Detailed Description
The applicant found that in the prior art, the servo motor 701 in the ac servo system is an execution unit of the system, and the operating state of the servo motor 701 determines the performance of the whole system. In general, the servo system should require real-time monitoring of important parameters such as the operating temperature, current and voltage, and vibration and rotational speed of the servo motor 701. However, the servo system of the prior art generally controls the servo motor 701 through a driver 702, and the servo motor 701 and the driver 702 are connected through a driving wire, a transmission wire for coding signals, and a braking wire 703 of the servo motor 701. Therefore, there is no additional channel in the servo system to transmit the monitoring data of the servo motor 701. Since the driver 702 cannot receive real-time monitoring data, the driver 702 cannot adjust the servo motor 701 according to the detection result of the monitoring data by the monitoring data. Therefore, in the prior art, in order to enable the servo system to have the functions of real-time monitoring and corresponding adjustment, an acquisition module 704 (the acquisition module 704 generally refers to sensors of temperature, current, voltage, acceleration, etc.) is generally installed on one side of the servo motor 701 for acquiring various monitoring data of the servo motor 701, and the monitoring data is processed in a processor 717 arranged on the servo motor 701 and then transmitted to a PC end or a mobile end in a wired or wireless manner. And then, special software on the PC terminal or the mobile terminal detects the monitoring data to generate a detection result, and a corresponding response is made according to the detection result. However, no matter the wired or wireless method is adopted for signal transmission, the matched communication module is added correspondingly, and no matter the wired or wireless method is adopted for signal transmission, the cost is increased. In order to solve the above problem, the present application provides a method for processing monitoring data of the servo motor 701, and first, real-time operation state data (such as current, voltage, rotation speed, temperature, and the like) of the servo motor 701 is acquired. Since the operation state data collected by the collection module 704 is an analog quantity, the operation state data needs to be converted into a digital quantity, i.e., monitoring data information. After the servo motor 701 and the driver 702 are connected by the brake line 703, carrier transmission is performed on the brake line 703 to transmit real-time monitoring data information of the servo motor 701 to the driver 702, so that the driver 702 detects the real-time monitoring data information. By adopting the processing method, the signal transmission can be carried out under the condition that other communication modules and signal transmission lines are not added (actually, the signal transmission lines are simplified through carriers), and the cost of the prior art is greatly reduced.
In order to make the technical scheme and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
for simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Numerous details of the embodiments are set forth to provide an understanding of the principles of the invention. It will be apparent, however, that the invention may be practiced without these specific details. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "including" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". In view of the language convention of chinese, the following description, when it does not specifically state the number of a component, means that the component may be one or more, or may be understood as at least one.
Fig. 1 is an exemplary flowchart of a processing method of monitoring data of a servo motor 701 according to an embodiment of the present invention. As shown in fig. 1, in an alternative embodiment, the present application provides a method for processing monitoring data of a servo motor 701, including:
Step 102, collecting operation state data of the servo motor 701, wherein the operation state data is analog quantity.
In this step, data is collected on the temperature, current, voltage, even acceleration and vibration conditions of the servo motor 701, and the collected data is the motion state data. The motion state data is a physical analog quantity collected by a sensor (such as a temperature sensor, a current sensor, an accelerometer, and the like).
And 104, converting the running state data into monitoring data information, wherein the monitoring data information is a digital quantity.
in this step, the main purpose is to convert the collected operating state data into digital quantities. Since the subsequent carrier operation can be performed only by converting the operation state data into digital quantity (i.e. the monitoring data information). In addition, the monitoring data information and the operation state data are the same content, and only digital-to-analog conversion is carried out.
Step 106, modulating the monitoring data information carrier and loading the modulated monitoring data information carrier on a brake line 703 of the servo motor 701, wherein two ends of the brake line 703 are respectively connected with the servo motor 701 and the driver 702.
in this step, the monitoring data information is modulated and then a carrier is carried on the brake line 703, and a signal transmission line of the monitoring data information can be omitted in the carrier process. Meanwhile, the servo system does not need to be additionally provided with communication modules like WIFI, Bluetooth and the like, and the manufacturing cost is greatly reduced. In addition, the present embodiment is different from the prior art in the technical architecture, specifically, the prior art transmits the monitoring data information to the PC or the mobile terminal in a wired or wireless manner. However, in the present application, data is transmitted to the driver 702, which means that the conventional technology cannot adopt a carrier technology, because neither the PC terminal nor the mobile terminal can receive a carrier signal by using the method of the present application, specifically, the conventional PC terminal or the mobile terminal adopts signal transmission without power transmission with the servo motor 701, and only when the power transmission and the signal transmission exist at the same time, the carrier technology is based on.
step 108, sending the monitoring data to the driver 702 through the brake line 703, so that the driver 702 receives the monitoring data and then detects the monitoring data.
