[0027]结合相关技术可知,起重机上一般设置有操作手柄200、动作开关300和发动机700。 [0027] The apparent binding related art, an operating handle 200 is generally disposed on the crane, operation switch 300 and the engine 700. 其中,操作手柄200—般布置在操纵室座椅两侧,通过操纵操作手柄200可以控制起重臂进行起吊等动作。 Wherein, as the operating handle 200- disposed on both sides of the seat actuating chamber, by operating the operating handle 200 can control the operation of the lifting arm lifting the like. 动作开关300—般布置在操纵室的操纵台上,通过操纵动作开关300可以控制工程机械进行一些辅助作业,比如副臂与主臂的连接等。 Operation switch 300 disposed in the manipulation stage as the control room can be controlled by manipulating the operation switch construction machine 300 some auxiliary working, such as the sub-arm is connected to the main arm and the like.

[0028]如图1所示,本实施例中,转速传感器400安装在该工程机械的发动机700上,用于获取发动机700的转速信号。 [0028] 1, in this embodiment, rotation speed sensor 400 is mounted on the construction machine engine 700, the engine speed signal for obtaining 700. 控制器100与转速传感器400相连接,用于接收发动机700的转速信号。 The controller 100 is connected with the speed sensor 400, an engine 700 for receiving the speed signal. 控制器100还与该工程机械的操作手柄200和动作开关300相连接,用于获取操作手柄200和动作开关300的操作信号;控制器100还用于根据转速信号、操作手柄信号和动作开关信号判断该工程机械是否满足发动机熄火条件,并在满足熄火条件时发出熄火信号。 The controller 100 is also connected with the construction machine operating handle 200 and the operation switch 300, the operation for acquiring the operation lever 200 and the operation of the switching signal 300; a controller 100 for further switching signal according to the rotational speed signal, and the operation of the operation lever signal Analyzing the construction machine engine stall condition is satisfied, and emits a signal flameout flameout condition is satisfied.

[0029]本实施例可以根据转速信号、操作手柄信号和动作开关信号判断起重机的工作情况,并在满足条件时自动控制发动机熄火,不仅节约了能源,而且也避免了非作业人员进入操纵室后可能产生的误动作,提高了安全性。 [0029] This embodiment can work according to the speed signal, an operation lever signal and the operation of the switching signal determining crane, and automatically controls the engine stall when the condition is satisfied, not only saves energy, but also to avoid the non-operating personnel to enter the cab malfunction may arise, improves security.

[0030]优选地,上述实施例中,熄火条件为:操作手柄信号、动作开关信号均为零,并且,转速信号不为零,并且,该状态持续了第一设定时间。 [0030] Preferably, the above-described embodiments, the flame conditions are: operation lever signal, the operation of the switching signal is zero, and the rotational speed signal is not zero, and the state continues for a first predetermined time.

[0031]通过以上分析容易理解,当操作手柄200和动作开关300同时处于复位状态,即不动作时,操作手柄200和动作开关300的操作信号同时为零;此时,操作人员没有操控起重机进行作业。 [0031] readily understood from the above analysis, when the operating handle 200 and the operation switch 300 while in the reset state, i.e., does not operate, the operating handle 200 and the operation switch 300 while the operation signal is zero; in this case, the crane operator does not manipulate operation. 若此时控制器100接收到发动机700转速不为零的信息,即发动机700处于工作状态;并且,转速不为零而操作手柄200和动作开关300同时为零的状态持续了第一设定时间,则控制器100会发出发动机熄火信号。 At this time, if the controller 100 receives the speed information of the engine 700 is not zero, i.e., the engine 700 is in operation; and, the rotational speed is not zero continues for a first predetermined time and the operating handle 200 and 300 while the operation of the switching state of zero , the controller 100 will issue an engine stall signal.

