Example 1
Referring to a schematic structural view of a waste discharge apparatus control system shown in fig. 1, the present embodiment proposes a waste discharge apparatus control system for a railway vehicle, including: an air conditioning controller 100, an emergency ventilation inverter 102, a waste discharge device 104, a battery (not shown), and a temperature sensor (not shown).
The emergency ventilation inverter 102 is connected to the air conditioner controller 100, the waste heat discharging device 104, and the battery, respectively.
Specifically, the emergency vent inverter 102 has an A1 pin, an A2 pin, a B1 pin, a B2 pin, a B3 pin, an AC380V-U pin, an AC380V-V pin, and an AC380V-W pin.
The emergency ventilation inverter 102 is connected to the air conditioner controller 100 through a B1 pin, a B2 pin, and a B3 pin, wherein:
the pin B1 is configured to receive a first inverter start signal sent by the air conditioner controller 100.
The first inverter start signal may be a low level signal or a high level signal.
And the B2 pin is used for feeding back the working state of the emergency ventilation inverter to the air conditioner controller when the emergency ventilation inverter supplies power to the waste discharge device.
The pin B3 is configured to receive a second inverter start signal sent by the air conditioner controller 100.
The second inverter start signal may be a low level signal or a high level signal.
Therefore, the air conditioner controller of the waste discharge device control system in this embodiment, which combines the first inverter start signal and the second inverter start signal, sends a voltage control command to the emergency ventilation inverter.
Therefore, the air conditioner controller 100 can have the following four cases by the voltage control command transmitted to the emergency ventilation inverter:
1. the first inverter starting signal and the second inverter starting signal are both high-level signals;
2. the first inverter starting signal and the second inverter starting signal are both low level signals;
3. the first inverter starting signal is a high level signal, and the second inverter starting signal is a low level signal;
4. the first inverter starting signal is a low level signal, and the second inverter starting signal is a high level signal.
Therefore, the emergency ventilation inverter may provide different voltages to the waste device 104 according to different levels of the received first inverter start signal and the second inverter start signal, so that the waste device 104 ventilates the vehicle compartment according to different ventilation amounts.
The emergency ventilation inverter 102 is connected to the air conditioner controller 100 through an a1 pin and an a2 pin. Wherein, the A1 pin is connected with the positive pole of the storage battery; the A2 pin is connected with the negative pole of the storage battery.
The emergency ventilation inverter 102 is also connected to the waste device through an AC380V-U pin, an AC380V-V pin, and an AC380V-W pin.
The air conditioner controller is connected with the temperature sensor; the temperature sensor is installed on a carriage shell of the railway vehicle.
The temperature sensor is used for collecting temperature information outside a carriage of the railway vehicle and sending the collected temperature information to the air conditioner controller.
And the air conditioner controller is used for receiving the temperature information outside the carriage collected by the temperature sensor when the high-voltage equipment of the railway vehicle breaks down, determining the ventilation quantity of the waste discharge device according to the temperature information, generating a voltage control instruction of the emergency ventilation inverter according to the determined ventilation quantity, and sending the voltage control instruction to the emergency ventilation inverter.
The air conditioner controller can be connected with a vehicle-mounted controller of a railway vehicle, when a high-voltage equipment fault signal sent by the vehicle-mounted controller is received, the high-voltage equipment of the railway vehicle is determined to have a fault, a voltage control instruction of the emergency ventilation inverter is generated according to the received temperature information outside the carriage, collected by the temperature sensor, at the moment, the generated voltage control instruction is sent to the emergency ventilation inverter, and the emergency ventilation inverter is used for controlling the waste discharge device to perform emergency ventilation operation in the carriage.
And the emergency ventilation inverter is used for receiving a voltage control command sent by the air conditioner controller and outputting the voltage indicated by the voltage control command to the waste discharge device.
The waste discharge device is used for performing ventilation operation in a compartment of the railway vehicle under the control of the output voltage of the emergency ventilation inverter.
