During operation on an iron tower, when a hook of a first protector, a hook of a second protector and a hook of a falling protector on a safety belt of an operator are all hung on the iron tower, the operator is in a safe state at the moment, and the hook of the first protector, the hook of the second protector and the hook of the falling protector are communicated with the iron tower. At the moment, a current generator outputs current to a hook of a first protector, a hook of a second protector and a hook of a falling protector, and a control module judges whether current exists in a first current detection module, a second current detection module and a third current detection module or not, so that it is judged that iron tower operation of operators is conducted according to specifications. Therefore, the safety risk is reduced.

Description

Technical Field

[0001] This invention relates to the field of power maintenance technology and is a tower operation early warning system. Background Technology

[0002] Currently, in tower work, the safety belt protection system mainly relies on a structure of "one safety belt, two safety belts, plus a fall arrestor / self-locking device," which has the following defects during operation: First, there is no real-time monitoring of the protection status. The existing devices rely solely on manual inspection of the connection status and cannot automatically determine whether the connection to the tower is "effective". Hidden risks such as "half-attached hooks" or "not properly attached" often occur, and there is no warning of overdue protection failure (e.g., no reattachment if single protection operation exceeds 5 seconds).

[0003] Second, the violation of "high hanging and low use" is difficult to control due to the lack of posture detection methods. Workers choose "low hanging and high use" (hanging point below waist level) for ease of operation, resulting in insufficient buffer distance when falling, doubling the risk factor. Moreover, existing technology cannot identify and stop this violation in real time.

[0004] Third, there is no warning when the safety belt is not used. When the safety belt hook hangs naturally (without being attached to any anchor point), there is no warning mechanism and the safety officer has to supervise it visually. In high towers and complex environments, blind spots in supervision are likely to occur, which may lead to accidents where the safety belt is not used. Summary of the Invention

[0005] This invention provides a tower operation early warning system that overcomes the shortcomings of the prior art and can effectively solve the problem that the safety belt wearing status cannot be identified in real time during existing tower operations.

[0006] The technical solution of the present invention is achieved through the following measures: a tower operation early warning system, comprising a safety belt, a first current detection module, a second current detection module, a current generator, a control module, and an alarm module. A first protector and a second protector are fixedly connected at intervals on the safety belt. The first current detection module, the second current detection module, the current generator, the control module, and the alarm module are installed on the waist belt of the safety belt. The hooks of the first protector and the second protector are electrically connected to the first current detection module and the second current detection module, respectively. Both the first current detection module and the second current detection module are electrically connected to the current generator. Both the current generator and the alarm module are electrically connected to the control module.

[0007] The following are further optimizations and / or improvements to the above-mentioned technical solution: The first current detection module, the second current detection module, and the third current detection module mentioned above can all be current sensing resistors.

[0008] An attitude detection module can be installed on the hook of the first protector and the hook of the second protector. The attitude detection module is electrically connected to the control module.

[0009] The aforementioned attitude detection module can be a tilt sensor.

[0010] The above may also include a timing module, which is connected to the control module.

[0011] A fall arrestor can be fixedly connected to the rear of the aforementioned safety belt. A third current detection module is installed on the waist belt of the safety belt. The hook of the fall arrestor is electrically connected to the third current detection module, and the third current detection module is electrically connected to the current generator.

[0012] This invention has a reasonable and compact structure and is easy to use. When working on a steel tower, the worker is in a safe state when the hooks of the first safety device, the second safety device, and the fall arrestor on the worker's safety belt are all attached to the tower. Since the hooks of the first safety device, the second safety device, and the fall arrestor are closed after being attached to the tower, they are electrically connected to the tower. At this time, the current generator outputs current to the hooks of the first safety device, the second safety device, and the fall arrestor, respectively. Current flows through the first current detection module, the second current detection module, and the third current detection module. The control module determines whether there is current in the first current detection module, the second current detection module, and the third current detection module, thereby determining whether the worker's tower work is being carried out according to regulations. The control module determines whether the worker's tower work is being carried out according to regulations based on whether there is current in the first current detection module, the second current detection module, and the third current detection module.