[0032]具体操作时,参见图2,可以通过熄火执行机构600控制发动机700熄火。 When the [0032] specific operation, refer to FIG. 2, it can turn off the engine stall control by the actuator 600 700. 具体地,熄火执行机构600—般布置在起重机上车操纵室电气控制箱内,控制器100与熄火执行机构600相连接,当熄火执行机构600接收到熄火信号时,其线圈接通,触点闭合,控制发动机700熄火。 Specifically, the actuator 600 like flame disposed on the lift truck cab electrical control box, the controller 100 and actuator 600 is connected to the flame, the flame when the actuator 600 receives the stall signal, which coil turns, contact closed, the engine control 700 flameout. 控制器100也可以向起重机的总线发送总线熄火数据包,发动机700接收到该总线熄火数据包后自动熄火。 Automatically turn off when the controller 100 may be the engine stall bus 700 receives the data packet to the bus transmits a bus packet flame crane. 此外,控制器100还可以发送熄火信号直接作用于发动机模块熄火输入点,以关闭发动机700 ο本领域人应当理解,控制器100控制发动机700熄火的实现方式多样,本发明对其不做任何限定。 Further, the controller 100 may also send a signal directly applied to the flame module input point of the engine stall, the engine 700 to close o the art shall be understood that the controller 100 controls the engine 700 to achieve diverse stall, the present invention is not limited in any of its .

[0033]具体操作时,可以根据实际情况确定第一设定时间,本发明对其不做限定。 [0033] Specific operation, a first set time may be determined according to the actual situation, the present invention is not limited thereof.

[0034]本实施例在起重机处于非作业状态并满足熄火条件时,控制发动机自动熄火,与现有技术相比,不仅节约了能源,同时,也减少了有害气体的排放和对环境的污染。 [0034] In the present embodiment, when the crane is in a working state and a non-flame conditions are satisfied, the control automatically turn off the engine, compared with the prior art, not only saves energy, but also reduces the harmful gas emissions and environmental pollution. 此外,也避免了非作业人员进入操纵室后可能产生的误动作,提高了安全性。 In addition, to avoid the erroneous operation of non-workers enter the cab may be generated, improving the security.

[0035]优选地,参见图3,还可以对本实施例作进一步改进,增设了输入输出单元500。 [0035] Preferably, referring to FIG. 3, the present embodiment can be further improved embodiment, the additional input-output unit 500. 控制器100还与输入输出单元500相连接,控制器100还用于在起重机满足熄火确认条件时向输入输出单元500发送熄火确认信号,并根据输入输出单元500的信息反馈情况确定是否发出熄火信号。 The controller 100 is also connected to the input 500 output unit, the controller 100 is further configured to turn off when the crane condition confirmation acknowledgment signal to a transmitter to turn off the input-output unit 500, and determines whether to issue a stall signal based on feedback information input-output unit 500 . 其中,熄火确认条件为:操作手柄信号和动作开关信号均为零,并且,转速信号不为零,以及该状态持续了第一设定时间。 Wherein the flame condition is confirmed: the operation lever signal is zero and the operation of the switching signal, and the rotational speed signal is not zero, and the state continues for a first predetermined time.

[0036]该实施例中,在起重机满足发动机熄火确认条件时,控制器100向输入输出单元500发送熄火确认信息,输入输出单元500接收并显示该熄火确认信息。 [0036] In this embodiment, a crane engine stall recognition conditions satisfied, the controller 100 transmits the input information to the acknowledgment flame output unit 500, an input output unit 500 receives and displays the confirmation message flameout. 具体操作时,输入输出单元500可以选择触摸屏或其他具有该功能的显示屏,一般布置在驾驶室中的仪表台上,以便于操作人员及时了解该信息并作出反馈。 Specific operation, the input-output unit 500 may select a touch screen, or other display with this function, the general arrangement of the dashboard in the cabin, so as to keep abreast of the operator and make feedback information. 控制器100再根据输入输出单元500的信息反馈情况确定该工程机械是否满足熄火条件,进而确定是否发出熄火信号。 The controller 100 then determines feedback information input-output unit 500 of the working machine meets the flameout condition, and thus determine whether a stall signal.

