Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
See Fig. 2, electrostimulation plant described in the utility model removes the micro-current detecting safety guard of haze system and comprises current transformer 1, voltage sampling resistor R0, differential operational amplifier 2, proportional integral amplifier 3 and the several functional unit of overcurrent alarm and control device 4.
Current transformer 1 adopts model to be the miniature pulse current instrument transformer of TAK12-005, for sampling to micro-electric current of electrostimulation plant except the electric power loop in haze system.
Voltage sampling resistor R0 changes voltage quantities into for the current variable obtained of being sampled by current transformer 1.
Differential operational amplifier 2 is made up of (see Fig. 3) the operational amplifier A of first three in integrated circuit (IC) chip LM324 1, A2, A3, power taking stimulating plant removes haze intrasystem excitation power supply stimulating plant and amplifies with the voltage difference of non-stimulating plant, and the background operating current of the non-stimulating plant of excitation power supply deducted by this differential operational amplifier.
Proportional integral amplifier 3 by the most rear class operational amplifier A 4 in LM324, for carrying out further voltage amplification to its prime signal.
Overcurrent alarm and control device 4 is for generation of the overcurrent alarm and control signal when human body is near plant blade tip.In practical application structure, overcurrent alarm and control device 4 can adopt the small-sized single-chip microcomputer STC12C2052AD with A/D function, also can adopt voltage comparator LM393.
The circuit theory diagrams that the utility model is specifically implemented as shown in Figure 3.
The electrostimulation plant shown in Fig. 1 except in haze system, impedance load in the current circuit of its excitation power supply does not possess good conductive capability air dielectric, therefore the electric current of its current circuit is very little, therefore current sampling unit of the present utility model (current transformer 1) has selected a kind of miniature pulse current instrument transformer TAK12-005.The original grade coil of this current transformer 1 is with the electrostimulation plant shown in Fig. 1 except current detecting end in haze system is connected, and secondary coil also meets voltage sampling resistor R0, and current variable is converted to voltage quantities.
Due to human body near plant blade tip time load current increment very faint, need the utility model utilize differential operational amplifier circuit network to extract and amplify this weak voltage signals.Integrated circuit (IC) chip in Fig. 3 is LM324, and 3 operational amplifier A 1 in it, A2, A3 constitute a kind of differential operational amplifier.In order to deduct the background operating current that electrostimulation plant has at non-stimulating plant except the excitation power supply in haze system, the voltage stabilizing didoe D1 used in differential operational amplifier circuit network, by spacing for the current potential of the A2 in-phase end magnitude of voltage caused at voltage sampling resistor R0 two ends to excitation power supply background operating current, like this, differential operational amplifier only amplifies the voltage increment that stimulating plant causes at R0 two ends.Signal through differential amplification is exported by operational amplifier A 3, after the proportional integral of next stage proportional integral amplifier A4 amplifies, export an analog voltage signal V0.
Overhead many factors such as distance are relevant for the size of the micro-electric current obtained except current detecting end measurement in haze system due to electrostimulation plant and floristics, ambient temperature and humidity, blade tip, and therefore the size of V0 also can change because of the change of floristics and ambient temperature and humidity.In order to obtain security alarm and control signal by V0, this analog voltage signal can be input to the analog voltage signal input of the STC12C2052AD in overcurrent alarm and control device 4, the A/D converter of this analog signal in this chip is converted to digital voltage signal, program software reads each digital voltage signal by obtaining during the boost pulse of electrostimulation plant except output in haze system, and the digital voltage under current state and the start initial number voltage read that powers on is compared.When without human body proximity plant blade tip, the V0 value read during boost pulse is substantially identical, and when human body or its point closely plant time, V0 value will be significantly increased (V0+ △ V0), namely Contemporary Digital voltage is obviously greater than initial number voltage, program will according to the size starting protection subprogram of the two difference (△ V0), need to send visual alarm by the light-emitting diode of overcurrent alarm and control device 4 during safeguard protection, and output overcurrent control signal removes the power work control port of haze system to electrostimulation plant simultaneously, make electrostimulation plant except haze system stalls, thus reach the object avoiding human body to touch leaves of plants point electrostatic, after human body or its finger are again away from plant blade tip, electrostimulation plant removes haze system and returns to again normal operating state.
Although the size of V0 also can change because of floristics and ambient temperature and humidity, the △ V0 that program software measures is relative increment, and thus the alarm and control signal of overcurrent alarm and control device 4 is not subject to the impact of floristics and ambient temperature and humidity.
Overcurrent alarm and control device 4 also can adopt a voltage comparator LM393 to carry out practical function, it needs to carry out the security alarm threshold voltage of preset electrostimulation plant except haze system by a potentiometer, and the large I of preset threshold values security alarm voltage is removed haze system according to used electrostimulation plant and arranges the requirement of warning sensitivity.By voltage comparator LM393, V0 is compared with preset threshold voltage, when V0 is higher than preset threshold voltage, light-emitting diode sends security alarm signal, and controls the out-of-work control signal of power supply from voltage comparator output to electrostimulation plant except the power work control port of haze system exports.
This utility model device can implement safeguard protection when human body or its point about 2 ~ 3mm general close to plant blade tip.
