Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
Due to security reason and guarantee train normally travel, exist between the pit where station platform and track for a train
Yellow line is labeled with safe distance, namely Line for Train ground, forbids placing object between yellow line and station platform edge
And forbid personnel to stand, therefore at the train station detection can not be set to set between the corresponding yellow line of platform end channel and station platform
Standby or detecting instrument has detected whether invader's entrance.
For these reasons, invader has been detected whether using ultrasonic sensor as detection device in the embodiment of the present invention
Into station platform end channel, Fig. 1 is a kind of invasion of station platform end channel according to an exemplary embodiment
The structural representation of person's identifying system, as shown in figure 1, the system includes ultrasonic sensor 131 and ultrasonic sensor 131

Optionally, transceiver passes through wired connection and/or wireless connection with total transceiver 111.Optionally, according to transceiver
Determine to use wired connection or wireless connection with the distance between total transceiver 111, apart from remote use wireless connection, distance
Near use wired connection.
Ultrasonic sensor, for receiving reflected signal, reflected signal is that ultrasonic signal encountered and produced after object；Root
The distance between object and ultrasonic sensor are determined according to reflected signal；Whether detecting distance is less than alarming value；If detect away from
From less than alarming value, then whether detection receives the number of times of reflected signal more than pre-determined number；Make a reservation for if detecting number of times and being more than
Number of times, it is determined that object is invader.
Optionally, ultrasonic sensor is additionally operable to when receiving alarm signal, sends ultrasonic signal.
Ultrasonic sensor 131 is arranged on the entrance of station platform end channel, station platform 130 and track for a train 120
Adjacent side is provided with ultrasonic sensor.
Optionally, ultrasonic sensor 131 is arranged in the safety zone of station platform.Such as, the ground of station platform
On be labeled with yellow line, the region between yellow line and station platform edge be danger zone, other regions be safety zone, ultrasonic wave
Sensor is arranged on the region beyond the region between yellow line and station platform edge.
Optionally, the porch of station platform end channel is provided with vertical rod, and a ultrasonic sensor 131 is arranged on one
The transceiver being connected with ultrasonic sensor 131 is additionally provided with individual vertical rod, in vertical rod.Optionally, the height of vertical rod is less than fire
Height on station console where high-tension bus-bar, generally, the height of vertical rod is 1 meter.
If there is track for a train 120 both sides of station platform 130, the shielding of the porch of platform end channel at the train station
The two ends on column 132 all set ultrasonic sensor 131.
If the side of station platform 130 is track for a train 120, side does not have track for a train, such as：Side is wall 140, then
The side adjacent with track for a train 120 sets ultrasonic sensor.
When it is invader that ultrasonic sensor, which determines object, alarm signal is sent to total transceiver by transceiver, always
Transceiver receives alarm signal, and alarm signal is sent to control computer.
Total transceiver 111 and control computer 112 are arranged on control centre 110, and control computer 112 is used to monitor, control
The working condition of each ultrasonic sensor 131 is made, the alarm signal that processing ultrasonic sensor 131 is sent, and record are super
Sonic sensor 131 sends the time of alarm signal.
Fig. 2 is refer to, the flow chart of the invader's recognition methods provided it illustrates one embodiment of the invention.The invasion
Person's recognition methods is applied in ultrasonic sensor as shown in Figure 1.As shown in Fig. 2 invader's recognition methods can include
Following steps：
Step 201, reflected signal is received, reflected signal is that ultrasonic signal encountered and produced after object.
Ultrasonic sensor operationally, persistently launches ultrasonic signal, after ultrasonic signal encounters object, produces anti-
Signal is penetrated, ultrasonic sensor receives reflected signal.
Optionally, ultrasonic sensor launches ultrasonic signal when receiving reflected signal.
Step 202, the distance between object and ultrasonic sensor are determined according to reflected signal.
Ultrasonic sensor determines the distance between object and ultrasonic sensor according to reflected signal.
Optionally, ultrasonic sensor is according to transmitting ultrasonic signal and receives the time difference between reflected signal, and
The velocity of sound, determines the distance between object and ultrasonic sensor.Such as：Ultrasonic sensor is in t1 receptions to reflected signal
And continue to send ultrasonic signal, and in t2 receptions to reflected signal, the velocity of sound is m, then object and ultrasonic sensor it
Between distance be (t2-t1) * m/2.
Step 203, whether detecting distance is less than alarming value.
Whether the distance between ultrasonic sensor detection object and ultrasonic sensor are less than alarming value.
Optionally, alarming value is the distance between ultrasonic sensor and platform edge.Such as：Alarming value is
1.5 meters.
Step 204, if detecting distance is less than alarming value, whether detection receives the number of times of reflected signal more than predetermined
Number of times.
If ultrasonic sensor, which detects distance, is more than alarming value, illustrate place of the object beyond platform, object is
Train.
If ultrasonic sensor detects distance no more than alarming value, whether the number of times that detection receives reflected signal is big
In pre-determined number.
Due to may have at station platform end channel be not invader chaff interference enter, such as：There is bird to fly over, at this
In the case of kind, it is not necessary to object is judged as into invader, therefore also needs to detect whether the number of times for receiving reflected signal is more than
Pre-determined number.
If detecting number of times no more than pre-determined number, illustrate object not to be the chaff interference of invader.
If detecting number of times more than pre-determined number, it is invader to illustrate object, performs step 205.
Step 205, if detecting number of times more than pre-determined number, it is determined that object is invader.
Optionally, ultrasonic sensor is sent to total transceiver by transceiver and alarmed when it is determined that object is invader
Signal, total gimmick device sends the alarm signal received to control computer, and subsequent treatment is carried out by control computer, than
Such as：Staff is reminded to go to corresponding pit, or, control loudspeaker send caution sound.
In summary, invader's recognition methods provided in an embodiment of the present invention, by receiving reflected signal, believes according to reflection
Distance between the sensor between object and ultrasonic wave number is determined, when distance is more than alarming value, detection receives reflected signal
Whether number of times is more than pre-determined number, and when the number of times for receiving reflected signal is more than pre-determined number, it is invader to determine object；Solution
Having determined in the prior art, monitoring station platform end channel is by being accomplished manually, the problem of monitoring efficiency is low；Automation is reached
Station platform end channel is monitored in real time and whether automatic decision has invader's invasion, improves the effect of monitoring efficiency and accuracy rate
Really.
