Or open the door lock.

The first wireless communication unit 120 is composed of a Zigbee communication module consisting of one chip, or a B-CDMA (Binary CDMA) modem.

The ZigBee communication module according to the present invention is one of the representative technologies of a short range wireless sensor network having low power, low cost, and ease of use, based on the PHY layer and MAC layer of the IEEE 802.15.4 standard. It is a standardized technology, which can be used for more than one year even with a typical battery, and the transmission speed is up to 250 Kbps in the 2.4GHz band, and the transmission distance is 10 to 75m range, 75m / 1mW (0dBm) or less, and 30mA It is TX and can be used for 2.4m hardware up to 30m / indoor, over 100m / outdoor, and can attach up to 65,536 nodes to the network, Star, Cluster Tree and Mesh network. Even features are supported.

In addition, the first wireless communication unit 120 may be configured as a B-CDMA (Binary CDMA) modem.

The B-CDMA (Binary CDMA) modem used in the present invention is an external input / output device of a fire detection system, which maintains a constant envelope of an external A / V signal through multiple codes. To keep the constant constant, noise is generated during the truncation of the transmitter to a finite value, and minimizing the noise has a great effect on improving performance. In addition, chip error is caused by additive white noise while an external A / V signal is being transmitted.

To accurately analyze these noises, the noise generated by truncation can be found by approximating Gaussian since the distribution of multiple code signals follows the Gaussian distribution when the number of codes is large.

In addition, the noise caused by the PSK modulated chip can be approximated to Gaussian after despreading if the spreading factor is large and the autocorrelation property of the code used is good. The above two approximations can theoretically analyze the B-CDMA performance.

The B-CDMA used for the first wireless communication unit 120 includes a PW-CDMA for converting the size of the truncated signal to the width of the signal, an MP-CDMA for converting the phase of the signal, and a code for transmission bits. Any one of CS-CDMA transmitted through MP modulation is selected and configured. The B-CDMA according to the present invention is configured as an MP-CDMA system for converting to a phase of an external A / V signal.

That is, a signal summed using multiple codes has a large peak to average power ratio (PAR), and the greater the number of codes used, the more serious it becomes. At this time, the MP-CDMA according to the present invention cuts the signal to a finite value and then PSK modulates it. The envelope is constant because the PSK modulated signal differs only in phase. The receiver detects the PSK modulated chip, inverts the phase of the signal to the magnitude of the external signal, and detects the transmitted bit in correlation with the code.

Through this process, the envelope of the external A / V signal flowing through the multiple codes is kept constant and transmitted to the internal control means and the voice warning unit.

In addition, a B-CDMA modem is classified into a low speed B-CDMA and a high speed B-CDMA.

The low speed B-CDMA network consists of Point-to-Point, Point-to-Multipoint, and Broadcasting. Up to 16 links are connected in close proximity, and the data rate is 800 Kbps in TDMA mode. 270Kbps in CDMA mode, using 2402 ~ 2480MHz ISM bands, maximum output is 20dbm, output control is 4dB 8 Steps, low power operation is 2.8V ~ 3.3V, reception sensitivity is -85dBm typ.

 High-speed B-CDMA becomes channel allocation (10/5) when the transmission rate is 6Mbps / 12Mbps, and channel allocation is bandwidth (7MHz / 14MHz), and the frequency used is 2.4000GHz ~ 2.4835GHz ISM bands, and B-CDMA Through modulation, it has high spectral efficiency, strong against interference by using CDMA characteristics, low power consumption by using nonlinear amplifier, and has the characteristics of maintaining transmission rate corresponding to WLAN.
