In the current fast-paced social environment, rail transit trains play an increasingly important role in our lives, and a Central Control Unit (CCU) of the trains is used as the working brain of normal operation of the trains, and if the CCU breaks down, the trains lose Control, so that the safety of passengers cannot be guaranteed. Therefore, ensuring the normal operation of the CCU is one of the important factors for ensuring the normal operation of the train. At present, most rail transit vehicles have a dual-machine hot standby redundancy function, namely, under a normal working condition, the rail transit vehicles comprise a strong main control CCU and a weak main control CCU. However, when a train is in operation, if any one of the strong main CCU and the weak main CCU has a fault, such as a hardware fault circuit of the strong main CCU and the weak main CCU is damaged, or program software has a fault due to data overflow or array boundary crossing breakdown, or a CCU fault is caused by unstable power supply voltage or power failure, the CCU cannot calculate the operation time length, so that the operation time lengths calculated by the strong main CCU and the weak main CCU are inconsistent, and the operation time lengths sent to a train display screen (HMI) by the two CCU devices are inconsistent, thereby finally the accuracy of the actual operation time length of the train cannot be ensured.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making an invasive task, are within the scope of the present invention.
The train running time processing method provided by the embodiment of the invention can be applied to the application environment shown in fig. 1. Specifically, the train operation duration processing method is applied to a train operation duration processing system, the train operation duration processing system comprises a first central control unit and a second central control unit shown in fig. 1, and the first central control unit and the second central control unit are communicated through a network and used for achieving the problem that the operation duration of a train is inaccurate. The first central control unit and the second central control unit are working brains of the train in normal operation and can be used for calculating the operation time of the train before starting. The first central control unit and the second central control unit can monitor the heartbeat and the working state of the other party mutually.
In an embodiment, as shown in fig. 2, a train operation duration processing method is provided, which is described by taking the first central control unit in fig. 1 as an example, and includes the following steps:
s10: before the train is started, the first central control unit periodically acquires a first operation time length and a second operation time length, wherein the first operation time length is the operation time length calculated and stored by the first central control unit, and the second operation time length is the operation time length calculated and stored by the second central control unit matched with the first central control unit.
Specifically, before the train starts, the first central control unit periodically acquires the first operation time length and the second operation time length. Alternatively, when the vehicle speed of the train is less than a preset threshold (for example, 0.2 km/h) and the traction enable of the train is invalid, it is determined that the train has not been started. The periodically acquiring the first operation duration and the second operation duration means that the first central control unit acquires the first operation duration and the second operation duration according to a preset time interval if the train is not started after comparing the acquired first operation duration and the acquired second operation duration and confirming the current operation duration, and the operation is circulated in sequence until the train is started. It will be appreciated that after power up, the first central control unit will always read the first operating time period stored by its own calculation and the second operating time period stored by the second central control unit as long as the speed of the train has not been greater than 0.2km/h and no traction enable.
The first operation duration is the operation duration calculated and stored by the first central control unit, and the second operation duration is the operation duration calculated and stored by the second central control unit matched with the first central control unit. In a specific embodiment, the train includes two Central Control Units (CCUs), one of which is a strong main control central control unit and the other is a weak main control central control unit under normal working conditions, the two central control units can monitor the heartbeat and working state of each other, and the heartbeat and working state between the two central control units can be transmitted through an ethernet packet. When the strong main control central control unit fails, another weak main standby central control unit can replace the failed weak main standby central control unit. The train only needs one central control unit to work normally to maintain normal operation, and the other central control unit is in a standby state. In this embodiment, the first central control unit and the second central control unit are mutually matched, one is used as a strong main control central control unit, and the other is used as a weak main standby central control unit.
S20: the first central control unit updates the first operation duration by using a larger value of the first operation duration and the second operation duration.
Specifically, before the train is started, the first central control unit compares the acquired first operation duration with the acquired second operation duration, and if the first operation duration is longer than the second operation duration, the first operation duration is used as the current first operation duration of the first central control unit, and records are stored; and if the first operation duration is shorter than the second operation duration, taking the second operation duration as the current first operation duration of the first central control unit, and storing a record, so as to realize that the first operation duration of the first central control unit is updated by adopting a larger value in the first operation duration and the second operation duration.
