The embodiment of the invention discloses a train ventilation system, which is shown in figure 1 and comprises the following components:
an energy storage power supply air inlet 02 of a smoke stop valve 01 is arranged at the opening;
the environment sensor 04 is positioned between the smoke stop valve 01 and the energy storage power supply 03;
when the environment sensor 04 monitors that the environment is abnormal, a valve closing signal is sent to the smoke stop valve 01 to close the processor 05 of the smoke stop valve 01.
The environment sensor 04 may be a smoke temperature composite probe, or may be a temperature sensor and a smoke detector.
Specifically, because including 6 energy storage power air intake 02 on the train generally, consequently correspond 6 flue gas stop valves 01, these flue gas stop valves 01 generally adopt parallel connection, unified control.
Specifically, the signal transmission between the smoke stop valve 01 and the processor 05 and the signal transmission between the environment sensor 04 and the processor 05 may be wired communication or wireless communication.
The invention discloses a train ventilation system, comprising: the opening is provided with an energy storage power supply air inlet of a smoke stop valve; the environment sensor is positioned between the smoke stop valve and the energy storage power supply; and when the environment sensor monitors that the environment is abnormal, a valve closing signal is sent to the smoke stop valve so as to close the processor of the smoke stop valve. According to the train ventilation system, when the environment sensor detects that the environment is abnormal, the valve closing signal can be sent to close the smoke stop valve, so that smoke is prevented from escaping through the air inlet of the energy storage power supply, the situation that toxic smoke is generated by the energy storage power supply when the energy storage power supply fails to affect air in a passenger room is avoided, and safety of passengers in the passenger room is guaranteed.
Correspondingly, the embodiment of the invention discloses a method for monitoring energy storage power supply smoke, which is applied to any one of the train ventilation systems, and as shown in fig. 2, the method comprises the following steps:
s1: monitoring the environment of the energy storage power supply through an environment sensor in the train ventilation system;
specifically, step S1 includes:
and monitoring the ambient temperature and the smoke concentration of the energy storage power supply through the environmental sensor.
S2: when the environment of the energy storage power supply is abnormal, a valve closing signal is sent to a smoke stop valve in the train ventilation system through the environment sensor;
wherein, to the unusual judgement foundation of environment of energy storage power, mainly include ambient temperature and flue gas concentration, except that in addition, other signals of energy storage power also can regard as the judgement foundation. The judgment can be realized by a basic NAND gate circuit according to the idea of sending a valve closing signal.
Therefore, in step S2, the smoke shutoff valve may be specifically configured to send the valve closing signal to the smoke shutoff valve through the environment sensor when the environment temperature exceeds the environment temperature threshold and the smoke concentration exceeds the concentration threshold.
Referring to the logic control diagram shown in fig. 3, in step S2, when the energy storage power supply satisfies a valve closing condition, a valve closing signal is sent to the smoke shutoff valve through the environment sensor;
wherein, the valve closing condition is specifically as follows: the environment temperature exceeds an environment temperature threshold, the smoke concentration exceeds a concentration threshold, the temperature of the energy storage power supply exceeds a power supply temperature threshold or the communication fault of the energy storage power supply, and the contactor of the energy storage power supply is in a disconnection state.
It can be understood that the specific setting of the valve closing condition can more accurately and effectively close the smoke stop valve when the energy storage power supply has smoke faults, and the possibility of misjudgment of other interference conditions is reduced.
S3: and closing the smoke stop valve by using the valve closing signal.
Further, the energy storage power supply flue gas monitoring method may further include:
when the power supply of the smoke stop valve is normal, monitoring an action signal of the smoke stop valve and the state of the smoke stop valve;
when the smoke stop valve is not closed in a first time period after the valve closing signal is sent, judging that the smoke stop valve is in fault;
and when the valve opening signal keeps that the smoke stop valve is not opened in a second time period, judging that the smoke stop valve is in fault.
Specifically, the power supply of the smoke stop valve is generally DC24V, and both the first time period and the second time period can be set to 160s, and if an action signal is sent to the smoke stop valve, but the smoke stop valve does not perform corresponding actions within a specified time, it means that the smoke stop valve is faulty.
Specifically, the fault judgment logic diagram of fig. 4 can also be directly referred to, and whether the flue gas stop valve has a fault can be judged according to the fault judgment logic diagram. Wherein the valve closing signal is 0, namely the valve opening signal is kept, and the valve feedback of the smoke stop valve correspondingly indicates that the smoke stop valve is closed or opened.
It can be understood that, as an accident warning processing device, whether the smoke stop valve can act rapidly in an emergency is a very important consideration, so that whether the smoke stop valve fails is checked periodically according to the method, and the failed smoke stop valve is replaced, so that the smoke stop valve can be ensured to react rapidly when an accident occurs.
In addition, it should be noted that when the smoke stop valve is closed, the contactor of the energy storage power supply is not allowed to be attracted, and only when the smoke stop valve is opened and the energy storage power supply can dissipate heat, the contactor of the energy storage power supply can be attracted to enable the energy storage power supply to work. In fact, the probability of failure of the energy storage power supply is low, and the smoke stop valve is in an open state by default, so that the energy storage power supply can work conveniently.
In this embodiment, when environmental sensor detected the environment unusual, can send and close the valve signal and close the flue gas stop valve to prevent the flue gas and pass through energy storage power air intake and escape, avoided the energy storage power to produce poisonous flue gas when the trouble and influence the passenger room air, guaranteed passenger's in the passenger room safety.

the monitoring module 11 is used for monitoring the environment of the energy storage power supply through an environment sensor in the train ventilation system;
the signal sending module 12 is used for sending a valve closing signal to a smoke stop valve in the train ventilation system through the environment sensor when the environment of the energy storage power supply is abnormal;
and the valve closing module 13 is used for closing the smoke stop valve by using the valve closing signal.
In this embodiment, when environmental sensor detected the environment unusual, can send and close the valve signal and close the flue gas stop valve to prevent the flue gas and pass through energy storage power air intake and escape, avoided the energy storage power to produce poisonous flue gas when the trouble and influence the passenger room air, guaranteed passenger's in the passenger room safety.
