Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that: like reference numerals or letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
Before the illustration, the application scenario related to the embodiments of the present invention needs to be further described, first, whether the wearing of the safety belt is correct or not is detected, and whether the safety belt is correctly worn is sensed by pressure sensing or according to the distance between the plurality of belt strips of the safety belt. The safety belt is not worn, and firstly, the electronic sensing equipment can alarm, and an alarm signal can remind a wearer or the safety belt is uploaded to a central control room. However, there are two problems, namely, some falling accidents are not equipped with safety belts, but the operators carelessly or too confident mistake causes the operation of not wearing the safety belts; secondly, sometimes the operator does not want to wear the safety belt correctly, but the operator is in a suspended state or the body position of the operator is inconvenient to adjust the safety belt, so that other operators are required to help adjust the wearing. When workers need other workers to help and adjust the safety belt, the concrete vibrator used for on-site construction has huge noise, and the workers often cannot be informed orally that other workers are nearest to remind or help the workers; if the alarm signal is not correctly worn, the alarm signal is transmitted to a central control room of the manager, but even if the alarm signal is uploaded to the central control room, the alarm signal is transmitted to the operators through the safety manager, but the construction of the operators is scattered often, and the safety manager does not know the accurate positions of the operators; yet another way is for the central office to call the operator sending the alarm signal through the intercom, but some construction sites such as the corridor, ventilation shaft, etc. may not be well signaled and a separate signal amplifier is required. In the field operation construction process, the operation is usually performed in each operation area according to a team or a team, so that the technical scheme of the invention is to inform workers who are not wearing the safety belt correctly by linking the team or the workers closest to the area to carry out alarm reminding, and informing the workers to monitor, remind and help the workers in time.
Example 1: as shown in fig. 1, the present embodiment provides a method for monitoring an aerial work safety belt, which includes:
step S1, acquiring an identification number of a safety belt, an operation area number and identity information corresponding to an operator who takes up the safety belt, wherein the identity information is obtained by acquiring face information of the operator through a camera for identity recognition when the safety belt is taken up; adding the identification number of the safety belt with the same operation area number and the identity information of the corresponding operator into a first set; the identification number of the safety belt can be obtained through a series of modes such as bar codes, two-dimensional codes and the like which can be endowed with distinguishing codes, so that quick code scanning identification can be realized, and the number of the operation area can be obtained through the input of a work order system or a manager; the camera is also a common mode for identifying the identity of the operator through face information, for example, a CNN algorithm or an Eigenface algorithm and the like are used for identifying, matching and identifying through the face information of the operator which is input in advance and the face information captured by a safety belt on site.
S2, carrying out networking communication test on the safety belts in the first set until detecting that the communication function of the first set is normal; when the communication function of the first set is detected to be normal, setting the safety belt in the first set to be in a communication dormancy state; the first set can be regarded as operators working in the same working area, so that the operators can carry out networking among safety belts, the networking mode comprises wireless networking modes such as WIFI, mesh or Zigbee, the specific selection can be selected according to requirements, and the ZigBee networking is selected in the embodiment of the invention. In practical tests, the dry battery used by the ZigBee networking mode scheme can be used for more than 6 months, the prior safety belt sends out alarm signals without complex data transmission, namely, the size of transmission bytes is not required to be higher, and the transmission distance can be easily connected in a communication way under the condition of not adding a signal amplifier by adopting the prior ZigBee technology. WIFI and Mesh are two other selectable networking modes, the power consumption of the WIFI networking mode is high, and the Mesh mode can be relatively applied to the scheme.
Step S3, before the operation at high altitude is performed, calibrating the initial height of the safety belt of the first set by an operator, and setting the safety belt of the first set in a communication dormancy state as a communication awakening state and recording the safety belt of the first set as a second set when the operation height of the operator is detected to be greater than a set height threshold value by an air pressure sensor of the safety belt of the first set; the air pressure sensor is calibrated on the ground of the operation area, when a set number of air pressure sensors are calibrated, other air pressure sensors which are not calibrated in the first set are also passively calibrated, so that the situation that operators forget to calibrate the ground reference height is prevented. At present, the accuracy of the measured height of the air pressure sensor can reach 0.1 meter, and when an operator wears a safety belt and marks the ground reference height before entering the high-altitude operation, the height from the ground when the operator wears the safety belt during the mark of the operator needs to be considered.
Step S4, any one safety belt in the second set searches other safety belts in the second set through a communication function, and when the signal intensity between the two safety belts is greater than a set intensity threshold value, the two safety belts are set to be a linkage alarm group; although some operators construct in the same operation area, some safety belts are not connected with each other by a partition wall or a ventilation shaft shielding area, so that each safety belt finds out the own linkage alarm group, only one safety belt sends out a first alarm signal, and the other safety belts passively send out a second alarm signal. The linkage alarm group can be one safety belt and another safety belt, or the linkage alarm group is combined after the signal intensity between the safety belt and the plurality of safety belts is larger than the set intensity threshold value.
And S5, when the first safety belts in the second set are not worn or are worn by mistake and generate first alarm signals, the second safety belts forming the linkage alarm group with the safety belts all send out second alarm signals, and the operators corresponding to the second safety belts inform, remind or help the operators corresponding to the first safety belts to wear the first safety belts correctly. The first alarm signal and the second alarm signal are distinguished, the first alarm signal is used for reminding a user of incorrectly wearing the safety belt, and the second alarm signal is used for reminding a user of incorrectly wearing the safety belt beside the safety belt to be supervised or helped. The specific distinction can be set according to different alarm signal sounds, different lights or different vibrations, and the staff is trained in advance to have the distinguishing capability.
