The logic control device comprises a central processing unit, an input unit and an output unit, wherein the input unit is coupled with the central processing unit through a resistance network, and the output unit connected with the central processing unit is coupled with a couple-in load through a photoelectric isolation module. The logic control device used for urban rail vehicles in the utility model adopts a logic control device which is specially designed for subway trains, and a controller and an input-output circuit in the device replace massive intermediate relays, time relays and circuitous routes in the original electrical cabinet, thereby improving the reliability and the maintainability of the system.
Description
Technical field
The utility model relates to a kind of logic control device.
Background technology
Present railcar logic control adopts relay to constitute the intermediate controlled circuit in a large number, and the characteristic of relay itself causes its fault to have contingency and not repeated, under the many situations of relay quantity, failure rate will obviously increase, and influence the operational reliability of system.
The used control unit of patrolling of main-line locomotive mainly is to replace the interior auxiliary reclay of relay cabinet at present, does not relate to train-line.For example, at present main-line locomotive is used, and to patrol control unit TYLCU-SS (TongYeLogical Control Unit for ShaoShan) series cab logic control device be to aim at that homemade Shaoshan series electric locomotive is designed and developed, as to be used for the logic control of electric locomotive car load intelligent logic control device, be intended to replace original locomotive direct current 110V contactor control circuit, replace original time relay on the locomotive, low-voltage electrical apparatus and a large amount of round about circuits such as auxiliary reclay.
Because there is not train-line in locomotive, logic control element replaces is low-voltage electrical apparatus and round about circuits such as the time relay, auxiliary reclay on this section locomotive.
The utility model content
The purpose of this utility model aims to provide a kind of logic control device that is used for city rail vehicle, owing on the every joint car of city rail vehicle relay cabinet is arranged all, and link to each other by a large amount of control train-lines between car and the car, therefore except replace the time relay in the relay cabinet with logic control element, outside low-voltage electrical apparatuses such as auxiliary reclay and the round about circuit, also need to communicate by the CAN bus between car and the car, reach the purpose of cancellation train-line, subway train is reduced because the fault that relay and train-line cause in actual motion, improve the degree of reliability of subway train.
The technical solution adopted in the utility model: a kind of logic control device that is used for city rail vehicle, comprise CPU (central processing unit), input block and output unit, wherein input block inserts CPU (central processing unit) through resistor network, and the output unit that is connected with CPU (central processing unit) inserts load through photoelectric isolation module.
Below each unit is further described:
Input block:, therefore, before carrying out the logic control computing, at first will handle through links such as the step-down of resistor network, voltage stabilizing amplitude limit, capacitor filtering, photoelectricity isolation because its input signal is direct current 110V signal.The input signal of every road 110VDC is converted to the 5V level signal, enters CPU (central processing unit) and participate in logical operation; The conversion of every road is finished in input block, has the hardware anti-interference design simultaneously, is not mistaken as normal input signal after allowing 10 milliseconds to seal in input circuit with interior peak voltage.
CPU (central processing unit): Software Anti-interference function etc. is controlled, is reached in the main completion logic computing of CPU (central processing unit), time-delay.The status input signal that this unit is mainly determined according to the actual condition of locomotive decides the state of each output.
Output unit: output unit is used for driving the various types of vehicles load.The mode of isolating with photoelectricity realizes the isolation of high low-voltage and the amplification of driving power simultaneously.
In sum, the logic control device that is used for city rail vehicle described in the utility model adopts the logic control device that designs for subway train specially, by installing inner controller and imput output circuit, substitute a large amount of auxiliary reclays, the time relay and circuitous circuit in the original regulator cubicle, thereby improve the Reliability ﹠ Maintainability of system.
Description of drawings
Fig. 1 is a logic control device theory diagram described in the utility model.
Fig. 2 is a logic control device train network topological diagram described in the utility model.
Embodiment
As shown in Figure 1, the logic control device that is used for city rail vehicle described in the utility model, CPU (central processing unit) and imput output circuit by control device inside, substitute a large amount of auxiliary reclays, the time relay and circuitous circuit in the original regulator cubicle, thereby improve the Reliability ﹠ Maintainability of system.Also the LED light by the control device panel shows the I/O state of city rail vehicle control device and the state of device itself etc., and wherein each pilot lamp corresponding a tunnel inputs or outputs, and can see the state of I/O so intuitively.
As shown in Figure 2, the part output signal of this device is also as the input signal of a kind of Vehicular intelligent substation (SKS), carry out the later working signal of logic determines to Vehicular intelligent substation (SKS) input by this device, comprise traction, urgent traction, braking, brake hard, fast braking or the like, thereby city rail vehicle is carried out by the ATO instruction of logical transition that this control device carries out or the train instruction of sending by primary controller.
Display device is the technology of existing logic control device, and input media is the existing I/O device of city rail vehicle.
The distinctive advantage of the utility model or good effect:
Replace the control ability that relay can improve train effectively with logic control element, practical solution original system is the insecure problem of relay under the big environment of the high vibrations of humidity;
Software Anti-interference function etc. is controlled, is reached in the main completion logic computing of CPU, the time-delay of patrolling in the control cell arrangement. CPU adopts the microcontroller with affluent resources; And I/O is abundant, the CPLD of flexible in programming, has simplified hardware circuit.
This device directly receives train signal by the I/O interface, does not take the city rail vehicle Internet resources, have simultaneously the information monitoring amount big, control succinct, fault and get rid of the advantages such as convenient.
