The invention relates to a method for operating a work appliance or rescue appliance according to the preamble of claim 1, to a work appliance or rescue appliance according to the preamble of claim 15, and to a chargeable electrical energy source for such a work appliance or rescue appliance.
Portable, motor-driven work appliances or rescue appliances, of the type under consideration here, that can be carried by an operator are used in a multiplicity of applications. Thus, for example, there are cutting appliances, which are used by emergency services personnel (fire brigade) to rescue injured persons from vehicles involved in accidents or to free, for example, earthquake victims. The work appliances or rescue appliances in these cases vary greatly in type. There are electrohydraulically or electromechanically driven work appliances or rescue appliances having, preferably hardened, tool inserts for cutting, spreading or lifting. When in use, such appliances are subjected to extremely high mechanical demands and, depending on the place of use, are exposed to a very great variety of environmental influences (heat, cold, humidity).
At the same time, it is particularly important that rescue appliances, in particular, afford a particularly high degree of operational reliability when in use, since rescue operations must always be performed very rapidly. If, for example, a rescue appliance was exposed to adverse environmental influences (e.g. extreme heat) because of a prior deployment, this may have the result, for example, that seals in the region of the hydraulic lines have become damaged and, as a consequence, the operational fitness of the rescue appliance is no longer assured. When in use, this may have the result that the required performance of the appliance can no longer be achieved, e.g. owing to a resultant lack of tightness of seal, thereby impeding the rescue operation and consequently being to the detriment of the person to be rescued. Such appliances are thus used worldwide, and thus by a great variety of users.
Known from WO 2014/043190 A2 are a system and a method for identifying an electromechanical work appliance that can be carried and used autonomously by an operator, according to the preamble of claim 1. Each of the work appliances has an individual ID for identifying the individual work appliance. In this case, a backup unit is connected to the work appliance, and comprises a sensor, a storage device, a transmission means and a controller. During the operation of the appliance, the sensor senses occurring vibrations that necessarily occur during operation and directly indicate use, the vibrations being converted by the controller into frequency data and transmitted by wireless communication to a central analysis site. From this, the frequency of the previous use can be deduced. This known system allows only an approximate sensing of the use of the work appliance, by means of the vibrations produced during use. Moreover, this system requires not insignificant appliance-specific adaptations.
The object of the present invention consists in providing a method of the generic type that, on the one hand, renders possible a more accurate monitoring of the operation of a work or rescue appliance and that, on the other hand, can be realized with a manageable degree of complexity in respect of equipment.
The object is achieved, in the case of the method of the generic type, by the features of the characterizing portion of claim 1, and, in the case of the work appliance or rescue appliance of the generic type, by the features of the characterizing portion of claim 15.
Expedient developments of the present invention are claimed in the dependent claims.
The method according to the invention makes it possible to compile, from direct operating parameters P1-Pn and not only direct criteria, an exact actuation and/or load profile of the work appliance or rescue appliance over time, and to manage these data centrally for the purposes of analysis. It thereby becomes possible to compile an individual “usage history” for each individual appliance on the basis of exact operating parameters that enable the manufacturer to implement individual, problem-specific service measures. For example, the individual user can be informed that, as a result of a previous increased demand on the appliance, there is a need for exceptional servicing to be performed very soon. The electrical energy source of the work appliance serves in this case as a “transmitter” of the collected operating data. Since the electrical energy source of the respective work appliance must be charged from time to time in any case, it is ensured, as it were, “automatically” that the data transmitted from the work appliance to the electrical energy source are reliably called up from the charging device and fed into the network. The call-up and transmission are effected automatically. Moreover, in comparison with known solutions, the complexity in respect of equipment for this can be simplified considerably to the selection of suitable storage means and data interfaces for transmission of the data via the electrical energy source. The operating data of a multiplicity of work appliances or rescue appliances can be collected and subjected to data analysis in the network, or in a central data collection site located therein. In this way, from a multiplicity of individual appliances, a history can be compiled in the data collection site in respect of the respective work appliance or rescue appliance. This history can be used to identify at any time whether servicing measures are to be performed sooner than is usual, for instance because of prolonged use in adverse operating conditions, or whether, for example, certain parts must be replaced. This history is also particularly important in respect of the assessment of cases of damage and claims, if it is necessary to provide proof of whether the work appliance or rescue appliance has been operated in a proper manner.
According to an expedient development of the present invention, the electrical energy source may also serve as a “courier” for transmitting data/programs from the network back to the individual work appliance or rescue appliance. The data and/or programs (e.g. a firmware update) for operating the work appliance or rescue appliance can thus easily be transmitted to the appliance via the electrical energy source, without the need for intervention by the user.
