Description

Technical Field

[0001] This application belongs to the technical field of safety equipment, and specifically relates to a seat belt status detection device and method. Background Art

[0002] The seat belt is an essential safety equipment for high-altitude construction operations. It can effectively avoid the huge harm caused by falling to the human body in case of an accident. The correct way to use a seat belt is to hang it high and use it low, that is, to hang the seat belt lanyard above the operator, which can reduce the actual impact distance in case of a fall; on the contrary, hanging it low and using it high will increase the actual impact distance in case of a fall, bringing danger. Therefore, the seat belt for high-altitude operations should be hung high and used low, and hanging it low and using it high should be prohibited. Real-time monitoring of whether the seat belt lanyard is in the high-hanging state, and timely discovering and stopping the incorrect hanging method of the seat belt is of great significance for the safety management of the construction site.

[0003] In the existing methods, a multi-sensor method is usually used to monitor the seat belt status. The device has a complex structure. There is usually liquid in the wires or connecting wires, which will hinder the activities of high-altitude operators. In addition, the device manufacturing cost is high, it is easily damaged, and the maintenance workload is large.

[0004] In the existing methods, video surveillance is also used to intelligently judge the seat belt status. However, the corresponding device has problems such as a large number of video surveillance targets and a long distance, and the false alarm rate is extremely high, seriously affecting the actual use. Summary of the Invention

[0047] The present disclosure will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0048] Safety belts are essential safety equipment for high-altitude construction work. They can effectively prevent the great harm to the human body caused by falling in the event of an accident. The correct way to use a safety belt is to hang it high and use it low, that is, to hang the safety belt rope above the operator, which can reduce the actual impact distance when a fall occurs; on the contrary, hanging it low and using it high will increase the actual impact distance when a fall occurs, which brings danger. Therefore, safety belts for high-altitude work should be hung high and used low, and low hanging and high use should be avoided. Real-time monitoring of whether the safety belt rope is in a high hanging state, and timely detection and prevention of incorrect hanging methods of safety belts are of great significance to the safety management of construction sites.

[0049] In the existing methods, a multi-sensor method is usually used to monitor the status of the seat belt. The device has a complex structure and usually has liquid in the wires or connecting wires, which will hinder the activities of high-altitude workers. In addition, the device is expensive to manufacture, is easily damaged, and requires a lot of maintenance.

[0050] The existing method also uses video surveillance to intelligently identify the seat belt status, but the corresponding device has the problem of many video surveillance targets and long distances, and the false alarm rate is extremely high, which seriously affects the actual use.

[0051] This application proposes a seat belt status detection device and method, which uses a simple and easy wireless near-field communication between a directional signal receiving module and a signal generating module or simply determines the height difference between the hook and the waist relative to the ground to detect the seat belt status, solving the problem of inaccurate and complex seat belt status detection.

[0052] Example 1:

[0053] This embodiment provides a seat belt status detection device, such as Figure 1 As shown, it includes: a signal receiving module 9 installed at the position of the seat belt 7 and at least one signal generating module 2;

[0054] The signal generating module 2 is used to emit a detection signal;

[0055] The signal receiving module 9 is used to collect the detection signal and send the detection signal to the main control module;

[0056] The main control module is used to obtain status information of whether the seat belt is used correctly based on the relative position relationship between the detection signal and the seat belt waist belt, and when the status information indicates that the seat belt is not used correctly, an alarm message of incorrect use of the seat belt is issued.

[0057] In a possible specific implementation, as long as the signal generating module and the signal receiving module can perform wireless near-field communication, regardless of what specific devices the signal generating module and the signal receiving module are, they all fall within the scope of protection of this application. The specific implementation process is detailed as follows: When only one signal generating module is used, the signal generating module includes a first signal generating module and is installed at the position of the seat belt hook;

[0058] The first signal generating module is used to transmit a first detection signal;

[0059] The signal receiving module is used to collect the first detection signal. If the height of the first detection signal relative to the ground is lower than the height of the seat belt relative to the ground, then the signal receiving module can detect the first detection signal within the signal receiving range and send the first detection signal to the main control module;

[0060] The main control module is used to judge that the status information is that the seat belt is not used correctly and send out an alarm message for incorrect use of the seat belt when the first detection signal is less than a preset signal threshold.

[0061] The signal generating module uses a first Bluetooth transmitting device or a radio frequency transmitting device; the signal receiving module is a first Bluetooth receiver or a radio frequency receiving device.

[0062] The signal receiving module has a receiving antenna, and the designated surface of the receiving antenna is wrapped with metal or the receiving antenna uses a directional antenna.

