The system takes a computer control technology as a core, takes a power electronic switch technology as a basis, and adopts advanced technologies such as computer communication, an electronic information technology, automatic detection, a power electronic switch and the like to realize the interlocking of station signals. The object controller is a device for controlling an outdoor actuating mechanism (such as a turnout, a signal machine, a track circuit, a relay and the like), collects the state of the outdoor device, is a ground actuating part of an interlocking system or vehicle-vehicle communication, and is built into a safety control system together with the interlocking system or the vehicle-vehicle communication system to meet the requirements of relevant application scenes of railway or urban rail transit. To meet the requirements of a safety system, the object controllers communicate with the interlock system or the vehicle using a safety communication network and a safety protocol that meet the requirements of the safety communication and safety communication standard EN 50159.

The object controller miniaturizes, carries and electronizes the traditional relay combination, and can provide a flexibly configurable safety actuating mechanism for the applications of an interlocking system or a vehicle-vehicle communication system and the like.

According to the function of the object controller, the object controller can be divided into the following modules, the motherboard a and the motherboard B communicate with the outside through the communication red and blue network by the communication board a and the communication board B, as shown in fig. 2 specifically:

communication module (including communication board a and communication board B): the dual-system redundant output is adopted to be responsible for redundant communication with an interlocking host or a vehicle, and a communication protocol adopts a safe communication protocol; meanwhile, the communication module is communicated with the host module, and the communication protocol adopts a safety protocol;

the host module (including application software such as application software of the mainboard a and application software of the mainboard B) adopts a 2-by-2 architecture: the data 2 is taken as data 2, logic such as comparison, main-standby switching, application scheduling and supervision and the like are taken as data, and safety functions are guided under the condition of failure;

signal modules (e.g., 2X2 signal module An and 2X2 signal module Bn): the signal lamp is driven and the state of the lamp is collected, double-system redundant collection is adopted, single-system 2-out-of-2 comparison is needed, periodic self-checking is carried out, under the condition of failure, the module is guided to a safety side, and the 2X2 signal machine module An sends a pulse 422 signal to the 2X2 signal machine module Bn.

The method for restarting the all-electronic computer interlocking equipment can realize the function of automatically restarting the execution module software within a certain time when the execution module is down due to a certain accidental fault in the operation process of the execution module on the premise that the safety of the drive equipment of the execution module of the all-electronic computer interlocking equipment is ensured, thereby greatly improving the availability of the all-electronic computer interlocking equipment and reducing the unnecessary manual maintenance cost caused by the accidental fault.

Further, in an embodiment, the step S1 may specifically include:

and S11, detecting the running state of each execution module in real time according to the watchdog technology to acquire the historical downtime frequency of the ferroelectric memories stored in each execution module.

Optionally, because rail transit belongs to the high-safety industry, the requirements on the safety and the real-time performance of key data are extremely strict, and therefore, the execution module checks the running state of the execution module by using a watchdog technology, and meets the guarantee of real-time performance and safety.

The execution module uses a ferroelectric memory to store the historical downtime frequency, the safety level of ferroelectric reading, writing and verification needs to meet the SIL4 level, and the ferroelectric memory generally selects a chip with high reliability and high safety.

According to the all-electronic computer interlocking equipment restarting method provided by the invention, the execution module checks the running state of the execution module by using a watchdog technology, so that the real-time performance and the safety of monitoring the running state of the execution module can be ensured, and meanwhile, the requirements of high reliability and high safety can be met by using the ferroelectric memory historical downtime times.

Further, in an embodiment, the step S2 may specifically include:

s21, according to the software restarting process, restarting a first CPU in the target execution module, and restarting a second CPU in the target execution module when the starting time of the first CPU reaches a preset value;

s22, determining a starting password sent by the first CPU to the second CPU according to the starting information sent by the second CPU to the first CPU;

and S23, synchronizing the time of the first CPU and the time of the second CPU according to the starting password so as to determine the target time for restarting the first CPU and the second CPU, and restarting the first CPU and the second CPU at the target time simultaneously.

Optionally, when a downtime condition caused by software failure of each execution module occurs, the historical downtime times and the reason for the historical downtime are recorded, the size relationship between the historical downtime times and the preset times is judged, if the historical downtime times is smaller than the preset times, the software restart process is executed, and the target execution module with the failure is restarted. Specifically, the method comprises the following steps:

when the restarting process of the execution module is carried out, firstly, according to the software restarting process, a first CPU in a target execution module with a fault is restarted, and when the starting time of the first CPU reaches a preset value, a second CPU in the target execution module is restarted; secondly, obtaining a starting password fed back to the second CPU by the first CPU according to starting information sent to the first CPU by the second CPU; and according to the starting password, synchronizing the time of the first CPU and the second CPU to determine the target time for restarting the first CPU and the second CPU, and restarting the first CPU and the second CPU at the target time simultaneously.