In one embodiment, since the train includes two central control units: the first central control unit and the second central control unit work in a matched mode, so that when the first central control unit updates the first operation time length by adopting a larger value of the first operation time length and the second operation time length, the second central control unit reads the first operation time length calculated and stored by the second central control unit and the second operation time length calculated and stored by the first central control unit, compares the first operation time length calculated and stored by the second central control unit with the second operation time length calculated and stored by the first central control unit, and if the first operation time length is larger than the second operation time length, the first operation time length is used as the current first operation time length of the second central control unit and records are stored; and if the first operation time length is less than the second operation time length, taking the second operation time length as the current first operation time length of the second central control unit, and storing the record. In the next communication period, the first central control unit and the second central control unit repeat the operation, mutually compare the values of the first running time length and the second running time length, and always read a larger value as the current second running time length; therefore, the running time lengths calculated and processed by the first central control unit and the second central control unit can be always kept consistent, and the purpose of synchronizing the running time lengths of the double Central Control Units (CCUs) is achieved.
S30: after the train is started, if the running state of the first central control unit is a strong main state, the first central control unit sends a real-time first running time to a train display screen.
Specifically, after the train is started, the first central control unit and the second central control unit stop running for a time period to be synchronous, and if the running state of the first central control unit is a strong master state, the first central control unit sends a real-time first running time period to a train display screen for reference of an operator. Alternatively, when the speed of the train is greater than a preset threshold (for example, 0.2 km/h) and the traction enable of the train is effective, it is determined that the train is started.
In another embodiment, after the train is started, if the operation state of the second central control unit is a strong master state, the second central control unit sends the real-time first operation duration to the train display screen for the operator to refer.
In this embodiment, before a train is started, a first central control unit periodically obtains a first operation duration and a second operation duration, where the first operation duration is an operation duration calculated and stored by the first central control unit, and the second operation duration is an operation duration calculated and stored by a second central control unit that is matched with the first central control unit; the first central control unit updates the first operation time length by adopting the larger value of the first operation time length and the second operation time length; after the train is started, if the running state of the first central control unit is a strong main state, the first central control unit sends real-time first running duration to a train display screen; the embodiment can synchronize the running time before the train is started, and synchronize the stopping running time after the train is started, so that the running time variables do not need to be mutually acquired in real time in the running process of the train, calculation and assignment are carried out, and the program load rate and the occupancy rate can be effectively reduced; in addition, the running time is synchronized, so that the problem that the running time of the train is inaccurate due to the fact that the train time calculated by the first central control unit is inconsistent with the train time calculated by the second central control unit is solved, and the phenomenon that the running time of the train display screen is reversed or added is avoided.
In an embodiment, as shown in fig. 3, the method for processing the train operation duration further includes the following steps:
s11: and if the running state of the first central control unit is the weak master state, monitoring the running state of the second central control unit in real time.
S12: if the operating state of the second central control unit is changed to the weak master state, the operating state of the first central control unit is changed to the strong master state.
Specifically, because the train includes two Central Control Units (CCUs), under normal working conditions, one is used as a strong main control central control unit, the other is used as a weak main control central control unit, and the two central control units can monitor the heartbeat and working state of the other side mutually. Therefore, before the train is started and after the first central control unit and the second central control unit are powered on and initialized, if the operation state of the first central control unit is in the weak master state and the second central control unit is in the strong master state, the first central control unit monitors the operation state of the second central control unit in real time, and if the operation state of the second central control unit is detected to be changed into the weak master state, for example: when the second central control unit fails, the first central control unit changes the operation state of the first central control unit into a strong main state, and the second central control unit changes the operation state of the second central control unit into a weak main state.
It can be understood that, the first central control unit and the second central control unit monitor the working state of each other, and when the running state of the second central control unit is the strong master state, the running state of the first central control unit is the weak master state; if the operation state of the second central control unit is changed into the weak master state, the operation state of the first central control unit is changed into the strong master state; therefore, only one central control unit on the train is required to work normally to maintain normal operation, and the other central control unit is in a standby state.
In this embodiment, if the operating status of the first central control unit is the weak master status, the operating status of the second central control unit is monitored in real time; if the operation state of the second central control unit is changed into a weak main state, changing the operation state of the first central control unit into a strong main state; the method ensures that only one central control unit on the train works normally to maintain normal operation, and the other central control unit is in a standby state, thereby saving equipment resources while ensuring the accuracy of the obtained train operation time.
In an embodiment, as shown in fig. 4, after the train is started, the train operation duration processing method further includes the following steps:
s31: and acquiring the crystal oscillation frequency of the first central control unit.