[0037]其中,控制器100发出熄火信号的条件为:在第二设定时间内,控制器100接收到输入输出单元500发送的确认熄火的反馈信息;或者,在大于第二设定时间时,控制器100未接收到输入输出单元500发送的任何反馈信息。 Alternatively, when greater than a second predetermined time; within the second set time, the controller 100 receives the feedback information confirmation unit transmits the input and output of the flame 500: [0037] wherein the conditions subject to the controller 100 to turn off signal , the controller 100 does not receive any feedback information transmitted from the input-output unit 500. 控制器100不发出熄火信号的条件为:在第二设定时间内,控制器100接收到输入输出单元500发送的不媳火的反馈信息。 100 stall condition is not sent to the controller signal: within the second set time, the controller 100 receives the feedback information is not fire-law input-output unit 500 of the transmission.

[0038]可以看出,在第二设定时间内,如果操作人员发出同意熄火的反馈信息,控制器100会发出熄火信号;如果操作人员发出不同意熄火的反馈信息,控制器100不会发出熄火信号。 [0038] As can be seen, within the second set time, if the operator agrees feedback information sent stall, the controller 100 will issue a stall signal; if the operator does not agree with flame emitted feedback information, the controller 100 does not issue flameout signal. 此时,控制器100会将之前的检测信息清零,重新检测满足发送熄火确认信息的条件。 In this case, before the controller 100 detects information will be cleared and re-transmission that satisfies a misfire condition confirmation information.

[0039]另外,如果操作人员在大于第二设定时间时,仍没有发出反馈信息,控制器100也会发出熄火信号。 [0039] Further, if the operator is greater than the second set time, the feedback information is still not issued, the controller will also issue a stall signal 100. 具体操作时,可以在控制器100内设置延时模块,控制器100在第二设定时间内未接收到输入输出单元的反馈信号时,控制器100再延时第三设定时间后发出熄火信号。 When the specific operation, delay module may be provided in the controller 100, the controller 100 does not receive a feedback signal input-output units within the second set time, the controller 100 then emits the third set time delay flameout signal.

[0040]具体操作时,可以根据实际情况确定第二设定时间和第三设定时间,本发明对其不做限定。 [0040] Specific operation, the second set time may be determined and the third set time according to the actual situation, the present invention is not limited thereof.

[0041] 具体操作时,也可以在控制器100和输入输出单元500之间设置开关,通过操作开关决定是否启用该输入输出单元500。 [0041] Specific operation, a switch may be provided between the controller 100 and the input output unit 500, by operating the switch decides whether the input-output unit 500 is enabled.

[0042]通过以上实施例,可以看出,本发明具有如下优势: [0042] By the above embodiments, it can be seen, the present invention has the following advantages:

[0043] I)本发明在起重机不作业时,自动关闭发动机,不仅减少了燃油消耗,节约了资源;同时,也减少了尾气排放和噪声污染,符合环保要求; [0043] I) of the present invention, when the crane is not operating, shut down the engine, not only reduces fuel consumption, saves resources; while also reducing exhaust emissions and noise pollution, environmental compliance;

[0044] 2)在操作人员长时间不在操纵室的情况下,避免了其他人员误操作造成的安全隐患; [0044] 2) In the case of prolonged absence operator control room, avoiding safety hazards caused by misuse of the others;

[0045] 3)该控制装置结构简单,易于实现。 Simple [0045] 3) The control unit structure, easy to implement.

