The portable safety protection device adopts a compatible modularized design, can configure corresponding functional modules according to actual requirements, and can also rapidly maintain equipment through module replacement; the design of key equipment of the system part meets the waterproof grade IP65, and the system can work under various extreme conditions such as humidity or rain. And a large-capacity power supply is adopted to continuously work for 24 hours, so that long-time rush repair and maintenance of the railway are met.

The present embodiment also relates to a portable safety protection method for track traffic construction, and an embodiment of the protection method is described below in connection with a plurality of scenes of a train operation control system.

From analysis in the aspect of track traffic construction, risk sources endangering the life safety of constructors include: high voltage electricity and fast moving trains or dumb cars. The existing train control technology has a plurality of control modes of semi-automatic blocking, automatic blocking and moving blocking, and the train runs to carry out safety protection on the train or the intrusion of foreign matters through safe and reliable technical means. Based on the existing train operation control systems (C3, C2 and C1 and novel train Control (CN) lines) and the moving blocking system (CBTC and TACN lines) of urban rail transit, the safety protection design is carried out on the rail transit construction area from the scene angle of the train operation control systems. The following scenario is specifically shown in fig. 5:

scene one: for train approaching protection, the railway operation modes in China are different, and track circuits are adopted in the stations and the station approaching sections to judge the occupation and the clearing of the track sections so as to adapt to the application of different places. By utilizing the working principle of a track circuit, the construction portable safety protection device is connected with two steel rails in a construction area to enable a track relay to fall down, so that a train cannot approach and break into the construction area.

As shown in fig. 2, the line is divided into several sections, and each section is provided with a track relay for detecting whether the section is occupied by a vehicle. When no train runs in the section, current can flow from the power supply through the track via the track relay coil, excitation is enabled to be absorbed, the section is idle, and the train can safely run into the section. When a train enters the blocking section, current moves through the train axle instead of flowing through the track relay, the relay coil loses magnetism and falls down due to power failure, the section is occupied, and at the moment, the train cannot enter the section. If the track breaks, the excitation loop of the track relay is disconnected, so that the track relay loses magnetism, and the running safety of the train can be ensured. When the train leaves the section, the track relay is excited and sucked up again, so that the section is idle, and other trains can enter the section.

The construction portable safety protection device adopts a rail circuit protection principle, the fully-closed high-pressure crocodile clips of the construction portable safety protection device are respectively connected with the bottoms of two rails of a construction area, and then a switch K on the construction portable safety device is closed, so that a rail relay of the construction area falls down, and a train cannot enter the area at the moment, so that the train approaching safety protection of the construction area is achieved.

Scene II: as shown in fig. 3, a subway line of CBTC, a C3 line of RBC control and a new train Control (CN) line all adopt a mobile blocking train control mode based on wireless communication, and a train performs bidirectional data communication with ground equipment mainly through modes such as train-ground wireless communication GSM-R, LTE. The regional controller ZC (CBTC line) or radio block center RBC (national railway C3 and CN line) of the trackside signal equipment room monitors and manages train operation in jurisdiction in real time, calculates train operation permission curve and movement authorization terminal point EOA in jurisdiction, the train needs to safely operate under the running permission curve, stops before the EOA, otherwise, emergency braking can be performed. And each train has an automatic safety protection (AP for short) envelope for protection, and all trains cannot intrude into the AP envelopes of other trains. Emergency braking can be caused if the train breaks in, so that the running safety of the train is ensured. For the non-communication area, the non-recognition protection area (NIAP) is marked, and the train cannot break into the protection area.

After entering a planned construction area, the positioning position and the construction range of the BDS/GPS system are forwarded in real time or manually input into a construction position kilometer post through a construction portable safety protection device to be sent to ZC or RBC for controlling the running of the train, and a construction protection area NIAP envelope is formed in the construction area to prevent other trains from intruding into the construction area.

The existing train control systems are CBTC systems, wireless communication module systems in tunnels of the lines cannot be covered, constructors can manually input kilometer posts of construction areas, and the construction areas are sent to signal systems through wireless channels such as LTE, special wireless AP and waveguides, so that protection areas can be effectively formed.

After the track section occupation and the construction area are set, the train occupation can be displayed in the track section or the moving blocking area of the construction area of the train dispatching interface, a dispatcher is reminded of the construction operation in the area, the dispatcher can conveniently and intuitively determine the construction range, and the train running control system can effectively prevent trains from rushing into the construction area.

Scene III: as shown in fig. 4, the local freight railway train control system is generally simpler, a railway circuit is not arranged in a section, the train can not be accurately positioned in real time, the running speed of the train is generally not more than 120KM/h, in this case, the running speed of the train is relatively slow, a near-distance obstacle infrared detection technology is adopted, a train with the speed more than 200M can be protected from approaching and gives an audible alarm, constructors in a construction area can hear the alarm to withdraw from a dangerous area in advance, and the constructors are ensured to have a time window for withdrawing from the safe area for at least more than 6S. Meanwhile, the two sides of the portable safety protection device are provided with red signal panels for train forbidden operation signals, the red signal panels are composed of low-energy-consumption LED dot matrixes, the effective distance is more than 400M, drivers without ATP or manual driving trains can effectively see forbidden lights at a long distance to take braking measures to stop, and the drivers are prevented from intruding into a construction area.

The safety is an insurmountable red line of railway and rail transit, and the running safety of the train and the safety of maintenance personnel are the mission of a train running control system through various means. The portable safety protection device is not only the safety protection device for outdoor operations such as maintenance and construction of railway and urban rail transit system equipment, but also the safety protection means of construction operation is enhanced, the working intensity of guardians is lightened, and the equipment gap of the safety protection device in a construction area is filled.
