Embodiment 1

[0046] Such as figure 2 As shown, an unattended vigilance device provided by the present invention includes an unmanned vigilance effective action part K1 / K2 / K3, an audible and visual alarm device, a brake execution part and a control unit; the input ends of the control unit are respectively It is connected to the output terminals of K1 / K2 / K3 and DCU, which are unattended effective action parts, and the output terminals of the control unit are respectively connected to the sound and light alarm device and brake execution parts through hard wiring; The duration of the closing of parts K1 / K2 / K3, the duration of non-closing of all unattended effective action parts K1 / K2 / K3, and the zero-speed signal output by the DCU to control the action of the sound and light alarm device and the brake actuator.

[0047] Such as image 3 As shown, the control unit includes a first intermediate relay A, a second intermediate relay E, a first delay relay B, a second delay relay C and a third de...

Embodiment 2

[0068] Such as Figure 5 As shown, a kind of unmanned vigilance device provided by the present invention includes unmanned vigilance effective action parts, sound and light alarm device, brake execution part and LCU; , the output end of DCU, and the output end of LCU is respectively connected with the sound and light alarm device and the brake execution part through hard wiring; The non-closed duration and the zero-speed signal output by the DCU are used to control the action of the sound and light alarm device and the brake actuator. When the microcomputer network control system is cut off due to failure, the LCU realizes the unmanned vigilance function, which improves the safety of driving.

[0069] In this embodiment, the LCU can be a programmable controller, which realizes the control logic of the unmanned vigilance function through programming, and has the characteristics of flexible control mode, simple programming, intuitive wiring, and clear maintenance.

Abstract

The invention discloses an unmanned alert device and a realization method of an unmanned alert function under an emergency traction mode. An input end and an output end of a control unit are correspondingly connected with an unmanned alert effective action part, a sound and light alarm device and a brake executive part through hard wires. When a microcomputer network control system fails and is removed, the unmanned alert function is achieved through the control unit, the signal transmission is more reliable through the hard wires, the problem that the unmanned alert function cannot be achieved when the microcomputer network control system fails and is removed is solved, and the safety of traveling is greatly improved; and at the same time, whether the unmanned alert effective action partis continuously pressed or not pressed for a long time can be monitored, and the safety of traveling is further improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to an unmanned vigilance device and a method for realizing the unmanned vigilance function in an emergency traction mode. Background technique [0002] The rail locomotive is equipped with an unmanned alert device. When the locomotive driver operates the locomotive, the unmanned alert device can monitor the driver's mobility, prevent the driver from being inactive, and implement braking to stop the train when the situation occurs. Ensure driving safety. [0003] When the locomotive is at rest (that is, when the vehicle speed is zero), the unmanned vigilant device does not act. During the traction stage of the locomotive, the unmanned alert device is activated at intervals to remind the driver to pay attention to the operation. When the vehicle speed is not zero, the unmanned vigilance device enters the monitoring state. Within a period of time after entering the ...
