And a wireless integrated radio transmitter for a fire alarm system that integrates its role as a local receiver and establishes a fire monitoring system.

The current fire alarm system transmits the fire alarm signal of the detector to the repeater terminal by wire, and the repeater and circuit line divide the signal and send it to the main receiver.

And R or P type transmitter has a built-in switch that can artificially alarm the fire. In case of fire, press this switch to send the fire signal directly to the receiver or to the repeater and the repeater sends this alarm signal to the main receiver. I can send it.

Conventional transmitters are provided with a jack for a telephone terminal separately, but a jack for audio is used instead of a general universal telephone terminal jack has a disadvantage that can not be used unless a special-purpose telephone.

On the other hand, in the current facility, the repeaters and transmitters are separated by their functions, so everything has to be installed regardless of the large, medium or small size of the facility. have.

In addition, from another point of view, when the expansion or use of the building is changed, there is a lot of inconvenience because it is not easy to install or repair the fire equipment.

In particular, high-rise buildings and basement floors are exposed to the danger of fire because they are not easy to maintain or repair wiring and circuits due to wired installation of repeaters, transmitters, or receivers.

The present invention has been made to solve the above problems, and can be used in combination with a wireless detector and a general wired detector, by integrating a repeater, a transmitter and a receiver to build a single fire monitoring system regardless of the specificity of the facility fire alarm Its purpose is to provide a quick and easy way to respond to a fire by simply and simply installing a wireless integrated radio transmitter.

The present invention provides a wireless alarm transmitter for fire alarm having a receiver and a repeater function to overcome the above problems.

The wireless alarm transmitter for fire alarm compensates for the shortcomings of the prior art so that the wireless detector and the wired detector can be used in parallel. The alarm signal of the wired and wireless signals is digitized to provide a local receiver including the functions of the transmitter and the repeater. Its role was to integrate and work.

In addition, a speaker and a microphone are built in the wireless integrated transmitter itself to enable two-way communication with the general disaster prevention room (or main receiving panel) with one call button in an emergency.

This makes it possible to construct a disaster prevention system suitable for the size and facilities of a building, and in reality, it is easy to match with the R-type receiver which is widely used, so that even if the existing building is expanded or changed in use, no other equipment or wiring is needed. It can operate the combined functions of the repeater and the transmitter wirelessly, and also plays the role of the receiver, so it can be integrated as a fire monitoring system.

In the present invention described above, the repeater, the transmitter, and the receiver are constructed as a single fire monitoring system, so that the installation of a fire alarm wireless integrated transmitter is easy, simple, and free, which can reduce costs, and the installation of wires is very difficult. Early detection of fires and early warning of fires in high buildings and other major facilities can minimize the damage caused by the initial response of the fire.

Hereinafter, the configuration of a wireless alarm transmitter for fire alarm having a receiver and a repeater function according to the present invention will be described in detail with reference to the accompanying drawings.

Wireless alarm transmitter for the fire alarm of the present invention,

A power supply unit 1; A circuit monitoring unit 2; A fire monitoring unit 3; A data transmission unit 4; A communication port 5; It consists of the Bluetooth module 6.

The power supply unit 1 may use a commercial power supply and a reserve power supply together, and the reserve power supply is used when there is no commercial power supply or when it is impossible to use due to a power failure.

The commercial power (AC 220V) input to the power supply is subdivided into ± 3V, ± 5V, ± 24V, and rectified and DC to remove AC ripple voltage.

Applying this voltage and current to the constant voltage regulator supplies the internal circuitry while maintaining a constant voltage.

In addition, a charging regulator with an overcharge protection circuit is used to charge a rechargeable lithium battery or lithium ion battery.

In order to monitor and indicate the abnormality of voltage, the voltage monitoring system is applied to display overvoltage, undervoltage and steady voltage using the color of LED. And the indicator of the transmitter was also displayed using the voltage here.

The circuit monitoring unit 2 operates the LED of the photocoupler PC-1 at all times by using a DC 24V voltage and a current through a terminal resistance (10ΚΩ) in the case of the conventional wired detector (7). Check the output of LOW or HIGH to check the circuit for disconnection.

That is, if the LED of PC-1 is turned on, the output is judged to be low and normal. If the circuit is disconnected, the LED of PC-1 is turned off and the output is HIGH, and if the output changes to HIGH, it is determined to be disconnected.

Therefore, PC-1's output change is displayed on the final LED Dispaly.

If the monitoring target is a wireless detector (8), the address number assigned to the wireless detector (8) itself is coded and repeatedly circulated for a predetermined amount of time to communicate with the receiver to read the abnormality and display the abnormality on the final LED display. do.

The fire monitoring unit 3 may be the same method as the circuit monitoring, but the singularity is as follows.

That is, when the wired and wireless detectors 7 and 8 operate and the contacts inside the wired and wireless detectors 7 and 8 are turned on, the voltage of DC 24V is the breakdown voltage of the zener diode ZD via the IN 4001 diode. When it is over (15V), the zener diode is turned on to turn on the LED of the photocoupler PC-2. At this time, the output of the PC-2 becomes LOW. (5) to send.

The data transmission unit 4 encodes the level signal of the circuit monitoring and fire monitoring by the digital controller, and level-forms it, converts it into a unique number of the presence / absence detection (7) (8) and transmits it to the serial interface. In combination with the next communication port (5) to transmit data.

Here, the control S / W can be used to control the circuit monitoring and fire monitoring circuits on and off.

The communication port 5 performs input / output communication management of the program of the MD-10MM chip inserted into the Bluetooth module 6 using RS-232. J1 can download the data of MD-10MM chip to the computer and modify it, and the modified data or program can be planted on the MD-10MM chip using J2's jack again.

The Bluetooth module 6 is a module for short-range communication of the MD-10MM chip, and audio input / output and data transmission / reception functions are concentrated.

The maximum communication distance is about 1KM, and I / O port for program input / output is also built in. The detailed functions are as follows.

When operating as a receiver, input the address according to the number of detectors. When a fire occurs or when a switch of a transmitter is operated, the wireless detector 8 receives through an antenna, and in the case of a wired detector 7, it receives through J3. Output data of designated address to Programmable I / O (PIC) to activate the following LCD and LED Driver to display character information on LCD and LED Dispaly to relevant wired / wireless detectors (7) (8) and The indicator on the transmitter lights up. In addition, the relay RY1 operates using a line buffer and an alarm is issued using a bell or buzzer.

At the same time, it performs a function to notify the person in charge, related organizations, etc. of the fire by text or voice.

The function of the repeater is to receive the signal of the wireless repeater or the wired repeater in another region, calculate bit check internally, and then transfer the output of the address number to the repeater or receiver using the antenna or relay (RY1) of J3.

The role of the transmitter is to use the built-in switch dedicated to the transmitter by using the function pin of the MD-10MM chip. This is because programming the address number on this function pin itself can make positioning easier without using a separate address number. In addition, the speaker and the microphone can be mounted in place of the telephone jack attached to the transmitter so that a single call button can function as a telephone.

In this way, the repeater, transmitter and receiver can be built as one integrated system, and the wired / wireless can be used in combination, making the installation of the fire alarm wireless transmitter easy, simple and free.
