Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a schematic structural diagram of an embodiment of an abnormality detection system for an electrical apparatus according to the present invention, and as shown in fig. 1, the abnormality detection system for an electrical apparatus according to the present embodiment includes an abnormality detection device 10 and a monitoring terminal 11. The abnormality detection device 10 includes a controller 101, an abnormality detection module 102, and a communication module 103; the abnormality detection module 102 includes a line detection unit 1021 and a failure detection unit 1022. The output terminal of the fault detection unit 1022, the input terminal of the communication module 103, and the output terminal of the power supply of the electrical apparatus are respectively connected to the controller 101. The input end of the line detection unit 1021 is connected with the output end of the power supply; an output terminal of the line detection unit 1021 is connected to the controller 101. The communication module 103 includes a General Packet Radio Service (GPRS) module and/or a Wireless-Fidelity (WI-FI) module. The controller 101 in the present embodiment is preferably an air conditioner controller 101 and/or a refrigerator controller 101.
In one implementation, the line detecting unit 1021 is used for collecting and sending a power supply signal of a power supply to the controller 101. For example, the line detection unit 1021 includes a current sampling component and a current conversion component; the output end of the power supply and the current conversion assembly are respectively connected with the current sampling assembly; the current conversion assembly is connected to the controller 101. The input end of the line detection unit 1021 is connected with the output end of the power supply; the output of line detecting element 1021 links to each other with controller 101, and like this, line detecting element 1021 forms parallel circuit with controller 101, is in normal power supply state at electrical equipment, no matter the air conditioner is running state or standby state, current sampling subassembly all can detect there is the electric current to flow through, and at this moment, current sampling subassembly gathers power supply's current signal, and the current conversion subassembly is used for converting the current signal of the power supply who current sampling subassembly gathered into power supply's voltage signal as power supply's power supply signal. Wherein the current sampling assembly comprises a current sensor.
In this embodiment, the fault detection unit 1022 is configured to collect and send operation information of the electrical apparatus to the controller 101. For example, various sensors may be disposed at corresponding monitoring positions of the electrical equipment, such as a pressure sensor, so that the fault detection unit 1022 may acquire the operation information of the electrical equipment and send the operation information of the electrical equipment to the controller 101.
In a specific implementation process, the controller 101 can send an apparatus operation abnormal signal to the monitoring terminal 11 through the communication module 103, and the monitoring terminal 11 can output the apparatus operation abnormal signal, so that a technician can know an abnormal position of the electrical apparatus according to the apparatus operation abnormal signal.
In this embodiment, because when the line or the power supply is abnormal, the controller 101 cannot be continuously powered and the electrical equipment cannot normally operate, in this embodiment, the controller 101 may monitor whether the line detection unit 1021 performs signal transmission in real time, and if the controller 101 does not receive the power supply signal sent by the line detection unit 1021, it indicates that the line or the power supply cannot normally provide power for the controller 101, but because the rectifier bridge filter capacitor and some control circuit voltage conversion capacitors exist inside the controller 101, the controller 101 cannot immediately stop working at the moment of power failure of the power supply line, the controller 101 may send a first signal of power supply abnormality to the monitoring terminal 11 through the communication module 103 during the discharge time of the capacitors, so that the monitoring terminal 11 outputs the first signal of power supply abnormality, and a technician can output the first signal of power supply abnormality according to the first signal of power supply abnormality, the reason for knowing that the electrical equipment cannot normally operate is caused by the abnormality of the line or the power supply.
It should be noted that, in this embodiment, the device operation abnormal signal and the first signal of the power supply abnormality may be output by the monitoring terminal 11 alone, or may be output at the same time, and this embodiment is not limited specifically.
In practical application, although the power supply can normally supply power to the controller 101, the controller 101 may have an abnormality, which may cause the power management circuit of the controller 101 to be unable to obtain power or unable to supply power to the outside, and at this time, the electrical equipment may still be unable to normally operate, therefore, in this embodiment, the monitoring terminal 11 may monitor whether the communication between the monitoring terminal 11 and the communication module 103 is normal in real time, and if it is detected that the communication with the communication module 103 is disconnected, output a power supply abnormal signal of the controller 101, so that a technician can know that the reason why the electrical equipment cannot normally operate is caused by the abnormality of the controller 101 according to the power supply abnormal signal of the controller 101.
According to the abnormity detection system of the electrical equipment, when the electrical equipment is abnormal, a technician can quickly locate a problem point by analyzing and processing the problem by methods such as continuous troubleshooting, multiple point-by-point test, gradual analysis, layer-by-layer progressive and the like, meanwhile, live test is avoided, and the personal safety of the technician is guaranteed; and avoids carrying a large amount of test equipment.
