Abstract
The utility model discloses a kind of multi-functional expandable type PIS controllers for track traffic, including power circuit, main control chip and pinboard, the beneficial effects of the utility model to be：1. this product has concentrated the communication function of current existing master controller, and existing function of calling out the stops is focused on same PIS controllers, PIS controller hosts on other so compatible existing subway tramcars, the substitutability of product is provided and reduces product inventory pressure, different master controllers will not be used because application item is different.2. reserved communication interface and I/O interfaces meet other function expandings.When client has other demands, or else we change PIS controllers and motherboard in the case that, it is only necessary to change interface board just energy meet demand, the expansivity and replaceability so greatly improved, shortens the design cycle, improve the stability of product.
Description
Technical field
A kind of PIS controllers are the utility model is related to, are specifically a kind of multi-functional expandable type PIS for track traffic
Controller.
Background technology
With the development of track traffic, more and more cities start to build subway and tramcar, because every client
Difference is required to the communication pattern of PIS controllers, and the communication mode of existing single PIS controllers is relatively simple, versatility
It is not strong！Carry out PIS controller exploitations every time for different clients, the manpower of consuming, energy is very big, and product expands
Extensional is poor, it is sometimes necessary to overlapping development！And the more maintenances of type and production of product are more troublesome！
All more nervous, the more next high, work(of the stability requirement to product of the cycle request of exploitation of the client to product
It can require also to differ.To the real-time of product, the maintenance of log recording, product is all valued very much.
Utility model content
The purpose of this utility model is to provide a kind of multi-functional expandable type PIS controllers for track traffic, with
Solve the problems, such as proposed in the above background technology.
To achieve the above object, the utility model provides following technical solution：
A kind of multi-functional expandable type PIS controllers for track traffic, including power circuit, main control chip and switching
Plate, the main control chip connect power circuit, wheel pulse process circuit, I/0 mouthfuls reserved, I2C isolation circuits, RS232 respectively
Circuit, RS485 circuits, ETH circuits, TF card circuit, address circuit, USB circuit and indicator light circuit, pinboard connect electricity respectively
Source circuit, wheel pulse process circuit, I/0 mouthfuls reserved, I2C isolation circuits, RS232 circuits, RS485 circuits, ETH circuits and mother
Plate, the motherboard are also connected with converting interface.
Preferred solution as the utility model：The core element of the wheel pulse process circuit is 74HC393 chips.
Compared with prior art, the beneficial effects of the utility model are：1. this product has concentrated current existing main control
The communication function of device, and existing function of calling out the stops is focused on same PIS controllers, other so compatible existing ground
PIS controller hosts on iron tramcar, there is provided the substitutability and reduction product inventory pressure of product, will not be because of application item
Mesh is different and uses different master controllers.2. reserved communication interface and I/O interfaces meet other function expandings.When client has it
During his demand, or else we change PIS controllers and motherboard in the case that, it is only necessary to interface board just energy meet demand is changed, this
The expansivity and replaceability that sample greatly improves, shorten the design cycle, improve the stability of product.

All other embodiments obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1-4, in the utility model embodiment, a kind of multi-functional expandable type PIS for track traffic is controlled
Device processed, including power circuit, main control chip and pinboard, the main control chip connect power circuit, wheel pulse processing respectively
Circuit, I/0 mouthfuls reserved, I2C isolation circuits, RS232 circuits, RS485 circuits, ETH circuits, TF card circuit, address circuit, USB
Circuit and indicator light circuit, pinboard connect power circuit, wheel pulse process circuit, I/0 mouthfuls reserved, I2C isolation electricity respectively
Road, RS232 circuits, RS485 circuits, ETH circuits and motherboard, the motherboard are also connected with converting interface.
The core element of wheel pulse process circuit is 74HC393 chips.
The operation principle of the utility model is：Power circuit is mainly the 5V power supplys input:One be converted into 3.3V to
Master controller, second, exporting 5V isolated power supplies to RS485.
Address circuit：16 addresses can be represented come adjustment control device address, 4 tunnel address wires by toggle switch.
TF card interface connects TF card, for storing work log and the failure logging of product.
USB circuit upgrades for program, facilitates product up-gradation to safeguard.
Indicator light circuit uses 27 indicator lights, meets currently used and reserved follow-up other functions instruction, the later stage can
With self-defined.
The pulse signal that reserved wheel pulse process circuit inputs vehicle is handled, the identifiable level of microcontroller of output
Signal.
Reserved ETH circuits, ethernet circuit is a full duplex too net transceiver, and flank speed can reach 100MB/
S, and interface is connected to motherboard, it can so be communicated by exchanger with multiple equipment.
2 groups of RS485 interfaces are reserved to backboard, 2 groups of RS232 interfaces to backboard are according to the demand of client's reality come using wherein
Port communicate.
Reserved I/O circuits and I2C circuits are to backboard, if I/O interfaces deficiency can be expanded by I2C chips.
