Specifically, anti-inspection apparatus design of visiting one house after another: it is contemplated that built-in public network communicates, a main slave, at one master and multiple slaves machine Mode;It is also contemplated that carrier schemes technology: carrier only solution technique;The communication of wireless carrier technology;It is also contemplated that 230M is logical News mode;Addition high frequency or low frequency electrical signal with directionality can be used in means, and both ends carry out detecting identification, then provides clear With loop signal or non-signal of going the same way;Power frequency circuit can also be used and determine ohmic load in user's most proximal segment external reinforcement, or be fixed Current loading carries out both ends and identifies simultaneously;Capacitive load or inductive load can also be added on low-voltage customer circuit, in this way may not be used Influence active total, more convenient checking loop;Using correspondence code mode, using table side and user side conventional load electric current as foundation, It carries out corresponding verification and compares differentiation consistency;The circuit on user entrance or user family's inner looping socket 26 are main loaded Position may be designed as 26 formula of socket and contact pin type;Using different communication modes, a time deviation should all be added from verification Logical program;It is specific when executing, a people at electricity box, another people on user entrance, equipment be added under table respectively outlet and At the terminal box of user doorway or in user family at socket 26, after synchronization time, start plus additional standard load, measuring resistance, Standard electric perhaps normalized current.
Specifically, additional load should have secondary or be confirmed above: can be designed by the maximum standard of electricity box, together At one electricity box, an equipment can tap 15 precision current transformers, one group of accurate voltage measure loop;It can disposably examine Survey an entire electricity box;Can table number, family number, room number first be arranged in host side in high-end designs, can input room number from generator terminal, centainly Just it can input room number at slave after wanting signal detection correct and then pass through the incoming host of communication signal and update main information, then Main information is printed Premium Features containing family number, room number, table number, user name etc.;Automatic identification, which should be arranged, electricity condition and nothing Electricity condition function, when no electricity, automatically switches to battery power supply and remind ray examination, for example to solve line and carry out to ray examination Etc. basic verification mode, additional low-voltage can also be started in the case where no alternating current, subscriber terminal side adds the side of standard termination Formula;It is contemplated that the mode of another cable loop payload size, possibility is lower because visit one house after another be usually all it is poor not More cable lengths;The mode that zero curve is shorted to ground wire, which is checked, visits one house after another, and principle is on condition that always open without earth leakage protective, zero line grounding Total zero curve can be returned to by zero curve and ground wire afterwards for line current, so the neutral line current at electricity box will appear variation, be changed with this Rate come embody whether the wiring under same family;The mode that user registers one's residence zero curve (in electricity box) and zero-emission is shorted, this mode can only Visiting one house after another within the scope of same electricity box is checked, can not be checked in the cable tube after electricity box, in channel, error connection within the walls;It can be with In conjunction with cell phone application software, the load precise figures that slave is measured with the standard time are transferred to backstage, and live meter reader is copied real-time Load also passes to backstage, and it is correct to be sent to meter reader confirmation for real-time core pair after correct;It is such the disadvantage is that user to zero power It can not verify, can not also verify uncharged.
Program profile: embodiment two including test host 2, test 3 two parts of terminal, constitutes slave exact p-value mould Formula.Scheme cardinal principle is in user side, and indoor installation tests terminal 3, mounting test host 2 at ammeter box, by detecting back Road voltage, current waveform carry out family table corresponding relationship and verify.Specific implementation are as follows: test terminal 3 inside has the controllable capacitive of switching Socket 26 in load insertion user man, tests host 2 monitoring voltage, current signal at electric energy meter.Test host 2 and test Terminal 3 carries out accurate clock synchronization, and terminal tests host 2 by whether can monitor estimated according to Host Command switching capacitive load Capacitive load currents waveform carry out judging family table corresponding relationship.
