Description
Technical Field
The invention relates to the field of ship dosing, in particular to a marine automatic and accurate control dosing system and method.
Background
At present, in industrial occasions requiring protective dosing, such as ships and the like, the liquid medicine is required to be prepared on site and distributed to each user. In a marine water pipe system of a ship, marine life protection is required for the marine water pipe system by electrolyzing seawater on site to generate a sodium hypochlorite solution, distributing the sodium hypochlorite solution to each user, and performing marine life protection on the marine water pipe system by using marine life protection medicines. The current distribution method of the dosage of users mainly adopts the manual or semi-automatic adjustment of the liquid medicine inlet valve of each user. If a set of pharmaceutical units supplies a plurality of drug protection users, the dosage of the users can change along with the production requirements, the dosage of the users in different states such as starting, stopping, peak value and the like, and the total dosage requirement can change along with different combination modes of the users. The dosage of a user can deviate from a set numerical value, the distribution valve of the user needs to be manually or semi-automatically adjusted, and in the adjusting process, the dosage is difficult to accurately control due to the fact that the opening degree of the valve is changed among users, the total output of the pharmaceutical unit is not changed, the valves are mutually interfered.
In the case of a ship or the like requiring industrial administration, for example, a marine anti-marine organism device, sodium hypochlorite generated by electrolyzing seawater is administered as an anti-marine organism drug to a user of a seawater system to prevent marine organisms from living in the seawater system. When the number of users to be administered is large and the usage of the users needs to be changed, the usage of the liquid medicine changes every time the user combination changes, for example, when a new user is put in or the user who originally runs stops working. The variation may induce disturbance to the dispensing amount of other users, so that the dosage of other users deviates from the set dosage, and the protection effect of the liquid medicine of other users is affected.
In the existing application occasion of using liquid medicine for tube medication, a common method is to mark on a valve disc of an entrance valve of each user, and if the number of users is small, the marks are fewer and easy to mark; if a plurality of users exist, the combination mode reaches dozens, the marks are increased, and dozens of marks are needed on one valve disc and basically impossible. The total required dose of the user is also difficult to match with the drug throughput, if the total drug throughput is not constant.
In the control mode of dosage in production, the semi-automatic dosage control adopts a control mode that an electromagnetic valve is matched with a user home-entering valve combination. This mode of adjusting the dosage amount control may be used if there are fewer users to administer the drug. If the number of administration users is large and the dosage of each user is changed, a huge number of valve groups are needed to be equipped, and the number of the valve groups is in a mathematical quadratic order. For example, if there are 7 users, each with three doses, acting together with a maximum amount of peak administration without consideration of a wrong peak administration, 99 combinations are required;
if the peak dosage is required for the dosage application, the pharmaceutical unit needs to cover the peak dosage of all the combinations, the pharmaceutical capacity needs to be large, the volume and weight of the pharmaceutical unit are increased, the large space in the ship or the factory is occupied, and the purchase cost of the pharmaceutical unit is increased.
