Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0036] The embodiments of the present application provide a servo motor operation state monitoring method, which realizes comprehensive monitoring of the operation state of a servo motor by detecting real-time measured operation temperature values, real-time measured environment temperature values, real-time measured voiceprint values, real-time measured voltage values and real-time measured current values of the servo motor through an infrared temperature sensor, an environment temperature sensor, a voiceprint sensor, a voltage sensor and a current sensor connected with a control system, thereby achieving the effect of timely discovering faults existing in the servo motor.

[0037] According to the embodiments of the present application, a servo motor operation state monitoring method embodiment is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] In the present embodiment, a servo motor operation state monitoring method is provided, which is used in a control system 114 as shown in Fig. 1. The control system 114 is connected with an infrared temperature sensor 12, an environment temperature sensor 13, a voiceprint sensor 14, a voltage sensor 15 and a current sensor 16 respectively. The servo motor is used to rotate a corresponding photovoltaic support. The control system 114 and the above-mentioned infrared temperature sensor 12, environment temperature sensor 13, voiceprint sensor 14, voltage sensor 15 and current sensor 16 can be connected by wireless connection or wired connection. Optionally, the current sensor 16 can be a Hall current monitoring sensor.

[0039] Fig. 2 is a flow chart of a method for monitoring the operating state of a servo motor according to an embodiment of the present application. As shown in Fig. 2, the flow includes the following steps:

[0040] At step S201, when the servo motor is operating, the measured operating temperature value of the servo motor sent by the infrared temperature sensor, the measured ambient temperature value sent by the ambient temperature sensor, the voiceprint measured value sent by the voiceprint sensor, the voltage measured value sent by the voltage sensor, and the current measured value sent by the current sensor are received.

[0041] Specifically, the infrared temperature sensor 12 can be used to monitor the operating temperature of the servo motor in real time and obtain the corresponding measured operating temperature value of the servo motor, and then send the obtained measured operating temperature value of the servo motor to the control system 114.

[0042] Optionally, the ambient temperature sensor 13 can be used to monitor the ambient temperature of the servo motor in real time and obtain the corresponding measured ambient temperature value, and then send the obtained measured ambient temperature value to the control system 114.

[0043] Optionally, the voiceprint sensor 14 can be used to monitor the rotating sound of the corresponding photovoltaic support of the servo motor in real time and obtain the corresponding voiceprint measured value, and then send the obtained voiceprint measured value to the control system 114.

[0044] Optionally, the voltage sensor 15 can be used to monitor the power supply voltage of the servo motor in real time and obtain the corresponding voltage measured value, and then send the obtained voltage measured value to the control system 114.

[0045] Optionally, the current sensor 16 can be used to monitor the power supply current of the servo motor in real time and obtain the corresponding current measured value, and then send the obtained current measured value to the control system 114.

[0046] At step S202, based on the measured operating temperature value of the servo motor, the measured ambient temperature value, the voiceprint measured value, the voltage measured value, and the current measured value, the operating state of the servo motor is monitored respectively to obtain the operating state monitoring result of the servo motor.

[0047] Specifically, after the control system 114 receives the measurement values sent by each sensor, the operating state of the servo motor can be monitored according to the measurement values sent by each sensor respectively, realizing comprehensive monitoring of the operating state of the servo motor, and then through the above monitoring, the existing faults of the servo motor can be found in time.

[0048] The servo motor operation state monitoring method provided in the embodiment can detect the corresponding servo motor measured operation temperature value, measured environment temperature value, voiceprint measured value, voltage measured value and current measured value in real time through the infrared temperature sensor, environment temperature sensor, voiceprint sensor, voltage sensor and current sensor connected with the control system, and then the operation state of the servo motor can be comprehensively monitored through these measured values. Therefore, by implementing the present application, the existing faults of the servo motor can be found in time.

[0049] In the embodiment, a servo motor operation state monitoring method is provided for a control system 114 as shown in FIG. 1, which is connected with an infrared temperature sensor 12, an environment temperature sensor 13, a voiceprint sensor 14, a voltage sensor 15, a current sensor 16 and a solar irradiance measurement sensor 17 respectively. The servo motor is used to rotate a corresponding photovoltaic support.

[0050] FIG. 3 is a flowchart of the servo motor operation state monitoring method according to the embodiment of the present application. As shown in FIG. 3, the flow includes the following steps:

[0051] Step S301, receiving the rotation angle sent by the solar irradiance measurement sensor.

[0052] The solar irradiance measurement sensor 17 is a sensor for measuring light intensity, which can convert the solar irradiance into an electrical signal for measurement, and is usually composed of a photoelectric sensor and a signal processing device.

[0053] Specifically, the solar irradiance measured by the solar irradiance measurement sensor 17 can be used for power generation of the photovoltaic module in the corresponding photovoltaic support of the servo motor.

[0054] Optionally, the inclination angle of the photovoltaic module can be determined according to the power generation of the photovoltaic module.

[0055] Optionally, the inclination of the photovoltaic module is formed by the rotation of the photovoltaic support by the servo motor.

[0056] Therefore, in order to ensure the power generation of the photovoltaic module, the solar irradiance measurement sensor 17 can directly calculate the rotation angle of the corresponding servo motor according to the measured solar irradiance.

[0057] Step S302, controlling the operation of the servo motor based on the rotation angle.

[0058] Specifically, according to the description of step S301 above, the control system 114 can control the operation of the servo motor according to the rotation angle received from the solar irradiance measurement sensor 17.

[0059] Step S303, when the servo motor is running, receiving the measured running temperature value of the servo motor sent by the infrared temperature sensor, the measured ambient temperature value sent by the ambient temperature sensor, the voiceprint measured value sent by the voiceprint sensor, the voltage measured value sent by the voltage sensor and the current measured value sent by the current sensor. For details, please refer to step S201 of the embodiment shown in FIG. 2, which will not be described here.

