Description
Technical field
The utility model relates to a kind of fungal culture chamber thermostatic control system power supply control circuit.
Background technology
In hospital clinical and medical research test, often need carry out operations such as fungi separation and Culture to the biological specimen that contains multiple fungi.Existing isolated culture method is to adopt manual mode; Sample is carried out necessary pre-treatment, and the sample streak inoculation after adopting inoculator to handle is again carried out separation and Culture to culture dish; So that the acquisition fungus colony, evaluation and the medicaments insensitive of further doing fungi detect.There is sizable drawback in this manual manipulation method, and it has following shortcoming:
(1) has certain communicable sample because operating personnel directly contact, cause infection easily, health of operators is constituted a serious threat;
(2) there is considerable human factor influence in operating process, thereby influences the quality of separation and Culture;
(3) the hand process is loaded down with trivial details, handles early stage to expend time in morely, and workload is bigger, and be unfavorable for sample with to work, thereby caused incuring loss through delay good cultivation opportunity, and then influence the separation and Culture quality.
Based on above deficiency, fungal culture chamber thermostatic control system arises at the historic moment, and fungal culture chamber thermostatic control system at present commonly used does not take power supply controlled measures such as protection in the power supply part; If sudden power, then system can't normally move, and very strict to the requirement of temperature in the picture Mycophyta separation and Culture process; Temperature is too high or mistake is low all can not obtain satisfactory product; In people or unmanned guard's process are arranged, if system cut-off can also in time be sought auxiliary equipment under the situation that the someone guards and supply power; If nobody sees that the rules system can only shut down wait; Often cause unfavorable conditions such as the fungi product of studying or producing necroses, variation in the process of outage, cause the product that can not get wanting, lose bigger.
The utility model content
The purpose of the utility model promptly is to overcome the deficiency of prior art, and a kind of fungal culture chamber thermostatic control system power supply control circuit is provided, and power supply is controlled protection; Guarantee system's normal power supply, other is provided with accessory power supply, still can operate as normal when guaranteeing system cut-off; Adopt the PLC three phase supply, can also carry out earth leakage protective, guarantee staff's personal safety; The utility model is simple in structure, and operating process is simple, adopts the automation mode to realize fungal culture; Reduce even eliminate the artifical influence factor of fungal culture process, reduce actual bodily harm, guarantee training quality operating personnel.
The purpose of the utility model realizes through following technical scheme: fungal culture chamber thermostatic control system power supply control circuit; It comprises that PLC controller, power supply detect relay J 3, at least three solid-state relay SSR1, at least three electric heaters, proportioning valve M, control system power supply, accessory power supply, and proportional valve control relay J 1, proportional valve control relay J 2;
Be serially connected in after control system power supply, the accessory power supply parallel connection on the three-phase out-put supply T of PLC controller; Described control system power supply comprises control system 220V power supply and control system 24V DC power supply; The three-phase out-put supply T of PLC controller, S, R through selector switch Q1 respectively with electric shock device KM1 in three pairs of normally opened contacts be connected; The control end of three pairs of normally opened contacts is serially connected with a solid-state relay SSR1 respectively in the electric shock device KM1; Each solid-state relay SSR1 goes up electric heater of serial connection; The other end parallel connection of three electric heaters; Be connected with an external circuit on any circuit between three pairs of normally opened contacts in selector switch and the electric shock device KM1, external circuit detects relay J 3 through resistance wire FS with power supply and is connected, and the control end of normally opened contact, proportional valve control relay J 2 interior normally opened contacts is serially connected in two outputs of proportioning valve M respectively in the proportional valve control relay J 1; The other end parallel connection of normally opened contacts in normally opened contact, the proportional valve control relay J 2 in the proportional valve control relay J 1, proportional valve control relay J 1,2 parallel connections of proportional valve control relay J and be attempted by on the power supply detection relay J 3 after proportioning valve M connect.
The beneficial effect of the utility model is: the utility model provides a kind of fungal culture chamber thermostatic control system power supply control circuit, has simple in structurely, and operating process is simple; Adopt the automation mode to realize fungal culture, thereby the artifical influence factor in reduction even the elimination fungal culture process reduce the actual bodily harm to operating personnel; Power supply is controlled protection, guarantee system's normal power supply, this practical information is provided with accessory power supply; Still can operate as normal when guaranteeing system cut-off, adopt the PLC three phase supply, can also carry out earth leakage protective; Guarantee staff's personal safety, guarantee advantages such as training quality.
