Comprehensive above-mentioned characteristic, we can provide the system that has similar signal intensity than the front to have wider electrical network signaling system.

Below in conjunction with street equipment the present invention is discussed, but the present invention has application widely.Form the simplest according to the present invention can be operated street equipment such as street lamp by a connection to service cable, and wherein above-mentioned cable is powered to lamp stand.Lamp stand provides support to luminescence unit that comprises a light source or luminaire.Opening or closing of the power supply control lamp of cable.

Electrical equipment can be a light source that is suitable for providing light.Frame can be a luminaire (luminescence unit).

As everyone knows, correctly illuminate a zone, need carry out certain detection and whether work so that determine street lamp in order to make street lamp.Common faults comprises that blown fuse or light source broken, and the former personnel that employ into team patrol a zone so that find inoperable street lamp (and then maintenance or report fault).Do not expect to carry out hand inspection in many cases.For example, the switching if a street lamp circulates between open mode and closed condition, so the workman may be when street lamp be opened process, do not notice that this street lamp has fault.

Some supervisory personnel may be not as imagining so crediblely, and declare under many situations at the walkaround inspection lamp stand, but in fact be not.The supervisory personnel's of team advantage is provided monitoring arrangement to have need not to reemploy into for light source.

So just allow luminescence unit to carry out monitoring street lamp from the personnel that monitor and can not reemploy into team.By providing monitoring arrangement at (rather than in Socket for lamp pole) on the luminescence unit, monitor unit can be transferred to the place that the saboteur can not touch safely.Compare with supervision or control module with discrete luminescence unit, it is to have reduced expense that another advantage of self-contained unit is provided.When new lamp stand was installed, masthead unit or luminaire must be installed on the vertical lamp stand, and the sands are running out that self-test device signaling luminaire is installed is in the time that a standard device is installed.Distribution work is identical.

In luminescence unit, local treating apparatus is from the monitoring arrangement received signal and send signal to remote unit respectively.Thereby itself can handle the signal of monitoring arrangement and need on quite long distance, not send all original, primary data.Like this, when it was handled, the signal of monitoring arrangement should rare conflict and is had less noise.And local treating apparatus can be only on some time, and is for example in office what when its local treating apparatus is not visited remote unit, perhaps with fixing interval, for example per hour or send its signal to remote unit every day.Local treating apparatus is poll remote unit and only send the data-signal (vice versa, remote unit can poll rack unit) of its processing when receiving the download signal of loopback periodically.Because local treating apparatus can processing signals and in this locality storage related data, static data for example is not so need local treating apparatus to carry out continuous poll.

Can make the local treating apparatus can be continuously or on preset time, monitor signal from monitoring arrangement.Similarly, remote unit can be continuously or receive signal from local treating apparatus on preset time.Local treating apparatus (or remote unit) is the relevant data that satisfy the signal of predetermined principle of storage only.Local treating apparatus can filter out some data and not send the information that relates to all monitoring arrangement signals to remote unit.For example, in lamp stand, in 30 minutes after the fault of most electric lights appears at and turns on light.Local treating apparatus (or remote unit) is register lamp bar unit properties data in the back one section preset time (for example 30 minutes) of turning on light only.Alternatively, perhaps as a supplement, local treating apparatus can monitor monitors device signal, but does not write down the data (forward direction sends to teleprocessing unit) of relevant monitoring arrangement signal, unless they exceed (or falling into) predetermined scope or numerical value.Alternatively, if signal exceeds (or falling into) predetermined scope or numerical value, teleprocessing unit can received signal but non-tracer signal.

