This application is a national stage application of International Patent Application PCT/EP2019/083087, filed on Nov. 29, 2019, which claims priority to Germany Patent Application No. 202018106834.2, filed on Nov. 30, 2018, each of which are hereby incorporated by reference in their entireties.
The invention relates to a mobile sanitary device, in particular for a rail vehicle, comprising a vacuum toilet, a flush button, a power supply, a control device and a control unit. Furthermore, the invention relates to a control unit for a mobile sanitary device, in particular for a mobile sanitary device in a rail vehicle. Furthermore, the invention relates to a method for configuring a mobile sanitary device, in particular a mobile sanitary device for a rail vehicle and to a method for controlling a mobile sanitary device, in particular a mobile sanitary device for a rail vehicle.
Mobile sanitary devices with control units of the type described above are used on board of vehicles, for example track-bound vehicles, in particular rail vehicles, buses, airplanes or watercraft, and in the sense of this description and the claims this shall be described by the term “mobile”.
Conventional sanitary facilities in which both the fresh water or flushing water supply and the wastewater discharge are carried out gravitationally, i.e. by gravity alone, are not possible in numerous applications on board of vehicles due to constructional and spatial restrictions. It is therefore common practice to perform fresh and rinse water supply and wastewater discharge by means of an active drive, which is usually controlled by a control device. Such a control device is usually coupled with the components of the mobile sanitary equipment by means of a control unit. In addition to the structural and design advantages, this can also accelerate the water supply and water discharge, resulting in better overall hygiene and functionality of the sanitary facility.
The installation of mobile sanitary equipment on board of vehicles, especially rail-bound vehicles, is complex. As a rule, a mobile sanitary unit is an individual product, with each mobile sanitary unit requiring an individual configuration of the individual components and/or assemblies.
This is due, among other things, to different installation conditions in different vehicles. The complexity is further increased by the fact that divergent requirements can be placed on mobile sanitary equipment. Due to this high complexity and individuality of the mobile sanitary facilities to be installed, a high complexity in development and production can also be observed at manufacturers of mobile sanitary facilities. One of the reasons for this is that the individuality of the product means that few standards can be used, so that many individual parts of the mobile sanitary equipment are tailored to or configured for a specific project. This results in high costs in development and production. The individuality of the mobile sanitary equipment also increases the probability of errors, which results in high control costs. This is particularly high in the case of mobile sanitary facilities, since mobile sanitary facilities must be characterized by a particularly robust and error-free design.
Mobile sanitary equipment is usually controlled by a control device. The control device can, for example, control a vacuum pump of the vacuum toilet. A control unit, also known as a control panel, regularly acts as an interface between a control device and the components of a mobile sanitary facility. Basically, there are two different ways to configure such a control unit. One way of constructing such control units is the clamping technique. Here, the control unit usually comprises a large number of individual clamping terminals, with each individual terminal being configured. One advantage of control units constructed using such clamping terminal technology is that they are highly flexible. Thus, a wide variety of devices of the mobile sanitary unit can be coupled to the control unit. A disadvantage of such a control unit constructed with clamping terminal technology is that this is time-consuming in production and consequently cost-intensive.
Another way to build control units is to provide a circuit board, e.g. a printed circuit board (PCB). A printed circuit board has an internal circuit. Predefined functions can be implemented on a printed circuit board. A printed circuit board is in particular a carrier for electronic components and comprises conductor tracks which act as conductive connections. The advantage of printed circuit boards is in particular that they can be provided as a standard component.
As a standard product, the printed circuit board can always be printed in the same way and equipped with electronic components. However, printed circuit boards are not usually characterized by a high degree of flexibility.
As a rule, printed circuit boards are provided on such products that have a high quantity and a low configuration variance. Short-term changes or changes in the circuitry lead to a high modification effort. This modification effort consists of high one-off costs and in addition, long modification times are required.
In the development and production of mobile sanitary equipment, a decision must therefore be made in each case as to whether the flexible but costly clamping technology should be used or the essentially non-flexible but low-cost printed circuit board for large quantities is used. However, this always leads to compromises in terms of flexibility and cost.
