Description

Technical Field

[0001] The present invention relates to the technical field of personnel alert reminder scheme design, and in particular to a personnel alert reminder method and system. Background Art

[0002] Considering the need for safe production in the mine, the hoisting system room is equipped with a main driver and a deputy driver for each shift. The main driver is mainly responsible for operating the vehicle and observing the operating status of the winch, while the deputy driver is responsible for monitoring the main driver's driving status, operating actions, and whether the indications of the various instruments and indicator lights on the operating console are correct, so as to correct them in time when problems are found, and remind the main driver to take corresponding measures. Since the main driver is in a state of mental tension for a long time during the operation process, fatigue and slackness are inevitable. The main and deputy drivers are required to rotate every hour, which can theoretically achieve a short rest. However, according to actual observations, after the main and deputy drivers rotate, the original main driver (now the deputy driver) is still in a state of mental tension. This will cause the two drivers to be inattentive at the same time. As long as the time of inattention exceeds a certain period of time, or the main driver and the deputy driver enter an unconscious state such as sleep at the same time, it is easy to induce the occurrence of hoisting accidents due to misoperation or inadequate monitoring. However, in the prior art, the scheme of image training is often unable to determine whether the main driver and the co-driver enter an unconscious state such as sleep at the same time. Therefore, a personnel alert reminder scheme is urgently needed to solve the problems existing in the prior art.

DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0018] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0019] See also Figure 1 The present invention provides a method for alerting personnel, comprising: S100, obtaining the operating status data of the main and auxiliary shaft winches, and judging whether the gate handle is in the zero position according to the operating status data of the main and auxiliary shaft winches; judging whether to open the first timer according to the judgment result, and recording the first duration when the gate handle is not in the zero position.

[0020] It should be noted that the steps before step S100 include: A first preset threshold, a second preset threshold, a third preset threshold, and a preset ratio are preset in the control module.

[0021] It can be understood that the first preset threshold, the second preset threshold, the third preset threshold and the preset ratio can be set according to actual needs. The present invention does not limit the specific values ​​of the first preset threshold, the second preset threshold, the third preset threshold and the preset ratio. There is no regularity in setting the specific values ​​of the above parameters, as long as they are applicable to the personnel alert reminder method proposed in the present invention.

[0022] Preferably, the first preset threshold is preferably 12 minutes, the second preset threshold is preferably 15 minutes, the third preset threshold is preferably 3 minutes, and the preset ratio is preferably 60%. The above parameters are obtained by the technicians of the present invention through a large number of tests, and can well illustrate the personnel alert reminder method proposed by the present invention.

[0023] It should be noted here that judging whether the gate handle is in the zero position based on the operating status data of the main and auxiliary shaft winches is a prior art, and the present invention will not be described in detail here. For example, the winch system is equipped with a position sensor, such as a proximity switch or an encoder, and the sensor output signal can be checked to judge the gate handle position. At this time, the operating status data of the main and auxiliary shaft winches include the sensor data collected by the position sensor. When in the zero position, the position sensor should send a preset reference signal. By controlling the reading and confirming this signal, it can be judged whether the gate handle is in the zero position.

[0024] Specifically, the step of determining whether to start the first timer according to the judgment result and recording the first duration of the gate handle not being in the zero position is: If the gate handle is not in the zero position, start a first timer to record a first duration of time when the gate handle is not in the zero position; If the gate handle is at the zero position, the first timer is reset to zero and closed.

[0025] S200, determining whether the first duration is greater than or equal to a first preset threshold, and determining whether a closing signal of the alert release button is received within a time corresponding to the first preset threshold, and determining whether to control the warning light to be always on or control the first timer to be reset and re-record the first duration based on the determination result.

[0026] It should be noted here that the alert contact button, warning light and buzzer are all arranged on the control panel of the cab.

