Description

Background

Most people wearing watches may be more concerned about water and shock resistance, and the concern about magnetic fields that are all around but cannot be seen is often not that high. The ferrous parts in the watch are sensitive to magnetic fields, in particular the hairspring. The magnetic field easily affects the elasticity of the balance spring and even deforms it. Serious can cause the hairspring to stick, stopping the watch from running. If a non-antimagnetic watch is placed in a magnetic field for a long time, the time accuracy of the watch is greatly influenced.

Currently, watches are antimagnetic before being shipped out of the factory. When the watch is subjected to antimagnetic testing, the running condition of the watch in a magnetic field needs to be observed manually, and the antimagnetic effect of the watch needs to be judged manually. The method for artificially judging the antimagnetic effect of the watch has low efficiency, and the judgment result is inaccurate due to the influence of human factors.

At present, the helmholtz coil or solenoid structure is mostly adopted for testing the antimagnetic performance of the watch. Since the helmholtz coil and solenoid structure can only generate magnetic field, it is necessary to use other devices, such as a meter calibrator and a demagnetizer, during the test of the watch. Because the used instruments are various, different devices need to be operated frequently in the test process, and sometimes even a plurality of people are needed to cooperate with the devices to achieve the purpose of antimagnetic test of the watch. In the process of testing the antimagnetic effect of the watch, the test efficiency is low due to the need of manual operation. The application provides a watch antimagnetic test method, manual operation equipment is not needed, automatic processing of watch antimagnetic tests is achieved, and watch antimagnetic test efficiency is improved. In addition, the method provided by the application does not need to manually evaluate the antimagnetic effect, and the accuracy of evaluation of the antimagnetic effect of the watch is improved.

Fig. 1 shows a schematic flow chart of a antimagnetic test system of a wristwatch provided by the present application, and referring to fig. 1, the system 100 is detailed as follows:

the system 100 includes: a sound sensor 20, a sound processing module 30 and a controller 10. The sound processing module 30 is connected to the sound sensor 20 and the controller 10, respectively. The sound sensor 20 is interfaced to the watch to be tested. The sound sensor 20 and the sound processing module 30 may constitute a sound recognition device. The sound sensor 20 may be connected to the controller 10.

The sound sensor 20 is configured to collect the first meter sound signal, the second meter sound signal, and the third meter sound signal, and send the first meter sound signal, the second meter sound signal, and the third meter sound signal to the sound processing module 30.

In the present embodiment, the sound sensor 20 is in contact with the watch bottom cover or the watch crown of the watch. The sound sensor 20 collects the sound emitted by the watch during operation by contact with the bottom cover of the watch.

In the present embodiment, the sound sensor 20 may be a piezoelectric ceramic sound sensor, a Micro-Electro-Mechanical System-MEMS (Micro-Electro-Mechanical System-MEMS), a fiber optic sound sensor, or the like. The optical fiber sound sensor is less influenced by a magnetic field and can be used in a high magnetic field or an ultrahigh magnetic field.

In the present embodiment, the sound sensor 20 is used to collect sounds generated by the movement of the watch, and generates a watch sound signal according to the collected sounds.

Specifically, after the test is started, the watch is placed in a magnetic field-free environment to operate in the magnetic field-free environment, and the first sound signal is a signal generated after the sound sensor 20 collects sound emitted by the watch when the watch operates in the magnetic field-free environment. The magnetic field-free environment is an environment to which no magnetic field is added. The sound sensor 20 transmits the first phonogram signal to the sound processing module 30. After obtaining the first sound-indicating signal, the sound processing module 30 processes the first sound-indicating signal to obtain a first parameter. The sound processing module 30 may perform processing on the first voice-form signal, including signal conversion, signal amplification, signal filtering, and the like. The first parameter includes at least one of a first instantaneous day-difference, a first swing, and a first polarization. The sound processing module 30 sends the first parameter to the controller. Instantaneous day-to-day difference is the error in the travel time of the watch measured over a short time interval. The swing amplitude is the amplitude of the left-right swing of the balance wheel in the watch when the balance wheel oscillates. When the balance wheel is at rest, the balance wheel pin deviates from the central line of the escapement, so that the left and right swing amplitudes of the balance wheel are inconsistent when the balance wheel oscillates, and the difference value of the left and right swing amplitudes is used as polarization. In this embodiment, the first instantaneous day difference, the first swing, and the first polarization may all be obtained based on the first phonogram signal.

Specifically, after the first parameter is obtained, the watch is placed in a magnetic field in a preset direction, so that the watch is in a magnetic field environment. The preset direction can be set according to the requirement, for example, the preset direction can be the 3H-9H direction, the 6H-12H direction, the CH-FH direction and the like of the watch.

