and controlling each device according to each subsystem starting matrix based on time, the start-stop logic matrix after optimization and adjustment and each system running state.

As long as a control start signal is input, the method considers that an instruction for starting the subsystem exists; only when all the start signals are removed will the method consider that the subsystem is to be stopped.

The system operation state detection comprises the health state of the operated equipment and the state of the equipment at the previous stage of the equipment to be started.

The health state of the operated equipment can be judged by the operation state and the feedback state in the real-time state matrix, and the judging method is as follows:

when the number of devices is greater than 1, and x in the device matrix _n3 、x _n4 All are different: the health status of all the devices is the result of the running status and feedback status phases in the real-time status matrix

When the number of devices is greater than 1, and x is in the device start-up matrix _n3 、x _n4 When the same parameters exist:

first, x in the adjusted start-stop logic matrix Q _n3 、x _n4 Adding, and calculating the delayed starting time;

Further, the previous stage device state is realized by the following algorithm:

first, the number of devices in each subsystem is queried and then calculated:

When the number of devices is 0: the previous stage device states were all 0 (not ready)

When the number of devices is 1: the device state of the first device previous stage is set to 1 (ready)

When the number of devices is greater than 1, and x is in the device start-up matrix _n3 、x _n4 All are different: the state of the device at the previous stage of the first device is directly set to be 1 (ready), and the device at the previous stage with the number larger than 1 is setThe standby state is set to the health state of the previous stage device.

When the number of devices is greater than 1, and x is in the device start-up matrix _n3 、x _n4 When the same parameters exist: the device state of the first device previous stage is directly set to 1 (ready), and the device state of the device previous stage with the number larger than 1 is set according to the following procedure.

the second step is to compare the starting time of the second step with the starting time of the previous-stage equipment in the system, and if the starting time of the second step is longer than the starting time of the previous-stage equipment, the second step is set to be the health state of the previous-stage equipment; if the starting time of the first-stage equipment is equal to the starting time of the first-stage equipment, continuing to inquire the starting time of the first-stage equipment, and reciprocating until the starting time of the first-stage equipment is larger than the starting time of the inquiry number equipment or the number of the first-stage equipment is inquired.

Further, after receiving the start signal, each subsystem calculates the start time of each device, reaches the start time and the previous stage device is in ready state, and starts each device in sequence. When any one device in the system fails, the system stops all the devices; when the system detects that the previous-stage equipment has sent a control instruction but is not in a healthy state, the next-stage equipment can report that the previous-stage equipment has no feedback fault, and the system can stop all the equipment.

Thus doing soThe sequence of the serial numbers of the devices is the regular arrangement according to the priority starting time from big to small and the lag starting time from small to big, and at least one of the two times is 0, and the sequencing flow is shown in figure 5.

Further, the start-stop logic matrix is optimally adjusted according to the subsystem equipment quantity matrix, so that the optimally adjusted start-stop logic matrix is obtained. The rules are as follows:

preferential start time q _n3 Delay start time q _n4 Are all 0, q _n3 Adjusted to q where the first device serial number in S represents a device _n3 。

Preferential start time q _n3 Is not 0, lag start time q _n4 Is 0, q _n3 Adjusted to q where the first device serial number in S represents a device _n3 Q of the present device _n3 。

Preferential start time q _n3 0, lag start time q _n4 Not 0, qn4 is adjusted to q where the first device serial number in S represents the device _n3 Q of the apparatus _n4 。

After the automatic adjustment of the starting time, the starting-stopping logic matrix is changed into an optimized starting-stopping logic matrix:

，

further, the method executes the steps according to the input device start-stop logic matrix when the method starts, and when the start-stop logic of any device changes, the method re-executes the steps to cope with the change of the start-up logic, and the flow is shown in fig. 6.

Specifically, the method provides control logic of a subsystem, and realizes linkage control of networking equipment in each system according to a start-stop logic matrix Q, an equipment serial number matrix S, a subsystem quantity matrix S1, a real-time state and control signals of each subsystem after time adjustment. Comprising the following steps:

detecting a control signal in real time;

detecting the running state of the system;

and starting and stopping the devices in the subsystem.

The real-time detection of the control signals, wherein each subsystem control signal in this example may receive 16 a control signal of a different source, including but not limited to the following: the method comprises the steps of (1) high and low level signals (2), leading signals (3) 485 communication given signals (4) CAN given signals (5) and other equipment operation feedback signals.

