Specific implementation mode
The present invention is described below with reference to the accompanying drawings of the specification.
As shown in Figs 1-4, a kind of electrical cable intelligent school line apparatus, including primary control box 1 and secondary control box 7, wherein in the master control
It is respectively equipped with common end 6, power supply 2, detection table 4 and several main interfaces 11 on box 1, is in series on each main interface 11
One switch 12, the other end of the switch 12 are connect with one end of the power supply 2, and the other end of the power supply 2 is in series with master
Resistance 3 and display lamp 13, the other end of the display lamp 13 are connect with the common end 6;The display lamp 13 of setting is for side
Just the personnel in 1 this side of primary control box determine whether entire circuit is connected.
It is respectively equipped with common end 6 and several secondary interfaces 73 on the secondary control box 7, is gone here and there on each secondary interface 73
It is associated with indicating module, the other end of the indicating module is connect with the common end 6, and the indicating module is by 72 He of indicator light
Secondary resistance 71 is composed in series, and the resistance value of secondary resistance 71 is all different in each indicating module.
The detection table 4 is voltmeter 42, and one end of the voltmeter 42 is connected between power supply 2 and switch 12, described
The other end of voltmeter 42 is connect with the common end 6 on the primary control box 1;When the detection table 4 is ammeter 41, the electricity
Flow table 41 is connected with the main resistor 3 and display lamp 13.
Supply voltage measurement table 8 is equipped on the primary control box 1, the supply voltage measurement table 8 and the power supply 2 are simultaneously
Connection;The resistance value of the pair resistance 71 is ranked sequentially according to descending or ascending.
Its operation principle is:First, for the ease of illustrating, five main interfaces are only depicted on primary control box 1 in attached drawing
11, pair, which is controlled to correspond on box 7, depicts five secondary interfaces 73, and five interfaces, the number of interface are not only limited in actual production
Amount can be arbitrarily arranged, wherein five 11 corresponding circuits of main interface are major loop (a, b, c, d, e), five secondary interfaces 73 correspond to
Circuit be subloop (m, n, r, s, w).
Then, because there are one main resistors 3 in the series connection of one end of power supply 2, and on each subloop of secondary control box 7
It is in series with secondary resistance 71, and the resistance value of each secondary resistance 71 is different from, therefore the electric current in any one circuit all differs
Sample, while in pair controls box 7, the pair electricity in different circuit, 71 voltages shared also are different, therefore are logical in school line
What the reading of overcurrent table 41 or voltmeter 42 can determine connection is that circuit, to the school line work of complete paired cable.
When the pressure of power supply electricity 2 is 6V, the resistance value of main resistor 3 is 200 Ω, the resistance value of secondary resistance 71 is followed successively by 100 from w to m
When Ω, 200 Ω, 300 Ω, 400 Ω, 600 Ω, corresponding electric current in each circuit on subloop at this time, and secondary resistance 71 are held
The voltage of load is as shown in table 1:
Table 1
Then, the both ends of cable 5 are inserted into respectively in main interface 11 and secondary interface 73, by two of common wire 51 on cable 5
End connect that (wherein common wire is that construction school line is used for convenience, and being always equipped with one in most cables colours with common end 6 respectively
Different common wires), when the line of school, if the switch 12 on major loop a is closed, at this time if it is the indicator light on subloop r
72 is bright, then illustrates that corresponding with the subloop r secondary interface of the main interface 11 corresponding to major loop a 73 is same electric wire, at this time position
It is 3.6V in the reading of voltmeter 42 on primary control box 1, the reading of ammeter 41 is 10mA.
Therefore, in above process, school line work is carried out if it is two people, then the people positioned at 7 one end of secondary control box, it can
Just can determine that the secondary interface 73 being specifically connected on secondary control box 7 by indicator light 72;School line work is carried out if it is a people, then
It can determine that specifically connected in subloop is which by the reading of voltmeter 42 or ammeter 41.
In view of power supply 2 voltage with the time used it is elongated, voltage can also reduce accordingly, in order to avoid power supply
The variation of voltage, and cause ammeter 41 or voltmeter 42 reading and normal voltage in the case of the difference that reads, therefore in electricity
A supply voltage measurement table 8 in parallel, the voltage of power supply 2 is measured with this at source 2, then by being obtained after calculating different secondary times
The electric current of road, and voltage swing that each secondary resistance 71 is undertaken, so that line work in school is more accurate.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