[0013] When any of the hooks of the first protector, the second protector, or the fall arrestor is not hung according to specifications, two of these hooks will be electrically connected to the tower. The control module will detect current in one of the three current detection modules. Conversely, when two or all of these hooks are missing, they will not be electrically connected to the tower. The control module will detect no current in any of these three current detection modules, determining a safety hazard for the operator. The control module will then send a signal to the alarm module, which will issue an alarm, prompting the operator to connect the hooks of the first protector, the second protector, and the fall arrestor according to specifications. This reduces safety risks, meets daily tower operation requirements, and significantly improves operational safety and compliance. Attached Figure Description

[0014] Appendix Figure 1This is a schematic diagram of the main view structure when used in Embodiments 1 to 6 of the present invention.

[0015] Appendix Figure 2 These are schematic diagrams of the circuit structures of embodiments one through six of the present invention.

[0016] The codes in the attached diagram are as follows: 1 for safety belt, 2 for first protector, 3 for second protector, 4 for fall arrestor, 5 for attitude detection module, and 6 for tower. Detailed Implementation

[0017] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0018] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0019] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1 , 2 As shown, the tower operation early warning system includes a safety belt 1, a first current detection module, a second current detection module, a current generator, a control module, and an alarm module. A first protector 2 and a second protector 3 are fixedly connected at intervals on the safety belt 1. The first current detection module, the second current detection module, the current generator, the control module, and the alarm module are installed on the waist belt of the safety belt 1. The hooks of the first protector 2 and the second protector 3 are electrically connected to the first current detection module and the second current detection module, respectively. Both the first current detection module and the second current detection module are electrically connected to the current generator. Both the current generator and the alarm module are electrically connected to the control module.

[0020] An insulating box is installed on the waist belt of safety belt 1. Inside the insulating box, a first current detection module, a second current detection module, a current generator, a control module, and an alarm module are installed at intervals. The hooks of the first protector 2 and the second protector 3 are electrically connected to the first current detection module, the second current detection module, and the third current detection module, respectively. The first protector 2 and the second protector 3 are both existing technologies. The control module is an existing STM32F103 microcontroller. The current generator is an existing technology, such as the AD590 micro-current generator or the SG-004A multi-functional signal generator. The alarm module is an existing technology, such as an audible and visual alarm. The alarm module can also be composed of a buzzer (120 dB) of model SFM-27 and a red LED with a wavelength of 620 to 630 nm (visible red light within 50 meters).

[0021] When climbing tower 6, the worker is in a safe state when both the hooks of the first protector 2 and the second protector 3 on the worker's safety harness 1 are hooked onto tower 6. Since the hooks of the first protector 2 and the second protector 3 are closed after being hooked onto tower 6, they are electrically connected to tower 6. At this time, the current generator outputs current to the hooks of the first protector 2 and the second protector 3 respectively. Current flows through both the first current detection module and the second current detection module. The control module determines whether there is current in the first current detection module and the second current detection module, thus determining whether the worker's operation on tower 6 is in accordance with regulations. The control module judges whether the worker's operation on tower 6 is in accordance with regulations based on whether there is current in the first current detection module and the second current detection module.

[0022] When either the hook of the first protector 2 or the hook of the second protector 3 is not suspended according to the specifications, the hooks of the first protector 2 and the second protector 3 cannot conduct electricity with the tower 6. The control module will detect that there is no current in the first current detection module and the second current detection module. The control module will determine that there is a safety hazard for the operator and send a signal to the alarm module. After receiving the signal, the alarm module will issue an alarm message, prompting the operator to connect the hooks of the first protector 2 and the second protector 3 according to the specifications, thereby reducing safety risks, meeting the daily operation requirements of the tower 6, and greatly improving the safety and compliance of the operation.

