Detailed Description
The utility model is further described below in connection with the examples, which are not to be construed as limiting the utility model in any way, but rather as falling within the scope of the claims.
Referring to fig. 2-5, the diesel engine monitor of the present utility model includes a housing, an operation panel, a main control module, an antifreeze and oil heating control module, a temperature discharge monitoring module and a pressure monitoring module. The operation panel is provided with a power switch 9, an antifreezing solution heating switch 10, an oil heating switch 11, a pre-lubrication starting switch 12, a machine side/remote control mode switch 13 and an air-break valve switch 14.

As shown in fig. 3, the antifreeze and oil heating control module includes an antifreeze heater, an engine oil heater, a first ac contactor KM1, and a second ac contactor KM2. The antifreeze heater is arranged in the diesel engine circulating waterway and is electrically connected with an alternating current power supply through a first alternating current contactor KM 1. Specifically, the common terminal and the normally open terminal of the first ac contactor KM1 are respectively connected to the antifreeze heater and the live wire of the ac power supply in one-to-one correspondence. Wherein the alternating current power supply provides three-phase alternating current. A circuit breaker is also arranged on the power supply line of the alternating current power supply. One end of the coil of the first alternating current contactor KM1 is connected with a zero line of an alternating current power supply. The other end of the coil of the first alternating-current contactor KM1 is connected with a live wire of an alternating-current power supply through an antifreezing solution heating switch SA1, and the antifreezing solution heating switch SA1 is arranged on an operation panel.

When the diesel engine is in a low-temperature environment, the antifreeze heating switch SA1 on the operation panel is turned to be in an on state, coils of the first alternating current contactor KM1 and the second alternating current contactor KM2 are attracted, so that the internal switches of the first alternating current contactor KM1 and the second alternating current contactor KM2 are conducted, and the two heaters are electrically operated.
When the antifreeze and the engine oil are heated to the set temperatures, the heating is automatically stopped. The automatic control means belongs to the common technical means in the field, so that no further discussion is made. In addition, the diesel engine does not need to start the heating function of oil and antifreeze under the running state.
In order to facilitate staff to learn the current working state of the heater, the live wire of the alternating current power supply is electrically connected with the zero line of the alternating current power supply through a first warning lamp HL1 and a switch end of a first alternating current contactor KM1 which are connected in series.

In addition, the off-gas control module also provides for on-site operation and remote operation modes. The remote signal for the remote operation mode may come from a remote console or an electronic control room. The remote trigger switch may employ a relay/contactor accordingly. The arrangement of the two operation modes greatly improves the reliability of the emergency stop operation of the diesel engine.