For example, a lamp stand has normal duty.Monitoring arrangement can be set to be made it to ignore and is in normal level or the signal in the permissible variation scope of " normally " state.If monitoring arrangement is checked concrete ohmically voltage in the lamp stand, then may ignore for example signal of 5V ± 0.5V (20% tolerance limit) scope.If signal drops on outside the scope of a permission, then local treating apparatus record relates to the information of signal and in time sends signal to remote unit.Local treating apparatus can be set, make it need not wait for its normal poll time, just when receiving a unacceptable signal, when perhaps the sensing signal is not rub-out signal outside determining scope, get final product the poll remote unit.Local treating apparatus is preferably handled a plurality of monitoring arrangement signals of its reception, and according to these monitoring arrangement signals, local treating apparatus preferably transmits appropriate signal to remote unit.For example, local processing unit can receive and handle: a) signal of the voltage on point of indication; Or b) signal of the voltage on second point of indication; Or c) signal of the electric current on point of indication; Or d) signal of indicated temperature; Or e) signal of indicated pressure or any other parameter; Or f) indication is a) to f) the signal of combination in any.

Remote unit can be by user inquiring, preferably remote inquiry.

Local treating apparatus passes through the mains supply cable from the remote unit received signal.Local treating apparatus can be operated a control module so that controlling light source (when device is light source) between the opening and closing state.Can carry out this control according to signal along the descending transmission of mains supply cable.Local treating apparatus also can be along the mains supply cable to the remote unit backhaul signals.The advantage of doing like this be allow local treating apparatus to monitor the operation of light source and to the remote unit backhaul signals so that indication fault.Also having an advantage is that remote unit can send signal to local treating apparatus, and may control the operation of light source.

Up to the present, have realized that independently control/supervisory signal processing unit can be provided.Especially to be suitable for being installed in the street lamp pedestal, the form in other electric light bracing or strutting arrangement or the electric device provides control/supervision/signal processing unit.Then, this unit is readjusted so that adapt to the electric device of standard, for example street lamp.The application that such system is very suitable for readjusting, wherein standard control module (may on the pedestal of street lamp lamp stand) is replaced by new control/supervisory signal processing unit.

Light source can comprise an incandescent source, fluorescent light, SOX, SON, MN, or other light source.

In one embodiment, the present invention is placed on light source and local treating apparatus (with monitoring parts) in the independent unit, and this unit is a luminaire.In another embodiment, can be placed on local treating apparatus in the breaking units, for example disclosed in the patented claim GB 2 261116 before us.

Local treating apparatus or remote unit can monitor that light source is lighted: promptly just in the luminous time.The advantage of doing like this is to allow the company/entity of control luminescence unit to determine whether light source satisfied regulation before breaking down working time.

Local treating apparatus and remote unit also can be used to half-duplex operation.This can guarantee the data communication that happens suddenly.

Can monitor the electric current in the luminescence unit in several ways.The user can be provided with surveillance style.A kind of possible mode is to measure luminescence unit, comprises by a ballast resistor total current of the electric current of capacitor and light source.The advantage that the user can be provided with characteristic has provided and can satisfy the equipment of various user's requests flexibly.

Remote unit and local treating apparatus can be used to be modulated on the carrier frequency near 135kHz appearing at signal on the mains supply cable.This frequency can be one relatively to the frequency of insensitive for noise.

Remote unit and local treating apparatus can be introduced phaselocked loop (PLL), and this phaselocked loop guarantees that system can " lock " on carrier frequency.

The problem that we run into when setting up long cable is to have voltage drop on the mains supply cable.This voltage drop has ill effect to reliable communication, and provides PLL can overcome this problem.

Can provide a storage arrangement for remote unit.Storage arrangement can write down the signal that sends to remote unit from local treating apparatus.The advantage of doing like this is to set up the operation historical record of luminescence unit (perhaps other electrical equipment when the present invention being applied to be different from other device of luminescence unit), wherein can retrieve this record and how work so that check luminaire.

Now by example and embodiment of the invention will be described with reference to drawings, wherein:

Fig. 1 has illustrated an operated system that monitors and control a plurality of street lamps from structure;

Fig. 2 has illustrated the carrier signal with the frequency that is much higher than noise from structure;

Fig. 3 has illustrated microcontroller of encapsulation and electronic circuitry involved from structure, and has the polymkeric substance module of a demountable identification code key;

Fig. 4 understands the identification code key of Fig. 3 in more detail;

Fig. 5 has illustrated a surveillance;

Fig. 6 has illustrated the structure based on a luminescence unit of the present invention;

Fig. 7 has illustrated the isometric view of a stand arrangement that is applicable to street lamp;

Fig. 8 has illustrated the detailed view of a remote unit 3.