Specifically, research contents: originally visiting one house after another and verify instrument test 2 main research of host: high-speed high-accuracy voltage, electricity Flow acquisition scheme research;Test host 2 and test 3 precise synchronization clock synchronization Mechanism Study of terminal;Accurate voltage, galvanometer quantity algorithm Research;Originally it visits one house after another and verifies instrument test 3 main research of terminal: accurate capacitive load switching Mechanism Study;With test host 2 it Between long haul communication Mechanism Study, this verification instrument the key technical indexes to be reached: 0.2 grade of voltage, current precision, 41 subharmonic Measuring accuracy 1%;Identification distance is not less than 1000m;The communication interfaces such as GPRS/3G/4G, RS485, infrared, carrier wave built in host; Power consumption is less than 3.5W.
Specifically, project innovation and technological difficulties, the novelty of this programme is as follows: not consuming active electricity in detection process Can, do not have a power failure, avoids generating unnecessary dispute;Testing staff is indoor without entering, and user aid is only needed to insert terminal 3 is tested Entering on socket 26, reduces the embarrassment registered one's residence in family;Detection operating process is simple, and testing result is reliable.
Specifically, the technical problem underlying and solution of this programme are as follows: technical problem one: high-accuracy voltage current wave The acquisition of shape, this programme mainly judge family table relationship, this side by the regular capacitive low current of the detection test generation of terminal 3 The reliability of formula relies primarily on the order of accuarcy of waveform acquisition on site.Therefore, how to realize that high-precision fast signal recording is adopted Collection is an important technological problems for needing to solve.Using 0.1 grade of high-end advanced collection of simulant signal skill of gate energy meter Art, 24 bit AD sample chips+high-speed dsp processor 20 of high-speed, high precision is, it can be achieved that high-precision, the recording of rapid field waveform Acquisition.
Specifically, technical problem two: accurate voltage, current calculation method, it is generally the case that on non-electrical peak, big portion Divide user power utilization equipment and consumption habit more similar, detection is relatively easy.But in peak of power consumption, the load condition of user is poor It is different larger, if voltage, the electric current accuracy of measuring be not high to have an impact the correctness of testing result.Therefore, to acquisition signal High precision computation can directly determine the accuracy of testing result.Solution: at dynamic load metering, harmonic wave metering and critical point There is mature development Experience in terms of measurement meter, advanced metering algorithm can be used to solve the problems, such as this.
Specifically, anti-inspection apparatus design of visiting one house after another, it is contemplated that built-in public network communication, a main slave, at one master and multiple slaves machine Mode;It is also contemplated that carrier schemes technology: carrier only solution technique;The communication of wireless carrier technology;It is also contemplated that 230M is logical News mode, 230M are dedicated wireless uplink communication modes, are almost used less than in anti-detection of visiting one house after another.Band side can be used in means The addition high frequency or low frequency electrical signal of tropism, both ends carry out detecting identification, then provide clear with loop signal or non-letter of going the same way Number;High frequency or low frequency carrier signal directionality be not strong, if trap is not installed in ammeter side, the injected carrier at a certain user It may also detect that signal at other users under signal, same bus or same phase line, accurate detection can not be carried out.And pacify It is more complicated to fill trap operation, and has some potential safety problems, practicability is lower.It is nearest in user that power frequency circuit can also be used The additional fixed ohmic load of section, or be fixed current loading and carry out both ends while identifying, if it is constant resistance load, for convenient for Detection, power requirement is relatively large, and fever is corresponding more, and scene needs to consider heat dissipation problem when using;And use ohmic load It will increase the active consumption of user.It is identified it is recommended that capacitive load is added.
Specifically, can also on low-voltage customer circuit plus capacitive load or inductive load, can not influence in this way it is active total, More convenient checking loop, capacitive load are easy to produce and small in size, and when detection does not influence active total, facilitate operation, inductance is born Load is less susceptible to generate, and volume is very huge compared with capacitor under Same Efficieney, and than cumbersome, and cost is higher, does not recommend to make With.
