Detection of operating conditions or no continuous and safe operation of the separator system possible. Especially with the separator system to be deposited problem substances such as light liquids such as oil, gasoline or fats, however, a reliable monitoring with reliable data is necessary. The separator systems are also usually buried in the ground or at remote sites available, which are decoupled from a necessary infrastructure for an appropriate infrastructure, which additional

CONFIRMATION SKOPJE Obstacles for safe operation of the separator system are overcome.

Especially against the background of ever higher

Environmental standards, which z. If, for example, the obligation to provide evidence required by law is linked to the operation of a separator system, a safe and complete monitoring of the operation of corresponding systems is inevitable in the future.

Purpose and advantages of the invention

The object of the present invention is to enable an improved operation of an arrangement of the type mentioned in the introduction.

This object is solved by the independent claims.

The dependent claims relate to advantageous variants of the invention.

The invention relates to a separator with a monitoring device for the separator comprising a separating vessel for the separation of liquid and / or solid constituents of a waste water flowing to the separator, wherein a treated in the separator plant part of the wastewater can flow from the separator, with a device for Acquisition of operating parameters in

Separation container, which generates operating signals, the cable from the separation vessel to an outside of the

Separation container existing transmitter unit are transferable.

A first essential aspect of the invention is that the monitoring device is designed such that a radio transmission of operating signals to a higher-level unit takes place with a packet-oriented radio service in a standardized mobile radio network or with a so-called GPRS service. The higher-level unit is advantageously connected to other units and can communicate with them

in particular by the usual means via the Internet,

for example, wired z. B telephone lines or

alternatively wirelessly or by radio.

GPRS stands for the English term "General Packet Radio Service". In a radio transmission with GPRS will

advantageously only at an actual

Data transmission occupied a radio room, otherwise the radio room is free for other users. In addition, the GPRS transmission is due to the package orientation and the

Standardization particularly advantageous. Advantageously, due to the multi-channel nature of the GPRS transmission, all relevant events in the separator system can be detected,

detained and z. B. be analyzed at a later date.

Thus, the monitoring of the separator system can be completed completely and in real time, with the separator system can be located at almost all possible sites. Advantageously, without major technical

Additional effort or relatively straightforward on an established and in many places already existing transmission technology

be resorted to. In comparison with previous ones

Procedures for monitoring the operation of

Separator plants, with z. B. manually guided

Operating manuals and all the disadvantages associated with this, result in the use of the GPRS service also a variety of completely new additional functions that can be used advantageously for the safe operation of the separator system.

With the proposed approach and with the

Radio transmission externally available data can not only an all-encompassing operating state and its

Documentation are provided, but in particular a 24/7 active warning device upon detection of critical situations during operation of the separator system to be established. It can advantageously several

different recipients, which receive information from the parent unit, in particular at the same time at an earliest possible date on a critical situation in the picture are set. In addition to the operator can also

Surveillance bodies such as authorities or ministries and / or affected bodies such as wastewater treatment plant operators or employment agencies such as fire brigades, police and / or technical aid organizations with corresponding detailed information

Information to be supplied.

Through the proposed transmission path and the integration into the packet-oriented radio service in a standardized mobile radio network, the handling of the data can be raised to a level in which all possibilities provided by electronic media can be used.

Advantageously, in addition to the data transmission from almost any location and over all relevant distances or up to almost all possible destinations worldwide, in particular the amount of data, the cycle time of the data acquisition or data query, data processing,

Data storage and / or data documentation can be determined almost arbitrarily in nature and scope.

Advantageously, relevant transmission and

Processing operations occur in near real time or in a timely manner or with the shortest transmission times. Furthermore, the procedure according to the invention is predominantly possible without personnel on site with low material use and low energy or current quantities at the location of the separator system or transmitter unit.

Preferably, the separator system is as

Light liquid separator system formed. A

Leichtflüssigkeitsabscheideranlage must due to the

Hazard due to improper leakage of light liquids contained therein, especially with regard to safe and reliable operation monitoring be advantageously equipped.

Another essential aspect of the invention is that the monitoring device is designed such that a transmission of operating signals to a higher-level unit takes place via an Internet connection. A transmission with an Internet connection is particularly easy and reliable to set up worldwide. The Internet connection can be wireless or wired, with various technical units can be used as a fixed

installed computer, a mobile computer or folding computer, a mobile phone or the like. Thus, a suitable monitoring device for the separator system can be provided variably.