Fig. 1 has illustrated the planimetric map of an optimum embodiment of the surveillance that is used for luminescence unit.This system comprises a main control unit 2 that links to each other with one or more remote unit 3.Each remote unit is controlled the operation of one or more street lamp 4,5,6.Each street lamp comprises 7,8,9 and stand arrangement 10,11,12 of a lamp stand (luminaire is made in common name).Mains supply cable 1 is a street lamp 4,5, and 6 provide electric power.

In Fig. 7, understand stand arrangement 10,11,12 in more detail.Stand arrangement comprises light source 13 and relevant 14, one monitoring arrangements 15 of starter circuit and control device 16.A local treating apparatus 17 also is provided.Stand arrangement 10,11,12 comprise the necessary device that all drive the light source that is comprised.Monitoring arrangement 15 comprises a plurality of sensors.Fig. 8 has illustrated the general view of a common stand arrangement 10.

In use, remote unit 3 sends enabling signal by mains supply line 1 to local treating apparatus 17.Local treating apparatus 17 in the stand arrangement receives this signal.Follow local treating apparatus and open and wait for predetermined one-period, after opening, perhaps need three minutes could be to remote unit 3 backhaul signals so that write down its operation or state.Like this, when a remote unit 3 linked to each other with a plurality of street lamps 4,5,6, remote unit can receive a series of status signal.Only store the signal of those indication fault situations at the storer (not shown) of remote unit, i.e. record trouble/error signal.Also time of recorder fault-signal, and record is which street lamp has been submitted this fault-signal to.

After answer signal is sent to remote unit 3, the instruction of local treating apparatus 17 products for further on the street lamp.At this moment street lamp 4,5, and 6 do not open yet.

Remote unit 3 can comprise a measurement need open street lamp 4,5, the photovoltaic element of 6 time, and perhaps alternatively, the control signal decision that can use master controller 5 to submit to need be opened street lamp 4,5,6 time.In these cases, when needs were opened street lamp, the local treating apparatus of remote unit 3 on each street lamp 4,5,6 provided a light source 13 " to open " signal.Sequential control is opened to avoid producing big spiking.Local treating apparatus 17 and control device 16 on each street lamp 4,5,6 then can be turned on electric light.Permission is through a predetermined period, and for example 10 minutes so that allow light source 13 to be preheating to its correct working temperature.In case pass by during this period of time, the local treating apparatus 17 on each street lamp 4,5,6 is then by mains supply cable 1 backhaul signals.The processing parameter signal that produces according to monitoring arrangement 15 obtains signal.Monitoring arrangement 15 is suitable for measuring the actual physical state of electric light.For example, monitoring arrangement 15 can comprise the sensor of measuring lamp current and lamp voltage.

In case light source 13 is opened, and reach balance (being that parameter does not fluctuate basically), then local treating apparatus 17 when certain parameter changes to signal of remote unit 3 loopbacks.Can indicate at street lamp 4,5 fault that takes place on 6 like this.

Stand arrangement also can be introduced the device (perhaps being control device) of control light source output.Then between full output state and weak output state, switch according to the signal controlling light source 13 that sends to local treating apparatus 17 from remote unit 3.As an example, can turn down brightness and make output current reduce 50%, thereby save 35% energy.When a large amount of street lamp is provided, can significantly save electric power like this.For example we wish to turn down brightness after midnight (for example 1:00am).

Because each street lamp 4,5,6 by remote unit 3 controls, can be turned down the brightness of one or more street lamp 4,5,6 respectively selectively, perhaps closes some street lamp selectively.

