Description

Technical Field

[0001] This utility model belongs to the field of power warning equipment, and specifically relates to an intelligent power safety warning device. Background Technology

[0002] With the rapid development of the power industry and urban and rural construction, power facilities such as transmission lines and high-voltage equipment are spread throughout urban and rural areas. The dense power facilities often bring certain safety hazards to pedestrians and vehicles passing by. At the same time, in the construction involving power facilities, due to the weak safety awareness of some construction workers, when they violate the regulations, it is very easy to cause power safety accidents, resulting in damage to power facilities and electric shock accidents to people.

[0003] Currently, the common practice in China is to place warning signs near power facilities in urban and rural areas, with warning messages to remind pedestrians, vehicles, and construction workers not to approach. However, this method has limited effectiveness. Besides being easily obscured by dust, making the text illegible, it is also not very intuitive for people approaching power facilities. Electronic power safety warning devices with sound and light alerts have also appeared on the market. These primarily use human body recognition sensors to detect people passing by and then trigger sound and light alarms. However, existing electronic power safety warning devices are usually exposed outdoors and are susceptible to various malfunctions due to long-term environmental impact, resulting in a short lifespan. Furthermore, these devices lack self-diagnostic capabilities, meaning they cannot promptly alert maintenance personnel when malfunctions, rendering their warning function incomplete or even nonexistent, thus failing to provide effective protection for power facilities.

[0004] In view of this, the present invention proposes an intelligent power safety warning device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent power safety warning device to solve the technical problems in the prior art, such as the lack of fault self-diagnosis function in electronic power safety warning devices, the inability to promptly remind relevant operation and maintenance personnel to perform maintenance when the warning device malfunctions, the incomplete or even lost warning function of the warning device, and the inability to effectively protect power facilities.

[0006] To achieve the above objectives, this utility model provides an intelligent power safety warning device, comprising:

[0007] The housing contains an audible and visual alarm module, a battery module, and a controller.

[0011] A wireless communication module and a remote terminal device, wherein the wireless communication module is installed inside the housing and is wirelessly connected to the remote terminal device;

[0012] The power detection module is connected to the battery module, the audible and visual alarm module, and the human body recognition module, respectively. The controller is connected to the power detection module, the battery module, the audible and visual alarm module, the wireless communication module, and the human body recognition module, respectively.

[0013] Preferably, in the above technical solution, the power detection module includes a voltage detection circuit and a current detection circuit. The voltage detection circuit is connected to the battery module, the audible and visual alarm module, and the human body recognition module, respectively, and the current detection circuit is connected to the audible and visual alarm module.

[0014] Preferably, in the above technical solution, the human body recognition module is a radar human body recognition module, and the simulated human body reflector is a corner reflector.

[0015] Preferably, in the above technical solution, the human body recognition module is an ultrasonic human body recognition module, and the simulated human body reflector is a flat metal plate.

[0016] Preferably, in the above technical solution, the sound and light alarm module includes an LED light module, a speaker, and a power amplifier circuit. The power amplifier circuit is connected to the speaker, the voltage detection circuit is connected to both the power amplifier circuit and the LED light module, and the current detection circuit is connected to both the power amplifier circuit and the LED light module.

[0017] Preferably, the above technical solution further includes a temperature detection sensor and a heater. The heater includes a temperature control circuit and a heating element. Both the temperature detection sensor and the temperature control circuit are connected to the controller. The heating element is disposed on the battery module.

[0018] Preferably, the above technical solution further includes a solar panel, which is disposed on the housing and connected to the battery module.

[0019] Compared with existing technologies, this utility model has the following beneficial effects:

[0020] 1. This utility model uses a power detection module to collect the operating current and voltage of the audible and visual alarm module. The controller determines whether the audible and visual alarm module is faulty based on the operating current and voltage status of the audible and visual alarm module. The power detection module detects the operating voltage of the human body recognition module, and the human body recognition module is verified by combining the detection of the simulated human body reflector. The controller determines whether the human body recognition module is faulty. The power detection module collects the voltage of the battery module, and the controller determines whether the power supply of the device is normal. When a module in the device fails, an alarm SMS is sent to the remote terminal device of the maintenance personnel via the wireless communication module. This realizes the fault self-diagnosis and alarm function of the intelligent power safety warning device, enabling maintenance personnel to maintain the faulty intelligent power safety warning device in a timely manner and extend the service life of the device.

[0021] 2. This utility model uses a temperature detection sensor to collect the ambient temperature when the solar panel charges the battery module. When the collected temperature is lower than the user-set threshold, the battery module is heated by a heater to prevent the battery module from failing to charge due to low temperature protection, which would result in insufficient voltage to power the modules at night and prevent the alarm from working.

Detailed Implementation

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0027] refer to Figs. 1-3A smart power safety warning device includes a housing 1, a solar panel 2, a human body recognition module 3, a simulated human body reflector 5, a controller 100, an audible and visual alarm module, a power detection module 103, a temperature detection sensor 105, a heater 106, a wireless communication module 107, a battery module 108, and a remote terminal device.