It is further proposed that an intermediate unit is present, which receives the operating signals from the transmitting unit and with the packet-oriented radio service in one

standardized mobile network and / or via a

Internet connection to the parent unit transmits. This can from the transmitting unit, preferably in

Near range of the separation vessel is carried out to a remote over a particular middle area intermediate unit by radio transmission of the operating data. The

Sending unit transmits on a commonly selected simple radio transmission path or not in the GPRS service. Only from the intermediate unit, where usually a sufficient energy or power supply is available, what for the GPRS radio transmission. is necessary, is transmitted to the parent unit via GPRS radio transmission. The

Intermediate unit corresponds, so to speak, the sender side of the GPRS radio transmission, the parent unit of the

Receiver side of the GPRS radio transmission equals.

The arrangement according to the invention is particularly with regard to necessary measures z. B. at a location of

Separator plant in a relatively remote or difficult to access terrain advantageous. In particular, there is no connection for the connection from the transmitting unit to the intermediate unit structural measure required. The intermediate unit is preferably present in an easily accessible area, where a sufficient or secure power supply from a power grid or a 230 volt supply is provided, so that the intermediate unit for the GPRS radio operation, the necessary energy is available. The intermediate unit, for example a transmission module in a protected area such. B. a building, receives the transmitted by the transmitting unit operating signals and sends them by means of GPRS radio transmission to the

higher-level unit, in particular to a GPRS or an Internet or Web server on.

The data sent correspond in particular to the

Operating signals of the detection device or be

preferably only on the GPRS or Internet server processed z. B. evaluated. Depending on the information generated or obtained with the evaluation, it is then possible to trigger actions thereon or to activate operative functions. For example, an intended by the server via a particular Internet connection target unit, which includes, for example, a computer, a mobile phone or a landline phone, an audible and / or visual alarm or the like can be triggered.

Also an additional and / or other processing of

Operating signals, eg. B. a storage or graphical

Presentation usually takes place on the server, ie in particular not before the GPRS transmission. Thus, the transmitting unit, or if present, the intermediate unit

Accordingly less complex or operated with lower energy requirements, since these units in

Essentially, only the function of the data transmission, but not the processing and / or storage of the

Operating data.

The transmitting unit, possibly also the intermediate unit, can

be operated independently, for example, rechargeable batteries or batteries. The standardized mobile radio network preferably comprises a GSM and / or a UMTS network (GSM: Global System for Mobile

Communication, UMTS: Universal Mobile Telecommunications

System). Such standardized mobile radio networks are partly available worldwide via wide network extensions.

An advantageous modification of the invention is characterized in that the destination unit comprises a computer unit. Thus, with the destination unit, the obtained data can be effectively processed in various ways.

It is also preferable that the destination unit comprises a mobile phone. So can be available almost anywhere

Mobile phones serve as part of an information chain or are supplied with information. This can be Überwachungsbzw. Alerts almost to any place possibly also to mobile

Transmit receiver. About the mobile phone can

For example, facilities and persons of an operator of the separator, a service provider and / or an authority constantly with information about the operation of the

Separator system to be supplied. Thus, the elimination of problems in the operation of the separator system can be detected and significantly more effective and faster than before.

Alternatively or additionally, it is also advantageous that the destination unit comprises a telephone operated in a fixed network. This makes it possible in particular fixed target units

reach easily and reliably, as a rule

Landline telephones are available in relevant places.

It is particularly advantageous that the destination unit is connected to a monitoring point or with this

communicated. For example, in a control room or

a central computer of a monitoring station promptly or in real time and continuously a seamless monitoring of the separator system can be established. For example, the monitoring body may initiate necessary follow-up actions based on received information. The

Surveillance may, for example, an environmental authority municipal level and / or an environmental ministry at the state and / or federal level.

In this way, legislative requirements can be met or measures can be taken promptly and in the event of an emergency or problem situation

coordinated.

It is particularly advantageous that the separating container is buried. This is included

Liquid separator systems the rule.

Furthermore, it is advantageous that the device for detecting operating parameters in the separating container comprises a measuring probe. With probes such. B. Light liquid measuring probes or sludge probes can be very different

Operating parameters are detected particularly advantageous and technically secure.

It is also proposed that the device for detecting operating parameters in the separation tank a

Float arrangement includes. With a float arrangement, basic information can be recorded in the separation tank.

