Description
Affiliated technical field
The invention belongs to the railway security facility, especially railway passenger station platform forbidden zone safety means are made the field.
Background technology
Can realize both at home and abroad at present realizing that to getting into platform forbidden zone number the reporting for work of switch of automatic grading control do not see as yet.
Existing grading control switch is primarily aimed at industrial control field and relates to, and its typical case's representative mainly contains following two types.1, the pressure switch of U.S.'s Sol company, its pressure sensor are the combinations of a force balance type and piston type, and by the dividing plate of a softness and fixing O type seal ring seal, control range is from negative pressure 1kg/cm
2To 680kg/cm
2, dividing Multistage Control, controlled pressure is 680kg/cm to the maximum
22, the ps series pressure switch of Ou Bai instrument company production; Be divided into two kinds on diaphragm type pressure switch and piston-type pressure switch; Its principle is when measuring media pressure changes; Medium sensor changes the corresponding displacement of generation according to pressure medium makes active force on the sensitive switch application point through corresponding mechanism simultaneously, the corresponding generation displacement of sensitive switch contact point under this active force; The whole world also has the company of a lot of other production pressure switches; But their principle and function are basic identical; Be mainly used in oil, electric power, chemical industry, metallurgy, pharmacy etc. and need pressure controlled place; All be some meter types, can't be applied in the bigger place of area, be difficult to satisfy the on-the-spot instructions for use of railway.
Summary of the invention
In view of the above shortcoming of prior art, the objective of the invention is to design a kind of railroad platform forbidden zone diversity switch of realizing that automatic classification triggers, make it to overcome the above shortcoming of prior art.
The objective of the invention is to realize through following means.
A kind of railroad platform forbidden zone diversity switch of realizing that automatic classification triggers; Form by personnel's magnitude induction mechanism and stage circuit signaling gear; Said personnel's magnitude induction mechanism has a loading plate 2 identical with railroad platform forbidden zone area; Be respectively arranged with four elastic bearings 3 below four jiaos of loading plate, be provided with a sliding contact 4 below the loading plate middle part; Said stage circuit signaling gear is made up of vertical guide rod 5 resistance branch 6 different with the resistance that is arranged on different subregions with parallel way that is provided with, and the different subregions of said guide rod are made up of the insulation joint 7 that is embedded on the guide rod; One end of said sliding contact places the guide rod surface to constitute and is electrically connected.
Apparatus of the present invention compared with prior art have following characteristics:
(1) the grading control switch can adapt to the instructions for use in large tracts of land places such as railroad platform;
(2) can carry increasing progressively of number through loading plate, realize automatic grading control, and the entire system later period maintenance of being convenient to simple in structure;
(3) be convenient to realize automatic fitration and processing that the error of avoiding loading plate load unsteadiness to cause is disturbed to current signal through computer (single-chip microcomputer) system.
Description of drawings
Fig. 1 Fig. 2 Fig. 3 is a grading control schematic diagram of the present invention.
Fig. 4 is personnel's magnitude induction mechanism structure chart of the present invention.
Fig. 5 is personnel's magnitude induction mechanism structure chart of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
This switch grading control principle such as accompanying drawing 1, personnel's magnitude induction mechanism have a loading plate 2 identical with railroad platform forbidden zone area, are respectively arranged with four elastic bearings 3 below four jiaos of loading plate, are provided with a sliding contact 4 below the loading plate middle part.With instance analysis the operation principle of switch is described, personnel's 1 number on load, plate is different, and the pressure that on load, plate 2, produces is different, and as Fig. 1, Fig. 2 and Fig. 3 were expressed, upper end sliding contact 4 was different with the contact position of guide rod 5.Grade scale can be divided according to actual needs; As in this example, by each personnel's body weight m=70kg calculating, (g gets 10N/kg according to Hooke's law nkx=mgp; The number of springs that install every load, plate lower end of n representative; K is the stiffness factor of spring, and p is a number), the position that descends of upper end sliding contact (4) then
The span of the position x that upper end sliding contact 4 is descended be divided into 3 grades (0, x
1], (x
1, x
2], (x
2,+∞] and (x wherein
1, x
2, x
3Be the value of x when p is 1,2,3), can the confirming according to actual needs of hierarchical level.For between different sinker, the resistance of its rear end contact is also inequality, if x ∈ (0, x
1], then connect resistance R
1, if x ∈ (x
1, x
2], then connect resistance R
2, if x ∈ (x
2, x
3], then connect resistance R
3, ultra-thin insulation joint 7 is set with resistance R on the guide rod 5 of lower end
1, R
2, R
3Keep apart, wherein R
1, R
2, R
3Resistance value different (can select the size of resistance value according to actual needs), under the different pressures effect, the resistance sizes of place in circuit is just different like this, the size of current that produces in the circuit is also different.As work as resistance R
1, R
2, R
3During the difference place in circuit, the electric current of generation is respectively I
1, I
2, I
3, computer triggers different files according to the size of current strength, when current strength is I
1The time, trigger first grade file, when current strength is I
2The time trigger second grade file, when current strength be I
3The time, trigger three grades of files.Utilize signal of telecommunication processing single chip 8 to realize grading control, the interference of avoiding load, plate carrier instability to cause simultaneously through calculation process according to the size and the Changing Pattern of current strength.
Construction of switch is formed like accompanying drawing 4 with shown in Figure 5; The present invention relies on circuit to carry out the grading control switch mainly to be made up of two parts; A part is personnel's magnitude induction mechanism such as Fig. 4; Comprise that mainly load, plate 2, elastic bearing are sliding contact 4 compositions of spring 3 (stiffness factor of required spring can be selected according to the needs of practical application), upper end, sliding contact is L shaped structure.Substructure is as shown in Figure 5; The stage circuit signaling gear mainly is made up of vertical guide rod 5 resistance branch 6 different with the resistance that is arranged on different subregions with parallel way that is provided with; The different subregions of guide rod are made up of the insulation joint 7 that is embedded on the guide rod, and an end of sliding contact 4 places guide rod 5 surfaces to constitute and is electrically connected, the resistance R of different resistance values
1, R
2, R
3(number of required resistance branch 6 and the size of resistance value all can be selected according to actual needs) and ultra-thin insulation joint 7, signal of telecommunication processing single chip 8 formed, and this switch simple in structure is easy to exploitation and realizes.