The sound sensor 20 collects the sound emitted by the watch when it is in a magnetic field environment and generates a third sounding signal from the collected sound. The sound sensor 20 sends the third sound signal to the sound processing module 30. After obtaining the third sound signal, the sound processing module 30 processes the third sound signal to obtain a third parameter. The process of obtaining the third parameter according to the third sound signal by the sound processing module 30 is the same as the process of obtaining the first parameter according to the first sound signal, please refer to the process of obtaining the first parameter. The third parameter includes at least one of a third instantaneous day-difference, a third swing, and a third polarization. The sound processing module 30 sends the third parameter to the controller 10. The third parameter may be of the same type as the first parameter.

Specifically, after the watch runs for a preset time in a magnetic field environment, the watch is taken out of the magnetic field environment and placed in a non-magnetic field environment, or the magnetic field is removed, so that the watch enters the non-magnetic field environment. When the watch is again in a magnetic field-free environment, the sound sensor 20 collects the sound emitted when the watch is in a magnetic field-free environment, and generates a second sound signal according to the collected sound. The sound sensor 20 sends a second phonogram signal to the sound processing module 30. The sound processing module 30 obtains a second parameter according to the second voice-indicating signal and sends the second parameter to the controller 10. The second parameter includes at least one of a second instantaneous day-difference, a second swing, and a second polarization. The category of the second parameter is the same as the category of the first parameter. For example, if the first parameter comprises a first instantaneous day difference, the second parameter comprises a second instantaneous day difference.

In a possible implementation manner, the controller 10 is configured to receive the first parameter and the second parameter sent by the sound processing module 30, and obtain the antimagnetic coefficient of the watch based on the first parameter and the second parameter.

In this embodiment, if the second parameter is a preset value, for example, the preset value is 0, it is determined that the travel time state of the watch is a stop state. And if the second parameter is not a preset value, determining that the travel time state of the watch is an operating state.

In this embodiment, if the first parameter includes a first instantaneous day difference and the second parameter includes a second instantaneous day difference, a first difference between the first instantaneous day difference and the second instantaneous day difference is calculated, and the antimagnetic coefficient includes the first difference.

If the first parameter comprises a first swing and the second parameter comprises a second swing, calculating a second difference value between the first swing and the second swing, and the antimagnetic coefficient comprises the second difference value.

If the first parameter comprises the first polarization and the second parameter comprises the second polarization, calculating a third difference value between the first polarization and the second polarization, and the antimagnetic coefficient comprises the third difference value.

Optionally, if the first parameter includes a first instantaneous day difference, a first polarization, and a first swing, after the first difference, the second difference, and the third difference are obtained, the antimagnetic coefficient may be calculated according to a weight corresponding to each difference.

Specifically, the antimagnetic coefficient may be obtained from an antimagnetic coefficient calculation formula u — a × a + B × B + C × C. Wherein u is the antimagnetic coefficient, a is the first difference, a is the first weight corresponding to the first difference, B is the second weight corresponding to the second difference, C is the third difference, and C is the third weight corresponding to the third difference.

In this embodiment, after obtaining the antimagnetic coefficient, the controller 10 may present the antimagnetic coefficient to the user, so that the user can determine the antimagnetic performance of the watch according to the antimagnetic coefficient.

In the embodiment of the application, the controller 10 first obtains a first parameter when the watch operates in a magnetic field-free environment and a second parameter when the watch operates in the magnetic field-free environment; and obtaining the antimagnetic coefficient of the watch based on the first parameter and the second parameter. The antimagnetic performance of the watch can be determined through the antimagnetic coefficient, and compared with the antimagnetic effect of a manual test watch, the antimagnetic test method and the device have the advantages that the antimagnetic test automation is realized, and the test speed is higher and more accurate.

In a possible implementation, the controller 10 is further configured to receive a third parameter sent by the sound processing module 30, and determine the watch movement state based on the third parameter.

Specifically, if the third parameter is a preset value, for example, the preset value is 0 or 0.1, etc., it is determined that the watch is in the stopped state. And if the third parameter is not a preset value, determining that the walking state of the watch is the running state.

Optionally, when it is determined that the walking state of the watch is the running state, the controller 10 controls the sound sensor 20 to collect a second watch sound signal, and the sound processing module 30 sends the second parameter to the controller 10 after obtaining the second parameter. Or when the walking state of the watch is determined to be the running state, the controller 10 acquires the second parameter again, and obtains the antimagnetic coefficient according to the first parameter and the second parameter.