Here, the crystal oscillation frequency refers to a time interval (cycle) at which any oscillation (oscillation) phenomenon repeatedly occurs. Specifically, after the first central control unit completes initialization and completes synchronization of the running time with the second central control unit, if the train speed is greater than 0.2km/h and the control handle is at the traction position, the first central control unit collects the crystal oscillator vibration frequency inside the equipment and performs cumulative number calculation, and the cumulative number is converted into time duration cumulative.
S32: and calculating the accumulated operation time length of the first central control unit according to the crystal oscillation frequency accumulation.
Specifically, the calculating the accumulated operating time period of the first central control unit according to the crystal oscillation frequency accumulation includes: the obtained crystal oscillator vibration frequency is firstly subjected to accumulated frequency calculation, then the crystal oscillator vibration frequency is converted into crystal oscillator time length, and finally the crystal oscillator time length is converted into the accumulated running time length of the first central control unit. In the present embodiment, the conversion of the crystal oscillation frequency into the crystal oscillation time length is realized by converting every 20 clock cycles of the crystal oscillation frequency into 1 s. In the process of converting the crystal oscillator time length into the accumulated operation time length, when the crystal oscillator time length is accumulated to 60 seconds, accumulating the minutes of the accumulated operation time length by adding 1, and when the crystal oscillator time length is not accumulated to 60 seconds, accumulating the accumulated operation time length according to a 50ms period, but not using the data; when the crystal oscillator time length is accumulated to 60 minutes, adding 1 to the accumulated operation hours of the accumulated operation time length, when the crystal oscillator time length is not accumulated to 60 minutes, still accumulating the crystal oscillator time length according to a 50ms period, accumulating the operation minutes when the crystal oscillator time length exceeds 60 seconds, and not processing when the crystal oscillator time length is less than 60 seconds.
S33: and when the accumulated operation time of the first central control unit meets a preset value, sending the accumulated operation time of the first central control unit to a train display screen for displaying.
The preset value is a preset value for detecting whether the accumulated operation time meets the display condition. In this embodiment, the advance value may be one or more, for example: the advance value may be 60 seconds, 60 minutes, etc. Specifically, if the preset value is 60 seconds, when the accumulated operation time of the first central control unit is greater than or equal to 60 seconds, it indicates that the accumulated operation time of the first central control unit meets the preset value, adds 1 to the number of minutes of the accumulated operation time, and sends the accumulated operation time of the first central control unit to the train display screen for displaying. If the accumulated running time is less than 60 seconds, accumulation is continued, but the accumulated running time is not sent to a display screen. Similarly, if the preset value is 60 minutes, when the number of minutes of the accumulated operation time length is greater than or equal to 60 minutes, the number of hours of the accumulated operation time length is added by 1, and the accumulated operation time length of the first central control unit is sent to a train display screen for displaying. If the accumulated minutes are less than 60 minutes, keeping the accumulated minutes of the accumulated operation time length, and sending the accumulated operation time length of the first central control unit to a train display screen for displaying in the form of minutes; therefore, the train display screen can normally and accurately display the actual running time of the train.
In the embodiment, the crystal oscillation frequency of the first central control unit is obtained; calculating the accumulated operation time of the first central control unit according to the crystal oscillator vibration frequency accumulation; when the accumulated operation time of the first central control unit meets a preset value, the accumulated operation time of the first central control unit is sent to a train display screen to be displayed; therefore, the running time accuracy of the display screen of the train is further improved, and more accurate reference is provided for the service life or the replacement time of the steel wheel or the rubber wheel.
In an embodiment, as shown in fig. 5, the preset values include a first preset value and a second preset value, and when the accumulated operating time of the first central control unit meets the preset values, the accumulated operating time of the first central control unit is sent to a train display screen for displaying, which specifically includes the following steps:
s331: and when the accumulated operation time of the first central control unit meets a first preset value, sending the accumulated operation time of the first central control unit to a train display screen for displaying.
S332: and when the accumulated operation time of the first central control unit meets a second preset value, sending the accumulated operation time of the first central control unit to a train display screen for displaying.
