Description
Technical Field
The invention belongs to the technical field of ventilation control of rail transit vehicles, and relates to a many-to-many emergency ventilation control method, a system and a vehicle.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
In the operation process of the rail transit vehicle, if the vehicle has no high voltage due to faults of lines, vehicle parts and the like, the vehicle air conditioner enters an emergency ventilation working condition, and the vehicle storage battery provides three-phase alternating current for the air conditioning system through the emergency ventilation inverter.
At present, an emergency ventilation inverter is arranged in each carriage, the inverter is hung on a direct current bus of a vehicle, and is powered by a storage battery through the direct current bus under an emergency working condition and then is inverted into three-phase alternating current to power an air conditioner of the carriage. If the air conditioning system detects three-phase voltage abnormality or receives an emergency ventilation instruction, the emergency ventilation inverter of the vehicle is directly driven through the hard wire interface, so that the emergency ventilation inverter is in one-to-one correspondence with the air conditioner, and all carriages are mutually independent without considering the entering and exiting control logic problems of the tight working condition.
However, along with continuous propulsion of the system fusion of the rail transit vehicle, the auxiliary inverter integrating the tightening function starts to be applied, as shown in fig. 1, the contactor K20 is closed under the tightening working condition, the electricity of the storage battery flows back to the front-stage direct-current bus of the charger through the contactor K20, at the moment, the rectifying module works in a reverse inversion mode, the direct-current voltage is changed into alternating-current voltage, the alternating-current voltage is transmitted through the transformer to establish the direct-current voltage for the inverter bus, and at the moment, the inverter starts to work to output alternating-current voltage to supply power for the air conditioner ventilator.
The integrated design eliminates an independent emergency ventilation inverter, saves space under the vehicle, reduces the weight of the vehicle and saves the configuration cost. But with the control logic for emergency ventilation conditions. According to the different vehicle marshalling, the auxiliary system can adopt extended power supply or grid-connected power supply, but no matter what power supply mode is adopted, the number and the positions of the auxiliary inverters are in one-to-one correspondence with the air conditioner, so that the air conditioner cannot be directly driven by the air conditioner system to supply power to the ventilator, but the auxiliary inverter working in a tight-through working condition supplies power to the air conditioner through a through alternating current bus, and therefore, the starting and stopping of the emergency ventilation working condition are not the control of a single vehicle, but the control of the whole vehicle. Particularly, for vehicles with more groups, such as 8-group vehicles, grid-connected power supply is generally adopted, the number of auxiliary inverters is large, the emergency ventilation mode control needs to ensure that an emergency ventilation request of an air conditioner can be received (considering the fault condition of an air conditioner controller), whether the inverter has a condition of entering a tight-pass working condition (considering whether the auxiliary inverters are normal or not), and the like, and redundancy and reliability in the instruction transmission process also need to be fully considered.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

Example 1
As described in the background art, the conventional manner of directly interfacing with the emergency ventilation inverter by the air conditioner and one-to-one driving the emergency ventilation inverter of the vehicle to work for supplying power to the ventilator of the air conditioner of the vehicle is no longer applicable, and the embodiment provides a new many-to-many tight-through mode control method to solve the problem of controlling the emergency ventilation mode of the vehicle in which the emergency ventilation inverter and the air conditioner do not correspond one-to-one, and the control method provided by the embodiment considers the usability and reliability of the system.
In the following, 8 (N) vehicles are grouped, and a configuration of a complete vehicle configuration 5 (M) auxiliary power units (each auxiliary power unit can provide an emergency ventilation capacity of 12 kVA) is described by taking a grid-connected power supply mode as an example.
It should be noted that in other embodiments, the methods and systems provided by the present invention are not limited to the application objects described above. For vehicles with different marshalling and auxiliary reverse numbers, the control method is consistent, the number of judgment conditions is different according to different capacity calculation results, and only the adaptation is carried out.
Based on the configuration, through calculating 3 (namely K, the embodiment is 3, and only an example is adopted), the auxiliary working is reversed, and the power consumption requirement of the ventilator of the air conditioner in the whole row under the emergency ventilation working condition can be met.
Of course, in other embodiments, the specific values described above may be modified or adjusted according to specific circumstances and requirements.
The emergency ventilation mode control includes a control flow for entering a tight-pass condition, as shown in fig. 2, specifically including:
(1) entry conditions
A. The air conditioning system applies for entering an emergency ventilation mode, and 8 vehicles have any vehicle air conditioner to send an emergency ventilation request and then apply for the auxiliary system for entering the emergency ventilation mode; the condition that the air conditioning system applies for entering the emergency ventilation mode is that the three-phase voltage detection is abnormal or the network gives an instruction of entering the emergency ventilation working condition.
B. After the output voltage of the auxiliary inverter reaches the output voltage capable of meeting the emergency ventilation quantity, sending a tight-pass mode permission signal, wherein 3 auxiliary inverters send the tight-pass mode permission signal, and the permission signal can be judged to be valid;
C. the air conditioning system receives the "tight mode enable" signal and initiates emergency ventilation.
(2) Logic description
A. Auxiliary system
The "tight mode request" command is not responded to when the auxiliary system is in the normal operation mode. The auxiliary system enters a normal mode when there is a high voltage fault.
When the emergency ventilation mode request signal (hard wire or network) is received at a high level, the emergency ventilation mode request signal is considered to be received, but when the hard wire and network signals are inconsistent, a fault is reported.
And (3) judging entry conditions:
a. the auxiliary inverter itself has no fault;
b. the outside has no high pressure;
c. the battery voltage is higher than 87V (only in this embodiment, in other embodiments, the battery voltage can be adjusted according to specific conditions, and the minimum voltage value meeting the tight-pass requirement is generally required to be reversibly changed by auxiliary inversion);
when the above conditions are satisfied, the auxiliary reverse enters a tight-pass mode.
