Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of an apparatus control method according to the present invention, in this embodiment, the apparatus control method includes the following steps:
step S10: acquiring operation information detected by an operation induction device;
in this embodiment, the apparatus control method is applied to an electronic apparatus provided with a light curtain, where the light curtain is a safety protection device manufactured based on a photoelectric sensing principle, and is used to ensure personal safety of an operator and operation safety of the apparatus during operation of the apparatus, to avoid potential safety hazards when an operator (not necessarily a whole human body, but a part of the body, such as an arm or a finger, etc.) of the apparatus appears in an unsafe region, and to avoid apparatus faults and the like caused when other objects except a tool and a human body appear in the unsafe region, and the electronic apparatus may be specifically a stamping machine, a shearing machine, a metal cutting machine, an automatic assembly machine, an automatic welding machine, a mechanical transfer machine, and the like.
Before equipment operation, if want to get rid of the potential safety hazard through the light curtain, at first need confirm the light curtain and be in normal condition, because get the frock in-process, the light curtain can be sheltered from, therefore can get the in-process light curtain of getting the frock through the detection and shelter from the state and confirm whether the light curtain is in normal condition, and will detect the sheltering from the state of getting the in-process light curtain of getting the frock, will detect whether the operation of getting the frock exists earlier. In this embodiment, an operation sensing device is further disposed on the device, and may include a photoelectric sensor, an infrared sensor, a displacement sensor, and the like, for detecting the taking and placing operations of the tool, so as to detect whether the light curtain is normal or not in the process of taking and placing the tool. The operation sensing device can be installed at a position frequently operated by an operator according to the placing rule of the tool, the light curtain is also installed at the position frequently operated by the operator, the position of the operation sensing device is higher than the installation position of the light curtain and at least higher than the installation position of the infrared correlation tube at the top of the light curtain, and the installation position of the light curtain is higher than the height of the placed tool, namely the installation position of the infrared correlation tube at the bottom of the light curtain is at least higher than the height of the tool when the tool is completely placed into the equipment; the position frequently operated by the operator may be a position where a certain area of the apparatus is located when a certain part of the operator's body (such as an arm) is frequently present in the area; the operator may be a person or a robot or other automated device for picking and placing the tool.
On the basis, according to the actual application requirements, the light curtain and the operation sensing device can be one or a plurality of light curtains, for example, in order to save the manufacturing cost of the equipment, one light curtain and one operation sensing device can be arranged at the position frequently operated by an operator, the operation information of the tool is detected and taken by one operation sensing device, and whether the operator withdraws from a safe area and/or whether other objects except the tool exist in the detection area of the light curtain is determined by one light curtain; in order to improve the detection effect and the accuracy of the detection result, a plurality of light curtains and a plurality of sensing devices may be provided, for example, if the operator puts the tool into two hands, the corresponding positions frequently operated by the operator include at least two positions, and at this time, the light curtains and the sensing devices may be respectively installed at the two positions, so as to improve the accuracy of the operation information detection and the safety of the equipment operation. Of course, the positions and numbers of the light curtain and the operation sensing device can be the same or different, for example, when there are two positions (such as left hand and right hand) which are frequently operated by an operator, the operation sensing device can be installed on the left side, and the light curtain can be installed on the right side; or the operation induction device can be arranged on the left side, and the light curtains can be arranged on the left side and the right side simultaneously; it is also possible to install the operation sensing devices on both the left and right sides and the light curtain on the right side.
After the installation position and the number of the operation sensing devices are determined, the operation sensing devices can be used for detecting the operation information of the pick-and-place tool, so that a controller of the equipment can obtain the operation information detected by the operation sensing devices, the operation information can be specifically determined according to the distance information, the displacement information, the ambient light information and the like detected by the operation sensing devices, and certainly, the operation information can also be determined by combining the distance information, the displacement information, the ambient light information and the like.
Step S20: if the acquired operation information is the operation information of the tool and the light curtain is shielded before the tool is completely placed into the equipment, detecting whether the light curtain is shielded again when the tool is completely placed into the equipment;
after the operation information detected by the operation sensing device is acquired, the acquired operation information may be the operation information of the tool which is put in or taken out. In order to confirm whether the light curtain is in a normal state, when the acquired operation information is the operation information of the tool, firstly, the shielding state of the light curtain in the process of putting the tool needs to be acquired, and whether the light curtain can effectively eliminate the potential safety hazard of a dangerous area is confirmed according to the shielding state. The process of putting the tool into the equipment comprises the process from the time when the sensing device is operated to detect the tool to the time when the tool is completely put into the equipment.