[0028] The housing 1 has a warning sign that reads "Danger of Electricity". The housing 1 is installed on the electrical facility requiring protection. The controller 100, battery module 108, and audible / visual alarm module are all installed inside the housing 1. The human body recognition module 3 is rotatably mounted inside the housing 1 via a rotating mechanism 4. The audible / visual alarm module includes an LED light module 104, a power amplifier circuit 101, and a speaker 102. The controller 100 is connected to the power amplifier circuit 101, which is connected to the speaker 102. The human body recognition module 3 is connected to the controller 100. When the human body recognition module 3 detects someone approaching the electrical facility, it outputs a switch signal to the controller 100. The controller 100 then drives the power amplifier circuit 101 to operate, discharging the power... The horn 102 driven by circuit 101 issues a voice alarm, stating, "Danger of electricity, do not approach." Simultaneously, the controller 100 drives the LED light module 104 to flash. The solar panel 2 is connected to the battery module 108, which in turn is connected to the controller 100. Specifically, the battery module 108 includes a charging control circuit and a battery. The solar panel 2 is connected to the input of the charging control circuit, and the output of the charging control circuit is connected to both the controller 100 and the battery. Through the charging control circuit, the controller 100 can provide power to both the solar panel 2 and the battery. The solar panel 2 can also charge the battery via the charging control circuit. The controller 100 uses an STC8H4K64TL microcontroller with an internal RTC clock. During nighttime hours, the controller 100 only drives the LED light module 104, causing it to flash and alert people near the electrical facilities to the warning signs on the casing 1, thus avoiding nighttime noise disturbance.

[0029] The power detection module 103 is connected to the power amplifier circuit 101, the LED light module 104, the battery module 108, and the human body recognition module 3. The controller 100 is connected to the power detection module 103. The power detection module 103 includes a voltage detection circuit and a current detection circuit. The voltage detection circuit is connected to the power amplifier circuit 101, the LED light module 104, the battery module 108, and the human body recognition module 3, while the current detection circuit is connected to the power amplifier circuit 101 and the LED light module 104. The voltage detection circuit detects the operating voltage of the power amplifier circuit 101, and the current detection circuit detects the operating current of the power amplifier circuit 101. The controller 100 calculates the output power of the power amplifier circuit 101 when it is working. When the operating voltage or operating current of the power amplifier circuit 101 is greater than the user-set maximum threshold, lower than the minimum threshold, or fluctuates significantly, it indicates that the power amplifier circuit 101 has a fault, such as a short circuit, a loose connection at the input terminal, or component aging, which prevents it from driving the speaker 102 to play voice normally. The voltage detection circuit detects the voltage of the battery module 108, thereby realizing whether the operating voltage of the entire device is normal. The voltage detection circuit detects the operating voltage of the human body recognition module 3. On the one hand, it ensures that the power supply voltage of the human body recognition module 3 is normal. On the other hand, it checks whether there is a short circuit fault in the human body recognition module 3. If there is a short circuit fault, the voltage at the human body recognition module 3 will be much lower than the rated value.

[0030] The first implementation of the human body recognition module 3 is a radar human body recognition module, specifically a WTL580-C01 microwave radar sensing module. The first implementation of the simulated human body reflector 5 is a corner reflector, which simulates a human body and reflects the microwaves emitted by the radar human body recognition module. During the verification of the radar human body recognition module, the rotating mechanism 4 rotates the radar human body recognition module to a set angle, causing the microwave signals emitted by the radar human body recognition module to illuminate the corner reflector and be reflected back to the radar human body recognition module for reception. The controller 100 determines whether the radar human body recognition module's human body detection function is normal by reading the switch signal of the radar human body recognition module. Fig. 2 As shown, the corner reflector used in this embodiment is a metal plate with multiple metal corners. The working principle of the corner reflector reflecting microwave radar is a well-known existing technology, and will not be described in detail in this embodiment.

[0031] The second implementation of the human body recognition module 3 is an ultrasonic human body recognition module, specifically the HC-SR04 ultrasonic module. The second implementation of the simulated human body reflector 5 is a flat metal plate. The flat metal plate simulates the human body and reflects the ultrasonic waves emitted by the ultrasonic human body recognition module. When calibrating the ultrasonic human body recognition module, the rotating mechanism 4 rotates the ultrasonic human body recognition module to a set angle, allowing the ultrasonic wave signal emitted by the ultrasonic human body recognition module to be transmitted to the flat metal plate. The flat metal plate reflects the ultrasonic waves back to the ultrasonic human body recognition module for reception. The controller 100 determines whether the ultrasonic human body recognition module's human body detection function is normal by reading the switch signal of the ultrasonic human body recognition module.

[0032] The heater 106 includes a temperature control circuit and a heating element. The controller 100 is connected to the temperature control circuit, which is in turn connected to the heating element. The heating element is mounted on the battery module 108. The temperature sensor 105 is connected to the controller 100 and is used to collect the ambient temperature. When the temperature sensor 105 detects that the ambient temperature is lower than the user-set threshold, the controller 100 drives the temperature control circuit, which in turn drives the heating element to heat to 25°C, thereby heating the battery module 108. This prevents the battery module 108 from failing to charge due to low-temperature protection and prevents the battery module 108 from failing to supply power to the device at night due to low voltage.

[0033] The wireless communication module 107 is connected to the controller 100, and the remote terminal device is wirelessly connected to the wireless communication module 107. When the controller 100 detects faults in the human body recognition module 3 and the audible and visual alarm module through the power detection module 103 and the simulated human body reflector 5, it sends a fault SMS message to the remote terminal device through the wireless communication module 107. This allows maintenance personnel to perform timely maintenance on the faulty power safety intelligent warning device, extending the device's service life. In this embodiment, the wireless communication module 107 is a GSM module, and the remote terminal device is a mobile phone.
