Description of drawings
The module connection diagram of Fig. 1 pick-up unit of the present invention
Embodiment
Pick-up unit of the present invention utilizes single-chip microcomputer to be connected with computing machine by LAN (Local Area Network).The serial line interfaces such as RS232, RS485 of device are described to fixed port in the LAN (Local Area Network) by the communication server.Main website is by finishing installing the control of each serial line interface the visit of the port in the LAN (Local Area Network).Use a computer and go up the detection software of installing, by internet modifier three-phase standard alternating current source parameter, pulsed quantity output parameter, switching value output parameter, controlled quentity controlled variable input parameter and simulation table parameter etc., and reading unit test data and state.
As shown in Figure 1, three of pick-up unit intersects to be adopted the Function detection module and is realized by built-in three-phase standard source, the three-phase standard source can produce the three-phase normal voltage, the three-phase normalized current, three-phase is meritorious, three-phase is idle and power factor output, be used for the detection of terminal three-phase alternating current acquisition function, main website is by LAN (Local Area Network) control device output three-phase voltage and three-phase current (voltage, electric current can be distinguished phase-splitting and independently export), pass through selected communication mode and port again (as Ethernet, GPRS, RS232), by certain communication protocol, from tested terminal, read voltage, electric current, active power, reactive power, power factor etc.Compare input value and read value, calculate the measuring error of tested terminal.Parameters (as amplitude, frequency, phase angle, harmonic wave etc.) by changing input voltage, electric current also repeats said process, can draw the influence of each parameter to tested terminal measuring accuracy.
The remote signalling switching function detection module of pick-up unit is realized by built-in 8 tunnel remote control contacts input, the switching value input that pick-up unit provides is used to test the output of acquisition terminal pilot relay, change switching value and apply the effect that load can be simulated the control actual load, when tested terminal is carried out control output, the final impulse optor program action.Pick-up unit judges by the state variation of checking the switching value input port whether the relay of tested terminal moves.For example install the distant control function of sense terminals, device software checks whether its switching value input port has state variation after tested terminal is sent guidance command, if change then the distant control function of tested terminal is normal.Load may appear in terminal in actual motion heavier, can not draw away the phenomenon of lock, and pick-up unit is by increasing or reduce load variations in the method simulation actual motion of switching value load, in order to find out the peak load that tested terminal can be controlled.The switching value output signal that pick-up unit provides is used to test the remote signalling input of acquisition terminal, and device changes the state of its switching value delivery outlet, whether can correctly discern this state change in order to detect tested terminal.For example pick-up unit changes earlier its switching value delivery outlet and becomes short circuit by open circuit, and pick-up unit is inquired about tested terminal corresponding port by software whether the state change has also been taken place then, as being become " closing " by " branch " or becoming " branch " by " closing ".If there is then tested this function of terminal of respective change normal.
The step-by-step counting Function detection module of pick-up unit is realized by built-in 8 road count pulses output, 8 road count pulses provide various criterion frequency output signal to be used to detect acquisition terminal step-by-step counting input function, the different in width of pulse signal can be simulated different collecting devices and various intelligent electric energy meter, pick-up unit is by its pulse delivery outlet outputting standard pulse, and according to the electric flux of the calculation of parameter pulse output that is handed down to tested terminal, relatively call the electric energy value of receiving tested terminal together, calculate the step-by-step counting error of tested terminal.For example to issue the pulse constant by software to tested terminal be 1200 to pick-up unit, call together then and receive the current impulse electric charge truth of a matter of tested terminal, export 1200 pulses by the pulse output end mouth of device again, call together once more and receive the current impulse electric charge truth of a matter of tested terminal, than last time increasing the then tested terminal pulse counting of 1 degree accurately.If not 1 degree calculates (X-1) * 1200 (X is the increment of twice impulse electric charge truth of a matter), be the umber of pulse of the many meters of tested terminal or few meter.Device can be exported active pulse and passive pulse, and pulse, pulse width and frequency adjustable are exported in device software support fixed number or timing.
The warning function detection module of pick-up unit is realized by built-in 2 road aural warnings input, 2 tunnel audible alarm input interfaces that provide are used to test the alarm switch state of acquisition terminal output, during tested terminal generation alarm event, should make the alarm switch actuating of relay, pick-up unit is by checking the state variation of warning input interface, judges whether tested terminal has moved alarm switch.For example pick-up unit sense terminals power control alarm output, pick-up unit software issues the power definite value that is lower than current power to tested terminal, issues power control again and drops into order.Pick-up unit is checked the state variation of its warning input interface, and calls the alarm status of receiving tested terminal together.As the input interface state of reporting to the police changes, and calls together and receive tested terminal alarm is also arranged, and then terminal power control alarm function is normal.
In addition, the meter-reading function detection module of this pick-up unit realizes that by 2 tunnel 485 built-in simulation tables 2 tunnel 485 simulation tables can also provide the simulate electric energy meter that meets DL/T645-1997 and DL/T645-2007 agreement, are used to test the meter-reading function of acquisition terminal.The built-in simulation electric energy meter of pick-up unit can be by pick-up unit the order of checking meter of the corresponding tested terminal of RS485 interface, and table address had adaptive ability.The indicating value of simulation electric energy meter can change along with the requirement of pick-up unit software.For example during pick-up unit sense terminals meter-reading function, earlier by pick-up unit software with built-in simulation table assignment, wait for that then tested terminal checks meter.No matter why the address of checking meter of tested terminal is worth, and the simulation table all can be with the corresponding order of checking meter of the table address of correspondence.Pick-up unit software is called the indicating value of checking meter of receiving tested terminal together, and compares with the analog representation value, and the then tested terminal meter-reading function of unanimity is normal.
Pick-up unit provides and meets DL/T645-1997 and the DL/T645-2007 agreement RS485 interface of checking meter, and is used for the data comparison with other channel of checking meter.Pick-up unit can directly be copied and accepted the electric energy meter data by the RS485 interface of checking meter.These data can compare with the data of other channel of checking meter (as power line carrier, short-distance wireless etc.), in order to detect the correctness of other channel meter reading data of checking meter.For example whether pick-up unit sense terminals carrier channel is normal.Pick-up unit issues the order of tested terminal carrier meter reading by software, treat that it correctly copies back after, the RS485 that checks meter by pick-up unit directly copies back the electric energy meter data again.With twice meter reading data relatively, if the then tested terminal carrier meter reading of unanimity function is normal.