Because the light curtain is installed in the position that the operator often operated, so get the in-process of putting the frock, the light curtain can be sheltered from. Therefore, if the light curtain is not shielded in the process of putting the tool into the tool, the light curtain is abnormal. When the light curtain is abnormal, the reason of the abnormal light curtain needs to be determined (for example, the infrared receiving tube or the transmitting tube is damaged or dust is accumulated), and corresponding processing is performed according to the determined reason (for example, prompt information is output to inform an operator of the reason of the abnormal light curtain and a solution which can be used for reference), so that the problem of the abnormal light curtain can be solved in time. After the fault is eliminated, whether other objects and human bodies except for the tool exist in a dangerous area of the equipment or not can be further detected through the light curtain, so that the normal operation of the equipment is ensured, and potential safety hazards do not exist; if the light curtain is shielded in the process of putting the tool into the tool, the light curtain can normally detect the shielding object and is in a normal state. At this moment, whether there is the potential safety hazard after the equipment is put into completely to accessible light curtain further detection frock. The light curtain is not always in a shielding state in the process of putting the tool in, and the light curtain is not always in the shielding state particularly depending on the distance between the light curtain and the position where the tool needs to be put in and the size of the tool, when the distance is far larger than the size of the tool, the light curtain possibly exists in an unshielded state before the tool is not completely put in the equipment, whether the light curtain is shielded or not can be judged according to the receiving state of each infrared receiving tube in a receiver of the light curtain or whether the light curtain is shielded according to the shielding time of the light curtain, and the shielding time of the light curtain can be determined according to the size of the tool, the speed of putting the tool and the like. Such as: when the distance between the light curtain and the position where the tool needs to be placed exceeds the height of the tool, if the light curtain is detected to be shielded in a first time period and is not shielded in a second time period after the first time period, the light curtain is considered to be shielded, namely the light curtain is in a normal state; otherwise, the light curtain is not blocked, and the light curtain is in an abnormal state; or, when the time that the light curtain is sheltered from is the same as the preset time corresponding to the tool, the light curtain is considered to be in a normal state.
After the light curtain is determined to be in a normal state, the installation position of the light curtain is higher than the height of the tool after the equipment is completely placed, and when the size of the tool needing to be placed changes or the position of the tool needing to be placed changes, the installation position of the light curtain can be manually or automatically adjusted according to the height of the tool after the equipment is completely placed, so that the light curtain is in an unshielded state when the equipment is completely placed in the equipment. Therefore, when the tool is completely put into the equipment, whether the light curtain is shielded or not can be detected again to confirm whether the dangerous area has potential safety hazards or not. Specifically, when the tool is completely put into the equipment, whether infrared receiving tubes in a receiver of the light curtain receive infrared light is judged, and if the infrared receiving tubes in the receiver of the light curtain do not receive the infrared light, the light curtain is judged to be blocked when the tool is completely put into the equipment; if all infrared receiving tubes in the receiver of the light curtain receive infrared light, the light curtain is judged not to be shielded when the tool is completely put into the equipment.
Step S30: if the light curtain is not shielded when the tool is completely placed into the equipment, controlling the equipment to normally operate;
if when the frock is put into the equipment completely, the light curtain is not sheltered from, then it indicates that there is not the sheltering object in the detection area of light curtain, also does not have the potential safety hazard in equipment danger area, can direct control this moment equipment normal operating, and continue to acquire the operation information that operation induction system detected to when obtaining the operation information of putting into next frock, whether effective (being in normal condition) is confirmed through the state of sheltering from of detecting the light curtain before the frock puts into the equipment completely earlier, then after confirming that the light curtain is effective, when the frock puts into the equipment completely, detect the state of sheltering from of light curtain once more, so that according to shelter from the state and confirm whether there is object or human body beyond the frock, when guaranteeing to put into the frock each time, can both investigate the potential safety hazard according to the state of sheltering from of light curtain, prevent that the missed inspection from causing the incident.
Step S40: and if the light curtain is shielded when the tool is completely put into the equipment, controlling the equipment to stop running.
