The present invention discloses a blockchain-based federated modeling method, device, device, and storage medium. The method includes: when the number of training clients detected reaches a preset number, the training initiator corresponds to The client information releases configuration information to each training client; the training initiator uploads the model to be trained to the main chain; the training initiator determines the target model based on the aggregation gradient and the model to be trained. The invention realizes the modeling of federated learning through the block chain. Under the premise of protecting the privacy of federated learning data, it has no impact on the accuracy of federated learning, improves the training effect and model accuracy of federated learning, and does not need to modify the gradient in transmission. Modification of model parameters such as gradients achieves a balance between privacy protection of model parameters such as gradients and model convergence or model accuracy; it can completely prevent information leakage and improve the security of data samples in federated learning.

An electronic clinical thermometer includes a control circuit (4) which controls operation timing according to the operations of a measurement device (3) and a notification device (9) so that the measurement operation and the notification operation will not be performed simultaneously, thereby preventing lowering of the measurement accuracy due to battery voltage lowering. The electronic clinical thermometer (1) includes the measurement device (3) for measuring a body temperature, a drive device (8) for recording the notification data, the notification device (9) for performing notification by a drive signal formed according to the notification data, and the control circuit (4) for controlling the measurement operation and the notification operation. The control circuit (4) performs control so that the operation timing of the measurement device (3) is shifted from the operation timing of the notification device (9) according to their operation states so as to prevent simultaneous operations of the measurement and notification. Thus, in the electronic clinical thermometer performing notification operation, it is possible to prevent simultaneous execution of the measurement operation and notification operation, which in turn prevents measurement accuracy lowering due to battery voltage lowering.

The embodiment of the invention discloses a barrage display method, device and electronic equipment. The method in the embodiment of the present invention includes: defining a List collection; constructing a Map variable, constructing the mapping relationship between the textview control of the bullet chat and the unique identifier of the bullet chat in the codeToTextView collection of the Map variable; obtaining the user's bullet chat display setting instruction ;According to the instruction, take out all the target unique identifiers corresponding to the currently displayed bullet chat textView controls from the List collection, and find the corresponding target textView controls through the target unique identifiers; obtain the target textView control currently in the bullet chat container object Height position information; adjust the height position information of the target textView control in the bullet chat container object according to the height setting information of the bullet chat display area and the current height position information of the target textView control in the bullet chat container object; according to the adjusted target textView control The height position information in the bullet chat container object displays the bullet chat in the video. The embodiment of the present invention effectively guarantees the accuracy of the barrage data.

A piece of high-precision dam deformation monitoring equipment and a measuring method belong to the field of measuring and monitoring. The equipment comprises a plurality of monitoring units. Each monitoring unit comprises an indium steel pipe system, and a transmitting device, a refracting device and a receiving device which cooperate with one another and are arranged along an optical path. Each indium steel pipe system comprises two indium steel pipes and length measurement position-sensitive sensors in one-to-one correspondence with the indium steel pipes, wherein the indium steel pipes are fixed at one measuring point of a measuring section, and the corresponding length measurement position-sensitive sensors are fixed at the other measuring point of the measuring section, and the corresponding indium steel pipes are connected through a moving pair with the measuring point at which the corresponding length measurement position-sensitive sensors are fixed. Through a plurality of monitoring units arranged in a triangular shape, dam deformation data is monitored and acquired from all measuring sections. The indium steel pipes of each indium steel pipe system are fixed at one measuring point, and the other measuring point is connected with the indium steel pipes through a moving pair. The noncontact mode of measurement and the stress-free mode of connection can eliminate deformation disturbance of the indium steel pipes caused by stress and ensure the accuracy of measurement.