[0063] The signal receiving range is the space in the corresponding direction of the surface of the receiving antenna that is not wrapped with a metal shell and can receive the first detection signal, or the space in the designated direction of the directional antenna that receives the first detection signal.

[0064] In this embodiment, traditional seat belts such as Figure 1As shown in the figure, it includes: a seat belt hook 1 (including two types: single hook and double hook), a safety rope 3, a shoulder strap 4, a chest strap 5, a buckle 6, a seat belt waistband 7, and a leg strap 8. In this embodiment, a first signal generating module is installed at the position of the seat belt hook 1. If the seat belt hook 1 is a double hook, then one first signal generating module is hung or tied at each seat belt hook 1; a signal receiving module 9 is installed at the position of the seat belt waistband 7. The signal receiving module 9 has a receiving antenna. When the signal generating module adopts a Bluetooth transmitting device or a radio frequency transmitting device solution, the receiving antenna adopts a special upward-opening metal enclosure or the receiving antenna adopts a directional antenna. In this embodiment, the bottom surface of the signal receiving module 9 is fixed at the position of the seat belt waistband 7. Therefore, the receiving antenna adopts a special upward-opening metal enclosure or the receiving antenna adopts a directional antenna to shield the detection signals coming from below the antenna and only receive the detection signals coming from above the receiving antenna. When the first signal generating module is located above the signal receiving module 9, the detection signals collected by the signal receiving module 9 are significantly higher than when the first signal generating module is located below the signal receiving module 9, so as to judge whether the hanging position of the seat belt hook 1 is above the waistband 7. In specific applications, whether the signal receiving module 9 is a Bluetooth receiver or a radio frequency receiving device, those skilled in the art hope to receive detection signals as comprehensively as possible to improve the efficiency of wireless near-field communication between the first signal generating module and the signal receiving module 9. However, in this embodiment, the detection signals transmitted from a specified direction are intentionally shielded so that the signal receiving module 9 can detect the detection signals within a specified receiving range, and then effectively judge the state of the seat belt, that is, whether it is hung high and used low or hung low and used high. The receiving range is the space where the detection signals can be received in the direction corresponding to the surface of the receiving antenna that is not wrapped by a metal shell, or the space where the detection signals are received in the specified direction of the directional antenna. If the detection signal is detected within the signal receiving range of the signal receiving module 9, and the detection signal is less than a preset signal threshold, at this time, the signal receiving module 9 issues an alarm message to prompt that the seat belt is not used correctly, that is, it is hung low and used high at this time.

[0065] In another possible specific implementation, that is, when the signal generating module adopts a Bluetooth plus barometric altimeter solution, two such signal generating modules are used at this time. The signal generating module includes a second signal generating module and a third signal generating module. The second signal generating module is installed at the position of the seat belt hook, and the third signal generating module is installed at the position of the seat belt waistband. The second signal generating module includes a first barometric altimeter and a second Bluetooth transmitting device connected to the first barometric altimeter, which is used to transmit a second detection signal. The third signal generating module includes a second barometric altimeter, which is used to send the detected third detection signal to the main control module. The signal receiving module is a second Bluetooth receiver, which is used to receive the second detection signal;

[0066] When the height of the second detection signal relative to the ground is lower than the height of the safety belt relative to the ground, the main control module is used to determine that the detected value of the third detection signal is greater than the detected value of the second detection signal. At this time, the status information indicates that the safety belt is not used correctly, and an alarm message for incorrect use of the safety belt is issued.

[0067] In a specific implementation, one barometric altimeter is provided for each of the signal generation module and the signal reception module. The signal generation module transmits the height value of the hook relative to the ground detected via Bluetooth to the signal reception module, and the signal reception module collects the height value of the waist relative to the ground. If the height value of the hook relative to the ground minus the height value of the waist relative to the ground is a positive value, it is determined that the safety belt is in the correct use state of high hanging and low using; if the height value of the hook relative to the ground minus the height value of the waist relative to the ground is a negative value, it is determined that the safety belt is in the incorrect state of low hanging and high using, and the signal reception module issues an alarm message to indicate that the safety belt is not used correctly.

[0068] In a specific implementation, an alarm LED light can be provided on the signal reception module 9. When the safety belt is in the state of low hanging and high using, the alarm LED light on the signal reception module 9 is triggered, and the alarm LED light flashes to issue an alarm, so that the construction workers using the safety belt on site can notice that the safety belt is in the incorrect use state at this time and needs to be adjusted in time. The status detection, time accumulation and alarm of all safety belts are automatically started after entering the designated safety belt status monitoring area without manual intervention; when the device exits the designated area, it is automatically prohibited.

