Being embodied as when, laser detector is installed in the final position of runway, and controller passes through wired or wirelessly connects；Controller can be the equipment that single-chip microcomputer, computer, programmable logic controller (PLC) etc. are capable of being controlled laser detector and timer, and the electronic time unit that timer is usually electrically connected with the controller.Usually, match or running training when, it is required for a starting apparatus, this starting apparatus, being triggered when, can send starting singal (such as if starting pistol, can send sound being triggered when), this starting apparatus is also associated with a trigger simultaneously, this trigger can be triggered while starting apparatus sends starting singal, generates timing signal, by wired or wirelessly pass to controller.Controller is after receiving this timing signal, and triggering timing device starts timing.When athlete reaches home when, can through the laser detector that is arranged on runway, through when, it is possible to sensed by laser detector.And laser detector generates electrical signal of reaction after sensing human body, and this electrical signal of reaction is sent to controller.Controller, after receiving this electrical signal of reaction, generates and stops signal, and this stopping signal being sent to timer.Clocking information, after receiving stopping signal, is sent to controller by timer.
Carry out together, therefore generally, due to be probably many individuals race or training when, preferably, if many people need to arrive at terminal at different racing tracks, then just should be respectively mounted a laser detector at each racing track, each laser detector is all connected with controller；If many people are only different at block clearance time racing track, and racing track is identical arriving at terminal when, then only need a laser detector just can meet needs.Therefore, it can arrange multiple connectivity port at controller, this connectivity port is for connecting with laser detector.Need several laser detector, just install several on connectivity port.It addition, when many people are trained or race when, timer is timing when, after receiving stopping signal, can't really stop timing, but only be sent to controller by receiving the clocking information stopping the signal moment.Usually, having a few individual train together or race, timer is just able to receive that several stopping signal, then will generate same amount of clocking information and be sent to controller.This clocking information is athlete from the beginning of starting singal sends, and arrives at the time of terminal to athlete.
Furthermore it is preferred that shown in Figure 4, in the time set that this utility model embodiment is provided, it is also possible to connect display screen 50 and/or sound broadcasting device 60 on the controller.After controller receives clocking information, this clocking information can be shown by display screen, or be played back by sound broadcasting device.
The time set that this utility model embodiment is provided, by when athlete reaches home when, can through the laser detector being arranged on runway, through when, it is possible to sensed by laser detector.And laser detector generates electrical signal of reaction after sensing human body, and this electrical signal of reaction is sent to controller.Controller, after receiving this electrical signal of reaction, generates and stops signal, and this stopping signal being sent to timer.Clocking information, after receiving stopping signal, is sent to controller by timer.The precision of the detection of laser detector is high, and therefore the error of timing is little, and the when of timing, is automatically to be sensed by laser detector, it is not necessary to be individually equipped with timework personnel for the athlete on each racing track, saves people's force information.Meanwhile, the use of laser detector, controller and timer is for prior art, and the device of use is few, low cost.Thus, while reducing timing error, also save the human cost of timing, and cheap for manufacturing cost.
Shown in Figure 2, in the time set that this utility model embodiment is provided, laser detector includes: LASER Light Source 101, scanning means 102, by photodetector 103；
Described LASER Light Source 101 is used for sending laser beam, and is irradiated on described scanning means 102 by described laser beam；
Described laser beam can be reflected into a scanning plane by described scanning means 102；
The described described laser beam by photodetector 103 after sensing is reflected by described scanning means, and laser beam is blocked when, generate electrical signal of reaction.
Being embodied as when, LASER Light Source 101 is used for sending laser beam.This LASER Light Source 101 is closed, is not easily susceptible to the impact of external environment, and easily forms laser beam.And LASER Light Source 101 uses lower powered visible light lasers, such as He-Ne Lasers, semiconductor laser etc..And the laser beam that LASER Light Source 101 is sent is thinner, thus in order to improve the precision of scanning, it is to avoid because laser beam is meticulous, causing data bigger error occur, the laser beam emitted by LASER Light Source 101 is emitted directly toward scanning means 102.This scanning means 102 generally reflecting mirror etc. can reflect the reflecting mechanism of laser beam, LASER Light Source can be reflected away, and at the same time, the angle of reflecting mirror can change the most at a high speed, cause laser beam to be transmitted to different directions, ultimately form a fan-shaped scanning plane.And in order to control the rotation of reflecting mirror, it is also possible to rotary apparatus is installed on the mirror, this rotary apparatus can control reflecting mirror be perpendicular to scanning plane axle as axis, repeatedly swing in the range of predetermined angle, ultimately form scanning plane.
Shown in Figure 3, in the time set that this utility model embodiment is provided, it is then a kind of a kind of device that can produce electric current under the irradiation of laser beam by photodetector 103.Including: processor 104 and light receiving circuit 105；
Described processor 104 electrically connects with described light receiving circuit 105；
Described light receiving circuit 105 generates faradic current at described laser beam under irradiating, and described faradic current disappears when laser beam is blocked；
Described processor 104 for generating electrical signal of reaction when described faradic current disappears.
