Description of drawings
Fig. 1 is the overall annexation figure of the device of remote conduction measurement of the present invention.
Embodiment
Further specify embodiments of the invention below in conjunction with accompanying drawing.
See also shown in Figure 1ly, the device of remote conduction measurement of the present invention comprises control module 1, and with the test module 2 of control module 1 wireless connections.Control module 1 is expanded 9 ports altogether, and each port connects a wireless data transmission receiver module, and each intermodule adopts different frequency ranges, and each port connects a test module 2 by the wireless data transmission receiver module.
The connection terminal 23 that test module 2 comprises a plurality of test modules 21, is connected with test module 21, and the test jack 24 that is connected with connection terminal 23; Test module 21 comprises a plurality of test cells that are connected in series 22.Different test modules 21 is made of 4～6 test cells that are connected in series 22 respectively, each test cell 22 is responsible for the test of 49 test points 3, while 1 pair of control module is respectively tested module 21, test cell 22 and test point 3 and is numbered, and whole test system has formed topological structure thus.
Test point 3 on the different measured bodies is connected to by different test adaptor heads in the test jack 24 of standard of this device, and the test jack 24 of standard is connected to connection terminal 23, and test module 21 connects the p-wire that comes out and also is connected to connection terminal 23.Owing to will be provided with each test point 3 of identification number and each pin position of test jack 24 connects one to one; And by connection terminal 23, each pin position of test jack 24 and the tie point under each test cell 22 are connected one to one, therefore, make the corresponding of tie point under the test cell 22 and each test point 3.
Control module 1 is by this corresponding relation, the numbering of each test module 21, test cell 22 and test point 3 is connected, make under the total system each test point 3 all possess specific numbering, and according to this numbering configuration testing point 3, and control corresponding test point 3 and test.After test operation is finished, return the test result of each test point 3 to control module 1, and export the signal condition of each fc-specific test FC point 3 according to mould group number, unit number and the test period of correspondence by numbered address.Such logical organization makes maintenance and extend testing point 3 be very easy to, need to increase test point 3, then only need in suitable test module 21, increase test cell 22 or newly-increased test module 21, and this test module 21 is got final product by the newly-increased port that the wireless data transmission receiver module is connected on the control module 1.Simultaneously because be that each test cell 22 is finished test alone, test point 3 numbers that the test duration of each test cell 22 only is connected with this test cell 22 are relevant, and there is no direct relation with the sum of the test point 3 of total system, therefore increase the number of the test point 3 of total system, can not have influence on the test duration of each test point 3, guarantee the speed of test.
Test cell 22 comprises signal controlling module 221, and signal controlling module 21 adopts complex logic chip EPM1270TC-144 able to programme, and this chip is responsible for the instruction that signal receives control module 4, carries out corresponding input-output operation according to instruction.
In each test module 21, each test cell 22 adopts being connected in series of four line serials, Transistor-Transistor Logic level, the signal controlling module 221 of back one test cell 22 is connected to the signal controlling module 221 of a unit, wherein be connected first test cell 22, interface protocol translation module 222 and wireless transport module 223 be equipped with, in order to receive the output signal of complex logic chip able to programme, all the other test cells 22 only are provided with signal controlling module 221.The test signal that each test cell 22 is received, the series connection switching of the signal controlling module 221 by each test cell 22, be transmitted to the interface protocol translation module 222 of the test cell 22 that is connected first at last by signal controlling module 221, be wirelessly transmitted to control module 1 via wireless transport module 223 again.Wherein interface protocol translation module 222 adopts the interface protocol escape chip ATmega8-16AC of module group, being responsible for to be the bit manipulation instruction of signal controlling module 21 based on the control module 1 instruction escape of ASCII character, and be that control module 1 is returned in the instruction of ASCII with the bit manipulation instruction escape that signal controlling module 21 is returned.
Wireless transport module 223 receives the instruction that control modules 1 send, and test result is converted into wireless data signal sends to control module 1.Wireless transport module 223 is for use equipment, and control mode is the control mode of serial ports, and by the modulation and demodulation of wireless chip, wireless transport module 223 is converted to transmission of wireless signals with serial data.What wireless transport module 223 adopted is the XE1205 of semtech company radio frequency SOC chip, work in the public frequency range of 433MHz, wireless module adopts semiduplex communication modes, and the module emissive power is that 10mW is at the spaciousness place, transmitting range can reach 1 kilometer, and coding chip adopts the Manchester's cde mode.
Workflow of the present invention is as follows:
Start test module 2 of the present invention and control module 1, the measured point is connected to this device, adopt the method that the test point 3 of measured body is realized grouped organizing among the present invention, per 49 tested pilots 3 constitute a test cell 22, the test cell 22 of some constitutes a test module 21, each test module 21 takies a radio port of control module 1, and each test point 3, test cell 22 and test module 21 be numbered, just can list the relation list of corresponding test module 21, test cell 22 and test point 3 thus.In control module 1 according to this relation table, by test mould group number, test cell number, test period configuration testing point 3, then successively according to configuration arrangement test point 3 relation lists, promptly beginning synchronous 22 pairs of test points 3 of each test cell after configuration finishes tests, this device provides a high level respectively to the test point 3 of all measured bodies of connecting, this level signal is a small-signal, avoid destroying measured body, in the time of a certain single-point of test, this device is put this level point low, then all points that are connected with this test point 3 all can be drawn and are low level, testing of equipment is fetched the level of all test points 3, and then the set of all low level points is the network with this test point 3.Control module 1 has been gathered after the data of the test module 21 under all test modules 2 by wireless transport module 223, organize into groups analysis, and shine upon according to given relation list, according to given mould group number, unit number and test period the result is put in order and exports, obtain promptly reflecting that all measured points connect the net list of situation.In test process, the test cell 22 between each test module 21 is finished surveying work synchronously, simultaneously.Centralized control by control module 1, guarantee to realize test synchronously between each test module 21, and test result returned to control module 1, and respectively test the number that module 21 comprises test cell 22 quantity and test module 21 by expansion, needing to realize the measurement of test point 3 numbers.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited to the appended claims.
