The invention provides a resource access control method and device, electronic equipment, a computer readable storage medium and a computer program product. The method comprises the steps that under the condition that a resource access request initiated by a target object is received, a target expression matched with the target object is acquired from a permission language library; obtaining metadata information associated with the target object, and generating a query statement based on the metadata information and the target expression; and accessing a resource library based on the query statement to obtain target resource information used for responding to the resource access request. According to the method and the device, the calculation amount for matching and filtering the data can be greatly saved, so that the resource access efficiency can be effectively improved.

The invention discloses a DDS protocol-based participant matching method and a related device, and relates to the technical field of communication. Comprising the steps of obtaining a first parameter table, a second parameter table and first data of a target participant; judging whether the address of the first participant is located in a first parameter table or a second parameter table; if the address of the first participant is located in the first parameter table, determining that the first participant is matched with the target participant; if the address of the first participant is located in the second parameter table, judging whether the first participant is matched with the target participant based on the first data; and if the address of the first participant is located outside the first parameter table and the second parameter table, determining that the first participant is not matched with the target participant.

In this method, firstly, the number of standard precision roads corresponding to each high-precision road in the standard precision road in the high-precision map framework is determined by a predefined road matching algorithm, and then for those high-precision roads whose corresponding number of standard precision roads exceeds the road number threshold, the navigation road attributes of the high-precision road are assigned according to the ratio between the length of each standard precision road and the length of the high-precision road and the navigation road attributes, thereby obtaining the target high-precision road. Through this method, the cost of making high-precision maps can be effectively reduced.

A direct current contactor capable of executing large current breaking for multiple times comprises a shell, a driving system, a contact system, an electronic ignition assembly and a telescopic action execution assembly. The action execution assembly is arranged in the shell corresponding to the movable contact plate; the electronic ignition assembly is arranged at the top of the shell corresponding to the action execution assembly; the electronic ignition assembly comprises an electronic ignition tube shell and at least two electronic ignition tubes, and an exhaust channel communicated with the exterior of the shell is formed in the shell wall of the electronic ignition tube shell. The action execution assembly is in sealing contact with the inner wall of the electronic ignition tube shell, and when the contact system is normally switched on and switched off, one end of the action execution assembly located in the electronic ignition tube shell seals the exhaust channel; in a normal working state, the action execution assembly and the electronic ignition assembly do not act, and the driving system drives the contact plate to move, so that the contact system performs normal opening and closing. Through the multiple independent electronic ignition tubes and the exhaust channels, multiple times of large-current breaking are achieved, and the breaking capacity and the utilization rate of the contactor are improved.
