As shown in fig. 1 to 3, some embodiments of the present invention disclose a method for controlling remote automatic start and stop of a diesel engine of a diesel locomotive, including:
firstly, a driver sends a reconnection starting command signal to a main control unit of a lead locomotive 1;
secondly, after receiving the reconnection instruction signal, the main control unit of the lead locomotive 1 transmits the reconnection instruction signal to a first wired reconnection locomotive 2 through a reconnection cable, and transmits the reconnection instruction signal to a wireless reconnection locomotive 3 through wireless transmission equipment;
after the wireless reconnection locomotive 3 and the first wired reconnection locomotive 2 receive the reconnection tripping instruction signal, tripping condition judgment is carried out on the diesel engine of the locomotive, and the diesel engine is directly started if the condition is met.
In the embodiment, the lead locomotive 1 sends a reconnection locomotive instruction signal, and the instruction signal is sent to the wired reconnection locomotive and the wireless reconnection locomotive 3 through a wired and wireless transmission method, so that remote starting control over diesel engines of the wired reconnection locomotive and the wireless reconnection locomotive 3 is realized, wherein the first wired reconnection locomotive 2 in the embodiment refers to a wired reconnection locomotive directly connected with the lead locomotive 1 through a reconnection cable.
On the basis of the above embodiments, in the second step, after the wireless reconnection locomotive 3 receives the reconnection start instruction signal, the reconnection start instruction signal is transmitted to the second wired reconnection locomotive 4 through a reconnection cable, and after the second wired reconnection locomotive 4 receives the reconnection start instruction signal, the start condition judgment is performed on the diesel engine of the locomotive, and if the condition is met, the diesel engine is directly started.
On the basis of the previous embodiment, the present embodiment further realizes remote control of the wired reconnection locomotive in wired reconnection with the wireless reconnection locomotive 3. The second wired multi-locomotive 4 in the present embodiment refers to a wired multi-locomotive on the wireless multi-locomotive 3 that is not directly connected to the lead locomotive 1, but is directly connected by a multi-locomotive cable. And performing remote diesel engine starting control on a second wired multi-locomotive 4 directly connected with the wireless multi-locomotive 3 through a wired multi-locomotive cable by taking the wireless multi-locomotive 3 as a new control starting point.
On the basis of the above embodiments, in the second step, the transmitting the reconnection start instruction signal to the wireless reconnection locomotive 3 through the wireless transmission device includes: the remote transmission equipment of the lead locomotive 1 transmits the reconnection engine starting instruction signal to the remote transmission equipment of the wireless reconnection locomotive 3, and the remote transmission equipment of the wireless reconnection locomotive 3 sends the reconnection engine starting instruction signal to the main control unit of the wireless reconnection locomotive 3 through a data communication bus after receiving the reconnection engine starting instruction signal.
In the first step, the sending a reconnection start command signal to a main control unit of a lead locomotive comprises: the method comprises the steps of acquiring command signals through a hardware circuit, converting the acquired command signals into digital signals through an input module, and sending the digital signals to a master control unit of the lead locomotive through a locomotive data communication bus.
The step of acquiring the command signal through the hardware circuit comprises the step of acquiring a direction handle signal of the lead locomotive as the command signal. That is, the recloser command signal used in the present invention may use the driver direction handle signal because it is already included in both the standard wired and wireless recloser data and no new signal needs to be added. And the driver must operate the direction handle to set the locomotive running direction before operating the locomotive, and at the moment, if any locomotive diesel engine in the double-locomotive stops due to the automatic stop function, the diesel engine can be immediately started when receiving the direction handle signal of the lead locomotive. This means that the engineer is able to put all of the locomotives in the entire consist into service without any additional operations.
For the signal communication process, the operation of the operator on the command signal of the duplicate crane is only carried out on the lead locomotive, so the signal acquisition is finished by the lead locomotive; the remote wireless reconnection locomotive is also used as a master control locomotive in a remote marshalling, so the signal sending work is jointly completed by the lead locomotive and the remote wireless reconnection locomotive; all the multi-locomotive is responsible for receiving the communication signals sent by the lead locomotive and carrying out validity check on the signals.
For signal acquisition, a command signal of the lead locomotive reconnection is acquired through a hardware circuit, and the acquired signal is converted into a digital signal through an input module and is transmitted into a locomotive main control unit through a locomotive data communication bus.
For signal transmission, after receiving a reconnection engine starting instruction signal, the main control unit of the lead locomotive converts a digital signal into an electric signal through an output module, and then transmits the electric signal to a locomotive which uses a reconnection cable for reconnection through a locomotive reconnection cable; meanwhile, the reconnection engine starting command signal is sent to wireless remote transmission equipment through a data communication bus and then transmitted to a remote wireless reconnection locomotive in a remote communication mode. After receiving the signal, the remote transmission equipment of the wireless reconnection locomotive sends the signal to the main control unit through the data communication bus, and then the signal is sent to the reconnection cable through the output module by the main control unit.
