Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A foldable illuminating lamp is provided with a foldable lamp post, the lamp post stands when illumination is needed, the lamp post falls when illumination is not needed, in the process of standing or falling of the lamp post, barriers such as people, twigs, electric wires and the like can be generated in the moving range of the lamp post to block the standing and falling of the lamp post, and accidents can occur if the action of the lamp post is not stopped immediately. In the related art, in order to prevent the occurrence of the accident, the following two methods are generally used to detect the obstacle: firstly, arranging sensors, such as a travel switch or a proximity switch, at one or more positions of a lamp post, judging that an obstacle exists and then stopping the lamp post when the sensor touches or approaches the obstacle when the lamp post acts; in the mode, due to the arrangement position of the sensor and the performance of the sensor, the detection range is small, the whole action range is difficult to cover, and meanwhile, the detectable barrier type is limited, for example, a travel switch needs to be exposed and also needs to be subjected to waterproof treatment, and a proximity switch has strict limitation on the texture type of the barrier, is generally effective only on metal objects and can only detect the metal barriers.
Secondly, through range unit, for example laser range unit, utilize swing arm formula telecontrol equipment to drive range unit and do fan-shaped motion, the fan-shaped within range and the distance of barrier when scanning the lamp pole action with this mode. For example, once scanning is performed immediately after the lamp pole is erected, distance data of a plurality of points in a fan-shaped action area are stored, the distance data are taken out for comparison on the premise that the lamp pole needs to be laid down, and if the data are not changed, the laying-down action is executed; the method has high complexity, can be realized only by combining mechanical, electronic and software, and has higher manufacturing difficulty and maintenance cost. In addition, due to the reasons of small market, slow technical development and the like, no folding type lighting lamp with an anti-pinch detection device is available in the market at present.
Based on this, the foldable lighting device and the foldable lighting system provided by the embodiment of the invention can be applied to a foldable device with the functions of detecting obstacles or preventing clamping.
To facilitate understanding of the present embodiment, a foldable lighting device disclosed in the present embodiment will be described in detail first, and as shown in fig. 1, the foldable lighting device includes: a base 1 and a lamp post 2; one end of the base is connected with one end of the lamp post through a rotating shaft 3; the other end of the lamp post is provided with at least one light beam emitter 4; at least one light beam receiver 5 is arranged at one end of the lamp post close to the base; the light beam receiver is used for receiving the light beam 6 emitted by the light beam emitter;
the base may be a base including a housing in which various modules may be disposed. The lamp post can be a liftable lamp post; the light pole can be raised after being erected, and after use, the light pole is lowered first and then laid down. The rotating shaft is used for realizing the folding action of the lamp post and the base; the light beam emitted by the light beam emitter can be infrared light, laser light and the like. The light beam emitted by the light beam emitter is received by the light beam receiver arranged at the other end of the lamp post, wherein each light beam emitter has a corresponding light beam receiver for receiving the light beam. The light beam emitted by the light beam emitter is generally positioned in the action range of the lamp post and can move along with the action of the lamp post. The number of the light beam receivers and the number of the light beam transmitters are the same, and the number of the light beam receivers and the number of the light beam transmitters can be one or more.
The light beam transmitter and the light beam receiver can be arranged at any position of two ends of the lamp post, but the light beam receiver is required to be ensured to be capable of receiving the light beam emitted by the light beam transmitter, and the light beam is required to be arranged in the surrounding area of the lamp post.
For each light beam receiver 5, when the lamp post acts, if the light beam 6 emitted by the light beam emitter and received by the light beam receiver 5 does not meet the preset condition, the action of the lamp post 2 is stopped.
The preset conditions can be set according to the attributes of the light beams and the actual application scene, specifically, after a starting instruction is received, the rotating shaft can drive the lamp post to do standing or lodging actions, meanwhile, the light beam emitter can emit the light beams, the light beam receiver starts to receive the light beams, and for each light beam receiver, if the energy of the light beams received by the light beam receiver is obviously reduced, the light beams are not received, the light beam receiver can control the rotating shaft to stop acting, and then the lamp post is stopped to act.
It should be noted that, if the light beam received by the light beam receiver always meets the preset condition, after the lamp post moves to the designated position, for example, the lamp post falls down to the base, stands up to be perpendicular to the base, and the like, the rotating shaft stops moving, fixes the lamp post at the current position, and simultaneously closes the light beam emitter and the light beam receiver; in addition, if the lamp pole is in the falling state, the height of the lamp pole needs to be reduced firstly, the light beam transmitter and the light beam receiver are started firstly, whether the lamp pole has an obstacle in the descending direction or not can be detected in the descending process of the lamp pole, and if the obstacle exists, the lamp pole is stopped immediately.
