> The medicine stores in a storehouse the
monitoring technology plan
The GSP standard to aspect and so on storehouse area,
equipment facility, control system all proposed the concrete explicit
request, regarding the GSP inspection unqualified enterprise, the
country adopts a ticket veto system, does not allow to enter the
medicine profession. For example, the GSP standard requests "the
enterprise in the hardware aspect to be supposed according to the
management scale establishment corresponding warehouse, its area (for
floor space) the major industry should not be lower than 1,500 square
meters, the medium enterprise should not be lower than 1,000 square
meters, the small business should not be lower than 500 square meters;
The enterprise has is suitable the drugs classification to take
care of and to conform to the drugs memory request storehouse.
Normal temperature storehouse is 0 - 30 degree Celsius;
The cool storehouse temperature is not higher than 20 degree
Celsius; The cold storage temperature is 0 - 10 degree Celsius;
Various storehouses relative humidity should maintain at 45% -
between 75% ". And has the request to have uses in flammable
explosive, to be virulent the safety equipment which and so on under
the environment operates and warm, the humidity regulation equipment.
Design thought:
According to the customer request and the scene situation,
Beijing triumphantly controls the technical limited company to select
the current industry observation and control popular DCS method,
namely the collection measurement system, designed a set in view of
the medicine production, the circulation profession has stored in a
storehouse the management the synthesis supervisory system.
The supervisory system core is based on inserts the type system
to touch the screen control computer, it has 5.7 "the colored LCD
demonstration and the rich data acquisition, the control as well as
the correspondence connection, coordinates the inexpensive sensor and
the execution may constitute a complete supervisory system, through
correspondence connection and so on the ethernet may with on position
business management system software connection, the business
management system be allowed to carry on the data inquiry, the control
to the supervisory system.
Touches the screen control computer is uses the industry control
technology research and development to become, can 24 hours non-stops
run, guarantee the data acquisition, controls uninterruptedly.
Uses the inexpensive standard connection sensor, greatly saves
the system cost, the sensor and the main engine installs the distance
to be possible to amount to 1.2 kilometers, is easy to maintain and
the replacement sensor.
Implementation plan:
Each storehouse provides to touch the screen main engine, each
main engine are most may connect 255 sensors. The sensor
quantity is short to 8 may directly use the standard 4-20mA sensor
direct company to receive the main engine, saves the system cost, more
sensors need to use have RS485 the sensor to connect the
correspondence main line.
The sensor may wilfully select the warm humidity, the water
immersion, infrared, 门禁, the window broken, the voltage, the
electric current sensor, realizes warm monitoring function and so on
humidity monitoring, waterproof monitoring, safe monitoring, electric
power security.
Touches warm humidity record, monitor routine which the screen
main engine movement may have custom-made, can the real time display
parameter, insert the type database to carry on the record to the
parameter, demonstrated the parameter change curve, the position
business management system may to control the main engine through the
ethernet mouth on the data to carry on the inquiry.
May establish in the warm humidity the lower limit, 越限 when
through way and so on sound, light, short note carries on the warning.
May to equipment and so on in storehouse ventilating fan, air
conditioning, light carry on the monitoring, appears when the
breakdown carries on the warning, and according to the strategy which
establishes to these equipment carries on the control.
May establish the parameter recorded time gap.
Timed control function: May defer to the season, day and
night and so on the condition, to the warning at equipment and so on
lower limit parameter and ventilating fan, air conditioning, light
carries on the control.
The configuration design, facilitates the expansion control
function.
System performance parameter:
Input signal: 4-20mA standard sensor signal
RS485, RS232, ethernet correspondence signal
Does the pitch point input signal
The recording capacity is bigger than 100,000 records.
This system may widely apply to the industry, the agricultural
research, the meteorology, the environmental protection, the hygienic
guard, the medicine, stores in a storehouse domain and so on
transportation, museum, laboratory, greenhouse.
