Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by those skilled in the art without making any inventive effort based on the embodiments of the present invention are within the scope of protection of the present invention.
In a first aspect, an embodiment of the present invention provides a method for determining an installation position of a safety control device.
Referring to fig. 1, the method provided by the embodiment of the present invention may include the following steps S110 to S130:
s110, acquiring preset size requirement information meeting the safety control requirement of the safety control device;
the safety control device comprises at least two shielding sensors, at least two reflecting plates corresponding to the at least two shielding sensors one by one and at least one safety light curtain device, and the preset size requirement information comprises light rays sent by the shielding sensors, a light curtain net formed by the safety light curtain device and a spacing requirement between at least two intersection points formed by edges of a conveying belt in the conveying system.
In practice, the method may be executed by any device having computing capability, for example, a user inputs the preset size requirement information and the field layout size information on a man-machine interaction interface of the device, and the device may output the value ranges of the mounting positions of the two shielding sensors and the two reflecting plates after a certain operation.
For example, referring to fig. 2, a light emitter is installed at one side of the conveyor belt, and a light receiver is installed at the other side, thereby forming a light curtain net. And two shielding sensors are arranged on one side of the conveyor belt, and two reflecting plates are arranged on the other side of the conveyor belt, wherein the two shielding sensors and the two reflecting plates are in one-to-one correspondence. Through the cooperation of the safety light curtain, the shielding sensor and the reflecting plate, the safety alarm can not be triggered when materials pass through the conveyor belt, and the safety alarm can be triggered when personnel pass through the conveyor belt, so that the safety control is realized.
Wherein, a shielding sensor and a reflector are a set of, and the light that this shielding sensor sent is got back after reaching corresponding reflector. The safety light curtain apparatus includes a light emitter which may be installed at one side of the conveyor belt and a light receiver which may be installed at the other side of the conveyor belt such that a light curtain net formed between the light emitter and the light receiver is perpendicular to a moving direction of the conveyor belt.
It will be appreciated that the light from the shielded sensor will have an intersection with the light curtain net. If the at least two shielding sensors and the at least two reflecting plates are crossed and correspond to each other, the light rays emitted by the at least two shielding sensors can also have intersection points. The light emitted by at least two shielding sensors, the light curtain net and the edge of the conveyor belt can also have intersection points. In order for the installation of the installation control device to meet the safety control requirements, the spacing between the points of intersection, i.e. the preset dimensional requirement information above, is required.
In one embodiment, the installation control device may adopt the following layout manner:
referring specifically to fig. 2, the at least two shielding sensors include a first shielding sensor 11 and a second shielding sensor 21, the first shielding sensor 11 and the second shielding sensor 21 are located on one side of a conveyor belt in the conveying system, a reflector plate 12 corresponding to the first shielding sensor 11 and a reflector plate 22 corresponding to the second shielding sensor 21 are located on the other side of the conveyor belt in the conveying system, the first shielding sensor 11 is located in a first area, and the second shielding sensor 21 is located in a second area; the first light ray and the second light ray intersect on the central line of the conveyor belt 4 along the movement direction, the first light ray and the second light ray intersect with the light curtain net, the first light ray is a light ray between the first shielding sensor 11 and the corresponding reflector 12, and the second light ray is a light ray between the second shielding sensor 21 and the corresponding reflector 22.
That is, two shielding sensors are employed in the installation control device, the two shielding sensors being provided on one side of the conveyor belt 4, and two reflecting plates being provided on the other side of the conveyor belt 4. Furthermore, the two shielding sensors are located in different areas, and the two reflectors are also located in different areas, since the first light emitted by the first shielding sensor 11 and the second light emitted by the second shielding sensor 21 are on the center line of the conveyor belt. The first light ray and the second light ray also intersect the light curtain net.
In an actual working scenario, the first area may be a safety area, the second area may be a dangerous area, the so-called safety area is an area where a worker can move, and since the main operation devices are all located in the dangerous area, in order to avoid personal injury to the worker during the processing, the worker should be prevented from entering the dangerous area to move.