If the tool is completely put into the equipment, the light curtain is detected to be blocked, which indicates that a blocking object exists in the detection area of the light curtain, and the blocking object may be a certain part of the body of an operator or other tools (the put tool is not required to be put into the tool), or other objects mistakenly put into the equipment in the process of putting into the tool, and the like. When a blocking object exists in a detection area of the light curtain, if the equipment is controlled to normally operate, personal safety of an operator, operation safety of the equipment and the like may be threatened. And thus it is necessary to control the apparatus to stop operating. The dangerous area is an area determined based on the position frequently operated by the operator, if the body or other objects of the operator appear in the area, certain potential safety hazards exist, and other areas except the dangerous area where the position operated by the user is located can be sealed.
In this embodiment, by acquiring operation information detected by an operation sensing device, if the acquired operation information is operation information of a tool and a light curtain is detected to be blocked before the tool is completely placed in a device, whether the light curtain is blocked is detected again when the tool is completely placed in the device, and if the light curtain is not blocked when the tool is completely placed in the device, the device is controlled to normally operate, and the step of acquiring the operation information detected by the operation sensing device is executed; and if the light curtain is shielded when the tool is completely put into the equipment, controlling the equipment to stop running. Whether the light curtain is in a normal state or not is determined according to the shielding state of the light curtain in the process of putting the tool, and when the light curtain is in the normal state, whether other objects or human bodies except the tool exist in the dangerous area or not is confirmed according to the shielding state of the light curtain after the tool is completely put into the equipment, so that the effectiveness of light curtain detection can be ensured, the potential safety hazard of the dangerous area can be eliminated, and the operation and running safety of the equipment is improved.
Referring to fig. 3, fig. 3 is a flowchart of a second embodiment of the apparatus control method according to the present invention, which is proposed based on the first embodiment. In this embodiment, the device control method includes the steps of:
step S11: acquiring operation information detected by an operation sensing device and pressure information detected by a tool sensing device;
step S12: determining whether the tool is completely placed into the equipment or not according to the acquired pressure information;
step S13: if the acquired operation information is the operation information of the tool and the light curtain is shielded before the tool is completely placed into the equipment, detecting whether the light curtain is shielded again when the tool is completely placed into the equipment;
step S14: if the light curtain is not shielded when the tool is completely put into the equipment, controlling the equipment to normally operate, and executing the step of acquiring the operation information detected by the operation sensing device;
step S15: and if the light curtain is shielded when the tool is completely put into the equipment, controlling the equipment to stop running.
In this embodiment, the equipment is provided with a tool sensing device in addition to an operation sensing device, the tool sensing device is configured to detect pressure information when a tool is placed into the equipment, so as to determine status information of the tool according to the pressure information, and the status information may include: the tool is completely put into the equipment and the tool is not completely put into the equipment, the operation sensing device can be a pressure sensor, a torque sensor and the like, and the operation sensing device is arranged at a position where the tool needs to be put into.
In order to obtain the shielding state of the light curtain before the tool is completely placed into the equipment, whether the tool is completely placed into the equipment needs to be determined, so that the operation information detected by the operation sensing device is obtained, meanwhile, the pressure information of the tool detected by the tool sensing device is also obtained, whether the tool is completely placed into the equipment is determined according to the obtained pressure information, and the pressure information at least comprises the detected pressure value and the corresponding detection time. If the pressure value is kept unchanged within the preset time after the tool sensing device detects the pressure and the pressure value changes for a certain time, the fact that the tool is placed at the position, required to be placed in, of the tool on the equipment is indicated, no external force except the supporting force of the position, required to be placed in, of the tool on the equipment can cause the pressure to change, namely, no acting force exists between an operator and the tool, and the fact that the tool is completely placed in the equipment is determined; however, if the tool sensing device detects pressure and the pressure is continuously changed (the pressure information is considered to be unchanged only when the pressure stabilization time reaches the preset time), it is determined that the operator is not completely separated from the tool in the process of placing the tool in the position, required to be placed, of the equipment, and at this time, it is determined that the tool is not completely placed in the equipment.
