Abstract

[Problems to be solved]

To provide a solenoid valve control device in which a user, or the like, can preciously grasp a state of the solenoid valve based on the number of operations of the solenoid valve.

[Solution]

The solenoid valve control device 13 controls the solenoid valve 12 and includes a storage unit 136 storing the number of operations concerning opening/closing of the solenoid valve 12, and a transmission unit 132 externally transmitting the number of operations stored in the storage unit 136. When the number of operations stored in the storage unit 136 becomes equal to or greater than the limitation number of times concerning a life of the solenoid valve 12, the transmission unit 132 externally transmits an alarm signal.

Claims

1. A solenoid valve control device controlling a solenoid valve, comprising;

a storage unit storing a number of operations concerning opening/closing of the solenoid valve, and

a transmission unit externally transmitting the number of operations stored in the storage unit.

2. The solenoid valve control device according to claim 1,

wherein, when the number of operations stored in the storage unit becomes equal to or greater than the limitation number of times concerning a life of a solenoid valve, the transmission unit externally transmits an alarm signal.

3. The solenoid valve control device according to claim 2,

wherein the limitation number of times is the number of operations acceptable on durability of the solenoid valve.

4. The solenoid valve control device according to claim 1,

wherein the number of operations is any one of the number of times of opening, the number of times of closing, and the number of times of energizing of the solenoid valve.

5. The solenoid valve control device according to claim 1,

wherein the transmission unit externally transmit by LIN communication or CAN communication.

6. The solenoid valve control device according to claim 1,

wherein the storage unit is a non-volatile memory.