Of course, other arrangements are possible than the above, for example, four shielding sensors and 4 reflectors, and for example, the light emitted from each shielding sensor is parallel. While the embodiments of the present invention are hereinafter mainly directed to the installation control device shown in fig. 2 for determining the installation position.
For the installation control device of the layout shown in fig. 2, the preset size requirement information may include a value range requirement of the first pitch, a value range requirement of the second pitch, and a value requirement of the third pitch; the first interval is an interval between a first intersection point and a second intersection point, the second interval is an interval between the first intersection point and a third intersection point, and the third interval is an interval between the intersection points of the first light ray and the second light ray and the light curtain net respectively; the first intersection point is an intersection point of the first light ray and the first conveyor belt edge 41, the second intersection point is an intersection point of the second light ray and the first conveyor belt edge 41, and the third intersection point is an intersection point of the light curtain net and the first conveyor belt edge 41; the first conveyor belt edge 41 is the edge on the same side as the shielding sensor of the two side edges of the conveyor belt.
That is, for the layout shown in fig. 2, the preset size requirements mainly include two value range requirements and one value requirement, the two value range requirements are the value range requirement of the first pitch and the value range requirement of the second pitch, and the one value requirement is the value requirement of the third pitch. The first intersection point is point R, the second intersection point is point T, and the third intersection point is point S, so that the first pitch refers to the physical length of line segment RT in fig. 2 in real space, the second pitch refers to the physical length of line segment RS in fig. 2 in real space, and the third pitch refers to the physical length of line segment PQ in fig. 2 in real space. The first conveyor edge 41 in fig. 2 is the edge where the line segment RT is located, and the second conveyor edge 42 is the edge where the line segment HJ is located.
For example, in practice, the first pitch has a value of [400,500], the second pitch has a value of [100,120], and the third pitch has a value of 500. The unit of the above value is millimeter.
The specific working principle of the safety control device shown in fig. 2 is as follows:
(1) If the light screen is broken first, it is stated that a person enters the hazard zone from the safety zone along the centre line of the conveyor belt, because the width of the person is less than 500 mm, the light screen is broken first. In order to avoid injury to personnel caused by operation equipment in the dangerous area, the safety light curtain equipment can give an alarm, and the safety loop can control the operation equipment in the dangerous area to stop.
(2) If the light rays emitted by the two shielding sensors are interrupted firstly and simultaneously, the situation that the materials 5 are from the safety area to the dangerous area or from the dangerous area to the safety area along the central line of the conveyor belt is described, because the width of the materials 5 is generally larger than 500 mm, the two shielding sensors and the safety light curtain device can not give an alarm under the condition, and then the operation device in the dangerous area normally operates.
(3) If a person walks along the edge of the conveyor belt, the light emitted by one of the shielding sensors is interrupted, so that an alarm is triggered if the light emitted by one of the shielding sensors is interrupted, and the safety circuit controls the operating devices in the danger area to stop.
The safety loop is connected with the shielding sensor and the safety light curtain device, and when the shielding sensor and the safety light curtain device give an alarm, the operation device in the dangerous area is controlled to stop running.
The third distance is used to distinguish the width of the person from the width of the material 5, and thus to distinguish the person from the material 5. The first interval and the second interval can indirectly reflect the information such as the width of the conveyor belt, the distance between the shielding sensor and the safety light curtain device and the like. The information has certain requirements, and the safety control device can play an optimal safety control function only if the requirements are met.
S120, acquiring site layout size information after the safety light curtain equipment is installed;
during actual installation, the safety light curtain device can be installed first, after the safety light curtain device is installed, the safety light curtain device is taken as a reference, the installation positions of the shielding sensor and the reflecting plate are determined, and the installation is performed after the installation positions are determined.
Wherein the required site layout size information is different for safety control devices of different layouts. For the layout of the safety control device shown in fig. 2, the field layout size information may include the width of the conveyor belt, the distance between the first device 31 on the same side as the shielding sensor in the safety light curtain apparatus and the first conveyor belt edge 41, and the distance between the second device 32 on the same side as the reflector plate in the safety light curtain apparatus and the second conveyor belt edge 42; the first device 31 is one of a light emitter and a light receiver, and the second device 32 is the other of the light emitter and the light receiver; the second conveyor belt edge 42 is the edge on the same side as the reflector plate of the two side edges of the conveyor belt.