Implementing when, light receiving circuit 105 generally comprises a sensitive device, and this sensitive device can be photodiode, it is also possible to be the sensitive surface made of special material.No matter it is photodiode or sensitive surface, the signal of telecommunication can be converted optical signal under the irradiation of laser beam.And by bypass circuit, this signal of telecommunication is passed to processor 104.Wherein it is desired to it is noted that faradic current produced by light receiving circuit 105 is analogue signal, and the signal that processor 104 can process is digital signal, is therefore also associated with analog-digital converter 106 between processor 104 and light receiving circuit 105.This analog-digital converter 106 is for being converted from analog into digital signal by faradic current.When laser beam and by photodetector 103 between have laser when, light receiving circuit 105 can always produce a faradic current be sent to processor.And once having athlete from laser beam with by passing through between photodetector 103, laser beam is blocked, it is meant that light receiving circuit no longer produces faradic current, and now, faradic current disappears.And processor side is faradic current disappears when, generate electrical signal of reaction.
Turning also now to shown in Fig. 3, a scanning plane is reflected to form owing to laser beam can be scanned device 102, the rotation of timing scanning means 102 is quickly, by human eye apparently, the scanning plane formed all can be covered by laser beam at synchronization, but in fact, how soon have regardless of the swing of scanning means 102, at synchronization, the area that on scanning plane, only single laser light beam can cover just has laser beam, therefore, in order to ensure that laser beam is during scanning forms scanning plane, can can be by received by photodetector 103 in different scan positions, in the time set that this utility model embodiment is provided, each can be provided with multiple by the light receiving circuit 105 of photodetector 103.Wherein, multiple described light receiving circuits 105 all electrically connect with described processor 104；
Multiple described light receiving circuits 105 when being reflected into scanning plane, sense the described laser beam after described scanning means reflects in different scanning angles for described laser beam respectively；
Described processor is for receiving the faradic current that different described light receiving circuit is sent successively, and when not receiving described faradic current in Preset Time, generates electrical signal of reaction.
Implementing when, laser beam scanning plane to be formed, need in default angle, launch laser beam back and forth, therefore multiple light receiving circuit 105 is set, this light receiving circuit 105 is separately mounted in the different scanning angle of scanning plane.
Wherein, light receiving circuit 104 has two kinds of set-up modes:
1, ensure, regardless of which angle of laser beam directive, all have a light receiving circuit 105 can sense laser beam, therefore in the case of laser beam is not blocked, in each moment, all have at least one light receiving circuit 105 can receive faradic current.
2, every the default time, processor just can receive the faradic current once sent by different light receiving circuits 105.
And these light receiving circuits 105 are all connected with processor 104, it is meant that, once laser is blocked.No matter it is where being blocked at scanning plane, processor 104 all can be made at a time cannot to receive faradic current, or make processor 104 cannot not receive faradic current at Preset Time, i.e. mean that being in this athlete gone to has arrived at terminal.
Additionally, laser beam is made to form scanning plane, and multiple light receiving circuit 105 is set, still another advantage of the present invention: when at least two athlete almost arrives at terminal at synchronization when, athlete all can be recorded accurately by the moment of each light receiving circuit 105 on scanning plane, therefore, contrast be on earth which athlete more first arrive at terminal when, whom can first pass through scanning plane according to judge, need not as in prior art, the method being carried out playback verification by the picture captured by high-speed camera one by one is needed to judge.
It addition, see shown in Fig. 3 and Fig. 4, in order to judge athletic particular location (at a time, which position athlete is positioned in scanning plane on earth), processor is also associated with encoder 107.
Described encoder 107 electrically connects with described light receiving circuit 105；
Described encoder 107 is for encoding multiple described light receiving circuits 105, and sends coding information to described processor 104；
Described processor 104 is additionally operable to generate electrical signal of reaction according to described coding information.
Implementing when, encoder 107 is directly connected with light receiving circuit 105.When light receiving circuit 105 sends current signal to processor 104 when, encoder 107 the most also can think that processor sends coding information.If certain light receiving circuit 105 of a certain moment should send current signal to processor 104, but this signal is blocked, then processor will generate electrical signal of reaction according to coding information.
It should be noted that the electrical signal of reaction now generated may have multiple (athlete starts until last light receiving circuit terminates) from first light receiving circuit.
And during athlete runs, have the action got over before lifting lower limb, therefore, the when of in order to prevent athlete from going to terminal, crossing laser beam, can be arranged on the position that comparison is high by laser detector 10, the time set that therefore this utility model embodiment is provided also includes: channel frame.This channel frame is for setting up default height by laser detector 10.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; change can be readily occurred in or replace, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with scope of the claims.
