Definitions

• the invention is based on a radio network according to the preamble of the main claim.
• time clocks So-called time clocks are known, with which security personnel are equipped for object protection.
• the security guard must "stab" with a code key on an object to be monitored at predetermined locations that are equipped with a code key.
• the code key is inserted into the time clock, the predetermined location is registered on the watchman's time clock and printed out on a paper strip together with the time running in the time clock. With the help of the time clock, it is possible to check whether the security guard has passed his security round in accordance with the regulations.
• this method has the disadvantage that a check can only be carried out after the guard round, so that there is a certain degree of uncertainty during the guard round, since it cannot be determined where a security guard is at the time in question, unless the security guard can be reached and queried by radio.
• the radio network according to the invention with the characterizing features of the main claim has the advantage that the watch of a security guard can be tracked and checked at any time in order to determine whether the security guard on his round of security corresponds to that passes the checkpoints or whether the security guard may not start a checkpoint.
• Another advantage is that the identifier that can be entered via a coding device is designed in such a way that the identifier cannot be manipulated improperly.
• the measures listed in the subclaims achieve advantageous configurations of the radio network specified in the main claim. It is particularly advantageous that the identifier in the first part of the information content is designed as an identification code for the security guard in question.
• each security guard is equipped with a handheld radio that contains a device for transmitting an identifier, for example an encodable identifier.
• the identifier in the identifier is encoded in a first part of its information content on the security guard in question and contains a specific code in a second part of its information content.
• the specific code can be coded by external measures on the control point that the security guard calls during his watch. Preferably one takes place such coding via a suitable type of coding plug to be inserted or inserted into the device from the outside.
• the coding can be done by mechanical contacts, by electron-optical scanning, by magnetic scanning or the like.
• the coding plug is therefore inserted into the identifier or placed on the identifier.
• a "contact" is actuated, for example, which can be designed both mechanically and electronically, so that the identification is emitted in this way.
• the identifier is recorded in the control center of the radio network or in the radio control center and decoded in a corresponding device, for example in an identifier evaluator. Due to this process, the current location at which the security guard is currently located is known.
• the incoming information can be registered together with the time taken from a time source, for example on a printer. In this way, the guard round can be checked immediately, so that any irregularities that occur are immediately recognizable.
• the information about the individual security rounds of each security guard can also be stored in a data processor, so that the time and the control point of the security round are recorded.
• a data processor so that the time and the control point of the security round are recorded.
• the incoming information is tracked and evaluated in the data processor. The evaluation can take place either on a printer and / or in a suitable manner on a screen, for example in a graphic representation.
• the acknowledgment can consist only of a "beep" which is emitted by the radio center.
• the acknowledgment tone in the security guards' portable handheld radios is generated by selective call evaluation itself.
• the identifier can be arranged both in the radio and in a small hand part, which is connected to the radio by cable.
• the hand part can contain the necessary devices for carrying out normal radio communication, for example a microphone, loudspeaker, transmit button and the like.
