Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a five-portable transmitter that transmits information using a modulated optical signal having a registered code number given to each individual in advance.

2. Description of the Related Art Magnetic cards and punch cards are conventionally known as portable storage media having individually assigned registration numbers. As a service for bank counter operations that utilizes such storage media, depositors are issued with a special cash card W, which is used in combination with a code number to confirm whether the depositor is the person in question, so that cash can be withdrawn even on holidays. The company operates an automatic payment service that pays cash. In addition, in buildings or rooms that require certain types of confidentiality, special cars are handed out only to those who have been given permission in advance, and are used for automatic crowd control to verify the identity of people when they leave. There is.

However, checking the registration number of magnetic cars Y, punch cars R, etc. requires operating the machine to read the car R with a dedicated reading device. For example, when used for automatic crowd management, both hands are required I felt inconvenienced when it was blocked.

Furthermore, since it has a mechanical coupling means, there are problems with life span and reliability, and the environment in which it can be used is also limited.

The present invention overcomes the various drawbacks mentioned above.

The present invention makes the transmitter that outputs optical signals smaller and lighter by using solar cells for its power supply.

By making it into a portable shape such as a rose ψ, it can be easily attached to the chest of clothes, a hat, etc., and by simply pointing one light emitting part toward the light receiving part, the registration number Knee-ν'*g can be obtained without the need for troublesome mechanical operations. The purpose is to

The portable transmitter according to the present invention will be described in detail below according to embodiments.

Since this example requires some kind of confidentiality,
This is a portable transmitter device attached to the automatic door of a room that only authorized persons can enter.

FIG. 1 shows a circuit diagram of a portable transmitter 1 according to the invention. The registration number given to the person who is permitted to enter the room can be set in the registration number need setting section 11, and 256C
8) It is possible to set the classification. The control unit 12 is composed of a one-chip CMOB/microconverter, and in addition to the individual registration numbers knee r, a start code is added to the beginning, a stop knee r and a parity code are added to the end, and further original modulation is performed. The light emitting unit 13 outputs the original modulated electrical signal to the outside as an infrared light signal.

The power supply section 14 uses a solar cell to supply power to each section.

FIG. 2 shows a circuit block diagram of a receiver 2 for receiving optical signals from a portable transmitter according to the invention shown in FIG.

The infrared light signal output from the transmitter 1 is received by the first light receiving section 21 when one person is in the room, and is received by the second light receiving section 22 when the writer is outside the room, and is converted into an electrical signal. . Since the converted electrical signal has been subjected to original modulation, it is demodulated into a logic level signal by the first filter 23 and the second filter 24 and input to the controller 25. The controller 25 judges the acceptability of the input logic level signals such as start code r1 start code r1 validation code Y, etc., and verifies whether the person is an authorized person who has made the settings in the permission number need setting section 26. Then, a signal for opening/closing an automatic door (not shown) is output to the outside. On the monitor part 27, various data such as entry/exit room classification, time, registration number need, etc. are printed on a specific paper at the same time as the automatic gate is opened/closed.

The figure is a plan view showing the configuration of the transmitter shown in FIG. 1, and FIG. 4 is a side view of FIG. 3.

In FIGS. 3 and 4, 31 is an infrared light emitting diode, and 32 is a power source, which uses a solar cell. Reference numeral 33 denotes a control section, which is composed of an LSI chip of a microcomputer having various functions. 34 is a basic case. FIG. 5 is a diagram showing an example of use of the portable transmitter according to the present invention. In FIG. 5, a transmitter 1 carried by a person 43 is illuminated from an auxiliary land 42 installed on a wall 41 as a source of light energy for the solar cell, and the light energy causes the transmitter 1 to continuously output optical signals. Ru. On the other hand, the receiver 2 similarly installed on the wall 41 detects this optical signal and the controller 25
After demodulation, knee P verification, etc., a door (not shown) is controlled. Further, normally, the auxiliary lamp 42 is off, and the auxiliary lamp 420 is turned on and off only when the detector 44 detects a person 43. In the above-described embodiment, light was used as a propagation means for the need signal, but it is obvious that the present invention can also be easily carried out using weak radio waves or sound waves.

As described above, the present invention eliminates the need for troublesome mechanical operations (in addition to being able to confirm the registration number).

By using communication methods such as optical signals and modulation, there is no mechanical wear during reading, increasing reliability and longevity. Furthermore, since a solar battery is used as the power source for the transmitter, it has the excellent effect of being able to be used continuously semi-permanently without the need for charging or replacing batteries, even though it is portable. The present invention not only controls the opening/closing of the automatic rare according to the embodiment, but also fully fulfills the role of a general locking key.