The advantage of above-mentioned Optimizing Control System unit is that this unit is event driven.Have only and when a signal is error signal, just be sent back to remote unit and note.An interested concrete condition is to switch between the opening and closing state continuously at a street lamp 4,5,6.When at street lamp 4,5, when having fault in 6 this situation can appear.In this case, can make the local treating apparatus monitoring failure signal in the frame, if and occur fault-signal at the fixed time in the section more than specified quantity, local treating apparatus 17 can send an error signal and cut out that street lamp that breaks down 4 to remote unit 3,5,6, be repaired up to it.

The signal that is transmitted back to remote unit 3 provides many possible improvement for the art methods that monitors street lamp.For example, local treating apparatus 17 can send a signal so that indicate the 13 actual times that open and close an of light source to remote unit 3.Follow the time quantum that recording light source 13 is opened, and can set up the accumulation total amount of " burning time " of expression light source 13.Have only and use the actual monitoring arrangement of opening time quantum of measurement light source 13 just can accomplish this point, this time quantum is different from the time quantum that indication light source 13 is opened.Obviously, the control device 16 in the stand arrangement can be opened light source 13, if but do not monitor whether light source 13 works, then can not correctly check " burning time " of light source 13 to check.

By monitoring the reality " burning time " of light source 13 before inefficacy, if light source 13 is not lighted correct hourage before breaking down, for example guarantee that electric light can continue 5000 hours but only continued 4000 hours, street lamp 4,5,6 service providers can require to return or complain.

Owing to independent street lamp 4,5,6 controls are provided, can provide one overtime (override) for each street lamp 4,5,6.For example, in order to satisfy safety standard, the street lamp 4,5,6 of main intersection and rotary island all must be lighted in free fully in institute.But, when the road utilization rate is low, wish to turn down street lamp 4,5,6 brightness is so that reduce energy consumption (for example in the late night to morning).Utilize this control method, remote unit 3 can be turned down street lamp 4,5,6 brightness (or closing), but still provide full electric power for some street lamp.

Stand arrangement also can comprise the

visual indication

18,19,20 with LED form.According to lighting LED18 from the output signal of the local treating apparatus 17 that has been provided stand arrangement, 19,20, perhaps can be controlled according to the distance sensor of stand arrangement.First LED18 shows that light source switch is opened, and a little less than second LED19 showed that light source is transferred, the 3rd LED20 showed that light source is opened fully.The maintainer can use LED18, and 19,20 determine whether operate as normal of street lamp 4,5,6.

Also can provide some diagnostic tools for this street lamp surveillance.Remote unit 3 can send a test signal to local treating apparatus 17, and local treating apparatus 17 also can be according to this test signal to status checking signal of remote unit 3 loopbacks.In this way, consistance that can check system.

The ability of measuring the virtual condition of street lamp 4,5,6 in real time provides several extra advantages.Because remote unit 3 can recorder and is write down time of signal, so efficient that can maintenance and inspection work.In an example, three street lamps 4,5,6 that form a line on the highway all break down, and then must keep in repair in two hours of fault generation.The level fault of Here it is so-called expression grave danger.After finishing maintenance, street lamp 4,5, the signals that the local treating apparatus 17 on 6 can worked to an indication of remote unit 3 loopbacks street lamp 4,5,6 now, and can recorder to time of this signal.Like this, can check in the correct time and finished repair.For example, under the situation that street lamp is opened, the work of electric light and general maintenance of replacing is contracted by street lamp service provider usually, and this system allows street lamp service provider can punish contractor under the unsatisfied situation of standard.

Also can between remote unit 3 or main control unit 2, provide a remote link.By a modulator-demodular unit can make an operator any time of its hope from any position, i.e. the data of the inquiry of the main control room on middle position record on remote unit 3.

