power supply circuit of the equipment, and the event of the Internet of things is generated and reported, so that a module with the capability of the Internet of things does not need to be configured on the equipment, the equipment does not need to be changed, and the communication between the equipment and the Internet of things can be realized at a lower cost. Furthermore, the intelligent gateway can be combined with the intelligent gateway, an interface for supplying power to the equipment is arranged on the intelligent gateway, electric signal detection and generation of event messages of the Internet of things are carried out, and therefore the equipment is helped to realize connection of the Internet of things through the edge computing capacity of the intelligent gateway.

In particular, the detected electrical signal characteristics may include: one or any more of waveform characteristics, frequency characteristics, amplitude characteristics of the voltage and/or current on the power supply line.

Since the device, when performing a specific action or a change of state, may cause fluctuations in the electrical energy used, it may also be fed back to the supply line. In particular, the state and/or the action of the following devices can be identified from the electrical signal characteristics: one or any more of start-stop of the equipment, processing actions performed by the equipment, operating conditions of the equipment, equipment faults, data statistics of equipment actions and/or conditions.
S103: and generating an event message of the Internet of things according to the state and/or the action of the equipment, and reporting the event message to the cloud. The state and/or the action of the equipment can be used as an event of the internet of things, such as starting and stopping of a motor. In addition, specific operations executed by the equipment can be judged according to the state and/or the action of the equipment and specific application environments, for example, the starting and stopping action of a sewing machine corresponds to the operation of sewing a needle, and each time a drill bit of the drilling equipment completes a feeding action corresponds to one drilling operation, the operations can also be used as events of the internet of things. In addition, for some statistics of device actions or operations, the statistics can also be reported as events of the internet of things, for example, the number of times of motor rotation per minute and the like.

The electric signal detection module can be realized by a hardware circuit or by a mode of combining software and hardware, the process of further determining the state and/or action of the equipment according to the detected electric signal characteristics can also be realized by the original CPU of the intelligent gateway, the state and/or action of the equipment can be identified by adding a corresponding processing program in the system of the intelligent gateway, and the processing mode utilizes the edge capability of the intelligent gateway.

Specifically, the current value on the power supply line may be detected at preset time intervals and compared with a preset current threshold. If the current values of the two adjacent times are lower than the current threshold value for the previous time and higher than the current threshold value for the subsequent time, determining that the equipment is switched to a motor starting state; and/or if the current value is higher than the current threshold value for the first time and lower than the current threshold value for the second time, the equipment is determined to be switched into the motor stop state.
In addition, after some actions of the motor are detected, the processing action executed by the equipment can be determined according to the duration and/or switching mode of the starting state and/or the stopping state of the motor, and the starting and stopping of the motor at one time corresponds to the sewing action of one needle by taking the sewing machine as an example. Then, after the processing action is recognized, the processing action can be packaged into an event message of the internet of things and reported to the cloud.
