The invention discloses a method and a system for identifying abnormal working conditions of a hydrogen tube bundle vehicle. The method comprises the following steps: acquiring monitoring parameters of the tube bundle vehicle; according to the tube bundle vehicle monitoring parameters, tube bundle vehicle working conditions are recognized, and the tube bundle vehicle working conditions comprise the transportation working condition, the filling working condition and the unloading working condition; and according to the monitoring parameters of the tube bundle vehicle, abnormal events in different working conditions of the tube bundle vehicle are identified. According to the invention, abnormal working condition identification of the hydrogen tube bundle vehicle under all working conditions is realized.

The utility model relates to the technical field of switch cabinets, in particular to a switch cabinet environment intelligent control system which comprises a cabinet body, a controller is arranged on the outer wall of the cabinet door, a temperature and humidity sensor is arranged in the cabinet body, a heater is installed on the inner side of the cabinet door, an opening is formed in one side of the cabinet body, and a temperature and humidity sensor is arranged on the other side of the cabinet body. The inner side of the opening is connected with two sets of heat dissipation fans through a supporting frame, a heat dissipation net is detachably installed at the opening, the controller controls the heater to heat the interior of the cabinet body, when the temperature and humidity sensor collects that the temperature of the cabinet body is higher than a set value, the two sets of heat dissipation fans are started to operate, and the temperature is reduced under cooperation of the heat dissipation net. The temperature and humidity condition in the cabinet body can be monitored conveniently, automatic processing is carried out, the heat dissipation net and the cabinet body can be disassembled by pressing a pressing block towards the middle and leaving a locking column from a locking hole, the heat dissipation net and the cabinet body are disassembled conveniently, workers can disassemble and assemble the heat dissipation net and the cabinet body conveniently, the heat dissipation net is cleaned or replaced conveniently, and the service life of the heat dissipation net is prolonged.

A backhoe loader is used for prying and cleaning, material crushing, and collecting and loading materials in mine tunnels. It consists of a working mechanism, a cab operation control mechanism, a hydraulic control system, an electrical control system, a vehicle chassis travel mechanism, and a material conveying mechanism; the crushing device and bucket assembly of the working mechanism are hingedly assembled on the forearm with a connecting rod assembly, and the bucket assembly cooperates with the material conveying mechanism to complete the slag removal and loading operations. The backhoe loader of the present invention stops at a relatively safe position to operate, so as to achieve the prying and cleaning and crushing operations in the tunnel, the material excavation, collection, and loading operations. The maximum operating section can reach 7.0 meters × 7.0 meters, and the operator can be at most 6.0 meters away from the material excavation, prying, cleaning, and crushing operations. It can effectively avoid the dangers caused by unpredictable factors such as large space in the mining area, poor safety protection performance, and easy occurrence of landslides and falling rocks, and prevent casualties caused by manual or mechanical operations.