Optionally, when it is determined that the walking state of the watch is the running state and the type of the third parameter is the same as the first parameter, the controller 10 may further calculate a difference between the third parameter and the first parameter. If the difference between the third parameter and the first parameter is within the preset interval, the controller 10 controls the sound sensor 20 to acquire a second sound signal, the sound processing module 30 sends the second parameter to the controller 10 after obtaining the second parameter, and the controller 10 receives the second parameter and obtains the antimagnetic coefficient according to the first parameter and the second parameter. Or, if the difference between the third parameter and the first parameter is within the preset interval, the controller 10 obtains the second parameter again, and obtains the antimagnetic coefficient according to the first parameter and the second parameter.

Optionally, if the type of the third parameter is the same as that of the first parameter, the antimagnetic coefficient may also be obtained according to the first parameter and the third parameter.

Specifically, if the third parameter includes the third instantaneous day difference and the first parameter includes the first instantaneous day difference, a fourth difference between the third instantaneous day difference and the first instantaneous day difference is calculated. And if the fourth difference value is within the fourth interval, determining that the difference value between the third parameter and the first parameter is within the preset interval. The preset interval includes a fourth interval. In addition, the antimagnetic coefficient may include a fourth difference value.

If the third parameter comprises the third polarization and the first parameter comprises the first polarization, calculating a fifth difference between the third polarization and the first polarization. And if the fifth difference value is within a fifth interval, determining that the difference value between the third parameter and the first parameter is within a preset interval. The preset interval includes a fifth interval. The antimagnetic coefficient may include a fifth difference value.

If the third parameter includes the third swing and the first parameter includes the first swing, a sixth difference between the third swing and the first swing is calculated. And if the sixth difference value is within a sixth interval, determining that the difference value between the third parameter and the first parameter is within a preset interval. The preset section includes a sixth section. The antimagnetic coefficient includes a sixth difference.

Additionally, if the third parameter comprises at least two of a third instantaneous day-difference, a third swing, and a third polarization. The difference value between the third parameter and the first parameter can be determined to be within a preset interval only when the difference values corresponding to the included parameters are within corresponding intervals.

In a possible implementation manner, the controller 10 is configured to receive the first sound signal, the second sound signal, and the third sound signal sent by the sound sensor 20. The controller 10 obtains a first parameter according to the first voice-indicating signal. The controller 10 obtains a second parameter according to the second voice-indicating signal. The controller 10 obtains a third parameter according to the third sounding signal.

Specifically, the process of the controller 10 obtaining the first parameter according to the first voice-indicating signal is the same as the process of the sound processing module 30 obtaining the first parameter according to the first voice-indicating signal, please refer to the above. The process of the controller 10 obtaining the second parameter according to the second sound-indicating signal is the same as the process of the sound processing module 30 obtaining the second parameter according to the second sound-indicating signal, please refer to the above. The process of obtaining the third parameter by the controller 10 according to the third sound signal is the same as the process of obtaining the third parameter by the sound processing module 30 according to the third sound signal, please refer to the above description.

In a possible implementation manner, after the controller 10 obtains the antimagnetic coefficient, the controller 10 is further configured to determine whether the watch meets the antimagnetic requirement according to the antimagnetic coefficient.

In this embodiment, if the antimagnetic coefficient is within the preset interval, it is determined that the watch meets the antimagnetic requirement. And if the antimagnetic coefficient is not in the preset interval, determining that the watch does not meet the antimagnetic requirement. Specifically, if the difference values included in the antimagnetic coefficients are all in the corresponding intervals, the watch is determined to meet the antimagnetic requirement. The difference of the parameters of one category corresponds to one interval.

And if the antimagnetic coefficient comprises a first difference value, and the first difference value is within a first interval, determining that the watch meets the antimagnetic requirement. The first interval is set as needed, for example, the first interval may be determined according to the model of the watch. The preset interval includes a first interval. And if the first difference value is not in the first interval, determining that the watch does not meet the antimagnetic requirement.

And if the antimagnetic coefficient comprises a second difference value, and the second difference value is within a second interval, determining that the watch meets the antimagnetic requirement. The second interval may be set as needed. The preset interval includes a second interval. And if the second difference value is not in the second interval, determining that the watch does not meet the antimagnetic requirement.

And if the antimagnetic coefficient comprises a third difference value, and the third difference value is within a third interval, determining that the watch meets the antimagnetic requirement. The third interval may be set as needed. The preset interval includes a third interval. And if the third difference is not in the third interval, determining that the watch does not meet the antimagnetic requirement.

