Long-range leakage monitoring system, based on internet refrigerant leakage early warning system and refrigerant leakage detecting device 110 structure
Frame and related setting, will describe in detail in terms of three below：
A1, the project data for consulting refrigeration system 100 manually, each reservoir equipment 101 is pre- in acquisition refrigeration system 100
Setting parameter, the level value K of refrigerant is (at the beginning of framework in volume V, reservoir equipment 101 of the parameter preset including reservoir equipment 101
During the beginning, level value is the beginning level value of reservoir equipment 101, that is, conventional level value), the diameter R of reservoir equipment 101, storage
The density p (being density of the refrigerant under the operating temperature of reservoir equipment 101) of refrigerant stored by liquid equipment 101, Yi Jichang
Number C (the immeasurablel refrigerant quality in reservoir equipment 101), current refrigerant total amount M in reservoir equipment 101 is set up with this
With the machine equation of level value K.
The parameter preset and machine equation of each reservoir equipment 101 in refrigeration system 100 are set to service manually
In device end 120, while also machine equation is set in data processing unit 112.It is appreciated that will only can be transported herein
Equation is calculated to set in data processing unit 112, and during parameter preset and machine equation all set server end 120,
One is that the monitoring of centralization, two are carried out to refrigeration system 100 because data processing unit 112 in order to pass through server end 120
Be mounted in the computer room of the side of refrigeration system 100, typically internal memory be not it is very big, present position nor very safe, not side
Just administrative staff are safeguarded, by unifying data resource to be saved in server end 120, and server end 120 is typically
It is arranged in the safe management computer room of comparing, the convenient internal memory that expands carries out the preservation of data resource and carries out data maintenance.Certainly

To in data processing unit 112, then data processing unit 112, can directly from local when refrigerant leak detection is carried out
Parameter preset these data resources are read, and without be read from server end 120 again, improves the treatment of data processing unit 112
Efficiency.
Wherein, machine equation is according to the different and different of the type of reservoir equipment 101, for example, work as reservoir
When equipment 101 is vertical Liquid storage container, the machine equation table of current refrigerant total amount M and level value K in vertical Liquid storage container
Show as follows：
M=V* ρ * K+C formula 1
When reservoir equipment 101 is horizontal Liquid storage container, current refrigerant total amount M and level value K in horizontal Liquid storage container
Machine equation be expressed as follows：
M=ρ * (R2* (2*acos (1-2*K)-sin (2*acos (1-2*K)))/8) * 4 formula 2
M in formula 1 and formula 2 is that current refrigerant total amount in vertical Liquid storage container or horizontal Liquid storage container, V are

If the corresponding reservoir equipment in system model sets up incidence relation；
Monitoring side sends access request to the server end；
The server end when the access request that the monitoring side sends is received, in response to the access request and the prison
Survey end and set up communication connection；
The monitoring side obtains the predetermined system model and shows after communication connection is set up with the server end, and base
Check the current refrigerant total amount of the reservoir equipment to monitor the refrigeration system in the predetermined system model of display
Refrigerant leakage situation.
10. method according to claim 9, it is characterised in that described that the storage is calculated according to the refrigerant liquid place value
The current refrigerant total amount of liquid equipment includes：
The refrigerant leakage detecting device obtains the type of the reservoir equipment and the parameter preset of the reservoir equipment, according to
The type selects the target machine equation of the type matching from preset machine equation, and according to the refrigeration
Agent level value and the parameter preset, the current refrigerant for calculating the reservoir equipment using the target machine equation are total
Amount, the parameter preset includes volume, the diameter of the reservoir equipment, the stored system of the reservoir equipment of the reservoir equipment
The density and constant of cryogen.