Specifically, using table side and user side conventional load electric current as foundation, carrying out corresponding verification ratio using correspondence code mode Compared with differentiation consistency;User side cable is hidden in wall under normal conditions, and detection user's total load wiring is complex, is needed Indoor distribution box etc. is opened, is implemented relatively difficult.
Specifically, the circuit on user entrance or user family's inner looping socket 26 are main loaded position, can design It is 26 formula of socket and contact pin type, it is generally the case that user entrance is all located in user family without terminal box, distribution box.It builds View detection load design is 26 formula of socket, safe and reliable, easy to operate.Using different communication modes, it is inclined that a time should all be added Difference checks logical program certainly;When specific execution, at electricity box, another people is added under table a people respectively in user entrance, equipment At outlet and user doorway terminal box or in user family at socket 26, after synchronization time, start plus additional standard load, mark Quasi- resistance, standard electric perhaps normalized current, detection load design is 26 formula of socket, safe and reliable, easy to operate.
Specifically, can be designed by the maximum standard of electricity box, at the same electricity box, an equipment can tap 15 Precision current transformer, one group of accurate voltage measure loop;An entire electricity box can disposably be detected;Most of the time flower when detection In addition of the user from equipment, at same electricity box, disposably accesses 15 current transformers and the raising of whole efficiency is made With little, and it is higher to do so equipment cost.Overall efficiency and cost, it is proposed that four circuits of detection.
Specifically, can table number, family number, room number first be arranged in host side in high-end designs, room number can be inputted from generator terminal, one Surely just it can input room number at slave after wanting signal detection correct and then pass through the incoming host of communication signal and update main information, so Main information is printed Premium Features containing family number, room number, table number, user name etc. afterwards.
Specifically, automatic identification, which should be arranged, an electricity condition and electroless state function, when no electricity, automatically switches to battery power supply Ray examination is reminded, for example to solve line and carry out to the basic verification mode such as ray examination, the city (comprehensively considering) Ye Kewu In the case where electricity, start additional low-voltage, subscriber terminal side adds the mode of standard termination, can be by adding in the case where there is electricity condition Enter capacitive load, test voltage current waveform is detected.
Specifically, in the power-off state, device battery does not work for capacity load, table side can only be disconnected and be spaced apart, benefit It is verified with carrier-current signaling channel method.It is contemplated that the mode of another cable loop payload size, possibility is lower, because It is all usually more much the same cable length for what is visited one house after another;The mode that zero curve is shorted to ground wire, which is checked, visits one house after another, principle on condition that It always opens without earth leakage protective, total zero curve can be returned to by zero curve and ground wire for line current after zero line grounding, so zero at electricity box Line current will appear variation, with this change rate come embody whether the wiring under same family.
The zero curve specifically, user registers one's residence, the interior mode being shorted with zero-emission of electricity box, this mode can only check same electricity box model Visiting one house after another in enclosing can not check in the cable tube after electricity box, in channel, error connection within the walls;It can be soft in conjunction with cell phone application Part, the load precise figures that slave is measured with the standard time are transferred to backstage, after the real-time load that live meter reader is copied also passes to It is correct to be sent to meter reader confirmation for platform, real-time core pair after correct;It is such the disadvantage is that can not verify the user of zero power, it is right It is uncharged also to verify;The ammeter load of meter reader copy reading is not real-time load, there is the biggish time difference, passes through comparison The method error of ammeter and the load data of indoor metering equipment is larger.Under normal conditions, user power utilization equipment and consumption habit More similar, the load data in non-electrical peak, each user family is not much different, and the result accuracy that the method obtains is not It is high.
Specifically, equipment is constituted, host: work is in batch meter side, measurement or the current electric parameter data of copy reading, feedback data To slave.Slave: work applies signal or characteristic load, the electric parameter data of receiving host in user side, and thenad machine transmits number According to.Palm machine: analyzing for human-computer interaction and data, marketing archive information verification, inquiry, field print test data.