[0059]如图所示,本实施例中的判断步骤进一步包括:第一子步骤,若发动机转速大于零,且操作手柄信号和动作开关信号均等于零,并且,该状态持续了第一设定时间,则向输入输出单元发送是否熄火的确认信号;第二子步骤,若在第二设定时间内,接收到输入输出单元反馈的确定熄火的信号,或者,在大于第二设定时间内,没有接收到输入输出单元反馈的任何信号,则判断该发动机满足熄火条件;若在第二设定时间内,接收到输入输出单元反馈的不熄火信号,则判断该发动机不满足熄火条件。 [0059] As shown, in the determining step further embodiment according to the present embodiment comprises: a first substep, when the engine speed is greater than zero, and the operation signal and the operation of the switching lever signals are equal to zero, and the state continues for a first set time, is sent to the input-output unit to confirm whether the misfire signal; a second sub-step, if the second set time, the received signal input and output of the feedback unit is extinguished, or greater than the second set time , does not receive any signal input-output unit feedback is judged that the engine stall condition satisfied; if the second set time, the received signal does not stall the feedback input-output unit, it is judged that the engine stall condition is not satisfied.

[0060]相对于第一实施例,本实施例增加了熄火条件确认步骤。 [0060] with respect to the first embodiment, the present embodiment increases the stall condition confirmation step. 具体地,在工程机械已满足:发动机转速大于零,且操作手柄信号和动作开关信号均等于零,以及,该状态持续了第一设定时间时,为安全起见,还要向输入输出单元发送熄火确认信息。 In particular, in the construction machine has been met: the engine speed is greater than zero, and the operation signal and the operation of the switching lever signals are equal to zero, and the state continues for a first predetermined time, for safety reasons, but also sent to the input-output unit flameout confirmation. 并根据输入输出单元的信息反馈情况确认是否熄火。 The information and confirms whether flameout feedback input-output unit. 本实施例的其他部分与第一实施例相同,兹不赘述。 Other parts of this embodiment is the same as the first embodiment, it is hereby not described herein.

[0061 ]下面结合图5对本实施例作进一步说明: [0061] below with reference to FIG. 5 of the present embodiment will be further described:

[0062]当控制器检测到发动机转速不为零,并且,操作手柄和动作开关均无操作信号,则控制器开始计时。 [0062] When the controller detects that the engine speed is not zero, and the operating handle operation and no operation of the switching signal, the controller starts. 若计时过程中发动机转速发生变化,或检测到操作手柄或动作开关的动作信号,则计时归零。 If the engine speed changes during counting, or detection of an operation signal of the operating handle or the operation switch, the time to zero. 若计时过程没有中断,当累计计时时间达到第一设定值时,控制器会控制操纵室的输入输出单元显示“熄火提示界面”,此时操作人员若不在操纵室,当该显示达到第二设定时间,而控制器没有接收到任何反馈信息时,控制器会自动控制发动机熄火。 If no timer interruption process, when the total time period reaches the first set value, the controller controls the input-output unit control room display "flameout prompt interface", then if the operator at the control room, when the display reaches the second when setting the time, and the controller does not receive any feedback information, the controller automatically controls the engine stall. 若此时操作人员在操纵室内,并且,操作人员在第二设定时间内通过显示屏选择熄灭发动机,则控制器控制发动机熄火;若操作人员在第二设定时间内通过显示屏选择不熄灭发动机时,控制器不控制发动机熄火,并将累计时间清零,重新检测熄火条件。 At this time, if the operator in the control room, and, in the operator selected the second set time the engine is off, the engine stall control by the display controller; if the operator selected through the display in the second set time is not extinguished the engine, the controller does not control the engine stall, and the accumulation time is cleared, the stall condition is detected again.

[0063] 综上可知,该方法不仅可以节省不必要的燃油消耗,节约资源,而且,还可以减少有害气体的排放和对环境的噪声污染。 [0063] To sum up, this method can not only save unnecessary fuel consumption, conservation of resources, but can also reduce emissions of harmful gases and noise pollution to the environment. 另外,该方法不仅适用于工程机械,也适用于具有间歇性工作特点的其他械设备,适用范围广。 In addition, this method is not only applicable to mechanical engineering, but also for other mechanical devices with intermittent work features a wide range of applications.

[0064]由于该控制方法与上述控制装置原理相似,所以相关之处可以相互参照。 [0064] Since the control method is similar to the above-described control principle of the device, it may be relevant, with reference to each other.
