For the control system of low temperature memory device
Technical field
The utility model relates to a kind of low temperature memory device, particularly a kind of control system for low temperature memory device.
Background technology
Along with the develop rapidly of the sophisticated technologies such as mankind's biotechnology, medical skill, people are also more and more for associated materials (virus, germ, red blood cell, leucocyte, skin, bone, the bacterium etc.) demand of scientific research, the environmental requirement of preserving is also more and more higher, with and the factor such as the difficulty obtained, make its personal value also more valuable than gold, chronicity and the stability of therefore it being preserved to environment seem of crucial importance.Generally to utilize medical ultra low temperature freezer storage previous materials at present.But existing medical ultra low temperature freezer often can be paralysed because sensor fault causes control system, and then cannot provide preservation environment steady in a long-term for consumer products.
Utility model content
The purpose of this utility model is to provide a kind of control system for low temperature memory device, and it can ensure the operation steady in a long-term of low temperature memory device, thereby overcomes deficiency of the prior art.
For realizing aforementioned goal of the invention, the utility model has adopted following technical scheme:
A kind of control system for low temperature memory device, comprise monitoring sensor unit and the main control unit of temperature in low temperature memory device, described sensor unit is connected with main control unit, wherein, described sensor unit comprises at least one master reference and at least one backup sensors, and described master reference and backup sensors are connected with main control unit respectively.
Further, described control system also comprises display unit, and described display unit is connected with main control unit.
Further, described control system also comprises alarm module, and described alarm module is connected with main control unit.
Further, described alarm module comprises sounding and/or luminous alarm equipment.
Further, described alarm module comprises hummer or warning lamp.
Further, described main control unit is also connected with remote communication module.
Further, described remote communication module and remote alarms equipment connection.
Further, described low temperature memory device is medical ultra low temperature freezer.
Compared with prior art, the utility model at least tool has the following advantages: improve by the control system structure to low temperature memory device, can effectively improve the reliability of equipment, for user provides the enough emergency processing time, thereby reduce the probability of bringing direct economic loss because of equipment failure to user.
Accompanying drawing explanation
Fig. 1 is the control system block diagram in order to medical ultra low temperature freezer in the utility model one preferred embodiment;
Description of reference numerals: 1-master reference, 2-backup sensors, 3-control display screen, 4-hummer, 5-control mainboard, 6-remote alarms equipment.
Embodiment
Below in conjunction with a preferred embodiment and accompanying drawing, the technical solution of the utility model is further described.
As previously mentioned, in view of the deficiency of existing low temperature memory device control system, the utility model is intended to propose a kind of new control system that can effectively promote low temperature memory device operation stability.
Particularly, the technical solution adopted in the utility model mainly comprises: form sensing unit at the multiple sensors of set-up of control system, in the time that wherein a sensor exists fault, can switch to another sensor and work on, to avoid control system paralysis.
Further say, also can in control system, set up alarm module, in the time that sensor breaks down, can send sound and light alarm by main control unit control alarm module, prompting user sensor fault, so that user carries out emergency processing in advance.
Consulting Fig. 1 is a preferred embodiment of the present utility model, it relates to a kind of control system that is applied to medical ultra low temperature freezer, comprise and control mainboard 5 (also claiming " main control unit "), sensor unit, control display screen 3 (also claiming " display unit ") and alarm module, this sensor unit, control display screen 3 and alarm module are all connected with control mainboard.Wherein, this sensor unit comprises a main temperature sensor 1 (being called for short " master reference ") and a backup temperature sensor 2 (be called for short " backup sensors ", also claim " secondary sensor ").This alarm module comprises hummer 4.
Preferably, also can on control mainboard 5, PORT COM be set, and utilize this PORT COM and supporting remote communication module and remote alarms equipment connection.
In the process of this control system real work, in the time that main temperature sensor breaks down, control mainboard and can automatically change and provide feedback temperature by secondary sensor, normally work to continue control system.Control the printed words that can show " sensor fault " on display screen, and hummer can send the interruption prompt tone of " ticking ", by inform user malfunction situation with upper type, so that user can formulate emergency plan in time, reduce or avoid loss.And this state can remain to user and find fault always, and could stop by operation.
When the new control system that the utility model provides has overcome existing equipment key components temperature sensor fault, equipment is the deficiency of cisco unity malfunction, make user obtain the valuable emergency processing time, relatively improve equipment dependability, reduce or avoid the direct economic loss of company, and cost is low, it is easily convenient to implement.
It is to be noted, although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in instructions and embodiment, it can be applied to the various fields of the present utility model that are applicable to completely, for those skilled in the art, can easily realize other modification, therefore not deviate under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