Specifically, in order to control an emergency ventilation inverter, the air conditioner controller determining a ventilation amount of the waste discharge device according to the temperature information, generating a voltage control command of the emergency ventilation inverter according to the determined ventilation amount, and transmitting the voltage control command to the emergency ventilation inverter, the following steps (1) to (6) may be performed:
(1) when the temperature information is larger than a first temperature threshold value, determining a first ventilation volume corresponding to the temperature information, and determining a first voltage value and a first voltage frequency of the voltage output by the emergency ventilation inverter to the waste discharge device according to the first ventilation volume;
(2) generating a voltage control command of the emergency ventilation inverter using the first voltage value and the first voltage frequency and transmitting the voltage control command to the emergency ventilation inverter so that the emergency ventilation inverter outputs a voltage having a first voltage value and a first voltage frequency to the waste device;
(3) when the temperature information is smaller than or equal to a first temperature threshold and larger than or equal to a second temperature threshold, determining a second ventilation volume corresponding to the temperature information, and determining a second voltage value and a second voltage frequency of the voltage output by the emergency ventilation inverter to the waste discharge device according to the second ventilation volume;
(4) generating a voltage control command of the emergency ventilation inverter using the second voltage value and the second voltage frequency and transmitting the voltage control command to the emergency ventilation inverter so that the emergency ventilation inverter outputs a voltage having the second voltage value and the second voltage frequency to the waste device;
(5) when the temperature information is smaller than a second temperature threshold value, determining a third ventilation volume corresponding to the temperature information, and determining a third voltage value and a third voltage frequency of the voltage output by the emergency ventilation inverter to the waste discharge device according to the third ventilation volume;
(6) generating a voltage control command of the emergency ventilation inverter using the third voltage value and the third voltage frequency and transmitting the voltage control command to the emergency ventilation inverter so that the emergency ventilation inverter outputs a voltage having a third voltage value and a third voltage frequency to the waste device;
wherein the first voltage value, the second voltage value and the third voltage value are all smaller than the rated working voltage of the waste discharge device.
In the step (1), the first temperature threshold is cached in the air conditioner controller.
In one embodiment, the first temperature threshold may be set to any temperature value between 12 degrees celsius and 25 degrees celsius, and optionally, the first temperature threshold may be set to 15 degrees celsius.
In one embodiment, the first correspondence relationship between the temperature range and the ventilation volume of each temperature threshold value component can be expressed as follows:
the temperature information is greater than a first temperature threshold value and a first ventilation volume
The temperature information is less than or equal to the first temperature threshold and greater than or equal to the second temperature threshold and the second ventilation volume
Third ventilation volume with temperature information smaller than second temperature threshold
The first ventilation rate is greater than the second ventilation rate and the third ventilation rate, and the second ventilation rate is greater than the third ventilation rate.
Alternatively, in one embodiment, the first ventilation rate may be set to 10.8 cubic meters per hour, the second ventilation rate may be set to 8.4 cubic meters per hour, and the third ventilation rate may be set to 7.5 cubic meters per hour.
The first ventilation volume and the second ventilation volume can be set, and the third ventilation volume can also be set to other numerical values, which are not described in detail herein.
Therefore, when the air conditioning controller determines that the temperature information is greater than the first temperature threshold, it is determined from the first correspondence that the waste drain device should perform the ventilating operation in the vehicle compartment at the first ventilation amount.
Then, based on the first ventilation amount, a first voltage value and a first voltage frequency of an output voltage of the emergency ventilation inverter to the waste discharge device are determined.
In order to determine a first voltage value and a first voltage frequency of the voltage output by the emergency ventilation inverter to the waste discharge device based on the first ventilation quantity, the air conditioner controller also stores a corresponding relation among the first ventilation quantity, the first voltage value and the first voltage frequency; the corresponding relation among the second ventilation volume, the second voltage value and the second voltage frequency; and the corresponding relation among the third ventilation volume, the third voltage value and the third voltage frequency.
Therefore, the air conditioner controller inquires the corresponding relation among the first ventilation volume, the first voltage value and the first voltage frequency, wherein the first ventilation volume, the first voltage value and the first voltage frequency are provided with the first ventilation volume, and determines the first voltage value and the first voltage frequency of the voltage output by the emergency ventilation inverter to the waste discharge device from the inquired corresponding relation among the first ventilation volume, the first voltage value and the first voltage frequency.
