Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
Before describing the method in detail, it is first necessary to divide the area within the plant, as shown in fig. 3. The areas within the plant include hazardous areas, safe buffer areas, and safe areas. The dividing method specifically comprises the following steps: the location of the hazardous area is first determined. In this embodiment, the hazardous area refers to a station or an equipment installation position with a high risk coefficient inside the plant, and an inner warning line is first defined on the periphery of the hazardous area, and separates the hazardous area from the safety buffer area. An outer warning line is arranged on the outer side of the inner warning line, and the area between the inner warning line and the outer warning line is a safety buffer area. Wherein the distance between the inner warning line and the outer warning line is preferably 1 meter, which has the advantage that staff is prevented from crossing the safety buffer zone in one step.
The following describes a warning method and a warning system according to an embodiment of the present invention in detail with reference to the accompanying drawings.
Fig. 1 is a flowchart of a first embodiment of an alert method according to the present invention, which can be executed by an alert system. The method is used for warning workers in a factory, and a warning system is arranged in a working area; the warning method specifically comprises the following steps:
step 110, detecting the position information of the staff by an alarm system;
it should be noted that the main functions of the warning system are: and positioning the staff, and sending a touch warning signal by the warning system when the position information of the staff meets a preset condition. The warning system can be constructed in various ways, which will be described below:
the first mode is as follows: the warning system includes: the laser positioning device is arranged in a working area, and the laser positioning device is worn on a worker;
in a second aspect, a warning system includes: the system comprises camera positioning equipment arranged in a working area and touch signal output equipment worn on a worker;
in a third aspect, a warning system includes: and the magnetic adsorption equipment is worn on the body of the worker.
In the first mode, a laser reflection device (laser positioning device) may be disposed at a corner of the safety buffer area, and the laser positioning device may be disposed on a worker. When the warning system is used for positioning, workers enter the safety buffer area, and can be positioned through the mutual matching of the laser reflection equipment and the laser positioning equipment. Wherein, laser positioning equipment can set up on staff's safety shoes, also can set up on wearable vest.
In the second mode, a camera can be arranged at a corner of the safety buffer area, and a tactile signal output device is arranged on a worker. When the warning system is used for positioning, the camera acquires image information in the safety buffer area, and the safety area is identified by using a graphic image identification algorithm, so that workers entering the safety buffer area are positioned. Wherein, the tactile signal output device arranged on the body of the worker can be arranged on the wearable vest or the safety shoes of the worker.
In the third mode, a magnetic wire or a metal wire may be laid on the ground of the safety buffer area, and the inner warning line and the outer warning line may be selected from the metal wire or the magnetic wire. Like this, warning system is when fixing a position, when wearing magnetic adsorption equipment staff and get into in the safety zone, and the magnetic induction line in the safety buffer zone changes to the realization can be to staff's location.
120, when the warning system detects that the worker is in the safety buffer area and the distance between the worker and the inner warning line is smaller than a preset first threshold value, generating a tactile warning signal;
when the warning system detects that the staff enters the safety buffer area in step 110, the distance between the staff and the inner warning line is further determined. If the staff is relatively far away from the inner warning line, the staff is still relatively safe at the moment, and the tactile warning signal is not required to be sent out at the moment. When the distance between the staff and the inner warning line is smaller than the specific distance, the staff is considered to be in a dangerous state at the moment, and a tactile warning signal needs to be sent out. Wherein, the sense of touch warning signal is initiative warning signal, for traditional reputation or graphics signal, sense of touch warning signal is difficult to be ignored by the workman.
Step 130, outputting a tactile warning signal by a warning system, and sending warning information to a worker;
in particular, the haptic alert signal may include: at least one of a vibration signal, a weak current signal, or a magnetic attraction signal. The warning system outputs a specific type of tactile warning signal, which depends on the specific configuration of the warning system.