If the antimagnetic coefficients include at least two of the first difference value, the second difference value and the third difference value, it can be determined that the watch satisfies the antimagnetic coefficients only if the first difference value, the second difference value and the third difference value which need to be included are within respective corresponding intervals. And if at least one of the first difference value, the second difference value and the third difference value is not in the corresponding interval, determining that the watch does not meet the antimagnetic requirement.

By way of example, if the first parameter comprises a first instantaneous day-to-difference and a first swing, the second parameter comprises a second instantaneous day-to-difference and a second swing. A first difference value of the first instantaneous day difference and the second instantaneous day difference is calculated. A second difference between the first swing and the second swing is calculated. The antimagnetic coefficient includes a first difference and a second difference. And if the first difference value is within the first interval and the second difference value is within the second interval, determining that the watch meets the antimagnetic requirement. And if the first difference value is not in the first interval and the second difference value is in the second interval, determining that the watch does not meet the antimagnetic requirement.

Optionally, if the antimagnetic coefficient includes at least one of a fourth difference, a fifth difference, and a sixth difference, and the fourth difference, the fifth difference, and/or the sixth difference that are included are all within the corresponding interval, it may be determined that the watch satisfies the antimagnetic requirement. And if the difference value which is not in the corresponding interval exists in the antimagnetic coefficient, determining that the watch does not meet the antimagnetic requirement. The fourth difference corresponds to a fourth interval, the fifth difference corresponds to a fifth interval, and the sixth difference corresponds to a sixth interval.

For example, if the antimagnetic coefficient includes a first difference value and a fourth difference value, if the first difference value is within a first interval and the fourth difference value is within a fourth interval, it is determined that the watch satisfies the antimagnetic requirement. And if the first difference value is within the first interval and the fourth difference value is not within the fourth interval, determining that the watch does not meet the antimagnetic requirement.

In this embodiment, if the antimagnetic coefficient is calculated according to the above antimagnetic coefficient calculation formula, and if the antimagnetic coefficient is within the seventh interval, it is determined that the watch satisfies the antimagnetic requirement. And if the antimagnetic coefficient is not in the seventh interval, determining that the watch does not meet the antimagnetic requirement. The preset intervals include a seventh interval.

In the embodiment of the application, whether the watch meets the antimagnetic requirement or not is judged through the controller, so that the trouble of manual judgment is eliminated, and a user can clearly obtain the test result of the watch.

In one possible implementation, the system may further include a magnetic field generating device 40 and a bracket 50. The magnetic field generating device 40 is used to emit a demagnetizing field and a dc magnetic field. The magnetic field generating device 40 and the holder 50 are both connected to a controller. The controller 10 is used to control the movement of the carriage 50.

Specifically, when the antimagnetic test is performed on the watch, the operating parameters of the watch in a non-magnetic field environment need to be obtained first, and the operating parameters of the watch in the non-magnetic field environment are taken as reference parameters and are recorded as first parameters in the application. Therefore, when the antimagnetic test is performed on the watch, the controller 10 needs to send a first command to the magnetic-field-generating device 40. The magnetic field generating device 40 generates a demagnetizing field upon receiving a first instruction transmitted from the controller 10. Since the watch needs to be horizontally placed in the demagnetizing field, the watch may be placed on a bracket disposed in the demagnetizing field, for example, the bracket 50 may be placed at the center of the demagnetizing field. And the demagnetization magnetic field is used for performing demagnetization treatment on the watch. The direction of the demagnetizing field emitted by the magnetic field generating device 40 can be set as required, for example, the direction of the demagnetizing field can include a 3H-9H direction, a 6H-12H direction, a CH-FH direction, and the like. The direction of the demagnetizing field can also be determined according to the direction of the direct current magnetic field. The demagnetization magnetic field may include one or more of alternating current demagnetization, alternating current decaying demagnetization, and direct current demagnetization. The strength of the demagnetization magnetic field may be set as needed, for example, the strength of the demagnetization magnetic field may be set to 13mT or 14mT or the like.

Before the operation parameters of the watch in the magnetic field-free environment are collected, the watch is demagnetized, the influence of a magnetic field carried by the watch on the operation parameters of the watch is avoided, and the accurate operation parameters of the watch in the magnetic field-free environment can be obtained.

Specifically, after the controller 10 sends the first instruction for a first preset time, the controller 10 may send a second instruction to the magnetic field generating device 40, and the magnetic field generating device 40 stops operating after receiving the second instruction sent by the controller 10.

