Checking system and method for verifying checking stations in a monitoring system
First Claim
1. A control system having at least one stationary control point, each control point having a contactlessly queried data carrier containing an identification, a data collector associated with the control points for verifying the individual control points, the data collector having a data reading head for serially reading the identification as the data collector moves across the data carrier, an electronic memory connected to the data reading head for receiving the data conforming to the identification, a transmitter for transmitting to a central unit the data corresponding to the identification, and an emergency call key for switching on the transmitter, wherein:
- said data collector further including a microprocessor for controlling said memory and said transmitter, a clock chip whose time data together with the identification data is transmitted and stored in said central unit, a random generator and an optical display whereby random sequences of control points may be input and the corresponding data carriers sequentially identified on the display as determined by the random generator;
said transmitter further including a receiving unit, the transmitted data and a verification entry received by the receiving unit from said central unit are transferred to said memory, and means causing said transmitter to repeatedly transmit the identification data and time data at time intervals until a verification entry is received by the receiving unit from the central unit;
said memory being adapted to store all data of a route which encompasses several control points;
said central unit comprising a computer which interprets the routes and is connected to a central printer; and
means for automatically transmitting an emergency call to said central unit when a time range associated with each control point within which a respective control point must be verified is exceeded, said emergency call identifying the non-verified control point.

Abstract
A control system is provided having stationary check points which are contactlessly read by a data collector and verified. The data so read can be stored and transmitted by a transmitter to a central unit, where the data so received are centrally evaluated. Together with the data of the check point being read, the time at which the respective check point is read is transmitted to the central unit as well. If all data are received by the central unit, it transmits back a verification entry, and the data are subsequently stored in a memory together with such verification entry. If no verification entry is received, the data are automatically and continually retransmitted to the central unit until the verification entry is received by the receiver in the data collector. In addition, the data collector has a random generator capable of establishing which individual check points are to be successively called on by the security guard. Each check point is to be called on within a time range and, if such time limit is exceeded, an emergency call is automatically transmitted to the central unit.

11. Method for verifying check points in a monitoring system, the verification comprising an item of time information and an identification associated with the respective check point, wherein the identification data are serially sampled by means of a data collector 10 and are stored, ready for being called up, in a memory 54, 56, and the identification data and the items of time information of the verification are transmitted at repeated intervals, until a confirmation relating to the reception of the transmission is received in a data-collector receiver 71 from a receiving central station 74.

13. Method for verifying check points in a monitoring system, the verification comprising an item of time information and an identification associated with the respective check point, wherein the identification data are serially sampled by means of a data collector 10 and are stored, ready for being called up, in a memory 54, 56, and each check point is associated with a "time window" within the range of time of which the respective check point must be verified and that, when a time window is exceeded, an emergency call, specifying the non-verified check point, is automatically transmitted to the receiving central station 74.
