CS256108B1 - An automated unit for inspecting entrances to objects - Google Patents

Abstract

The automated unit for controlling persons entering buildings consists of side panels, one of which houses a microcomputer, to which are connected an identification card reader, a decimal keyboard, optical barriers, a closing mechanism and an electronic platform scale and a platform switch, which form a divided floor between the side panels. The electronic platform scale, the platform with a platform switch and the optical barriers enable the evaluation of the movement of a person in the unit, the determination of their weight and the determination of the attempt of several persons to pass simultaneously.

Description

BACKGROUND OF THE INVENTION The present invention relates to an automated object entry control unit comprising a microcomputer, an identity card reader, a decadic keypad, an electronic platform scale, a platform with a switch, an optical barrier system and a locking mechanism.

Previously known entrance control units use either a cab structure, which has the disadvantage of · low throughput of persons at the checkpoint, or in other construction they do not allow control of the person's weight, evaluation of its movement in the unit with other devices.

and

These drawbacks are eliminated by the device according to the invention, characterized in that an electronic platform scale and a platform switch, which form part of the divided floor between the sidewalls, an optical barrier system, an ID card reader, a decimal keyboard and a closing mechanism are connected to the microcomputer. The microcomputer is located in one of the side panels on which the ID card reader, the decimal keyboard, the system of optical barriers and the closing mechanism are located. The microcomputer is connected via a connection to other devices.

The advantage of the device is that the system of optical barriers together with an electronic platform scale and a platform with a switch enabling evaluation of the movement of a person in the unit, determination of his / her weight and ensuring the effort of simultaneous passage of more than one person. This significantly reduces the possibility of an unauthorized person entering the protected area.

Figure 1 shows a group diagram of an automated unit for controlling the entry of persons into an object. The ID card reader 3, the decadic keypad 4, the electronic platform scale 2, the platform switch 9, the light barrier assembly 5 and the closing mechanism 11 are connected to the microcomputer 10 with connection.

Figures 2 and 3 are a front view and a plan view of a possible embodiment of an automated unit for controlling persons entering objects. Between the side panels 12 there is a partitioned floor formed by a platform electronic scale 2 by the switch 9 of the platform 9. In the side panel 12 there is a microcomputer 10, optical barriers 1 and its closing mechanism 11 and auxiliary indicators 13 and 14. and decimal keyboard 4.

The function of the device is as follows: Auxiliary first indicator light 13 indicates the readiness of the unit for inspection. The person entering in the permitted direction is indicated by an optical barrier 2 * ID card reader J3 is after entering the person's ID card content, at the same time the weight of the person standing on the electronic weighing platform 2 is detected. identification cards 3, decadic keypad 4 and electronic scales 2 evaluated by microcomputer 10.

After evaluation, the microcomputer 10 either lights up the second indicator light 14 to indicate a possible passage or closes the shut-off mechanism 11 which prevents passage between the sidewalls 12. In the case of a possible passage indication, the light beam interruption 6 is allowed. Where indicated the possible passage and when an interruption of the beam optical gates 6 or entry to the platform with the switch platform 2, ³ and the closing mechanism 11 is also closed.

Leaving the unit by a person is indicated by the optical barrier 8 and the release of the platform with the platform switch j). By evaluating the time sequence of intersection of the beams of the optical barriers i * of the presence of a person on the electronic weighing platform 2 or the platform is

Allowed evaluation of a person's movement in the unit. In the event of an interruption of the beam of the photocell or the entrance to the platform with the switch 9 in the unauthorized direction, the shut-off mechanism 11 is actuated. The sidewall 12 is designed to contain all the necessary devices checkpoints with greater throughput. When the connection to other cooperating devices is interrupted, the unit is put in an autonomous mode of operation, whereby the connection-dependent control functions are degraded, but the passage through the unit is not prevented.

The unit for control of persons entering the buildings can be used in automated systems of security of buildings and in systems of registration and space-time control of persons. If the security requirements of the protected objects are reduced or the throughput of the unit is increased, the decimal keyboard 4 can be omitted.
