The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the present invention will be described in detail.
Shown in Fig. 1～3, the present invention includes the detection array, control unit 2 and the performance element 3 that are composed in series by several ultrasonic fault detection unit 1, ultrasonic fault detection unit 1, control unit 2 and performance element 3 link to each other by order wire order successively; Ultrasonic fault detection unit 1 is by ultrasonic transmitter-receiver 4, ultrasonic fault detection circuit 5, Cell processor 6, form from communication interface 7 and stabilized power supply circuit 8, ultrasonic transmitter-receiver 4, ultrasonic fault detection circuit 5 and Cell processor 6 link to each other successively, Cell processor 6 with link to each other with stabilized power supply circuit 8 from communication interface 7, ultrasonic transmitter-receiver 4 is used to transmit and receive ultrasonic signal; Ultrasonic fault detection circuit 5 is used to detect the signal situation of change of ultrasonic transmitter-receiver 4, transmits signals to Cell processor 6; Cell processor 6 is used for forming according to the situation of echo the result of detection data of this unit, and result data is sent to from communication interface 7; Be used for result data that receiving element treater 6 sends and the result of detection data of 7 next stage that send from communication interface 7 from next stage from communication interface, and with these result datas send to upper class ultrasonic fault detection unit 1 from communication interface 7, and finally be sent to the main communication interface 9 of control unit 2 from communication interface 7 by the ultrasonic fault detection unit 1 of upper class; Stabilized power supply circuit 8 is used to Cell processor 6 power supplies; Control unit 2 is made up of main communication interface 9, primary processor 10, driving interface 11 and voltage-stabilized power supply circuit 12, and main communication interface 9, primary processor 10 and driving interface 11 order successively link to each other, and voltage-stabilized power supply circuit 12 links to each other with primary processor 10; Main communication interface 9 is used to receive the result of detection data from each ultrasonic fault detection unit 1 that communication interface 7 sends of upper class, and these result of detection data are sent to primary processor 10; Primary processor 10 is used to receive the result of detection data of each ultrasonic fault detection unit 1, and after these result datas are carried out fusion treatment, whether track section 13 the occupy-place state is taken place form conclusion, sends command adapted thereto according to conclusion and is sent to driving interface 11; Driving interface 11 is sent actuating signal with appropriate form to performance element 3 according to instruction; Voltage-stabilized power supply circuit 12 is used for that the power supply after the voltage stabilizing is offered primary processor 10 to be used.Performance element 3 is used to finish the indication and the control action of " occupy-place state ".
Ultrasonic transmitter-receiver 4 in each ultrasonic fault detection unit 1 can be arranged a plurality of according to the needs of investigative range, with the investigative range that obtains high reliability and need.Ultrasonic transmitter-receiver 4 in the ultrasonic fault detection unit 1, ultrasonic fault detection circuit 5, Cell processor 6, be encapsulated in an enclosure interior from communication interface 7, stabilized power supply circuit 8, after certain degree of protection processing, draw order wire, power lead, to make things convenient for mounting arrangements.
As shown in Figure 4, be the mounting structure scheme drawing of detecting device of the present invention.Take characteristics according to track section 13 and train 14, several ultrasonic fault detection unit 1 are set, whether have train 14 to stop or process in order to survey to constitute detection array.The concrete installation site of ultrasonic fault detection linear array should meet railway boundary standard, must not influence section driving utilization, and the ultrasonic array detection range can cover whole sections, influenced by the seizure condition of adjacent orbit.When not having train 14 processes or stopping, ultrasonic fault detection unit 1 output result of detection data are " unit is vacant ", when train 14 passes through or rests in the track section 13, the ultrasonic pulse that ultrasonic fault detection unit 1 sends according to ultrasonic transmitter-receiver 4 is also surveyed the signal of car body reflection, and output result of detection data are " unit takies ".The result of detection data that the result of detection data and the next stage of this unit sent from communication interface 7 in the ultrasonic fault detection unit 1 send in the lump upper class ultrasonic fault detection unit 1 from communication interface 7, and finally send main communication interface 9 control unit 2 to from communication interface 7 by the ultrasonic fault detection unit 1 of upper class.After control unit 2 carries out fusion treatment to the result of detection data of each ultrasonic fault detection unit 1, whether track section 13 the occupy-place state is taken place form conclusion.If conclusion is " section takies ", control unit 2 sends command adapted thereto, the performance element 3 that is connected between the track of the left and right sides by driving interface 11 one of control moves, cause that original track circuit receiving unit generation state changes, the performance element 3 that is about to this detecting device is connected with the fixture wire of original track circuit receiving unit, forms the occupy-place indication of track section 13 by the local part of original track circuit system.Certainly, the track circuit system that also this instruction can be transferred to machine room is for further processing.
