Description
Technical Field
The invention relates to the technical field of fuel cell safety control, in particular to a method for remotely controlling a hydrogen storage system of a hydrogen fuel locomotive to discharge hydrogen.
Background
Along with the popularization and application of hydrogen fuel cells in the bus and heavy truck industries, an intelligent vehicle-mounted hydrogen storage system also becomes normal equipment.
In recent years, rolling stock companies in the middle car group begin to research hydrogen fuel powered locomotives, and on-board hydrogen storage systems are necessary equipment. The current vehicle-mounted hydrogen storage system mostly adopts a type III high-pressure hydrogen cylinder with the pressure of 35Mpa, and a type IV hydrogen cylinder with the pressure of 70Mpa is gradually popularized in the future. For the use of the high-pressure hydrogen storage system on a locomotive, the safety is the first position, and the safety control strategy of the hydrogen storage system needs to be further optimized and enhanced according to the working condition characteristics of the locomotive.
The current vehicle-mounted hydrogen storage system needs to be discharged in a charged way under the normal condition, and the charged discharging condition is: firstly, a manual discharge valve or a discharge electromagnetic valve in a low-pressure discharge pipeline of the hydrogen storage system needs to be opened, and the condition II is that: the hydrogen storage system is controlled by electricity and needs to send out a valve opening instruction through the whole vehicle controller to open the solenoid valve of the bottle valve and the solenoid valve of the low-pressure pipeline. With the above conditions, the discharge passage can be opened. If the locomotive is unable to provide control power to the hydrogen storage system for emergency venting or remote monitoring of the hydrogen storage system safety status due to long-term parking or other extreme conditions. Under the condition that the hydrogen storage system is electrified, a controller, a concentration sensor, a pressure sensor, a bottle valve electromagnetic valve and a pressure reducing electromagnetic valve can acquire control electricity, the hydrogen storage system parked for a plurality of days can remotely monitor the health state of the hydrogen storage system through a ground expert system, whether hydrogen leakage exceeds standard, whether high and low pressure is normal, whether the residual hydrogen quantity is sufficient, and whether each bottle valve electromagnetic valve and pressure reducing valve electromagnetic valve work normally; more importantly, the hydrogen storage system is in a dangerous state through on-site inspection or remote monitoring, and the hydrogen emission is needed to reduce the safety risk.
The document CN 108091905B discloses an intelligent fuel cell hydrogen storage system, which comprises a hydrogen storage tank, a data acquisition unit, a data comparison unit, a control unit and an execution unit, wherein the execution unit is a safety valve, the safety valve is arranged on the hydrogen storage tank, the communication between the hydrogen storage tank and the outside is realized through the safety valve, the safety valve is provided with a high-frequency switch component, and the discharge of hydrogen in the hydrogen storage tank is controlled through the opening and closing of the high-frequency switch component; the intelligent fuel cell hydrogen storage system further comprises an anti-backfire device, and the anti-backfire device is arranged between the hydrogen storage tank and the safety valve. The safety valve for discharging hydrogen is installed on the hydrogen outlet of the hydrogen storage tank, the opening and closing frequency of the safety valve is controlled by an electromagnetic valve to achieve controllable discharge, and the opening and closing frequency of the safety valve is controlled by the pressure in the bottle and the concentration value of leaked hydrogen around the hydrogen storage tank to obtain different triggering conditions. The tempering preventing device is arranged between the hydrogen storage tank and the safety valve, so that the high-pressure hydrogen of the hydrogen storage tank is discharged from the safety valve, the hydrogen is not decompressed, the discharge pipeline of the safety valve is not led out to a far distance, and the high-pressure hydrogen directly discharged through the safety valve is tempered easily at a discharge port (if flame exists at the discharge port) because the discharge pipeline is short, so that the hydrogen storage tank is exploded. The length of the discharge pipeline is actually increased, so that an anti-backfire device is not needed, and because the high-pressure hydrogen is discharged, the discharge pipeline is longer, backfire cannot be generated, the high-pressure hydrogen is impacted by high pressure to be discharged out of the discharge port, and if the discharge port has flame, only the discharge port has flame, so that backfire cannot be generated. The high-pressure discharge is dangerous, the bottle valve and the tail valve on the hydrogen storage tank are provided with temperature-driven safety pressure relief devices TPRD (thermal-Activated Pressure Relief Device), and the high-pressure discharge is carried out by fusing a hot melt piece on a discharge gas path in the bottle valve or the tail valve under the condition of ultra-high temperature, so that the high-pressure discharge is realized, and the connected discharge pipeline is led to a top discharge port of a locomotive or a passenger car. The hydrogen storage system in the non-extreme case can not adopt the high-pressure discharge mode, and the normal and safe discharge mode is to discharge the hydrogen at low pressure after decompression. The hydrogen storage system has no electricity, and the safety valve of the hydrogen storage tank can not be opened for discharging.