On one hand, in the abnormality detection system for electrical equipment of this embodiment, when the controller 101 is not abnormal, the controller 101 may detect the abnormality of the electrical equipment itself according to the operation information of the electrical equipment sent by the fault detection unit 1022, may also detect the abnormality of the line or the power supply according to the power supply signal of the power supply sent by the line detection unit 1021, and report the apparatus operation abnormality signal and/or the first signal of the power supply abnormality to the monitoring terminal 11 through the communication module 103. On the other hand, in the case where an abnormality occurs in the controller 101, the monitoring terminal 11 may output a power supply abnormality signal of the controller 101 upon detecting that the communication with the communication module 103 is disconnected. By adopting the technical scheme of the invention, the problem points can be safely and quickly positioned, the problem processing time is shortened, and the maintenance efficiency of the electrical equipment is improved.
Further, in the above embodiment, the controller 101 is further configured to detect whether a power supply value corresponding to the power supply signal exceeds a rated working value of the electrical apparatus if the power supply signal is received, and send a second signal indicating that power supply is abnormal to the monitoring terminal 11 through the communication module 103 when the power supply value exceeds the rated working value of the electrical apparatus, so as to prevent the circuit from generating an electric leakage and an electricity stealing phenomenon.
In a specific implementation process, in order to improve the accuracy of the anomaly detection, in the anomaly detection system of the electrical equipment in this embodiment, the monitoring terminal 11 further needs to start timing when the monitoring terminal 11 is disconnected from the communication module 103, so as to obtain a timing duration when the monitoring terminal 11 is disconnected from the communication module 103, compare the timing duration with a preset duration, and if the obtained timing duration reaches the preset duration, it indicates that there is an anomaly in the controller 101 itself, at this time, the monitoring terminal 11 may output an abnormal power supply signal of the controller 101, thereby preventing false triggering of the abnormal power supply signal of the controller 101.
Further, in the anomaly detection system for electrical equipment in this embodiment, the monitoring terminal 11 needs to try to establish communication with the communication module 103 again according to a preset period after the monitoring terminal 11 is disconnected from the communication module 103, and after each attempt fails, 1 is added to the original failure frequency, so as to count the failure frequency of trying to connect with the communication module 103, compare the counted failure frequency with the preset frequency, and output a power supply anomaly signal of the controller 101 if the counted failure frequency reaches the preset frequency, thereby preventing false triggering of the power supply anomaly signal of the controller 101.
In practical applications, the disconnection of the communication between the monitoring terminal 11 and the communication module 103 may be caused by poor network signals, so that the probability of false triggering of the abnormal power supply signal of the controller 101 is increased.
In this embodiment, a local area network may be established, so that the electrical device and another device with the communication module 103 are located in the same local area network, and thus, data interaction can be performed between the electrical device and another device with the communication module 103.
In this embodiment, the electrical device to be detected is defined as a, and another device with the communication module 103 is defined as B. In a normal state, the communication between the electrical device a and the electrical device B is disconnected, and the communication between the monitoring terminal 11 and the electrical device B is disconnected. When the monitoring terminal 11 detects that the monitoring terminal 11 is disconnected from the communication module 103, the monitoring terminal 11 can send a request for establishing connection with the device B to the server, and after the device B is connected with the monitoring terminal 11, the device B can be controlled to access the local area network, so that the electrical device a and the device B are in the same local area network. At this time, the device B may obtain the relevant signal from the electrical device a and upload the relevant signal to the monitoring terminal 11. In this embodiment, if the controller 101 of the electrical apparatus a is abnormal, although the electrical apparatus a and the apparatus B are in the same local area network, the signal stability between the two is good, the apparatus B cannot acquire the relevant signal from the electrical apparatus a, at this time, the apparatus B cannot upload the relevant signal to the monitoring terminal 11, and at this time, it can more accurately determine that the controller 101 is abnormal, that is, an abnormal signal of power supply to the controller 101 can be output.
In this embodiment, when the device B detects whether the control in the electrical device a is abnormal, the timing duration and the number of connection attempt failures may be counted, and then the power supply abnormal signal of the controller 101 may be further output. The communication performance of the wireless communication module 103 in the device B is preferably greater than that of the communication module 103 in the electrical device a. Since the communication function of the mobile phone is usually better, in order to save resources, the device B in this embodiment is preferably a waste mobile phone, so as to recycle the waste mobile phone.
