Description
Technical field
The utility model relates to a kind of device that checks, and particularly a kind of table tennis ball serving net checks device.
Background technology
In ping-pong contest, when the sportsman of grasp right to serve served a ball, if the ball net, after the judge found, this service did not include, and the sportsman of the grasp right to serve of making a binding court decision on civil or economic cases serves a ball again.But at in-situ match, various Effect of Environmental, it is improper to add that the judge observes, occur under the situation of net in service easily, the judge does not send call, and the sportsman who grasps right to serve that makes a binding court decision on civil or economic cases serves a ball again, thereby cause judge erroneous judgement, consistently dispute occurs.Oriental sports newspaper once reported first message " the table tennis hypersphere despot Tieling of making a noise?---the net penalty attracts national champion's curse ", scene is very chaotic, player and football fan are hot headed very much, let loose a stream of savage invective, and throw out thing without care.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of table tennis ball serving net to check device, relies on the whether existing many weak points of net of perusal ball to solve at present at ping-pong contest.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
The table tennis ball serving net checks device, comprising:
One is installed in the infrared transmitter on the side clamp, and the IR that this infrared transmitter sends is close to net top edge one side;
One is installed in infrared light receiver on the opposite side clamp, and this infrared light receiver receives the infrared light that infrared transmitter sends,
One is installed in the control cabinet on the referee's chair, be provided with power supply, control mainboard in this control cabinet, control cabinet is provided with alarm, a power switch, a starting switch, described power supply connects civil power by power switch and lead, power supply is given the control main board power supply, described infrared transmitter is connected the control mainboard with the infrared light receiver by lead, and starting switch is connected with the control end of control mainboard, and alarm is connected with the drive end of described mainboard.
Operation principle of the present utility model is: when service does not have net, the infrared ray that infrared transmitter sends is received fully by the infrared light receiver, processor in the control mainboard does not send alarm signal, match is normally carried out, if during service touching the net, table tennis passes infrared ray, stop the transmission of infrared ray to the infrared light receiver, the infrared light receiver sends a pulse signal just for the control mainboard, after processor in the control mainboard receives this pulse signal, through calculation process, judge this service touching the net, then send the voice suggestion of similar " this service touching the net " by alarm, the referee is then according to this voice suggestion, send oral judge's instruction, the sportsman who grasps right to serve that makes a binding court decision on civil or economic cases serves a ball again.Click starting switch simultaneously, starting switch sends a pulse for the processor of control mainboard, and processor cuts out alarm signal after receiving this pulse signal, waits for the signal of net next time.
The utility model can be judged whether net of table tennis exactly, substitutes to rely on judge's naked eyes to observe whether net of ball at present, makes and judges science more.The utility model is simple in structure, technology maturation, installation and very easy to use.
Description of drawings
Fig. 1 checks the infrared transmitter in the device and the scheme of installation of infrared light receiver for the net of the utility model table tennis ball serving.
Fig. 2 checks the electric principle schematic of device for the net of the utility model table tennis ball serving.
The specific embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, one infrared transmitter 2 is installed on a side clamp 1, at opposite side clamp 3 infrared light receiver 4 is installed, infrared transmitter 2 is connected with a control cabinet 6 by lead 5 with infrared light receiver 4, and control cabinet 6 is installed in a side of referee's chair 7.The IR 8 that infrared transmitter 2 sends is close to net 9 top edges one side, and infrared light receiver 4 receives the infrared light 8 that infrared transmitter sends.
Referring to Fig. 2, be provided with power supply 61, control mainboard 62 in the control cabinet 6, control cabinet 6 is provided with alarm 63, a power switch 64, a starting switch 65, described power supply 61 connects civil power 220V by power switch 64 and lead, power supply 64 gives the control mainboard 62 power supplies, infrared transmitter 2 is connected control mainboard 62 with infrared light receiver 4 by lead 5, and starting switch 65 is connected with the control end of control mainboard 62, and alarm 63 is connected with the drive end of control mainboard 62.
When service does not have net, the infrared ray that infrared transmitter 2 sends is received fully by infrared light receiver 4, processor in the control mainboard 62 does not send alarm signal, match is normally carried out, if during service touching the net, table tennis 10 passes infrared ray 8, stop the transmission of infrared ray 8 to infrared light receiver 4, infrared light receiver 4 sends a pulse signal just for control mainboard 62, after processor in the control mainboard 62 receives this pulse signal, through calculation process, judge this service touching the net, then send the voice suggestion of similar " this service touching the net " by alarm 63, the referee is then according to this voice suggestion, send oral judge's instruction, the sportsman who grasps right to serve that makes a binding court decision on civil or economic cases serves a ball again.Click starting switch 65 simultaneously, starting switch 65 sends a pulse for the processor of control mainboard 62, and processor cuts out alarm signal after receiving this pulse signal, waits for the signal of net next time.
Circuit structure, infrared transmitter 2, infrared light receiver 4, alarm 63 and all kinds of switch of the control mainboard 62 that the utility model adopts are the commercially available prod, are well known to those skilled in the art, and do not repeat them here.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