The composition of the hydrogen supply system of the passenger car disclosed in the document 'study on hydrogen supply system of hydrogen fuel cell passenger car, lin Jiaxiang, passenger car technology and study, and 4 th 1-3 of 2021' is shown in fig. 1, and represents the pipeline principle of the main stream product of the current hydrogen supply system. The main function of the hydrogen supply system is to supply the high-pressure hydrogen in the high-pressure gas cylinder to the fuel cell through the main electromagnetic valve after the high-pressure hydrogen is depressurized through the pressure regulator, namely the depressurization valve. The bottle valve is controlled by the hydrogen supply system controller, the hydrogen supply system controller can receive data collected by the high-pressure sensor, the temperature sensor, the low-pressure sensor and the concentration sensor in the hydrogen supply system, and the collected data are used for intelligently controlling the bottle valve electromagnetic valve and the main electromagnetic valve, namely the low-pressure electromagnetic valve, so that the hydrogen is safely supplied to the fuel cell system. The hydrogen supply system controller is in network communication with the vehicle-mounted microcomputer, and the vehicle-mounted microcomputer can control the start and stop of the hydrogen storage system preferentially. The blow-down valve in the low pressure drain line is a manual drain valve. After the hydrogen supply system is loaded, the system pipeline nitrogen pressure maintaining and hydrogen gas tightness test and the whole system hydrogen replacement are required to be carried out, and an air release valve is required to be operated to release the system pipeline or the whole system gas. Therefore, the manual hydrogen discharge is a conventional operation, when the hydrogen supply system discharges hydrogen, the solenoid valve of the bottle valve and the main solenoid valve in the low-pressure pipeline need to be electrically opened, and if the on-vehicle power supply cannot be obtained by the hydrogen supply system controller, the hydrogen discharge cannot be operated. The hydrogen supply system has no design of an automatic discharge electromagnetic valve and a 24V standby rechargeable battery, and has no function of controlling discharge by a remote control module. The hydrogen supply system can not wake up the locomotive hydrogen storage system remotely during the power-off parking period of the vehicle, so that the remote monitoring and the safe and controllable emission of the hydrogen storage system can not be realized, the use safety risk can be increased, and the working efficiency is low.
The current vehicle-mounted hydrogen storage system mostly adopts a type III high-pressure hydrogen cylinder with the pressure of 35Mpa, and a type IV hydrogen cylinder with the pressure of 70Mpa is gradually popularized in the future. In the hydrogen storage system of high-pressure gas, once the vehicle collides and burns, leakage and combustion explosion of the hydrogen storage system can be caused, and unnecessary casualties and property loss are generated. Therefore, the hydrogen storage system needs to be monitored in the operation process and the parking process of the locomotive, and even the hydrogen is discharged according to the needs under the very condition, and the remote monitoring is an effective method for saving the cost of manpower and material resources.
Based on this, there is room for improvement in controlling intelligent discharge of hydrogen gas in the case of power-off parking of the hydrogen storage system.

As shown in fig. 3, the method for remotely controlling the hydrogen storage system of the hydrogen-fueled locomotive to discharge hydrogen according to the present invention comprises the steps of:
step 1, in the process that a locomotive microcomputer system is not put into operation or the locomotive is in power-off parking, a remote control module 4 wakes up a hydrogen storage system, and electric components of the hydrogen storage system obtain control electricity of a power supply module 5, namely a controller 3, a high-pressure sensor 8, a low-pressure sensor 11, a first concentration sensor 9, a second concentration sensor 12, a cylinder valve electromagnetic valve 62, a cylinder valve temperature sensor 63, a cylinder valve electromagnetic valve 10 and a discharge electromagnetic valve 14 obtain control electricity of the power supply module 5;
step 2, if the controller 3 has no fault after self-checking, the remote control module 4 sends out valve opening instructions of the bottle valve electromagnetic valve 62 and the low-pressure electromagnetic valve 10, and the valve opening instructions are put into operation; or after the safety monitoring of the hydrogen storage system is finished, the remote control module 4 sends out a valve closing instruction of the bottle valve electromagnetic valve 62 and the low-pressure electromagnetic valve 10 and the power supply module 5 controls electricity; if the controller 3 has a first-level fault after self-inspection, but the conditions still allow the bottle valve electromagnetic valve 62 and the low-pressure electromagnetic valve 10 to open, the remote control module 4 sends out a valve opening instruction and a discharging instruction to perform controllable intelligent hydrogen discharging. When a primary failure occurs, for example, a circuit failure of a single cylinder valve solenoid valve 62, the controller 3 closes the corresponding cylinder valve solenoid valve 62; the first concentration sensor 9 and/or the second concentration sensor 12 detects a slight leakage of hydrogen gas; the cylinder valve temperature sensor 63 detects a slight exceeding of the temperature; the low pressure sensor 11 detects a slight pressure overrun; the controller 3 does not process and still allows opening of the non-malfunctioning cylinder valve solenoid 62 and the low pressure solenoid 10.