Specifically, referring to fig. 6, if the train speed is greater than 0.2km/h and the control handle is at the traction position, the first central control unit collects the vibration frequency of the crystal oscillator inside the equipment and performs cumulative number calculation, and the crystal oscillator starts to count time and adds 1s every 20 timing cycles, so as to convert the time into cumulative operation duration. Referring to fig. 6, the first preset value is preferably 60 seconds, when the accumulated operating time of the first central control unit is greater than or equal to 60 seconds, it indicates that the accumulated operating time of the first central control unit meets the first preset value, 1 is added to the number of minutes of the accumulated operating time, and the accumulated operating time of the first central control unit is sent to the train display screen for displaying. The second preset value is preferably 60 minutes; and when the number of minutes of the accumulated operation time length is greater than or equal to 60 minutes, adding 1 to the number of hours of the accumulated operation time length, and sending the accumulated operation time length of the first central control unit to a train display screen for displaying.
In an embodiment, as shown in fig. 7, a method for processing train operation duration is provided, which is described by taking the application of the method to the train operation duration system in fig. 1 as an example, and includes the following steps:
and S100, before the train is started, determining a first operation state of a first central control unit and a second operation state of a second central control unit.
Specifically, referring to fig. 8, before the train starts, a first operation state of the first central control unit and a second operation state of the second central control unit are determined. Alternatively, when the speed of the train is less than a preset threshold (illustratively, 0.2 km/h) and the traction enable of the train is invalid, it is determined that the train has not been started.
In a specific embodiment, when the first central control unit and the second central control unit are not powered on, the status bits of the first central control unit and the second central control unit are defaulted to be 0, and the first central control unit and the second central control unit are indicated to not start to operate; when the first central control unit and the second central control unit are just powered on, the status bits of the first central control unit and the second central control unit are 1, and the first central control unit and the second central control unit are indicated to be in an initialization state; after the first central control unit and the second central control unit are initialized, determining a first operation state of the first central control unit and a second operation state of the second central control unit according to the power-on time; if the power-on time of the first central control unit is earlier than the power-on time of the second central control unit, setting the state bit of the first central control unit to be 3 to indicate that the running state of the first central control unit is in a strong main state, and setting the state bit of the second central control unit to be 2 to indicate that the running state of the second central control unit is in a weak main state; if the power-on time of the first central control unit is later than the power-on time of the second central control unit, setting the status bit of the second central control unit to be 3 to indicate that the operation state of the second central control unit is a strong master state, and setting the status bit of the first central control unit to be 2 to indicate that the operation state of the first central control unit is a weak master state.
Additionally, when the central control unit with the operation state of strong master fails, the central control unit with another operation state of weak master can take over the central control unit with strong master, that is, the operation state of the central control unit with the failed strong master changes to the weak master, and the operation state of the central control unit with the weak master changes to the strong master.
And S101, the first central control unit periodically acquires a first operation time length and a second operation time length, wherein the first operation time length is the operation time length calculated and stored by the first central control unit, and the second operation time length is the operation time length calculated and stored by the second central control unit matched with the first central control unit.
And S102, the first central control unit updates the first operation time length by adopting the larger value of the first operation time length and the second operation time length.
Specifically, referring to fig. 8, the first central control unit periodically obtains a first operating time period T1 calculated and stored by itself from the first central control unit and a second operating time period T2 calculated and stored by the second central control unit; and comparing a first operating duration T1 of the first central control unit with a second operating duration T2 of the second central control unit; if the first operation time length T1 of the first central control unit is longer than the second operation time length T2 of the second central control unit, determining the first operation time length T1 of the first central control unit as the current first operation time length T1 of the first central control unit, and storing a record; and if the first operation time length T1 of the first central control unit is less than the second operation time length T2 of the second central control unit, determining the second operation time length T2 of the second central control unit as the current first operation time length T1 of the first central control unit, and storing the record. In the next communication period, the first central control unit repeats the operation, compares the values of the first operation time length and the second operation time length with each other, and always reads the larger value as the current first operation time length; therefore, the running time lengths calculated and processed by the first central control unit and the second central control unit can be always kept consistent, and the purpose of synchronizing the running time lengths of the double Central Control Units (CCUs) is achieved.
S103, the second central control unit periodically acquires the first operation time length and the second operation time length.
And S104, updating the second operation time length by the second central control unit by adopting the larger value of the first operation time length and the second operation time length.