In this step, the monitoring data of the servo motor 701 is transmitted to the driver 702 by the brake line 703, and the driver 702 receives and processes the monitoring data information. Since the main body of processing the monitoring data information is converted into the driver 702 by a conventional PC side or a mobile side, the inside of the driver 702 can be directly copied to the processing program. The problem that the PC end or the mobile end uses special software is solved, because the special software needs special operators to operate on one hand, and on the other hand, the development cost of the human-computer interaction function of the special software is high. The technical architecture of the application can save operators and is actively controlled by a program. The training of operators is omitted, the development of human-computer interaction functions is omitted, and the manufacturing cost is reduced.
In another optional embodiment, the converting the operation state data into the monitoring data information includes:
Step 202, filtering the operation state data.
In this step, the present application is different from the conventional digital-to-analog conversion (the digital-to-analog conversion refers to converting an analog quantity and a digital quantity). Since the monitoring data information is transmitted in the form of a carrier wave. And before the transmission of the monitoring data information, filtering the monitoring data information, eliminating interference signals in the monitoring data information, and providing a precondition for the subsequent data extraction and digital-to-analog conversion.
And 204, extracting monitoring data from the filtered running state data, wherein the monitoring data is analog quantity.
In this step, the monitoring data is extracted from the operation state data acquired after filtering, and because there is much interference in the operation state data, filtering the operation state data can greatly shield the interference signals doped in the operation state data. After filtering, specific data such as the temperature, the rotating speed, the current, the voltage and the like of the servo motor 701 can be extracted from the running state data, the data is the monitoring data, and the monitoring data is still analog quantity at the moment.
step 206, converting the monitoring data into the monitoring data information.
Finally, the monitoring data information is converted into digital quantity by means of digital-to-analog conversion, because only after the conversion of the digital quantity is completed can the monitoring data information be further transmitted to the driver 702 in the form of carrier wave. It should be noted that, in the technical framework of the present application, it is actually a closed technical environment, and the information transmission only occurs between the driver 702 and the servo motor 701, and the driver 702 and the servo motor 701 are connected by a wire (i.e. the brake wire 703), so that the safety of the system can be guaranteed to the greatest extent. However, under the conventional technical system, data is first transmitted to the PC side or the mobile side. The PC side or the mobile side may receive other data in many cases, so insecurity in the servo system may be caused (because the PC side and the mobile side are development environments). In addition, the brake line 703 is a hardware connection line which is necessary in the prior art, so that additional hardware cost is not increased, and a signal transmission line between the driver 702 and the servo motor 701 is eliminated through a carrier wave (signal transmission) of the brake line 703, and the cost is saved.
In another optional embodiment, after converting the monitoring data into the monitoring data information, the method further comprises:
step 302, receiving a demand instruction of the driver 702 for the monitoring data information;
In this step, the information interaction between the driver 702 and the servo motor 701 is mainly explained. Specifically, the driver 702 first sends a demand command, because the driver 702 is the active control end and the servo motor 701 is the controlled end under normal conditions. The specific role of the demand instruction is to determine the type of monitoring data information that is specifically needed, because in practical applications, technical data such as the rotation speed, temperature, current, and voltage of the servo motor 701 may be acquired, but under specific working conditions, the driver 702 may actually need to transmit only two technical parameters, i.e., the rotation speed and the temperature. The driver 702 is required to first send one of the demand instructions.
and step 304, classifying the monitoring data information according to different data types according to the demand instruction.
In this step, the digitized monitoring data information is further classified. Such as sorting the information of the rotation speed, temperature, current and voltage in the monitoring data information. So as to further process different monitoring data information later. As described in step 302, the collected data is not equivalent to the information that the drive 702 actually needs to process. In short, the servo motor 701 generally does not transmit all the monitoring data information, because the technical solution of the present application generally employs a real-time transmission manner, if all the monitoring data information is transmitted simultaneously in real time, the information amount is too large, and this manner can reduce the pressure of data transmission and make the control of the servo motor 701 by the driver 702 more targeted.
And step 306, modulating the monitoring data information according to the classified monitoring data information and a communication protocol, and then loading the monitoring data information on a brake line.