The auxiliary inverter outputs a voltage of 3AC330V (±3%) (in this embodiment, only the output voltage may be adjusted according to the specific situation) after entering the fast-pass mode, and a delay of 5s (in this embodiment, only the output voltage may be adjusted according to the specific situation) after outputting the output voltage, and the auxiliary inverter sends a signal of "fast-pass mode permission".
B. Air conditioning system
The air conditioning system confirms three conditions for entering the emergency ventilation mode: tight mode request (level); tight mode enable (level); detecting abnormality of the three-phase voltage; the specific implementation logic is shown in the following table:
in this embodiment, the detection range set by the three-phase power supply detector is 380v±10%, and the three-phase power supply detection always reports power supply abnormality during the auxiliary reverse output 330V voltage in the emergency ventilation state.
(3) Description of air conditioner implementation scheme
A. The air conditioning unit is in a non-standby state, and the controller receives an 'input power supply abnormality' signal fed back by the three-phase power supply detector; at this time, the corresponding air conditioning unit is stopped, the controller sends an 'enter emergency ventilation request (hard line)' to the auxiliary inverter, meanwhile, the air conditioning system also sends an 'enter emergency ventilation request (network)' to the auxiliary inverter through the network system, and after 15s of delay (only in the embodiment, the adjustment can be carried out according to the specific conditions in other embodiments), if the controller detects an 'emergency ventilation mode permission signal (hard line)' fed back by the auxiliary inverter, or receives an 'emergency ventilation mode permission' instruction issued by the network, the controller enters an emergency ventilation mode; if the emergency ventilation mode permission signal (hard line) is not received after 15s (only in the embodiment, the emergency ventilation mode permission signal can be adjusted according to the specific conditions in other embodiments) or the emergency ventilation mode permission command issued by the network is not received, the controller operates according to the normal working condition, and the controller locally reports the abnormality of the three-phase power supply detection relay.
B. The controller receives an instruction of entering an emergency ventilation working condition issued by a network, at the moment, the corresponding air conditioning unit is firstly stopped, then the controller sends a signal of entering an emergency ventilation request through a hard wire and the network, and the subsequent logic is the same as A; .
C. If the air conditioning unit is in a non-standby state, the controller receives an "emergency ventilation start permission signal (hard wire/network)", and at this time, the controller stops the air conditioning unit correspondingly, delays for 15 seconds (only in this embodiment, the air conditioning unit can be adjusted according to specific conditions), and then detects the "emergency ventilation start permission signal (hard wire/network)", if the signal still exists, the air conditioning unit enters an emergency ventilation mode, otherwise, the air conditioning unit operates according to normal working conditions.
(4) Vehicle implementation scheme
The "tight-pass mode request" signal is outputted by the air conditioner controller, and after the "or" logic is made through the hard wire and the protocol (namely, when any one of the air conditioners of the 8-group vehicles outputs the "request" signal), the request signal is sent to the auxiliary inverters of the 5 vehicles respectively, after the auxiliary inverters receive the "tight-pass mode request" signal, whether the condition is met or not is judged, and meanwhile, the "tight-pass mode permission" signal is outputted through the hard wire and the protocol, when the "tight-pass mode permission" signal sent by any not less than 3 auxiliary inverters is met, the "tight-pass mode permission" signal (in the embodiment, the "tight-pass mode permission" signal (sent through the hard wire or protocol) is sent to each vehicle air conditioner), and after the air conditioner system receives the "tight-pass mode permission" signal (hard wire or protocol), the tight-pass mode is entered.
In some embodiments, as shown in fig. 3, a process of exiting emergency ventilation is also included.
For auxiliary inverters
A. When the auxiliary inverter is in the tight-pass mode, after receiving a 'tight-pass mode exit' instruction (a 'tight-pass mode request' low level), the auxiliary inverter exits from the tight-pass mode and the system stands by.
B. When the auxiliary inverter is in the tight-pass mode, the high-voltage signal is monitored, the auxiliary inverter automatically exits the tight-pass mode, and enters the normal mode to operate after a delay of 5s (only in this embodiment, the auxiliary inverter can be adjusted according to specific conditions).
For air conditioning systems
In the emergency ventilation mode of the air conditioning system, when the controller cannot detect the "emergency ventilation start permission signal", after a delay of 15s (only in this embodiment, the adjustment can be performed according to the specific situation in other embodiments), whether the three-phase detection relay is normal is detected:
A. if the air conditioning system is normal, the air conditioning system enters a normal working condition to operate;
B. if the emergency is abnormal, the emergency ventilation mode is entered after the detection is continued for 15s in the standby state (only in this embodiment, the detection can be adjusted according to the specific situation in other embodiments), and a fault is reported that the emergency ventilation mode request is inconsistent with the permission signal feedback.
In the concrete implementation, if the vehicle has no LCU system, the vehicle can be realized by arranging a relay or a contactor and adding a train line, and the logic of '8 to 1' and '5 to 3' are respectively realized by connecting electric control devices in series and parallel;
if the vehicle is provided with the LCU system, the LCU can be used for respectively collecting output signals of an air conditioner controller and an auxiliary inverter (if any) of the vehicle, and after the LCU carries out logic operation, the LCU outputs an instruction for judging the air conditioner controller through a vehicle hard wire, so that the use of relays and train lines can be greatly reduced, and the circuit design is simplified.
The two are hard-wired implementations, and the network implementation is realized by the vehicle TCMS system for the logic control.

Example III