The invention provides a foldable lighting device, comprising: a base and a light pole; one end of the base is connected with one end of the lamp post through a rotating shaft; the other end of the lamp post is provided with at least one light beam emitter; at least one light beam receiver is arranged at one end of the lamp post close to the base; the light beam receiver is used for receiving the light beam emitted by the light beam emitter; and for each light beam receiver, when the lamp post acts, if the light beam emitted by the light beam emitter received by the light beam receiver does not meet the preset condition, the lamp post acts. In the mode, the light beam transceivers are arranged at the two ends of the lamp pole, the light beams can be received by the light beam transceivers in the lamp pole action process, whether barriers exist in the lamp pole action direction or not is judged, when the barriers block, the lamp pole action is stopped, accidents are prevented, the mode can accurately detect the barriers when the lamp pole acts, the detection precision is improved, and the user experience is improved.
The present embodiment provides another foldable lighting device, which is implemented on the basis of the above embodiments, wherein the light beam receivers 5 correspond to the light beam emitters 4 one to one; the light beam 6 between each of the corresponding light beam emitters 4 and light beam receivers 5 acts with the light pole 2.
The light beam receiver and the light beam transmitter are fixedly arranged at two ends of the lamp post, and each light beam transmitter corresponds to one light beam receiver, so that light beams between the light beam transmitter and the light beam receiver which correspond to each other can be parallel to the lamp post, and the light beams can be always parallel to the lamp post along with the action of the lamp post. Of course, the light beam emitter and the light beam receiver may have deviation in the installation position of the lamp post, so the light beam may not be parallel to the lamp post, but the light beam always moves along with the lamp post, so as to realize the overall scanning detection of the whole lamp post motion range.
With continuing reference to the schematic structural diagram of the foldable lighting device shown in fig. 1, the other end of the lamp post is further provided with an illuminating lamp 7; the beam emitters 4 comprise a plurality of ones, respectively mounted in front of and behind the lighting lamps 7; wherein, the front of the illuminating lamp 7 is the falling direction of the lamp post 2, and the back of the illuminating lamp 7 is the rising direction of the lamp post 2.
When the lamp pole moves in the standing direction, the light beam transmitter arranged behind the illuminating lamp and the light beam receiver corresponding to the light beam transmitter are started, and the light beam emitted by the light beam transmitter moves along with the movement of the lamp pole to scan and detect the whole lamp pole in the standing range. When the lamp pole moves in the lodging direction, the light beam transmitter arranged in front of the illuminating lamp and the light beam receiver corresponding to the light beam transmitter are started, and at the moment, the light beam emitted by the light beam transmitter moves along with the movement of the lamp pole, so that the whole lamp pole is scanned and detected in the lodging range. And when the lamp post falls down or stands up, the light beam transmitter and the light beam receiver corresponding to the light beam transmitter are closed.
The light beam transmitter and the light beam receiver mounted on the light pole are mainly described below.
In one possible embodiment, the number of beam emitters is two; the light beam emitted by the light beam emitter is a light beam with a specified width; the designated width is consistent with the width of the light pole.
It should be noted that the light beam emitter generally includes a plurality of kinds, and the emitted light beam also includes a plurality of kinds, which may be a straight light beam, a plane light beam with a certain width, and the like. Therefore, when the light beam emitted by the light beam emitter is a plane light beam, the number of the light beam emitters may include two. The two light beam transmitters are respectively arranged in front of the illuminating lamp and behind the illuminating lamp, and similarly, light beam receivers which can completely receive two parallel light beams emitted by the two light beam transmitters are respectively arranged at the corresponding positions of the other end of the lamp post. The light beam emitted by the light beam emitter is the light beam with the width consistent with that of the lamp post, the light beam can cover the action range of the whole lamp post, the problem that the detection range is not complete due to insufficient light beam width is avoided, the detection range of the obstacle is improved, and the detection precision is further improved.
In another possible embodiment, the number of beam emitters is greater than two; and a plurality of light beam emitters arranged in front of or behind the illuminating lamp and emitting total light beams with the width consistent with that of the lamp post.
If the light beam emitted by the light beam emitter is a straight light beam, at the moment, if only one light beam emitter is respectively arranged in front of and behind the illuminating lamp, the range which can be scanned by the light beam is small, the light beam cannot completely cover the width and the action range of the whole lamp post, and if the obstacle is arranged at the edge of the lamp post, the obstacle cannot be detected by the light beam receiver at the moment, therefore, the number of the light beam emitters is usually more than two, and a plurality of light beam emitters, for example, three light beam emitters are respectively arranged in front of or behind the illuminating lamp, so that the light beam emitted by the light beam emitters can cover the width of the whole lamp post, namely, the width of the total light beam emitted by the light beam emitters is consistent with the width of the lamp post. The mode improves the detection range of the barrier, and further improves the detection precision.
In order to further ensure the safety of the foldable lighting device in the working process and simultaneously improve the range of detecting obstacles and the detection precision, the lamp post comprises a liftable lamp post; the top of the liftable lamp post is provided with an obstacle detection module (not shown in the attached drawings); the obstacle detection module is used for detecting whether the liftable lamp pole has an obstacle in the lifting direction in the lifting process of the liftable lamp pole; if yes, a reminding signal is sent out, or the lifting lamp pole stops acting.
