Problems solved by technology

If the two systems are to be integrated into one system, there are the following problems: 1) When the system is powered on, due to the different starting speeds of the components of the two systems, system startup disorder will occur; 2) After the system is powered on, due to Functional requirements, when only one set of photoelectric system functions is used, the useless power consumption of the system will be particularly large and the loss of the other set of systems; 3) If electronic components are added, this will also help the synthesis to a certain extent, but the volume and weight also need to be increased

Embodiment 1

[0034] Example 1: System 1 is powered on alone, and System 2 does not work; according to the attached figure 2 Shown:

[0035] First stage: When APP1 is closed and APP2 is open, the Kp relay is closed, which is equivalent to the closure of switches K1 and K2. At the same time, the relay Ks is closed, which is equivalent to the closing of the switch K3. After K1 is closed, the high-power components of system 1 start to supply power. K3 is closed, the SBC, PCC of the second stage, and the control components of the third stage are all powered on, and the control unit is also powered on at the same time.

[0036] Second stage: The 5V generated by PCC conversion is respectively connected to the input terminal of the photoelectric isolator and Kp input 2. Since APP2 is not closed, the control of the photoelectric isolator is high, and the light-emitting diode of the photoelectric isolator is not conducting. The output of the isolator is low level, and the SBC detects that APP2 i...

Embodiment 2

[0039] Example 2: System 2 is powered on independently, and System 1 does not work; according to the attached figure 2 Shown:

[0040] First stage: When APP2 is closed and APP1 is disconnected, the relay Ks relay is closed and Kp is disconnected, which is equivalent to the disconnection of switches K1 and K2 and the closure of switch K3. After K1 is disconnected, the high-power components of system 1 will not be powered on. K3 is closed, the SBC, PCC of the second stage, and the control components of the third stage are all powered on, and the control unit is also powered on at the same time.

[0041] Second stage: The 5V generated by PCC conversion is respectively connected to the input terminal of the photoelectric isolator and the input 2 of Kp. Since APP2 is closed, the photoelectric isolator outputs a high level, and SBC detects that APP2 is closed. K2 is disconnected, the power-on detection of system 1 is low level, and the SBC detects that APP1 is not closed. The SB...

Embodiment 3

[0044] Embodiment 3: system 1 and system 2 work simultaneously; According to attached figure 2 Shown:

[0045] The first stage: when APP1 and APP2 are closed at the same time, the relays Ks and Kp are closed, which is equivalent to the closure of switches K1, K2, and K3. K1 is closed, and all electronic units of System 1 are powered on. K3 is closed, the SBC, PCC of the second stage, and the control components of the third stage are all powered on, and the control unit is also powered on at the same time.

[0046] Second stage: The 5V generated by PCC conversion is respectively connected to the input terminal of the photoelectric isolator and the input 2 of Kp. Since APP2 is closed, the photoelectric isolator outputs a high level, and SBC detects that APP2 is closed. K2 is closed, the power-on detection of system 1 is high level, and SBC detects that APP1 is closed. The SBC detects the power-on status of the APP, and judges the task requirements for system 1 and system 2 t...

Abstract

The invention provides a dual-system electrification control circuit and a control method thereof. Based on an original system, similar electronic assemblies of two electro-optical systems are integrated, but new electronic assemblies are not added, and the size, weight and cost of a whole system can be greatly decreased. A multi-stage electrification system is adopted, the first-stage system adopts an analog circuit consisting of an APP switch and an electromagnetic relay, and the reliability and safety of a power supply system can be effectively improved. The second-stage system adopts timing sequence electrification control, system disturbance produced by different starting times of the system after electrification can be avoided. The third-stage system adopts digital IO control and isflexible to control, the system can be in different working states according to different execution tasks, and the power consumption and loss of the system can be effectively reduced by powering off excessive electronic assemblies. The dual-system electrification control circuit adopts the APP switch and is simple in operation and suitable for wide popularization.