That is, the width of the conveyor belt, i.e., the length of the segment SI in fig. 2 in real physical space. The distance between the first device 31 on the same side of the screen sensor in the safety light curtain apparatus and the first conveyor edge 41 is in fact the length of the line segment ES in fig. 2 in real physical space. The spacing between the second device 32 and the second conveyor edge 42 on the same side of the reflector in the safety light curtain apparatus is effectively the length of the line segment IF in fig. 2 in real physical space.
It will be appreciated that the field layout size information may be obtained by measuring after the installation of the safety light curtain device, and then input into a device having computing power, such as a computer.
S130, determining the value ranges of the installation positions of the at least two shielding sensors and the at least two reflecting plates according to the preset size requirement information and the on-site layout size information.
It can be understood that after the computer device obtains the preset size requirement information and the field layout size information, the value ranges of the installation positions of the two shielding sensors and the two reflecting plates can be determined according to the equal ratio relation between the geometric line segments in fig. 2.
In fig. 2, the range of the installation position of the first shielding sensor 11 is actually the range of the length of the line segment AE in the real physical space, the range of the installation position of the second shielding sensor 21 is actually the range of the length of the line segment ED in the real physical space, the range of the installation position of the reflector 12 corresponding to the first shielding sensor 11 is the length of the line segment CF in the real physical space, and the range of the installation position of the reflector 22 corresponding to the second shielding sensor 21 is the length of the line segment BF in the real physical space. It can be seen that the above-mentioned value ranges are all referenced to the safety light curtain device.
The following determination is made for the above four value ranges in the following manner:
(1) The range of values of the installation position of the first shielded sensor 11, that is, the range of values of the length of the line segment AE in the real physical space:
in step S130, determining the value ranges of the installation positions of the at least two shielding sensors and the at least two reflecting plates, referring to fig. 3, may specifically include S131 and S132:
s131, determining a first expression corresponding to the fourth interval according to the proportional relation between the geometric line segments; wherein the first expression includes a width of the conveyor belt, a spacing between the first device 31 and the first conveyor belt edge 41, the third spacing, and the second spacing; the fourth pitch is a distance between the first shield sensor 11 and the first device 31, that is, a length of a line segment AE in a real physical space.
That is, the physical lengths of the line segments SI, ES, PQ, RS in fig. 2, respectively, in the real space are included in the first expression.
Referring to FIG. 2, the length of the segment PE isThe length of the line segment PS is +.>The length of the line segment RS is the second interval, L is used 2 And (3) representing. W is the width of the conveyor belt, i.e. the length of the line segment SI in real physical space. L (L) 3 The third pitch, i.e., the length of the segment PQ in real physical space. L (L) 22 The distance between the first device 31 and the first conveyor edge 41, i.e. the length of the line segment ES in real physical space. L (L) 2 The second pitch, i.e. the length of the line segment RS in real physical space.
The geometric line segments have the following equal proportion relation:
the first expression can be obtained based on the above equal-proportion relation as follows:
wherein L is 4 The fourth distance, i.e., the length of the line segment AE in real physical space.
S132, determining the value range of the fourth interval according to the value range requirement of the second interval, the value requirement of the third interval, the width of the conveyor belt and the interval between the first device 31 and the first conveyor belt edge 41 in the first expression.
It will be appreciated that in the first expression, the second interval is a range, so that after the remaining parameters are brought into the first expression, the value range of the fourth interval can be obtained according to the value range requirement of the second interval.
For example, the second pitch has a value range of [100, 120], so the fourth pitch has a value range as follows:
it can be seen that the value range of the length of the line segment AE in the real physical space can be obtained in the above manner, so that the value range of the installation position of the first shielding sensor 11 is known.