Expediently, each work appliance or rescue appliance comprises an appliance-specific ID that is a constituent part of the operating data. As a result, each individual appliance is given its own electronic identity, such that the operating data in the appliance can be assigned exactly during the analysis of the latter. Each appliance can thus be scanned and centrally analyzed.
Expediently, the operating data are, preferably direct, operating parameters. Preferably, the latter may be acquired in the form of physical measurement data (e.g. the current instantaneously drawn by the electric motor) and stored in an appropriate data format on a timeline, via an appropriate interface, in the electrical energy source.
According to an expedient development, the operating parameters are at least one operating parameter, or any combination of a plurality of operating parameters from the following group:
Consequently, the invention makes it possible to construct an operating history, with a very great variety of data in each case, depending on the requirement, which enable a very precise assessment of the state and/or operating history of the individual appliance.
Expediently, the operating parameters are acquired on a timeline. The operating parameters, placed in a time relation or provided with a time stamp, can thus be subjected to an analysis. This makes it possible to assign operating parameters to a particular point in time or to a particular time period, and this, in turn, enables the operating history to be defined in an exact manner. The latter, in turn, allows exact determination of incorrect behavior during use, lateness in the performance of repair and servicing work, improper handling, and the like.
Preferably, the individual data arriving from the appliances are processed in the central data collection site, and a great variety of data records are created therefrom. Advantageously, the operating data are routed, as digitized, physical measurement data, or operating parameters, via the electrical energy source and the charging device, to the network, into the central data collection site. It is only there that the operating data undergo computational analysis and further processing. There is thus no need for any elaborate DP (data processing means) to be provided in the work appliance or rescue appliance itself for the purpose of further processing of the data. This can be performed, expediently, in the central data collection site.
Expediently, new data records can be generated in the central data collection site on the basis of the operating parameters. These records are, for example, the calculation of an individual service time point, a reminder message, a warning message concerning a detected or imminent malfunction, an error message, etc.
Expediently, the items of information, or data records, generated by the central data collection site are transmitted back to the individual work appliance or rescue appliance.
Expediently, this, in turn, may be effected via the charging device, or the electrical energy source, in the manner already described.
As an alternative or in addition to this, the information may also be transmitted to a DP device that is assigned to the individual work appliance or rescue appliance. For example, this may be a user's smartphone that is assigned to the user of the work appliance or rescue appliance, via an appropriate app. Consequently, information may be transmitted to the user's smartphone from the central data collection site, for example by short-range wireless communication (WLAN, WiFi, Bluetooth, etc.) and/or by mobile telephony connection. Alternatively or additionally, there may also be a corresponding display means on another user application, for example a headup display in the helmet.
Expediently, the exchange of data between the charging device and the network is effected by wireless communication, preferably by short-range wireless communication (such as, for example, WLAN, Bluetooth, WiFi, etc.).
According to a further expedient development of the method according to the invention, to enable meaningful information to be generated on the basis of the transmitted operating data, a computational analysis of the operating parameters is effected in the central data collection site, by comparison of the received operating parameters, or operating data, with the data of an empirical operating-parameter database.
Moreover, expediently, an appliance-specific operating history of the respective work appliance or rescue appliance, having the respective individual identity, can be generated in the data collection site on the basis of the operating parameters, and made available to the user.
The central data collection site additionally makes it possible to compile an experience database, in which information that is specific to the work appliance or rescue appliance can be input and/or called up by the user, wherein the experience database is generated in that users of the work appliance or rescue appliance input information data into the experience database, and the experience database can also be called up by users. This creates a further data information source, or the possibility of a comprehensive exchange of information that, on the one hand, can be used to assess the operating history of the appliances and, on the other hand, at the same time provides an additional benefit for the respective user.
Expediently, the central data collection site is a so-called computer cloud, which can be accessed via a network, preferably via the Internet. The computer cloud has the advantage that all computing tasks in respect of the further processing of the data relating to the operating parameters can be processed in the computer cloud.
The present invention additionally relates to an electromechanical or electrohydraulic work appliance or rescue appliance that can be carried and used autonomously by an operator, according to the preamble of claim 15. To achieve the object stated at the outset, the energy source has a data carrier or data storage device, in which the usage data of the sensor means can be stored.
Expediently, a data interface, preferably bidirectional, is provided between the work appliance or rescue appliance and the energy source. This may be a hardware interface such as, for example, a PCI bus, AGP, SCSI, USB or other firewall solution. Preferably, the processor of the work appliance, or rescue appliance, insofar as the processor is located in the latter, writes the data instantly to the data storage device of the electrical energy source via the interface. Alternatively, the processor could also be located in the electrical energy source.
Preferably, the interface is designed in such a manner that, during the insertion of the electrical energy source in the recess provided for this purpose on the work appliance and/or on the charging device, the data interface also simultaneously becomes active. Consequently, the data interface may be located in the region of the electrical contacting between the work appliance, or charging device, and the electrical energy source.