Vehicles are generally designed in such a way that they have a high passenger transport capacity. In particular, as much seating and/or standing space as possible is provided. When designing vehicles, therefore, an attempt is made to provide the traffic routes and sanitary facilities as space-saving as possible. Mobile sanitary facilities must therefore be designed to save as much space as possible. In particular, it is necessary for the individual components of the mobile sanitary facility to have a compact design.
It is therefore a task of the invention to provide a mobile sanitary device, a control unit for a mobile sanitary device, a method for configuring a mobile sanitary device and a method for controlling a mobile sanitary device, which reduce or eliminate one or more of the aforementioned disadvantages. In particular, it is an object of the present invention to provide a solution that enables flexible and cost-effective development and manufacture of mobile sanitation devices. Furthermore, it is an object of the invention to provide a mobile sanitary device that is as space-saving as possible.
According to a first aspect, this task is solved by a mobile sanitary device, in particular for a rail vehicle, comprising a vacuum toilet, a flush button, a power supply, a control device and a control unit, wherein the control unit comprises: a standard circuit board for routing predefined signals, having a standard interface comprising a vacuum toilet connection means for connecting a vacuum toilet, a flush button connection means for connecting a flush button, and a voltage supply connection means for connecting a voltage supply, a configuration circuit board for routing signals, having a configuration interface with a first configuration connection means, wherein the vacuum toilet connection means, the flush button connection means, the voltage supply connection means and the first configuration connection means are conductively coupled to one another, wherein the configuration interface is set up such that the configuration circuit board is coupled to the control device, and at least one signal carried by the standard circuit board and/or by the configuration circuit board can be tapped, processed and/or driven by the control device.
(Printed) circuit boards are also referred to as cards. The standard circuit board and/or the configuration circuit board is preferably designed as a printed circuit board. The standard circuit board and/or the configuration circuit board preferably comprises or includes an electrically insulating material. Furthermore, conductive connections, the so-called conductor tracks, are preferably arranged on this material. The electrically insulating material of the standard circuit board and/or the configuration circuit board can, for example, be a fiber-reinforced plastic or a hard paper.
The standard circuit board includes the standard interface. The standard interface comprises at least the vacuum toilet connection means, the flush button connection means and the voltage supply connection means. The vacuum toilet connection means is arranged such that a vacuum toilet can be connected to the standard circuit board by means of it. By connecting the vacuum toilet to the vacuum toilet connecting means in this way, it is possible to connect the vacuum toilet to the control unit. Further, a signal sent to the control device can thus be routed to the vacuum toilet via the vacuum toilet connection means and a suitable line between the vacuum toilet connection means and the vacuum toilet. Such a control signal may, for example, control a vacuum pump or a compressed air valve of the vacuum toilet.
The flush button connection means is set up to connect the flush button of the mobile sanitary unit to the standard circuit board. The standard circuit board is preferably set up to transmit a flush button signal to the vacuum toilet in such a way that the flush signal causes a flushing process there. This flushing signal can be sent by the control device, for example.
Furthermore, the standard interface of the standard circuit board comprises the voltage supply connection means, which is arranged for connecting a voltage supply. Preferably, the voltage supply connection means is coupled to a voltage transformer. The voltage transformer is preferably arranged on the control unit.
Furthermore, the standard circuit board is preferably set up in such a way that only a vacuum toilet, a flush button and a power supply can be connected to the standard interface. The connection means of the standard interface are preferably designed as plug connections. In particular, it is preferred that the connection means of the standard interface are provided as standardized connection means. The plug connection can be designed as a male connector, for example.
The configuration interface with the first configuration connection means on the configuration circuit board is characterized by a high connection flexibility. The configuration interface with the first configuration connection means is set up to tap, process and/or control at least one signal carried by the standard circuit board and/or the configuration circuit board by the control device. In this way, the configuration interface can be used to intervene in the signal path of the standard circuit board.
