An intelligent door lock control system based on the mobile communication technology comprises a lock body, a control module and an operation end. The control module is arranged in the lock body. The operation end is in communication with the control module. The lock body comprises a shell, a mechanical lock cylinder arranged in the shell, an electromagnet, and an awakening operation button arranged on the surface of the shell. The control module comprises first data processing units which are in communication, and a first storage unit and a first communication unit which are used for storing unlocking information. The operation end comprises a man-machine operation interface, a second communication unit, a clock chip, a second storage unit, an electronic cipher calling unit and a second data processing unit. By arranging a mechanical unlocking system and an intelligent unlocking system at the same time, unlocking can be achieved through electronic ciphers when a user forgets to bring a key, unlocking information can be recorded, and the security of the unlocking systems is ensured.

The invention relates to an oil field well workover treatment tool, in particular to hydraulic tongs capable of realizing the automatic loading / unloading of an oil pipe and a sucker rod. The hydraulictongs comprise main tongs, back tongs, a high-low-speed gear shift mechanism and a connecting support. The back tongs are arranged on the connecting support; the main tongs are positioned above the back tongs and are connected with the back tongs through a guide bar; and the main tongs can reciprocate up and down along the guide bar. The high-low-speed gear shift mechanism is arranged on the maintongs; the output end of the high-low-speed gear shift mechanism is connected with a gear shift device inside the main tongs; and the high-low-speed gear shift mechanism is also connected with a hydraulic control module. The hydraulic tongs are connected with a hydraulic tongs telescopic bracket of the machine body of the well workover machine through the connecting support. The hydraulic tongs are driven by the telescopic bracket to realize automatic telescoping, thereby freeing operators from a dangerous operating environment. Automatic operation is realized for the loading / unloading of thehydraulic tongs, thereby not only reducing the labor intensity of workers, but also avoiding possible accidental injury of workers during the operation.

A monitoring control method and system (10) for the load capability of a battery. The system comprises a control unit (11) and a measurement load unit (12). The control unit and the measurement load unit are respectively connected in parallel to a battery (20) to be tested. The measurement load unit comprises a measurement load (121) and a measurement load switch drive circuit (122) connected to the measurement load. The measurement load switch drive circuit is connected to the control unit, and is used for receiving a first control signal sent by the control unit and controlling, according to the first control signal, the measurement load to be connected or disconnected to the battery. By means of the monitoring control method and system for the load capability of a battery, the floating voltage of the battery can be effectively avoided, the accuracy of the voltage detection of the battery can be improved, and the remaining capacity of the battery can be more stably displayed.

The invention discloses a downhole movable slurry casting device and method. The device comprises a caterpillar-band chassis mechanism, a slurry casting mechanism and a monitoring module; the slurry casting mechanism comprises a feeding structure and a slurry preparing mechanism, the caterpillar-band chassis mechanism comprises a chassis, a caterpillar band and a caterpillar band driving module, and the monitoring module comprises a main controller, a feeding monitoring module, a water inlet monitoring module, a motor power supply control module, a first wireless radio frequency module and a liquid crystal touch screen. The method comprises the following steps of 1, building a mine map and moving the caterpillar-band chassis mechanism; 2, checking and connecting the slurry casting mechanism; 3, preparing and delivering the slurry through the slurry casting mechanism. The downhole movable slurry casting device is reasonable in design and easy to operate; the movement of the caterpillar-band chassis mechanism drives the slurry casting device to move, and labor and material resources are saved; by monitoring the aqueous slurry in real time, the concentration and mass of the slurry areensured, and the practicability is high.

The invention relates to an oil field operation device, in particular to an oil field workover treatment machine. The machine body is arranged on a hydraulic load-bearing traveling gear and is interlocked with the hydraulic load-bearing traveling gear. Hydraulic tongs connected with a telescopic bracket on the machine body can be extended out and retracted with the telescopic bracket. A clip seatis positioned below the hydraulic tongs and is arranged on a well head. An elevator which is suspended onto the machine body can reciprocate up and down. A faucet is positioned above the machine bodyand the clip seat; a pipe throwing device is arranged on the faucet and the machine body; and a clip unlocking device and a clip locking device corresponding to the elevator are arranged on the clip seat and the pipe throwing device respectively. A righting mechanism and a valve mechanism are further arranged on the faucet. A control cabinet is arranged on the machine body; and the clip seat, thehydraulic tongs, the elevator and the pipe throwing device are connected with a control system in the control cabinet respectively. The oil field workover treatment machine can be assembled and disassembled conveniently and rapidly, thereby not only facilitating transportation, but also changing the positions to meet the requirements of different work. Simultaneously the machine can be laid freely at a well field according to the practical conditions.

The invention relates to the field of alternating-current power source monitoring and measuring, and especially relates to a low-voltage switchgear feeder monitoring and measuring device. The device has functions like feeder switching status, feeder alarm tripping status, feeder current measurement, bus voltage measurement, feeder control output and communication. The device is installed on a low-voltage switchgear feeder screen to achieve a four-remote control function, and can be conveniently connected to an integrated automation system. The low-voltage switchgear feeder monitoring and measuring device adopts an M430F2491 embedded microcontroller controller as a core processor to monitor feeder switching status, feeder alarm tripping status, feeder current measurement, bus voltage measurement, feeder control output, communication and the like; the device integrates the functions of multiple pieces of original feeder measuring and monitoring equipment, and therefore, low-voltage switchgear feeder monitoring is more concise, and the level of automation is improved; and the device is integrated with the function of communication, so that operators can easily monitor the power and status of a low-voltage switchgear feeder and remotely control the tripping of a feeder branch.
