Description

Electrophoresis power supply with additional functions

technical field

The utility model relates to an electrophoresis instrument power supply, in particular to an electrophoresis instrument power supply with additional functions.

Background technique

The electrophoresis instrument power supply with call recovery, small current maintenance and communication functions first appeared in foreign high-end power supply products. Their appearance was mainly outside the basic experimental functions of the electrophoresis instrument power supply, and gradually expanded following the experimental function requirements. Its appearance has greatly increased the intelligence of the power supply and facilitated the experiment. At present, with the development of the instrumentation industry, domestic electrophoresis instrument manufacturers have begun to explore adding these functions to the power supply of electrophoresis instruments, but the increase of these functions is closely related to the application of biological experiments, and is closely related to the internal design of power supply products. Manufacturers' understanding of functions is not clear or even misunderstood, and most of them are in the stage of exploration. Generally, in foreign countries, the power supply with incoming call recovery is generally selected and set on the power supply of the electrophoresis instrument at the beginning of the experiment. You can choose to have or not to increase the flexibility of the user. Generally, the default is the state of yes. Its function is generally realized through the inherent storage hardware circuit inside the power supply, and corresponding software is added on this basis. Some domestic manufacturers also want to realize the call recovery function in this way, but simply add the delayed shutdown function in the software, which not only fails to meet the functional requirements of the experiment, but also gives people the impression that the shutdown delay of the power supply is serious, basically function failure; this method also brings hidden dangers to cutting off the power input when the power supply fails. In foreign countries, the small current maintenance function is generally selected and set on the power supply of the electrophoresis instrument at the beginning of the experiment. You can choose whether to have it or not. Only a few domestic manufacturers have it. The communication function is composed of power supply and host computer software. Its function has a lot to do with recording variables and host computer software, and generally completes basic data communication and recording functions. The communication function is also relatively rare in foreign power supplies. Only one or two companies in the United States have seen such products, and it is rare in China. The communication function in foreign countries adopts wireless technology, and the upper computer software is closely combined with the experimental requirements, and its functions and technologies are relatively advanced. In China, there is generally only serial communication to complete the simple recording function.

The utility model has many practical functions close to the needs of customers, mainly as follows:

With call recovery function: when the electrophoresis power supply is in the normal working state, if the power grid fails, the instrument will return to the working state before the power failure after the call, and an alarm will be prompted. For the user, it is an option that has practical significance. For a short-term power outage that does not affect the experimental results, it can automatically continue to work after the call. For other power supplies, it is necessary to restart the experiment after power failure.

With small current maintenance function: after the electrophoresis power supply completes the work according to the preset program or time, it can maintain the work in the state of small current. For the situation that the experiment cannot be processed in time after the experiment, it can automatically maintain the low current working state to prevent the diffusion of samples in the electrophoresis zone and temporarily guarantee the experimental results.

Detailed ways

Now describe in detail the preferred embodiment of the utility model in conjunction with the accompanying drawings:

As shown in Figure 1, an electrophoresis power supply with additional functions such as power recovery, small current maintenance, and communication is composed of the following parts: 1. Hardware circuit, 2. Machine control software, 3. Computer software system. The following is a detailed description of its structure and composition by function, and a brief description of its use.

The composition and use of the incoming call recovery function are relatively complicated. Its structure is composed of hardware circuits and machine control software. The hardware circuits are composed of voltage references, precision resistance-capacitance circuits, and memory. The software is mainly the control software of the machine. Including selection software, detection software, storage software and so on.

The incoming call recovery function must be set at the beginning when it is used, and then enter the setting "function setting interface". Select "ON" or "OFF" of the incoming call recovery function, and press [OK] to make it take effect. When you select "On", press the [Enter] key, the interface prompts: Incoming call recovery is enabled; when you select "Off", press the [Enter] key, the interface prompts: Incoming call recovery is off; the factory default setting is off. When it is set to off, if the power-off time is less than 8s, it can be restored to the operating state before power-off, and continue to run; if the power-off time is greater than 8s, it will not return to the operating state before power-off, and enter the "power supply operation interface". The operation interface of the power supply is shown in Figure 2. When it is set to "Start", no matter how long the time is, it can always return to the running state before the power failure and continue to run; there is a "!" prompt in the lower right corner of the screen.

In this way, not only can you choose whether to set or not on the power supply of the electrophoresis instrument at the beginning of the experiment, but also have an automatic judgment function and automatically control its function when it is not set, so that it is more in line with actual needs and has greater flexibility. sex, making it more human.

The small current maintenance function is mainly composed of power devices plus corresponding program setting and control parts. The specific current value can be divided into two types: settable and automatic. The small current maintenance function is mainly complicated and important in the experimental experience and software control part.

The small current maintenance function must also be set before use, and then enter the setting "function setting interface". Select "On" or "Off" of the small current maintenance function, and press [Enter] to make it effective. The lower right corner displays " " indicates that it is effective. When this function is running, the buzzer will alarm, and the added alarm prompt makes the power supply more safe and humanized.