[0027] Specifically, the determining whether the first duration is greater than or equal to a first preset threshold, and determining whether a closing signal of the alert release button is received within a time corresponding to the first preset threshold, and determining whether to control the warning light to be always on or control the first timer to be reset and re-record the first duration according to the determination result, includes: If the first duration is greater than or equal to the first preset threshold and no closing signal of the alert release button is received within the time corresponding to the first preset threshold, the warning light is controlled to be always on, the first timer is not controlled to be reset, and the first duration is not re-recorded.

[0028] Specifically, the determining whether the first duration is greater than or equal to a first preset threshold, and determining whether a closing signal of the alert release button is received within a time corresponding to the first preset threshold, and determining whether to control the warning light to be always on or control the first timer to be reset and re-record the first duration according to the determination result, further includes: If the first duration is less than the first preset threshold, or a closing signal of the alert release button is received within the time corresponding to the first preset threshold, the warning light is not controlled to be always on, the first timer is reset to zero, and the first duration is re-recorded.

[0029] S300, determining whether the first duration is greater than or equal to a second preset threshold, and determining whether a closing signal of the alert release button is received within a time period corresponding to the second preset threshold, and determining whether to control the buzzer to alarm or control the first timer to be reset and re-record the first duration based on the determination result.

[0030] Specifically, the determining whether the first duration is greater than or equal to the second preset threshold, and determining whether a closing signal of the alert release button is received within the time corresponding to the second preset threshold, and determining whether to control the buzzer to alarm or control the first timer to reset and re-record the first duration according to the determination result, includes: If the first duration is greater than or equal to the second preset threshold, and the closing signal of the alert release button is not received within the time corresponding to the second preset threshold, the buzzer is controlled to alarm, the first timer is not controlled to be reset, and the first duration is not re-recorded.

[0031] Specifically, the determining whether the first duration is greater than or equal to a second preset threshold, and determining whether a closing signal of the alert release button is received within a time corresponding to the second preset threshold, and determining whether to control a buzzer to sound an alarm or control the first timer to reset and re-record the first duration according to the determination result, further includes: If the first duration is less than the second preset threshold, or a closing signal of the alert release button is received within the time corresponding to the second preset threshold, the buzzer is not controlled to alarm, the first timer is controlled to be reset, and the first duration is re-recorded.

[0032] Specifically, the first preset threshold is smaller than the second preset threshold, and the third preset threshold is smaller than the first preset threshold.

[0033] S400. After the first timer starts timing, the second timer is turned on, and the pressure array data is obtained at preset time intervals using the pressure sensor arrays that are evenly arranged under the main driver's seat and under the co-driver's seat according to preset numbers of rows and columns, and then a second duration in which the pressure data exceeding a preset proportion in the pressure array data do not change is calculated, and it is determined whether the second duration is greater than or equal to a third preset threshold, and whether a closing signal of the alert release button is received within the time corresponding to the third preset threshold, and based on the determination result, it is determined whether to output to the background an alarm signal that the sitting posture of the main driver and the co-driver has not changed significantly for a long time, or to control the second timer to be reset and re-record the second duration.

[0034] It is understandable that if the sitting posture of the main driver or the co-driver changes, one of the pressure data in the pressure array data will definitely change, and if the main driver or the co-driver enters a sleep state at the same time, there may still be subtle movements. Therefore, the present invention sets the preset ratio to 60%, and requires the sitting posture of the main driver or the co-driver to be frequently and obviously readjusted, further improving the safety and reliability of the personnel alert reminder of the present invention.

[0035] Specifically, the determining whether the second duration is greater than or equal to a third preset threshold, and determining whether a closing signal of the alert release button is received within a time corresponding to the third preset threshold, and determining whether to output to the background an alarm signal that the sitting postures of the primary driver and the secondary driver have not changed significantly for a long time, or controlling the second timer to be reset and re-recording the second duration according to the determination result, includes: If the second duration is greater than or equal to the third preset threshold, and no closing signal of the alert release button is received within the time corresponding to the third preset threshold, an alarm signal is output to the background indicating that the sitting posture of the main driver and the co-driver has not changed significantly for a long time, the second timer is not reset, the second duration is not re-recorded, the buzzer is controlled to alarm, and the warning light is controlled to be always on.

