Detailed Description
The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description herein is only intended to illustrate and explain embodiments of the present invention, and is not intended to limit embodiments of the present invention.
The mounting position of an arm support operation rollover warning lamp for prompting warning information of the existing engineering machinery is on a bracket or a rotary table of a vehicle body. Taking a pump truck as an example, as shown in fig. 1, a warning light of the pump truck is located at a front leg of a truck body. Or, as shown in fig. 2, the warning light of the pump truck is located at the rear support leg of the truck body, and in the running process of the pump truck, the driver needs to transfer the sight to the truck body of the pump truck to see the warning light. As shown in fig. 3, when the pump truck is rammed on the roof or in a foundation pit, the warning light may be in a blind area of the field of view of the mobile phone due to shielding, and the mobile phone cannot quickly and effectively view the warning light to obtain the operation safety indication information of the boom of the pump truck during operation, so that inconvenience is brought to the field operation of the mobile phone.
Based on this, the embodiment of the utility model provides an arm support operation safety indicating system installs in the delivery hose position of arm support cloth through indicating the light module for the cell phone can conveniently acquire arm support operation safety indicating information fast, and in addition, this system still indicates multiple pilot light according to the warning information suggestion of difference, provides more abundant arm support operation safety indicating information to the cell phone. The warning information prompted by the indicator light module can include a tipping risk and/or a movement limit, when the arm support moves to enable the engineering machinery to have the tipping risk, or the arm support moves to have the movement limit, for example, the arm support moves beyond a clockwise/anticlockwise maximum rotation angle, and the indicator light module warns the arm support to move to which kind of safety risk exists through specific indicator light to the mobile phone.
The boom operation safety indicating system comprises: and the indicator light module is arranged at the position of a conveying hose of arm support cloth of the engineering machinery and used for prompting the tipping risk and the motion limitation. Fig. 6 is a schematic view of the installation position of the indicator light module, and the components indicated by 1, 2 and 3 in fig. 6 constitute the indicator light module installed at the position of a conveying hose of arm support cloth. The indicator light module can give out light information in a certain direction to indicate the tipping risk and the movement limitation in the direction. For example, a robot located near the pump truck manually identifies the rollover risk and the motion limit of the pump truck, and controls an indicator light device (such as an indicator light) in an indicator light module to be turned on or off in the corresponding direction through a remote controller so as to indicate to an operator working near the end of the boom in which direction the pump truck has the rollover risk and the motion limit, so as to assist the operator in safe construction.
In order to more accurately acquire the tipping risk and the movement limit of the engineering machinery, the boom operation safety indicating system is preferably further provided with a module capable of automatically judging the tipping risk and the movement limit and controlling an indicating light module according to the tipping risk and the movement limit.
As shown in fig. 4, the boom operation safety indication system includes: the safety monitoring module is used for monitoring the mechanical safety state of the engineering machinery equipped with the arm support, and the mechanical safety state comprises equipment state parameters for judging the tipping risk and the motion limitation of the engineering machinery. For example, the mechanical safety state may be a gravity center position of the engineering machinery arm support at different positions, and the safety monitoring module may include a pressure sensor capable of sensing the gravity center position of the engineering machinery. In addition, the mechanical safety state may also be a rotation angle of the boom, in which case, preferably, the safety monitoring module may include: and the rotation angle detection sensor is used for detecting the rotation angle of the arm support. The rotation angle detection sensor can be a rotation limit sensor which detects the position state when the arm support rotates to the upper limit or the lower limit of the rotatable angle, and can also be a rotation encoder which can detect any rotation angle of the arm support.
The boom operation safety indicating system further comprises a control module used for determining the tipping risk and the movement limit according to the mechanical safety state and generating an indicating light control instruction.
The indicator light control command may not be limited to being generated by the control module, but may be given by other means, such as manual identification of the risk of tipping by a cell phone and movement limitation.
Fig. 5 is a simple control circuit of a pure hardware example of the indicator light module, wherein S _ D1 and S _ D2 are rotation limit switches of the arm in the D1 direction and D2 direction, respectively, to reach the limit positions. When the rotation limit sensor detects that the arm support reaches the limit position in the direction of D1 (or D2), the state of the normally closed contact of S _ D1 (or S _ D2) is changed from a normally closed state to opening, the rotation command signal of V _ D1 (or V _ D2) is switched, and the arm support stops responding to a control command given by a mechanical hand to continue rotating towards the limit position. Meanwhile, the normally open contact state of the S _ D1 (or S _ D2) is changed to be closed from the normally open state, the indicator lamp L _ D1 (or L _ D2) is driven to be lightened, the operation of prompting the movement towards the direction D1 (or D2) is forbidden, namely the manipulator controls the arm support to move towards the direction D1 (or D2) and cannot obtain the response of equipment, and the manipulator can obtain arm support operation safety indication information according to the indicator lamp L _ D1 (or L _ D2).
