Locomotive lamp system energy saving control method

The invention relates to a method for energy-saving control of a locomotive lamp system, in particular to an energy-saving control method for a locomotive lamp system when the idling flameout state is applied.

The power generation mode of the locomotive lamp system is called the AC lighting at the earliest starting from the AC power supply of the generator, and the AC lighting generated by the generator is passed through the AC lighting. A voltage regulating circuit converts the alternating current power into a direct current power supply, and supplies the power to the locomotive light system, which is called a direct current lighting.

Under the development of the locomotive lamp system, in order to improve the safety of riding, the regulations have specific specifications for each lamp system, such as lumen value, area, angle, height, etc.

At the same time, the market began to produce higher and better requirements for the brightness of the headlights. In order to meet the requirements of the regulations and the market, the output specifications of the locomotive lamp system are relatively much improved, such as the headlight output specifications from the early 27 watts. The design is now 35 watts / 55 watts and the design of the double lamp is 70 watts / 110 watts. In response to the safety of riding lighting, in 2017 domestic regulations also regulate the requirements of full-time lighting.

In the face of such a high-powered lamp system, the power generation of the generator on the locomotive should also be increased at the same time to meet the power generation of the lamp system. According to tests conducted by the Energy Conservation Center, if the steam locomotive is running at idle speed, if the engine is turned off, it has the function of saving fuel consumption and reducing emissions. Subsequent major automakers have begun to develop idle-speed extinguishing devices. So far, domestic regulations have been regulated in 2018. According to the sales volume of different engine families, it is necessary to install an idle-speed extinguishing device.

Although the idling flame-extinguishing device has a certain contribution to fuel consumption and environmental protection, the biggest hidden worry behind it is that under the state of idling, the generator will stop running with the engine, and the power source of the lamp system and other loads on the locomotive will be generated. The supply of the motor is converted into the supply of the battery on the locomotive. After the engine is started, the generator starts to run. The source of the locomotive lamp and other load sources will be converted from the battery to the generator, and the generator will consume the battery under the idling stop. The energy is charged.

However, the hidden worry caused by this phenomenon is that under the condition of full-time lighting, the state of idling and flameout for a long time, such as urban traffic traffic lights and stop time is longer; in contrast, the energy of the battery is discharged under idle speed Full-time lighting causes a large amount of discharge; the energy of charging the battery depends on the speed and time of riding. If the metropolitan traffic ride time is not long, and the energy of charging is not enough to discharge energy, the battery is easy to cause the battery to be too low. Causes the engine to fail to start.

Because of this, in the spirit of active invention, this paper considers a method for energy-saving control of locomotive lamp system that can solve the above problems, and finally completes the present invention after several research experiments.

The main object of the present invention is to provide a locomotive lamp system energy-saving control method, which can detect the fuel signal sent by the injection engine, so that the control unit can directly obtain the digital signal of the fuel supply, without additionally adding an analog/digital signal conversion IC. The state of the idle speed is judged by taking the engine speed or the vehicle speed. Therefore, the present invention can achieve the detection and determination of the idle-stopping through a relatively simple circuit structure and less signal conversion processing, thereby solving the problem that the battery is too low due to the full-time lighting in the idle-off state, and the engine cannot be started smoothly. The subject.

To achieve the above object, the present invention provides a locomotive lamp system energy-saving control method for controlling the opening and closing of a lamp system, the lamp system comprising at least one large lamp and at least one safety lamp, the method comprising the following steps: A) After turning on a key switch, determine whether an engine has a start signal, and if so, perform step (C). If not, perform step (B); (B) an injection computer has no output fuel signal, triggering a large start The lamp energy-saving switch 21 and a safety light warning switch 22; (C) an injection computer starts the fuel system and performs step (D); (D) the injection computer outputs a fuel signal, triggers the off headlight energy-saving switch and the safety light warning switch, And step (E) is performed; (E) determining whether the engine is stopped, if not, repeating step (D), and if so, performing step (F); and (F) determining whether to close the key switch, and if so, the engine is stopped. , terminate the control process, if not, the engine idle stop temporarily stops, and return to step (A).

With the above design, the control unit located in the injection computer can detect whether the locomotive is in the idling or off state by detecting whether the blasting machine has an output fuel signal, thereby effectively reducing the setting of the conversion IC in the prior art, and reducing Cost overhead and improve transmission efficiency.

The triggering of the headlight energy-saving switch in the above step (B) may mean that the headlight is turned off, and the triggering of the start-up safety light warning switch may refer to turning the safety light on; in contrast, the triggering of the above step (D) is to turn off the headlight energy-saving relationship. The headlights are turned on, triggering to turn off the safety light. The warning on means that the safety light is turned off. Thereby, the headlights and the safety lights of the present invention are switched on by the headlight energy-saving switch and the safety light warning switch respectively in different states.

The safety light can be a brake light, which has a corresponding relationship with a brake line. Therefore, after the step (D) triggers the closing of the safety light warning switch, it further includes a step (D1) to determine whether a vehicle line is activated, and if so, The safety light can be turned on, if not, the safety light can be turned off. Therefore, when the engine is in the starting state, the brake light should return to the normal triggering mechanism, and it will cooperate with the braking line to act as the basis for starting or closing.

