7 is a flow chart showing the operation of the improved VMS remote control device according to the present invention, Figure 8 is a flow chart showing a process for controlling the VMS.

Referring to Figures 2 to 8 VMS remote control method according to the present invention will be described.

When power is applied from the power supply unit 200, the RTU 100 initializes the microprocessor 110, the data transmission / reception unit 120, the data conversion unit 150, and checks the operation state of each device (S100).

After performing the step S100 and initializes the operation state information and environment variables of the VMS stored in the memory (not shown) of the microprocessor 110 (S110), the sensor detects the operation state of the VMS (10) connected to the RTU (100) Detecting by using the (300) and stores the detected result in the memory (not shown) (S120) and determines whether or not the abnormality of the VMS (10) (S130).

In step S120, the door opening / closing detection sensor detects whether the door is open or closed, and whether the electricity supplied from the switching mode power supply (SMPS), that is, the VMS power supply of the VMS, is supplied to the VMS 10 from the SMSP detection sensor. The internal humidity of the VMS is detected from the humidity sensor. In addition, the line detection sensor monitors a line such as a disconnection of a dedicated line connected to the VMS, detects a power failure state of the power supply flowing into the VMS from the power failure detection sensor, and detects a power switch state (on / off) of the VMS from the switch detection sensor. do.

When an abnormality is detected in the operation state of the VMS 10 in step S130, the RTU 100 transmits the result data of detecting the abnormality to the operator system 20 (S131), and in step S130, If no abnormality is detected in the operation state, the sensor 300 which detects environmental information around the VMS is detected and stored (S140).

In step S140, the temperature of the VMS is detected from the temperature sensor, and the external illuminance of the VMS is detected from the illuminance sensor. Further, the wind direction around the VMS is detected by the wind direction sensor, and the wind speed around the VMS is detected by the wind speed sensor.

After performing the step S140, the RTU 100 detects data transmitted from the operator system 20 to determine whether it is a control command for controlling the VMS 10 (S150), and not a command for controlling the VMS 10. In the case of a command for requesting environment information around the VMS 10 by determining whether it is a command for requesting environment information around the VMS 10 (S160), the environment information around the VMS stored in a memory (not shown) (for example, Temperature, humidity, wind direction, wind speed, air pollution, Co2 concentration, etc.) is transmitted to the operator system (S161).

In addition, if the command transmitted from the operator system 20 in step S160 is not a command for requesting environmental information around the VMS, the RTU 100 determines whether it is a command for requesting an operation state of the VMS 10 (S170). In the case of a command for requesting the operating state of the VMS 10, the operating state information of the VMS 10 stored in the memory (for example, whether the door of the VMS is opened or closed, the SMPS of the VMS, the line monitoring connected to the VMS, and the power supplied to the VMS) Power failure state, power switch state of the VMS, etc.) is transmitted to the operator system (S171).

In addition, when the command transmitted from the operator system 20 is not a command for requesting operation state information of the VMS 10 in step S170, it is determined whether the command expresses data to the VMS 10 (S180) and the VMS 10. In the case of the command to express the data in the ()) receives the data transmitted from the operator system 20 (S181) and transmits the data to the field controller 12 (S183), the data transmitted to the field controller 12 is the electronic board ( It is expressed through 11).

In addition, when the format of the data transmitted from the operator system 20 is different from the data format of the field controller 12 in step S181, the format of the received data is determined by the field controller 12 in the data converter 150. The method may further include changing to a data format of S182. The step S182 converts when there is a difference in the data format and control scheme of the field controller 12 in the case of the VMS already installed.

On the other hand, in the case of the command for controlling the VMS in step S150, the microprocessor 110 determines whether it is an initialization command of the RTU 100 (S200) and returns to the step S100 in the case of the initialization command of the RTU 100.

In addition, when the command for controlling the VMS is not an initialization command of the RTU 100 in step S200, it is determined whether it is a command for initializing the VMS field controller 12 (S210) to initialize the field controller 12. The microprocessor 110 outputs an on / off signal to a reset terminal (not shown) of the field controller 12 connected to the digital output unit 160 (S211).

In step S210, when the command for controlling the VMS is not an initialization command of the field controller 12, the microprocessor 110 determines whether it is a command for initializing the VMS power 14 (S220) to determine the VMS power 14. In the case of the initialization command, the microprocessor 110 outputs an on / off signal to the VMS power source 14 connected to the digital output unit 160 to reset the VMS power source.

In step S220, when the command for controlling the VMS is not an initialization command of the VMS power source 14, the microprocessor 110 determines whether the command is for controlling a VMS internal fan (not shown) (S230). If the command to control the microprocessor 110 detects the temperature and humidity information of the VMS from the environmental information around the VMS stored in the memory (S231), and calculates the rotational speed according to the temperature and humidity to control the rotational speed of the fan Outputs a signal (S232) to control the rotation speed of the fan. In step S232, the rotation speed of the fan may be set in advance in a memory by setting a rotation speed value according to temperature and humidity.

In step S230, when the command for controlling the VMS is not a VMS internal fan control command, the microprocessor 110 determines that it is a VMS internal heater (not shown) control command (S240) to determine from the environment information around the VMS stored in the memory. The temperature and humidity information of the VMS is detected (S241), the internal temperature of the VMS according to the temperature and humidity is calculated, and a heater control signal is output (S242) to control the temperature of the heater. In step S242, the temperature of the heater may be stored in advance in a memory by setting a temperature value according to the temperature and humidity of the VMS.

As described above, the present invention has the advantage of being able to remotely control an already installed VMS field controller. In addition, in the event of a failure of the VMS, it is possible to control the VMS remotely without the support of field personnel, which has the advantage of easy maintenance and management.