Specifically, referring to fig. 8, the second central control unit periodically obtains the second operating time length T2 calculated and stored by itself from the second central control unit and the first operating time length T1 calculated and stored by the first central control unit; and comparing the first operating duration T2 of the second central control unit with the first operating duration T1 of the first central control unit; if the second operation time length T2 of the second central control unit is longer than the first operation time length T1 of the second central control unit, determining the second operation time length T2 of the second central control unit as the current second operation time length T1 of the second central control unit, and storing a record; if the second operation duration T2 of the second central control unit is less than the first operation duration T1 of the first central control unit, the first operation duration T1 of the first central control unit is determined as the current second operation duration T2 of the second central control unit, and a record is stored. In the next communication period, the second central control unit repeats the operation, compares the values of the first operation duration and the second operation duration with each other, and reads a larger value as the current second operation duration all the time; therefore, the running time lengths calculated and processed by the first central control unit and the second central control unit can be always kept consistent, and the purpose of synchronizing the running time lengths of the double Central Control Units (CCUs) is achieved.
S105, after the train is started, if the first running state of the first central control unit is a strong main state, the first central control unit sends real-time first running time of the first central control unit to a train display screen; and if the second running state of the second central control unit is a strong main state, the second central control unit sends the real-time second running time of the second central control unit to the train display screen.
Specifically, referring to fig. 8, after the train is started, if the first operating state of the first central control unit is the strong master state, the first central control unit sends the real-time first operating duration of the first central control unit to the train display screen; and if the second running state of the second central control unit is the strong main state, the second central control unit sends the real-time second running time of the second central control unit to a train display screen for the reference of operators. Optionally, when the speed of the train is greater than a preset threshold (for example, 0.2 km/h) and the traction enable of the train is valid, the train is determined to be started.
In the embodiment, before the train is started, a first operation state of a first central control unit and a second operation state of a second central control unit are determined; the method comprises the steps that a first central control unit periodically obtains a first operation time length and a second operation time length, wherein the first operation time length is calculated and stored by the first central control unit, and the second operation time length is calculated and stored by a second central control unit matched with the first central control unit; the first central control unit updates the first operation duration by adopting the larger value of the first operation duration and the second operation duration; the second central control unit periodically acquires a first operation time length and a second operation time length; the second central control unit updates the second operation time length by adopting the larger value of the first operation time length and the second operation time length; after the train is started, if the first running state of the first central control unit is a strong main state, the first central control unit sends real-time first running duration of the first central control unit to a train display screen; if the second running state of the second central control unit is a strong main state, the second central control unit sends real-time second running duration of the second central control unit to a train display screen; the embodiment can synchronize the running time before the train is started and stop the running time after the train is started, thereby ensuring that the running time variables do not need to be mutually acquired in real time in the running process of the train, calculating and assigning values, and effectively reducing the program load rate and the occupancy rate; in addition, the running time is synchronized, so that the problem that the running time of the train is inaccurate due to the fact that the train time calculated by the first central control unit is inconsistent with the train time calculated by the second central control unit is solved, and the phenomenon that the running time of a train display screen is reversed or added is avoided.

Specifically, when the first central control unit and the second central control unit are not powered on, the status bits of the first central control unit and the second central control unit are defaulted to be 0, and the first central control unit and the second central control unit are indicated to not start to operate; when the first central control unit and the second central control unit are just powered on, the status bits of the first central control unit and the second central control unit are 1, and the first central control unit and the second central control unit are indicated to be in an initialization state.
In one embodiment, in order to determine the operating states of the first central control unit and the second central control unit, after the first central control unit is initialized, the power-on time of the first central control unit and the second central control unit is monitored, if the power-on time of the first central control unit is earlier than the power-on time of the second central control unit, the operating state of the first central control unit is set as a strong master state, and the operating state of the second central control unit is set as a weak master state; and if the power-on time of the first central control unit is later than that of the second central control unit, setting the running state of the first central control unit as a weak master state, and setting the running state of the second central control unit as a strong master state. It is to be understood that, after the two central control units are initialized, the operating state of the central control unit with the earlier power-on time is determined as the strong master state, and the operating state of the central control unit with the later power-on time is determined as the weak master state.
In this embodiment, after the first central control unit is initialized, the first central control unit and the second central control unit are monitored; if the power-on time of the first central control unit is earlier than that of the second central control unit, setting the running state of the first central control unit to be in a strong main state, and setting the running state of the second central control unit to be in a weak main state; therefore, only one central control unit on the train is required to work normally to maintain normal operation, and the other central control unit is in a standby state, so that equipment resources are saved.