For example, when the warning system is configured as the first mode described above, that is, when the warning system includes a laser positioning device disposed in a work area and a laser positioning device worn on a worker, the laser positioning device may be used as a signal output device to output a vibration signal and/or a weak current signal. When the warning system is configured in the second mode, the tactile signal output device can be a safety shoe or a wearable vest and outputs a vibration signal and/or a weak current signal. When the warning system is configured in the third mode, the output tactile warning signal may be a magnetic attraction signal. Among the aforementioned three kinds of modes, the vibration signal of output, weak current signal or magnetic force adsorb the signal, all through direct action staff's health, what send the staff promptly is initiative warning information, for traditional passive warning information (audible and visual alarm information), has the advantage that even can not be ignored by the staff in noisy chaotic environment.
According to the embodiment of the invention, the safety buffer area is defined at the outer side of the dangerous area, the safety buffer area and the dangerous area are separated by the inner warning line, the position information of the working personnel is detected by the warning system, and the corresponding tactile warning signal is sent to the working personnel when the working personnel enters the safety buffer area and the distance between the working personnel and the inner warning line meets the preset condition, and the tactile warning signal directly acts on the body of the working personnel. That is to say, the embodiment of the present invention sends the active warning information to the worker, and has a benefit that the active warning information is not ignored by the worker even in a noisy and chaotic environment, compared with the conventional passive warning information (audible and visual warning information).
Through the warning method, the dangerous area can be isolated, when workers are close to the dangerous area, the warning system outputs the touch warning information, so that the behaviors that the workers enter the dangerous area are reminded or prevented, the problem that personal and property safety is damaged due to the fact that the workers mistakenly enter the dangerous area is avoided, compared with the passive methods that light and sound prompt are only used in the existing design, active and forced intervention means can limit workers in a safety buffer area, the situation that the workers ignore sound and light warning and enter the dangerous area due to the noisy sound and light environment in a factory is prevented, meanwhile, the workers with low safety consciousness can be prevented from intentionally being close to the dangerous area, workers are protected, and production is guaranteed.
It should be noted that, in an optimized embodiment, the warning system may specifically include: magnetic force adsorption equipment worn on a worker, such as magnetic force adsorption safety shoes worn on the feet of the worker. Correspondingly, the tactile warning signal at this time is specifically a magnetic force adsorption signal, and the ground of the safety buffer area is a magnetic wire or a metal wire at this time.
At the moment, when the magnetic adsorption equipment detects that the worker enters the safety buffer area and the distance between the worker and the inner warning line is smaller than the preset threshold value, the magnetic adsorption equipment sends out a magnetic adsorption signal to adsorb the worker in the safety buffer area, and the purpose of preventing the worker from entering the dangerous area is achieved. It can be understood that the magnetic force adsorption device can adjust the intensity of the output magnetic force adsorption signal according to the distance between the worker and the inner alarm line, and the closer the worker is to the inner alarm line, the stronger the output magnetic force adsorption signal.
Fig. 2 is a flowchart of a dangerous area warning method according to a second embodiment of the present invention, which may be implemented by a magnetic adsorption device, for warning staff in a plant, wherein the working area of the plant includes: the safety buffer area is arranged at the periphery of the dangerous area; the safety buffer area is separated from the dangerous area by an inner warning line; the worker wears magnetic adsorption equipment; the method comprises the following steps:
s1, detecting the position information of the staff by the magnetic adsorption equipment;
the principle that the magnetic adsorption equipment detects the position information of the workers is as follows:
the staff dresses this magnetic force adsorption equipment on one's body to set up the ground of safety buffer area in the mill into sheet metal and lay, for example, magnetic wire or metal wire are chooseed for use to safety buffer area's ground. Therefore, when a worker approaches or enters the safety buffer area, the magnetic induction lines can be changed, and therefore the worker can be positioned.
