On concrete function, data acquisition unit, monitoring performance element and remote server have the effect that
Data acquisition unit is the Data Source of whole monitoring system, and the performance of data acquisition unit directly determines the performance of whole monitoring system.
Monitoring performance element is that the monitoring of on-the-spot side performs equipment, every primary cut-out one data acquisition unit of configuration.Monitoring performance element collection is from the data of data acquisition unit, storage data also show on display terminal with intuitive way in real time, the characteristic signals of analytical sampling, compare with the data in property data base in real time, can quickly dispose when data exist unexpected abnormality, and the trend of various performance datas is analyzed, the timely early warning when qualitative tendency is beyond the scope set.This monitoring performance element plays and also plays communication bridge beam action simultaneously, is responsible for that all kinds of initial datas are sent to remote server and carries out further data process, receives the control command from remote server.
Remote server is the brain place of whole monitoring system, and a set of remote server can be connected with multiple monitoring performance elements, manages multiple monitoring performance element simultaneously.Mechanical property data from the primary cut-out of each data acquisition unit different model collects and this, forms complete expert database and analyzes module.Manipulation order can also be assigned in real time by this remote server manipulation personnel and monitor performance element to each, it is achieved human-computer interaction.
In actual application process, this monitoring main function of system is to analyze primary cut-out switching characteristic in real time, monitor all kinds of accident, provide a rational anticipation standard to the switching characteristic trend of chopper, mainly following characteristic is analyzed:
A) the divide-shut brake speed of phase each to chopper, branch wire time, three-phase are crossed punching etc. and are automatically analyzed；
B) automatic marking chopper primary operating parameter；

During the carrying out practically of monitoring system, switching characteristic control function functionally divides and can be divided into four kinds of function monitors:
Oneth, urgent abnormal characteristic analysis
Urgent abnormal characteristic analysis refers to that switch abnormal characteristic when switch is in normally (i.e. switching Guan Bi) duty is analyzed, data acquisition unit real-time monitoring voltage current sensor, stroke sensor and the duty of actuator current sensor, sudden change monitoring to the voltage x current of switch both sides in real time provides whether warning message, record switch exist the phenomenons such as jump.
The second, static characteristics analysis
Static characteristics analysis refers to contact specificity analysis when switch is in normally (i.e. switching Guan Bi) duty, and now Main Analysis refers to the contact situation got an electric shock during switch conduction.The load state of voltage current transformer real-time pilot switch both sides and the signal(l)ing condition of actuator, gather these signals by data acquisition unit and draw real-time curve chart, supercomputing unit real-time analytical data spectrogram judges whether to shine into abnormal voltage current waveform etc. due to switch contact existing defects, such as poor contact of contacts
3rd, dynamic analysis
Dynamic analysis refers to switch specificity analysis when being in closure or openness duty, now Main Analysis stroke, average speed, just point, just and speed, energy storage state, point and brake current, three same periods, the spring parameters such as number of times and time, the work of this part mainly completes in data terminal.
During details, navigation analysis logical analysis program is:
Data acquisition unit power on ready after, high speed acquisition is from the signal of stroke sensor, after high-voltage switch gear actuator obtains action command, beginning action, now navigation analysis program starts action front travel position under action record, stablizes the information such as rear travel position, and overtravel position.
Voltage x current logging program logical analysis:
Data acquisition unit power on ready after, high speed acquisition from the signal of voltage-current sensor, with the current sensor of switch executive mechanism as reference point, records continuous print voltage/time time-domain signal, electric current/time time-domain signal
Time logging program logical analysis:
Data acquisition unit power on ready after, data acquisition unit is in ready state, and data acquisition unit monitors electric current, after voltage and stroke signal sensor actuation, data acquisition unit is in running order, records separating brake, the movement times such as combined floodgate, in case next step use, time precision is 1us.
Parameter calculation procedure logical analysis:
According to the voltage collected, electric current and stroke signal, counting subroutine may determine that this chopper is in closing a floodgate, or separating brake process.By stroke sensor can with analytical calculation chopper and total kilometres during separating brake, open away from parameters such as, the excess of stroke.By time logging program can with analytical calculation chopper and opening time, the time parameter such as bounce time.By that recorded and separating brake stroke with and the relation of opening time utilize formula: V0=△ S/ △ T (1) can calculate each speed parameter.The parameters such as switch spring number of times can be recorded by record chopper both sides current/voltage sensor signal.
4th. switching tendency specificity analysis switching characteristic analysis refers on the basis of above-mentioned real-time analysis, and by the data in the expert database that accumulation and the original empirical data of certain data obtain, the work of this part mainly realizes in remote server.By analyzing the characteristic states of switch in real time, the situation of switch characteristic variations is set a limit value, when system detects that switching characteristic exceedes this setting value, system proposes an indicative information, remind user's potential safety hazard that may be present, it is to avoid the further expansion of accident, reduce loss