[0023] The above-mentioned tower operation early warning system can be further optimized and / or improved according to actual needs: Example 2: As an optimization of the above examples, as shown in the appendix. Figure 2 As shown, the first current detection module, the second current detection module, and the third current detection module are all current sensing resistors.

[0024] According to the requirements, during the operation on tower 6, only three of the hooks of the first protector 2, the second protector 3, and the fall arrestor 4 are in a safe state when they are attached to tower 6. The rest are in an unsafe state, which poses a safety hazard. At this time, the control module will send a signal to the alarm module, and the alarm module will issue an alarm message to remind the operators to operate in accordance with the specifications.

[0025] When the hooks of the first protector 2, the second protector 3, and the fall arrestor 4 are all hooked onto the iron tower 6 and closed, the hooks of the first protector 2, the second protector 3, and the fall arrestor 4 are interconnected with the iron tower 6. The current generator outputs current to the hooks of the first protector 2, the second protector 3, and the fall arrestor 4 respectively. The first current detection module, the second current detection module, and the third current detection module will have current. The control module will collect the current from the first current detection module, the second current detection module, and the third current detection module, thereby determining that the operator's work on the iron tower 6 is carried out in accordance with the specifications.

[0026] When the hooks of the first protector 2 and the fall arrestor 4 are both attached to the tower 6 and the hook of the second protector 3 is not attached to the tower 6, the hooks of the first protector 2 and the fall arrestor 4 are connected through the tower 6. The hooks of the first protector 2 and the fall arrestor 4 are respectively connected to the first current detection module and the third current detection module. In this way, the current generator, the first current detection module, the hook of the first protector 2, the tower 6, the hook of the fall arrestor 4 and the third current detection module are connected to form a circuit. There is current flowing through the first current detection module and the third current detection module. The control module determines that there is current in the first current detection module and the third current detection module. At this time, the control module determines that the hooks of the first protector 2, the second protector 3 and the fall arrestor 4 of the safety belt 1 are in a half-attached state, that is, one of the hooks of the first protector 2 and the second protector 3 (the hook of the second protector 3) is not suspended according to the specifications.

[0027] Similarly, when the hooks of the second protector 3 and the fall arrestor 4 are both attached to the tower 6 and the hook of the first protector 2 is not attached to the tower 6, the current generator, the second current detection module, the hook of the second protector 3, the tower 6, the hook of the fall arrestor 4, and the third current detection module are connected to form a circuit. There is current in the second current detection module and the third current detection module. At this time, the control module determines that the hooks of the first protector 2, the second protector 3, and the fall arrestor 4 of the safety belt 1 are in a half-attached state, that is, one of the hooks of the first protector 2 and the second protector 3 (the hook of the first protector 2) is not suspended according to the specifications.

[0028] When the hooks of the first protector 2 and the second protector 3 are both attached to the tower 6 and the hook of the fall arrestor 4 is not attached to the tower 6, the current generator, the first current detection module, the hook of the first protector 2, the tower 6, the hook of the second protector 3, and the second current detection module are connected to form a circuit. There is current in the first current detection module and the second current detection module. At this time, the control module determines that the hooks of the first protector 2, the hook of the second protector 3, and the fall arrestor 4 of the safety belt 1 are in a state of disabling protection, that is, the hook of the fall arrestor 4 is not suspended according to the specifications.

[0029] When only one of the hooks of the first protector 2, the second protector 3, or the fall arrestor 4 is attached to the tower 6, the current generator, the first current detection module, the hooks of the first protector 2, the second current detection module, the hooks of the second protector 3, the fall arrestor 4, the third current detection module, and the tower 6 cannot form a circuit. There is no current in the first, second, and third current detection modules. At this time, the control module determines that the hooks of the first protector 2, the second protector 3, and the fall arrestor 4 of the safety belt 1 are in a disabled state, that is, only one of the hooks of the first protector 2, the second protector 3, and the fall arrestor 4 is in a suspended state, and the other two are not suspended according to the specifications.