The arm support operation safety indicating system further comprises an indicating light module, wherein the indicating light module is installed at the position of the conveying hose of arm support material distribution and used for responding to the indicating light control instruction to prompt tipping risks and motion limitation.
As shown in fig. 6, the indicator light module includes: fastener 1, light support 2 and indicator light equipment 3. The fastener 1 of the indicator light module is arranged at the position of a conveying hose of the arm support cloth and used for fixing the light bracket, and the indicator light module can be arranged at a hose part (A1) of the conveying hose and can also be arranged on a hose connecting piece (A2) of the conveying hose. The fastening member 1 may have a plurality of connection methods, for example, a clamp connection, an adhesive connection, a magnetic connection, etc. when the magnetic connection is adopted, the fastening member 1 of the indicator light module is installed at a metal part of the conveying hose.
And the light bracket 2 is arranged on the fastener 1 and used for installing the indicator light equipment 3. The indicating light equipment 3 is a functional device of the scheme, is arranged on the light support 2 and is used for prompting safety indication information.
The arm support operation safety indicating system is displayed as indicating light with directivity, so that the accuracy of the direction corresponding to each indicating light device needs to be ensured, namely the accuracy of the direction of the light support and the fastener needs to be ensured, the requirement can be realized by adding a directional structure, the corresponding relation of the fastener and the conveying hose on the annular mounting position is indicated by arranging the directional structure on the fastener and/or the conveying hose, the mounting direction of the light support can be determined, and the mounting direction of the indicating light device is also determined. There are various implementations of the orientation structure, for example, a key (slot), an arrow, a positioning installation hole can be designed on the fastener, or the orientation structure can be the light bracket itself with direction indication, as shown in fig. 7, D3 is oriented in the forward direction in fig. 7, and based on this direction, D1 is in the left direction and D2 is in the right direction. It can be seen that the light bracket of fig. 7 has its own direction indicating function, so that the D3 faces forward (away from the center of the arm support turntable) when the fastener is installed, thus avoiding uncertainty of the upward position of the light bracket in the loop.
The indicator light equipment is a device capable of emitting warning light. In order to enable the mobile phone to fully acquire the safety indication information, the indicating light equipment can prompt different safety indication information in different warning modes. Preferably, the indicator light device may include: an indicator light and/or a projection light. The indication method may be that an indicator light in a certain direction is turned on to indicate the rollover risk and the movement restriction level of the operation in the certain direction and/or the safety operation indication, or a projection light in a certain direction is turned on to indicate the rollover risk and the movement restriction level of the operation in the certain direction and/or the safety operation indication.
Of course, the indicator light module for indicating the risk of rollover and the motion limitation may be replaced by a voice system capable of indicating the safety indication information, and the installation position of the sounding device may refer to the installation position of the indicator light equipment.
The motion direction of the arm support can be divided into four directions of anticlockwise rotation, clockwise rotation, outward expansion and inward retraction. Because the gravity center position of the engineering machinery is changed inwards when the arm support is retracted inwards, the tipping risk and the movement limitation do not exist, and the tipping risk and the movement limitation are prompted in other three directions. Preferably, at least one of the indicator lights is mounted in at least one direction of the light bracket. Preferably, one indicator light device is respectively installed in the left direction (corresponding to the counterclockwise rotation motion), the right direction (corresponding to the clockwise rotation motion) and the forward direction (corresponding to the outward unfolding motion) of the light bracket, or only one indicator light device is respectively installed in the left direction and the right direction of the light bracket; the forward direction is a horizontal projection direction of a vector from the center of the boom turntable to the tail end of the boom, referring to fig. 11, a direction corresponding to a horizontal projection (shown by a dotted line in the figure) of a vector from the center of the boom turntable to the tail end of the boom is the forward direction, that is, a direction of the tail end of the boom departing from the center of the boom turntable, and fig. 11 is a schematic diagram illustrating that a lighting device (taking a projection lamp as an example) performs operation safety indication in the forward direction and the left direction. Fig. 7 shows a top view of the installation direction of the indicator light, as shown in fig. 7, D3 is the front direction, D1 is the left direction, D2 is the right direction, and most preferably, the indicator light is arranged in all three directions to fully indicate the tilting risk and the movement limit of the arm support to move in all directions.