(2) The range of the installation position of the second shielded sensor 21, that is, the range of the length of the line segment DE in fig. 2 in the real physical space:
in S130, determining the range of values of the installation positions of the at least two shielding sensors and the at least two reflectors, referring to fig. 4, may include the following steps S133 and S134:
s133, determining a second expression corresponding to the fifth interval according to the proportional relation between the geometric line segments; wherein the second expression includes a width of the conveyor belt, a spacing between the first device 31 and the first conveyor belt edge 41, the third spacing, the first spacing, and the second spacing; the fifth pitch is a distance between the second shield sensor 21 and the first device 31;
That is, the line segment SI, the line segment ES, the line segment PQ, the line segment RT, and the line segment RS in fig. 2 are included in the second expression.
Referring to FIG. 2, the line segment QE may be expressed asSegment ST can be expressed as L 1 -L 2 The segment QS can be expressed as +.>W is the width of the conveyor beltI.e. the length of the line segment SI in real physical space. L (L) 22 The distance between the first device 31 and the first conveyor edge 41, i.e. the length of the line segment ES in real physical space. L (L) 3 The third pitch, i.e., the length of the segment PQ in real physical space. L (L) 2 The second pitch, i.e. the length of the line segment RS in real physical space. L (L) 1 The first pitch, i.e. the length of the line segment RT in real physical space.
The geometric line segments have the following equal proportion relation:
the second expression can be obtained according to the above equal proportion relation:
wherein L is 5 The fifth interval is the length of the line segment DE in the real physical space; w is the width of the conveyor belt, L 3 For the third interval, L 22 L is the distance between the first device 31 and the first conveyor edge 41 2 For the second interval, L 1 Is the first pitch.
S134, determining the value range of the fifth interval according to the value range requirement of the first interval, the value range requirement of the second interval, the value requirement of the third interval, the width of the conveyor belt and the interval between the first device 31 and the first conveyor belt edge 41 in the second expression.
It can be understood that, in the second expression, the first pitch and the second pitch are a range, and since the difference between the first pitch and the second pitch is the length of the line segment ST, the value range requirement of the first pitch and the second pitch can be converted into the value range requirement of the low line segment ST, and then the value range of the fifth pitch can be determined according to the value range requirement of the line segment ST.
For example, the first pitch has a value range of [400, 500], the second pitch has a value range of [100,120], and the line segment ST has a value range of [280, 400], and the fifth pitch has a value range of:
it can be seen that the range of the length of the line segment DE in the real physical space can be obtained in the above manner, so that the range of the installation position of the second shielding sensor 21 is known.
(3) The range of the installation position of the reflector corresponding to the second shielding sensor 21, that is, the length of the line segment BF in the real physical space:
in S130, determining the range of values of the installation positions of the at least two shielding sensors and the at least two reflectors, referring to fig. 5, may include the following steps S135 and S136:
s135, determining a third expression corresponding to the sixth interval according to the proportional relation between the geometric line segments; wherein the first expression includes a width of the conveyor belt, a spacing between the second device 32 and the second conveyor belt edge 42, the third spacing, and the second spacing; the sixth distance is a distance between the reflector corresponding to the second shielding sensor 21 and the second device 32;
That is, the third expression includes a segment SI, a segment IF, a segment PQ, and a segment RS.
Wherein the line segment QF can be expressed asSegment QI can be denoted as +.>The segment HI and the length are equal to the length of segment RS, so segment HI is denoted as L 2 . W is the width of the conveyor belt, i.e. the line segment SI is in real physical spaceIs a length of (a) a (b). L (L) 3 The third pitch, i.e., the length of the segment PQ in real physical space. L (L) 2 The second pitch, i.e. the length of the line segment RS in real physical space. L (L) 33 The distance between the second device 32 and the second conveyor edge 42, i.e. the length of the line segment IF in real physical space.
The geometric line segments have the following equal proportion relation:
the third expression can be deduced from the above-mentioned equal-proportion relationship as:
wherein L is 6 For the sixth pitch, the length of the line segment BF in real physical space; w is the width of the conveyor belt, L 3 For the third interval, L 33 L is the distance between the second device 32 and the second conveyor edge 42 2 And the second interval is the second interval.
S136, determining the value range of the sixth interval according to the value range requirement of the second interval, the value requirement of the third interval, the width of the conveyor belt and the interval between the second device 32 and the edge 42 of the second conveyor belt in the first expression.
