Abstract
The utility model discloses a locomotive logic control device based on DSP. The device comprises a digital signal processor DSP, a complex programmable logic device CPLD, a switching value input circuit, a switching value output circuit, a simulation signal input and output circuit, an analog-to-digital/digital-to-analog conversion circuit, SBSRAM, EEPROM, a communication circuit and an MVB interface, wherein the DSP is respectively in connection with the analog-to-digital/digital-to-analog conversion circuit, the SBSRAM, the EEPROM, the communication circuit and the MVB interface, and the CPLD is also respectively connected with the switching value input circuit and the switching value output circuit. By adopting the DSP with powerful function as a core part of the device, the device causes the system to greatly enhance the capacity of processing failure information; aiming at the defect that the DSP is weaker in interface-wire operational capacity, the device adopts the CPLD to complete the logic processing function of a single chip microcomputer in a system, thus simplifying the structure, improving the integration and increasing the reliability for the system, effectively ensuring the steadiness and reliability of a train in operation and improving the driving safety of the train.
Description
Technical field
The utility model relates to a kind of locomotive logic control device, particularly a kind of locomotive logic control device based on DSP.
Background technology
Traditional electric locomotive control circuit is made up of the critical pieces such as relay, contactor, switch, protection electrical equipment and power supply of master control electrical apparatus, various functions, and its repeat circuit just has auxiliary reclay, the time relay, voltage relay, current relay, oil flow relay, pressure switch etc.Control relay circuit principle and structure are all fairly simple, application is ripe, but the reliability of relay control mode is poor, control function is few, can not arbitrarily change control function, and the installation work amount is very big, and wiring is very complicated, when needs change control function, need rewiring.Even more serious is reaches 120km/h when above when locomotive speed, because the locomotive vibration aggravation, the vibration of relay contact also increases thereupon, makes the control circuit misoperation and causes fault.
The utility model content
For solving the situation that existing electric locomotive control circuit reliability is low, control function is few, wiring is complicated and debugging is difficult for, the utility model provides that a kind of reliability height, attainable control function are abundant, locomotive logic control device is easily debugged in wiring.
For realizing above-mentioned technique effect, the utility model comprises digital signal processor, the complex logic programming device, the switching value input circuit, the switching value output circuit, the simulating signal imput output circuit, modulus/D/A converting circuit, SBSRAM, EEPROM, telecommunication circuit and MVB interface, described DSP respectively with modulus/D/A converting circuit, SBSRAM, EEPROM, telecommunication circuit is connected with the MVB interface communication, described CPLD also respectively with the switching value input circuit, the switching value output circuit connects, and described simulating signal imput output circuit also communicates to connect with the simulating signal imput output circuit.
Technique effect of the present utility model is, has adopted the core component of powerful digital signal processor DSP as device, and system is increased greatly to the processing power of failure message; At the more weak shortcoming of DSP mouth line functipnal capability, the single-chip microcomputer that adopts complex logic programming device CPLD to finish system carries out the logical process function; Like this, make that system architecture is simplified, integrated level improves, reliability increases, guaranteed train steadily reliable in the operation way effectively, the security that has improved train driving.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
Referring to Fig. 1, the CPLD in the circuit is responsible for carrying out work such as rate signal detection, address assignment; It is connected with dsp bus by data bus.The dsp operation program loads by monolithic EEPROM, and running memory is monolithic SBSRAM; Sampled data reads, diagnostic result output is sent to the locomotive microcomputer system by bus through telecommunication circuit, carries out diagnostic result by the locomotive microcomputer system and shows and data dump, also can read existing detection data from the locomotive Control System of Microcomputer by this communication interface.Simulating signal IO interface in the circuit, AD conversion and DA change-over circuit are used for signals collecting such as the required vibration of fault diagnosis, impact, temperature, simulation control; Simultaneously, also exportable analog control signal is used to the control module that needs simulating signal to regulate; Thereby, the fault diagnosis functions of whole device and control function are expanded.