In some embodiments, in step 1, the remote control module 4 wakes up the hydrogen storage system by enabling the control hydrogen storage system mode.
In some embodiments, in step 2, the controller 3 determines whether the hydrogen storage system has a fault or a fault level according to the data transmitted by the cylinder valve temperature sensor 63, the high pressure sensor 8, the low pressure sensor 11, the first concentration sensor 9, and the second concentration sensor 12, and the fault signals, the short circuit signals and the open circuit signals of the cylinder valve solenoid valve 62, and the comparison between the fault signals of the communication between the controller 3 and the locomotive microcomputer system and the ground control system and the set values of the controller 3.
As shown in fig. 2 to 4, the method for remotely controlling the hydrogen storage system of the hydrogen-fueled locomotive to discharge hydrogen according to the present invention is as follows: when the control power of the locomotive 110V power supply can be obtained, the 24V battery 52 is charged under the condition of not being full of power, and when the remote control module 4 wakes up the hydrogen storage system, the power supply module 5 preferably uses the 110V to 24V power supply 51. When the locomotive 110V power supply control power cannot be obtained, the 24V battery 52 plays a redundant backup, the remote control module 4 obtains control power for other electric components (the controller 3, the bottle valve temperature sensor 63, the high-pressure sensor 8, the low-pressure sensor 11, the first concentration sensor 9 and the second concentration sensor 12) of the hydrogen storage system except the remote control module 4 through the power supply of the control coil of the first control contactor K1 (the suction of the K1 contactor), and at the moment, the hydrogen storage system is remotely monitored to obtain the health state of the hydrogen storage system.
The remote control module 4 controls the bottle valve electromagnetic valve 62 and the low-pressure electromagnetic valve 10 to be electrically opened through the hydrogen storage system controller HMS, and the remote control module 4 controls the discharge electromagnetic valve 14 to be electrically opened through the control coil of the second control contactor K2 (the suction of the K2 contactor), so that the intelligent discharge and stop of hydrogen can be performed. The intelligent discharging is realized by collecting data provided by the bottle valve temperature sensor 63, the high pressure sensor 8, the low pressure sensor 11, the first concentration sensor 9 and the second concentration sensor 12 respectively, and the bottle valve electromagnetic valve 62 and the low pressure electromagnetic valve 10 are opened or closed by the hydrogen storage system controller HMS through condition comparison, so that the hydrogen discharging and stopping discharging of the hydrogen storage system are carried out. If the hydrogen concentration leakage is moderately out of standard, the hydrogen storage system controller HMS can send out a valve closing instruction (the bottle valve electromagnetic valve 62 and the low-pressure electromagnetic valve 10 are closed) and trigger the discharge electromagnetic valve 14 to be closed in a power-off mode (the K1 contactor is opened), and the discharge is automatically stopped. For safety, the discharge is again performed, and the discharge solenoid valve 14 is controlled electrically again.
According to the method for discharging hydrogen by the hydrogen storage system of the remote control hydrogen fuel locomotive, the hydrogen in the hydrogen storage bottle 65 and the pipeline is controllably discharged through the low-pressure discharge pipeline before the preset risk comes, so that the safety risk is reduced; when the locomotive is powered off, the hydrogen storage system needs to be powered on, and the power module 5 is started at the moment, so that the health state of the hydrogen storage system can be detected or remotely monitored, the hydrogen storage system can be subjected to air tightness, replacement, emission and other works, and the working efficiency is improved. The power supply module 5 serves as a stand-by power supply for the remote control module 4, which reduces the cost of the remote control module 4 for separately setting the power supply. The power module 4 is started in real time, so that the power consumption of the power module 4 is saved; the method can be used for regularly monitoring the hydrogen storage system to obtain the safety data of the hydrogen storage system, and can be used for carrying out health diagnosis and taking safety measures on the hydrogen storage system, so that the labor cost is reduced and the safety is prevented; the remote control hydrogen storage system emission method is not only suitable for locomotive industry, but also applicable to other industries, and has remarkable economic benefit; the remote control hydrogen storage system discharging method can also be used for on-site discharging, the manual discharging valve 13 is still reserved, an operator can conveniently select various operation modes to perform on-site work, and the method is flexible and convenient.
The foregoing examples merely illustrate embodiments of the invention and are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