In this embodiment, after the watch is demagnetized for a period of time, the magnetic field generating device may stop operating, so that the magnetic field generating device stops emitting the demagnetizing field, and the watch is placed in a magnetic field-free environment. When the magnetic field generating equipment stops operating, acquiring a first parameter of the watch operating in a magnetic field-free environment.

Specifically, when a third parameter of the watch running in a magnetic field environment needs to be acquired, the controller 10 needs to send a third instruction to the magnetic field generating device 40, and the magnetic field generating device 40 generates a dc magnetic field for a preset time after receiving the third instruction sent by the controller 10. The direction of the dc magnetic field can be set as desired. The direction of the dc magnetic field generated by the magnetic field generating device 40 may be one direction or a plurality of directions, for example, the direction of the dc magnetic field may be a 3H-9H direction, a 6H-12H direction, a CH-FH direction, or the like. The holder 50 is placed in a dc magnetic field. When the magnetic field generating device 40 emits a dc magnetic field, a third parameter of the watch operating in a magnetic field environment is obtained.

Specifically, after the magnetic field generating device 40 sends out the dc magnetic field for the preset time, the magnetic field generating device 40 stops sending out the dc magnetic field, and the watch enters a magnetic field-free environment. The sound sensor 20 acquires a second voice signal of the watch.

Specifically, after the controller 10 obtains the antimagnetic factor, the controller 10 may send a first command to the magnetic field generating device 40, and the magnetic field generating device 40 generates a demagnetization magnetic field to perform demagnetization on the watch. If the second parameter of the watch needs to be obtained continuously, the controller 10 sends a third instruction to the magnetic field generating device 40 again to enable the magnetic field generating device 40 to send a direct-current magnetic field different from the previous direction, the watch is placed in the direct-current magnetic field for a preset time, and after the controller 10 obtains the second parameter, the controller 10 obtains the antimagnetic coefficient again according to the first parameter and the obtained second parameter. And then, whether the acquired antimagnetic coefficient is within the preset interval or not can be judged, and whether the watch meets the antimagnetic requirement or not is further determined. By analogy, the antimagnetic coefficient obtained by multiple tests can be obtained. And if the antimagnetic coefficients obtained by multiple tests are all in a preset interval, determining that the watch meets the antimagnetic requirement. And if the antimagnetic coefficients which are not in the preset interval exist in the antimagnetic coefficients obtained by the multiple tests, determining that the watch does not meet the antimagnetic requirement.

Alternatively, the magnetic field generating device 40 may be a single device, and the magnetic field generating device 40 may emit a demagnetizing field or a dc magnetic field. Alternatively, the magnetic field generating device 40 may include a demagnetization generating means and a direct current magnetic field means. The demagnetization generator is used for emitting a demagnetization magnetic field, and the direct-current magnetic field device is used for emitting a direct-current magnetic field.

In particular, the magnetic field generating device 40 may comprise a magnetic field generator or a plurality of magnetic field generators, which are controlled by an electric motor. The motor controls the magnetic field generator to rotate so as to emit magnetic fields in different directions. If the magnetic field generating device comprises a plurality of magnetic field generators, the plurality of magnetic field generators are adapted to emit magnetic fields in different directions. The magnetic fields generated by the plurality of magnetic field generators may intersect at a point at which the watch may be placed.

Alternatively, the magnetic field generating device may comprise a magnetic field generator and at least two motors, one motor being operable to drive the magnetic field generator and the other motor being operable to drive the support. The magnetic field generator or the bracket is controlled by the motor to obtain magnetic fields in at least three directions. The magnetic field generating device may further comprise two magnetic field generators and at least one motor, the at least one motor driving the magnetic field generators to index. The two magnetic field generators may be mounted vertically with the centers of the magnetic fields coinciding. X, Y, Z magnetic fields in three directions can be realized by controlling one magnetic field generator to rotate through the motor to obtain a magnetic field in the other direction. The magnetic field generating device may further comprise three or more magnetic field generators providing magnetic fields of at least X, Y, Z directions. The three directional magnetic fields may include the directional magnetic fields of watches 3H-9H, 6H-12H, CF-FH, etc.

In this embodiment, the watch bottom cover of the watch is in contact with the upper surface of the holder. The carriage 50 may be connected to a motor. The controller 10 controls the rotation of the motor to rotate the bracket, so as to adjust the position and the direction of the watch. The sound sensor 20 may be provided on a support, the sound sensor 20 being in contact with the watch. The sound sensor 20 may also be connected to the bracket 50 by a connecting rod. One end of the connecting rod is connected with the sound sensor, and the other end of the connecting rod is in contact with the watch.
