Abstract
The utility model discloses a reclosure device for an electric brake. The reclosure device comprises a single chip and an electromagnet installed on the electric brake, wherein the electromagnet is connected with the single chip via a drive chip, and a storage, an interface chip and a keyboard are further connected to the single chip; and the device further comprises a display arranged at one side of the electric brake, wherein the display is connected with the single chip. The reclosure device disclosed by the utility model takes the single chip as a core, and keeps communication with an upper computer in real time via the interface chip; once a power system is failed, the upper computer sends a fault location result to the single chip to perform operational processing in the first time, and the single chip can be used for judging whether the circuit has a transient fault or not according to the trip condition of the circuit, and processing. The device is simple in structure, good in stability, convenient to install and debug, and low in cost.
Description
Technical field
The utility model belongs to electric power control field, is specifically related to a kind of electric brake coincidence arrangement.
Background technology
In line fault of electrical power system, surpassing 70% fault is single-line to ground fault, wherein all is transient fault more than 80%, so correct failure judgement type and to overlap electric brake be the important behave of guaranteeing the power system safety and stability operation.But belong to permanent fault if overlap, bring great harm will for system and equipment,, will be of great benefit to normal operation of system and device security if can distinguish permanent exactly and transient fault.
Summary of the invention
At the defective or the deficiency of existing control device, the purpose of this utility model is, a kind of SCM Based electric brake coincidence arrangement is provided, can discriminating fault types, improved suitable line length.
In order to realize above-mentioned task, the utility model is solved by the following technical solutions:
A kind of electric brake coincidence arrangement comprises single-chip microcomputer and the electromagnet that is installed on the electric brake, and electromagnet is connected with single-chip microcomputer by a chip for driving, also is connected with memory, interface chip and keyboard on single-chip microcomputer; This device also comprises the display that is arranged on electric brake one side, and described display is connected with single-chip microcomputer.
Other technologies characteristics of the present utility model:
Described single-chip microcomputer adopts the MSP430F149 single-chip microcomputer.
Described interface chip adopts the SP3220 chip.
Described memory adopts the 24LC02B chip.
Described display adopts the MG-12232 Liquid Crystal Module.
Described chip for driving adopts the ULN2003 chip for driving.
The utility model is core with the single-chip microcomputer, keep in communication in real time by connecting mouthful chip and host computer, in case electric power system is broken down, host computer just sends to single-chip microcomputer with the fault localization result and carries out calculation process in the very first time, if single-chip microcomputer judges that electric power system is a transient fault, then close a floodgate again by electromagnet.This apparatus structure is simple, and good stability is convenient to Installation and Debugging and cost is low.
Description of drawings
Fig. 1 is an annexation schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection range of the present utility model.
Defer to technique scheme, as shown in Figure 1, a kind of electric brake coincidence arrangement comprises single-chip microcomputer and the electromagnet that is installed on the electric brake, and electromagnet is connected with single-chip microcomputer by a chip for driving, also is connected with memory, interface chip and keyboard on single-chip microcomputer; This device also comprises the display that is arranged on electric brake one side, and described display is connected with single-chip microcomputer.
In the present embodiment, single-chip microcomputer adopts the MSP430F149 single-chip microcomputer of TI company.This is a kind of novel l6 position reduced instruction set computer single-chip microcomputer, and nearly the Flash ROM of 60KB and the RAM of 2KB are arranged.Internal resource is abundant, and A/D converter, temperature sensor, WatchDog Timer, 2 l6 bit timing devices, 6 Shu of being integrated with l2 position 200kb/s go into Shu and go out 2 serial communication interfaces of Duan Kou ﹑ and JTAG program debugging interface.Thereby, make the peripheral circuit of adaptive reclose device significantly reduce, simplified the circuit of system, wiring becomes simple and convenient, has also improved the stability and the antijamming capability of whole system.
Described interface chip adopts the SP3220 chip, and the effect of this chip is to finish communicating by letter between single-chip microcomputer and the host computer; Break down as circuit, host computer can send to single-chip microcomputer with the fault localization result and carry out calculation process in the very first time.
Described memory adopts serial storage 24LC02B chip, is used for storing and Backup Data, and recording equipment operational factor and logout etc. are so that inquiry.
Described display adopts the MG-12232 Liquid Crystal Module to realize, but this module indication range is 122 * 32 dot matrix, has adopted two ED1520F0A chip for driving, makes man-machine interface more directly perceived and intelligent; Display can show the operating state of current circuit in real time, if circuit breaks down, then by the display circuit of display device fault message.
Described chip for driving adopts the ULN2003 chip, and this chip is a kind of high withstand voltage, big electric current Darlington array, and characteristics such as have current gain height, operating voltage height, temperature range is wide, carrying load ability is strong are used for drive magnet work.
Described keyboard effect is to set the single-chip microcomputer running parameter, reset etc.
During this device busy, single-chip microcomputer is kept in communication in real time by interface chip and host computer, in case the faulty circuit tripping operation that is short-circuited, host computer just sends single-chip microcomputer with the fault localization result and carries out calculation process in the very first time.Single-chip microcomputer is determined the time that electric brake overlaps according to the fault localization object information, utilizes the chip for driving drive magnet that electric brake is closed again then.If circuit still tripped after electric brake closed, illustrate that then fault is non-transient fault, this moment, single-chip microcomputer no longer carried out closing operation, by display output circuit fault message, and fault message is transferred to host computer by interface chip, in time handle to remind the staff.
The electronic devices and components that the utility model adopts are known product, and those skilled in the art are according to the i.e. concrete connected mode of electronic devices and components as can be known of the technical solution of the utility model.
