The input terminal (4) and the output terminal (9) are respectively connected with an electrical circuit board (6). The contactless program control device is used for an electrical control system of a railway electric drive locomotive.
Description
Technical field:
The utility model relates to the contactless program control device of a kind of railway internal combustion electric driving vehicle.
Background technology:
The history in the use of railway electric driving vehicle year surplus China existing 30, its most of parts have been realized production domesticization.DF4D type electric locomotive is the existing main vehicle of China, account for and using as a servant the more than half of vehicle, its production technology is to depend on import vehicle design such as early stage Germany, and electric control system is the logic control circuit that the electromagnetic switch by mechanical contacts such as contactor and relays constitutes.
Compare with program control technology with the conventional semiconductor technology, the major defect of Mechatronic control system is that appliance life is short, fault is frequent, maintenance cost is high, has caused low production efficiency, higher production cost and unsafe operation.For example: the electrical endurance national standard of relay switch is 105 times, 1600 yuans of 40 amperes electromagnetic contactor market price; The electrical endurance national standard of typical noncontacting switch solid-state relay (SSR) is 106 times, 360 yuans of the market price of 50 amperes of SSR; Program-controlled equipment adopts Programmable Logic Controller (PLC), 10 years its designed lives, is higher than other electrical endurance far away.
Summary of the invention:
The purpose of this utility model provides the contactless program control device of a kind of railway internal combustion electric driving vehicle, replace the part electrical equipment of the former design circuit of locomotive electric cad system with contactless solid-state relay (SSR) and Programmable Logic Controller (PLC), prolong locomotive electric cad system inaction interval, reduce the security performance of locomotive production and maintenance cost, raising locomotive operation.
Above-mentioned purpose realizes by following technical scheme:
The contactless program control device of railway internal combustion electric driving vehicle, its composition comprises: Programmable Logic Controller PLC, described Programmable Logic Controller PLC connects input circuit plate, output circuit plate and power supply, described input circuit plate is made of input terminal, forward direction backup switcher group and incoming level change-over circuit, described output circuit plate is organized, is then formed to backup switcher group and lead-out terminal by contactless solid-state relay SSR, and described input terminal is connected with electric circuit board respectively with described lead-out terminal.
The beneficial effects of the utility model:
1, the utility model locomotive electric cad system circuit employing modular design is convenient to install, is debugged and backup is switched and the later stage batch process.The locomotive electric cad system circuit adopts the system backup mode.Because the locomotive traffic that to be security high equipment, thus improved locomotive electric cad system with the primary circuit backup of working, master control realizes switching with backup by change-over switch.Former locomotive wire harness do not done revise, increase new wire harness and be connected with programmable control system.Locomotive electric cad system has 2 kinds of modes like this, and the one, contactless stored program control system, another is primary circuit relay working method, i.e. backup mode.Therefore reduced the locomotive electric cad system failure rate, compared, improved non-failure operation time more than 3 times, improved the security performance and the unfailing performance of locomotive operation with Electromechanical Control.
2, the utility model is compared with Electromechanical Control, reduces the locomotive electric cad system maintenance cost more than 4 times.
3, improve locomotive integral production efficient, prolonged the life-span of locomotive electric cad system, reduced production cost.

Fig. 2 is the circuit diagram of the utility model incoming level change-over circuit.
Fig. 3 is the circuit diagram of the utility model stored program controlled.
Embodiment:
Embodiment 1:
The contactless program control device of railway internal combustion electric driving vehicle, its composition comprises: Programmable Logic Controller PLC2, described Programmable Logic Controller PLC connects input circuit plate, output circuit plate and power supply 3, described input circuit plate is made of input terminal 4, forward direction backup switcher group 5 and incoming level change-over circuit 1, and described output circuit plate is made up of to backup switcher group 8 and lead-out terminal 9 contactless solid-state relay SSR group 7, back.Described input terminal 4 is connected with electric circuit board 6 respectively with described lead-out terminal 9.
Locomotive electric cad system has 2 kinds of modes, and the one, contactless stored program control system, another is primary circuit relay working method, i.e. backup mode.As shown in Figure 2, wire size is that P01XXX then is the signal sampling point, and wire size is that P00XXX then is the signal drive point.When working in contactless stored program control system, wire size is that P01XXX and wire size are that P00XXX disconnects, and when working in the relay working method, these points are connected by the PLC contactless control system.Wire size is P01XXX with wire size is that the lead of drawing of P00XXX is connected with the wiring point of the corresponding wire size of PLC contactless control system.
Contactless program control locomotive electric cad system is made up of the transformation circuit and the contactless stored program controlled of former locomotive electric cad system, contactless stored program controlled is made up of Programmable Logic Controller and solid-state relay, and the drive controlling of locomotive is finished jointly by improved locomotive electric cad system and contactless stored program controlled.