Say that briefly we provide one to be used for street lamp 4,5,6 or the luminescence unit of supervision certainly of other appropriate device.Importantly, stand arrangement is self-contained, and introduces the monitoring arrangement 15 of itself.The parameter that this monitoring arrangement 15 is surveyed such as the luminescence unit curtage, and can survey the time of breaking down.Also can provide and realize complete required all control device 16 and the local treating apparatus 17 of long-range street lamp 4,5,6 surveillances, this system is suitable for carrying out remote inquiry by mains supply cable 1.Separating like that with the past provides frame to compare with processing/control module, and native system has been saved expense.And this system provides and has been easy to install and than the more survivable characteristic of prior art systems.The system of permission telemonitoring street lamp in the past be all lamp stands by frame good and prepare line after be installed in lamp stand 7,8,9 base portion.This is an independent operation, and does not resemble a lamp stand head and simply be installed on bar hole or the column so attractive.

The another kind of possible mode of the present invention for the treatment of provides a rack unit or luminaire, and this unit can be used to relatively easily provide (can be monitored) street equipment.

For the service part of street equipment is provided, the user has been provided the unit that only need install and be connected to supply lines with suitable method.

For example, if the parts of street equipment are street lamps, then can provide a luminaire that only need be connected to a lamp stand and be connected to supply lines for the user.

Can in shown in Figure 3 one independent module 21, provide monitoring arrangement 15, control device 16 and local treating apparatus 17.Each module 21 includes 20, one relevant converter circuits 31 of a microcontroller and a marker circuit 32 that is embedded in the epoxy resin module 33.A plurality of input pickup S1, S2, S3 monitors the appropriate physical characteristics of electronic circuit in the lamp stand, and for example S1 can monitor the voltage of certain point, and S2 can monitor the electric current of certain point, and S3 can monitor the voltage on another aspect, or the like.Sensor S1, S2, S3 is measuring-signal S1 respectively, S2, S3.

Microcontroller 30 is custom-designed commercial microcontrollers, also has other purposes the lamp stand except being used to monitor.But we can make microcontroller 30 obtain input signal S1 by suitable selection change-over circuit 31, S2, S3 and it is monitored that these signals are not those signals that are assigned to monitor at first.

Microcontroller 30 along supply lines to itself report signal of remote unit 3 loopbacks.Microcontroller has a storer (not shown) and can be programmed by remote unit 3 so that report in the mode of expectation.For example, in this specific embodiment, 3 pairs of microcontrollers of remote unit programme in case microcontroller in preceding 30 minutes of lamp stand work with the situation of interval tracer signal S1 to S3 in its storer of 5 seconds, and then stop to write down these signals (taking place) because we believe in most faults 30 minutes after electric light starts.Microcontroller is followed poll remote unit 3 so that request allows the download content in its storer to remote unit 3.If remote unit 3 finds not have other signal transmission, then microcontroller 30 sends a carrier signal on such as the 135kHz frequency of (as shown in Figure 2), and it is obtained the date is sent to remote unit 3.

Microcontroller 30 is by comprising an identification code so that identify itself in sending data.

Identification code is produced by marker circuit 32, and depends on the configuration of yard key 34.

As shown in Figure 3, a sign indicating number key 34 can take out and have 16 pins (8 pairs) from resin module 33, and these pins are inserted on the complimentary aperture 36 in the resin module.Understand sign indicating number key 34 among Fig. 4 in more detail, sign indicating number key 34 has 8 grooves 37 at its back and so that allow thin instrument is inserted in the groove 37.What be in encoding state not at first in groove 37 back is the circuit 38 that connects at 35.Thereby insert certain suitable tools disconnection or the continuous fixed circuit of katal by groove 37, can encode sign indicating number key 34.In Fig. 4 from top, open-circuit line 4,5,6, reserved

line

1,2,3,4 and 8 is motionless, thereby provide a binary coding (having 8 in this example) for sign indicating number key 34.Each local treating apparatus itself has independent, unique sign indicating number key.Be appreciated that we can handle 255 unit in an independent semiconductor by 8 keys.Simple increase two or more positions and just can be upgraded to 1000 or more unit easily.The circuit on disconnecting the sign key, all right operating switch of user is so that a given sign.

Be appreciated that yard key only has hardware and connects, and need do not programme to the sign indicating number key in mounting points.

