Description

An infrared alarm device for non-operation area of portable substation

technical field

The invention proposes a safety device in the field of electric power, in particular an infrared alarm for non-operation areas of portable substations.

Background technique

Nowadays, my country's industry is becoming more and more developed, the demand for electricity is increasing, and the maintenance of the power system by power companies is becoming more and more frequent. When the staff perform maintenance on the power system, the non-working area is very dangerous for them. At present, there are several incidents of electric shock casualties caused by staff straying into the non-working area every year, which have caused great harm to the country, enterprises and individuals. huge loss. Therefore, it is necessary to carry out warnings and safety reminders for these non-working areas. The traditional method is to use the rope-enclosing method, which is to use a warning rope to surround the non-working area. This method has many shortcomings, such as large material consumption, inconvenient carrying, and no auditory warning. As a new type of alarm system, the sound and light alarm system has many advantages such as small size and easy maintenance. However, most of the acousto-optic alarm systems currently on the market are used for anti-theft alarm systems, which do not involve safety warnings for non-working areas of substations. They are all fixed and inconvenient to carry. Once installed, the warning range cannot be adjusted. , the power supply methods they adopt are all direct charging power supply, so the scope of use is limited.

Contents of the invention

In order to overcome the shortcomings of the existing technology, the invention proposes an infrared alarm for non-operational areas of portable substations. The alarm is composed of an infrared transmitter and an infrared receiver, and an infrared alarm is installed on the infrared receiver. Solve the technical problem of approaching the alarm in the non-operating area of the substation.

The scheme that the present invention solves technical problem adopts is:

The infrared alarm consists of an infrared transmitter and an infrared receiver.

Infrared emitter: An infrared emitting tube is installed on the base of the infrared emitter through a rotary joint and a column, an infrared generator is installed in the infrared emitting tube, and an infrared transceiver control board is installed, and a transmitting end is installed between the column and the base control box;

Infrared receiver: An infrared receiving tube is installed on the base of the infrared receiver through a rotary joint and a column, an infrared receiver is installed in the infrared receiving tube, an infrared transceiver control board is installed, and a receiving end is installed between the column and the base The control box is equipped with an alarm on the rotary joint or the control box at the receiving end.

A relay is arranged in the infrared receiver, and the relay is connected with the alarm driving circuit.

A lithium battery is housed in the base.

The receiving end control box and the transmitting end control box are equipped with a wireless transceiver module, and the power supply is connected with the alarm driving circuit through a single chip microcomputer.

Positive effects, the invention is composed of an infrared transmitter, an infrared receiver and an alarm, which can realize the approach alarm of the non-operation area of the substation and prevent the occurrence of electric shock accidents. It has the advantages of beautiful appearance, small size, easy to carry, convenient to use, safe and reliable. It is suitable for application as a safety alarm device in non-working areas of substations.

Detailed ways

As shown in the figure, the infrared alarm consists of an infrared emitter 0 and an infrared receiver 00.

Infrared emitter: on the base 6 of the infrared emitter, an infrared emission tube 1 is installed through a rotary joint 3 and a column, an infrared generator 8 is housed in the infrared emission tube, and an infrared transceiver control board 10 is housed, between the column and the base A transmitter control box 4 is installed between them;

Infrared receiver: An infrared receiving tube 2 is installed on the base of the infrared receiver through a rotary joint and a column, an infrared receiver 9 is installed in the infrared receiving tube, and an infrared transceiver control board is installed. The receiving end control box 5 is equipped with an alarm 7 on the rotary joint or the receiving end control box.

A relay 11 is housed in the infrared receiver, and the relay is connected with the alarm drive circuit.

Lithium battery 12 is housed in the base.

A wireless transceiver module 13 is housed in the receiving end control box and the transmitting end control box, and the power supply is connected with the alarm driving circuit 15 through a single-chip microcomputer 14 .

Working process of the present invention:

The use of the present invention is realized by taking the "pair" of infrared emission and infrared reception as a unit, and multiple pairs can be used simultaneously or individually, a pair and a transmitting end and a receiving end. The function realized by one pair is to give a safety warning to a single side, and multiple pairs of alarms are required for multi-sided safety warnings, and the staff can choose the number of pairs of alarms according to the needs of the site.

Take a pair as an example:

The invention adopts the principles of six beams of infrared beams and double beams of identification, only when two adjacent beams or more than two beams of infrared rays are blocked at the same time, a signal is sent out, which avoids misoperation. Infrared rays form a "wall" between the infrared transceiver tubes, and an interrupt signal is generated when someone enters by mistake; the control device of the present invention uses an Atmega16 single-chip microcomputer, and the single-chip microcomputer detects this signal end in real time. Signal, the controlled sound and light alarm will give sound and light alarm to prevent people from entering by mistake. At the same time, the wireless communication module controlled by the single-chip microcomputer sends a signal to the host to inform that someone has entered by mistake; the host can obtain the specific side by which someone has entered by mistake through the translation of the signal, and at the same time send information to the upper computer through the GPRS module, and display the detailed situation of the scene through the upper computer. In this way, the staff or security personnel can accurately receive the alarm information, and the people who stray into the dangerous area can find the danger in time to ensure their own safety.

The present invention has the following advantages:

1. Intelligent Judgment: Adopting the principle of multi-beam infrared radiation and double-beam recognition, it will send out a signal when two adjacent or more than two infrared beams are blocked, effectively avoiding misoperation.

2. Adopt wireless communication technology: it can make the staff understand the situation of the alarm scene in time.

3. The present invention uses infrared rays instead of the traditional rope-enclosing type, which is convenient and reliable.

4. The invention adopts lithium battery for power supply, avoiding the limitation of direct charge type.

5. The alarm logarithm can be selected according to the actual situation, and its protection range can be adjusted within a certain range. the
