Low-temperature starting system of double-section crawler-type all-terrain armored car

The invention discloses a low-temperature starting system of a double-section crawler-type all-terrain armored car. The low-temperature starting system is connected with an engine cooling system through an electromagnetic valve, the low-temperature starting system and the engine cooling system are connected when low-temperature heating is needed, the low-temperature starting system and the engine cooling system are automatically cut off in other conditions, connection is stable and reliable, and it is ensured that the failure rate of a vehicle cannot be increased due to the heating system. A seventh water flow sensor, an eighth water flow sensor, a ninth water flow sensor and a four-way pipe with flow distribution are used for carrying out flow distribution on engine oil, a battery and an engine body according to respective required heating amounts, so that a very good heating effect is ensured to be achieved; a heater controller with program setting can realize reserved timing heating, real-time heating, hea