Further, the method further comprises:
detecting the operation height of the safety belt of the first set, and setting the safety belt of the first set in a dormant state to be in a communication awakening state and adding the safety belt into the second set when the operation height is larger than a set height threshold value; and detecting the working height of the safety belt of the second set, and setting the safety belt of the second set in the communication awakening state into the communication dormant state and adding the safety belt into the first set when the working height is lower than the set height threshold value. Only when the safety belt enters the high-altitude operation state, networking communication is carried out, and signals need to be transmitted periodically once the safety belt is communicated, so the safety belt exiting the high-altitude operation state should be timely caused to exit the second set. In the definition of the overhead operation in China, the operation height of the overhead operation refers to the operation of the overhead position where the overhead operation is likely to fall by 2 meters or more.
Further, the method further comprises:
and (3) periodically carrying out communication test between the two safety belts of the linkage alarm group, and releasing the linkage alarm group relation of the two safety belts when the signal intensity between the two safety belts is detected to be lower than the set intensity threshold value, and retesting the signal intensity to generate a new linkage alarm group. The working construction of the worker is often movable, and therefore the linkage alarm group relationship needs to be changed according to the mutual distance varying in real time. In practice, the frequency of the periodic communication test may be set to approximately 10 to 30 s/time, which is appropriate. In communication signal transmission, the signal intensity is generally larger as the mutual distance is smaller, but the signal intensity at certain partition walls or communication blind angles is also poorer, and the linkage alarm is most suitable according to the signal intensity at the moment, because the signal intensity is poor due to the fact that the signal intensity is very close behind the partition walls, and even if the partition walls are informed to monitor or help wear safety belts, the person behind the partition walls cannot see the other person, so that the linkage alarm is not optimal. Two persons with larger signal intensity, though being close to two persons possibly without a partition wall, often have no partition wall obstacle at this time and have wider vision, when a first alarm signal is sent out, the other person can immediately sense a second alarm signal, and immediately get close to or shout for an operator of the first alarm signal, and the operator can supervise and inform or help the operator to wear a correct safety belt.
Further, as shown in fig. 2, the method further includes:
when the first safety belt generates a first alarm signal, measuring the distance between the second safety belt and the first safety belt through the signal intensity between the second safety belt and the first safety belt, and when the distance is not reduced to a set rescue distance threshold value within a set rescue time threshold value and the first alarm signal is not released during the period, searching other safety belts except the second safety belt in the second set by the communication function of the first safety belt and marking the other safety belts as a third safety belt, and sending the first alarm signal to the third safety belt to trigger the third safety belt to generate a second alarm signal and inform, remind or help an operator corresponding to the first safety belt to wear the first safety belt correctly; when the person in the first safety belt does not cancel the first alarm signal to indicate that the safety problem of wearing the safety belt is not corrected, and the worker is not close to the first safety belt in the rescue time, that is, presumes that the second safety belt may not be in-progress reminding or helping, the worker in other safety belts is required to intervene.
Forwarding the first alarm signal to a fourth safety belt with the best signal strength through a communication relay function of the second safety belt or the third safety belt and triggering the fourth safety belt to generate a second alarm signal when the first safety belt is not searched for and connected to the third safety belt at the set connection time threshold value by the communication function or when the first safety belt is successfully connected to the third safety belt and the distance between the third safety belt and the first safety belt is not reduced to the set rescue distance at the set rescue time and the first alarm signal is not released during the set rescue time; and if the first alarm signal cannot be released within the set rescue time, forwarding the first alarm signal to the safety belts of the other second set through the communication relay function of the second safety belt. When the first safety belt is not supervised and assisted by other operators in the signal range, the first alarm signal is always present, and the searched safety belt is triggered to expand the alarm signal notification range by using the communication relay function of the other safety belt. For example, in the present embodiment, the first seatbelt can directly connect the second seatbelt and the third seatbelt, but the first alarm signal of the first seatbelt needs to be transmitted to the fourth seatbelt through the communication relay function.
Further, the method further comprises:
when the safety belts of the second set and other safety belts do not form a linkage alarm group, the linkage alarm group is recorded as a fifth safety belt; when the first alarm signal occurs to the fifth safety belt, starting a GPS or Beidou positioning system of the safety belt in the second set, searching a sixth safety belt closest to the fifth safety belt, triggering the sixth safety belt to generate a second alarm signal, and informing, reminding or helping an operator corresponding to the fifth safety belt to correctly wear the fifth safety belt through the operator corresponding to the sixth safety belt; when the first alarm signal can not be released at the set rescue time, other safety belts which are next closest to the fifth safety belt are sequentially searched and triggered to generate a second alarm signal. However, when the operator performs an independent operation, if he does not wear the safety belt correctly, he needs to find the operator closest to the operator through the positioning system for a long time, and the operator is positioned by the geographical position at the moment, so that the GPS or Beidou positioning function installed on the safety belt is also required to be opened, and therefore, when the first alarm signal occurs, the positioning test distance is opened in sequence, the nearest safety belt or belts are found to send out the second alarm signal, and other operators are notified to supervise or help.
