Description

Technical Field

[0001] The invention relates to the technical field of railway electric inspection vehicle operation status monitoring devices, and in particular to a railway electric inspection vehicle and a vehicle ladder operation status monitoring and alarm device. Background Art

[0002] With the development of science and technology and the increase in the demand for on-site operations, the use of railway electric inspection vehicles and ladders has become increasingly frequent, and relevant regulations and systems have become increasingly mature and stable. However, due to the lack of monitoring and alarm devices for the operation status of railway electric inspection vehicles and ladders, it is difficult for us to implement safety control measures in accordance with regulations and systems. For example, the regulations clearly state that the speed limits of 5km / h, 10km / h, and 20km / h must not be exceeded according to the on-site conditions, and anti-dumping measures must be taken when the outer rail is overheight greater than 100mm. The on-site inspection vehicles and ladders cannot grasp the surrounding on-site conditions and real-time operation status in real time when they are in operation. In order to implement the above control requirements, there are situations where regulations and systems are difficult to implement. Summary of the invention

[0003] In order to solve the above technical problems, the present application provides a railway electric inspection vehicle, a vehicle ladder operation status monitoring and alarm device, and the present invention is implemented through the following technical solutions: A railway electric inspection vehicle and ladder operation status monitoring and alarm device comprises a physical part, an operation signal acquisition system, a program integrated execution platform, an audible and visual alarm system, an operation status display system, and a power supply system.

[0004] The physical part includes an electric inspection vehicle and a car ladder. The operation signal acquisition system includes a speed sensor, an outer rail superheight sensor, and a slope sensor. The electric inspection vehicle and the car ladder are each equipped with a speed sensor, an outer rail superheight sensor, and a slope sensor. The program integrated execution platform includes an STC processor. The signal output ends of the speed sensor, the outer rail superheight sensor, and the slope sensor are electrically connected to the signal input end of the STC processor. The sound and light alarm system includes an LED module, an active buzzer module, and a voice playback module. The signal output end of the STC processor is electrically connected to the LED module, the active buzzer module, and the voice playback module.

[0005] The operation signal acquisition system is placed in a signal acquisition box, and the speed sensor, outer rail superheight sensor, and slope sensor are all fixedly connected in the signal acquisition box. There are two signal acquisition boxes, one of which is fixedly connected to the electric inspection vehicle, and the other signal acquisition box is fixedly installed on the vehicle ladder.

[0006] The electric inspection vehicle and the vehicle ladder are respectively equipped with a sound and light alarm system.

[0007] The signals collected by the speed sensor, outer rail superelevation sensor and slope sensor are uploaded to the STC processor via a wireless signal transmission system.

[0008] As a preferred solution, the power supply system is a 5V rechargeable lithium battery pack, and the power supply system is electrically connected to the operation signal acquisition system and the sound and light alarm system.

[0009] As a preferred solution, the operating status display system is an LED liquid crystal display module, and the LED liquid crystal display module is electrically connected to the STC processor.

[0010] As a preferred solution, a balancing bead is installed at the bottom of the signal acquisition box.

[0011] Compared with the prior art, the invention has the following beneficial effects: the invention fills the gap in the current railway electric inspection trolley and ladder status monitoring technology, has low overall cost, and can meet long-term use. The program integrated execution platform STC processor receives the monitoring signal of the physical part of the monitoring, sends a signal to the LED LCD display module of the operation status display system to display the real-time status, and sends a signal to the sound and light alarm system when the STC processor analyzes the monitoring signal and exceeds the set status threshold.

[0012] The LED LCD display module of the operating status display system sends feedback signals from the STC processor and displays the operating speed value, outer rail superelevation value, and slope value in the selected mode in real time.

[0013] This device fundamentally solves the problem that the operating status of electric inspection vehicles and car ladders cannot be monitored. It can truly reflect the requirements of the operating speed of electric inspection vehicles and car ladders, the need to prevent tipping due to overheight of the outer rail, and the need for braking control on large slopes, thereby ensuring safe and controllable on-site operations as a whole.