[0030] Example 3: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2 As shown, both the hook of the first protector 2 and the hook of the second protector 3 are equipped with attitude detection modules 5, which are electrically connected to the control module.

[0031] During use, this setup allows for real-time monitoring of the hook positions of the first protector 2 and the second protector 3, ensuring standardized operations and reducing safety risks during climbing.

[0032] Example 4: As an optimization of the above example, the attitude detection module 5 is a tilt sensor.

[0033] Based on the requirements, the tilt sensor is a known existing technology, such as the MPU6050 dual-axis tilt sensor (accuracy ±0.3 degrees). This allows for real-time monitoring of the hook posture on the hooks of the first protector 2 and the second protector 3, thus detecting whether the hook postures of the hooks of the first protector 2 and the second protector 3 meet the specifications.

[0034] When the angle between the hook of the first protector 2, the hook of the second protector 3 and the horizontal plane is greater than 85 degrees and less than or equal to 90 degrees, the hooks on the first protector 2 and the hooks on the second protector 3 are in a vertically hanging state, and the hooks on the first protector 2 and the hooks on the second protector 3 are not suspended.

[0035] When the angle between the hook of the first protector 2, the hook of the second protector 3 and the horizontal plane is greater than or equal to 0 degrees and less than 30 degrees, the hook of the first protector 2 and the hook of the second protector 3 are in a low-hanging, high-use state. Such hooks of the first protector 2 and the second protector 3 are invalid and do not meet the specifications. After the control module sends a signal to the alarm module, the alarm module will issue an audible and visual alarm (intermittent buzzer sound + slow flashing red LED).

[0036] When the angle between the hook of the first protector 2 and the hook of the second protector 3 and the horizontal plane is greater than or equal to 30 degrees and less than or equal to 85 degrees, the hook of the first protector 2 and the hook of the second protector 3 are in a downward tilting state. At this time, the hooks on the hooks of the first protector 2 and the hooks of the second protector 3 are effectively suspended, which is in accordance with the specification (high hanging, low use).

[0037] When climbing tower 6, if the hook of the first protector 2 is attached to the upper ladder (the angle between the hook of the first protector 2 and the horizontal plane is 45 degrees, and the circuit is closed), and the hook of the second protector 3 is attached to the adjacent lower ladder (the angle between the hook of the second protector 3 and the horizontal plane is 60 degrees, and the circuit is closed), then the hooks of the first protector 2 and the second protector 3 are effectively suspended, meaning there are two valid safety signals. The control module determines that the climbing operation is safe. If the hook of the second protector 3 is removed, only one valid safety signal remains (the suspension status of the hook of the first protector 2). The control module identifies the danger of the climbing operation, and the alarm module issues an alarm (a long alarm sound and a fast red flashing light). At this time, the vibration motor, which is fixed to the inside of the safety helmet with Velcro, can also be electrically connected to the control module. In this way, the control module can also drive the vibration motor to work, thereby reminding the workers to operate in accordance with regulations and eliminating safety hazards.

[0038] Example 5: As an optimization of the above examples, as shown in the appendix. Figure 2 As shown, it also includes a timing module, which is connected to the control module.

[0039] Based on the requirements, the timing module utilizes existing known technology, such as a timing chip of model number [model number missing]. When climbing tower 6, if the hook of the first protector 2 is attached to the upper ladder (the angle between the hook of the first protector 2 and the horizontal plane is 45°, and the circuit is closed), and the hook of the second protector 3 is attached to the adjacent lower ladder (the angle between the hook of the second protector 3 and the horizontal plane is 60°, and the circuit is closed), then the hooks of the first protector 2 and the second protector 3 are effectively suspended, providing two valid safety signals. The control module checks every 100ms to determine whether the operation of climbing tower 6 is safe. If the hook of the second protector 3 is removed, only one valid safety signal (the suspension status of the hook of the first protector 2) is generated, indicating a loss of protection. When the hook of the second protector 3 is removed, the timing module starts timing. If it is not reattached within 5 seconds, the control module identifies a danger in the climbing operation, and the alarm module issues an alarm (a continuous buzzer sound + a rapidly flashing red LED + continuous vibration of the vibration motor inside the safety helmet), thereby reminding the operator to perform the operation correctly and eliminating potential safety hazards.