In an embodiment, when the obtained operation information is operation information of a tool and it is determined that the tool is completely placed in the device, it is first determined whether a light curtain is shielded before the tool is completely placed in the device, and if the light curtain is shielded before the tool is completely placed in the device, which indicates that the light curtain is in a normal state, it is determined whether a shielding object exists to affect the safety of the device operation according to the shielding state of the light curtain (when the tool is completely placed in the device). Before the tool is completely placed into the equipment, the shielding state of the light curtain can be determined according to the receiving state and the receiving time of each infrared receiving tube in the receiver of the light curtain. In a specific embodiment, before the tool is completely placed in the device, the process of determining the shielding state of the light curtain may be: before the tool is completely put into the equipment, whether each infrared receiving tube in the receiver of the light curtain receives infrared light in a first time period is judged, if the infrared receiving tubes in the receiver of the light curtain do not receive the infrared light in the first time period, whether each infrared receiving tube in the receiver of the light curtain receives the infrared light in a second time period is continuously judged, if the infrared receiving tubes in the receiver of the light curtain receive the infrared light in the second time period, the fact that the light curtain is blocked before the tool is completely put into the equipment is judged, namely, the fact that the light curtain is in a normal state is judged. The first time period is earlier than the second time period, and the first time period and the second time period can be determined according to the size of the tool, the distance between the light curtain and the position where the tool needs to be placed, the speed of placing the tool and the like.
If the infrared receiving tube in the receiver of the light curtain receives the infrared light in the first time period and/or the infrared receiving tube in the receiver of the light curtain does not receive the infrared light in the second time period, the light curtain is not blocked before the tool is completely put into the equipment, namely the light curtain is invalid. At the moment, the equipment is controlled to output light curtain prompt information so as to prompt an operator to check whether the light curtain is normal. The light curtain prompt information can comprise the fault type of the light curtain, operation information corresponding to different fault types and the like, so that an operator can quickly determine the fault type and the fault reason of the light curtain based on the received light curtain prompt information after receiving the light curtain prompt information and can timely perform corresponding processing. The fault type and the fault reason of the light curtain can be determined according to the receiving and sending state information of the infrared correlation tube on the light curtain, and then the light curtain prompt information is generated according to the determined fault type. Such as: if the infrared receiving tube in the receiver of the light curtain receives the infrared light in the first time period, the installation position of the light curtain may deviate or be unreasonable; if the infrared receiving tube in the receiver of the light curtain does not receive the infrared light during the second time period, the surface of the light curtain may need to be cleaned, or the infrared receiving tube may be damaged or the infrared transmitting tube may be damaged. The light curtain prompting information is not limited to be output in the form of voice, characters or images, and can also be output in the form of an indicator light, and the prompting light can correspondingly prompt an infrared receiving tube or an infrared transmitting tube with a fault.
In addition, after the operation information detected by the operation sensing device is acquired, if the acquired operation information is operation information of the tool to be taken out, in order to ensure validity of detection of the light curtain, before the operation sensing device detects that the tool is completely taken out, whether the light curtain is in a normal state or not needs to be detected, that is, before the operation sensing device detects that the tool is completely taken out, whether the light curtain is blocked or not needs to be detected. The determination process of whether the light curtain is blocked is the same as the determination process when the operation information of the tool is acquired, and the description is omitted here. If the light curtain is blocked before the operation sensing device detects that the tool is completely taken out, the light curtain is in a normal state at the moment, and in order to prevent the light curtain from being broken down when the next tool is put in, the step of obtaining the operation information detected by the operation sensing device is continuously executed, the operation of putting in the tool is detected again, and the light curtain is continuously detected to be blocked before the tool is completely put in the equipment; if before the operation induction system detects that the tool is completely taken out, the light curtain is not detected to be shielded, which indicates that the light curtain has a fault, the obstacle in the dangerous area cannot be effectively detected. Therefore, the step of controlling the equipment to output the light curtain prompt information to prompt whether the light curtain is normal or not is executed, so that an operator of the equipment can solve the problem of the fault of the light curtain in time, and the normal operation of the equipment is prevented from being influenced.
This embodiment detects the operating information who gets to put the frock and detect the pressure information of frock through frock induction system through operation induction system, with according to whether pressure information confirms whether the equipment is put into completely to confirm whether normal according to the state of sheltering from of light curtain before the frock is put into completely that the light curtain is normal, and after the equipment is put into completely to the frock at normal and light curtain, confirm whether there is the potential safety hazard according to the state of sheltering from of light curtain, can in time effectively detect the validity of light curtain and in time get rid of the potential safety hazard according to the state information of frock, the security when having improved equipment operation.
