Detailed Description
An insulation test system for railway signal cables can be software or hardware. The insulation test system is used for controlling the starting and stopping of the insulation resistance of the test signal cable and the work of other circuits, and is also used for recording, storing, judging, displaying the tested data and the like.
The first embodiment:
as shown in fig. 1, the insulation test system for railway signal cables comprises a control module, M groups of insulation test modules, M groups of cable selection modules and a mutually exclusive cable selection matrix module, wherein the M groups of insulation test modules are connected with the control module and arranged in parallel, the control module controls the M groups of insulation test modules to perform insulation resistance test, and the M groups of cable selection modules are connected with the M groups of insulation test modules in a one-to-one correspondence manner.
Each group of insulation test modules comprises a high-voltage generating circuit module connected with the control module and a test circuit module connected with the high-voltage generating circuit module, and the test circuit modules are connected with the cable selecting modules of the corresponding groups.
As shown in fig. 2, in a medium railway station, assuming that 500 signal cables are connected to a railway distribution board, insulation test modules are dispersedly placed in the signal railway distribution board, and each group of insulation test modules corresponds to one row of connection terminals in the railway distribution board. A row of wiring terminals of the railway distribution board is provided with 1-13 wiring bases, each base is provided with 6 wiring terminals, and each wiring terminal is connected with a signal cable. Therefore, each wiring base can be connected with 6 signal cables at most, one row of wiring bases can be connected with 78 signal cables at most, one group of insulation test modules can test 78 signal cables at most in turn (in the embodiment, n in fig. 1 is 78 at most), 78 signal cables are correspondingly provided with one group of insulation test modules (namely, one high-voltage generation circuit module, one test circuit module and one cable selection module), each group of insulation test modules corresponds to one row of signal cables of a testing railway distribution panel, and the cable selection module can independently connect the test circuit module with each signal cable in a time-sharing way, namely, the insulation resistance of each signal cable can be tested one by one through the cable selection module. Of course, each group of insulation test modules is not necessarily arranged correspondingly according to a row of bases of the railway distribution board, and can be combined in any other favorable mode according to actual needs.
The method is characterized in that X groups of signal cables to be tested are supposed to be arranged (namely, the X groups of signal cables are arranged in the railway distribution board, each group of signal cables corresponds to one line of signal cables of the railway distribution board, each group of insulation test module corresponds to one line of signal cables of the railway distribution board to be tested), each group of signal cables is provided with N signal cables, each group of signal cables corresponds to one group of insulation test modules, namely, the X groups of signal cables correspond to the X groups of insulation test modules, and the cable selection module selects and connects one signal cable each time, so that any one of the N signal cables can be connected one by one.
Wherein M, N and X are both integers greater than 1, and M is greater than or equal to X.
When the insulation resistance test is carried out on the X groups of signal cables, the signal cables which cannot be subjected to the insulation test at the same time need to be identified by comparing with the exclusive cable selection matrix module. One railway station can be provided with a set of mutually exclusive cable selection matrix modules. The exclusive cables, namely two or several cables which can not be subjected to the cable insulation test, are combined by all the exclusive cable lists to form an exclusive matrix module.
Two signal cables existing in the signal cables are simultaneously tested for insulation to the ground, interference or damage can be caused to a signal system, and the signal cables cannot be simultaneously tested for insulation to the ground or be tested for insulation between every two. The insulation test mutual exclusion cable of any cable can be arranged in the insulation test system, the mutual exclusion cable can be a plurality of cables, and the mutual exclusion cable can not be tested simultaneously in the test process. The mutually exclusive cable selection matrix module can identify signal cables which cannot be tested simultaneously, is independent of the insulation testing module, and ensures that the signal system is not influenced in the grouping testing process.
The mutually exclusive cable selection matrix module is a table structure of software, as shown in fig. 3, and is placed in the control module as a module, when preparing for testing, a plurality of rows of signal cables are connected to the control module, and each row of signal cables is provided with a plurality of signal cables.
Before each cable to be tested is tested, the mutually exclusive cable selection matrix module is inquired, the test of the cables to be tested is skipped when the mutually exclusive cables are tested, and the protection effect that the cables to be tested and the mutually exclusive cables are not tested simultaneously is achieved. The mutually exclusive cables can be provided with a plurality of cables, wherein the 'and' in the mutually exclusive cables indicate that all the cables, namely the test cable cannot be tested simultaneously with any cable of the railway station, such as the X1 cable with the serial number of 1 in a table.
The control module simultaneously controls the X groups of cable selection modules to independently select and connect N signal cables one by one to prepare for testing; the control module compares and judges the signal cable selected to be connected into the cable selection module with the exclusive cable selection matrix module, marks the signal cable with the exclusive cable, and controls the cable selection module to disconnect the signal cable; then, the control module sends out an instruction and controls the X groups of insulation test modules to simultaneously perform insulation test on the X groups of non-mutually exclusive signal cables, namely, the signal cables of each group of insulation test modules simultaneously test the insulation resistance, and the steps are repeated to successively finish the test on all the signal cables in the group of insulation test modules; and the control module controls the insulation test module to perform insulation test on the remaining signal cables which are identified as the mutually exclusive cables one by one.
The cable selection module can be a relay matrix, can also be other device matrixes with a switch function, and can also be realized through a software switch. The cable selection module only connects one signal cable with the test circuit module at a time, and after the insulation test of the signal cable is completed, the next signal cable is connected. Because the exclusive cable is removed after the exclusive cable selection matrix module judges and identifies, the signal cables in different test combinations can be tested simultaneously. Therefore, the signal cables in the signal system can be grouped and simultaneously subjected to insulation test, and the test efficiency is greatly improved.
The control module sends out an instruction, the signal cables marked as the untested states are sequentially and one by one communicated with the test circuit module, the high-voltage generating circuit and the test circuit are started to work, and the insulation resistance of all untested signal cables is tested. The mutual exclusion cable is independent, each independent cable is connected with the test circuit module, and then the test is carried out, so that the signal system is not influenced.