[0040] If the angle between the tilt sensors on the hooks of the first protector 2 and the second protector 3 is between 85° and 90° for 3 seconds, an "unused warning" will be sent first. If no action is taken within 1 second, the warning will be upgraded to a failure alarm.

[0041] Example 6: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2 As shown, a fall arrestor 4 is fixedly connected to the rear of the safety belt 1. A third current detection module is installed on the waist belt of the safety belt 1. The hook of the fall arrestor 4 is electrically connected to the third current detection module, and the third current detection module is electrically connected to the current generator.

[0042] The safety belt 1 has an insulating box installed on its waist belt. Inside the insulating box, a first current detection module, a second current detection module, a third current detection module, a current generator, a control module, and an alarm module are installed at intervals. The fall arrestor 4 is a known technology, such as the Mais fall arrestor. The fall arrestor 4 contains a tension sensor of model LCX-102 with a range of 0 to 500 kg and a contact sensor of model TTP223 with a tension ≥ 50 N. When the contact sensor is on, the fall arrestor 4 is in a locked state.

[0043] When working on tower 6, the worker is in a safe state when the hooks of the first protector 2, the second protector 3, and the fall arrestor 4 on the worker's safety belt 1 are all attached to tower 6. Since these hooks are closed after being attached to tower 6, they are electrically connected to tower 6. At this time, the current generator outputs current to the hooks of the first protector 2, the second protector 3, and the fall arrestor 4 respectively. Current flows through the first current detection module, the second current detection module, and the third current detection module. The control module determines whether there is current in the first current detection module, the second current detection module, and the third current detection module, thus determining whether the worker's operation on tower 6 is in accordance with regulations. The control module judges whether the worker's operation on tower 6 is in accordance with regulations based on the presence of current in the first current detection module, the second current detection module, and the third current detection module.

[0044] When any one of the hooks of the first protector 2, the second protector 3, or the fall arrestor 4 is not suspended according to specifications, two of these hooks will be electrically connected to the tower 6. The control module will detect that one of the first, second, or third current detection modules is carrying current. When two or all of the hooks of the first protector 2, the second protector 3, or the fall arrestor 4 are missing, these hooks will not be electrically connected to the tower 6. The control module will detect that none of the first, second, or third current detection modules are carrying current. The control module determines that there is a safety hazard for the operator and sends a signal to the alarm module. Upon receiving the signal, the alarm module issues an alarm message, prompting the operator to connect the hooks of the first protector 2, the second protector 3, and the fall arrestor 4 according to specifications. This reduces safety risks, meets the daily operating requirements of the tower 6, and significantly improves operational safety and compliance.

[0045] The tower operation early warning system of this application automatically monitors the number of devices effectively connected to the tower 6 within 5 seconds, ensuring that at least 2 are in a protected state, preventing single-protection or unprotected operation. It identifies the hanging point height in real time through attitude sensors, immediately reminds users of violations, enforces standardized working posture, eliminates "half-hanging" and "virtual hanging", reduces reliance on manual labor, lowers the risk of falls, automatically determines the hanging status of the hook, and issues an early warning if there is no movement within 3 seconds. It eliminates blind spots in the supervision of high towers and complex environments, avoids human negligence, and is suitable for outdoor high voltage and harsh working conditions of the tower 6.

[0046] The above technical features constitute various embodiments of the present invention, which have strong adaptability and optimal implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the requirements of different situations.