In particular, the possibility that a signal carried by the standard printed circuit board and/or the configuration printed circuit board is controlled by the control device provides the possibility of individual signal manipulation. In particular, it is preferred that two or more signals carried by the standard circuit board and/or configuration circuit board are controllable, controllable and/or processable via the configuration interface. It is further preferred that two or more signals carried by the standard circuit board and/or the configuration circuit board are controllable by the control device. Furthermore, it is preferred that any signals carried by the standard circuit board and/or the configuration circuit board are controllable, processable and/or controllable.
The vacuum toilet connection means, the flush button connection means and the voltage supply connection means as well as the first configuration connection means are preferably conductively coupled to a cable harness and can thus be connected to further components. The wiring harness preferably comprises female connectors, which may be of double-row design, for example. As a result, components of a mobile sanitary device, such as vacuum toilet, flush button and/or power supply, can be connected to the control unit and signals can be transmitted. Furthermore, signals can be transmitted from the control device to components of the mobile sanitary device via the standard printed circuit board and the connection means mentioned in the foregoing.
The control unit described in the foregoing is based, among other things, on the realization that mobile sanitary facilities generally have an intersection of functionalities that are always the same. These functionalities can be implemented on the standard circuit board. Due to the standard interfaces with the vacuum toilet connection means, the flush button connection means and the voltage supply connection means, it is possible to connect the components to be connected to it with a standard connector.
The control unit is further based on the realization that this standard configuration for the standard functions can be individually extended by means of a configuration interface. In particular, the flexibility of the control unit is increased by the possibility of tapping, processing or controlling signals carried by the standard circuit board and/or the configuration circuit board. Due to a control unit as described in the foregoing, two target values that have been previously impossible or difficult to combine in the field of control units for mobile sanitary equipment, namely a high degree of standardization and a high degree of flexibility, can be combined.
The control unit described enables the extensive use of standard components. The control unit can be used as a standard component in a wide range of individually configured mobile sanitary equipment. The control unit thus offers the efficiency explained at the beginning by means of the standard circuit board, which in the past, however, restricted flexibility too much. However, the configuration PCB now makes it possible to increase the flexibility of the control unit. This flexibility, which was achieved in the past through the terminal strip technology, can now be achieved through the configuration interface. The control unit, in conjunction with a wiring harness, preferably makes it possible to dispense with any terminal technology and single-wire wiring in assembly. Consequently, assembly is reduced to installing the modules and plugging in the wiring harness. Furthermore, the control unit enables a standardized base plate on which the control unit can additionally be arranged. The interfaces further enable a standardized configuration matrix of different, predefined cables that vary only in length. Furthermore, due to the standardized control unit, test stands can be simplified and require less effort. Furthermore, the standardized control unit enables simplified processes in production, cost calculation and purchasing, since a minimum stock level can be defined for the standardized control unit.
In addition to the high degree of standardization, the invention was based on the realization that a compact design of the control unit is possible through a standard circuit board and a configuration circuit board. Conventional control units require a large amount of space due to the large number of terminals or the two-dimensional printed circuit board. The control unit described in the preceding makes it possible to arrange the two printed circuit boards in three dimensions, thus enabling a compact design of the control unit. The compact control unit allows the mobile sanitation device to be designed in a more space-saving manner. As a result, the mobile sanitary device takes up less space in a vehicle, which can increase the passenger transportation capacity.
In a preferred further embodiment of the mobile sanitary device, it is provided that the standard circuit board and the configuration circuit board are coupled to each other with a coupling means, wherein preferably the coupling means is formed as a flex connector. The coupling with the coupling means allows the standard circuit board and the configuration circuit board to be individually arranged on the control unit, in particular in a housing of the control unit. In particular, the standard circuit board and the configuration circuit board can be arranged in a space-saving manner to enable a compact design of the control unit.
Another preferred embodiment of the mobile sanitation device is characterized in that the control unit comprises a housing having a cavity, wherein the standard circuit board and the configuration circuit board are arranged in the cavity. Preferably, the planar extensions of the standard circuit board and the configuration circuit board include a circuit board angle with each other.

In particular, it is preferred that the standard printed circuit board and/or the configuration printed circuit board are each arranged spaced from an inner side of the housing by means of spacer elements, in particular sleeves. Fastening can be effected by means of fastening elements, for example by means of rivets extending through the sleeves.
