Problems solved by technology

[0003] However, the existing pressure sensors do not have the function of automatic switching without stopping
Take the oil pressure sensor as an example: during the operation of the ship, once the oil pressure sensor is damaged and cannot send out the oil pressure signal, the ship will stop without external control, and the ship is prone to the danger of capsizing after stopping at sea , resulting in irreparable damage
Even if external control is carried out to ensure that the diesel engine does not stop, the oil pressure in the oil passage is high, and the pressure sensor cannot be replaced under the condition of high-pressure oil
[0004] When the status information of the diesel engine cannot be obtained, there are risks to the operation of the diesel engine and the ship

Embodiment 1

[0050] like Figure 1 to Figure 4 As shown, a diesel engine oil pressure sensor device includes a base 1, a first pressure sensor 2 and a second pressure sensor 3 arranged on the base 1, and the base 1 is provided with a first detection channel 11, a second Two detection passages 12, communication passages 15 and medium entry passage 10; the detection end of the first pressure sensor 2 is set in the first detection passage 11; the detection end of the second pressure sensor 3 is arranged in the second detection passage 12; in the communication passage 15 The communication shaft 4 is provided, and the length of the communication channel 15 is greater than the length of the communication shaft 4; the base 1 is also provided with a power mechanism, and the power mechanism acts on the communication shaft 4 to move in the communication channel 15 to communicate with the first detection channel 11 and The medium enters the channel 10 or communicates with the second detection channel...

Embodiment 2

[0063] like Figure 5 As shown, a control method of a diesel engine oil pressure sensor device, the diesel engine oil pressure sensor device is the diesel engine oil pressure sensor device described in Embodiment 1, and in the initial state of the diesel engine oil pressure sensor device, the first pressure sensor Putting into use, the second pressure sensor is not in use, of course, the second pressure sensor can be put into use in the initial state, including the following steps:

[0064] Step S1, obtaining the medium pressure value collected by the first pressure sensor;

[0065] Step S2, judging whether the medium pressure value is within a preset range, the preset range is a pre-calibrated amount, and the case of not being in the preset range includes the case that the medium pressure value is too low or not collected;

[0066] Step S3, if no (the medium pressure value is not within the preset range), generate a corresponding control signal; if the medium pressure value ...

Abstract

The invention discloses a diesel engine oil pressure sensor device and a control method. The device includes a base, a first pressure sensor, a second pressure sensor, a power mechanism, a connecting shaft and a main control unit. The base is provided with a first detection channel , the second detection channel, the communication channel and the medium entry channel, the first pressure sensor is set in the first detection channel, the second pressure sensor is set in the second detection channel, and the communication shaft is set in the communication channel. In the initial state, the first pressure sensor is put into use, the first detection channel, the communication channel and the medium inlet channel are connected, and when the pressure value of the medium collected by the first pressure sensor is abnormal, the main control unit activates the second pressure sensor to control the action of the power mechanism to deactivate The communication shaft moves to connect the second detection channel, the communication channel and the medium inlet channel, so as to realize the automatic switching of the pressure sensor without stopping the machine. It can be seen that the present invention guarantees the reliability of the operation of equipment using the present invention, such as diesel engines.

Description

technical field [0001] The invention relates to the technical field of pressure sensors, in particular to a diesel engine oil pressure sensor device and a control method. Background technique [0002] Existing marine diesel engines are equipped with various pressure sensors, which are used to monitor various pressure values ​​of the diesel engine to ensure that the various pressures of the diesel engine are within the required range, thereby ensuring the reliable operation of the diesel engine. When there is a problem with the pressure value of the medium, the diesel engine will send out an alarm signal to remind the crew on board to check the diesel engine. If the pressure value is too low or disappears, the diesel engine will alarm and stop without external control. [0003] However, none of the existing pressure sensors has the function of automatic switching without stopping. Take the oil pressure sensor as an example: during the operation of the ship, once the oil pres...
