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 may 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. 2. 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 dangerous area refers to a station or an equipment installation position with a high risk factor inside a factory, and an inner warning line is firstly defined at the periphery of the dangerous area and separates the dangerous 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:
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 warning device 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 to have magnetic force to adsorb warning device staff to 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.
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 can be sent to the working personnel when the working personnel enter 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 invention sends the active warning information to the staff, and has the advantage that the active warning information cannot be ignored by the staff even in a noisy and chaotic environment compared with the traditional passive warning information (sound and light warning information).
Through the warning method, the dangerous area can be isolated, when a worker approaches the dangerous area, the warning system outputs the touch warning information, so that the behavior of the worker entering 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 an optimized embodiment, the warning system may specifically include: magnetic force of dress on the staff adsorbs warning device, for example dress in the magnetic force of workman on the staff foot adsorbs safety shoes. 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 warning device 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 warning device sends 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 adsorption warning device can adjust the intensity of the output magnetic adsorption signal according to the distance between the worker and the inner warning line, and if the worker is closer to the inner warning line, the output magnetic adsorption signal is stronger.
In a specific embodiment, the magnetic attraction warning device may be a magnetic attraction safety shoe. The magnetic force adsorption safety shoe specifically comprises: the device comprises an identification module, an electromagnetic coil module and a power supply module. The power module is used for supplying power to the identification module and the battery coil module. The identification module is used for detecting the position information of the staff; and the electromagnetic coil module is used for generating a magnetic force adsorption signal and outputting the magnetic force adsorption signal when the identification module detects that the worker is in a safety buffer area and the distance between the worker and the inner warning line is less than a preset first threshold value, and the worker is adsorbed in the safety buffer area by utilizing magnetic force so as to achieve the purpose of preventing the worker from entering the dangerous area.
When the working logic of the safety shoe is designed, the intensity of the output magnetic adsorption signal can be adaptively adjusted according to the distance between the worker and the inner warning line. For example, when the distance between the worker and the inner guard line is smaller, the magnetic adsorption signal output by the magnetic adsorption safety shoe 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.
In addition, when the structure of the safety shoe is designed specifically, the electromagnetic coil module can be located at the heel position of the magnetic adsorption safety shoe, the identification module can be located at the toe cap position of the magnetic adsorption safety shoe, and the power supply module can be 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.
It can be understood that the warning system may further include, in addition to the magnetic attraction warning device: a wearable vest; this wearable undershirt can be when magnetic force adsorbs warning device output magnetic force and adsorb the signal, synchronous output vibration signal or weak current signal to send warning information to the staff. When the advantage of design like this, adsorb signal and vibration signal or weak current signal through output magnetic force, can reach dual suggestion staff's purpose, further ensure staff's personal safety.
The second point to be noted is that the warning system may include a passive warning device in addition to the first, second or third output tactile warning signal device. The passive warning device can be used for generating and outputting a passive warning signal when detecting that the distance between the staff and the outer warning line is smaller than a preset second threshold value. The passive warning signal includes: the sound signal or image signal, the sound signal or image signal emitting device is sound and light alarm device and image monitoring alarm device. The sound and light alarm device can be a warning lamp and a buzzer, and is arranged around the outer warning line. When the distance between the working personnel and the outer warning line is smaller than a preset second threshold value, the warning lamp and the buzzer send out sound-light alarm signals to send out sound-light alarm information to the working personnel, the sound-light alarm information can send out passive warning early warning to the working personnel to remind the working personnel to enter a dangerous area, and the working personnel are prevented from entering the inside of the safe buffer area by mistake under the careless condition.
The design is that the warning system comprises visual and auditory warnings prompted by light and a buzzer, and can prompt workers through visual/auditory passive warning means and the like when the workers do not enter a safety buffer area; after the workers enter the safety buffer area, active intervention means such as sending out a touch warning signal and the like can be used for effectively and actively retaining the workers neglecting the visual/auditory warning entering the safety buffer area in the safety buffer area, so that the workers are actively prevented from entering a dangerous area to cause accidents and influence production work.

In an optional mode, the magnetic adsorption safety shoe outputs the magnetic adsorption signal to prevent the worker from entering the dangerous area, and specifically includes:
if the distance between the worker and the inner warning line is smaller, the magnetic adsorption signal output by the magnetic adsorption safety shoe is stronger.
It can be seen that the distance between the worker and the inner warning line changes to change the intensity of the magnetic adsorption signal, so that the closer the worker is to the inner warning line, the stronger the magnetic force is, and finally before crossing the inner warning line, the force of the worker is not enough to overcome the magnetic force, so that the worker stops.
