Embodiment
Below in conjunction with accompanying drawing, the present invention program is described in detail.
The high-voltage charge display device that the present embodiment provides, primarily of signal acquisition module, locking control circuit, main circuit, voltage display module and alarm module composition, see Fig. 1.Signal acquisition module, locking control circuit, voltage display module and alarm module communicate to connect with main circuit respectively.
Signal acquisition module forms primarily of filtering circuit, protection circuit, amplifying circuit and three phase.Three phase are connected with protection circuit, filtering circuit and amplifying circuit successively.
In the present embodiment, voltage display module is made up of buffer circuit and voltage display circuit.Buffer circuit is connected with voltage display circuit.
In the present embodiment, alarm module is made up of signal analysis and storage unit and ZigBee communication module.Signal analysis and storage unit communicate to connect with ZigBee communication module, main circuit respectively.
Signal analysis and storage unit are made up of memory storage and A/D Data collecting conversion circuit.A/D Data collecting conversion circuit is connected with main circuit and storage communication respectively.
Further, A/D Data collecting conversion circuit forms primarily of the first amplifier, the second amplifier, the 3rd amplifier, instrument amplifier, integrating capacitor, analog transmission device, four-way analog switch and voltage comparator.The input end of analog transmission device connects the reverse input end of instrument amplifier respectively, the input end of instrument amplifier connects the in-phase input end of the first amplifier, first amplifier output terminal be connected with the reverse input end of the second amplifier, one input end correspondence of four-way analog switch connects the output terminal of the second amplifier, another input end is by being connected with two output terminals of four-way analog switch, form discharge loop, the reverse input end of the 3rd amplifier is connected with two output terminals of four-way analog switch respectively, and output terminal is connected with integrating capacitor and voltage comparator respectively.Wherein, the model of instrument amplifier is AD624.First, second and the 3rd amplifier are the bipolar operational amplifier of the non-chopper-zero-stabilized of OP07.Four-way analog switch is the digital control analog switch of CD4052 difference four-way.Because the enlargement factor of operational amplifier is different, the offset error that the parameters such as its offset voltage cause is different.So first all amplify with same multiple reference voltage V i, the zero-point voltage Vo of input signal Vx and its correspondence in this change-over circuit, with the error avoiding offset voltage etc. to cause, thus improve conversion accuracy.The voltage follower that voltage signal Vo subsequently after amplifying process is consisted of amplifier OP07-1, be then input to the inverting input of amplifier OP07-2, the object adding voltage follower carries out impedance transformation.Amplifier OP07-2 forms totalizer, to realize the A/D conversion corresponding with offset binary code.First by counter O reset before A/D conversion starts.Under software, the X-tube pin of gating CD4052, forms discharge loop and integrating capacitor C is discharged completely, then starts A/D conversion.By controlling the gating to the different pin of CD4052, thus complete A/D conversion.Namely this A/D change-over circuit improves conversion accuracy and also improves switching rate.
AD624 is a high precision, low noise instrument amplifier, and major design is used for low level sensor, comprises load sensor, strainometer and pressure transducer.It melts low noise, high-gain precision, low gain temperature coefficient and high linearity in one, is suitable for high-resolution data acquisition system.
OP07 is the bipolar operational amplifier of a kind of low noise, non-chopper-zero-stabilized.Because OP07 has low-down input offset voltage (being 25 μ V to the maximum for OP07A), so OP07 does not need extra zeroing measure in a lot of application scenario.OP07 has input bias current low (OP07A is ± 2nA) and the feature of open-loop gain high (be 300V/mV for OP07A) simultaneously, and the characteristic of this low imbalance, high open-loop gain makes OP07 be specially adapted to the aspect such as the measuring equipment of high-gain and the feeble signal of amplification sensor.
CD4052 is a difference 4 passage numeral control simulation switch, has A, B two scale-of-two control input ends and INH input, has low conduction impedance and very low cut-off leakage current.Amplitude is that the digital signal of 4.5 ~ 20V can control the simulating signal of peak-to-peak value to 20V.
The high-voltage charge display device that the present embodiment provides adds remote wireless signals transfer function on original basis, carries out analyzing stored function to the signal monitored.In device, the original each functional circuit circuit of removing, has also increased alarm module newly.
Signal analysis and storage unit are to the fluctuation of signal exceeding certain limit, and being assessed as reports to the police occurs, and can read real-time clock, and sampled value and real-time clock are formed an alarm logging, be stored in storer.When control center's signal receiving end wants data by ZigBee net, alarm logging can take out by analyzing stored module from storer, passes to control center by ZigBee net.Control center, by analyzing real time data, reaches the object of monitoring consumer duty, if there is exception, can arrange the inspection of related personnel's line walking.So, this device not only can complete the display of abnormal signal and the latch-up protection of equipment, can also notify that managerial personnel carry out fault handling the very first time, helps managerial personnel's analyzing failure cause.