In this step, the data of the monitoring data information is still very messy and numerous. It needs to be packed according to the communication protocol before it can be sent to the driver 702. Communication protocols and packaging are conventional in the art and will not be described in detail herein.
fig. 2 is an exemplary flowchart of a processing method of monitoring data of the servo motor 701 according to another embodiment of the present invention. As shown in fig. 2, in another alternative embodiment, the present application further provides another processing method for monitoring data of a servo motor 701, where the method includes:
Step 402, receiving monitoring data information sent through a brake line on a driver side, wherein two ends of the brake line 703 are respectively connected with the servo motor 701 and the driver 702.
The data interaction process on the driver 702 side is mainly set forth in this step. Specifically, the driver 702 first receives the monitoring data information transmitted through the brake line 703. The monitoring data information is a digital quantity transmitted by a carrier technology.
Step 404, demodulating the monitoring data information received via the brake line 703.
in this step, the monitoring data information transmitted from the brake line 703 is demodulated. And the demodulated monitoring data information becomes information data which can be identified. In the present application, since the carrier data received by the driver 702 is a modulated packet, the demodulation process is performed first.
And 406, generating a corresponding control instruction according to the demodulated monitoring data information.
In this step, the driver 702 detects the state of the servo motor 701 based on the monitoring data information. In actual detection, when a failure of the servo motor 701 is found, a failure alarm and a failure code are given. The fault alarm and fault code are the information that the driver 702 needs to obtain as the basis for generating the control instructions.
And step 408, controlling the driver 702 to adjust the control strategy of the servo motor 701 according to the control command.
In this step, the control command adjusts the servo motor 701 through the driver 702, specifically, the control strategy of the driver 702 for the servo motor 701 is changed. The control strategy specifically means that the driver 702 can change the rotation speed, current or voltage, etc. of the servo motor 701, so that the servo motor 701 generates changes in working parameters, and the monitoring data information is corrected.
In an optional implementation manner, the generating a corresponding control instruction according to the demodulated monitoring data information includes:
And 502, analyzing the demodulated monitoring data information through a communication protocol.
In this step, the monitoring data information is first analyzed, so that the modulated monitoring data information is converted into content recognizable by the driver 702 according to the communication protocol.
And 504, detecting the analyzed monitoring data information according to different data types to generate a detection result.
In this step, the monitoring data information may be analytically determined as specific monitoring data information according to different data types thereof, such as current, voltage or rotation speed of the servo motor 701, temperature, and the like. And detecting according to the specific monitoring data information and generating a detection result.
and step 506, generating a corresponding control instruction according to the detection result.
in this step, the control command is generated according to the result after the detection result is obtained. The driver 702 is preset with the control command for the servo motor 701 in different states. The control commands regulate the driver 702 to control the temperature, speed, and other motion of the servo motor 701.
in an optional embodiment, the receiving the monitoring data information sent by the braking line 703, wherein before the step of receiving the monitoring data information sent by the braking line on the driver side, the method further comprises:
Step 602, generating a demand instruction according to the preset.
under actual conditions, the driver 702 generally does not acquire all the acquisition states of the servo motor 701, and the specific reasons have been described above and are not described herein again. Then some of the monitored data information is obtained as a function of the preset as a driver 702. The monitoring data information that the driver 702 needs to obtain forms the demand instruction.
in step 604, the driver 702 sends the demand instruction to the servo motor 701, so that after receiving the demand instruction, the servo motor 701 sends the classified monitoring data information to the driver 702 according to the demand instruction.
In this step, after the servo motor 701 receives the demand instruction, the servo motor 701 may determine that the monitoring data information needs to be sent, so as to accept or reject the collected operation state data, and provide a basis and a foundation for the subsequent classification step.
basic principle and working process:
First, the operating state data of the servo motor 701 (the operating state data generally refers to the temperature, current, voltage, and rotation speed of the servo motor 701) is collected. The operation state data just collected is an analog parameter and can not be directly used for modulating a carrier wave, so the operation state data needs further digital-to-analog conversion. The monitoring data information is obtained after the operation state data are converted, and the operation state data are filtered before conversion. And shielding the interference signals in the operation state data, wherein the shielding of the interference signals also provides a basis for the subsequent modulation carrier transmission. At the moment, the monitoring data information is converted into digital quantity, and before the carrier wave is modulated, the monitoring data information is classified according to different data types. Because the collected signals are very complicated, all the monitoring data information does not need to be transmitted in real time in the actual process. The driver 702 will send a demand command according to the preset setting, so that the servo motor 701 obtains the information of the monitoring data after obtaining the information of the monitoring data. And modulating a carrier wave to the monitoring data information, transmitting a signal through a brake line 703 connected between the servo motor 701 and the driver 702, and detecting the monitoring data information after the driver 702 receives the monitoring data information.