For signal reception, the lead locomotive is responsible for receiving command signals from the lead locomotive. Firstly, judging a reconnection mode by a locomotive microcomputer system, if the locomotive is wired reconnection, enabling a reconnection engine starting command electric signal obtained from a reconnection cable to enter a remote input module, converting the reconnection engine starting command electric signal into a digital signal, and then entering a main control unit through a data communication bus; if the locomotive is in wireless reconnection, the remote wireless transmission equipment receives a reconnection locomotive instruction signal transmitted from the lead locomotive and transmits the signal to the main control unit through the data communication bus.
On the basis of the embodiments, the method for controlling the remote automatic start-stop of the diesel engine of the diesel locomotive disclosed by some embodiments of the invention comprises the following steps of:
step three, detecting whether the state of the diesel engine of the locomotive meets the advanced condition;
if the early condition is met, skipping over the automatic starting condition of the diesel engine, and judging whether the diesel engine of the locomotive meets the starting condition; and if the diesel engine of the locomotive does not meet the starting condition, ending the operation.
And step five, if the starting condition is met, directly starting the diesel engine.
Wherein, whether the diesel engine state that detects this locomotive satisfies the antecedent condition includes:
judging the current state of the diesel engine, and if the current state of the diesel engine is running, ending;
if the current state of the diesel engine is a stop state and the diesel engine stops due to the automatic stop function, considering that the prior condition is met, and entering the next step;
and if the current state of the diesel engine is a stop state but the diesel engine is not stopped due to the automatic stop function, the diesel engine is considered not to meet the prior condition, and the operation is finished.
The automatic starting condition of the diesel engine is an automatic starting condition in the automatic starting and stopping control of the diesel engine, such as too low external environment temperature, too low diesel engine temperature, too low locomotive wind pressure and the like; the starting condition of the diesel engine is whether the current state parameter of the diesel engine allows starting, such as whether the cooling water level of the diesel engine is above the safe water level, whether the engine oil of the diesel engine is sufficient, whether a fault occurs and the like.
In the second step, the reconnection locomotive judges the reconnection mode, if the reconnection mode is wired reconnection, an electric signal of a reconnection locomotive instruction is obtained from a reconnection cable, and the electric signal is converted into a digital signal and then enters a main control unit of the locomotive through a data communication bus; if the locomotive is in wireless reconnection, the remote wireless transmission equipment receives the digital signal of the reconnection starting instruction and transmits the digital signal to the main control unit of the locomotive through a data communication bus.
In the above embodiment, the auto-start function of the diesel engine of the multi-locomotive is limited to the diesel engine stopped by the auto-stop function, and if the diesel engine is stopped by a fault or manually, the auto-start function is blocked. Therefore, the reason for the shutdown of the diesel engine needs to be determined in the main control unit control logic. The multi-locomotive is also required to judge whether the current locomotive multi-locomotive mode is wired multi-locomotive or wireless multi-locomotive, and then the source for receiving the signal of the lead locomotive is selected according to the multi-locomotive mode. After the reconnection locomotive receives a direction handle signal from the lead locomotive, the current diesel engine state is judged firstly, if the current diesel engine is in a stop state and is stopped due to an automatic stop function, the condition judgment and waiting time of automatic start-up is skipped, whether the diesel engine meets the start-up condition at present is directly detected, and if the condition is met, the diesel engine is directly started.
In the embodiment of the invention, how to judge that the diesel engine stops due to automatic stop is the basis for realizing the function. This determination needs to be done in the master control unit of each locomotive. When the main control unit of the multi-locomotive controls the diesel engine to automatically stop, an automatic stop completion mark needs to be arranged in software, wherein the mark is set to be '1' after the whole automatic stop process of the diesel engine is completed, and is set to be '0' after the diesel engine is started. The multi-locomotive can identify whether the locomotive is stopped due to the automatic stop function according to the mark.
After the reconnection locomotive receives the start command signal of the master locomotive, before starting the diesel engine, whether the current diesel engine state allows the start must be judged. The judgment conditions include, but are not limited to, the following conditions:
(a) whether the cooling water level of the diesel engine is above the safe water level or not;
(b) whether the diesel engine oil is sufficient;
(c) whether the diesel engine has serious faults which influence the starting of the diesel engine, such as crankshaft faults, particle faults and the like.
In conclusion, the invention controls the double-heading locomotive to automatically start the diesel engine through the starting command signal of the lead locomotive, and sends the starting command to all the double-heading locomotives through the double-heading cable and remote data transmission. The automatic starting of the multi-locomotive can be directly controlled by an operator on the lead locomotive, the workload of the operator is reduced, the operability of the locomotive is improved, and the speed of the locomotive entering the running working condition is increased. Meanwhile, all functions of automatic stop of the diesel engine are reserved, and fuel consumption of the diesel engine is reduced.
