Description

Technical Field

[0001] The utility model relates to the technical field of high-speed train set manufacturing, in particular to a low-voltage electricity warning device for railway vehicles. Background Art

[0002] During the debugging stage of a single vehicle or a whole train, railway vehicles, whether they are new vehicles, maintenance vehicles or urban rail vehicles, need to undergo low-voltage tests. When the vehicle is delivering low-voltage electricity, the external DC110V power supply on the ground is connected to the vehicle battery box or the low-voltage box at the end of the vehicle to provide the vehicle with a continuous low-voltage power supply to ensure the normal progress of the test. At this time, the cover of the battery box or the low-voltage box at the end of the vehicle needs to be opened to deliver the external DC110V power supply to the interior of the vehicle. At this time, because the cover is open, the internal live devices and their circuits are completely exposed to the outside, and people are prone to accidentally touch and cause electric shock accidents. The previous method was to stick paper tape or protective plates on the battery box or the low-voltage box at the end of the vehicle to make a reminder; or to set up a special person to monitor here. After a period of time, the paper tape or protective plate is easy to fall off and no longer serves as a reminder. By setting up a special person to monitor here to remind the passing personnel, someone needs to monitor all the time, which is time-consuming and labor-intensive, and also causes a waste of personnel.

[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] The working power of the warning device of the utility model comes from the vehicle and does not require a separate external power supply. The connection and disconnection of the warning device can be controlled by an internal switch, and the DC110V is converted into DC12V by the power conversion module to provide the required power for the warning device. The DC12V is sent to the signal module, and then transmitted to the infrared module through the signal module. The infrared module will detect that there are people working or passing by within a range of 5 meters around, and it will be sent to the signal conversion module. The signal conversion module sends a signal to the light alarm, which quickly flashes a red light alarm and is accompanied by an alarm (there is electricity in this part of the vehicle, please stay away from here). The alarm can be increased or decreased by the volume adjustment switch, and the voice reminder is continuous and periodic for 5 seconds, reminding the operating personnel or passers-by to be careful of electricity nearby, pay attention to safety, and beware of electric shock accidents.

[0023] Figure 1 It is a structural schematic diagram of a low-voltage power supply warning device for railway vehicles of the utility model. The EMU vehicle includes: an urban railway vehicle (referred to as vehicle) 100, a warning device 200 and a ground external power supply 300 connected in sequence. The ground external power supply 300 provides a DC110V power supply to the urban railway vehicle 100 through a first line 110, and the urban railway vehicle 100 provides power to the warning device 200 through a second line 210. At the same time, the warning device 200, within a range of 5 meters, when it detects that someone is approaching, the warning device 200 will issue a sound alarm and a light alarm, and the voice prompt method will continue for 5 seconds periodically: "There is electricity in this part of the vehicle, please stay away from here!", to warn people not to get close to prevent electric shock accidents.

[0024] Figure 2 yes Figure 1The internal diagram of the warning device 200. The warning device 200 mainly includes the following connected in sequence: switch, power conversion module, information collection module, infrared module, signal conversion module, volume adjustment, sound alarm; the signal conversion module is also connected to the light alarm. The DC110V power sent in by the second line 210 can control the connection and disconnection of the warning device 200 through the switch. After the switch, the DC110V power is converted into a DC12V power supply through the power conversion module and reaches the signal collection module; the signal is collected and transmitted to the infrared module; when someone is detected approaching within a range of 5 meters, it is transmitted to the sound alarm and light alarm through the signal conversion module, and a periodic voice prompt is given for 5 seconds: "There is electricity in this part of the vehicle, please stay away from here!", which serves to warn people around.

[0025] The working power of the warning device 200 comes from the urban railway vehicle 100, which is DC110V power supply, not through batteries or separate AC220V power supply, and does not require a separate external power supply, thus avoiding the situation where there is no power supply nearby, and also preventing the battery from running out of power or the warning from being interrupted. This method is more convenient and faster. The first line 110 provides power for the warning device 200, and the connection and disconnection of the warning device 200 can be controlled by an internal switch. After passing through the switch, the power conversion module converts DC110V into DC12V to provide the required power for the warning device 200, and the DC12V is sent to the signal acquisition module, and then transmitted to the infrared module through the signal acquisition module. When the infrared module detects that there are people working or passing by within a range of 5 meters, it will send it to the signal conversion module. The signal conversion module sends a signal to the light alarm, which quickly flashes a red light alarm, and at the same time, a sound alarm sounds: "There is electricity in this part of the vehicle, please stay away from here!" The sound alarm can be increased or decreased by the volume adjustment switch, and the sound alarm is continuous and periodic for 5 seconds, reminding the operating personnel or passers-by to be careful of electricity nearby, pay attention to safety, and beware of electric shock accidents.

[0026] The utility model discloses a low-voltage electricity warning device for railway vehicles, which avoids the risk of electric shock accidents by means of sound alarm, light alarm and voice prompt, and reminds passers-by and workers near the battery or the low-voltage box at the vehicle end in real time to work carefully and be alert to electric shock accidents.

[0027] The utility model discloses a low-voltage electricity warning device for railway vehicles, which saves manpower and money, is safer and more reliable, can effectively prevent people from getting electric shock, and improves work efficiency.

[0028] The utility model discloses a railway vehicle low-voltage electricity warning device, which is convenient and safe. When detecting someone approaching, it will automatically sound and light alarm and give voice prompts to remind passers-by. This is smarter and more convenient. As long as the vehicle is supplied with DC110V power, there will always be prompt information, and there is no need to provide an external power supply for the equipment separately. This is more convenient and reliable. There is also no power failure or power outage of the equipment.