The power supply of the light of the indicator light equipment is generally supplied by an external power supply, but can also be locally supplied by a device with electric power storage capacity (namely the power supply unit is integrated in the structural part of the indicator light equipment); when the power is supplied by an external power supply, indicating light equipment needs to lead out a power line; the light of the indicator light equipment is controlled by the control module, and the control signal can be accessed in a wired and wireless mode. Preferably, the control signal access mode is matched with the power supply mode, namely, the power supply is controlled by a wire when an external power line supplies power, and the power supply is controlled by a wireless signal when local power is supplied.
According to the arm support operation safety indicating system, the indicating light module is arranged at the position of the conveying hose of arm support cloth, so that convenience is brought to a manipulator to conveniently and quickly obtain arm support operation safety indicating information, and the operation safety is improved. In addition, through installing pilot lamp light equipment in a plurality of directions and according to the multidirectional pilot lamp light of the risk of tumbling and the motion restriction suggestion of different directions, provide more abundant cantilever crane operation safety instruction information for the cell-phone, can realize the function of guide cell-phone to carry out safe operation, avoid engineering machine to take place to tumble danger.
Based on the above-mentioned boom operation safety indication system, the present application also provides a boom operation safety indication method, which is implemented by a control module and provides richer safety indication information for a handset, as shown in fig. 8, the method includes S102-S106:
and S102, acquiring the mechanical safety state of the engineering machinery provided with the arm support.
The mechanical safety state is obtained by a safety monitoring module, and the mechanical safety state can be the gravity center position of the engineering machinery, the rotation angle of the arm support or other mechanical safety states which can be used for calculating the rollover risk and the motion limitation.
And S104, determining the rollover risk and the motion limit of the engineering machinery according to the mechanical safety state.
The control module may determine the rollover risk and the motion limit of the construction machine according to the machine safety state in various manners, for example, whether the rollover risk and the motion limit exist in the boom motion direction may be determined according to whether the gravity center position of the construction machine exceeds the support boundary, or whether the rollover risk and the motion limit exist according to whether the rotation angle of the boom of the construction machine exceeds the preset rotation angle range.
Since the boom may tilt when moving in three directions, it is preferred that the risk of tilting and the limitation of movement are determined based on the mechanical safety of the boom when moving in different directions.
In the first case, in a case where the acquired mechanical safety state is the position of the center of gravity of the construction machine, in particular, one of the methods of S102 and S104 preferably includes the following steps (1) to (3):
(1) acquiring the current gravity center position and the supporting boundary of the engineering machinery;
(2) determining new gravity center positions corresponding to the three directions of movement of the arm support, namely anticlockwise rotation, clockwise rotation and outward expansion respectively according to a safety gravity center deviation threshold value at the current gravity center position;
(3) determining that the direction corresponding to the new center of gravity position has rollover risk and motion limitation under the condition that the new center of gravity position exceeds the supporting boundary; determining that the new center of gravity position corresponds to a direction without risk of tipping and limitation of motion in the event that the new center of gravity position does not exceed the support boundary.
The above steps are explained by taking fig. 9 as an example:
(1) the control module acquires a current gravity center position and a support boundary of the engineering machine, the acquired current gravity center position takes 4 positions (an S point, a G point, a Q point and a P point) in fig. 9 as an example, and the support boundary is a quadrilateral outer frame.
(2) If the safe gravity center deviation threshold is dd, and the safe gravity center deviation threshold dd is used as the change amplitude of the gravity center change caused by the movement of the boom, when the current gravity center position is at the point G, G1 is a new gravity center position corresponding to the boom after anticlockwise rotation, G2 is a new gravity center position corresponding to the boom after clockwise rotation, G3 is a new gravity center position corresponding to the boom after outward unfolding, GG1 is GG2 and GG3 and dd, the dd value range is 0.3-1 meter, preferably dd is 0.4-0.5 meter, and the same applies to the point Q and the point S.
(3) For point G, G2 and G3 are outside the support boundary, so it is believed that a clockwise pivoting or outward deployment of the boom will cause the center of gravity of the device to move out of the support area (and thus cause a rollover), then the D2 and D3 directional indicator lights will light up and the D1 directional indicator light will not light up. As shown in fig. 9, abbreviated as [ D1 ═ 0 ], D2 ═ 1, and D3 ═ 1 ], the arm support operation that reminds the aircraft crew to turn clockwise or unfold outward may have tipping risk and motion limitation. If the control module of the work machine has limited the movement in both directions, the D2 and D3 directional indicator lights are used to indicate to the pilot that there is a current response limit for the pilot to both clockwise swing and flare operations.