Remote unit 3 is also to street lamp 4,5, and the independent local treating apparatus 17 in 6 is programmed so that hold the record all signals outside allowed band.Although in preceding 30 minutes, be certain to tracer signal S1 to S3 in the storer of microcontroller 30, and record (certainly so) no longer after this, but still to microcontroller programming so that the watch-keeping signal (for example with 5 seconds interval) and the signal outside the error range that allows of holding the record.Microcontroller 30 also can be configured to periodically, perhaps sends this unusual signal (when poll receives the instruction of proceeding) to remote unit 3 more in time.

Be appreciated that, remote unit 3 can be used to change the operation behavior of microcontroller 30, for example main control unit 2 can be used to tell remote unit 3 that per 5 seconds signal sampling period are once changed over per 10 seconds once, and perhaps per second is 10 times, perhaps any other cycle.Similarly, can change the initial record cycle.

Be appreciated that microcontroller can be programmed by main control unit 2 simply and then independently be monitored/report because microcontroller is a kind of strong instrument.Owing to carry out such processing in local treating apparatus 17, the working transmission that arrives remote unit 3 and main control unit 2 is very low, and has avoided the conflict between the signal.

A benefit that is appreciated that native system is that each module 33 is identical (perhaps basic identical) with microcontroller 30.This means that we can in a large number production module 33 and use some easily and preserve.If a module 33 existing problems are arranged, then the slip-stick artist can take out a substitute from the module of preserving, and to problematic lamp stand there (remote unit 3 is detected, and main control unit 2 inquires).Then he can dial down sign indicating number key 34 simply, pulls down the base unit of resin module 33 and changes new base unit resin module 33 into, more identical sign indicating number key 34 is connected on the new resin module 33.Can guarantee that so new resin module produces identical id signal (owing to producing id signal according to the configuration of sign indicating number key 34) and remote unit 3 can be mapped input signal and a concrete lamp stand.Carry out special programming with regard to not needing to replacing chip like this, and reduced and safeguarded the paralysis time of being caused.

In the zone of specific question is arranged, for example at contiguous iron tower, have in the zone of many interference, we can use special add-on module to strengthen the specialized performance of normal resin module 33.For example, we can use a slip-on filter unit to improve noise filtering.This wave filter can be inserted in the particular port of resin module, perhaps can couple together in position with circuit, wherein provides particular port in all resin modules.

Similarly, in the distance of the parts of the street equipment that is monitored and remote unit 3 zone far away, we can comprise a supercharger unit with as independent add-on assemble.

Fig. 2 is that another characteristic has been described from structure also.Remote unit 3 can be to microcontroller programming so that adjust the frequency of its carrier signal 40 in a scope.Scope shown in Figure 2 is 90kHz to 145kHz.In all cases, the frequency of carrier signal exceeds the main frequency of noise.Although some noise occurs in frequency range 90kHz to 145kHz, following meeting discussion overcomes the method for these noises.

Opposite with microprocessor, using an advantage of microcontroller is that we can have stronger instrument in less relatively space.For example, we can have the resin module 33 that is of a size of 100 millimeters X55 millimeter X40 millimeters.This module is sufficiently little so that can be installed in the standard rack of street lamp light source.

Communication link 66 between two

buffer zones

68 and 70 is half-duplex links on the mains supply line.Pass in and out computing machine 62 along link 66 by the phaselocked loop carrier wave transmission information that guarantees data consistency.Opposite with the 40Hz to 60Hz in the electrical network, can on the frequency band of 90kHz to 145kHz, send.In order further to guarantee data consistency, in the software of computing machine 62, introduce an automatic error correcting routine so that replace any information bit of loss.Communication stream between the

buffer zone

68 and 70 can have digital form or any other suitable form.

For monitor 64 provides one independently to power 76, it can be the electric network source that is different from the electric network source that link 66 is provided.

