Description

Technical Field

[0001] This invention belongs to the field of remote intelligent motor technology, specifically relating to a remote intelligent temperature control motor with a data acquisition device and its data acquisition method. Background Technology

[0002] Remote intelligent temperature-controlled high-efficiency motors are currently a blank in China. However, with the development of intelligent and information network control technologies, remote motor control will soon become a reality. To better understand the actual operating status of the motor, it is necessary to know the actual voltage, current, power, and temperature rise of the motor under the current operating conditions. Once an abnormality occurs, an alarm signal should be issued to alert the owner, avoid motor failure due to abnormal conditions, ensure normal motor operation, and thus extend the motor's lifespan. However, there is currently a lack of relevant products and data collection methods on the market. Summary of the Invention

[0003] To solve the above problems, the present invention provides the following technical solution: a remote intelligent temperature control motor with a data acquisition device, comprising a motor and a junction box. The junction box is provided on one side of the motor. The junction box includes a junction box base and a junction box cover. The junction box base has a housing outlet hole on its side wall near the motor. A wiring board is provided in the junction box base. A sandwich layer is formed between the wiring board and the junction box base near the side wall of the motor. A current transformer is fixed in the sandwich layer. The data acquisition device is installed on the junction box cover.

[0004] Furthermore, the junction box cover is provided with a pull-up section, and a data acquisition device is fixedly installed in the inner cavity of the pull-up section. The data acquisition device is a PBCA integrated board.

[0005] Furthermore, a sandwich structure is formed between the terminal block and the junction box seat near the side wall of the motor by bolts.

[0006] Furthermore, the junction box is arranged perpendicularly to the horizontal plane on the side of the motor.

[0007] A method for collecting data from a remote intelligent temperature-controlled motor with a data acquisition device, characterized by comprising the following steps: S1. Collect various operating parameter data of each motor through current transformers and PCBA integrated devices, and generate historical records of each operating parameter in the cloud database. S2. Calculate the average values ​​of different types of operating parameters for all motors in the database; S3. Read the latest values ​​of each operating parameter data of each motor, and compare each type of parameter in each motor with its corresponding average value. If the difference between the latest value of a certain type of parameter in a certain motor and the corresponding average value is greater than or less than a preset threshold, an alarm count is triggered and step S4 is executed. Otherwise, the latest average value of the corresponding parameter type is calculated using the latest value of the parameter of a certain type, and step S3 is executed again. S4. Compare the value of the alarm counter corresponding to a certain type of parameter in a certain motor with the preset number of times. If the number of times the alarm counter corresponding to that type of parameter is greater than the preset number of times, then the type of parameter is considered abnormal and S5 is executed; otherwise, S6 is executed. S5. Analyze the abnormal parameter information and transmit it to the terminal; S6. Determine whether a certain type of parameter in a certain motor and its latest value are greater than or less than the average value corresponding to that type of parameter, and whether the difference between the latest value of that type of parameter and its latest value and the corresponding average value is greater than or less than a predetermined threshold. If yes, increment the alarm counter corresponding to the parameter by 1 and re-execute S4; otherwise, reset the alarm counter to zero and re-execute S3.

[0008] Furthermore, the interval between each reading of the latest value of each parameter in the automated equipment control system is 20 seconds.

[0009] Furthermore, the number of times preset in step S4 is 3.