Referring to fig. 4, fig. 4 is a flowchart of a third embodiment of the apparatus control method according to the present invention, and the third embodiment of the apparatus control method according to the present invention is proposed based on the first embodiment. In this embodiment, the device control method includes the steps of:
step S21: acquiring operation information detected by an operation induction device;
step S22: if the acquired operation information is the operation information of the tool and the light curtain is shielded before the tool is completely placed into the equipment, detecting whether the light curtain is shielded again when the tool is completely placed into the equipment;
step S23: if the light curtain is not shielded when the tool is completely put into the equipment, controlling the equipment to normally operate, and executing the step of acquiring the operation information detected by the operation sensing device;
step S24: and if the light curtain is shielded when the tool is completely placed into the equipment, controlling the equipment to stop running, and controlling the equipment to output tool prompt information so as to prompt an operator to check whether the placed tool is correct, whether the position where the tool is placed is correct and/or whether the operator is in a safe area.
In this embodiment, if the acquired operation information is operation information of the tool and the light curtain is blocked before the tool is completely placed in the device, when the tool is completely placed in the device, whether the light curtain is blocked is detected again. If the light curtain is shielded when the tool is completely put into the equipment, the equipment is controlled to stop running, and the potential safety hazard is avoided. In addition, in order to facilitate an operator to remove potential safety hazards in time, the equipment is controlled to stop running and output tool prompting information at the same time, so that the operator is prompted to check whether the placed tool is correct or not, whether the position where the tool is placed is correct or not and/or whether the operator withdraws from a safety area after the tool is placed and the like. Before the equipment is controlled to output the tool prompt information, the reason why the light curtain is shielded can be determined according to the size information and the position information of the tool which is put in and the form information of the shielding object, and then the tool prompt information is generated according to the determined reason.
Specifically, size information and position information of a tool to be placed and morphological information of different types of shelters are preset, and then the reason why the light curtain is sheltered is determined according to the size information, the position information and the morphological information of the shelters detected by the light curtain. If the detected shielding object is determined to be a tool according to the preset form information, if the size information of the detected tool is inconsistent with the size information of the preset tool, the tool which is put in may not be the tool which needs to be put in, that is, the reason why the light curtain is shielded is a tool error, and prompt information is generated based on the error reason, wherein the prompt information may include information such as the error reason and the model and the specification of the correct tool; when the detected shielding object is determined to be a tool according to the preset form information, and the size information of the detected tool is consistent with the preset size information, if the position information of the detected tool is inconsistent with the preset position information, the position where the tool is placed is not correct, and prompt information comprising the error reason and correct position information required to be placed by the tool is generated based on the reason of the error position of the tool; because the tool can be distinguished from the body of the operator and other objects except the tool based on the form information of the detected shelter, when the detected shelter is a certain part of the body of the operator, the position of the operator is wrong, and tool prompting information containing the error reason and the position information of the safe area is output to prompt the operator to withdraw from the safe area; when the detected sheltering object is other objects except the tool, the position error of the object which is not the tool is described, and at the moment, tool prompting information containing the error reason and the position information of the safe area is output to remind an operator to move the other objects except the tool out of the safe area. Of course, the reason why the light curtain is blocked may include one of the above three reasons, and there may also be three reasons at the same time.
It should be noted that the step of controlling the device to output tool prompting information to prompt an operator to check whether the placed tool is correct, whether the position where the tool is placed is correct, and/or whether the operator is in a safe area may be performed while controlling the device to stop operating, or may be performed after controlling the device to stop operating. The former can be when detecting the shelter very first time with feedback information output for the operator to the operator in time gets rid of the potential safety hazard, and the latter sends the prompt message after the shut down, can guarantee the stability of system.
In this embodiment, by acquiring the operation information detected by the operation sensing device, if the acquired operation information is the operation information of the tool and the light curtain is blocked before the tool is completely placed in the equipment, it is detected again whether the light curtain is blocked when the tool is completely placed in the equipment; if the light curtain is not shielded when the tool is completely put into the equipment, controlling the equipment to normally operate, and executing the step of acquiring the operation information detected by the operation sensing device; if the light curtain is sheltered from when the equipment is put into to the frock completely, then control equipment stall, and control equipment output frock prompt message to whether the suggestion inspection is put the frock correct, whether the position that the frock was put is correct and/or whether the operator is in safe area, make things convenient for the operator in time to discover and eliminate the potential safety hazard, not only can guarantee the security of equipment operation, and improved equipment operating efficiency.