Further, as long as there is a control start signal input, the method considers that there is an instruction to start the subsystem; only when all the start signals are removed will the method consider that the subsystem is to be stopped. In the method, the control signal of the No. 1 subsystem is a pilot signal or a 485 communication given signal, K1 becomes 1 when the pilot signal is input or the 485 communication given signal is input, the method considers that an instruction for starting the No. 1 subsystem is sent, and the method stops the No. 1 subsystem only when the pilot signal and the 485 communication given signal are not input and K1 becomes 0.

The subsystem operation state detection, wherein the real-time state of each device in the present example includes a health state and a device state of the device prior to a start-up sequence in the subsystem.

The health state can be judged by the feedback state of the equipment in the system, and the judging method is as follows:

when the number of subsystem devices is greater than 1, q is in the device matrix _n3 、q _n4 All are different: the health state of the equipment in the subsystem is set as the feedback state of the equipment;

in the method, subsystem 2 comprises 4 devices q _n3 、q _n4 All of them are different from each other,

the health status of the device No. 8 is set as the feedback status of the device No. 8;

the health status of device No. 9 is set to the feedback status of device No. 9;

the health status of the device No. 11 is set to the feedback status of the device No. 11;

the health status of device No. 2 is set to the feedback status of device No. 2.

When the number of devices is greater than 1, q in the device start matrix _n3 、q _n4 When the same parameters exist, the health states of the same parameters, namely the same starting time sequence level, need to be mapped to the health states of the next device after the words of the time sequence level. The method comprises the following steps:

the health status of the first device in the subsystem is set to the feedback status of the device

First Q in the regulated start-stop logic matrix Q _n3 、q _n4 Adding, and calculating the delayed starting time;

the second step is to compare the starting time of the device with the starting time of the device at the previous stage in the system, and if the starting time is longer than the starting time of the device at the previous stage, the feedback state in the real-time state matrix is set to be a healthy state; and if the starting time of the previous-stage equipment is equal to the starting time of the previous-stage equipment, setting the logic sum of the health state of the previous-stage equipment and the received feedback state of the self equipment as the setting health state.

In the method 1, 7 devices q are arranged in a subsystem _n3 、q _n4 The same parameters exist;

the health status of the device No. 6 is set as the feedback status of the device No. 6;

the health status of device No. 3 is set to the feedback status of device No. 3;

the health status of device No. 4 is set to the logical sum of the feedback status of devices No. 3 and No. 4;

the health status of device No. 5 is set to the logical sum of the feedback status of devices No. 4 and No. 5;

the health status of the device No. 1 is set as the feedback status of the device No. 1;

the health status of device No. 7 is set to the logical sum of the feedback status of devices No. 7 and No. 1;

the health status of device No. 12 is set to the logical sum of the feedback status of devices No. 12 and No. 7.

First, the number of devices in each subsystem is queried and then calculated:

When the number of devices is greater than 1 and qn3 and qn4 in the device start matrix are different, the device start matrix is: the state of the first device prior stage is directly set to 1 (ready), and the state of the device prior stage with the number greater than 1 is set to the health state of the prior stage.

The previous stage device state of device No. 8 is set to 1;

the previous-stage device state of the device No. 9 is set to the health state of the device No. 8;

the previous-stage device state of the device No. 11 is set to the health state of the device No. 9;

the previous stage device status of device No. 2 is set to the health status of device No. 11.

When the number of devices is greater than 1, q in the device start matrix _n3 、q _n4 When the same parameters exist: the state of the first device prior stage is directly set to be 1 (ready), and the state of the device prior stage with the number larger than 1 needs to be inquired out of the state of the device prior stage starting time sequence, and the method is as follows:

the previous stage device state of device No. 6 is set to 1;

the previous-stage device state of the device No. 3 is set to the health state of the device No. 6;

the previous-stage device state of the device No. 4 is set to the health state of the device No. 6;

the previous-stage device state of the device No. 5 is set to the health state of the device No. 6;

the previous-stage device state of the device No. 1 is set to be the health state of the device No. 5;

the previous-stage device state of the device No. 7 is set to the health state of the device No. 5;

the previous-stage device state of the device No. 12 is set to the health state of the device No. 5;

further, after receiving the start signal, each subsystem calculates the start time of each device, and the device state of the previous stage is normal (with operation feedback) when the start time is reached, and starts each device in sequence. When any one device in the system fails, the system stops all the devices; when the system detects that the previous-stage equipment has sent a control instruction but is not in a healthy state, the next-stage equipment can report that the previous-stage equipment has no feedback fault, and the system can stop all the equipment.