The above step (D) injecting the computer to output the fuel signal may mean triggering the opening of a fuel switch so that a fuel pump starts to operate. Among them, the fuel signal will cause the fuel switch to switch, and provide a power signal output as the fuel pump motor power to start the engine; otherwise, when there is no fuel signal, the fuel switch will be in the off state, the fuel pump can not be obtained The power signal is used as the motor power, so the engine will stop or enter the idle-off state, waiting for the timing to start again.

The above-mentioned headlight energy-saving switch, safety light warning switch and fuel switch can be respectively a relay. In this way, the switching of the signal path can be achieved through simple electronic components, thereby effectively reducing the cost and reducing the distortion caused by the signal conversion.

The above summary and the following detailed description are exemplary in order to further illustrate the scope of the invention. Other objects and advantages of the present invention will be described in the following description and drawings.

Please refer to FIG. 1 , which is a circuit diagram of an energy-saving control method for a locomotive lamp system according to a preferred embodiment of the present invention. In the circuit diagram shown in FIG. 1, the components associated with the present invention mainly include a group of injection computers 3, a fuel pump 4, a low beam lamp 11, a high beam lamp 12, and a safety light 13. Wherein, the fuel pump 4 controls whether the circuit is turned on or not by a fuel switch 41; similarly, the low beam lamp 11 and the high beam lamp 12 control whether the circuit is turned on or not by a large lamp energy-saving switch 21, and selects Similarly, the low beam 11 or the high beam 12 is turned on; similarly, the safety light 13 controls whether the circuit is turned on or not by a safety light warning switch 22. In addition, in the embodiment, the headlight energy-saving switch 21, the safety light warning switch 22, and the fuel switch 41 are respectively a relay. In this way, the switching of the signal path can be achieved through simple electronic components, thereby effectively reducing the cost and reducing the distortion caused by the signal conversion. Furthermore, another feature of the present invention is that the headlight energy-saving switch 21 and the safety light warning switch 22 are electrically connected to the circuit between the fuel switch 41 and the fuel pump 4, respectively, for detecting whether the injection computer has an output fuel signal. This makes the circuit smoothly turn on, and serves as a reference for whether to start the energy-saving switch. The following is based on the steps described below under the circuit architecture:

Please refer to FIG. 2, which is a flow chart of steps of an energy-saving control method for a locomotive lamp system according to a preferred embodiment of the present invention. The figure shows a method for energy saving control of a locomotive lamp system, and the steps include:

(A) After turning on a key switch, it is determined whether an engine has a start signal, and if so, step (B) is performed, and if not, step (C) is performed. In this way, to determine whether the engine is successfully started, it is determined that the engine is in a flameout state or a startup state.

When the engine is in the flameout state, (B) the injection computer has no output fuel signal, triggering the activation of the large lamp energy saving switch 21 and the safety light warning switch 22. At this time, the fuel signal between the fuel switch 41 and the fuel pump 4 cannot be detected, so the engine is not activated. According to the design of the present invention, the headlight energy-saving switch 21 and the safety light warning switch 22 should be triggered to save power and rear of the battery. The action of warning. In this embodiment, the triggering of the headlight energy-saving switch 21 means that the headlight is turned off, and the triggering of the start-up safety light warning opening relationship means that the safety light is turned on.

In contrast, when the engine is in the startup state, (C) the jet computer starts the fuel system and performs step (D). At this point, if the engine is to continue to operate, it is necessary to start the fuel system synchronously as the power supply for the engine combustion stroke.

When the injection computer starts the fuel system, the (D) injection computer outputs a fuel signal, triggers the shutdown of the headlight energy-saving switch 21 and the safety light warning switch 22, and performs step (E). At this time, the fuel signal outputted by the injection computer between the fuel switch 41 and the fuel pump 4 can be detected, so the engine has been started, and the headlight energy-saving switch 21 and the safety light warning switch 22 should be triggered to be turned off, so that the lamp system can be Maintain the working status during normal driving. In this embodiment, the triggering to turn off the headlight energy-saving switch 21 means that the headlight is turned on, and the triggering of the turn-off safety light warning open relationship means that the safety light is turned off.

After the step (D) triggers the closing of the safety light warning switch 22, the method further includes a step (D1) of determining whether the vehicle line is activated. If yes, the safety light 13 is turned on. If not, the safety light 13 is turned off. In this embodiment, the safety light 13 is a brake light. Therefore, when the engine is started, the control unit 3 detects whether the brake line is activated, and simultaneously turns the safety light 13 on or off. The car produces a warning.

On the other hand, after the injection computer outputs the fuel signal, it continues (E) to determine whether the engine is stopped. If not, the step (D) is repeated, and if so, the step (F) is executed. In this way, it is confirmed whether the engine is continuously operated or the engine is idling or shutting down, and it is used as a reference for whether to change the state of the lamp system.

Finally, (F) determines whether the key switch is turned off, and if so, the engine is stopped and stopped, and the control flow is terminated. If not, the engine idle stop is temporarily stopped, and the process returns to step (A). Therefore, the last step (F) can be used to determine the cause of the engine termination. If the manual is closed manually, the loop is jumped out to end the current control method; if the engine speed or the vehicle speed is zero for a period of time, the idle speed is entered. In the flameout phase, you should enter step (A) again, and before the engine restarts, go to step (B) to spray the computer without output fuel signal, trigger the start of the big lamp energy-saving switch 21 and a safety light warning switch 22, the lamp system Maintain energy saving and warning status until the engine starts up again.
