Abstract
The utility model discloses an alarm system for preventing wrong valve opening, which can effectively avoid production accidents. The alarm system comprises a controller, an alarm and a plurality of proximity switches, wherein the alarm and the proximity switches are respectively and electrically connected with the controller. In use, the proximity switches of the alarm system can be respectively installed on valves for controlling stock solution input quantity. When an operator approaches certain valve, the proximity switch installed on the valve can transmit a signal to the controller, and the controller judges whether to open the valve at the time point. If the controller judges that the valve shall be opened at the moment, the controller tacitly approves the signal. If the controller judges that the valve shall not be opened at the moment, the controller sends an alarm signal to the alarm so as to prompt the operator to select correct valve opening. The alarm system can effectively prevent liquid medicine preparation failure caused by wrong valve opening, and production accidents are avoided. The alarm system is applicable to popularization and application in the field of liquid medicine preparation equipment.
Description
Technical field
The utility model relates to soup dosing apparatus field, and especially a kind of valve that prevents is opened wrong alarm system.
Background technique
In the soup process for preparation, need multiple stoste be mixed usually, when preparation; In order to control the ratio of various stostes; All be provided with valve carrying on the pipeline of various stostes, through opening or throttle down is controlled the input quantity of various stostes, in addition; All there is strict restriction the opening time of each valve, reaches the requirement of regulation to guarantee the soup for preparing.At present, for the unlatching of valve or to close all be to adopt artificial mode to carry out, because the quantity of valve is more; And do not prevent accordingly that valve from opening wrong device, during artificial Open valve, be easy to occur out the phenomenon of wrong valve; Make and soup preparation failure cause the generation of production accident.
The model utility content
The utility model technical problem to be solved provides a kind of valve of effectively avoiding production accident takes place that prevents and opens wrong alarm system.
The utility model solves the technological scheme that its technical problem adopted: this prevents that valve from opening wrong alarm system, comprises controller, alarm and a plurality of near switch, said alarm, a plurality ofly is electrically connected with controller respectively near switch.
Further be that said is that photoelectric is near switch near switch.
Further be that said alarm is an audible-visual annunciator.
The beneficial effect of the utility model is: in use, and with being installed in respectively on the valve of control stoste input quantity of this alarm system, as operator during near some valves near switch; That installs on this valve can transmit a signal to controller near switch, and controller can judge whether to open this valve at this time point, should open this valve if judge this moment; This signal of controller acquiescence; Should not open this valve if judge this moment, then controller then sends alarm signal and gives alarm, and alert is chosen correct valve opening; Can effectively prevent to cause soup preparation failure, avoid taking place production accident because valve is opened mistake.
Description of drawings
Fig. 1 is that the utility model prevents that valve from opening the structural representation of wrong alarm system;
Description of symbols among the figure: controller 1, alarm 2, near switch 3.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, this prevents that valve from opening wrong alarm system, comprises controller 1, alarm 2 and a plurality of near switch 3, said alarm 2, a plurality ofly is electrically connected with controller 1 respectively near switch 3.In use, with being installed in respectively on the valve of control stoste input quantity of this alarm system, as operator during near some valves near switch 3; That installs on this valve can transmit a signal to controller 1 near switch 3, and controller 1 can judge whether to open this valve at this time point, should open this valve if judge this moment; Controller 1 this signal of acquiescence; Should not open this valve if judge this moment, then 1 of controller sends alarm signal and gives alarm 2, and alert is chosen correct valve opening; Can effectively prevent to cause soup preparation failure, avoid taking place production accident because valve is opened mistake.
In the above-described embodiment; Said can adopt near switch 3 passive various near switch, capacitive approach switch etc. near switch near switch, vortex type; As preferably; Said near switch 3 be photoelectric near switch, photoelectric near switch can discern effectively whether have operator near, recognition effect is better.In addition; Said alarm 2 can adopt existing various alarm; For example IR intrusion detector, buzzer etc. are that said alarm 2 is an audible-visual annunciator as preferred mode; Audible-visual annunciator can be pointed out operator from vision and the sense of hearing two aspects, can make operator promptly and accurately receive alarm signal.
Claims (3)
1. prevent that valve from opening wrong alarm system, it is characterized in that: comprise controller (1), alarm (2) and a plurality of, said alarm (2), a plurality ofly be electrically connected with controller (1) respectively near switch (3) near switch (3).
2. the valve that prevents as claimed in claim 1 is opened wrong alarm system, it is characterized in that: said is that photoelectric is near switch near switch (3).
3. according to claim 1 or claim 2 the valve that prevents is opened wrong alarm system, and it is characterized in that: said alarm (2) is an audible-visual annunciator.
