Description
Technical Field
The invention relates to the field of rail transit, in particular to a reconnection train and a broken hook protection method and circuit thereof.
Background
At present, the physical connection mode of the reconnection train mainly comprises network communication reconnection, hard line reconnection, pipeline reconnection and coupler reconnection.
When the locomotive breaks the hook failure, the train can be separated. Network reconnection, hard line reconnection and pipeline reconnection are interrupted. If the coupler between the locomotive groups is broken, the network reconnection cables, the brake hoses and the hard line reconnection cables between the locomotives are broken. At this point all locomotives within the consist must automatically apply emergency braking to ensure driving safety. If a coupler between locomotive groups breaks or a brake hose between locomotives breaks, the train pipe pressure will automatically drop. If the locomotive does not send an emergency braking command, the locomotive braking system and the TCMS detect that the pressure P of the train pipe is reduced below a certain preset threshold value (P <2.9bar), and the TCMS unit judges that the locomotive has a broken hook fault or a brake pipe fault and needs to apply emergency braking to the locomotive to ensure the safety of the train. At present, when a train breaks a hook, a transmission path for applying emergency braking due to the broken hook comprises the following steps: train pipe reconnection, network reconnection cables, and hard wire reconnection cables (high effective hard wire reconnection or low effective hard wire reconnection). The master locomotive emergency brake command is transmitted by the transmission path to the slave locomotives to ensure that the train can reliably apply the emergency brake.
Pipeline reconnection: the master control locomotive and the slave control locomotive are coupled through a brake hose between the locomotives. When the master control locomotive applies emergency braking, the train pipe is decompressed, and the slave control locomotive braking unit automatically carries out emergency braking according to the decompression of the train pipe. If the angle cock of the locomotive train pipe is closed or the train pipe is blocked by foreign matters, the slave control machine train pipe can not reduce the pressure. The emergency braking instruction can not be transmitted to the slave control machine car through the train pipe, and meanwhile, because the network reconnection cable and the hard wire reconnection cable are interrupted, the emergency braking signal of the master control machine car can not be transmitted to the slave control machine car through the network and the hard wire. The slave control machine and the train can not apply emergency braking, and safety risks exist.
Network reconnection of cables: the master locomotive TCMS communicates through communication cables such as WTB/Ethernet and the like. When the master control locomotive applies emergency braking, the master control locomotive TCMS sends an emergency braking signal to the slave control locomotive through network communication, and the slave control locomotive braking unit controls the application of the emergency braking. When a network reconnection cable between the locomotives is broken or a gateway fails, the slave control locomotive cannot reliably receive a hook breakage protection instruction of the master control locomotive through a network, and safety risks exist.
High effective hardwire reconnection (as shown in fig. 1): the master control locomotive and the slave control locomotive are reconnected through hard wires. And the hook breakage protection command is transmitted to the slave control locomotive through high level, and the master control locomotive and the slave control locomotive apply emergency braking at the same time. The master control locomotive and the slave control locomotive are interrupted through a reconnection hard wire, the master control locomotive actually applies emergency braking to realize broken hook protection, the slave control locomotive cannot acquire a high-effective broken hook protection instruction and cannot realize broken hook protection, and safety risks exist.
Low effective hardwire reconnection (as shown in fig. 2): each locomotive is provided with two reconnection switches, and each switch is provided with three positions of a head, an outer and a tail. The single locomotive is used, one switch is set as a head, and the other switch is set as a tail. When the locomotive is in reconnection, the head reconnection switch of the locomotive group is set as 'head', the tail reconnection switch of the locomotive group is set as 'tail', and other change-over switches are set as external. As shown in the figure: the power supply of the locomotive emergency brake forms an emergency brake loop by ' locomotive 1-S01 ' → ' locomotive 1-S02 ' → W01 → locomotive 2-S01 ' → ' locomotive 2-S02 ' → W02. If the locomotive hook breaking W02 loses power, the locomotive realizes emergency braking. When the locomotives are reconnected, the reconnection conversion switch of each locomotive must be correctly set. If the setting is wrong, if the S01 reconnection switch for the lead locomotive of the consist is set to "head" and the S01 reconnection switch for the lead locomotive is set to "tail", the other locomotives cannot apply emergency braking. When the locomotive group breaks the hook, the head locomotive can implement the hook breaking protection, and other locomotives can not implement the hook breaking protection, so that the safety risk exists.

Detailed Description
The invention optimizes the hook breakage detection and protection circuit of locomotive reconnection and realizes reliable protection under the condition of hook breakage of the locomotive. Particularly, in the case of train pipe failure (closing or blocking) and network reconnection failure, a hook-breaking protection signal is reliably transmitted to the whole train set (comprising a master control locomotive and a slave control locomotive), so that the whole train can be controlled to apply emergency braking when the train detects the hook breaking.
As shown in fig. 3, in the embodiment of the present invention, the locomotive hook breakage protection hard wire control circuit includes the following three hard wires: DC110V negative line (i.e., power negative line, corresponding to line 0V in fig. 3), train emergency power line, train hook breakage detection line. The power supply of the train hook breakage detection line DC110V is provided by a master locomotive control battery (i.e. a control power supply). After the locomotive network marshalling is reconnected, the driver confirms the locomotive marshalling on the master control display of the master control locomotive. The TCMS (network control system) controls the local 'single machine/tail locomotive relay (see tail locomotive relay in figure 3) to be closed or opened' according to the state of the locomotive, and the automatic configuration of the hook breakage detection circuit is completed.
The DC110V control power supply of the master locomotive supplies power to the emergency brake power line through an occupation key (master control key), and the DC110V control power supply of the slave locomotive is isolated from the emergency brake power line through the occupation key (slave control key).
Under the mode of multi-locomotive reconnection, a master control locomotive 'single machine/tail locomotive relay' and a middle locomotive 'single machine/tail locomotive relay' are disconnected, the tail locomotive 'single machine/tail locomotive relay' is closed, and a DC110V power supply of a master control storage battery supplies the master control locomotive control power supply to a train disconnection detection line through an electric key (master key) → master control locomotive train emergency power line → reconnection cable train emergency power line → slave control train emergency relay contact → tail locomotive 'single machine/reconnection mode relay' contact.