Transmit the information of the operation that relates to a part of street equipment by a plurality of analog inputs to microcontroller 72.We recommend that 8 analog inputs are arranged, although four

analog inputs

78,80,82 and 84 only are shown among Fig. 6.For each

input

78,80,82,84 provides a signal conditioner 86 and an optoisolator 88.Input can comprise the signal that relates to AC signal (for example electric network source), a direct current signal, other current signal, or expression absolute temperature or temperature variation, for example signal of atmospheric temperature or temperature variation.Signal conditioner 86 is suitable in the scope that microcontroller 72 receives conditioning signal in proportion at one.This scope can be 0-5V.Optoisolator 88 is occurring can providing potential partition under the situation of signal that surge or other can injure microcontroller 72.

Microcontroller 72 has three outputs at least.Show three

outputs

90,92 and 94 in the drawings.These outputs can be to use for outside, have the output of any volt, and the external loading power supply of electric light (for example to) is simulated the pulse-length modulation output of control or the output of standard analog direct current volt.

Can provide a plurality of input/output end ports that carry out required supervision and control for microcontroller.In this embodiment, can use two 8 bit ports that constitute 16 signal input/output end ports.

As mentioned above, the present invention is not limited only to monitor the field of street equipment.The present invention can be used as at the measurement of the electrical equipment of different range or device or control system.

Other technical characteristic of being worth mentioning of electrical network signaling system has:

In module 21, provide two LED100,101.Two LED all notify the information of the communications status of subscriber-related module 21.

LED100 is identified into RX/TX and indicating module 21 " is intercepted " mains supply cable 1 at correct carrier frequency (135KHZ).In common use,, glimmer so the LED100 meeting is frequent because electric network noise/spiking (being generally the microsecond level) can often and momently mate with the carrier frequency of 135KHZ.At this moment, although module 21 has been found that correct frequency, before responding, local treating apparatus 17 must satisfy a plurality of parameters.

Before LED101 (carrier wave is accepted LED) lighted with indication carrier wave receive status and the 21 reception orders of permission module, the 135KHZ carrier frequency must occur 100 milliseconds.Can send these 100 milliseconds of time delays and stop 21 pairs of electric network noise/spikings that prolong in short-term of module from remote unit 3 and respond by same frequency.

When receiving suitable carrier frequency when (surpassing 100 milliseconds 135KHZ), module 21 is opened command channel and is prepared to receive data.These data must be from the correct address (being provided with by sign indicating number key 34) of module 21, and then data must comprise proper A SC II character (digital 0-9 and capitalization A-Z).If these conditions do not satisfy, then the unit can stop its data buffer and 0 state that turns back to so that restart.

If all messaging parameters all are satisfied, then module 21 can respond to remote unit 3 orders.

A photoelectric detector can be provided whether open so that determine the door of Socket for lamp pole part.Obviously these doors should be closed when using electric light, and must know whether that careless not pass is to the doorstep so that can close.

Can not carry out the communication between remote unit 3 and the module 21 continuously, send but can be used as burst to message.

Correct ASC II character in the data that remote unit 3 (passing through software) inspection (three times) receives, and whether a filter 23 message is so that constitute a correct demonstration string and a data recording, for example because a circuit noise/spiking of not expecting is damaged first data-message.To the communication of handling device 17, also carrying out this inspection from remote unit 3.

S:000?B:00000:00:00?CH0:@&CH1:000?CH2:000?L:U/C/O

Then, because the mistiming, second message can be-

S:000?B:@&00:00:00?CH0:000?CH1:000?CH2:000?L:U/C/O

And the 3rd message can be-

S:000 B:00000:00 CH0:000 CH1:000 CH2:0@﹠amp; L:U/C/O@﹠amp;=error character

Remote unit 3 takes out wrong ASC II character and filters out 3 message so that read proper messages-S:000 B:00000:00:00 CH0:000 CH1:000 CH2:000 L:U/C/O

This characteristic is important in the very big environment of noise, and verified extremely successful, has not had the equipment (clock or the like) that other can operate as normal because often be.

Have Management Information Base, wherein some order is the global command of all modules 21 of communicating by letter with remote unit 3 of control, and other orders are special independent orders at the module 21 of communicating by letter with remote unit 3.