For example, as shown in fig. 3, when the restart process is executed, the two CPUs (CPU0 and CPU1) are restarted at different timings, and the software program starts the CPU0 first, and starts the CPU0 for a while, and then starts the CPU 1. After the CPU1 is started, it will send the starting information to the CPU0, then the CPU0 sends the starting password to the CPU1, after the two CPUs exchange data, the synchronous time is calibrated, and it is appointed to start at a certain target time.

According to the restarting method of the interlocking equipment of the all-electronic computer, the two CPUs of the single board card of the execution module are utilized, and are started at the same appointed moment through a series of interactive processes, so that the correct operation of the execution module is guaranteed, and the stability of the interlocking equipment of the all-electronic computer is improved.

Further, in an embodiment, step S23 may further specifically include:

s24, if the first CPU does not receive the starting information sent by the second CPU after waiting for the first preset time, performing downtime operation on the first CPU;

and S25, if the second CPU sends the starting information to the first CPU and the second CPU does not receive the starting password sent by the first CPU after waiting for the second preset time, executing downtime operation on the second CPU.

Optionally, when the second CPU is restarted, the start information is sent to the first CPU, if the first CPU still does not receive the start information sent by the second CPU after waiting for the first preset time, the downtime operation is executed on the first CPU, and if the second CPU sends the start information to the first CPU and does not receive the start password fed back by the first CPU after waiting for the second preset time, the downtime operation is executed on the second CPU.

For example, as shown in fig. 3, if the CPU0 still does not receive the startup information sent by the second CPU after waiting for the first preset time, it is assumed that the CPU0 waits for a timeout, and at this time, a downtime operation is performed on the CPU 0. If the CPU1 does not receive the start password of the CPU0 after the CPU1 sends the start information to the CPU0 and waits for the second preset time, the CPU1 is considered to be timed out, and at this time, the downtime operation is performed on the CPU 1.

According to the method for restarting the interlocking equipment of the full-electronic computer, provided by the invention, the reasonable preset time is set, and the downtime operation is executed on the double CPUs after the double CPUs respectively exceed the preset time, so that the times of downtime of the double CPUs of the execution module can be monitored in real time, and meanwhile, the safe operation of the interlocking equipment of the full-electronic computer is ensured to the maximum extent.

Further, in one embodiment, if the downtime accumulated times exceeds the preset restart times, the first CPU and the second CPU are not restarted;

and determining the downtime accumulated times according to the downtime of the first CPU and the downtime of the second CPU.

Optionally, if the first CPU still does not receive the start information sent by the second CPU after waiting for the first preset time, performing a downtime operation on the first CPU, and if the second CPU sends the start information to the first CPU and does not receive the start password fed back by the first CPU after waiting for the second preset time, performing a downtime operation on the second CPU. And obtaining two CPU downtime accumulated times by counting the downtime times of the first CPU and the second CPU, judging whether the downtime accumulated times exceed the preset restarting times, and if the downtime accumulated times exceed the preset restarting times, not restarting the first CPU and the second CPU.

The method for restarting the interlocking equipment of the full-electronic computer provided by the invention has the advantages that the time of CPU accumulated execution downtime in each execution module of the interlocking equipment of the full-electronic computer is counted, and the restarting operation of the CPU is stopped when the time of CPU accumulated downtime exceeds the preset restarting time, so that the safe operation of the execution modules is ensured.

Further, in one embodiment, the operating status of each execution module includes at least any one of:

Optionally, in the normal operation process of each execution module of the switch machine in the all-electronic computer interlocking device, the operation state of each execution module is monitored in real time according to the software platform of each set up execution module, when the switch machine is in the control process, if the board card input is overtime due to two times out, the current of the unattached relay lasts for a first preset number of cycles, the current of the attracted relay does not last for a second preset number of cycles, the current is over-limited for a third preset number of cycles, the voltage is over-limited for a fourth preset number of cycles, the relay drive can not be attracted or can not fall down for a fifth preset number of cycles, the operation micro-cycle is overtime due to two times out of output data, the comparison of two times out of output data fails, the clock misalignment of double CPUs (such as a first CPU and a second CPU) in each execution module and the cycle numbers of the double CPUs in each execution module are inconsistent, and the like, the fault of the down machine can be caused, and recording fault information in time and updating the downtime frequency.

It should be noted that the first to fifth preset number of cycles may be set according to an actual operating environment, and for example, the first to fifth preset number of cycles may be all set to a same value, for example, N cycles, or set to different values, which is not specifically limited in the present invention.