Similarly, for the point P, only P1 is outside the support boundary, the indicator light device in the direction D1 lights up, which is abbreviated as [ D1 is 1, D2 is 0, and D3 is 0 ], and the arm support only has the motion limitation of counterclockwise rotation;
for the point Q, only Q3 is outside the supporting boundary, the indicator light equipment in the direction D3 is lighted up, which is abbreviated as [ D1 is 0, D2 is 0, and D3 is 1 ], so as to avoid the gravity center overflow caused by unfolding or bending over the flat arm frame;
for the point S, S1, S2, and S3 are all within the support boundary, and the indicator lights in three directions are turned off, which is abbreviated as [ D1 ═ 0, D2 ═ 0, and D3 ═ 0 ], indicating that the boom does not have a tipping risk and a motion limitation when moving in any direction.
In the second case, in the case that the obtained gravity center position is the rotation angle of the boom, the other method of S102 and S104 preferably includes the following steps (1) to (3):
(1) acquiring a current rotation angle, a lower rotation angle limit and an upper rotation angle limit of the arm support;
(2) determining new rotation angles corresponding to the movement of the arm support at the current rotation angle in the counterclockwise rotation direction and the clockwise rotation direction respectively according to the safety angle deviation threshold value by taking the clockwise direction as the increment direction;
(3) determining that the tilting risk and the movement limit exist in the movement direction corresponding to the new rotation angle under the condition that the new rotation angle is lower than the lower limit of the rotation angle or higher than the upper limit of the rotation angle; and under the condition that the new rotation angle is not lower than the lower limit of the rotation angle and not higher than the upper limit of the rotation angle, determining that the motion direction corresponding to the new rotation angle has no tipping risk and no motion limitation.
The arm support of the engineering machinery has the limitation of a rotation angle, and the operation area of the arm support is limited by limiting the rotation angle of the arm support so as to ensure the operation safety. In this embodiment, whether there is a rollover risk and a movement limitation is determined according to whether the rotation angle of the boom of the engineering machinery exceeds a preset rotation angle range, and the specific implementation manner of the steps (1) to (3) is as follows:
(1) acquiring the current rotation angle theta and the lower limit theta of the rotation angle of the arm support1And upper limit of rotation angle theta2。
(2) Setting the safety angle deviation threshold value as thetaErrAt a safety angle deviation threshold thetaErrAs the change amplitude of the rotation angle of the arm support movement, clockwise is taken as the increment direction, and the current rotation angle theta of the arm support is respectively calculated according to the safety angle deviation threshold value as thetaErrNew rotation angle theta + theta after clockwise rotationErrAnd the deviation threshold value of the current rotation angle theta of the arm support according to the safety angle is thetaErrNew rotation angle theta-theta after counterclockwise rotationErr。
(3) When theta + thetaErr>θ2When the arm support continues to rotate clockwise, the new rotation angle exceeds the upper limit of the rotation angle, and at the moment, the indicator light equipment in the direction D2 (clockwise rotation direction) is lightened; when theta-thetaErr<θ1When the boom continues to rotate counterclockwise, the new rotation angle is lower than the lower limit of the rotation angle, and at this time, the indicator light device in the direction D1 (counterclockwise rotation direction) is turned on. Therefore, the system can clearly remind the aircraft driver of the rotary operation in which direction the aircraft driver has risks, thereby avoiding equipment damage and property loss caused by misoperation.
And S106, generating an indicator light control instruction according to the tipping risk and the motion limit so as to control the indicator light equipment.
Corresponding to S104, when the tipping risk and the movement limit corresponding to the movement of the arm support to a certain direction exist, an indicator light control instruction is generated according to the tipping risk and the movement limit, and the indicator light equipment in the direction is controlled to send out safety indication information.
Preferably, the indicator light device includes: and an indicator light and/or a projection light, wherein the indicator light or the projection light in a certain direction is lighted up to indicate the rollover risk of the operation in the direction, the motion limit level and/or the safe operation indication.
Preferably, the different forms of warning signals prompt different safety indication information, including the following schemes:
a. the indicator light is normally on in a first color (such as red) to indicate that the direction corresponding to the indicator light has a first rollover risk and a movement restriction level, and the indicator light flashes in the first color (such as red) to indicate that the direction corresponding to the indicator light has the second rollover risk and the movement restriction level.
