Description

Technical Field

[0001] The utility model belongs to the technical field of limited space operations, and in particular relates to a management system for wearing safety helmets of workers in limited space. Background Art

[0002] In recent years, the number of demands for confined space operations has been rising year by year, and the difficulty of personal safety management has increased accordingly. Confined space operations are more dangerous, and the working environment has insufficient light, poor natural ventilation, and the risk of falling objects. In terms of safety protection, hard hats are indispensable, and workers usually wear hard hats to protect their own safety. At present, there is no professional hard hat wearing protection system for workers in confined space operations. It is more constrained by rules and regulations. Sometimes workers do not fully comply with safety management regulations. For example, if they do not wear hard hats, they wear them correctly when entering the working area, but frequently take off the hard hats during the operation, which will cause the hard hats to lose their protective significance, thereby increasing safety hazards.

[0003] There are some helmet protection equipment on the market, which are mainly divided into the following two methods: The first is a helmet wearing detection method based on computer vision, which uses a camera to capture whether the operator is wearing the helmet normally. This solution can observe the wearing situation of the operator more intuitively. However, this method can only be used in some well-lit environments, and the detection effect is accurate only when the operator remains stationary. In the field of limited space working environment, due to factors such as light, this method is difficult to produce good detection results. The second is to use sensors for detection, usually using infrared and light-sensing detection chips to detect whether it is worn. This method has low cost and mature technology. This method is not affected by the environment, but only has the function of detecting wearing, with poor functions, not intelligent enough, unable to monitor the operation in real time, and lacks management functions. For this reason, we propose a limited space worker helmet wearing management system. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] like Figure 1 As shown, a helmet wearing management system for workers in confined spaces provided by an embodiment of the utility model includes a helmet monitoring hardware platform 01 and a management terminal software platform 02, wherein the helmet monitoring hardware platform 01 and the management terminal software platform 02 communicate with each other using LoRa;

[0027] The helmet monitoring hardware platform 01 includes:

[0028] The main control part 011 is used to realize data collection;

[0029] The power supply part 012 is powered by a lithium battery with an operating voltage of 3.3V. The hard hat monitoring hardware platform 01 has a low power consumption mode;

[0030] Function detection part 013, including:

[0031] Wearing detection module 0131, the wearing detection module 0131 uses a pressure sensor for detection; when the operator is not wearing a helmet, the pressure sensor outputs a low level because it does not feel the pressure, and the system prompts an alarm after recognition; when it is detected that the operator is wearing a helmet, the pressure sensor feels the pressure and outputs a high level, and the system recognizes that the helmet is worn;

[0032] Height detection module 0132, the height detection module 0132 uses a height sensor for detection; when the height change within 10 seconds is greater than the threshold value of 1.70M, it means that the operator has an accident, and the system will prompt an alarm after identification;

[0033] The stationary detection module 0133 uses a gyroscope for detection; if the gyroscope data does not change within 1 minute, it means that an accident has occurred to the operator, and the system will prompt an alarm after identification.

[0034] The interaction and alarm part 014 includes a voice alarm module 0141, a light alarm module 0142 and a vibration alarm module 0143; when a user violates a rule or an abnormal situation occurs, the operator manually closes the safety helmet monitoring hardware platform 01, plays abnormal content through voice, and flashes lights and vibrations to remind other personnel in the working area that they need help.

[0035] The management terminal software platform 02 includes:

[0036] The personnel information management module 021 is used to manage personnel information; the information of personnel wearing safety helmets can be added, deleted, modified, and searched, so that safety helmets are used by specific people and personal information can be displayed at any time.

[0037] Information display module 022, used to display personnel information, personnel height and gyroscope data in real time;

[0038] The alarm module 023 is used to alarm for hat-taking behavior, abnormal height and abnormal stillness and record the alarm data.

[0039] like Figure 1 As shown, as a preferred embodiment of the utility model, the main control part 011 adopts the embedded APM32E103RET6 as the control chip to realize the data collection of the pressure sensor, the height sensor and the gyroscope and the communication with the management terminal software platform 02.

[0040] like Figure 2 As shown, a method for managing the wearing of safety helmets for workers in confined spaces provided by an embodiment of the utility model includes the following steps:

[0041] Step 1: Power on the system, and the helmet monitoring hardware platform 01 waits for the management terminal software platform 02 to add hardware equipment and operator information;

[0042] Step 2: After the management terminal software platform 02 inputs the personnel information and sends the permission to work command, the hard hat monitoring hardware platform 01 starts working;

[0043] Step 3: The helmet monitoring hardware platform 01 performs wearing detection, height detection and stationary detection, and reports data to the management terminal software platform 02 in real time;

[0044] Step 4: When an abnormal situation occurs, the helmet monitoring hardware platform 01 issues a voice, light and vibration alarm, and reports the alarm type and the personnel information to the management terminal software platform 02, which records the alarm and sends a stop operation instruction at the same time;

[0045] Step 5: After resolving the abnormal situation, the management terminal software platform 02 sends a continue operation instruction or a job completion instruction.

[0046] The working principle of the utility model is:

[0047] The utility model embeds a helmet monitoring hardware platform 01 inside the helmet, and detects the wearing status in real time through the built-in pressure sensor. When the operator takes off the helmet and manually closes the helmet monitoring hardware platform 01, the helmet monitoring hardware platform 01 sends out voice, light and vibration alarms and reports to the management terminal software platform 02. The management terminal software platform 02 can record the operator's behavior. At the same time, the helmet monitoring hardware platform 01 has a built-in height sensor and gyroscope. When an abnormal height is detected in a short time or a long period of stillness is an emergency, it will immediately upload the platform alarm to ensure the safety of the operator.

[0048] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