Here, the correspondence of the first ventilation amount, the first voltage value, and the first voltage frequency; the corresponding relation among the second ventilation volume, the second voltage value and the second voltage frequency; and the corresponding relation among the third ventilation volume, the third voltage value and the third voltage frequency can be obtained by testing the voltage value and the voltage frequency output by the emergency ventilation inverter when the first ventilation volume, the second ventilation volume and the third ventilation volume are tested respectively. After the test is finished, the obtained corresponding relation among the first ventilation volume, the first voltage value and the first voltage frequency can be obtained; the corresponding relation among the second ventilation volume, the second voltage value and the second voltage frequency; and storing the corresponding relation among the third ventilation volume, the third voltage value and the third voltage frequency into the air conditioner controller.
In one embodiment, the first voltage value may be set to 345 volts ac and the first voltage frequency may be set to 40 hertz.
In the step (2), the air conditioner controller stores a second correspondence relationship between the voltage value and the frequency value, and the level of the first inverter start signal and the level of the second inverter start signal.
In one embodiment, the second corresponding relationship may be expressed as follows:
a high level signal (level of the first inverter start signal) of 345V (first voltage value) 40 Hz (first voltage frequency) and a low level signal (level of the second inverter start signal)
Low level signal (level of first inverter start signal) of low level (level of second inverter start signal) of 30 Hz (second voltage frequency) of alternating current 259V (second voltage value)
High level signal (level of first inverter start signal) of high level signal (level of second inverter start signal) of 20 Hz (third voltage frequency) of 172.5V (third voltage value) of alternating current
In the second corresponding relationship, the first voltage value, the first voltage frequency, the second voltage value, the second voltage frequency, the third voltage value, and the third voltage frequency may also be set to other values, which is not described herein.
Therefore, when it is determined that the emergency ventilation inverter should output the voltage having the first voltage value and the first voltage frequency to the waste discharge device, the air conditioner controller may inquire of the second correspondence relationship that a high level signal, which is a first inverter start signal, should be transmitted to the B1 pin of the emergency ventilation inverter, and simultaneously transmit a low level signal, which is a second inverter start signal, to the B2 pin, so that when the emergency ventilation inverter receives the first inverter start signal of the high level and the second inverter start signal of the low level, which are voltage control commands, the emergency ventilation inverter performs internal logic processing on the first inverter start signal of the high level and the second inverter start signal of the low level, and then outputs the voltage having the first voltage value and the first voltage frequency to the waste discharge device.
The specific processes of controlling the emergency ventilation inverter to output the second voltage value and the second voltage frequency of the voltage to the waste discharge device, which are described in the above steps (3) to (4), and the specific processes of controlling the emergency ventilation inverter to output the third voltage value and the third voltage frequency of the voltage to the waste discharge device, which are described in the above steps (5) to (6), are similar to the specific processes of controlling the emergency ventilation inverter to output the first voltage value and the first voltage frequency of the voltage to the waste discharge device, which are described in the above steps (1) to (2), and are not described again here.
In the step (3), the second temperature threshold is cached in the air conditioner controller.
In an embodiment, the first temperature threshold may be set to any temperature value between-3 degrees celsius and 3 degrees celsius, and optionally, the second temperature threshold may be set to 0 degrees celsius.
It can be seen from the above contents of steps (1) to (6) that the air conditioner controller can not only control the waste discharge device to perform ventilation operations with different ventilation volumes in the carriage according to different temperature information, but also control the emergency ventilation inverter to output a voltage lower than the rated operating voltage to the waste discharge device, thereby reducing the power consumption of the waste discharge device and improving the service life of the storage battery.
The embodiment also provides a railway vehicle. Comprises the waste discharge device control system.
In summary, in the exhaust device control system and the rail vehicle provided in this embodiment, the air conditioning controller determines the ventilation volume of the exhaust device according to the acquired current temperature information outside the vehicle compartment, determines and generates the voltage control command of the emergency ventilation inverter according to the ventilation volume of the exhaust device, and sends the voltage control command to the emergency ventilation inverter, so that the emergency ventilation inverter outputs the voltage indicated by the voltage control command to the exhaust device, so that the exhaust device performs the ventilation operation in the vehicle compartment of the rail vehicle under the control of the voltage output by the emergency ventilation inverter, and compared with the manner in the related art that the ventilation volume of the exhaust device is larger in the emergency ventilation state, so as to affect the comfort level of passengers riding the rail vehicle, the ventilation volume of the exhaust device can be determined according to the current temperature information outside the vehicle compartment, and the ventilation volume in the vehicle compartment can be reduced as much as possible, the comfort level of passengers in the carriage on the rail vehicle is improved.