[0036] It should be noted here that an alarm signal is output to the backend through the cloud server regarding the main driver and the co-driver's sitting posture not changing significantly for a long time.

[0037] It can be understood that if the second duration is greater than or equal to the third preset threshold, and no closing signal of the alert release button is received within the time corresponding to the third preset threshold, it proves that the sitting posture of the main driver and the co-driver has not changed significantly within 3 minutes, that is, the sitting posture of the main driver and the co-driver can be deemed that neither of them has actively made obvious adjustments. At this time, the main driver and the co-driver may be distracted at the same time, or enter an unconscious state such as sleep at the same time. At this time, an alarm is needed, and an alarm signal about the main driver and the co-driver's sitting posture not changing significantly for a long time needs to be output to the background through the cloud server to prevent the main driver and the co-driver from failing to recover to a conscious state in time due to deep sleep or injury, etc., further improving the intelligence and usability of the present invention and further expanding the application scenarios of the present invention.

[0038] Specifically, the determining whether the second duration is greater than or equal to a third preset threshold, and determining whether a closing signal of the alert release button is received within a time corresponding to the third preset threshold, and determining whether to output to the background an alarm signal that the sitting postures of the primary driver and the secondary driver have not changed significantly for a long time, or controlling the second timer to be reset and re-recording the second duration, according to the determination result, also includes: If the second duration is less than the third preset threshold, or a closing signal of the alert release button is received within the time corresponding to the third preset threshold, no alarm signal about the main driver and the co-driver's sitting posture not changing significantly for a long time will be output to the background, the second timer will be reset, the second duration will be re-recorded, the buzzer will stop alarming, and the warning light will be turned off.

[0039] It can be understood that the present invention uses technical means to intervene in the whole process of winch driver's operation, effectively improves the standardized management of driver's operation, provides a protective measure for the safe operation of the main hoisting system, and also provides a good example for the development of the early warning (alarm) function of the main hoisting system in the future.

The present invention is practical, does not require complex algorithm training, has low investment, high safety benefits, and enriches the protection function of the main shaft hoist. The present invention takes effective preventive measures from the root cause of the fault, and has very high feasibility; it greatly improves the intelligence and usability of the present invention and greatly expands the application scenarios of the present invention.

[0040] See also Figure 2 The present invention provides another embodiment, which provides a personnel alert reminder system, the personnel alert reminder system comprising: The acquisition module 100 is used to obtain the operating status data of the main and auxiliary well winches. The control module 200 is used to determine whether the gate handle is in the zero position according to the operating status data of the main and auxiliary shaft winches, determine whether to open the first timer according to the judgment result, and record the first duration when the gate handle is not in the zero position; or to determine whether the first duration is greater than or equal to the first preset threshold, and determine whether a closing signal of the alert release button is received within the time corresponding to the first preset threshold, and determine whether to control the warning light to be always on or control the first timer to be reset and re-record the first duration according to the judgment result; or to determine whether the first duration is greater than or equal to the second preset threshold, and determine whether a closing signal of the alert release button is received within the time corresponding to the second preset threshold, and determine whether to control the buzzer to alarm or control the first timer to be reset according to the judgment result. And re-record the first duration; or used to start the second timer after the first timer starts timing, and use the pressure sensor arrays that are evenly arranged under the main driver's seat and under the co-driver's seat according to preset rows and columns to obtain pressure array data at preset time intervals, and then calculate the second duration during which the pressure data exceeding a preset proportion in the pressure array data has not changed, determine whether the second duration is greater than or equal to a third preset threshold, and determine whether a closing signal of the alert release button is received within the time corresponding to the third preset threshold, and determine whether to output an alarm signal to the background that the sitting posture of the main driver and the co-driver has not changed significantly for a long time based on the judgment result, or control the second timer to be reset and re-record the second duration.