The first color is used as a warning color, and two different levels of tipping risk and motion limitation are prompted through two states of constant brightness and flickering. The first grade of tipping risk and the movement limit level are higher than the second grade of tipping risk and the movement limit level, so that when the two signals are seen, the mechanical staff needs to pay attention to carefully operating the arm support to move, and when the indicator light is normally on in the first color, the operation amplitude of the arm support is smaller and the movement speed is slower than when the indicator light is flickering in the first color.
b. The indicating lamp is normally on in a first color (such as red), the indicating lamp is prompted to have rollover risks and motion limitation in the direction corresponding to the indicating lamp and to be limited in motion, the manipulator controls the arm support to move towards the direction, and no equipment response can be obtained, the indicating lamp is normally on in a third color (such as green), the indicating lamp is prompted to be safe in the direction corresponding to the indicating lamp, and the manipulator controls the arm support to move towards the direction, and the equipment response can be obtained.
The first color is used as a warning color, the third color is used as a safety color, and whether rollover risks and movement limitation exist or not is prompted by lighting indicator lamps of different colors. When the tipping risk and the movement limitation exist in a certain direction, the movement of the direction is limited, and the arm support cannot continue to move even if the manipulator operates the arm support to move towards the direction. When the tipping risk and the movement limitation do not exist in a certain direction, the manipulator can normally control the arm support to move towards the direction.
c. Two indicator lights are normally on in a certain direction with a first color (such as red) to prompt that the directions corresponding to the two indicator lights have equal tipping risks and movement limitation levels, and only one indicator light is normally on in a certain direction with the first color (such as red) to prompt that the directions corresponding to the indicator lights have equal tipping risks and movement limitation levels.
The indicating light equipment can be installed in various modes, a plurality of indicating light equipment can be installed in each direction of the light support, the two different levels of tipping risk and motion limitation are prompted by lighting different numbers of indicating lamps, and the safety operation indication received by the mobile phone is the same as the scheme a.
d. The projection lamp is normally on in a first color (such as red) to indicate that a direction corresponding to the linear projection boundary projected by the projection lamp has a first rollover risk and a movement restriction level, and the projection lamp is normally on in a second color (such as yellow) to indicate that a direction corresponding to the linear projection boundary transmitted by the projection lamp has a second rollover risk and a movement restriction level.
The projection lamp is different from the indicating lamp in indicating mode. Taking fig. 10 as an example, the projection lamp in the direction D2 projects a line projection in the first color, indicating that the boom would be at risk of tipping and restricted from moving if it continued to rotate clockwise. Similarly, if the projection lamp in the direction D1 projects a line projection in the first color, it indicates that the boom may be tilted and restricted if it continues to rotate counterclockwise. Similarly, if the projection lamp in the direction D3 transmits a linear projection in the first color, it indicates that the boom will be at risk of tipping and restricted in movement if it continues to expand outward. Similarly, as shown in fig. 11, the projection lamps in the directions D1 and D3 project linear projections in the first color, which indicates that the arm support cannot continue to rotate counterclockwise and cannot continue to unfold outward, otherwise there is a risk of tipping and a limitation of movement.
The scheme d takes a projection lamp as an example, the projection lamp projects linear projection, the projection lamp in a certain direction is lightened, the tipping risk and the movement restriction grade and/or the safety operation indication of the operation in the direction are prompted, and the different grades of the tipping risk and the movement restriction are prompted by projecting different colors of projections.
Of course, the above solutions a-d are only exemplary solutions, and they may be replaced with each other or combined appropriately, so that the robot can accurately and sufficiently know the rollover risk and the movement limitation and/or the safe operation indication. In addition to the methods listed in the above schemes, other indication methods may be included, for example, the projection lamp represents the warning information in the first color, the projection lamp represents safety when the projection lamp is not on, the projection lamp represents danger when the projection lamp slowly flashes in the first color, the projection lamp rapidly represents the approach of danger when the projection lamp flashes in the first color, and the projection lamp represents danger when the projection lamp is normally on in the first color; for example, the indication sound system can be matched with the indication light module to realize the safety indication function together, when the rollover risk and the movement limitation exist in a certain direction, the indication light module prompts the warning information through the light signal, and the sound system prompts the warning information and/or the safety operation indication through the sound signal.
According to the boom operation safety indication method provided by the embodiment, the indication lighting equipment prompts various safety indication information according to different tipping risks and motion limits, and a manipulator can clearly know whether the tipping risks and the motion limits exist or not and the grades of the tipping risks and the motion limits exist when the boom moves in all directions, so that the boom is controlled to perform safety operation according to the safety indication information, and the tipping risks and the motion limits of engineering machinery are avoided.
