The embodiment of the present application provides a method, device, electronic equipment, and storage medium for constructing a checker. Through the candidate standard parts provided by the standard part unit and the candidate tools provided by the shortcut tool unit, a three-dimensional model of the target checker is generated. By assigning attributes The unit determines the attribute information of the three-dimensional parts in the three-dimensional model, and splits the three-dimensional model according to the attribute information by analyzing the assembly unit to obtain at least one assembly file, and processes at least one assembly file through the drawing generation unit to obtain the target The two-dimensional drawing of the inspection fixture realizes the construction of the inspection fixture, simplifies the construction process of the inspection fixture, improves the construction efficiency of the inspection fixture, and reduces the construction cost of the inspection fixture.

The embodiment of the invention provides a facility safety management and control method and system. The facility safety management and control system comprises a management and control server and atleast one safety service subsystem which is in communication connection with the management and control server and is used for providing a safety protection service, and by sending a two-dimensional map image and three-dimensional scene image of a facility area to be managed and controlled to a user terminal currently used by management and control personnel for visual display, the management andcontrol personnel can carry out centralized management on all the safety service subsystems distributed in the facility area to be managed and controlled on the basis of the user terminal, so that themanagement and control difficulty of the facility area to be managed and controlled is reduced, and the management and control efficiency of the whole safety management and control process is improved. The position distribution information of each safety service subsystem in the facility area to be managed and controlled is recorded in the two-dimensional map image.

The invention relates to the field of mobile communication and discloses a mobile terminal and an antenna matching method thereof. In the invention, an antenna matching circuit is positioned on a mobile phone antenna, and the antenna matching circuit and the mobile phone antenna are integrally designed, so that the antenna can achieve the effect that the impedance of an effective frequency channel is approximate to 50 ohms at a feedback point connected with a circuit board of the mobile terminal. The mobile terminal and the antenna matching method thereof provided by the invention have the advantage of changing the condition that the traditional matching circuit is arranged on the circuit board of the mobile terminal and that new circuits are required to be designed to match the antenna of each frequency channel. Thus, the consistency of the batch production of the antenna and the matching circuit is well guaranteed, the development speed and cost of the circuit board of the mobile terminal can be shortened, and the management and control difficulties of the circuit board material are reduced.

The invention discloses a laterally-triggered hemostix. The laterally-triggered hemostix comprises an outer sleeve, an inner sleeve, a blood taking needle, an end cover and a trigger spring, wherein the upper end of the outer sleeve is open, and the lower end of the outer sleeve is provided with a needle outlet; the inner sleeve is arranged in an inner cavity of the outer sleeve and provided with two guide grooves; the blood taking needle is composed of a needle handle and a steel needle, two guide wings are arranged on the needle handle, and the blood taking needle is arranged in the inner cavity of the outer sleeve and penetrates through the inner sleeve; the end cover is fixedly mounted at the open end; the trigger spring is connected with the end cover and the needle handle; the side wall of the outer sleeve is provided with a trigger port, a limit table is arranged in the inner cavity of the outer sleeve, and the inner sleeve is movably supported by the limit table and is aligned with the trigger port; when the inner sleeve is located at a first position on the limit table, the two guide wings abut against the inner sleeve, and the blood taking needle is to be triggered; when the inner sleeve is located at a second position of the limit table, the two guide wings and the two guide grooves in the inner sleeve form sliding fit correspondingly, the blood taking needle moves towards the needle outlet under the action of the trigger spring, and triggered blood taking is realized. According to the hemostix, the component structure is simplified, and cooperation points among components are reduced.