During specific positioning, a distance threshold value, namely a later second threshold value, can be set between the magnetic adsorption equipment and the outer warning line, and is used for determining whether to start the positioning function of the magnetic adsorption equipment or not, so that the magnetic adsorption equipment plays a role of triggering a switch. The range of the distance threshold value can be 0-0.5m, and is preferably 0.1, namely when the magnetic adsorption device detects that the distance between the magnetic adsorption device and the outer warning line is less than 0.1, the positioning function of the magnetic adsorption device is started to position the real-time position of the worker. That is, only when the staff is close to the outer warning line, that is, about to enter the safety buffer area, the magnetic force adsorption equipment will detect the position of the staff.
The purpose of setting the second threshold value is to use the second threshold value as a working signal for triggering the magnetic adsorption equipment to start positioning, so that part of components in the magnetic adsorption equipment do not work when being far away from a dangerous area, and excessive electric quantity waste is avoided.
S2, when the magnetic adsorption equipment detects that the worker is in a safety buffer area and the distance between the worker and the inner warning line is smaller than a preset first threshold value, generating a magnetic adsorption signal;
it should be noted that when the staff enters the safety buffer area between the outer warning line and the inner warning line and approaches the inner warning line, the magnetic force adsorption device will generate a magnetic force adsorption signal. For example, when the distance between the magnetic attraction device and the inner alarm line is less than a first threshold value, a magnetic attraction signal is generated. Wherein the first threshold value is in the range of 0.5-1m, preferably 1m, i.e. when the magnetic force adsorption device detects that the distance between the magnetic force adsorption device and the inner alarm line is less than 1m, the magnetic force adsorption device generates a magnetic force adsorption signal.
And S3, outputting the magnetic adsorption signal by the magnetic adsorption equipment to prevent the staff from entering the dangerous area.
Magnetic force adsorption equipment generates magnetic force and adsorbs the signal and produce magnetic force, because the staff dresses magnetic force adsorption equipment on one's body, the magnetic force that consequently magnetic force adsorption equipment produced will adsorb with the bottom surface in the safety buffer zone to adsorb the staff in the safety buffer zone.
According to the embodiment of the invention, the safety buffer area is defined at the outer side of the dangerous area, the safety buffer area is separated from the dangerous area by the inner warning line, the position information of the worker is detected by the magnetic adsorption equipment, and the corresponding magnetic adsorption signal is sent to the worker when the worker enters the safety buffer area and the distance between the worker and the inner warning line meets the preset condition, and the magnetic adsorption signal directly acts on the body of the worker. That is to say, the embodiment of the present invention sends the active warning information to the worker, and has a benefit that the active warning information is not ignored by the worker even in a noisy and chaotic environment, compared with the conventional passive warning information (audible and visual warning information).
Through the warning method, the dangerous area can be isolated, so that when a worker approaches the dangerous area, a magnetic force adsorption signal is output, the behavior that the worker enters the dangerous area is reminded or prevented, and the problem that personal and property safety is damaged due to the fact that the worker mistakenly enters the dangerous area is avoided.
It should be noted that, in one embodiment, the strength of the magnetic force absorption signal output by the magnetic force absorption device has a correlation with the distance between the staff and the inner alarm line, and the specific correlation may be: the smaller the distance between the staff and the inner warning line is, the stronger the magnetic force adsorption signal output by the magnetic force adsorption equipment is. The advantage of such a design is to ensure that the magnetic force generated is greater the closer the worker is to the hazard zone, thereby achieving the objective of stopping the worker just before the worker crosses the inner warning line into the hazard zone.
At a preferred embodiment, specifically be, when safety shoes were adsorbed in safe buffering region, the staff can't remove this moment, also can't withdraw from safe buffering region, just so this moment need the managers of mill to carry long-range remote switch and cut off the power supply module to safety shoes inside, after the outage, the staff could withdraw from safe buffering region.
