ES2270668A1 - Electronic detector for individual protection equipments in delimited zones, has receiving circuit that for receiving and decoding signal sent from equipment, and logic circuit for determining presence of equipment based on decoded signal - Google Patents

Abstract

The detector has sensors placed in individual protection equipment in predetermined positions, and connected to a signal generating circuit. The signal generating circuit produces and transmits a signal or code with power to a wireless transmitter. A receiver circuit has one or several sensors to detect the signal transmitted from the individual protection equipment which is arranged in a work zone. The receiving circuit decodes the received signal or code, and sends the decoded signal to a logic circuit which determines the presence or absence of the individual protection equipment.

Description

Electronic detector of protective equipment individual in delimited areas.

The present invention relates to the detection of Personal Protective Equipment (E.P.I.) in places delimited They are understood as personal protective equipment all  device that serves to protect the individual, whether they are helmets in delimited areas, goggles for use with a tool, protective vests in enclosures, gloves, etc ..., thanks to which you can notify or block the device  work if the E.P.I. correspondent.

Background of the invention

As is known, the use of equipment Individual protection prevent large number of accidents, even now there is no known circuit capable of detecting that a individual is wearing the necessary protective equipment to use a machine or enter an enclosure and therefore there is no no circuit that acts when the Equipment is not in place Adequate Individual Protection

With the present invention it can be detected if the individual is wearing the E.P.I. within an area and act in consequence.

Description of the invention

The E.P.I. will be formed by two devices, one connected to the E.P.I. what we will call Device E.P.I. and another in the place where you want to detect the use of E.P.I.  what we will call E.P.I.

The E.P.I. It will be formed by:

-

Sensors connected to the E.P.I. that detect that the E.P.I. is placed.

-

A generator of a signal or code.

-

A Signal emitter.

The operation of these elements will be the next: The generator will deliver a signal or code to the issuer of signal when the E.P.I. are activated, with a power and direction such that the receiving device of E.P.I. can receive said signal from the delimited area.

The receiving device E.P.I., will be formed by:

-

A receiver capable of reading the signal or code emitted by the device E.P.I.

-

A detector circuit that detects or decodes the signal or code issued by the E.P.I.

-

A logic circuit that controls the actuators at convenience.

-

Actuators

The operation of these elements will be the next: The receiver will pick up the signal emitted by the device E.P.I., this signal will be decoded by the detector circuit and if the signal is correct will send a signal to the logic circuit, indicating that the E.P.I. It is placed at that time. He logical device will act on the actuators in the way that Consider convenient.

Brief description of the drawings

For the best understanding of how much is left described herein, are accompanied by drawings that They will help to understand the present invention.

Figure 1 shows a diagram of blocks of the E.P.I. in which they are indicated:

one-

Detector sensors These sensors or detectors will be the circuits that detect that the E.P.I. is placed correctly.

2-

Signal generator This block will be the circuit that will generate the signal or code to be emitted and will be activated when the detector sensors (1) are activated correctly.

3-

Issuer will be the device that issues the signal or code generated by the signal generator (2).

Figure 2 shows the receiver circuit from E.P.I. formed by:

4-

Receiver will be the receiving device of the signal emitted by the E.P.I. of the figure one.

5-

Signal detector circuit This device will be the one that detects or decodes the signal received by the receiver (4) generating a signal at the exit when it receives the code issued by the E.P.I.

6-

Logic circuit This device receive the signal from the signal detector circuit (5) and activate the signaling devices or actuators (7) as deemed appropriate.

7-

Signals / actuators. These devices will be those that act warning that it is not put on the E.P.I. or blocking the use of machines, doors etc.

Description of a preferred embodiment

The following describes the detection of a motorcycle helmet, which conforms to the specifications of the present invention, ie an E.P.I. what is the helmet of Motorcycle and a delimited area, the motorcycle. The application of The invention in this case will have the E.P.I. in the helmet, and the E.P.I. on the motorcycle

The E.P.I. located in the hull will be formed by:

-

2 Sensors connected to the helmet as follows:

-

Sensor 1. Sensor placed inside the helmet that detects that the helmet is placed on the user's head.

-

Sensor 2. Sensor connected to the helmet's fastening strap and that it detects The belt has been closed.

-

Code Generator This circuit is will activate when Sensor 1 and Sensor 2 are activated simultaneously and will activate the code generator.

-

Transmitter signal This circuit will be a wireless transmitter that will transmit the code issued by the code generator at the address of the signal receiver located in the front area of the motorcycle and sufficient power to be received by the receiver from any correct hull position.

The operation will be as follows: When the sensor 1 and sensor 2 are activated will start the code generator that will transmit it through the signal emitter with a power and direction such that it can be received by the E.P.I. from all possible correct positions of the helmet.

The E.P.I. will be located in the motorcycle and will start when the contact is activated the motorcycle. This circuit will consist of:

-

A signal receiver This circuit will receive the signal emitted by the helmet from all possible correct positions of the helmet.

-

A detector circuit that reads the code issued by the device E.P.I. from the helmet and take a logical one at the exit every time Get the correct code.

-

A Logic circuit that works as follows: while not Receive a logic 1 from the detector circuit, activate an audible signal indicating that the helmet must be put on and also activate a boot lock signal, so that it cannot be put on Start the vehicle if the helmet is not on. Once received the code issued by the helmet deactivates the warning signal and will deactivate the lockout / stop, allowing the use of the vehicle. Yes after this the code is stopped receiving for a while, it the warning signal will be activated first, and if another time has elapsed, still not receiving the code will activate / stop the motorcycle, stopping the vehicle.

-

Actuators In this case the actuators It will be two that are:

-

A sound indicator that the helmet is not worn.

-

A blocking relay that interrupts the coil supply responsible for supplying spark plugs vehicle.
