Description

Technical Field

[0001] The utility model belongs to the technical field of warning equipment, in particular to a voice warning device for maintenance. Background Art

[0002] In modern building and facility management, elevators, as an essential tool for vertical transportation, are crucial for their safe operation. To ensure passenger safety, effective measures must be taken to prevent passengers from misusing elevators when they are not in service, such as during maintenance, inspection, or cleaning. Traditionally, physical barriers such as fences, warning signs, or simple audible alarms have been used to alert people that the elevator is unavailable. However, these methods have some shortcomings:

[0003] Static warning signs may not easily attract people's attention, especially in busy public places or places with a lot of visual information. Simple audio alarms may also be ignored due to environmental noise. Traditional methods cannot adjust the warning content according to actual conditions, nor can they communicate with the monitoring center or other management systems in real time, making it difficult to achieve remote management and instant feedback. Some temporary warning devices require additional time to set up and may not be stable enough and easily moved or damaged, affecting the effectiveness of the warning. Some warning devices may not take energy efficiency issues into consideration, resulting in short battery life. Frequent battery replacement increases maintenance costs and workload.

[0004] To this end, we provide a maintenance voice alarm to solve the above problems. Utility Model Content

[0028] Example

[0029] See also Figures 1-4The present invention is a voice alarm for maintenance, comprising an alarm body 100 and a bracket 200 for mounting and fixing the alarm body 100. The alarm body 100 is fastened and fixed inside the bracket 200. The alarm body 100 comprises a housing 101, an indicator light 102 and a voice prompt area 103 provided on the upper front portion of the housing 101, a heat dissipation area 104 provided on the lower front portion of the housing 101, and a detection control module 105 and a lithium battery 106 built into the housing 101. A speaker 107 is provided correspondingly inside the voice prompt area 103, and the speaker 107 is connected to the microcontroller 105b via a connecting line.

[0030] The detection control module 105 includes a PCB board 105a fixed to the inside of the shell 101, a microcontroller 105b and a radar detection module 105c integrated on the PCB board 105a, and a light switch 105d connected to the microcontroller 105b via internal wires. The radar detection module 105c is installed near the front of the shell 101 and is connected to the microcontroller 105b via wiring. The PCB board 105a also integrates a remote communication module 105e, and the microcontroller 105b establishes an interactive communication link with the external monitoring end via the remote communication module 105e. The radar detection module 105c continuously monitors the surrounding environment and immediately sends a trigger signal to the microcontroller 105b once it detects someone approaching within a set safety distance. After receiving the trigger signal, the microcontroller 105b will quickly start the speaker 107 to issue a pre-recorded voice warning and light up the indicator light 102 to form a visual prompt.

[0031] Specifically, the lithium battery 106 is arranged at the bottom of the shell 101, and the lithium battery 106 corresponds to the position of the heat dissipation area 104. The slots provided in the heat dissipation area 104 can effectively dissipate the heat generated by the lithium battery 106 during operation. The lithium battery 106 is connected to a charging interface 106a and a power switch 106b via internal wires, and the charging interface 106a and the power switch 106b are both embedded in the bottom side of the shell 101. The charging interface 106a is used to charge the lithium battery 106, and the power switch 106b is used to control the connection and disconnection of the power supply circuit of the lithium battery 106. The light switch 105d is embedded in the top of the shell 101. The light switch 105b can directly control the switch of the indicator light 102. In a bright light environment, the prompt effect of the indicator light 102 is weak, and it can be manually lowered and turned off to save power, which helps the lithium battery 106 to continue working.

[0032] Further, the lower part of the bracket 200 is provided in a groove shape, and a buckle is arranged inwardly at the middle position of the upper part of the bracket 200, and the top of the bracket 200 is provided in a curved shape, and the groove-shaped area of the bottom of the bracket 200 is matched with the buckle arranged at the upper part of the bracket 200, so that the voice warning device is limited and installed, and the curved structure arranged at the top of the bracket 200 is helpful for the quick installation of the bracket 200.

[0033] In conclusion, when the elevator is in the abnormal service state (such as maintenance and cleaning), the warning device can effectively remind passengers not to use the elevator, so as to avoid danger.
