- JRU juridical recording unit
- the invention relates to a protected storage unit with a trip registration data storage module for electronic trip registration of ground-based vehicles and with a heat protection device for the trip registration data storage module, in which the heat protection device has a protective housing, in the interior of which the trip registration data storage module is arranged, wherein the protective housing is provided with a heat-absorbing material and covered with a heat-insulating material.
- the invention also relates to a method for producing a protected storage unit which is provided with a trip registration data storage module for electronic trip registration of ground-based vehicles and with a heat protection device for the trip registration data storage module and in which the heat protection device has a protective housing in the interior of which the trip registration data storage module is arranged, in which the protective housing is covered with a heat-absorbing material enveloping the trip registration data storage module and is covered with a heat-insulating material.
- the invention relates to a ground-based vehicle, in particular a rail vehicle, with a data processing system which is set up to provide, at an interface, state parameter data of the ground-based vehicle which are selected for electronic trip registration of the ground-based vehicle, and with a protected storage unit which can be connected to the data processing system, wherein the protected storage unit is set up to receive and store the state parameter data when connected to the data processing system, and wherein the protected storage unit is set up to output the stored state parameter data to the data processing system or another data processing system if necessary.
- earthbound vehicles are understood to mean rail vehicles and motor vehicles.
- a generic protected storage unit, a generic method for producing a protected storage unit and a generic ground-based vehicle with a protected storage unit are known from the publication CN 206964921 U. Proceeding from this, the invention is based on the object of providing a generic protected storage unit, a generic method for producing a protected storage unit and a generic ground-based vehicle with a protected storage unit in such a way that the protected storage unit is characterized by a particularly reliable protective function.
- the heat-absorbing material comprises at least one sugar alcohol which has a melting temperature between 90 ° C and 130 ° C, in particular between 115 ° C and 125 ° C.
- a significant advantage of the protected storage unit according to the invention is that in the event of a fire - during a possible accident - the trip registration data storage module retains its functionality as a storage medium until the protected storage unit can be recovered by appropriate emergency services, for example firefighters. In the event of a fire, it can thus be ensured that if the protected storage unit is exposed to temperatures of up to 700 °C or even up to 750 °C over a long period of time, the trip registration data storage module inside is not exposed to a temperature above 130 °C and thus, for example, plastic components of the trip registration data storage module cannot melt.
- meso-erythritol (CAS No. 149-32-6) and/or xylitol (CAS No. 87-99-0) is used as heat-absorbing material.

- the protective housing 41 is made of metal, in particular of steel. It has a pot-shaped section 41a and a lid-shaped section 41b placed on its open front side, in particular screwed on.
- Meso-erythritol has a melting temperature (melting point) of approximately 120°C, a boiling temperature (boiling point) of approximately 330°C and an enthalpy of fusion of approximately 337 J/g.
- Xylitol has a melting temperature (melting point) of approximately 100°C, a boiling temperature (boiling point) of approximately 215°C and an enthalpy of fusion of approximately 269 J/g.
- the heat-insulating material 43 is microporous, in particular made of inorganic silicates and/or silicon carbide. It has a thermal conductivity between 0.02 W/mK and 0.07 W/mK.
- the trip registration data storage module 30 has a module housing 31 and a data storage module 32, wherein the data storage module 32, which is designed here by way of example in the form of a data storage card, is arranged in the module housing 31.
- the module housing 31 is made of metal, in particular steel. It has a tubular section 31a and two cover-shaped sections 31b inserted, in particular screwed, into its open end faces.
- the two separate cover-shaped sections 31b each have a screw slot 31c.
- the cover-shaped sections 31b can be screwed into the tubular section 31a - for example, under This can be done easily using a screwdriver that fits into the screw slots 31c.
- One of the two screw slots 31c also serves as a hole for the connecting cable harness 22.