[0069] The safety belt status detection device can be designed with an IP66 protection level and adapted to harsh working conditions: 30 - 60 °C.

[0070] This embodiment provides a safety belt status detection device, which uses the directional near - field communication between the signal generation module 2 installed at the position of the safety belt hook 1 and the signal reception module 9 installed at the position of the safety belt waist 7, or judges the height difference between the hook and the waist relative to the ground to realize the detection of the safety belt status. This device solves the problems of inaccurate and complex safety belt status detection, and has the advantages of low cost, not easy to be damaged, accurate detection and applicability to harsh working conditions.

[0071] Embodiment 2:

[0072] This embodiment provides a safety belt status detection device, as Figure 2 shown, including: a signal reception module 9 installed at the position of the safety belt waist 7, at least one signal generation module 2, a wireless communication module and a monitoring module;

[0073] The signal generation module 2 is used to transmit a detection signal;

[0074] The signal receiving module 9 is used to collect the detection signal, collect the detection signal, and send the detection signal to the main control module;

[0075] The main control module is used to obtain the status information of whether the seat belt is correctly used based on the relative position relationship between the detection signal and the seat belt webbing. When the status information indicates that the seat belt is not correctly used, an alarm message for incorrect use of the seat belt is issued;

[0076] The wireless communication module is used to wirelessly send the detection signal collected by the signal receiving module to the base station, and the base station sends the detection signal to the monitoring module;

[0077] The monitoring module is used to set the seat belt status monitoring area, so that the signal receiving module in the seat belt status monitoring area can issue an alarm message, and display the user positioning information of the seat belt in the form of a positioning graph.

[0078] In this embodiment, a seat belt status detection device not only includes a signal generation module 2 and a signal receiving module 9, but also includes a wireless communication module and a monitoring module. The wireless communication module can transmit the detection signal collected by the signal receiving module 9 to the base station in real time. The signal receiving module 9 is within a range of 1 km radius from the base station. The base station forwards the received detection signal to the monitoring module. In this embodiment, the monitoring module can be a computer with a monitoring system, and this embodiment can support real-time communication and positioning of more than a thousand signal receiving modules 9.

[0079] In this embodiment, the monitoring module can delimit the seat belt status monitoring area through the monitoring system software, so that the signal receiving module 9 in the seat belt status monitoring area can issue an alarm message and can implement the corresponding statistical function. The signal receiving module 9 not in the seat belt status monitoring area does not issue an alarm and does not perform the corresponding statistics. When the signal receiving module 9 enters the seat belt status monitoring area, timing starts to accumulate the duration of incorrect use of the seat belt. If the duration exceeds the preset duration threshold, an alarm for timeout of incorrect use of the seat belt is issued.

[0080] Similarly, the monitoring module is also used to accumulate the ratio of the duration of incorrect use of the seat belt to the time of entering the seat belt status monitoring area. If the time ratio is less than or equal to the preset ratio threshold, a reminder message for exceeding the limit ratio of incorrect use of the seat belt is issued. The monitoring module is also used to count the number of times of incorrect use of the seat belt. If the number of times is greater than the preset number threshold, a reminder message for exceeding the limit number of incorrect use of the seat belt is issued. The monitoring module is also used to count the number of times of incorrect use of the seat belt. If the number of times is greater than the preset number threshold, a reminder message for exceeding the limit number of incorrect use of the seat belt is issued.

[0081] In a specific implementation, the monitoring module can be implemented by a computer with corresponding software installed to achieve the monitoring function. The reminder information sent by it can be sent by the software to pop up a prompt box to give an alarm for incorrect use or timeout of the safety belt, or to prompt information such as exceeding the limit number of times or the cumulative proportion.

[0082] The above statistical function enables the management personnel to master the safety belt usage information at the construction site in real time. The management personnel can manage the personnel using the safety belt according to the proportion ranking. If the proportion exceeds the set threshold, it can be considered qualified, otherwise it is unqualified.

[0083] This embodiment provides a safety belt status detection device, which can wirelessly send the detection signal collected by the signal receiving module 9 to the monitoring module through the wireless communication module; the monitoring module delimits the safety belt status monitoring area, so that the signal receiving module 9 in the safety belt status monitoring area can send out an alarm message, and can count the cumulative duration, number of times and time proportion of incorrect use of the safety belt. This device enables the management personnel to master the safety belt usage information at the construction site in real time, and can monitor the status of more than a thousand safety belts at the same time.