Finally, it is advantageous that the device for

Acquisition of operating parameters in the separation tank

is designed to trigger a warning signal, wherein

Control means are provided with which an on-the-spot control of the separation vessel is registered and available in the destination unit. So can all

especially after a critical process necessary or required by law to safely capture and register measures. This provides a proof function, so to speak. Furthermore, a gapless

Documentation in non-critical phases of operation or z. B. be set up in the manner of an online operating diary.

Moreover, the invention relates to a monitoring device for a separator system, in particular for a

Light liquid separator, with a device for detecting operating parameters of the separator system, which generates operating signals which are transferable from a separating vessel to a transmission unit present outside of the separating vessel.

The central idea is that the

Monitoring device is designed such that a transmission of operating signals to a higher-level unit with a packet-oriented radio service in one

standardized mobile network or with a so-called GPRS service and / or via an Internet connection. This can be the above-mentioned advantages even with a z. B. subsequently with the invention

Obtain monitoring device provided separator.

Advantageously, the intermediate unit is designed such that the transmission of operating signals to the higher-level unit takes place with a packet-oriented radio service in a standardized mobile radio network or with a so-called GPRS service and / or via an Internet connection.

In an advantageous variant of the invention

Monitoring device is that the intermediate unit is designed to receive operating signals from a plurality of different transmitting units, and the

Operating signals of the plurality of different ones

Send transmitting units to the parent unit.

The intermediate unit is also designed in particular via a radio service, whereby GPRS is excluded,

Operating signals of up to 250 different

To receive transmission units. In this case, the operating signals are assigned to each individual transmitting unit.

If appropriate, signals can be received simultaneously or in parallel from several transmission units.

The transmitting unit in turn receives the data or the Original operating signals wired by sensors of the

Separator plant over comparatively short distances z. B. in the decimeter range.

The intermediate unit receives the operating signals via z. B. a 2.4 GHz radio transmission or via W-LAN or another type of radio transmission, excluding GPRS. A signal transmission or forwarding from the intermediate unit to the higher-level unit takes place in packets via the GPRS service and / or via an Internet connection. In particular, the operating signals of up to 250 transmission units can be bundled and then sent to the higher-level unit or

for example, forwarding a server.

Advantageously, according to the invention, a laying of cables or lines between the intermediate unit and the sensors can be dispensed with. The wired transmission from

Separation container or the existing sensors there, however, is advantageous only over a relatively short

Distance up to the transmitting unit, which is positioned in particular adjacent to the separating vessel or in its vicinity.

This is also advantageous because, for example, connected to a separator system lines, for example, in a separation vessel to a washing place of z. As vehicles or refueling surfaces of vehicles or aircraft, can not be dug or only with great effort or this is not allowed. Therefore, a radio transmission from the transmitting unit to the intermediate unit is advantageous.

Another advantage is the fact that with a few or possibly exactly one intermediate unit, a plurality of

Transmitting units can be detected together, for example, transmission units of separator systems, via a

large area such. As an airport, a

Industrial or production plant distributed.

The parent unit, which is the intermediate unit with packetized signals may be positioned elsewhere, for example, in another city.

The invention is particularly against the background

advantageous that the radio transmission from the transmitting unit to the intermediate unit via a 2.4 GHz radio unit or z. B. via W-LAN. This comes with comparatively low

Voltages or amounts of electricity, which for example easily by batteries or rechargeable batteries for practical long

Operating times is possible. This is beneficial as the

Transmitting units or the separator systems are often away from or away from appropriate supply lines or infrastructure.

The transmission of operating signals coming from the plurality of different transmission units, further from the

Intermediate unit to the parent unit with the

packet-oriented radio service can be combined with a

Intermediate power supply network, for example, with 230 volts without problems permanently operated. Because the

Position of the intermediate unit is relatively free or in

Radio distance from the transmitting units selectable, wherein the

Intermediate unit is positionable so that a fixed

Power supply is available and thus the necessary for the GPRS transmission comparatively larger amounts of electricity are available.

In the higher-level unit or in further units connected to it, the data or operating signals can be evaluated and further processed, the data of the respective transmitting unit or its individual sensors

can be assigned.

In addition, corresponding assigned alarm signals can also be generated or triggered.

An advantageous variant of the invention

Monitoring device is characterized in that Conduction means are provided, with which the transmission of operating signals from the intermediate unit to the superordinated unit is wired or wired, in particular via an Internet connection.