The obstacle detection module generally includes a radar (an electronic device for detecting a target by using electromagnetic waves), which has a wide detection range and can detect the size and distance of an obstacle, and the electromagnetic waves emitted by the radar are not a parallel beam but a scattered beam in the ascending direction of the lamp post, so that the detection range is wide. If an obstacle is detected in the lifting direction of the lamp post, whether the lamp post stops operating or not can be judged according to the size of the obstacle, the distance between the radar and the obstacle and other information. Or the lamp pole can be stopped to act when the obstacle is detected directly.
In one possible implementation mode, if the size of the obstacle is smaller than the preset size and the distance from the radar to the obstacle is smaller than the preset distance, a reminding signal is sent out; otherwise, the lamp pole is stopped. If the size of the obstacle is smaller than the preset size, or the distance between the radar and the obstacle is smaller than the preset distance, a reminding signal is sent out; otherwise, the lamp pole is stopped. The preset size and the preset distance can be set according to actual needs.
Generally, a liftable module is arranged in the lamp post, when an obstacle is detected, the obstacle detection module sends a stop action signal to the liftable module, and the liftable module stops the action of the liftable lamp post after receiving the stop action signal.
The present embodiment further provides another foldable lighting device, which is implemented on the basis of the above embodiments, and mainly describes the principle of detecting obstacles, and the base 1 further includes a switch module 8 and a motor 9; the light beam receiver 5 is connected with the switch module 8; the switch module 8 is connected with the motor 9; the switch module 8 is used for controlling the power supply of the motor 9; the motor 9 is used for controlling the action of the lamp post 2.
The switch module can be a relay, a switch circuit and the like; the above-mentioned motor generally includes a motor control circuit; the motor is connected with the rotating shaft. Referring to the schematic diagram of the obstacle detection process shown in fig. 2, if the light beam emitted by the light beam emitter and received by the light beam receiver does not satisfy the preset condition, an obstacle detection signal is sent to the switch module; and after receiving the obstacle detection signal, the switch module cuts off the power supply of the motor so as to stop the lamp post.
The obstacle detection signal can be a control instruction and used for controlling the switch module to cut off the power supply of the motor, specifically, when the obstacle is detected, the light beam receiving device sends the obstacle detection signal to the switch module, after the switch module receives the obstacle detection signal, the power supply of the motor can be directly cut off, so that the rotating shaft stops rotating, and a signal for stopping running can be sent to the motor control circuit, so that the motor stops running, the rotating shaft stops rotating, and the lamp post stops acting. The mode uses the sensor to emit a beam moving along with the action of the lamp pole as a medium, and realizes the comprehensive scanning detection of the action range of the whole lamp pole along with the action of the lamp pole, so that the obstacle detection can be realized in the action range of the whole lamp pole, and the detectable obstacle type is wide. And has the characteristics of low cost, simple structure and simple and clear principle.
In order to improve the practicability of the device and the experience of the user, referring to another schematic diagram of the obstacle detection flow shown in fig. 3, after the lamp post stops operating, if the light beam receiver receives a light beam meeting a preset condition, the light beam receiver sends a start signal to the switch module, and the switch module receives the start signal and recovers the power supply of the motor, so that the lamp post continues to operate.
Under the general condition, when the obstacle is detected, after the lamp pole stops acting, the light beam transmitter and the light beam receiver are closed, after the lamp pole is normally started again by manpower, the lamp pole can start acting again, the light beam transmitter and the light beam receiver can be opened again, in order to improve the practicability of the device and the experience of a user, after the lamp pole stops acting, the light beam transmitter and the light beam receiver can not be immediately closed, whether the obstacle exists in the current position can be continuously detected, if the obstacle is removed, after the obstacle does not exist in the current position, the light beam receiver can send a starting signal to the switch module, the switch module receives the starting signal, the power supply of the motor is recovered, and the lamp pole continues acting.
In order to save resources, after the lamp pole stops acting, the light beam transmitter and the light beam receiver can continue to work within a specified time, and after the specified time is exceeded, if obstacles exist, the light beam transmitter and the light beam receiver can be automatically turned off. Or sending out a prompt signal to remind people to remove the obstacle.
Similarly, when the lamp post stops lifting, the radar can continue to work within a specified time, and if the obstacle is removed within the specified time, the lamp post can continue to lift; if the obstacle is not removed within the specified time, the radar is turned off.
In order to further improve the practicability of the device and the experience of the user, the base further comprises a voice output module 10, referring to a schematic diagram of an obstacle detection flow shown in fig. 4, the voice output module 10 is connected with the light beam receiver 5; the light beam receiver is also used for sending an obstacle detection signal to the voice output module; and the voice output module outputs a reminding signal after receiving the obstacle detection signal.
In order to enable personnel to know the action condition of the lamp pole in real time, when the obstacle is detected, the personnel can be reminded in real time, so that the personnel can remove the obstacle through manual work, and the lamp pole is guaranteed to continue to act.
The voice output module can also be connected with the obstacle detection module, and the obstacle detection module is also used for sending an obstacle detection signal to the voice output module; and the voice output module outputs a reminding signal after receiving the obstacle detection signal.
