The invention discloses a multipoint temperature monitoring device and method of a high-voltage switch cabinet and relates to the field of automatic control monitoring. The device consists of two main parts, namely a temperature measuring module and a display panel module. The method comprises the following steps: the temperature sensor module converts temperature into a digital quantity and transmits temperature data obtained by conversion to a first single chip microcomputer, the first single chip microcomputer processes and packets the temperature data and then sends the data to a first radio-frequency transceiver and the first radio-frequency transceiver sends the processed data according to a wireless protocol; and a second radio-frequency transceiver receives the data sent by the radio-frequency transceiver, unpacks the data and transmits the data to the second single chip microcomputer, and the second single chip microcomputer processes the data and transmits the processed data to a display screen module for displaying the temperature data. The multipoint temperature monitoring device is based on a low-power-consumption design and is powered by a battery, is small in system volume, simple and flexible to install, stable in operation, flexible in expansion and low in cost. The multipoint temperature monitoring device can be expanded to other temperature measuring field.

The invention relates to the technical field of animal trap manufacturing, in particular to a clamping plate type mouse trapper. The clamping plate type mouse trapper comprises upper and lower clamping plates, a support, a spring and a handle, wherein a movable pedal is arranged on the surface of an interlayer lower clamping plate of the upper and lower clamping plates; an extension block is arranged in the middle of the left side wall of the other end of the movable pedal; the extension block of the movable pedal is connected to the side wall of a lower top of a linkage ejector rod on an upright rod support in an embedding way; a spring movable plate and a spring supporting rod structure are arranged on the upper part pf the upright rod support; an upper top of the linkage ejector rod is embedded into a connection spring plate; the connection spring plate is embedded into a groove in the left side wall of the upper clamping plate; a curved supporting rod is arranged on the front wall of the left surface of the movable pedal; after a mouse pedals the pedal, the pedal falls off, a linkage mechanism works, and the clamping plate rapidly falls to clamp the mouse. The clamping plate type mouse trapper has the advantages that the movable linkage ejector rod structure is adopted, the clamping plate rapidly falls to clamp the mouse by virtue of the pressure of the spring, the structure is simple, the trapping and killing capacities are strong, the efficiency is high, the cost is low, the setting is convenient, and safety and reliability are realized.
