The down-hole is a special production environment, and common PC can't directly enter the down-hole operation, comes the watch-dog operation but some places, down-hole need computing machine again.At present, a lot of embedded monitoring equipments appear on the market, the general pattern that adopts high-grade arm processor to add a TFT display screen.The intrinsic safety requirement can be reached after the special processing of circuit electrical specification in this pattern, the down-hole can be directly applied to.But the software and hardware of this series products generally all needs customization, and production cost is than higher, and is maintainable poor, system's fluctuation of service, poor compatibility.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of production cost lower, maintainable good, system is stable, compatible high mine explosion-suppression and intrinsic safety type computer installation.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of mine explosion-suppression and intrinsic safety type computer installation, comprise power supply module, essential safe type keyboard, speech conversion circuit, Signal Spacing change-over circuit, mine explosion-suppression casing and be installed in the interior technical grade panel computer of mine explosion-suppression casing, described power supply module provides the operating voltage of technical grade panel computer, speech conversion circuit and Signal Spacing change-over circuit, and the output signal of technical grade panel computer is utilized the output of wiring mouth after changing by the Signal Spacing change-over circuit.
Furtherly, in order to reach better security and reliability, the utility model comprises that also described power supply module comprises the two-way power supply, first via power supply adopts the AC/DC switch power module to be the power supply of technical grade panel computer, and it is speech conversion circuit and the power supply of Signal Spacing change-over circuit that the second road power supply adopts the less AC/DC switch power module of power ratio first via power.
Again furtherly, for the ease of connecting with other watch-dogs of down-hole, and it is undistorted to reach distant signal, the utility model comprises that again described technical grade panel computer is 15 cun LCD computer, adopt Socket479 framework C/M1.5GHZ super low-power consumption extra low voltage version processor, intel GM chipset, 1G SDRAM, operation Windows series mainstream operation system, described technical grade panel computer also provides 2 tunnel 10/100 self-adaptation Ethernet interfaces, 4 road RS485 communication interfaces, 1 tunnel extendible USB2.0 interface, 2 road PS/2 interfaces and 1 way word phonetic entry, output interface.
Further, in order better to realize the conversion between non-intrinsic safety signal and the intrinsic safety signal, the utility model comprises that also described Signal Spacing change-over circuit is made up of photoelectricity coupled circuit and USB electrical equipment isolator.
The beneficial effects of the utility model are, have solved the defective that exists in the background technology, and by adopting technical grade panel computer its inner framework and device, not only system is stable, and speed is fast, and is convenient to safeguard and software upgrading; Even and the power supply module that adopts makes that under the situation of positive and negative short circuit, the spark of generation can not ignited inflammable gas at the environment that contains a certain proportion of damp yet.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural framing synoptic diagram of the present utility model;
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of mine explosion-suppression and intrinsic safety type computer installation, comprise power supply module, essential safe type keyboard, speech conversion circuit, Signal Spacing change-over circuit, mine explosion-suppression casing and be installed in the interior technical grade panel computer of mine explosion-suppression casing, described power supply module provides the operating voltage of technical grade panel computer, speech conversion circuit and Signal Spacing change-over circuit, and the output signal of technical grade panel computer is utilized the output of wiring mouth after changing by the Signal Spacing change-over circuit.
Described power supply module comprises the two-way power supply; first via power supply adopts the bigger AC/DC switch power module of power that the alternating current of 127V is provided for the technical grade panel computer peripheral circuit relevant with some; the second road power supply adopts lower-powered AC/DC switch power module to convert the alternating current input power supplying of wide region to D.C. regulated power supply; pass through inner overvoltage fast then; current foldback circuit converts the direct supply of non-peace to the intrinsic safety direct supply; make it; even under the situation of positive and negative short circuit, the spark of generation can not ignited inflammable gas at the environment that contains a certain proportion of damp yet.
Described Signal Spacing change-over circuit is made up of photoelectricity coupled circuit and USB electrical equipment isolator, and the photoelectricity coupled circuit is realized the conversion between intrinsic safety signal and the non-peace signal; The USB electrical isolator converts the usb signal of non-peace to the intrinsic safety usb signal, satisfies the down-hole and uses.
