2 is a signal flowchart of a harmful gas transmission process according to the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an apparatus for transmitting a noxious gas according to the present invention.

As shown in FIG. 1, the apparatus for transmitting harmful gases according to the present invention includes a sensor module unit 10, a sensing data selection unit 20, a microprocessor 30, a wireless transmission module 40, and a power supply unit 50. Equipped.

The sensor module unit 10 is a CO sensor module 11, SO 2 The sensor module 12, the building material pollution sensor module 13, and the humidity and temperature sensor module 14 are provided.

The CO sensor module 11 senses CO gas existing in a corresponding underground space by using a CO sensor and transmits sensing data according thereto. SO 2 Sensor module 12 is SO 2 SO 2 in the underground space using the sensor The gas is sensed and the sensing data is transmitted accordingly. The building material pollution sensor module 13 detects polluted air (toxic gas, organic solvent) generated from building materials in the corresponding underground space by using sensors such as VOCs and transmits sensing data according thereto. The humidity and temperature sensor module 14 senses the humidity and temperature existing in the basement space using the humidity sensor and the temperature sensor and transmits the sensing data accordingly.

The sensed data selector 20 includes a transmit only selector and a receive only selector. The transmission-only selection unit transmits a command to transmit sensing data at predetermined intervals to each sensor module 11-14 of the sensor module unit 10. Accordingly, each sensor module 11-14 transmits the sensed data as described above at the predetermined period. In this case, the reception-only selection unit collects the sensing data received from the sensor module 11-14 at predetermined intervals and transmits the sensing data to the microprocessor 30.

The microprocessor 30 temporarily stores the various sensing data received from the sensing data selection unit 20 in a predetermined cycle in an internal memory and processes the sensing data into a predetermined form to reach a preset time point. 40). The microprocessor 30 has means for supporting various functions according to the type of each sensor provided in each sensor module 11-14 and the purpose of using a network node associated with the wireless transmission module 40.

The wireless transmission module 40 includes an RF module, a modem, and a MAC, and wirelessly transmits the various sensing data received from the microprocessor 30 to an external server when a preset time point is reached. .

An example of the RF module is Zigbee. The Zigbee is characterized by low cost and low power, and is suitable for short range wireless communication standardizing higher protocols and applications based on the standardized PHY / MAC layer of IEEE 80.215.4. Currently, Zigbee wireless communication chip which is widely used is Chipcon CC2420. The CC2420 is a RF transceiver chip of 2400 ~ 2483.5MHz band and has a DSSS modem function having a 250Kbps data rate. In addition, the Zigbee is capable of fast data transmission, can accommodate many network nodes, and has a relatively simple protocol structure. Since the Zigbee has a transmission distance of 150M, a data transmission rate of 20 to 250kbs, and a transmission / reception cycle is real time, it is possible to immediately transmit and receive sensing data in response to changes in pollutants.

The power supply unit 50 serves to supply a voltage required by each part of the harmful gas transmission device.

2 is a signal flow chart illustrating a noxious gas transmission process according to the present invention.

First, CO, SO 2 , building material pollution, humidity, and temperature existing in the corresponding underground spaces are sensed and transmitted at predetermined intervals using various sensor modules (S10).

The sensing data selection unit collects the sensing data sensed and received as described above at predetermined intervals and transmits the sensing data to the microprocessor (S20).

The microprocessor receives the sensing data received as described above from the sensing data selection unit, temporarily stores the sensing data, processes the data into a predetermined transmission format, and transmits the received sensing data to the wireless transmission module when the preset time point is reached (S30).

The wireless transmission module wirelessly transmits the sensing data received from the microprocessor to an external management server when a preset time point is reached (S40).

Therefore, the external management server receives and checks the sensing data transmitted as described above, and takes necessary measures (for example, a warning) when it is determined that the check result is abnormal, thereby allowing the user to respond appropriately. .