[0060] Step S304, based on the measured running temperature value of the servo motor, the measured ambient temperature value, the voiceprint measured value, the voltage measured value and the current measured value, the running state of the servo motor is monitored respectively, and the running state monitoring result of the servo motor is obtained.

[0061] Specifically, the above step S304 includes:

[0062] Step S3041, based on the measured running temperature value of the servo motor and the measured ambient temperature value, judging whether the temperature of the servo motor meets the normal working condition.

[0063] Specifically, combined with the measured running temperature value and the measured ambient temperature value actually measured, it can be judged whether the temperature of the servo motor meets the normal working condition.

[0064] In some optional embodiments, the above step S3041 includes:

[0065] Step a1, obtaining the initial temperature value of the servo motor.

[0066] Step a2, determining the temperature difference value of the measured running temperature value of the servo motor and the measured ambient temperature value.

[0067] Step a3, based on the measured running temperature value of the servo motor and the initial temperature value of the servo motor, determining the temperature change difference value of the servo motor.

[0068] Step a4, based on the temperature difference value and the temperature change difference value of the servo motor, judging whether the temperature of the servo motor meets the normal working condition.

[0069] Wherein, the initial temperature value of the servo motor is the running temperature of the servo motor in the normal working state measured by the infrared temperature sensor 12 in advance.

[0070] Specifically, the temperature difference value of the measured running temperature value of the servo motor and the measured ambient temperature value is calculated.

[0071] Optionally, combined with the measured running temperature value of the servo motor in the normal working state and the initial temperature value of the servo motor actually measured in the current working state, the temperature change difference value of the servo motor can be calculated.

[0072] Finally, the temperature difference and the temperature change difference of the servo motor are combined to determine whether the temperature of the servo motor meets the normal working condition.

[0073] In some optional embodiments, the step a4 comprises:

[0074] In step a41, it is determined whether the temperature difference meets a preset first change condition.

[0075] In step a42, it is determined whether the temperature change difference of the servo motor meets a preset second change condition.

[0076] In step a43, when the temperature difference does not meet the preset first change condition and the temperature change difference of the servo motor does not meet the preset second change condition, it is determined that the temperature of the servo motor does not meet the normal working condition.

[0077] The preset first change condition and the preset second change condition are used to indicate whether the change of the operating temperature of the servo motor affects the operation of the servo motor.

[0078] Specifically, if the temperature difference does not meet the preset first change condition and the temperature change difference of the servo motor does not meet the preset second change condition, it indicates that the operating temperature of the servo motor is significantly high, and there may be an electrical short circuit fault of the servo motor or a problem of long-term overloading of the servo motor, which may cause the servo motor or the electrical circuit to burn out.

[0079] Therefore, when the temperature difference does not meet the preset first change condition and the temperature change difference of the servo motor does not meet the preset second change condition, it can be determined that the temperature of the servo motor does not meet the normal working condition.

[0080] In step S3042, the measured voiceprint value is compared with the preset voiceprint value.

[0081] Specifically, the preset voiceprint value is the rotating sound of the servo motor in the normal working state of the photovoltaic support, which is measured in advance by the voiceprint sensor 14.

[0082] In step S3043, the measured voltage value is compared with the preset voltage value, and the measured current value is compared with the preset current value.

[0083] Specifically, the preset voltage value is the power supply voltage of the servo motor in the normal working state, which is measured in advance by the voltage sensor 15; and the preset current value is the power supply current of the servo motor in the normal working state, which is measured in advance by the current sensor 16.

[0084] Step S3044, when the temperature of the servo motor does not meet the normal working condition or the voiceprint measured value is greater than the preset voiceprint value or the voltage measured value is greater than the preset voltage value or the current measured value is greater than the preset current value, it is determined that the running state monitoring result is that the servo motor runs abnormally.

[0085] Specifically, if the voiceprint measured value is greater than the preset voiceprint value, it indicates that the rotation sound of the photovoltaic support corresponding to the servo motor is too large, at this time, there may be problems such as abnormal rotation components of the photovoltaic support, deformation, jamming, rust, etc. of the support supporting components.

[0086] Alternatively, if the voltage measured value is greater than the preset voltage value or the current measured value is greater than the preset current value, it indicates that the voltage measured value and the current measured value are significantly large, that is, the working load of the servo motor is significantly large, at this time, the servo motor works over load, and there may be problems such as jamming of the support supporting components.

[0087] Therefore, in combination with the description of step S3041, when one or more of the following conditions exist, it can be determined that the running state monitoring result is that the servo motor runs abnormally:

[0088] (1) the temperature of the servo motor does not meet the normal working condition;

[0089] (2) the voiceprint measured value is greater than the preset voiceprint value;

[0090] (3) the voltage measured value is greater than the preset voltage value;

[0091] (4) the current measured value is greater than the preset current value.

[0092] The servo motor running state monitoring method provided in the embodiment can control the operation of the servo motor through the solar irradiance measurement sensor connected with the control system. Secondly, through the infrared temperature sensor, the environmental temperature sensor, the voiceprint sensor, the voltage sensor and the current sensor connected with the control system, the corresponding servo motor measured running temperature value, measured environmental temperature value, voiceprint measured value, voltage measured value and current measured value can be detected in real time, and then the running state of the servo motor is judged through the servo motor measured running temperature value, measured environmental temperature value, voiceprint measured value, voltage measured value and current measured value. As long as one of them does not meet the condition, it can be determined that the running state monitoring result is that the servo motor runs abnormally, the running state of the servo motor is comprehensively monitored, and the existing faults of the servo motor can be found in time.