[0010] The advantages of this invention are: 1. In this invention, a sandwich structure is formed between the terminal block and the junction box base near the motor sidewall for fixing the current transformer. The motor lead wires are directly passed through the transformer and fixed to the terminal block, which meets the requirement of convenient wiring, enhances aesthetics, and features a compact, reasonable, and highly practical structure. 2. In this invention, the original junction box cover is improved while maintaining the same length and width. It is raised to ensure electrical safety clearance and fix the PBCA integrated board to meet an IP55 or higher protection level, facilitating the connection of the sensor connectors. The junction box is positioned perpendicular to the horizontal plane on the side of the motor, slightly raised in the height direction, making the motor more aesthetically pleasing. 3. This invention provides a method for collecting data on a remote intelligent temperature-controlled motor with a data acquisition device. By comparing the value of a certain type of parameter in the motor with the total average value of the corresponding type of parameter of all motors in the current time period, the false alarm rate of equipment failure is greatly reduced.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0015] Example 1 A remote intelligent temperature-controlled motor with a data acquisition device includes a motor 1 and a junction box. The junction box is located on one side of the motor 1. The junction box includes a junction box base 2 and a junction box cover 9. The junction box base 2 has a housing outlet hole 3 on its side wall near the motor 1. A wiring board 4 is located inside the junction box base 2. A sandwich layer 5 is formed between the wiring board 4 and the side wall of the junction box base 2 near the motor 1, secured with bolts. A current transformer 6 is fixed in the sandwich layer 5. The current transformer 6 is an instrument that converts a large primary current into a small secondary current based on the principle of electromagnetic induction, converting disparate currents into a more uniform current for easier measurement, protection, and control. The motor 1 lead wire passes through the housing outlet hole 3 and the current transformer 6 and is then fixed to the wiring board 4. The junction box cover 9 has a pull-up section 7. A PBCA integrated board 8 is fixed in the inner cavity of the pull-up section 7. The board is a finished circuit board that can realize certain electrical functions. It is covered with various electronic components, including sensors and sensor connection terminals for collecting different operating parameters, such as the actual operating voltage U, current V, power P, and temperature rise Δt of motor 1. In addition to collecting relevant information, the PCBA integrated board can also control the operation of motor 1 through centralized calculation and output by MCU. The junction box is set perpendicular to the horizontal plane on the side of motor 1. When installing the acquisition device of motor 1, first install the junction box base 2, then fix the current transformer 6 and install the motor 1 terminal block 4, then connect the motor 1, and at the same time fix the PCBA integrated board 8 on the junction box cover 9. The junction box cover 9 is connected to the junction box base 2, and the PCBA integrated board 8 is connected to the motor 1 terminal block 4. Finally, lock the junction box cover 9 and the junction box base 2 to complete the assembly.

[0016] Example 2 A data acquisition method for a remote intelligent temperature-controlled motor with a data acquisition device. S1. Collect real-time voltage parameter data of six motors through current transformer 6 and PCBA integrated board 8 and send them to the cloud. Generate historical records of real-time voltage operating parameters of each motor in the cloud database. The first recorded data is, for example, V1, V2, V3, V4, V5, V6. S2. Calculate the average real-time voltage Vx of all motors in the database; that is, the sum of V1, V2, V3, V4, V5, and V6 divided by 6. S3. After a 20-second interval, read the latest real-time voltage value of each motor. For example, read the values ​​of V11, V22, V33, V44, V55, and V66. Compare the difference between V11, V22, V33, V44, V55, and V66 and the average value Vx. If any of the differences is greater than or less than a set threshold, which is adjusted according to different motors, in this embodiment it is set to 30V. If any of the differences between V11, V22, V33, V44, V55, and V66 and Vx is greater than or less than 30V, the remote alarm counter records an alarm for one of the corresponding motors and executes S4. Otherwise, calculate the new average voltage value Vx1 based on the latest real-time voltage value, which is the sum of V1, V2, V3, V4, V5, V6, V11, V22, V33, V44, V55, and V66 divided by 12, and re-execute S3. S4. Compare the alarm count value of the real-time voltage of each motor recorded by the alarm counter with the preset count value 3. If the alarm count value of one of the motors 1 is ≥3, the real-time voltage parameter is considered abnormal and an alarm is sent to the APP through the cloud. Otherwise, execute S5. S5. Determine whether the current real-time voltage and its latest value are greater than or less than their respective average values, and whether the difference between the latest value of the real-time voltage parameter and its corresponding average value is greater than or less than a predetermined threshold. That is, calculate the difference between V11, V22, V33, V44, V55, V66 and Vx respectively, and determine whether there is a motor whose difference is greater than or less than 30V. If so, after an interval of 20 seconds, read the latest real-time voltage of the motor and calculate whether the difference between the latest real-time voltage and its corresponding latest average voltage is also greater than or less than 30V. For example, assuming that the difference between V11 and its average value Vx is greater than or less than 30V, after an interval of 20 seconds, read the latest real-time voltage value V111 of the motor and determine whether the difference between V111 and its corresponding average value Vx is also greater than or less than 30V. If yes, increment the alarm counter by 1 and execute S4. If not, clear the alarm counter and re-execute S3. The advantage of this embodiment is that the motor malfunction is determined by whether the motor has three consecutive abnormal parameters. This avoids false alarms from the motor, which could lead to repair personnel arriving to find no damage and wasting repair costs.

[0017] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
