Embodiment
With reference to accompanying drawing 1,2, the utility model receives outside remote signals by switching value I/O interface, by the electronic relay module signal is isolated, and through programmable logic array module logic is recombinated, and imports the CPU processing module then; The host computer software operation can make the automation of transformation substations remote signalling amount of leaving export a certain road or a few road simultaneously by the RS232 interface, and pulse width, recurrence interval, startup interval, the pulse number on a few roads also can be set; The comparison system to the time module and communication module input quantity, the CPU processing module converts analog quantity to digital quantity and handles, and gives host computer by communication module with signal feedback at last.
[0008] remote signalling quantity of state input test: the amount of the leaving terminal correspondence of instrument is linked on the terminal of the measurement and control unit that will test, and inserts instrument from on-the-spot cut-off stream voltage, the DC voltage that applies should trigger the remote signalling switch motion.A deciliter test is carried out on available a few roads simultaneously in the operation, selects the required test number (TN) that carries out and maximum latency to test Loss Rate and the qualification rate of remote signalling.
Resolution test between different remote signalling: the amount of the leaving terminal correspondence of instrument is linked on the terminal of the measurement and control unit that will test, and inserts instrument from on-the-spot cut-off stream voltage, the DC voltage that applies should trigger the remote signalling switch motion.Arrange in the operation test the remote signalling number, start and interval time, pulse width, maximum latency to test the resolution between several remote signalling.
Two survey resolution test between action: the amount of the leaving terminal correspondence of instrument is linked on the terminal of the measurement and control unit that will test, and inserts instrument from on-the-spot cut-off stream voltage, the DC voltage that applies should trigger the remote signalling switch motion.Arrange in the operation test remote signalling number, action interval time, start the resolution between twice action testing interval time, maximum latency certain road remote signalling.
The snowslide test: the amount of the leaving terminal correspondence of instrument is linked on the terminal of the measurement and control unit that will test, and inserts instrument from on-the-spot cut-off stream voltage, the DC voltage that applies should trigger the remote signalling switch motion.The reaction time that the remote signalling group is inferior, maximum latency is come proving installation of test is set in the operation simultaneously.
In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop on the protection domain of the utility model requirement.
