2. Description of Prior Art
With the rapid progress of biochemical technology, many biochemical equipments for time-consuming chemical reaction, biologic fermentation, microbe culture and separation purification have been developed. In order to efficiently monitor important values which may vary and affect the result, such as temperature, pressure, oxygen content and pH values, during the process of chemical reaction, biologic fermentation, microbe culture and separation purification actions, many biochemical equipments as shown in FIG. 1 are each provided with a plurality of detectors 11 to momentarily detect the above-mentioned important values for the user's reference. However, the action time of the aforesaid various actions is very tedious, and therefore it is difficult for the user to rivet his attention so that abnormal phenomenon can be momentarily noticed. Therefore, a warning device 12 (as shown in the functional block diagram of FIG. 1) is disposed on the biochemical equipment 10 to momentarily give a warning signal, for example, warning sound or warning light flash etc., when a predetermined abnormal phenomenon occurs, such as when the temperature is higher than a threshold value. Thus, the user may be informed to immediately take responsive measures to prevent uncurable errors occurring.
However, as the radiating range of warning signals is limited, the user's moving range is thus seriously restricted to cause inconvenience to the user. Accordingly, the main purpose of the present invention is to address this problem encountered in the prior art.

FIG. 1 is a functional block diagram of a conventional biochemical equipment;
FIG. 2 is a schematic view of a control system configuration in accordance with a first preferred embodiment of the present invention;

FIG. 4 is a schematic view of a control system configuration in accordance with a second preferred embodiment of the present invention.



DETAILED DESCRIPTION OF THE INVENTION
FIG. 2 shows a schematic view of a control system in accordance with a first preferred embodiment of the present invention. The control system is primarily applied to biochemical equipment 20 which takes a long time to react, such as chemical reaction equipment, biologic fermentation equipment, microbe culture equipment or separation purification equipment. The control system 2 primarily includes a detector 21, an abnormal state assertor 22, and a wireless signal emitter 23. A signal transmission channel 4 between the control system 2 and a computer 3 may be achieved by wired signal transmission or wireless signal transmission. Accordingly, the computer may receive, record and control the signal value outputted by the control system 2. The wired signal transmission may be accomplished by using the existing plug and play devices, such as USB, IEEE1394, LAN or CAN devices, and the wireless signal transmission may be accomplished by using Bluetooth, IEEE 802.11, IrDA communication or mobile signal communication means such as WAP (Wireless Application Protocol) and GPRS (General Packet Radio Service).
In order to efficiently monitor state variations during the reaction, the biochemical reaction equipment 20 has been furnished with various detectors 21 which include a temperature detector, a pressure detector, an oxygen content detector, a pH value detector, a whisking speed detector, a gas flux detector, a liquid level detector, a transfusion device detector, a valve ON-and-OFF detector, a power cut detector, a cell density detector, a gas detector, a slotware or pipeline breakage detector, a dextrose or sucrose detector or an online real-time analytical sampling device detector. The value detected by the detector 21, such as a temperature value, a pressure value, an oxygen content value, a pH value, a whisking speed variation control signal, a gas flux variation control signal, a liquid level variation control signal, a transfusion device control signal, a value ON-and-OFF control signal, a power cut responsive control signal, a cell density variation control signal, a gas concentration control signal, a slotware or pipeline breakage responsive control signal, a dextrose or sucrose variation control signal or an online real-time analytical sampling device control signal, is transmitted to an abnormal state assertor 22. The abnormal state assertor 22 presets respective normal value ranges corresponding to various kinds of values, such as the above temperature value, pressure value, oxygen content value, pH value, and so on. When one detected value exceeds a corresponding normal value range, the abnormal state assertor 22 transmits a corresponding abnormal signal to the wireless signal emitter 23. The wireless signal emitter 23 then sends a wireless signal to a portable alarm 24, and the portable alarm 24 gives a warning signal after reception, so that the user who carries with it may be informed. Accordingly, the user's moving range may be largely extended, thereby eliminating serious restriction and inconvenience. The wireless signal emitter 23 can be integrated into a computer 3 as well as the control system. Alternatively, the existing wireless transmission module of the computer 3 may be used to perform the wireless signal transmission function.
FIG. 3 is a schematic view of the portable alarm 24, wherein a warning signal generator 241 thereof gives a warning signal, such as sound, vibration or light flash, when triggered by the abnormal signal. A display 242 displays corresponding system abnormal information in response to the abnormal signal, such as when exceeding a normal temperature value range. An input device 243 is used for allowing the user to input instructions. A wireless control signal generator 244 communicates with the input device 243 and transmits a wireless control signal to the biochemical reaction equipment 20 in response to the instructions, so that the reaction action proceeded in the biochemical reaction equipment may be adjusted, and continuous occurrence of an abnormal state may be further suppressed by remote control, thereby eliminating the cause of warning signal presence.
The wireless transmission of the wireless signal emitter 23 and the portable alarm 24 may be accomplished by the existing wireless transmission architecture, such as Bluetooth, IEEE 802.11, IrDA communication, wireless call system, or mobile signal communication such as WAP and GPRS. The portable alarm 24 may be in the form of an existing mobile phone, a personal digital assistant, and so on.
FIG. 4 shows a schematic view of a control system in accordance with a second preferred embodiment of the present invention. The difference between the control systems of the first and second embodiments relies in the addition of an insertable and removable data storage device 25 (such as various flash memory modules). The insertable and removable data storage device 25 communicates with the detector 21 and the abnormal state assertor 22 for storing the data outputted by the detector 21 and the abnormal state assertor 22 and for allowing insertion and removal by the user. The data stored by the insertable and removable data storage device 25 is transmitted to the computer for storage via a signal transmission channel 4. The signal transmission channel 4 is identical to that of the first embodiment, and may also be achieved by wired signal transmission or wireless signal transmission. The wired signal transmission may be accomplished by using the existing plug and play devices, such as USB, IEEE1394, LAN or CAN devices, to support the plug and play function of the computer 3. The wireless signal transmission may be accomplished by using Bluetooth, IEEE 802.11, IrDA communication or mobile signal communication such as WAP and GPRS.
As described above, since the control system developed by the present invention and the monitoring device thereof perform the warning and control actions by means of wireless transmission, disadvantages encountered in the prior art are efficiently overcome and the main object of the present invention is thus achieved. The wired signal transmission channel is accomplished by existing USB, IEEE1394, LAN or CAN plug and play devices, which facilitates the insertion and removal actions of the user and thus eliminates the need for restarting the computer.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
