Embodiment
In order to make those skilled in the art more clearly understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the human and machine interface unit of LKJ described in the utility model, it is a kind of human and machine interface unit of redundancy, comprise two mode of operations of redundancy: A modular system and B modular system, wherein in every modular system, a core board is all set, main computer unit core board being provided with CPU, a CPU and LKJ communicates.In the outside of each core board, be provided with the deck of the IC-card be connected with the CPU of core board, also should connect other devices used as human and machine interface unit needs such as display screen, push-button unit, storeies simultaneously.
The CPU of each core board is all arranged the single port controller be connected with CPU, the Ethernet of CPU electricity mouth is expanded to two-way Ethernet electricity mouth by it, the Ethernet switch of what this two-way Ethernet electricity mouth connected the is LKJ main computer unit of redundancy-type.In concrete connection procedure, in the two-way Ethernet electricity mouth of each CPU, connected mode is a wherein road Ethernet electricity mouth and connects the Ethernet switch of a main computer unit, another road Ethernet electricity mouth connects the Ethernet switch of another main computer unit, like this, can ensure that human and machine interface unit also can be applied under the state of cold standby, i.e. in the main computer unit of redundancy, each main computer unit all connects A modular system and B modular system two mode of operations.
Under normal condition; two mould work systems of human and machine interface unit are cold standby form; when one die worker does; another mould does not work; but; in some cases; such as need to upgrade data or data query time; two die worker's operation modes are needed all to open; this needs the mould do not worked to wake up, and the utility model, in the outside of every mould core board, is provided with the wake-up circuit be connected with the I/O mouth of this mould core board CPU; be used for waking up the work system of another mould, wherein wake-up circuit is connected with the power supply arranged in another mould.Wake-up circuit comprises the monostalbe trigger be connected with the I/O mouth of CPU specifically, monostalbe trigger connects one two input end four or door, two output terminals of two input ends four or door connect the power supply of a mould of wake-up waiting respectively by a metal-oxide-semiconductor, after wake-up circuit work, out-put supply, playing machine by electricity will need the system wake-up of the mould waken up.
As shown in Figure 2, one mould of work is B mould, A mould is waken up by B mould, the I/O of B mould is connected on the pin 1 of monostalbe trigger 74HC123, when by B mould input pulse, to electric capacity CA53 discharge and recharge, export a pulse connects to below or door UA36 at 74HC123 pin 13 simultaneously, and when the continuous input pulse of B mould, 13 pins of 74HC123 will export high level, and now, be connected with 13 pins or 8 pins of door 74HC32 and 11 pins export high level, the metal-oxide-semiconductor (UA38 and UA39) of loving with them is opened, the A mould power supply connected is made to have the output of 5V and 12V below, by the electrizer of A mould, A mould is waken up, two moulds connect the Ethernet switch of main computer unit, can intercom mutually.