The embodiment of the invention defines a safety buffer area outside the dangerous area, the safety buffer area and the dangerous area are separated by an inner warning line, magnetic adsorption equipment is arranged on safety shoes worn by workers, so that the magnetic adsorption equipment can respectively send different signals inside and outside the safety buffer area, if the safety shoes are positioned outside the safety buffer area and the distance between the safety shoes and the outer warning line is less than a set second threshold value, the magnetic adsorption equipment starts a positioning function, after the positioning function is started, if the safety shoes detect that the safety shoes enter the safety buffer area and the distance between the safety shoes and the inner warning line is less than a preset first threshold value, the magnetic adsorption equipment generates and executes a magnetic adsorption signal, so that the safety shoes are adsorbed in the safety buffer area under the action of magnetic force, thereby preventing the staff from entering the hazardous area. According to the warning method, the dangerous area can be isolated, and when a worker approaches the dangerous area or enters the dangerous area, the magnetic adsorption equipment outputs warning information, so that the behavior of the worker entering the dangerous area is prevented, and the problem that personal and property safety is damaged due to the fact that the worker mistakenly enters the dangerous area is avoided.
Fig. 4 shows a magnetic force adsorption apparatus of the present invention. For alerting personnel within a plant, the work area of the plant comprising: the safety buffer area is arranged at the periphery of the dangerous area; the safety buffer area is separated from the dangerous area by an inner warning line; the magnetic force adsorption apparatus 300 includes an identification module 310, a solenoid coil module 320, and a power supply module 330; the method specifically comprises the following steps:
an identification module 310, configured to detect location information of the staff;
the specific method for detecting the position information of the worker by the identification module 310 is as follows: when the identification module detects that the distance between the staff and the outer warning line is less than the preset second threshold value, the identification module starts the positioning function, namely, the position detection is carried out on the staff, and it can be seen that the purpose of the setting is to enable the magnetic adsorption equipment 300 not to work when being far away from a dangerous area, so that the waste of excessive electric quantity is avoided. The manner of setting the second threshold value, the manner of setting the outer guard line, and the manner of setting the safe and quiet area are the same as those in embodiment 1. And the electromagnetic coil module 320 is configured to generate and output a magnetic force adsorption signal when the identification module 310 detects that the worker is in a safety buffer area and the distance between the worker and the inner warning line is smaller than a preset first threshold, and adsorb the worker in the safety buffer area by using magnetic force, so as to achieve the purpose of preventing the worker from entering the dangerous area.
When the working logic of the magnetic force adsorption device 300 is designed, the intensity of the output magnetic force adsorption signal can be adaptively adjusted according to the distance between the staff and the inner warning line. For example, when the distance between the worker and the inner alarm line is smaller, the magnetic force adsorption signal output by the magnetic force adsorption apparatus 300 is stronger. The advantage of doing so is, changes the intensity of magnetic force absorption signal through the distance variation between staff and the interior warning line, makes the staff be close to interior warning line more, and magnetic force is stronger, and finally before strideing across interior warning line, staff's strength is not enough to overcome magnetic force to make the staff stop, if the staff is in safe area, when wanting to withdraw from, keep away from interior warning line then magnetic force is weaker, makes the staff can be independently keep away from the danger zone.
It is to be understood that: the magnetic attraction apparatus 300 should further include a power module 330 coupled to the identification module 310 and the solenoid module 320, respectively, for supplying power to the identification module 310 and the solenoid module 320, respectively.
In a specific implementation of an embodiment of the present invention, the magnetic force adsorption device 300 is specifically a magnetic force adsorption safety shoe. When the structure of the safety shoe is designed specifically, the electromagnetic coil module 320 is located at the heel position of the magnetic adsorption safety shoe, the identification module 310 is located at the toe cap position of the magnetic adsorption safety shoe, and the power supply module 330 is located at the middle part of the magnetic adsorption safety shoe. The electromagnetic coil module is arranged at the position of the heel, so that even if the magnetic force is increased, a worker can only lift the foot, and the falling condition can be avoided.
Through the magnetic adsorption equipment, a dangerous area can be isolated, when a worker approaches the dangerous area, the magnetic adsorption equipment outputs a magnetic adsorption signal, so that the behavior of the worker entering the dangerous area is prevented, and the problem that personal and property safety is damaged due to the fact that the worker mistakenly enters the dangerous area is avoided.