Expediently, a current sensor, a voltage sensor, a tilt sensor, a temperature sensor, a battery charge-state sensor, a battery charge-cycle counter, a GPS module and/or a humidity sensor is provided as sensor means. Expediently, a time recording means is provided. The GPS module has the advantage that, in addition to the location coordinates, it already includes a time recording means.
Expediently, the respective appliance comprises an analog/digital converter for the measurement signals corresponding to the operating parameters.
According to a further expedient development of the invention, the operating data and/or operating parameters and/or data records derived therefrom, thus, for example, the charge state of the energy source, etc., can be displayed directly, i.e. without being routed via the network, on a display assigned to the work appliance or rescue appliance, e.g. a headup display and/or a display disposed directly on the appliance and/or a display taken along by the user. The data in this case can preferably be transmitted directly to the display by a short-range wireless communication means of the work appliance or rescue appliance.
The present invention additionally comprises a chargeable electrical energy source for a work appliance or rescue appliance, according to at least one of claims 15 to 18, the energy source having a housing, at least one charge cell, preferably a plurality of charge cells, and an electrical contact region for electrical connection to the work appliance or rescue appliance or to the charging device. Additionally provided on the energy source are a data interface, preferably bidirectional, and a data carrier or data storage device, in which operating data of the work appliance or rescue appliance can be stored. These are data that, by means of sensors on the work appliance, pick up the operating data, or operating parameters, on the latter and store them in the data carrier, or data storage device, of the electrical energy source.
Expediently, a corresponding sensor may also be provided in the region of the battery itself, such as, for example, a battery charge-state sensor and/or a battery charge-cycle counter. The measurement values of the corresponding sensors are likewise read out via the data logger and transmitted to the data carrier, or data storage device, of the electrical energy source.
According to an expedient development of the present invention, in dependence on the respective data record, information corresponding to or generated concerning the latter is transmitted back to the individual work appliance or rescue appliance, from the central data collection site to the individual work appliance or rescue appliance. For example, if it is ascertained in the central data collection site that the individual appliance urgently requires replacement of seals because of exceptionally high loading in high ambient temperatures, this is transmitted back to the individual work appliance or rescue appliance and relayed, for example, to a display on the appliance. Alternatively, this may also be effected via an app, which displays the information, for example, on a portable computer, PC, smartphone or the like of the user.
An expedient development of the present invention is explained in greater detail in the following. There are shown in:

The communication protocol is preferably a short-range wireless communication protocol (e.g. Bluetooth, WLAN, WiFi, etc.). Equally, an individualized wireless communication protocol or network of a non-standardized frequency band may also be used. As can be seen from

S1-Sn denotes at least one sensor means, preferably a plurality of sensor means, by which at least one operating parameter P1-Pn of the appliance is acquired. These operating parameters P1-Pn, acquired by the respective sensor means S1-Sn, are read out by a data logger 16A. In this case, preferably physical measurement values of the respective sensor means S1-Sn are converted into an appropriate data format, and written by the processor 16, via the data interface 10, into the data carrier, or data storage device, 6d of the energy source 6.
Expediently, the sensor means are a means for measuring the current and/or the voltage drawn by the electric motor 4, and/or the charge state of the energy source 6, and/or the charge cycles of the energy source 6, and/or the ambient temperature, and/or the ambient humidity.
In

The operating parameters are at least one operating parameter or a combination of operating parameters from the following group:
Furthermore, each appliance has an appliance-specific, individual identity ID1-IDn. This individual identity ID may be defined, for example, by a consecutive binary number.
It is pointed out that the representation of the individual functional elements in

In this way, all operating parameters P1-Pn of all individual appliances ID1-IDn world-wide can be stored in the central data collection site 20 and held ready for analyses. A usage history for each individual appliance can thus be stored in the central data collection site 20.
As shown by
This makes it possible, for example as represented in
Alternatively, the information may also be transmitted from the user's data processing device 15 to the display means, i.e. to the headup display 23.
The functional block Network 20F relates to the handling of network matters. The functional block User Info Management 20L relates to the compiling of information transmitted back from the central data collection site 20 to the individual users. The functional block Communication Management 20G relates to the handling of communication measures, such as selection of the transmission protocols, etc. The functional block Experience Database 20M relates to the receiving and maintenance of user-specific information, which, in turn, can be retrieved by other users.
According to a further expedient development of the invention, shown in
The present invention enables individual appliances, used in a great variety of deployment locations, to be monitored with precision in respect of their use and analyzed fully, in a very simple manner. This, in turn, enables unforeseen delays in the deployment of rescue appliances to be precluded in a reliable manner. The invention therefore contributes very significantly to improvement of the deployment conditions of rescue appliances.
