The disclosure provides a method for monitoring a short-term voltage stability of a power system. The method includes: obtaining a topology and time series of a current power system; inputting the topology and the time series of the current power system into a trained spatial-temporal graph network model, the trained spatial-temporal graph network model being obtained by classification learning on a spatial-temporal graph network model based on a simulation sample dataset; outputting a status of the short-term voltage stability of the power system; and sending an alarm signal in response to outputting an unstable status of the short-term voltage stability of the power system.

Disclosed is an interconnected transportation network system, wherein same is related to the field of transportation facilities and control, and comprises a main transportation system, a transfer system and an entry/exit system. The main transportation system is formed of a closed annular rail vehicle, and the annular train moves continuously on a T-shaped track to fulfil a passenger transportation task by means of multi-point drive. The transfer system (intercommunication) is of the same structure as that of the main transportation system, and the passengers transfer between main transportation lines by means of the transfer system. The entry/exit system (terminal) is formed of an annular buffer vehicle system and a stepping speed control system, and the passengers enter or exit the main transportation lines in a self-service manner by means of the entry/exit system.

The present disclosure relates to compensating method for cell assembly. According to a deviation value of a key position of a measured array substrate, a compensation value of an exposure parameter of black matrix process of a color film substrate is calculated in real time by using historical measurement data of batches. The compensation value is fed back to a manufacturing apparatus in real time. The manufacturing apparatus corrects the key parameter of the apparatus timely according to the compensation value of the exposure parameter of the black matrix, to manufacture a color film substrate matching with the array substrate.

A wearable filtrating artificial kidney device, comprising a transfusion inlet (), a blood pump (), an arterial pressure detector (), a blood filter (), a venous pressure detector () and an air detector (), wherein the transfusion inlet (), the blood pump (), the arterial pressure detector (), a resin hemoperfusion apparatus (), an active carbon hemoperfusion apparatus (), the blood filter (), the venous pressure detector () and the air detector () are connected sequentially; a liquid waste outlet of the blood filter () is connected with an ultrafiltration control pump (). Glomerulus filtration can be simulated to achieve the goal of removing toxins and excessive moisture in the blood by virtue of ultrafiltration of the blood filter (). A dialyzate and a complicated dialyzate circulating device are not used for the device, so that the volume and weight of the device can be reduced greatly, and the device can be worn conveniently. The device is simple in structure, easy in operation and low in cost.

Wearable filtrating artificial kidney device

The present invention provides a production equipment monitoring method and system, and the method comprises: receiving production equipment alarm information; determining abnormal production equipment according to the production equipment alarm information, and determining a user group corresponding to the abnormal production equipment according to preset correspondence between production equipment and user group; and sending the production equipment alarm information to a user in the determined user group in a preset alarm manner. As a result, alarm information can be sent to the corresponding user(s) in the preset alarm manner the first time an abnormity in the production equipment is found, so as to notify related personnel to handle the abnormity timely and accurately.
