Example 1:
in order to better explain the advantages and benefits of the circuit of the present invention, a diagram of the vigilance control circuit is shown in fig. 1, taking a certain subway vehicle which is successfully operated for years in China as an example.
The warning circuit independently forms a logic loop only when the cab is activated, and the specific control logic and operation are as follows:
(1) after the vehicle is activated by a storage battery and an operation end, in a static state, because a zero-speed relay ZVR is electrified, a normally open contact of the zero-speed relay ZVR is closed, a coil of an alert relay DMAR is electrified, two normally closed contacts of the zero-speed relay DMAR are disconnected, the electrical delay action alert relays DMTDR1 and DMTDR2 are not electrified, and subsequent control logic is cut off. The state is equivalent to a bypass state that a driver triggers a vigilance function by operating a master handle DMC of a driver controller, so that the driver can release two hands before departure and prepare for the departure.
(2) The same bypass function can also play a role in bypassing the alert function in the case of an ATO scene, an ATB foldback scene, an operation of a DMBB bypass button, and the like.
In the case of non-signal system control (such as ATP), the driver must press the master controller DMC to maintain the alert control circuit during the running of the vehicle. Once a driver leaves the handle position, the relay DMAR loses power, the normally closed contact of the relay DMAR is closed, further the delay action alert relays DMTDR1 and DMTDR2 start to be powered on for timing, if the time exceeds 3 seconds (can be adjusted), an alert buzzer is sent out to remind the driver to operate the master handle DMC of the driver controller to maintain alert control, the buzzer disappears after the driver operates, and the vehicle runs normally; when the buzzer alarms for more than 2 seconds (adjustable), the DMTDR2 delays to disconnect the normally closed contact, so that the emergency braking safety loop is powered off, and the emergency braking is directly triggered (the vehicle considers that a driver does not have a vehicle control condition).
The circuit has the following problems: when the alert function cannot play a protection role due to the fact that a circuit of the alert circuit or some equipment in the circuit is broken down, the alert protection function fails at the moment, and emergency braking cannot be triggered.
