- the DAS may include a control unit for performing the control function described in the present specification describing the present invention.
- the DAS according to the present invention is installed on one side of the worker, receives measurement information from a measuring instrument (not shown) installed in the workshop, and converts the received analog data into digital data having the same standard as shown in FIG. It transmits to DB (monitoring server).
- DB monitoring server
- the instrument includes all instruments that are the basis for managing HSE (HEALTH, SAFETY, ENVIRONMENT) of the workplace.
- the measuring device installed in the workplace transmits the measured value to the DAS through sensing for each cycle, and the communication between the measuring device and the DAS is performed based on Zigbee communication.
- the DAS receiving the measurement information of the instrument transmits it to the DB (monitoring server) based on Wi-Fi and LoRa communication.
- the DAS includes a Zigbee communication module, a Wi-Fi communication module, and a LoRa communication module.
- the communication unit receives measurement information from the instrument through the Zigbee communication module, and communicates with the DB (monitoring server) through the Wi-Fi communication module and the LoRa communication module.
- the DAS may further include an A/D converter for converting the measurement information, which is an analog format, into a digital format.
- the data transmitted to the DB by communicating with the DB (monitoring server) through the Wi-Fi communication module and the LoRa communication module is data converted into a digital format through the A/D conversion unit.
- the monitoring server when the above-described DB, that is, the monitoring server receives data from the DAS, it can be configured to output a response signal to the reception.
- the DAS further includes a response signal receiving unit to receive the response signal of the monitoring server. And after transmitting data to the monitoring server through the communication unit, the DAS further performs a function of determining whether there is a response signal received from the monitoring server through the response signal receiving unit for a predetermined time, which further includes a response signal reception determining unit in the DAS to make it function.
- the DAS if the response signal is not received from the monitoring server through the response signal reception determining unit, this means that communication between the DAS and the monitoring server is not properly made, so it functions to switch the communication.
- the communication switching unit is to convert the communication to be made to the secondary communication instead of the primary communication communicated between the DAS and the monitoring server for the first time. For example, when LoRA communication is the main communication, If there is an error, the communication method is switched to the secondary communication, Wi-Fi communication.
- the DAS according to the present invention may be configured as shown in [Table 1].
- the DAS according to the present invention forms a recess formed concave on one surface with respect to a predetermined box shape.
- a support is configured in the groove, and any one of a Wi-Fi communication module or a LoRa communication module may be installed on the upper surface of the support.
- the cover and support are located on the upper side of the support, and the other one of the Wi-Fi communication module or the LoRa communication module can be installed on the upper side of the cover and the support. have.
- the height of the groove portion of the DAS is higher than that of the state in which the above-described communication module is installed on the cover and support in addition to the height of the support and the cover and support.
- the cover and support may have a shape of ' ⁇ ', and the communication module located on the upper surface of the support is located in the inner region according to this shape. Therefore, it is preferable that the inner height of the cover and support has a height sufficient to accommodate the communication module located on the upper surface of the support.
- the support is guided along a rail formed on the upper surface of the groove to be inserted into the groove or exposed to the outside of the groove.
- a groove having a multi-stage shape of ' ⁇ ' is configured, and among the lower surfaces of the support, one side of the lower surface in contact with the rail is a guide having a multi-stage shape inserted into the groove of the rail. bumps are formed.
- the support is not separated in a direction other than the guide direction and can be guided.
- the shape of these rails and guide protrusions may be adopted conventionally, and may be changed by adopting the configuration of all rails that can be pulled or pushed by other human forces.
- the above-described rail may be formed on one side of the upper surface of the support, which is in contact with the lower surface of the cover and support. That is, according to this, the guide projection corresponding to the rail of the support is also formed on the lower surface of the cover and support.
- a sealing rod and a pulling rod are formed at the rear of the support.
- the sealing rod is composed of a cylinder and the end thereof is fixedly connected to the cover and support.
- the pulling rod has a 'L' shape, and one end is connected to the lower surface of the sealing rod, and the other end is made to form an adhesive means.
- the bonding means may be an air cap, Velcro, or the like, so that the other end of the pulling rod can be fixedly connected to the base by the bonding means.
