Abstract
The invention discloses a vehicle wheel pair triggering system. Two opposite type optoelectronic switches are respectively arranged at the two sides of a steel rail, a center position between the two opposite type optoelectronic switches is the same position as a center position of a photo taking measuring system used for carrying out photo taking measurement on wheels at the two sides of the steel rail, and when the wheels do not pass, signals emitted by emitters of the two opposite type optoelectronic switches can be just received by corresponding receivers. When the wheels pass, the condition that the signals emitted by the emitters of the two opposite type optoelectronic switches are simultaneously shielded shows that the wheels are positioned in the center position of the photo taking measuring system, and at the moment, the photo taking measuring system is triggered for detecting the wheels, so that the wheel information of the position is precisely caught and recorded.

When sheltering from the first correlation optoelectronic switch, first receiver 104 cannot receive the first transmitter 103 and be launched
Signal, now the first correlation optoelectronic switch be in low level " 0 " state;
When without wheel through the second correlation optoelectronic switch, second receiver 106 can receive described second
The signal that transmitter 105 is launched, now the second correlation optoelectronic switch be in high level one state, when wheel is through blocking
Firmly during the second correlation optoelectronic switch, second receiver 106 cannot receive the letter that the second transmitter 105 is launched
Number, now the second correlation optoelectronic switch is in low level " 0 " state;
When wheel is walked according to the direction of the first correlation optoelectronic switch to the second correlation optoelectronic switch, the is blocked successively
One correlation optoelectronic switch and the second correlation optoelectronic switch, no longer block until wheel leaves two correlation optoelectronic switches, this
During one first correlation optoelectronic switch and the second correlation optoelectronic switch level become turn to " 11 → 01 → 00 → 10 →
11 ", the level state that the measuring system real-time monitoring of taking pictures on the outside of rail gathers two correlation optoelectronic switches is arranged on, two pairs are penetrated
Wheel is in accurate trigger position, measuring system of taking pictures or other control system detections when formula optoelectronic switch level state is " 00 "
Triggering when to the level state of correlation optoelectronic switch being " 00 " is taken pictures or carries out follow-up process operation;
When wheel is walked according to the direction of the second correlation optoelectronic switch to the first correlation optoelectronic switch, the is blocked successively
Two correlation optoelectronic switches and the first correlation optoelectronic switch, no longer block until wheel leaves two correlation optoelectronic switches, this
During one first correlation optoelectronic switch and the second correlation optoelectronic switch level become turn to " 11 → 10 → 00 → 01 →
11 ", the level state that the measuring system real-time monitoring of taking pictures on the outside of rail gathers two correlation optoelectronic switches is arranged on, two pairs are penetrated
Wheel is in accurate trigger position, measuring system of taking pictures or other control system detections when formula optoelectronic switch level state is " 00 "
Triggering when to the level state of correlation optoelectronic switch being " 00 " is taken pictures or carries out follow-up process operation;
Measuring system of taking pictures can also gather the first correlation optoelectronic switch and the second correlation photoelectricity by real-time monitoring
Switch the level state change order during wheel is passed through to judge the directional information of wheel, such as when the first correlation photoelectricity
When the level state change order of switch and the second correlation optoelectronic switch is " 11 → 01 → 00 → 10 → 11 ", the traveling of wheel
Direction is the direction from the first correlation optoelectronic switch to the second correlation optoelectronic switch, when the first correlation optoelectronic switch and
The level state change order of two correlation optoelectronic switches for " 11 → 10 → 00 → 01 → 11 " when, the travel direction of wheel be from
The direction of the second correlation optoelectronic switch to the first correlation optoelectronic switch, measuring system of taking pictures or other control systems are supervised in real time
The level state for surveying two pairs of facilities of collection is analyzed process, so as to capture more fully wheel information.
The rail clip 107 is arranged on the bottom of the rail, respectively with first protective cover 101, the second metal
102 protective covers are fixedly connected.
Rail clip 107 is used for that the first protective cover 101 and the second protective cover 102 are fixed on rail, certainly
Other modes can be taken to be fixed, be not limited to a kind of this mode.
Above-mentioned car wheel-set triggering system mainly positions wheel using the level change of two correlation optoelectronic switches
Accurate trigger position.The transmitter and receiver of the first correlation optoelectronic switch and the second correlation optoelectronic switch can be embedded in gold
In category protective cover, such protective cover can play two correlation optoelectronic switch water proof and dust proofs of protection while rail is protected
Effect, two correlation optoelectronic switches can also be arranged higher than protective cover upper surface, as long as rational height is higher than rail
Upper surface, it is to avoid the signal of transmitter transmitting by rail block and cannot be received by the receiver to, but also to avoid two
Correlation optoelectronic switch is too many higher than rail upper surface, and otherwise two correlation optoelectronic switches are easily damaged while can also affect car
The normally travel of wheel, so in this embodiment we set the set location and the rail of the transmitter and receiver
The relative displacement of upper surface is 5mm, it is ensured that the signal of transmitter transmitting can be received in the position of receiver, be difficult
Damage does not interfere with the normally travel of wheel yet, and the numerical value of relative displacement can be using other numerical value, as long as meeting above-mentioned
Condition can be used.
System provided by the present invention is described in detail above, specific case used herein is to the present invention's
Principle and embodiment are set forth, and the explanation of above example is only intended to help and understands the method for the present invention and its core
Thought;Simultaneously for one of ordinary skill in the art, according to the thought of the present invention, in specific embodiment and range of application
On will change, in sum, this specification content should not be construed as limiting the invention.
