A method for detecting blood component in a sample comprising reacting a human erythrocyte membrane band 3 glycoprotein (band 3) in the sample and a hemagglutinin produced by a microorganism belonging to the genus Conidiobolus (CA) and measuring said band 3 glycoprotein contained in a complex produced by the reaction. Because band 3 can be detected specifically, at high sensitivity, and stably by the use of CA, the method ensures qualitative or quantitative, and accurate detection of human blood component in feces or contents of digestive organs, of which the determination of the presence or quantity of human blood component by hemoglobin is difficult.

In an image forming apparatus according to the present invention, a software portion incorporated in the apparatus is provided with a virtual case storage portion 12, to previously create virtual cases by a virtual case compiler 16 outside of the apparatus and store the virtual cases. Fault diagnosis is made by comparing fuzzy qualitative values into which the values of sensors are converted on the basis of fuzzy membership functions with the virtual cases. If a fault is diagnosed as a result of the comparison, repair operations for repairing the fault are read out from a work script table 15. In this case, operation information for repair are stored to correspond to each of a plurality of domains into which a state space which the apparatus can take up is divided. Accordingly, it is possible to correctly read out corresponding repair operations from the work script table 15 depending on which of the domains is a domain to which the present state of the apparatus belongs. As a result, a self-repair system can be constructed as a practical built-in type system, thereby to make it possible to reduce the scale of the system related to the fault diagnosis as well as to reduce time required for the fault repair.

In an image forming machine, an objective model storage device stores parameter data that represent elements of the machine and relationships among such parameters, and parameter membership functions, and fault diagnosis knowledge. A degradation storage device stores a fuzzy qualitative value for a parameter changed by degradation of an element of the machine. Preferably, degradation indicative data are converted into fuzzy qualitative values, and the value of the parameter changed by degradation is represented by a fuzzy qualitative value. The machine includes sensors for sensing functional states thereof, and providing state data representative of such states. The state data sensed by the sensors are converted into fuzzy qualitative values. Then, a fault judgement device determines whether or not a fault exists by comparing the obtained fuzzy qualitative values with the parameter data stored in the objective model storage device. If the fault judgement device determines that a fault exists, a fault diagnosis device performs fault diagnosis by utilizing, as an initial value, the value of the parameter changed by degradation. A specification device specifies fault causes by comparing the result of the diagnosis with the state data which was converted into the fuzzy qualitative values. Then, a repair device operates actuators of the machine to overcome the specified fault.

A system according to the invention has a plurality of sensors, a system control circuit and a plurality of actuators. State data, supplied from the sensors, is compared with characteristic data in the system control circuit. From this comparison, it is judged whether a fault has occurred depending upon whether the state data is relatively lower or higher. If a fault has occurred, fault inference fault is made on the basis of a comparison between qualitative data and fault diagnosis knowledge which are stored in the system control circuit. Then a judgement is made as to which of the elements in an image forming apparatus is abnormal. An actuator operating signal thereafter is generated as a result of this judgement.

A simulation system is provided which is capable of simulating the behavior of a sheet transported by a transportation system. In response to application of a control sequence formulated for the sheet transportation system, a simulation is performed to check how the sheet is to be transported in the sheet transportation system on the basis of the applied control sequence. Necessary data are extracted from hardware systems constituting the real sheet transportation system. On the basis of the extracted data, a virtual sheet transportation system is constructed in a computer, and the sheet is represented by information indicative of the locations of opposite ends of the sheet and the distance therebetween. The sheet thus represented is moved by a predetermined unit distance in the virtual sheet transportation system on the basis of the control sequence, and data is computed for every movement of the sheet.

An image forming apparatus has a functional redundancy system by which an inherent function normally performed by a certain portion is performed as a potential function by another portion, when such certain portion no longer can be perform its inherent function. In a first operative sequence, portions in the image forming apparatus perform their respective inherent functions. However, where a function of a certain portion in the apparatus is lost, for example, where a fault occurs and a particular element has failed, operation of other portions in the apparatus are controlled according to a second sequence. In the second sequence, the inherent function of the portion which has failed is replaced by the potential function of another portion in the apparatus.

The system of the present invention has a plurality of sensors 1a, 1b and 1c and a system control circuit which includes a case memory portion and a work script memory portion. In response to application of state data from the sensors 1a, 1b and 1c, the system converts the state data into symbolic data. Then the symbolic data is evaluated to judge whether or not a fault exists and to specify a fault symptom. As a result of the judgement, a fault symptom and a fault in the objective machine are determined. Thereafter, cases stored in the case memory portion are retrieved on the basis of the results of the fault diagnosis and a fault simulation. A case which closely resembles the present state of the objective machine is selected. Then, repair work described in the selected case is executed.
摘要:
The present invention makes it possible to make good self-repair on which little secondary effect is exerted by calculating a manipulated variable of a parameter at the time of the repair by a functional amount in an image forming apparatus having a self-repair function. When a fault occurs, control-type repair for operating a physical parameter is first made. In this repair, the physical parameter to be operated is searched for (n3). If the physical parameter to be operated is determined, a manipulated variable of the physical parameter is then calculated by a functional amount (n4). The manipulated variable of the parameter by the functional amount is determined by adjusting the degree to which a plurality of functions are developed. Therefore, a manipulated variable in which the development of the functions is most preferable as the entire apparatus is determined. If the fault cannot be repaired by the control type repair, functional redundancy type repair is made (n6, n7, n8, n9). In the functional redundancy type repair, priorities to repair candidates are determined by the functional amount.
摘要:
A method of automatically creating control sequence software required for a machine system controlled by a computer includes four algorithms, that is, "derivation of control sequence specification".fwdarw."derivation of a qualitative control sequence".fwdarw."addition of quantitative information (derivation of a quantitative control sequence)".fwdarw."generation of a C program". The qualitative control sequence is a state transition matrix following the time sequence. This qualitative control sequence is derived by making use of a qualitative inference system. A quantitative control sequence is obtained by adding quantitative time between states to the qualitative control sequence. Time information is calculated on the basis of design information of a machine portion stored in a design information database. As a result, it is possible to reduce the manual burden on the software development by using the present invention.
